Kitchen size
Larger kitchens usually need more cabinetry, worktop length, flooring, wall finish and labour time.
Kitchen renovation cost calculator
Kitchen Renovation Cost Calculator UK
Estimate the cost of renovating a kitchen in the UK based on kitchen size, renovation type, cabinetry level, worktop choice, appliance changes, flooring, plastering, painting, plumbing complexity, electrics allowance, finish level and region.
Use this calculator for early budgeting, quote preparation and kitchen renovation scope planning. This is a planning estimate, not a fixed quote, kitchen design service, contractor assessment or DIY installation guide. A kitchen renovation quote can change after inspection, especially when the layout changes, services move, old units are removed or walls and floors need preparation.
What counts as a kitchen renovation?
A kitchen renovation is wider than replacing a single appliance or changing a tap. It may include removing old units, fitting new cabinetry, replacing worktops, updating appliances, making good walls, changing flooring, painting, tiling and coordinating plumbing or electrical allowances.
| Situation | Better description | Cost impact |
|---|---|---|
| Cabinet doors, handles or surfaces are refreshed | Basic kitchen refresh | Usually lower cost if the layout and services stay the same. |
| Old units and worktops are replaced in similar positions | Like-for-like kitchen replacement | Mid-range scope depending on cabinetry and worktop quality. |
| Cabinets, worktops, appliances and finishes are updated | Standard kitchen renovation | Typical full kitchen project with fitting, finish and preparation allowances. |
| Higher quality cabinets, surfaces and appliances are selected | Mid-range kitchen renovation | Higher material and fitting allowance. |
| Sink, appliances or layout move | Layout-change kitchen project | Plumbing, electrics, flooring and making good may increase. |
| Premium cabinetry and surfaces are selected | High-spec kitchen renovation | Higher material, labour and coordination allowance. |
Typical UK kitchen renovation cost ranges
These broad planning ranges help compare common kitchen renovation scopes. Use the calculator above for a more specific estimate based on kitchen size, cabinets, worktops, appliances, services, finishes and region.
| Kitchen project | Broad planning range | Best use |
|---|---|---|
| Basic kitchen refresh | £2,500–£7,500+ | Surface updates, selected replacements, limited disruption |
| Like-for-like kitchen replacement | £5,000–£14,000+ | Similar layout with new units and worktops |
| Standard kitchen renovation | £8,000–£20,000+ | Typical domestic kitchen replacement |
| Mid-range kitchen renovation | £12,000–£30,000+ | Better cabinetry, appliances, worktops and finishes |
| Layout-change kitchen renovation | £16,000–£42,000+ | Changed sink, appliances, services or layout |
| High-spec kitchen renovation | £25,000–£65,000+ | Premium cabinetry, worktops, appliances and finish detail |
These ranges are for planning only. A fixed kitchen renovation quote needs inspection, confirmed design, agreed materials, service checks and a clear schedule of inclusions.
What affects kitchen renovation cost?
The cost of a kitchen renovation depends on the physical size of the room, the quality of the selected products, how much preparation is needed and whether services need to move.
Renovation type
A basic refresh is much smaller than a full replacement or layout-change kitchen project.
Cabinetry level
Flat-pack units, standard fitted units, premium cabinetry and bespoke joinery sit in different cost bands.
Worktop choice
Laminate, timber, quartz, granite and premium surfaces can change the materials and fitting allowance.
Appliance package
Integrated, premium or relocated appliances can increase product cost and service coordination.
Plumbing complexity
Moving sinks, dishwashers or washing machines can add plumbing and waste route costs.
Electrics allowance
Socket changes, lighting changes and appliance circuit work can affect the final quote.
Surface preparation
Damaged walls, uneven floors, old tiling or poor plaster can increase making good before the new kitchen is finished.
Kitchen renovation, flooring, painting and plastering
Kitchen renovation often includes smaller interior finish scopes. Flooring may need to be replaced after old units are removed. Walls and ceilings may need making good before painting. Plastering can be needed where tiles, cabinets or old finishes have damaged the surface.
The Flooring Cost Calculator, Painting Cost Calculator and Plastering Cost Calculator are planned Interior Cost pages. Once published, they can be used alongside this kitchen calculator when those scopes need more detailed estimates.
Kitchen renovation and plumbing overlap
Kitchen renovation costs can overlap with plumbing when the sink, dishwasher, washing machine, waste pipe or water supply positions change. A like-for-like kitchen replacement may only need a small plumbing allowance, while a layout-change project can need a separate plumbing estimate.
