House Renovation Cost UK
How much does it cost to renovate a house in the UK?
A typical UK house renovation costs between £30,000 and £100,000 depending on property size, condition and scope. By property type, budgets commonly fall between £15,000 and £45,000 for a 1 to 2 bed flat, £25,000 and £65,000 for a 2 to 3 bed terraced house, £35,000 and £90,000 for a 3 to 4 bed semi-detached house, and £50,000 and £150,000 or more for a 4 to 5 bed detached house.
What this covers: Whole-house works including kitchen and bathroom refits, rewiring, plumbing and heating, plastering, decorating and flooring.
What changes the cost: Property size, building age, current condition, depth of the works, finish level and the regional labour market.
These are indicative planning ranges for 2026 UK pricing, not contractor quotations or confirmed final costs. Property size, condition, location and specification all affect the final figure.

How We Calculate Costs
RenoCost estimates are calculated from published UK cost benchmarks and RenoCost's documented per-module cost assumptions. The model adjusts these assumptions using the property characteristics, selected renovation scope, finish level and broad postcode-based pricing region, then presents a low, mid and high planning range.
- Published UK benchmarks — macro reference points for construction costs and materials and labour trends, used to sense-check RenoCost's own assumptions.
- RenoCost's per-module assumptions — cost and duration assumptions for each renovation module, reviewed and updated periodically by the RenoCost team.
- Estimate ranges — low, mid and high bands set to reflect the realistic spread between competitive and premium specifications, rather than a single fixed price.
Data confidence note
Completed calculator estimates are used to produce anonymous renovation-planning insights. They are not contractor quotations, invoices or confirmed final project costs. RenoCost estimates are intended for initial planning and budgeting. Property condition, specification, access, contractor availability and site-specific requirements can change the final cost. Always obtain detailed written quotations before committing to a project.
Regional adjustments are applied based on postcode area to reflect broad differences in local labour and material rates. See our Method Glossary for definitions of the terms used here.
