Whether you’re thinking about selling, remortgaging, or simply curious, knowing what your home is worth is useful. Here’s how to get a reliable estimate without paying for a surveyor.
1. Check what similar properties sold for
The most reliable indicator of your home’s value is what comparable properties nearby have actually sold for. HM Land Registry records every residential sale in England and Wales, and we make this data freely searchable.
Start by searching for your address on House Price Finder. You’ll see:
- Your property’s sale history — every recorded transaction going back to 1995
- Nearby sales — recent transactions on your street and surrounding area
- Area price trends — whether prices in your postcode have been rising or falling
Pay attention to properties that are similar to yours in type (detached, semi, terrace, flat), size, and condition. A 3-bed semi that sold two doors down last month is a far better indicator than a studio flat that sold on the next street.
2. Use our automated valuation tool
Every property page on House Price Finder includes a free valuation estimate. Our engine works by:
- Finding comparable sales within a carefully calculated radius of your property
- Matching by property type — we compare like with like (detached vs detached, etc.)
- Adjusting for size — using floor area data from EPC records to calculate a price per square metre
- Applying market trends — factoring in how local prices have moved since each comparable sold
- Weighting by similarity — properties on the same street, with similar room counts, similar EPC ratings, and in the same neighbourhood deprivation band are weighted more heavily
The result is an estimate with a confidence range. A “high confidence” result means we found several strong comparables; “low confidence” means the data was thinner and the estimate is less certain.
To use it, search for your address, navigate to the property page, and click Get Valuation.
3. Check your EPC
Your Energy Performance Certificate contains useful information beyond just the energy rating. It records:
- Floor area in square metres
- Number of habitable rooms
- Construction age band
- Property type and built form
- Wall, roof, and window descriptions
This data feeds directly into our valuation engine. If your property has an EPC on record, you’ll see it displayed on the property page.
4. Look at the local market trend
A property in an area where prices are rising 5% annually is worth more today than it was 6 months ago. Conversely, falling prices mean your property may be worth less than the last recorded sale.
Check the trend for your postcode area on our area data pages. We show year-by-year price movements going back to 1995, broken down by property type.
5. Factor in improvements
Our automated estimate is based on comparable sales data and doesn’t know about any improvements you’ve made. If you’ve added an extension, converted a loft, or renovated the kitchen, your property may be worth more than the estimate suggests.
As a rough guide:
- Loft conversion — typically adds 10–15% to value
- Single-storey rear extension — adds 5–10%
- New kitchen — adds 3–5%
- New bathroom — adds 2–4%
Our valuation tool lets you input extension square metres to adjust the estimate accordingly.
When to get a professional valuation
A free online estimate is useful for a ballpark figure, but you’ll need a formal valuation from a RICS-qualified surveyor if you’re:
- Remortgaging — your lender will commission their own valuation
- Selling — estate agents provide free market appraisals (though these can be optimistic)
- Settling an estate — probate may require a formal valuation
- Disputing council tax — you’ll need evidence of value at the relevant banding date
For most other purposes — understanding your equity, deciding whether to sell, or simply keeping track — a data-driven online estimate gives you a solid starting point.
