How much does a kitchen renovation cost in London?

The short answer

A complete kitchen renovation in London can mean very different things. One quotation may cover cabinetry and fitting; another may include strip-out, structural work, plumbing, electrics, flooring, decoration, appliances and project coordination. A useful budget therefore begins with the complete scope rather than a price per cabinet.

For early planning, we use three broad investment bands. These are not quotations and they are not a substitute for a survey, but they help homeowners decide whether the intended finish and building work are aligned with the available investment.

Three realistic planning bands

A considered refresh at approximately £25,000–£40,000 may suit a sound room where the layout and main service positions remain largely unchanged. The investment can cover good-quality cabinetry, worktops, appliances, installation and selected finishing work, but it is unlikely to accommodate major structural change or fully bespoke joinery.

A full renovation at approximately £40,000–£70,000 allows more freedom with layout, services, lighting, flooring, upgraded appliances and a coordinated finish. This is often the relevant band for a long-term family kitchen where the whole room is being resolved rather than simply refaced.

A substantial transformation at approximately £95,000–£160,000 or more may include structural openings, an extension interface, highly bespoke cabinetry, complex stonework, premium appliances, specialist lighting and extensive preparation. Access, listed-building requirements and conservation constraints can increase professional and logistical costs.

A £25,000 minimum is a useful qualification for a managed London renovation, but the correct figure depends on what is actually included.

What should a complete quotation include?

A credible proposal should make the boundaries visible. It should state who is responsible for design information, surveys, protection, strip-out, waste, services, preparation, cabinetry, worktops, appliances, decorating, certification, snagging and aftercare.

Allowances should identify the assumed product or value. Exclusions should be as clear as inclusions. If structural work or hidden conditions cannot be fixed before opening up, the quotation should explain how those items will be assessed and approved.

• Pre-construction survey, scope and layout coordination
• Protection, strip-out and responsible waste removal
• Plumbing, electrical work and required certification
• Wall, floor and ceiling preparation
• Cabinetry, worktops, splashbacks and installation
• Appliances, lighting, flooring and decoration
• Project management, quality checks, snagging and handover
• VAT, provisional sums, exclusions and change-control process

The decisions that move the budget

Cabinetry is rarely the only major cost. Moving a sink, cooker or island changes plumbing, electrical and ventilation requirements. Removing a load-bearing wall introduces engineering, Building Regulations, temporary works, steel and making good. A side-return or rear extension changes the project from a room renovation into a building project.

Materials also change the total quickly. Factory-made units, semi-bespoke cabinetry and fully bespoke joinery have different design input, lead times and installation requirements. Natural stone, specialist finishes and premium appliances can be excellent choices, but they need to be coordinated early rather than added after the construction budget is fixed.

• Room size, layout change and number of tall or specialist units
• Cabinet construction, internal fittings and bespoke details
• Worktop material, thickness, edge profile and templating
• Appliance specification and electrical or ventilation demand
• Structural openings, floor levels and moved services
• Lighting design, flooring, decoration and adjoining-room work
• Parking, restricted access, lift protection and delivery windows

London-specific costs people overlook

Prime London homes often introduce costs that are not visible in a showroom quotation. Mansion blocks may require managing-agent approval, lift protection and limited working hours. Terraces can involve party-wall matters, constrained waste routes and neighbour coordination. Conservation areas and listed buildings may require specialist design or consent before work begins.

Existing buildings also contain uncertainty. Outdated wiring, inadequate water pressure, concealed leaks, uneven floors or historic alterations may only become fully visible after strip-out. A sensible contingency is not spare money to spend on upgrades; it protects the agreed result when genuine unknowns appear.

• Professional surveys, structural design and statutory approvals
• Party-wall advice where relevant
• Parking suspensions, permits and timed deliveries
• Building-management deposits and protection requirements
• Temporary kitchen arrangements or alternative accommodation
• A project-specific contingency for concealed conditions

How to compare kitchen renovation quotations

Put competing proposals into the same structure. Check the drawings and specification each contractor has priced, the products included, the assumptions about the existing building and the responsibilities left with you. A low total can simply mean that necessary work has not been included.

Ask how changes are recorded, who coordinates the trades, what evidence you receive at handover and how defects are handled. The best value is the route that gives you the required quality with the fewest unmanaged gaps—not automatically the lowest first number.

• Is the scope sufficiently detailed to compare like with like?
• Are VAT, design input and statutory fees clearly identified?
• Are product allowances realistic for the intended finish?
• Are structural, electrical and plumbing responsibilities explicit?
• Does the programme include procurement and decision deadlines?
• Are insurance, certification, warranty and aftercare explained?

Turn a budget into a considered plan

Begin with how the room needs to work, what must change and what can remain. Agree an investment range before developing a specification that cannot be afforded. Resolve the high-impact decisions—layout, structure, cabinetry level, worktops and appliances—before asking for a fixed proposal.

Our cost calculator can help establish an initial planning range. The next step is a home consultation and site assessment, where the assumptions can be tested against the actual property.
