How we work out your gain
It's refreshingly simple. We take what you paid, then uplift it by how much the average price in your local area has changed since — using the HM Land Registry House Price Index. The difference between that and your purchase price is your estimated gain.
Because it tracks your actual area, it reflects real local market movement, not a national headline figure.
Why your area matters so much
House prices move very differently around the country — a home in one region might have doubled over a period while another barely moved. Using your local authority's price change, rather than a UK average, gives a far more honest picture of your own gain.
What you can do with the gain
Your increase in value isn't just a nice number — it's equity. A higher value against your outstanding mortgage means a lower loan-to-value, which can unlock better remortgage rates. It also matters if you're thinking about moving up, releasing equity, or simply tracking your wealth.
Track it for free. Pop your email into the tool above and we'll send a free update when prices in your area move — no account, no estate-agent calls, no catch.
Frequently asked questions
How do I find out how much my house has increased in value?
Take what you paid and adjust it by how much prices have moved in your area since — which the tool above does instantly from your postcode, using official Land Registry data.
Has my house gone up or down in value?
The estimate reflects both. If average prices in your area have fallen since you bought, it'll show a lower figure than you paid; if they've risen, you'll see the gain.

General information only, not a formal valuation. Estimates use area averages and can't see your specific home — for a precise figure use a RICS surveyor or local agent.
