Small Kitchen Renovation Cost UK 2026: Real Figures for Tight Spaces
Quick Answer
Small kitchen renovation costs in the UK (under 8m²) range from £5,000–8,000 for a budget refit, £8,000–15,000 for a mid-specification renovation, and £15,000–25,000 for a high-specification finish. Key cost drivers in small kitchens: unit quality, whether plumbing is moved, electrical upgrades, extraction installation, and floor finish. Galley kitchens are typically at the lower end due to simpler layouts.
Small kitchens are one of the most common renovation jobs in UK properties — Victorian terraces, purpose-built flats and 1960s houses all tend to have compact kitchen spaces under 8m². And yet small doesn't mean cheap. A galley kitchen in a London flat can easily cost £12,000–£18,000 when you factor in the quality of units, trades access, and the cost of rerouting extraction in a tight space.
I've priced and managed hundreds of kitchen renovations over 32 years in the trade. The questions I hear most often are: what should this actually cost, and where does the money go? This guide answers both for small kitchens specifically — with real 2026 UK cost ranges split by budget tier, a breakdown by element, and notes on what changes the price most in compact spaces.
These figures cover the full renovation — strip-out, units, worktops, splashback, sink, tap, extraction, electrics, plumbing and flooring. Appliances are separate unless stated.
Small Kitchen Renovation Cost UK 2026: By Budget Tier
The three-tier breakdown below covers kitchens under 8m². All figures include fitting labour, basic plumbing connection (not rerouting), standard electrical work and a single appliance connection. Strip-out and disposal are included; structural changes and replastering are separate.
| Tier | Cost Range | What You Get |
|---|---|---|
| Budget | £5,000–£8,000 | Flat-pack or entry-level rigid units, laminate worktop, stainless sink, standard extractor, vinyl or laminate floor, basic tiling |
| Mid-spec | £8,000–£15,000 | Rigid units (Howdens, Magnet or similar), solid-surface or quartz worktop, undermount sink, integrated extractor or ceiling fan, LVT flooring, porcelain splashback tiles |
| High-spec | £15,000–£25,000 | Bespoke or handleless units, stone worktop, boiling water tap, under-cabinet lighting, heated floor, designer tiles, full appliance integration |
The jump from budget to mid-spec is largely driven by unit quality and worktop material. The jump from mid to high-spec is driven by bespoke joinery, stone worktops and appliance integration. In a small kitchen, the worktop length is limited — so the cost per linear metre of worktop has a smaller total impact than in a larger kitchen, but the unit quality is still the dominant cost driver.
What Drives Cost in a Small Kitchen
In a compact kitchen, the factors that move the price most are not always the ones homeowners expect. Understanding these helps you make smarter decisions about where to spend and where to save.
Unit Quality
Kitchen units are the single biggest variable. A full run of flat-pack units from a DIY retailer costs £800–£2,000 supply-only for a small kitchen. A mid-range rigid supply from a trade kitchen company runs £2,000–£5,000. A bespoke painted shaker or handleless range starts at £5,000 and can reach £15,000+ for a fully specified compact kitchen. The fitting cost is similar across tiers — it's the material that separates budget from premium.
Plumbing Changes
If the sink stays in the same position, plumbing costs are modest — typically £300–£700 for disconnection, reconnection and any minor adjustments. Move the sink, and you're looking at £500–£1,500 for the reroute depending on access. Move a gas hob, and you need a Gas Safe engineer: add £300–£800 on top of the plumber. In a small kitchen where every centimetre matters, even a 500mm shift in the sink position can trigger a significant replumbing job.
Electrics
Standard small kitchen electrical work — rewiring sockets, adding circuits for appliances, fitting under-cabinet lighting — typically costs £600–£1,500 for a competent electrician. If you're adding a new cooker circuit, induction hob circuit or underfloor heating circuit, allow an additional £300–£600 per circuit. All kitchen electrical work must be notified under Part P of the Building Regulations, which your electrician handles through their competent person scheme.
Extraction
Extraction is where small kitchens become disproportionately expensive. A standard canopy extractor ducted to an outside wall behind it is straightforward. A kitchen in the middle of a flat, or on an internal wall, requires a long duct run — potentially through multiple rooms — which can add £400–£1,200 in labour and materials, plus additional plastering and redecoration. Recirculating extractors avoid ducting entirely but require regular filter changes and don't remove moisture as effectively.
Floor Type
Vinyl sheet flooring is the cheapest option at £15–£30/m² installed. LVT (luxury vinyl tile) runs £35–£60/m² installed and is the most practical choice for a kitchen — waterproof, warm underfoot, easy to clean. Porcelain tile costs £50–£90/m² installed and is harder to fit in a small kitchen due to the cutting required. Heated floor adds £40–£80/m² for the mat plus an electrician to connect and set up the thermostat.
Galley Kitchen Renovation: Specific Considerations
A galley kitchen — one long, narrow room with units running down one or both walls — is common in Victorian terraces, purpose-built flats and rear extensions. The linear layout is efficient for fitting and for work triangle flow, but it creates some specific challenges.
