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.

Frequently Asked Questions

A typical UK house renovation costs between £30,000 and £100,000 depending on property size, condition, and scope of work. Basic refurbishment starts around £300 per m², while full renovations can reach £2,000+ per m².

Is it cheaper to renovate or buy a new house?

This depends on property prices in your area and the extent of work needed. Renovating can be cost-effective if you buy below market value and the structure is sound, but factor in living costs during renovation.

How long does a house renovation take?

A full house renovation typically takes 4-12 months depending on scope. Light refurbishments may take 6-12 weeks, while major structural work could extend to 12-18 months.

Do I need planning permission for a house renovation?

Most internal renovations fall under permitted development. However, structural changes, extensions, or work on listed buildings typically require planning permission. Check with your local authority.

What should I renovate first in a house?

Prioritise structural issues, roofing, and damp problems first. Then address electrics and plumbing before cosmetic work. This prevents having to redo finishes later.
