What this renovation cost calculator is for
Use this free UK renovation cost calculator when you are planning a flip, buy-to-let refurb or home improvement. Build a room-by-room budget for kitchens (cabinets and worktops), bathrooms and shower rooms, freshly painted bedrooms with new flooring, utility rooms with washer-dryer stacks, bar rooms with dark wood panelling, TV / cinema rooms, hallways and gardens — then add fees, VAT and a contingency buffer before you instruct trades.
Room-by-room works
Enter each room’s size and condition, then tick painting, flooring, plumbing, electrical (UK sockets & switches), tiling, appliances and more.
DIY vs trades labour
Mark jobs you will do yourself to cost materials only. Leave trades pricing on for certified plumbing, electrics and complex fit-outs.
VAT & contingency
Include UK VAT (or a custom rate) and a contingency percentage so the grand total reflects a realistic working budget.
Specialist rooms
Budget shower rooms, utility ironing space, bar fit-outs and cinema AV / soundproofing alongside standard kitchen and bathroom works.
How to estimate your renovation budget
- Open a room, enter the size in m² and choose the current condition.
- Tick the works you need (paint, flooring, cabinets, shower, utility appliances, bar fit-out, etc.).
- For each selected line, tick DIY if you will supply labour yourself — materials only are then counted.
- Add planning, building regs, architect and survey fees if known; set VAT and contingency.
- Read the live cost breakdown and cost per m² — totals update as you type. Get real quotes before committing.
Guide estimates based on typical UK residential rates. Not a contractor quote. VAT treatment can vary — check with your accountant for your project.

Renovation calculator FAQ
What does the renovation cost calculator include?
Room-by-room UK guide costs for kitchens, living rooms, bedrooms, bathrooms, shower rooms, utility rooms, hallways, bar rooms, cinema rooms and gardens — plus fees, VAT and contingency.
How do I use the DIY option?
After you tick a work item, mark DIY to cost materials only. Keep trades pricing for plumbing, electrical and certified work.
Are these renovation costs exact quotes?
No — they are typical UK estimates for planning. Always obtain independent contractor quotes for your postcode and specification.
Why add a contingency to a renovation budget?
Projects often uncover extras. A 10–15% contingency on the total is a common buffer for most residential refurbs.
