Building a Profitable Window Cleaning Business

Window cleaning offers exceptional business opportunity: low startup costs, consistent demand, and steady recurring income. Here’s your complete guide to building a profitable window cleaning business with reliable earnings.

---

Here’s a fascinating question: what business can you start with £200-£500 investment, build to £30,000-£50,000 annual income within a year, and run solo with minimal overheads?

Window cleaning.

It’s one of the most accessible yet profitable service businesses you can build. The barriers to entry are low (equipment costs hundreds, not thousands). The demand is constant (windows get dirty year-round). The income is recurring (regular customers pay month after month). And the business model scales beautifully (from solo operation to multiple teams).

But here’s what you need to understand: whilst entry is easy, building a successful, profitable window cleaning business requires more than just a squeegee and a bucket. You need proper technique (streak-free results aren’t accidental), efficient systems (for building and maintaining your “round”), pricing strategies that maximise profit whilst remaining competitive, and customer retention approaches that create reliable recurring income.

The window cleaners earning £40,000-£60,000 annually aren’t working harder than those earning £20,000 – they’re working smarter. They’ve built efficient rounds with tightly clustered customers. They’ve mastered technique so they work quickly without sacrificing quality. They’ve established pricing that reflects value. And they’ve created systems that generate steady, predictable income.

This comprehensive guide will teach you everything about building a profitable window cleaning business: startup costs and equipment decisions, mastering traditional and water-fed pole techniques, pricing strategies for maximum profit, building and maintaining your customer round, marketing approaches that generate steady bookings, and scaling from solo operation to team-based business.

Start smart. Build systematically. Grow strategically.

Why Window Cleaning Is Such a Brilliant Business Opportunity

Let’s start with the financial and strategic reasons this matters.

The Startup Costs Are Remarkably Low

Compare window cleaning to other service businesses:

Carpet cleaning: £600-£2,500 equipment investment
Gardening/landscaping: £1,000-£5,000 equipment
Pressure washing: £500-£2,000 equipment
Plumbing: £2,000-£8,000 tools and van
Window cleaning: £200-£500 initial investment

Basic window cleaning startup kit:

• Professional squeegee and applicator: £30-£60
• Extension pole: £40-£80
• Bucket and accessories: £20-£30
• Quality window cleaning solution: £15-£25
• Microfibre cloths: £10-£20
• Ladder (6-8ft step ladder initially): £40-£100
• Total: £155-£315

Water-fed pole system (if going this route):

• Entry-level system: £500-£1,500
• Mid-range professional: £2,000-£4,000
• High-end: £5,000-£10,000+

Most window cleaners start with traditional method (lower investment), then upgrade to water-fed pole once established.

The Business Model Is Perfect

Window cleaning offers ideal characteristics:

Recurring income: Most customers pay monthly or every 4-8 weeks. This creates predictable, steady revenue unlike one-off job businesses.

Low overheads:

• No shop or premises needed
• Minimal ongoing costs (solution, fuel)
• No staff required initially (scale later if desired)
• No expensive equipment maintenance

Cash flow friendly: Most customers pay cash or bank transfer immediately. No 30-day payment terms or chasing invoices.

Weather flexible: Can work in light rain (unlike many outdoor services). Occasional bad-weather days but generally consistent work opportunity.

Scalable: Start solo, add team members as business grows. Many successful window cleaners run 3-10 person operations.

Year-round demand: Unlike seasonal businesses, windows need cleaning consistently throughout year.

The Earnings Potential Is Excellent

Realistic income examples:

Part-time (2 days per week):

• 15-20 houses per day × 2 days = 30-40 houses weekly
• Average £6-£10 per house = £180-£400 weekly
• Annual (46 weeks): £8,280-£18,400
• After costs: £7,500-£17,000

Full-time (4-5 days per week):

• 20-25 houses per day × 5 days = 100-125 houses weekly
• Average £8 per house = £800-£1,000 weekly
• Annual: £36,800-£46,000
• After costs: £34,000-£43,000

Established business with assistant:

• 30-40 houses per day × 5 days = 150-200 weekly
• Revenue: £1,200-£1,600 weekly
• Assistant costs: £400-£500 weekly
• Your profit: £800-£1,100 weekly = £36,800-£50,600 annually

Many window cleaners earn £35,000-£55,000 annually once established with efficient rounds.

