£36,000 – £250,000Our calculator uses real UK 2026 contractor pricing and adjusts for your region, project size and finish level. The estimate gives you a realistic price range, but a fixed quote always requires a free in-home survey — material costs and site conditions vary.
Labour rates and material costs differ across the UK. London and the South East are typically 15–25% higher than the national average, the South West and Wales around 5% higher, the Midlands sit at the baseline, and the North, Scotland and Northern Ireland run roughly 10% lower. Our calculator applies these regional multipliers automatically using your postcode.
Kitchen and bathroom upgrades, loft conversions and extensions typically offer the best return on investment. A well-designed extension can add 10–20% to your home's value, while a loft conversion adds both space and value, often recouping 70–80% of the cost.
Timelines vary: a kitchen refit takes 1–3 weeks, a bathroom 1–2 weeks, a single-storey extension 8–12 weeks, a loft conversion 4–8 weeks, and a full house renovation 3–6 months. Your tradesperson will confirm a schedule after the survey.
Many extensions and loft conversions fall under Permitted Development, but larger builds, listed properties and conservation areas require planning permission. Electrical and gas work must be signed off by a certified engineer. Always check with your local authority before starting.
