These figures assume a complete renovation including all major systems. Costs at the lower end reflect standard specifications, while higher figures include premium finishes and structural alterations. To sense-check these against per-area pricing, see our renovation cost per square metre guide, and for year-on-year movement in pricing review the UK renovation cost index 2026.
What a Full Renovation Typically Covers
- Complete kitchen installation with appliances
- New bathroom and en-suite if applicable
- Full electrical rewiring to current regulations
- New central heating system and boiler
- Replastering walls and ceilings throughout
- New flooring in all rooms

Factors That Increase Full Renovation Costs
- Structural work such as removing walls or underpinning
- Listed building or conservation area requirements
- Asbestos removal in properties built before 1999

- Damp treatment and tanking
- Roof repairs or replacement
- High-end fixtures, fittings, and materials

Timeline for Full House Renovation
A full house renovation typically takes 6-12 months to complete. Complex projects with structural work may take 12-18 months. Factor in 2-4 months for planning, design, and contractor selection before work begins. Delays are common, so build contingency into your timeline.
How to Budget for a Full Renovation
- Get detailed quotes from at least three contractors
- Add 15-25% contingency for unforeseen costs
- Budget for alternative accommodation during works
- Include costs for architects and project managers if needed
- Factor in VAT at 20% unless the property qualifies for reduced rate
- Consider staged payments to manage cash flow

How Module Costs Build a Full Estimate
RenoCost estimates are built bottom-up in three layers, so the relationship between per-area rates and a final project total is always traceable:
- 1Per square metre rate. The starting point is a regional £/m² figure for the chosen finish level — see the UK renovation cost per m² guide.
- 2Module-level cost. The £/m² rate is applied to each renovation module (kitchen, bathroom, electrics, plastering, etc.) using its own size, scope, and specification.
- 3Full project total. Module costs are summed and adjusted for postcode, property age, and condition to produce the final low / mid / high range — as shown on the full house renovation cost page.
Sources & Methodology
Pricing on this page is informed by a mix of public macro benchmarks and RenoCost's own datasets and assumptions, listed below. See the Method Glossary for definitions of the terms used.
- Office for National Statistics (ONS) — Construction StatisticsPublic macro benchmark. UK construction output, materials price indices, and labour cost data, used as a macro reference for inflation and trade-cost trends.
- BCIS (Building Cost Information Service)Public macro benchmark. BCIS is an independent UK construction cost data and benchmarking service. It was founded by RICS in 1961 and became independent from RICS in 2022. Listed here as external cost-planning context only. BCIS is not an input to RenoCost pricing and has no involvement with RenoCost.
- RICS Global Construction MonitorPublic macro benchmark. RICS quarterly survey of construction market sentiment, tender pricing and workload trends, including UK regional data.
- HomeOwners Alliance — UK renovation cost guidePublic macro benchmark. Independent UK consumer guidance on renovation budgeting and typical project costs.
- GOV.UK — Planning Portal & Building RegulationsOfficial guidance. Reference for planning permission, permitted development thresholds and Building Regulations approvals in England. Rules differ in Scotland, Wales and Northern Ireland.
- UK Renovation Cost Index 2026 (RenoCost)RenoCost's own current-year planning benchmarks, cross-referenced against the public macro sources above and used to calibrate pricing across the calculators and guides.

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.