It’s Physically Sustainable

Unlike heavy manual labour, window cleaning is manageable long-term:

Physical demands:

• Moderate fitness required (ladder work, walking)
• Not excessively strenuous (compared to building, landscaping)
• Can continue well into later years (many window cleaners work into 60s-70s)
• Water-fed pole reduces physical strain further (ground-level work)

Many window cleaners appreciate that they can build sustainable business without destroying their bodies.

Customer Retention Is High

Once you gain customers, most stay for years:

Typical retention rates:

• 70-85% of customers stay year-over-year
• 10-15% churn (moving house, dissatisfaction, switching cleaners)
• 5-10% seasonal (summer-only customers)

This means: Acquire 100 customers, 70-85 become long-term recurring income. Each new customer acquired has multi-year value.

Build customer base of 150-200 regular houses, and you have stable, predictable business.

Essential Equipment and What Actually Works

Start with right equipment from beginning – false economy to buy cheap.

Traditional Method Equipment

Core tools:

Squeegee:

• Size: 10-14 inch most versatile
• Quality matters: Ettore, Unger, Moerman are professional brands (£15-£40)
• Spare rubber blades: £5-£15
• Cheap squeegees (£5) don’t work properly – false economy

Applicator (washer/sleeve):

• T-bar with washable sleeve or sponge
• Quality brands: £10-£25
• Multiple sleeves (rotate whilst washing): £8-£15

Extension poles:

• Start with 6-8ft telescopic pole: £40-£80
• Later add 12-18ft for higher windows: £80-£150
• Quality aluminum poles essential (cheap fibreglass breaks easily)

Bucket and accessories:

• Professional window cleaning bucket with tool holder: £20-£40
• Standard bucket adequate to start: £5-£10

Detailing cloths:

• Microfibre cloths (15-20): £10-£20
• For drying frames, sills, final touches

Cleaning solution:

• Professional window cleaning detergent (Unger, Fairy Liquid): £5-£15
• Avoid cheap supermarket products (leave residue)

Ladder (if doing traditional method):

• 6-8ft step ladder initially: £40-£100
• Eventually 3-section extension ladder: £80-£200
• Must be professional grade (domestic ladders inadequate)

Total traditional startup: £155-£315

Water-Fed Pole System

If going water-fed pole route:

Entry-level systems (£500-£1,500):

• Basic trolley system or backpack
• Small DI (deionisation) filter
• 25-30ft pole
• Brush heads
• Sufficient to start building round

Mid-range professional (£2,000-£4,000):

• Larger trolley system
• RO/DI (reverse osmosis + deionisation) filtration
• 35-40ft pole
• Better quality components
• Suitable for established business

High-end systems (£5,000-£10,000+):

• Van-mounted systems
• Large water tanks
• Multiple long poles
• Advanced filtration
• For large operations or commercial work

Water-fed pole advantages:

• Safer (ground-level work)
• Faster (once proficient)
• Reaches very high windows
• No ladders to carry
• Frames and sills cleaned simultaneously

Water-fed pole disadvantages:

• Higher initial investment
• Ongoing costs (DI resin replacement, filters)
• Learning curve (technique differs from traditional)
• Can’t use for interior cleaning
• Requires pure water (TDS 0-10)

Most new window cleaners start traditional, then transition to water-fed pole once income justifies investment.

Vehicle Considerations

Initially:

• Car adequate (ladder on roof rack)
• Estate car or small van ideal
• Keep equipment costs low whilst building round

Once established:

• Small van (Ford Transit Connect, Volkswagen Caddy)
• Allows secure equipment storage
• Professional appearance
• Van signage (marketing)
• Cost: £3,000-£15,000 depending on age

Don’t over-invest in vehicle initially – build customer base first.

The Pure Water Question

If using water-fed pole, water purity is critical:

TDS (Total Dissolved Solids) must be 0-10 ppm (parts per million).

Why: Dissolved minerals in tap water (calcium, magnesium) leave spots when water dries. Pure water dries completely clear.

