UK Renovation Cost Overview
Renovation costs in the UK vary enormously based on scope, location, property condition, and finish quality. As a broad guide, expect the following ranges per square metre:
Light Refresh
£400–£800
per m²
Standard Renovation
£700–£1,500
per m²
Full Refurbishment
£1,400–£3,000+
per m²
These ranges are indicative UK averages. Full refurbishment costs reflect strip-back projects involving new electrics, plumbing, heating, and structural work.
Major Cost Variables
Several factors significantly influence renovation costs. Understanding these helps you anticipate where your budget may stretch or where savings are possible:
- Property size and type: Larger properties cost more, but cost per square metre often decreases. Detached homes may need more external work; terraces have party wall considerations.
- Structural condition: Subsidence, damp, roof repairs, and foundation issues add substantial costs. Always budget for a structural survey.
- Systems replacement: Rewiring, replumbing, and heating upgrades are often necessary in older properties and can represent 15–25% of total costs.
- Timeline and access: Rushed timelines increase costs. Poor site access can add delivery and labour expenses.
Typical Renovation Timelines
- Cosmetic refresh (decorating, flooring): 2–6 weeks
- Kitchen or bathroom renovation: 3–8 weeks
- Standard whole-house renovation: 3–6 months
- Full strip-back refurbishment: 6–12 months
- Major structural work with extensions: 9–18 months
Allow extra time for planning permission if required, and build in contingency for delays caused by weather, material shortages, or unforeseen structural issues.

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.
