Typical costs for a kitchen, bathroom, or full home

Indicative ranges for the most common project types we work on, with a sense of where the money actually goes. These are Spring 2026 prices for projects inside the M25; they refresh as the market moves.

A reminder: the right number for your project comes from the builder's quote after a site visit, not from this page. The ranges below help you decide whether the project is in the right ballpark.

How project costs are made up

Every project has three main cost buckets:

Labour — the builder, the trades, the time spent on site. Labour scales with how much work there is and how technical it is. Knocking through a wall, rerouting plumbing, or rewiring rooms all add labour-heavy days.
Materials — what you specify, fittings, finishes, appliances, sanitaryware, cabinetry. Materials scale almost entirely with the choices you make: same room, premium specification can be triple the materials bill of mid-range.
Site costs — scaffolding, skips, lead flashings, prelims, building control fees. These scale with project complexity and access, not directly with room size.

Two general rules:

Cost per room broadly tracks room size, but the curve isn't flat. A 30% bigger kitchen usually costs more like 50% more, because tile, flooring, and cabinet runs all expand.
Specification swings the number harder than size does. A small kitchen with bespoke joinery and premium appliances can cost more than a much larger kitchen done with mid-range standard cabinetry.

Bathroom

Indicative range: £10,000 to £25,000.

The lower end covers a like-for-like refresh: same layout, same plumbing locations, mid-range finishes. Labour is typically 50–60% of the total, materials around 30–40%, the rest is site costs.
The upper end covers a fuller renovation: new layout, structural changes, premium finishes, bespoke joinery. Labour share rises with structural work; materials share rises with specification.
Above £25,000 is common for larger bathrooms, multiple-room bathroom suites, or where a lot of structural or service rerouting is involved.

Kitchen

Indicative range: £20,000 to £80,000.

Kitchens vary more than bathrooms because cabinetry choice is the biggest single cost driver. Drivers worth knowing:

Cabinetry route. Standard ranges (Howdens, IKEA, similar) typically run £4,000–£12,000. Bespoke joinery typically runs £15,000–£40,000+ for the same room.
Worktops. Laminate from a few hundred pounds; engineered stone or quartz mid-thousands; natural stone or thick-format porcelain higher.
Appliances. Mid-range integrated suites typically £3,000–£6,000; premium suites £10,000+.
Structural work. Knocking through walls, moving services, lowering a kitchen-diner ceiling — each adds labour days and often building control sign-off.

For a like-for-like refresh in the same footprint, expect the lower end of the range. For a kitchen-diner created by removing a wall, with bespoke joinery and premium appliances, expect the upper end.

Full home

Indicative range: £100,000 to £400,000+.

Full-home projects are the most variable. The drivers:

How much of the home is touched. A whole-home refresh that leaves layouts alone is materially cheaper than one that reconfigures rooms.
Structural work. Knock-throughs, extensions, loft conversions, basement work — these dominate the budget when they're in scope.
Kitchen and bathroom count. Each room follows its own range above; multiply through.
Specification. The single biggest swing on a whole-home project.
External works. Re-roofing, new windows, façade work, landscaping.

Your planner will give you a tighter range once you've described the scope.

Why the ranges are wide

"A kitchen costs £X" isn't a useful sentence — the variables really do matter, and a tight number at this stage would set up the wrong expectation. The honest version: tell us what you want to do, and we'll give you a more specific view than what's on this page. The number you actually decide against is the builder's quote, after a site visit.

What this means for you

Use these ranges to sanity-check whether your budget is roughly right for the project you have in mind. If you're nowhere near the lower end, that's worth knowing now. If you're well above the upper end, your project may be more straightforward than you've assumed — or there may be options to explore.
