How Much Does It Cost to Renovate a House Room by Room?

There's no single answer to "how much does renovating a house cost" because a house is really a collection of very different jobs — a kitchen refit has almost nothing in common, cost-wise, with replastering a bedroom. The honest way to budget is room by room, using realistic UK ranges for each space, then adding contingency on top.

The figures below are broad, indicative UK ranges based on typical market pricing for a mid-range specification — always get 2-3 quotes for your actual property, since location, existing condition, and exactly what "renovate" means to you (cosmetic refresh vs strip-out-and-rebuild) all move the price significantly. See our renovation cost per square metre benchmark for a whole-house-level sanity check alongside these room figures.

Kitchen

Kitchens are usually the single most expensive room to renovate because of the combination of cabinetry, worktops, appliances, plumbing, and electrics all in one space. A straightforward like-for-like refit might run from around £8,000-£15,000, while a full kitchen renovation involving new layout, plumbing and electrical work often lands in the £15,000-£30,000+ range, and a large open-plan kitchen-diner with structural changes can go well beyond that.

Bathroom

A standard bathroom renovation (replacing suite, tiling, basic re-tiling of the room) typically runs from around £4,500-£8,000 for a straightforward refit, rising toward £8,000-£12,000+ for a larger bathroom, a wet room conversion, or where pipework needs significant rerouting. En-suites are usually cheaper in absolute terms due to their smaller footprint, but cost more per square metre because a bathroom's fixed costs (sanitaryware, waterproofing, tiling labour) don't shrink proportionally with room size.

Bedrooms and living rooms

A cosmetic refresh — new flooring, painting, some electrical work — for a typical bedroom or living room might run £1,500-£4,000 depending on size and finish. If the work extends to replastering, rewiring, or structural alterations (removing a wall, for example), costs rise substantially and are better estimated as their own project rather than a simple "room cost."

Replastering a room

If a room needs replastering as part of a wider renovation, or on its own, see our dedicated guide to replastering costs for a realistic per-room figure — it's one of the most commonly underestimated line items in a whole-house renovation budget.

Adding a home office or downstairs WC

Converting existing space into a home office is one of the cheaper "new room" additions since it typically doesn't require new plumbing — see our guide to home office costs. Adding a downstairs WC or utility room is more involved because it needs new plumbing and drainage connections; our downstairs WC and utility room cost guide covers what typically drives that price.

Period and Victorian properties

Renovating an older property, particularly Victorian or Edwardian housing stock, often costs more than an equivalent modern house because of solid walls, older electrics, potential damp issues, and the need to work sympathetically with original features. See our guide to renovating a period property for what specifically adds to the bill.

What moves these figures the most

• Specification level. The difference between a budget and a high-end finish in the same room can easily be 2-3x.
• Structural changes. Moving a wall, changing plumbing runs, or altering the roofline adds cost well beyond the "surface" renovation.
• Access and existing condition. A period property with restricted access or hidden problems (damp, old wiring, uneven floors) usually costs more than the headline figure suggests.
• Living in vs moving out. Staying in the property during work can slow progress and add cost — see our comparison of renovating while living in vs moving out.

Budgeting sensibly

Whatever your room-by-room total comes to, build in contingency — see our guide to contingency budgeting — and understand roughly how labour and materials costs actually break down, since that split affects where you can realistically save money without compromising quality. Before committing to a contractor, see our guide to getting renovation quotes and how real factors change your quote. Once work starts, our guide to payment stages explains what a normal payment structure looks like, and our renovation timeline guide sets realistic expectations for how long each type of project actually takes.

VAT considerations

Renovation work is usually subject to standard-rate VAT, though some circumstances (certain empty-property renovations, for example) can qualify for a reduced rate — see our guide to VAT on renovation work for what's genuinely worth checking before you budget.

Other rooms worth budgeting separately

A hallway or staircase refresh (flooring, painting, balustrade work) tends to sit toward the lower end of the whole-house budget, but is easy to forget when planning room by room since it's a shared space rather than a "room" in the usual sense — don't let it fall out of the total. A garage that isn't being converted into habitable space but is simply being tidied, insulated, or re-floored is a similarly easy line item to overlook.

A loft that isn't undergoing a full loft conversion (with dormer windows, staircase and building regulations sign-off) but is simply being boarded and lit for storage is a much smaller cost than a genuine loft conversion — the two are frequently confused when people first start budgeting, so it's worth being clear early on which one you actually mean.

A worked example

As an illustration only (not a quote), a household renovating a mid-terrace house might budget roughly: kitchen £18,000, bathroom £6,000, two bedrooms refreshed at £2,500 each, hallway and stairs £1,500, and a home office conversion £3,000 — a subtotal of around £33,500, before adding contingency (typically 10-20% depending on the property's age and condition) and confirming whether quotes are VAT-inclusive. This kind of room-by-room build-up, rather than a single vague "whole house renovation" figure, is generally the more reliable way to reach a realistic total.

Labour vs materials in each room

The labour-to-materials split varies considerably by room — a bathroom or kitchen typically has a higher materials proportion (sanitaryware, tiles, cabinetry, worktops) than a simple bedroom repaint, which is almost entirely labour. Understanding how labour and materials costs actually break down room by room helps identify where genuine savings are realistic (choosing a less expensive worktop, for example) versus where cutting corners on labour quality is usually a false economy.

Getting the sequencing right

If you're tackling several rooms as one overall project rather than genuinely one room at a time, sequencing matters: rooms with wet trades (bathrooms, kitchens) generally benefit from being scheduled so that dust from other work (plastering, flooring elsewhere) doesn't contaminate freshly tiled or painted surfaces. A realistic renovation timeline, agreed with your contractor room by room, is one of the most useful planning tools for keeping a multi-room project on budget as well as on schedule, since poor sequencing is a common, avoidable cause of rework and wasted materials.