Achieving pure water:

Deionisation (DI) only:

• Resin filters remove minerals
• Simple system
• Resin needs regular replacement (£20-£80 depending on water hardness)
• Adequate for soft water areas

Reverse Osmosis + Deionisation (RO/DI):

• RO membrane removes 95-98% of minerals
• DI resin polishes to 0 TDS
• Resin lasts much longer
• Better for hard water areas
• Higher initial cost but lower running costs

Fill from home or use spotless water stations (commercial pure water vending).

Insurance and Business Setup

Essential from day one:

Public liability insurance:

• £2-5 million coverage minimum
• Covers accidental damage (broken glass, etc.)
• Cost: £150-£350 annually
• Non-negotiable

Sole trader registration:

• Register with HMRC for self-assessment
• Free
• Required for tax purposes

Optional but beneficial:

Business bank account:

• Separates personal and business finances
• Professional appearance
• Easier accounting

Professional membership:

• Federation of Window Cleaners (FWC)
• Credibility and support
• Cost: £60-£100 annually

Mastering the Techniques

Equipment alone doesn’t create streak-free windows. Technique is everything.

Traditional Method: Squeegee Technique

The professional approach:

Basic squeegee stroke:

1. Wet window thoroughly with applicator (solution applied evenly)
2. Start at top corner
3. Pull squeegee across horizontally with overlapping stroke
4. Angle squeegee slightly (45-60 degrees)
5. Wipe blade with cloth after each stroke
6. Work down window in overlapping horizontal passes
7. Final vertical stroke on one side to catch drips
8. Detail edges with cloth

Critical points:

Consistent angle: Keep squeegee at same angle throughout stroke. Inconsistency causes streaks.

Adequate pressure: Too light leaves water. Too heavy causes juddering and streaks. Find balance.

Overlap strokes: Each pass should overlap previous by 1-2 inches. Gaps leave water lines.

Clean blade constantly: Dirty blade creates streaks. Wipe after every pass without exception.

Solution mixture: Too much soap creates residue and bubbles. Typical ratio: 1-2 drops detergent per litre water.

Practice makes perfect: First 50-100 windows will be challenging. By 200-300, you’ll be fast and consistently streak-free.

Water-Fed Pole Technique

The process:

Scrubbing phase:

1. Wet window with pure water flowing through pole
2. Scrub thoroughly with brush head (all directions)
3. Pay special attention to edges and corners
4. Ensure all dirt loosened

Rinsing phase: 5. Rinse from top down with continuous water flow 6. Multiple passes (water should run clear) 7. Finish with vertical strokes each side 8. Leave to dry naturally

Common mistakes:

Insufficient scrubbing: Rushing scrubbing phase leaves dirt that shows when dry.

Inadequate rinsing: Must rinse until water runs completely clear. Shortcutting this causes spots.

Water not pure enough: TDS above 10 causes spotting. Test water regularly.

Working too fast: Water-fed pole requires thoroughness. Speed comes with experience.

Initial learning curve is steeper than traditional method, but becomes faster once mastered.

Interior Window Cleaning

Always traditional method for interiors:

Process:

1. Lay cloth on sill (protect from drips)
2. Wet window with applicator (less solution than exterior)
3. Squeegee carefully (smaller strokes often work better)
4. Detail edges meticulously
5. Dry sill thoroughly
6. Buff glass if necessary

Interior cleaning usually takes longer per window (more care required, can’t afford drips on carpets/furniture).

Pricing for Maximum Profit

Get pricing right, and you’ll earn what you deserve whilst remaining competitive.

Understanding Market Rates 2025

National averages for residential window cleaning:

London and South East:

• Small house (10-15 windows): £8-£15 average £10-£12
• Medium house (16-25 windows): £12-£20 average £15-£18
• Large house (26-40 windows): £18-£35 average £25-£28

Major cities:

• Small: £6-£12 average £8-£10
• Medium: £10-£16 average £12-£14
• Large: £15-£28 average £20-£24

Other regions:

• Small: £5-£10 average £6-£8
• Medium: £8-£14 average £10-£12
• Large: £12-£22 average £16-£18

These are regular customer rates (monthly or every 4-8 weeks). One-off cleans command 20-30% premium.