Single-Run vs Double-Run
A single-run galley (units on one wall only) is simpler and cheaper. A double-run galley (units on both walls with a corridor in between) requires the aisle to be at least 900mm wide to meet Building Regulations for a working kitchen. In a galley under 1.8m wide, a double-run layout isn't practical — one wall has to be storage-only or left as clear wall. This limits the worktop and storage available and can push clients toward a different layout or a structural change.
Natural Light
Long, narrow galley kitchens often suffer from poor natural light, particularly if one end faces a wall or a dark corridor. Budget for under-cabinet LED strip lighting (£200–£500 supply and fit) and consider a higher-lumen ceiling light. In some cases, a rooflight or internal borrowed light window is the right solution — both of which require structural work and separate costs.
Extraction Runs
If the hob is at the end of the galley furthest from an exterior wall, the duct run will be long. Every bend in a duct run reduces extraction efficiency — there's a maximum equivalent duct run specified by the extractor manufacturer. Discuss duct routing with your kitchen fitter and electrician early, before units are ordered, to avoid discovering on site that the duct won't work as planned.
| Run Length | Budget Renovation | Mid-Spec | High-Spec |
|---|---|---|---|
| 2–2.5m run | £4,500–£6,500 | £7,000–£11,000 | £12,000–£18,000 |
| 3–3.5m run | £5,500–£8,000 | £9,000–£14,000 | £15,000–£22,000 |
| 4m+ run | £6,500–£10,000 | £11,000–£16,000 | £18,000–£26,000 |

Small Kitchen Renovation: Cost by Element
Here's how the budget breaks down across a typical small kitchen renovation. These are supply-and-fit ranges for each trade element.
| Element | Budget | Mid-Spec | High-Spec |
|---|---|---|---|
| Strip-out and disposal | £300–£600 | £300–£600 | £400–£800 |
| Kitchen units — supply and fit | £1,500–£3,000 | £3,000–£6,500 | £6,000–£14,000 |
| Worktops — supply and fit | £400–£800 | £800–£2,000 | £2,000–£4,500 |
| Sink and tap — supply and fit | £200–£400 | £400–£900 | £800–£2,500 |
| Extraction — supply, fit and duct | £250–£600 | £500–£1,200 | £1,000–£2,500 |
| Tiling — splashback | £200–£500 | £400–£900 | £700–£1,800 |
| Plumbing — connections and adjustments | £300–£700 | £400–£900 | £600–£1,500 |
| Electrics — circuits, sockets, lighting | £600–£1,000 | £800–£1,500 | £1,200–£2,500 |
| Flooring — supply and fit | £300–£600 | £500–£1,200 | £900–£2,500 |
| Decoration and finishing | £200–£500 | £300–£700 | £500–£1,200 |
| Total (excl. appliances) | £5,000–£8,000 | £8,000–£15,000 | £15,000–£25,000 |
Appliances are excluded from the above because the range is so large. A freestanding cooker and fridge-freezer can cost £400 from a clearance warehouse or £4,000+ from a premium brand. If you're integrating appliances, allow an additional £1,500–£4,000 for supply and the associated carpentry panels.
Regional Variation: London and the South East
Labour costs in London and the South East run 20–30% above UK averages. That mid-spec kitchen renovation costing £10,000 in the Midlands or North of England is likely to cost £12,000–£13,000 in London — sometimes more depending on the borough and the access constraints in the property. In a terraced house with no side return and a staircase directly from the front door, trade access charges alone can add several hundred pounds to a kitchen job.
Materials costs are broadly consistent across the UK — it's labour that accounts for the regional difference. If you're getting quotes in London and they seem high relative to national published figures, that's typically why.
Scotland, Wales and Northern Ireland have their own regional patterns — Northern Ireland typically runs below English averages, rural Scotland can run higher due to travel and trade availability. For any specific location, RenoCalc adjusts cost outputs based on regional labour rate data in the RenoCalc Spreadsheet.
Get Your Exact Small Kitchen Quote
The ranges in this guide give you a realistic starting budget. But the actual cost of your specific small kitchen renovation depends on your exact floor plan, your chosen spec, your location, and the current condition of the existing services. A builder's quote without a floor plan and a clear spec is just a number — it won't survive contact with the actual job.
RenoCalc was built specifically for this. Upload your floor plan — even a hand sketch — and RenoCalc reads the room dimensions, generates a room-by-room quote covering every element from units to extraction, and produces a full quote pack including cover letter, schedule of works and method statements. It takes around 3 minutes. The RenoCalc Spreadsheet behind the output contains 40,000+ live formulas and a current UK material price library updated for 2026 trade pricing.

How much does a small kitchen renovation cost in the UK?
A small kitchen renovation (under 8m²) in the UK costs £5,000–£8,000 at budget level, £8,000–£15,000 at mid-spec, and £15,000–£25,000 for high-spec finishes in 2026. The biggest variables are the quality of units, whether any plumbing or electrics are being moved, the extraction system and the floor finish. Appliances are typically separate from these figures.
