Refurbishment cost estimator
A starting figure for a refurbishment from floor area and condition — for triage, not for offers you cannot walk back.
Rough order of cost only: 80m² at about £450/m² for a property in this condition. Get a builder to price it before you commit — this figure is for triage, not for offers you cannot walk back.

- A rate per square metre, applied flat across the property.
- No structural work, no extension, no change of layout.
This is a triage figure. It exists so a deal with no refurbishment number is not silently treated as needing no work.
This is one sum out of a whole deal
Inside the app the same engines run against real HM Land Registry sold prices, rank your buyers against the deal, and tell you what to do next — with the workings attached to every figure, exactly as they are here.
The demo runs on invented deals and real postcodes. No account, nothing saved.
Questions
How accurate is this?
Accurate enough to decide whether to drive to a viewing, and nowhere near accurate enough to offer on. Rates per square metre ignore everything that actually drives cost — the roof, the wiring, the drains, the thing behind the boarded-up wall.
Where do I find the floor area?
The EPC register publishes it for most UK homes, free. Failing that, the lease plan, the sale particulars, or a tape measure and ten minutes.