Pricing Strategies That Work

Most profitable approach: Time-based pricing converted to per-house rate

Calculate your target:

• Desired hourly rate: £25-£35
• Average houses per hour: 3-4 (varies with method and experience)
• Per-house rate: £6.25-£11.67

Then adjust for:

• Property size (larger houses take longer)
• Access difficulty
• First clean vs. maintenance
• Region (London higher, elsewhere lower)

Examples:

Suburban area, medium houses:

• Target £30/hour
• Can clean 3.5 houses per hour
• Base rate: £8.50 per house
• Round to £8 or £9 for simplicity

Inner city, smaller properties:

• Target £30/hour
• Can clean 4-5 houses per hour
• Base rate: £6-£7.50
• Charge £6-£8

First Clean vs. Regular Price

First cleans take longer (establishing baseline, windows dirtier).

Two approaches:

Higher first clean price:

• Regular price: £10
• First clean: £15
• Transparent about difference

Or absorb first clean cost:

• Charge regular rate even for first clean
• Win customer loyalty
• Faster customer acquisition

Most established window cleaners use approach two (regular rate for first clean) as it removes barrier to new customers.

The Round System Pricing

Building efficient “round” requires strategic pricing:

Round = clustered customers visited on regular schedule

Pricing for round building:

Individual house pricing (non-round):

• £10-£12 per house
• Travel time between jobs
• Less efficient

Round pricing (tightly clustered):

• £7-£9 per house
• Minimal travel between properties
• Much more efficient

Lower per-house rate but higher hourly rate because you’re doing more houses per hour.

Example:

• Charge £12 individually = 3 houses/hour = £36/hour
• Charge £8 on round = 5 houses/hour = £40/hour

The round model is where real money is made.

Additional Services Pricing

Charge extra for:

First floor and above:

• Ground floor only: Base rate
• Ground + first floor: +30-50%
• Higher floors: +50-100% or quoted separately

Interior windows:

• Exterior only: Base rate
• Interior included: +30-50%

Conservatory:

• Walls: Included usually
• Roof: +£10-£30 depending on size

Frames and sills:

• Should be included in base rate
• Emphasise as value (some competitors charge extra)

UPVC cleaning:

• £5-£15 additional
• Required only occasionally

Building Your Round: The Foundation of Success

Profitable window cleaning business is built on efficient, reliable round.

What Is a “Round”?

A round is:

• Cluster of regular customers in specific geographic area
• Visited on predictable schedule (e.g., every 4, 6, or 8 weeks)
• Minimal travel time between properties
• Predictable, recurring income

Example round:

• 150 houses
• Average £8 per house = £1,200 per round
• Completed over 4-5 days
• Every 8 weeks
• Annual revenue: £7,800 from this round alone

Most successful window cleaners have 2-4 rounds in different areas, rotating through them on fixed schedules.

Starting from Scratch: Building First 50 Customers

Your initial focus:

Target one specific area: Don’t scatter geographically. Focus on 2-3 neighbouring streets initially.

Door-to-door canvassing (still works):

• Choose specific streets
• Knock doors early evening (5:30-7:30pm) or weekend
• Professional introduction: “Hi, I’m [name], professional window cleaner building a round in this street. I’m offering window cleaning at £[X] every [X] weeks. Could I leave you my details?”
• Leave flyer/business card
• Mark interested vs. not interested houses
• Return weekly initially to demonstrate reliability

Flyer distribution:

• Design simple flyer (professional but not expensive)
• Hand-deliver to 500-1,000 homes in target area
• Include: Services, price range, contact details, “Building regular round in your area”
• Expect 0.5-2% response rate (5-20 enquiries per 1,000 flyers)

Local online presence:

• Update Trader Street profile
• Local Facebook groups (many ban advertising but some allow)
• Nextdoor (neighbourhood app)
• Local online directories

Word of mouth:

• Ask happy customers for referrals
• Incentivise: “£5 off next clean if friend signs up”
• Most powerful long-term source

Initial pricing strategy: Price competitively (middle of market) to build base quickly. Don’t be cheapest (attracts wrong customers).

Target: 50 regular customers within 3-4 months.

