Small Kitchen Renovation Cost: What to Expect in a Compact Space

A small kitchen renovation (roughly under 8m²) in the UK typically costs £5,000–£15,000 for a straightforward like-for-like refit, or £15,000–£25,000+ if it includes plumbing/electrical changes, a new layout, or higher-spec units and worktops. The total is lower than a large kitchen simply because there's less floor area and fewer units, but the cost per square metre is often higher, since fixed costs like appliances, plumbing connections and labour don't scale down proportionally with size.

Why small kitchens don't cost proportionally less

A compact kitchen still needs a sink, hob, oven, extractor and full plumbing and electrical first fix — exactly the same fixed-cost items a larger kitchen needs. Labour costs for fitting are also similar regardless of size, since a fitter's day rate doesn't change much whether they're fitting 8 units or 15. This is why a small kitchen can end up costing a similar amount per square metre, or more, than a mid-sized one.

Where the money goes in a small kitchen

• Units and worktop: often 30–40% of the budget — choosing compact or slimline units (narrower depth base units, wall units that extend to the ceiling for storage) makes a real practical difference in a small space.
• Appliances: slimline or integrated appliances (a 45cm dishwasher instead of 60cm, a compact fridge) cost a similar amount to full-size versions but free up valuable floor space.
• Labour: broadly similar to a larger kitchen, since the same trades (plumber, electrician, fitter, decorator) are all needed regardless of room size.

Smart ways to save space and money

• Keep the existing layout where the sink, hob and plumbing already are — moving any of these in a small kitchen is proportionally more disruptive and expensive than in a larger room.
• Go floor-to-ceiling with wall units to maximise storage without extending the kitchen's footprint.
• Choose a single continuous run or L-shape rather than an island, which needs significant clearance space to be usable.
• Consider open shelving in place of some wall units — cheaper than cabinetry and can make a small room feel less enclosed.

Common mistakes in small kitchen renovations

The most common mistake is choosing units sized for a showroom display rather than the actual room — always work from precise measurements, and consider getting a fitter to survey before ordering cabinetry. Another frequent mistake is under-specifying extraction, which matters even more in a small, enclosed kitchen where cooking smells and moisture have less room to dissipate.

Appliance choices that make the biggest difference

In a small kitchen, appliance sizing has an outsized impact on how the space feels day to day. A 45cm dishwasher instead of the standard 60cm frees up a full cupboard of space; a slimline fridge-freezer or under-counter fridge with a separate small freezer elsewhere in the house can also help. These choices typically cost a similar amount to full-size equivalents, so the saving is entirely in usable space rather than budget.

A worked example

As a rough illustration: a 6m² galley kitchen with a straightforward like-for-like layout, mid-range units, laminate worktop and standard appliances might come to around £9,000–£12,000 fitted. The same footprint with a new layout (moving the sink), quartz worktop and integrated appliances could realistically reach £18,000–£22,000. Get a fitter to survey and quote your specific space rather than relying on any general figure, since access, existing wiring and plumbing condition all move the price.

Should you knock through to gain space?

If a small kitchen backs onto another room, removing or partially opening the dividing wall can be a more cost-effective way to gain usable space than trying to maximise storage within a fixed small footprint. This adds structural cost (see our guide to kitchen renovation costs for how this fits into an overall budget), but can transform how a small kitchen actually functions day to day, particularly for households that want a kitchen-diner rather than a separate, enclosed galley kitchen.

Getting the most from a small kitchen budget

Spend proportionally more on the things you touch and see every day — worktop, taps, handles — and proportionally less on elements that matter less in a small space, such as elaborate cabinet detailing that is barely visible in a compact room. A well-chosen, simple design in a small kitchen often reads as more considered than an overly busy one.
