Walk into any kitchen showroom or start researching your kitchen renovation online, and you’ll quickly encounter a confusing array of professionals: kitchen fitters, joiners, carpenters, cabinet makers, and general builders all claiming they can handle your project. Hiring the wrong specialist doesn’t just cost money—it creates delays, substandard results, and the frustration of coordinating multiple tradespeople who should have been part of the original plan.
This comprehensive guide cuts through the confusion, explaining exactly what each trade does, when you need them, what they’ll actually charge in 2025, and how to avoid the costly mistakes that turn dream kitchens into renovation nightmares.
The Core Distinction: Making vs Fitting vs Building
Before diving into kitchen-specific roles, understanding the fundamental differences between these woodworking trades prevents confusion and costly hiring mistakes.
Joiners: The Workshop Craftspeople
What they do: Joiners construct items by joining pieces of wood together, typically without metal fasteners, using techniques like dovetail joints, tongue-and-groove, and mortise-and-tenon connections. Their work happens off-site in a workshop where they have access to large, stationary machinery.
What they make for kitchens:
- Bespoke kitchen cabinets and units
- Custom drawer boxes and internals
- Handcrafted doors and drawer fronts
- Purpose-built pantry units
- Specialist storage solutions for awkward spaces
- Solid wood worktops (cutting and jointing)
- Made-to-measure shelving systems
Tools and location: Heavy-duty workshop equipment including table saws, thickness planers, mortising machines, lathes, and sanding stations. Work is done off-site before delivery to your property.
When you need a joiner for your kitchen:
- Custom or bespoke kitchens requiring unique dimensions
- Period property kitchens needing traditional joinery techniques
- Awkward or non-standard spaces demanding made-to-measure solutions
- High-end projects where craftsmanship and quality materials justify the premium
- Repairing or replicating antique or heritage kitchen elements
Typical costs 2025: £200-400 per day, or £20-£40 per hour for standard work. Bespoke joinery projects often quoted as fixed prices based on complexity, ranging from £3,000-£15,000+ for complete custom kitchen cabinetry.
What joiners typically don’t do: Install their own creations on-site (though some do), plumbing, electrical work, tiling, or plastering. They build components; others fit them.
Carpenters: The On-Site Installers
What they do: Carpenters work on-site, installing the items that joiners have created, along with constructing larger structural elements. They use portable tools that can be moved between locations.
Carpentry work in kitchen projects includes:
- Installing pre-made kitchen units and cabinets
- Fitting doors and drawer fronts
- Installing architraves and skirting boards
- Building partition walls or stud walls
- Installing door frames and hanging doors
- Fitting cornice and pelmet
- Installing kick-boards and plinths
- First-fix work (structural framing if extensions involved)
- Second-fix finishing (detailed trim work)
Tools and location: Portable equipment like circular saws, nail guns, power drills, routers, and hand tools. Work happens on your property.
When you need a carpenter for your kitchen:
- Installing flat-pack or pre-assembled kitchen units
- Hanging kitchen doors and fitting hardware
- Building boxing-in for pipes and services
- Installing skirting, architraves, and trim work
- Constructing framework for kitchen extensions
- Fitting worktops (though specialists often handle stone)
Typical costs 2025: £150-£240 per day, or £25-£35 per hour.
What carpenters typically don’t do: Create bespoke joinery from scratch (though some have joinery skills), plumbing connections, electrical installations, or gas work. They install and construct; they don’t design custom pieces or handle services.
Kitchen Fitters: The Specialists
What they do: Kitchen fitters are specialists who focus exclusively on kitchen installation. Think of them as carpenters who’ve specialised entirely in kitchens, developing expertise in the specific challenges and requirements of kitchen projects.
A kitchen fitter’s scope includes:
- Removing existing kitchens (including disconnecting services carefully for others to reconnect)
- Building and installing kitchen units (flat-pack or pre-assembled)
- Fitting kitchen doors, drawer fronts, and hardware
- Installing worktops and joining sections
- Fitting sinks, taps, and waste pipes (physical installation, not mains connection)
- Installing appliance housings
- Fitting kick-boards, plinths, cornices, and pelmets
- Positioning appliances (physical placement)
- Making adjustments for uneven walls and floors
- Often: basic tiling (splashbacks)
- Sometimes: plastering and decorating
- Sometimes: floor laying
What kitchen fitters definitely DON’T do (the “dry fit” limitation):
- Connect plumbing to mains water supply
- Connect electrics to consumer units or add circuits
- Connect gas appliances
- Issue Gas Safe certificates
- Certify electrical work
- Sign off building regulations
However, many experienced kitchen fitters are also qualified as:
- Plumbers (can do full plumbing work)
- Part P electricians (can do electrical installations)
- Gas Safe registered (can connect gas appliances)
- Multi-skilled tradespeople (can tile professionally)
This multi-skilled capability is what separates experienced, premium kitchen fitters from basic installers. When hiring a kitchen fitter, clarify exactly which additional qualifications they hold—this determines whether you need to hire separate tradespeople or whether your fitter genuinely can handle everything.