Clustering: The Key to Profitability

Tight clustering makes all the difference:

Poor clustering:

• 8 customers spread across town
• 15-20 minutes travel between each
• Complete 8 houses in 6-7 hours
• Revenue: £64 (£8 per house)
• Hourly rate: £9-£11

Tight clustering:

• 8 customers in same/adjacent streets
• 2-3 minutes travel between each
• Complete 8 houses in 3 hours
• Revenue: £64
• Hourly rate: £21

Same customers, same revenue, dramatically different profit.

As you build round, prioritise customers in existing areas over scattered individual houses.

Schedule and Frequency Management

Establish clear schedule:

Most common frequencies:

• 4 weeks (higher maintenance, premium pricing, demanding)
• 6 weeks (good balance)
• 8 weeks (most common, easiest to manage)
• 12 weeks (occasional/seasonal customers)

Assign each customer to specific frequency, then build schedule accordingly.

Example schedule structure:

• Week 1-2: Complete Round A (150 houses)
• Week 3-4: Complete Round B (120 houses)
• Week 5-6: Complete Round C (130 houses)
• Week 7-8: Admin, maintenance, bad weather catch-up
• Repeat cycle

Communicate schedule clearly: “I clean your street every 8 weeks, typically on Wednesdays.”

Customers appreciate predictability.

Handling Difficult Customers

Occasionally you’ll encounter:

Chronic complainers:

• Never satisfied despite quality work
• Constant requests for free re-cleans
• Undervalue your service

Response: Politely end relationship. “I don’t think I’m the right fit for your needs. I’d recommend trying [other cleaner].”

Life’s too short for customers who don’t appreciate your work.

Non-payers:

• “Clean today, pay next time” repeatedly
• Always have excuse

Response: “I’ll return when previous invoices are settled.”

Stick to this. Don’t continue cleaning for non-payers.

Unreasonable requesters:

• Want additional services (clean gutters, wash car) for free
• Expect perfection in terrible weather

Response: Set boundaries politely but firmly. Charge appropriately for additional work.

High-quality customers more than compensate for difficult ones. Don’t tolerate poor treatment.

Marketing and Customer Acquisition

Build your round through strategic marketing.

Optimising Your Trader Street Profile

Profile must be professional and detailed:

Headline: “Professional Window Cleaning | Regular Rounds | Traditional & Water-Fed Pole”

Service description:

“Established professional window cleaner serving [your areas]. I provide reliable, high-quality window cleaning for residential properties on regular schedules.

What I offer:

• Regular window cleaning rounds (every 4, 6, or 8 weeks)
• Traditional method or water-fed pole (your preference)
• Exterior and interior cleaning
• Frames and sills included
• Conservatories
• UPVC frame cleaning

Method:

• [Traditional squeegee method / Water-fed pole pure water system]
• Professional-grade equipment
• Fully insured (public liability)
• Reliable and punctual

Current rounds: [Your service areas with schedule days] Example: “Clifton area: Every Wednesday, 8-week cycle”

Pricing: From £[X] for small houses Regular customers receive consistent service on reliable schedule

Experience:

• [X years] professional window cleaning
• [Number] regular customers
• Fully insured
• References available

I’m currently building/maintaining my round in [areas]. If you’d like to join my regular schedule, please get in touch.”

This positions you professionally and attracts customers seeking reliable regular service.

The Power of Consistency

Most powerful marketing: Being reliable.

Show up when you say you will.
Clean to consistent standard.
Communicate clearly.

This generates:

• Retention (customers stay for years)
• Referrals (satisfied customers recommend you)
• Reputation (you become “the window cleaner” in your area)

Reliability beats flashy marketing every time.

Seasonal Marketing

Adjust marketing to seasonal demand:

Spring: “Spring cleaning season – get your windows sparkling clean. Regular service available.”

Summer: “Summer sunshine shows every mark. Professional window cleaning makes the difference.”

Autumn: “Remove autumn grime before winter. Join my regular cleaning round.”

Winter: “Don’t let winter grime reduce your natural light. Professional window cleaning year-round.”

Building Referrals

Actively request referrals:

“I’m glad you’re happy with the service! I’m currently building my round in this area. If you have neighbours or friends who’d appreciate reliable window cleaning, I’d be grateful for recommendations.”