What is the average cost of a galley kitchen renovation?
A galley kitchen renovation typically costs £6,000–£18,000 depending on the run length, unit quality, worktop material and whether any structural or plumbing changes are involved. The linear layout is efficient to fit but extraction can be challenging in a long, narrow space, and ducting costs vary significantly based on how far the duct needs to run.
Does moving the sink or hob increase the cost significantly?
Yes. Moving the sink requires rerouting waste and supply pipes, adding £500–£1,500 depending on access and distance. Moving a gas hob requires a Gas Safe engineer and adds £300–£800. If your kitchen layout stays broadly the same, costs are significantly lower — it's the changes to services that drive up small kitchen renovation costs most sharply.
How much does a small kitchen cost in London vs the rest of the UK?
In London and the South East, small kitchen renovation costs run 20–30% higher than UK averages. A mid-spec renovation costing £8,000–£15,000 nationally might cost £10,000–£19,500 in London. Materials are broadly the same — it's labour rates that differ. Factor this in from the start when budgeting in London.
Can RenoCalc quote a small kitchen renovation from a floor plan?
Yes. RenoCalc is designed to take a floor plan — including compact kitchens — and produce a full room-by-room quote including units, worktops, tiling, electrics, plumbing, extraction and flooring. The RenoCalc Spreadsheet contains 40,000+ live formulas and a current UK material price library. Upload your floor plan at renocalcapp.com/start and get a working estimate in around 3 minutes.
Build a Realistic Budget Before You Approach a Builder
Small kitchen renovations are easy to underestimate — the compact footprint makes people assume the job is simple, but the cost of quality units, trade services and extraction in a tight space adds up quickly. Use the figures in this guide to build your budget tier by tier, then get a specific quote from RenoCalc before inviting builders to tender.
Having a floor-plan-based estimate in hand before you start getting quotes means you can compare builder pricing against an independent baseline — and it prevents the situation where you're two weeks into a kitchen strip-out before anyone really knows what the job costs.
Questions About Small Kitchen Renovation Cost UK
Q: How much does a galley kitchen renovation cost in the UK?
A galley kitchen renovation in the UK costs £6,000–£18,000 depending on length, unit quality and worktop specification. The linear run is efficient to fit, which keeps labour costs slightly lower than L-shaped or U-shaped layouts. However, extraction ducting in a long narrow galley kitchen can add £500–£1,200 if it needs to run any distance to an external wall. Mid-spec galley kitchens with quality rigid units and quartz worktops typically cost £9,000–£14,000.
Q: What is a realistic budget for a kitchen renovation in a 1-bedroom flat?
A 1-bedroom flat kitchen is typically 4–7m² and costs £6,000–£16,000 to renovate depending on specification. Access in a flat can add cost — lift restrictions on delivery of units, parking charges for the kitchen fitter, and building management rules on working hours all contribute. Budget kitchens in flats lean toward the lower end; high-spec renovations in purpose-built London flats regularly exceed £20,000 once extraction and electrical upgrades are factored in.
Q: Does a kitchen renovation require Building Regulations approval?
A kitchen renovation that involves electrical work (new circuits, consumer unit changes) must comply with Part P of the Building Regulations — this means the work must be carried out by a registered competent person or notified to Building Control. Gas work (hob connections, gas supply alterations) must be carried out by a Gas Safe registered engineer. Like-for-like replacement of kitchen units without changing services does not require Building Regulations notification. See GOV.UK Building Regulations for details.
Q: How much do kitchen units cost for a small kitchen?
Kitchen unit costs for a small kitchen (under 8m²) range from £800–£2,000 supply-only for a flat-pack range, £2,000–£5,000 for trade rigid units (Howdens, Magnet, Symphony), and £5,000–£15,000+ for bespoke painted or handleless units. Supply costs are typically 40–55% of the total small kitchen renovation budget — fitting, worktops, tiling, plumbing and electrics make up the remainder.
Q: What are the best worktop options for a small kitchen budget?
Laminate worktops are the most budget-friendly at £80–£200 supply-only for a small kitchen run. Quartz offers durability and a mid-range aesthetic at £400–£900 supply-only. Natural stone (granite, marble) costs £600–£1,500+ supply-only and requires a professional template and fit. For small kitchens on a tight budget, a quartz off-cut or a high-quality laminate with an upstand provides excellent value. Solid wood worktops are an option at £300–£700 but require oiling and maintenance.
Q: Can I manage a small kitchen renovation as a project manager without a main contractor?
Yes — and many homeowners successfully manage small kitchen renovations directly with trades. You need to coordinate: demolition/strip-out, plumber (first-fix), electrician (first-fix), kitchen fitter, worktop template and fit, tiler, plumber (second-fix), electrician (second-fix), decorator. The risk is sequencing delays — if the tiler runs late, the kitchen fitter can't finish, and the plumber can't do second-fix. Having a detailed programme and clear dependencies between trades is essential.