Typical costs 2025:
- Day rate: £250-£350 (average £300)
- London and Southeast: £350-£500 per day
- Hourly rate: £30-£40 per hour
- Complete installation labour only (average 14 sqm kitchen): £3,500
- Small kitchen installation: £1,500-£2,200
- Large kitchen installation: £4,600-£6,000+
What separates good kitchen fitters from poor ones:
- Experience with multiple kitchen ranges (not just one supplier)
- Problem-solving skills for uneven floors, walls, and services
- Knowledge of building regulations and kitchen-specific requirements
- Ability to work around existing structures and services
- Understanding of proper ventilation requirements
- Professional approach to minimising disruption and mess
- Clear communication about what they can and cannot do

DIY warning: Kitchen installation looks simpler than it is. Uneven floors, out-of-square walls, and service locations create challenges that experienced fitters handle routinely but can stop DIY projects cold. Poor installation voids warranties on expensive units. Realistically assess your capabilities before committing.
Hiring the Right Kitchen Fitter: The Critical Questions
Not all kitchen fitters are created equal. These questions separate professionals from cowboys:
Qualification and Experience Questions
“What qualifications and certifications do you hold?”
- Look for: NVQ in Kitchen Fitting, City & Guilds Carpentry and Joinery, membership of KBSA or BiKBBI
- Bonus: Part P electrical certification, plumbing qualifications, Gas Safe registration
- Red flag: No formal qualifications, vague answers, or claims they “don’t need certificates”
“How long have you been fitting kitchens, and how many do you complete per year?”
- Good answer: 5+ years experience, 15-30 kitchens annually
- Concerns: Less than 2 years experience, very low or impossibly high numbers (quality vs quantity)
“Which kitchen brands and types have you worked with?”
- Look for: Experience with multiple suppliers and both flat-pack and rigid units
- Red flag: Only ever fitted one brand or type (limited problem-solving experience)
“Can you provide references from recent kitchen installations?”
- Essential: At least 3 verifiable references from the past 12 months
- Follow up: Actually contact these references and ask specific questions
- Warning sign: Reluctance to provide references or only very old ones
Scope and Service Questions
“What exactly is included in your quote, and what isn’t?”
- Should specify: Unit assembly and installation, worktop fitting, appliance housing, sink positioning (but not connecting), tiling scope if included
- Should explicitly state what’s NOT included: Electrical connections, plumbing connections, gas work (unless separately qualified)
- Red flag: Vague “complete kitchen fitting” without itemisation
“Do you have your own Part P electrical certification and plumbing qualifications?”
- Best case: Yes to both (genuinely multi-skilled fitter)
- Acceptable: No, but works with trusted electricians/plumbers (coordination arranged)
- Warning: Claims they can “sort out” electrical/plumbing without proper qualifications
“Will you handle removal and disposal of the existing kitchen?”
- Standard: Yes, usually included or small additional cost (£200-£500)
- Check: How they’ll dispose of it (skip hire, council waste, recycling)
- Clarify: Whether skip hire is in the quote or an extra cost
“How do you handle problems like uneven floors or out-of-square walls?”
- Good answer: Specific techniques they use (scribing, levelling compounds, adjustment methods)
- Poor answer: “That won’t be a problem” without acknowledging reality (almost all kitchens have these challenges)
Project Management Questions
“What’s your realistic timeline for this project?”
- Typical: 1-2 weeks for standard kitchen replacement
- Longer if: Structural changes, extensive tiling, complex worktop installations
- Red flag: Promises impossibly quick completion or can’t provide timeline
“Will you be doing the work yourself or using subcontractors?”
- Either is fine, but you need to know who’ll actually be in your home
- If subcontractors: Ask about their qualifications and experience
- Coordination: Who manages the electrician/plumber—you or the fitter?
“How do you handle unexpected issues or required variations?”
- Look for: Clear variation process, written quotes for changes, consultation before proceeding
- Warning: “We’ll sort it” without discussing cost implications
“What insurance do you carry?”