Incentivise if needed: “Refer a friend who joins the regular round, receive £5 off your next clean.”

Most window cleaning growth comes from referrals and reputation, not advertising.

Operations and Efficiency

Work smarter, not just harder.

Route Planning

Plan route for maximum efficiency:

Group properties by street: Complete entire street before moving to next.

Minimise backtracking: Plan logical geographic flow.

Start nearest your home: Reduce initial travel time.

Account for property specifics:

• Some houses locked gates (need customer home)
• Some prefer specific times
• Group accordingly

Use route planning tools: Simple spreadsheet or Google Maps with pins works initially. Dedicated route planning software available for larger operations.

Efficient routing increases income by reducing dead time.

Weather Management

British weather is challenging but manageable:

Can work in:

• Light rain (traditional method fine, water-fed pole preferred)
• Overcast conditions (actually ideal – glass dries slower)
• Light wind
• Cold but dry weather

Can’t work in:

• Heavy rain (visibility, safety)
• Strong wind (dangerous with ladders, water-fed pole difficult)
• Snow/ice (safety)
• Extreme heat (water dries too quickly, creates streaks)

Expect 15-25 weather cancellation days annually.

Plan accordingly:

• Schedule flexibility (reschedule rained-off jobs)
• Financial buffer (some weeks lower income)
• Customer communication (let them know about delays)

Time Management

Track your actual productivity:

Measure:

• Houses completed per hour
• Revenue per hour
• Time spent on admin/travel vs. working

Average productive window cleaner:

• 3-5 houses per hour (traditional method, varied properties)
• 4-6 houses per hour (traditional method, efficient round)
• 5-8 houses per hour (water-fed pole, efficient round)

If you’re significantly below these benchmarks, analyse why:

• Technical efficiency (are you fast enough?)
• Route efficiency (too much travel?)
• Customer quality (difficult properties slowing you down?)

Payment Collection

Cash flow is lifeblood:

Payment methods:

Traditional approach (still common):

• Clean windows
• Leave note requesting payment (if customer not home)
• Collect next visit or customer leaves cash in arranged location

Modern approach:

• Bank transfer (provide details via text message)
• Some cleaners use payment apps (PayPal, etc.)

Key principles:

Don’t clean repeatedly for non-payers: One missed payment, remind politely. Two missed payments, stop cleaning until settled.

Keep records: Simple spreadsheet tracking: Customer name, address, date cleaned, amount owed, date paid.

Consider monthly standing order for best customers: They set up automatic payment, you clean on schedule. Eliminates payment collection entirely.

Scaling Your Window Cleaning Business

Once established, strategic growth increases income substantially.

Adding Your First Employee

When to hire:

• You have more work than you can handle alone (turning away customers)
• You’re working maximum hours but demand continues
• You want to expand into new areas

Hiring strategy:

• Start with one helper/trainee
• Pay fairly (£12-£16 per hour typical)
• Train thoroughly to your standards
• Work alongside them initially
• Some window cleaners hire apprentices (government schemes available)

Economics of hiring:

• You complete 100 houses per week solo: £800 revenue, £750 profit
• You + helper complete 160 houses per week: £1,280 revenue, helper cost £480, your profit £750 (same profit but potential to grow further)

Key: Only hire when you have work to keep them busy. Underutilised employees destroy profit.

Building Multiple Rounds

Scale by geography:

Instead of one round: Build 2-4 separate rounds in different areas of your city.

Example business with 3 rounds:

• Round A: 150 houses, 8-week cycle = £1,200 per round
• Round B: 130 houses, 8-week cycle = £1,040 per round
• Round C: 140 houses, 6-week cycle = £1,120 per round
• Total per cycle: £3,360
• Annual: £21,840 (Round A), £17,940 (Round B), £26,880 (Round C) = £66,660

With assistant, two people can maintain 3-4 rounds efficiently.

