Official answer
How does mypropclear calculate a property valuation range?
The valuation starts with the property's own recorded HM Land Registry sale where available, updates it using the official regional UK House Price Index, then sense-checks it against recent nearby sales of the same property type. The range widens when evidence is older or sparse, and every input remains visible.
It is an evidence-led indication, not a mortgage valuation or surveyor's Red Book valuation.

What it's worth
Every sale HM Land Registry has recorded since 1995, adjusted for market movement with the official House Price Index, matched on property type, distance and how recently it sold — then shown as a low, most likely and high figure with the workings in full.

People also ask
Why is a property valuation shown as a range?
Official records do not describe every feature or condition change, so a range communicates evidence uncertainty more honestly than a single precise figure.
Does the valuation use asking prices?
The official baseline uses recorded completed sales and the UK House Price Index. Any separate premium listing or market data is identified by source and is not presented as a government record.
What can make the range less certain?
An old last sale, few same-type comparables, unusual transactions, missing floor area or major unrecorded alterations can all reduce confidence.
