Why Location Matters for Your Estimate
Labour costs vary significantly across the UK. A builder in Central London may charge £250-£350 per day, while rates in the North of England might be £150-£200 per day. Our calculator adjusts for these regional differences based on your postcode, giving you a more accurate estimate than generic national averages.
Getting a More Accurate Estimate
For the most accurate renovation cost estimate, use our calculator with your specific property details. Enter your postcode, property type, number of bedrooms, and building age. Then select exactly which renovation work you need, rather than a general full-house option. This personalised approach gives you a realistic budget range to work with.
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.