Expanding into Commercial Work

Commercial window cleaning offers different opportunity:

Advantages:

• Larger contracts (offices, shops, schools)
• Less frequent but higher-value jobs
• Professional clients (reliable payment)
• Year-round necessity

Disadvantages:

• More competitive (larger companies involved)
• Often requires more extensive insurance
• May need specialist access equipment (cradles, platforms)
• Payment terms (30 days typical)

Many window cleaners build hybrid business:

• Residential rounds for steady base income
• Commercial contracts for higher-value work

The Financial Reality of Scaling

Solo window cleaner, efficient round:

• 120 houses weekly, £8 average
• Weekly revenue: £960
• Annual: £44,160
• After costs: £41,000
• After tax: ~£33,000 take-home

Window cleaner + one helper:

• 180 houses weekly, £8 average
• Weekly revenue: £1,440
• Helper cost: £480
• Your profit: £960 weekly = £44,160 annually
• After costs and tax: ~£34,000 take-home (plus you’re building asset – the business itself)

Window cleaner + two helpers, three rounds:

• 300 houses weekly, £8 average
• Weekly revenue: £2,400
• Helper costs: £960
• Your profit: £1,440 weekly = £66,240 annually
• After costs and tax: ~£47,000+ take-home

Scaling works if you maintain efficiency and quality.

Final Thoughts: The Opportunity Is Real

Window cleaning represents genuine opportunity for building profitable, sustainable business:

• Low startup costs (£200-£500 to begin)
• Recurring income model (customers pay monthly or every 4-8 weeks)
• Excellent earnings potential (£30,000-£55,000 annually realistic)
• Scalable business model (solo to multiple teams)
• Physical sustainability (manageable long-term)
• Constant year-round demand

Frequently Asked Questions

How much can I realistically earn from window cleaning?
Part-time (2 days weekly): £8,000-£18,000 annually. Full-time solo: £30,000-£45,000 annually. With helper: £35,000-£50,000 annually. Scaled with team: £50,000-£80,000+ potential. Earnings depend on round efficiency, pricing, and area.

Should I start with traditional method or water-fed pole?
Most window cleaners start traditional (lower investment £200-£500) to build initial customer base and income. Once established (50-100 customers, positive cash flow), invest in water-fed pole system (£1,500-£4,000). Traditional method perfectly adequate for building profitable business.

How long to build viable customer base?
Realistic timeline: 50-80 regular customers within 3-4 months of active marketing (door-knocking, flyers, local online presence). 120-150 customers within 6-9 months. Requires consistent effort building round in focused geographic area, not scattering across city.

What’s the best frequency for cleaning rounds?
8-week cycle most common and manageable (cleans houses 6-7 times annually). 6-week cycle generates more annual revenue per customer but requires tighter scheduling. 4-week cycle highest revenue but demanding. Start with 8-week until established.

How do I price competitively whilst making profit?
Calculate desired hourly rate (£25-£35), estimate houses per hour (3-5 depending on method and efficiency), derive per-house rate. Adjust for property size, region, and first-floor access. Most UK window cleaners charge £5-£15 per house depending on size and region, with efficient rounds generating £25-£40 per hour.

Do I need special certification or licence?
No legal certification required for residential window cleaning. Public liability insurance essential (£150-£350 annually). Register as sole trader with HMRC for tax purposes. Optional: Join Federation of Window Cleaners for professional credibility.

How do I handle non-paying customers?
One missed payment: Polite reminder. Two missed payments: Stop cleaning until account settled. Never continue cleaning for habitual non-payers – this isn’t charity. Most customers pay reliably; don’t tolerate the few who don’t.

Can I window clean part-time alongside other work?
Yes, many window cleaners start part-time (weekends or two weekdays). Build customer base gradually whilst maintaining other income. Transition to full-time once round generates sufficient income (typically 100-150 regular customers).

What weather prevents window cleaning?
Can work in light rain (water-fed pole ideal for this), overcast conditions, light wind, cold but dry weather. Cannot work safely in heavy rain, strong wind (especially with ladders), snow/ice, or extreme heat (creates streaks). Expect 15-25 weather cancellation days annually in UK.

How do I scale from solo to team operation?
Once you have more work than you can handle (turning away customers or working maximum hours), hire first helper (£12-£16 per hour). Ensure you have sufficient work to keep them busy. With helper, expand into new areas, building additional rounds. Many successful window cleaners run operations with 2-10 staff across multiple rounds.
