Not another cost-per-m2 guess
Most refurb calculators give you a single cost-per-square-metre figure and call it a day. The problem is that location alone can swing costs by over 35%. Specification, delivery method, and market conditions change the rest. A generic number is a dangerous number.
Refurb Calculator is different. Our pricing comes from the same live procurement data that Help Build's estimating team uses to cost and deliver real refurbishment projects every week. Materials, labour rates, and allowances are updated continuously based on actual supplier quotes and contractor costs across the UK.
The result: estimates you can negotiate with, borrow against, and build from.

Built by estimators and construction professionals, not a IT Company
Refurb Calculator was built by Help Build, a construction estimating and project management firm with 18 years in the industry. We cost and deliver refurbishment projects every week, and the same pricing data our team uses on live jobs is what powers your estimates.
We are not a tech startup guessing at construction costs. We are estimators who built a tool to solve our clients' biggest problem: getting reliable numbers fast enough to compete.

How developers use Refurb Calculator with their lender
Questions developers ask before signing up
Our pricing is built from the same live procurement data that Help Build's estimating team uses to cost and deliver real refurbishment projects. Materials, labour rates, and allowances are updated continuously based on actual supplier quotes and contractor costs. Estimates are designed for negotiation, lending applications, and contractor briefings.
Yes. The full calculator factors in regional cost variance, which can be over 35% between the cheapest and most expensive parts of the UK. Your estimate reflects where your property actually is, not a national average.
Residential refurbishment works including strip-out, plastering, kitchens, bathrooms, electrical, plumbing, flooring, joinery, roofing, and external works. Designed for flips, HMO conversions, buy-to-let refurbs, and self-build renovations. It does not currently cover commercial fit-outs or new builds.
Free calculators typically use a single cost-per-square-metre figure with static, outdated pricing. ChatGPT is not powered by real trades, real materials, or real construction experience. Refurb Calculator gives you a line-by-line breakdown by work type, using up-to-date regional trade material and labour rates, and exports a professional schedule of works that contractors and lenders will accept.
Yes, a card is required at sign-up, but you will not be charged during the 7-day trial. You get full access to unlimited estimates, PDF exports, and the project dashboard. Cancel anytime before the trial ends and you pay nothing. No contract, no lock-in.
Yes. It works in your browser on phones and tablets, so you can build your estimate while walking through the property. Most users finish in about 20 minutes on site.
Continuously. Help Build costs and delivers refurbishment projects every week. Material prices, labour rates, and allowances are updated as they change in the real market, not on a yearly schedule.