Use the Kitchen Plumbing Cost Calculator when sink relocation, appliance connections or kitchen waste routes may affect the project.
View the Plumbing & Drainage Cost hub if the project also involves drainage, septic, bathroom plumbing or wider plumbing cost planning.
What may be included or excluded?
Kitchen renovation quotes vary by contractor, specification and agreed scope. Use this table to check what may sit inside or outside a kitchen renovation estimate.
| May be included | May be excluded |
|---|---|
| Removal of existing kitchen units where specified | Structural wall changes |
| Standard kitchen fitting labour | Kitchen design fees unless included |
| New cabinets and doors within the selected range | Regulated electrical work unless priced separately |
| Worktops within the selected range | Gas work unless specified by a suitable professional |
| Basic sink and appliance connection allowance | Major plumbing route changes unless included |
| Basic wall making good where selected | Hidden damp, rot, asbestos or unsafe materials |
| Flooring, painting or plastering where selected | Building control, permissions or specialist surveys |
| Waste handling where specified | Unexpected repairs found after removal |
When a kitchen renovation needs inspection before quoting
CostIntel can estimate a planning range, but a kitchen renovation quote needs inspection when the real scope depends on layout, services, existing units, wall condition, floor condition or final specification.
The layout is changing
Moving the sink, appliances or services can change plumbing, electrical and fitting costs.
Old units need removing first
Hidden damage, poor walls, uneven floors or old pipework may only be visible after removal.
Floors are uneven
Flooring and cabinet fitting can be affected by subfloor condition.
Walls or ceilings need repair
Old tiles, cabinets, cracks or poor plaster can increase preparation and decorating costs.
Electrics are not confirmed
Socket, lighting and appliance requirements may need assessment before the quote is fixed.
Premium finishes are selected
Stone worktops, bespoke cabinetry and integrated appliances usually need a clearer specification before pricing.
How this kitchen renovation estimate is calculated
The calculator starts with a base range for the selected kitchen renovation type, then adjusts the estimate using kitchen size, cabinetry level, worktop choice, appliance changes, plumbing complexity, electrical allowance, flooring, surface preparation, finish level and region.
This approach is designed for early project planning. A fixed quote can change after inspection, especially when the layout changes, existing units are removed, services need moving or the condition of floors, walls and ceilings is unclear.

How much does a kitchen renovation cost in the UK?
A basic kitchen refresh may start from a few thousand pounds, while a standard kitchen renovation can often sit in the five-figure range. Mid-range, layout-change and high-spec kitchen renovations can cost much more depending on cabinetry, worktops, appliances, services, flooring, preparation and region. Use the calculator for a more specific planning range.
What is the difference between a kitchen refresh and a kitchen renovation?
A kitchen refresh usually updates selected visible elements, such as doors, handles, surfaces or decoration. A kitchen renovation is wider and may include new cabinets, worktops, appliances, fitting, flooring, plastering, painting and service changes.
Does this calculator include kitchen fitting?
Yes, the estimate can include a kitchen fitting allowance within the selected renovation type. The exact scope depends on the chosen cabinetry level, worktop type, appliance changes, finish level and whether preparation or service changes are included.
Does this calculator include plumbing?
It includes a planning allowance for plumbing complexity, but it is not a plumbing quote. If the sink, dishwasher, washing machine or waste route is moving, use the Kitchen Plumbing Cost Calculator alongside this estimate.
Does this calculator include electrical work?
It includes an electrical allowance where selected, but it does not provide electrical advice or a fixed electrical quote. Electrical work should be assessed and priced by a suitable professional.
Why do kitchen renovation quotes vary so much?
Kitchen quotes vary because the scope can include cabinetry, worktops, appliances, plumbing, electrics, flooring, plastering, painting, removal work, waste handling and finish quality. Hidden issues can also appear after old units are removed.
When should I get an inspection before relying on the estimate?
Inspection is needed when the layout is changing, services may move, old units have not been removed, floors are uneven, walls are damaged, moisture is suspected or the final kitchen specification is not confirmed.
Is this a fixed kitchen renovation quote?
No. CostIntel provides planning estimates for early budgeting and quote preparation. A fixed quote needs inspection, confirmed scope, agreed materials and contractor assessment.
Does this calculator give DIY kitchen installation advice?
No. This calculator is only for kitchen renovation cost planning. It does not provide DIY installation instructions, regulated trade guidance, design advice, structural advice or professional installation advice.
