If you’re planning a remortgage or thinking about selling, one number drives everything.
What is the property actually worth?
This page gives you a structured way to estimate it.
The calculator uses past values and regional market movements to project a current range.
It’s a directional view based on index data. Not a valuation.
Use it to sense-check your position before taking the next step.
House Price Index calculator
Start with what you know.
• last known property value
• when that value was recorded
• the region
• the point in time you want to estimate
The output shows how the market has moved and what that implies for your property.
This reflects general trends in the area.
It won’t account for specifics like condition, layout, or demand for your exact property.
Other ways to estimate your value
Index data gives you one angle.
Local evidence gives you another.
Look at:
• similar properties currently for sale
• recent sold prices nearby
• homes on your street with similar size and layout
• how quickly properties are selling in your area
Estate agents can add another layer.
If you speak to a few, you’ll usually see a range form.
You can also use the Land Registry service to see recent sold prices.
What actually drives differences in value
Two houses on the same street can price differently.
Common drivers:
• micro-location within an area
• condition and level of modernisation
• size, layout, and extensions
• school catchments and transport links
• local demand and turnover
• underlying issues like damp, wiring, or structureThis is why index-based estimates and real valuations can diverge.
Adding Value
Not all improvements translate directly into price.
Typical levers:
• kitchens and bathrooms
• extensions or loft conversions
• improving layout or usable space
• external presentation
Some changes increase value.
Others mainly improve saleability.
Final considerations
Most people can get to a rough range themselves.
But if you’re making a decision, you’ll need a proper valuation.
Lenders will instruct their own when assessing a mortgage.
Buyers will form their own view based on what’s available nearby.
Use the calculator to frame your position.
Then refine it with real-world evidence before acting.

Most borrowers compare rates before they know whether a lender will actually like their case.
That’s how people waste time with the wrong bank, get weaker offers, or end up with avoidable declines.
The readiness check gives you an early read on how your case is likely to land, where the pressure points are, and whether lender choice needs more care.
