How much is my house worth?
===========================

A practical guide to valuing a home in England using sold prices, floor area and the house price index, without paying for a surveyor first.

 PThe Percelio research team

 We build property valuations on HM Land Registry sold prices, EPC floor areas and the UK House Price Index. Reviewed June 2026.

The honest answer to "how much is my house worth" is: whatever a buyer will pay for it. But you can get very close to that number using public data, long before you call an agent or a surveyor.

Start with what sold nearby
---------------------------

The firmest evidence of value is what comparable homes actually sold for. HM Land Registry publishes the sold price of every completed sale in England and Wales. Look for homes on the same street or in the same postcode, of the same type, that sold recently.

Adjust for size
---------------

A four-bed semi is not worth the same as a two-bed flat that sold next door. The fairest way to compare is price per square metre. Floor areas are published in the EPC register for most homes, so you can work out a like-for-like rate and apply it to your own floor area.

Bring older sales up to date
----------------------------

A sale from three years ago happened in a different market. The UK House Price Index lets you adjust an older sale to today's prices for the right region and property type, so your comparison reflects the market now, not then.

Put it together
---------------

1. Gather comparable sold prices nearby.
2. Convert each to a price per square metre using its EPC floor area.
3. Index older sales to today with the UK House Price Index.
4. Apply the typical rate to your own floor area for an estimated value, with a sensible range around it.

That is exactly how a Percelio valuation works. You get the estimate, the range, and every comparable sale behind it.