- Essential: Public Liability Insurance (minimum £2 million, preferably £5 million)
- Verify: Ask to see current insurance certificates
- Protection: Ensures you’re covered if damage occurs during installation
Cost and Payment Questions
“Can you provide a detailed written quote?”
- Must include: Labour breakdown, materials if supplying, timeline, payment schedule
- Warning: Only verbal quotes or single-figure estimates
“What’s your payment schedule?”
- Standard: Small deposit (10-15%), stage payments tied to milestones, retention after completion
- Red flag: Large upfront payment (over 25%), full payment before completion, cash-only demands
“What warranties do you offer on your work?”
- Typical: 12 months for workmanship, manufacturer warranties for materials
- Concerns: No warranty offered, very short warranty period
“What happens if I’m not satisfied with any aspect of the work?”
- Look for: Clear snagging process, willingness to address issues, professional complaints handling
- Warning: Defensive attitude, no process for addressing concerns
Red Flags That Demand Walking Away
Some warning signs indicate problematic fitters. Protect yourself by rejecting anyone who:
Immediate deal-breakers:
- Requests large upfront payments (over 25% deposit)
- Insists on cash-only transactions
- Cannot provide proof of insurance
- Has no verifiable references or portfolio
- Offers to handle electrical/gas work without proper certification
- Provides only verbal quotes with no written documentation
- Pressures you to sign immediately or claims limited-time pricing
- Cannot provide company registration details or business address
- Uses generic unmarked vehicles with no business branding
- Offers suspiciously low prices significantly below other quotes
- Claims electrical/plumbing work “doesn’t need certification”
- Suggests avoiding building control when it’s clearly required
Serious concerns requiring extra scrutiny:
- Very recent company registration (within 6 months)
- Only contactable by mobile phone
- No established online presence or reviews
- Unable to explain their working process clearly
- Vague answers about qualifications and experience
- Reluctance to let you speak with previous clients
- Cannot explain how they handle specific challenges
- Dismissive of your questions or concerns
- Poor communication or unprofessional behaviour during quote stage
The Cost of Getting It Wrong: Real Consequences
Hiring the wrong kitchen fitter or the wrong combination of trades creates problems far beyond simple annoyance:
Financial consequences:
- Paying twice (once for poor work, again to fix it): £5,000-£15,000+
- Damaged units requiring replacement: £2,000-£10,000
- Water damage from poor plumbing: £3,000-£20,000
- Electrical fires from uncertified work: Property loss, insurance invalidation
- Unable to sell property due to uncertified work: Requires retrospective certification or reinstallation
Legal and insurance issues:
- Uncertified electrical work invalidates home insurance
- Uncertified gas work is illegal and extremely dangerous
- Building regulation non-compliance prevents property sales
- Cannot remortgage with non-compliant installations
- Potential prosecution for illegal gas work
Time and stress:
- Extended project timelines while finding replacements: Weeks to months
- Living without a functioning kitchen: Stress, expense, relationship strain
- Legal disputes with rogue traders: Time, cost, emotional toll
- Coordinating multiple replacement tradespeople: Project management burden
Final Thoughts: Investing in the Right Professionals
Your kitchen represents one of your home’s most expensive rooms and a space you use multiple times daily. The cost difference between hiring proper professionals versus cutting corners is measured in thousands. The quality difference is measured in decades.
Key principles for success:
- Understand who does what: Don’t expect kitchen fitters to be electricians or joiners to be plumbers
- Verify qualifications: Never take claims at face value; always check certifications
- Get multiple quotes: Three written quotes provide realistic cost expectations
- Check references: Actually contact previous clients and ask specific questions
- Insist on proper certification: Especially for electrical and gas work
- Use written contracts: Protect yourself with detailed, signed agreements
- Structure payments properly: Never pay in full upfront; tie payments to milestones
- Coordinate trades carefully: Ensure your kitchen fitter, electrician, plumber, and gas engineer know who’s doing what and when
- Allow realistic timelines: Quality work takes time; rushed jobs create problems
- Budget for the proper professionals: Trying to save £500 by skipping proper electricians can cost £10,000 when things go wrong
The right kitchen fitter, supported by qualified electricians, plumbers, and other specialists, transforms your kitchen renovation from a stressful ordeal into a smooth process delivering results you’ll enjoy for decades. The wrong combination creates an expensive nightmare you’ll regret immediately and struggle to rectify for years.
Choose wisely. Your kitchen deserves it.
