House Valuation: How Much Is My House Worth?
Published by Property Insights UK · June 2026 · 12 min read
A house valuation gives you an estimate of how much your property may be worth in the current UK market. An online property valuation tool can provide a quick and useful guide by using available housing market data, such as local price trends and the House Price Index. This can help you understand your home's likely value before selling, remortgaging or reviewing your finances. For the most complete picture, it is also worth comparing recent sold prices and considering factors such as property condition, location, size and local buyer demand.
Key information
- ✓A house valuation gives you an estimate of what your home may be worth in today's property market.
- ✓You can get an instant house valuation online, usually by entering your postcode and property details.
- ✓Online valuations are quick and often free, but they should be treated as a guide rather than a guaranteed sale price.
- ✓Recent property sold prices are one of the best ways to understand what similar homes have actually achieved.
- ✓A local estate agent valuation can be more realistic because it considers condition, improvements, demand and buyer behaviour.
- ✓A mortgage valuation is different from a house survey and is mainly for the lender's benefit.
- ✓If you are selling, remortgaging, going through probate, divorce, tax planning or legal matters, a professional valuation may be needed.

Value my house free →What is a house valuation?
A house valuation is an estimate of how much a property is worth. It is usually based on recent sold prices, property type, size, location, condition, local demand and wider market trends.
For sellers, it helps decide an asking price. For buyers, it helps judge whether a property is fairly priced. For mortgage lenders, it helps check whether the property provides enough security for the loan.
How can I value my house?
1. Use an online house valuation tool
An instant house valuation or online property valuation is often the fastest place to start. Many tools work as a house value calculator by postcode: you enter your postcode and address, and sometimes your property type, number of bedrooms and general condition.
These tools typically use past sale prices, local market data and comparable properties. Rightmove explains that its estimates use public information, its own property data and similar nearby properties that have sold or are for sale.

2. Check property sold prices
Property sold prices show what buyers actually paid, not just what sellers asked for. That makes them one of the most reliable inputs when researching UK house prices or house prices by postcode.
GOV.UK lets users search how much a property sold for in England and Wales and check UK house price averages by region, county or local authority. You can also browse sold prices quickly on Property Insights UK via our UK sold house prices tool.
3. Compare similar homes for sale
Look at properties with the same number of bedrooms, property type, condition and location. Asking prices are useful for context, but they are not the same as sold prices. A home listed above recent completions may still sell below its asking price if buyer demand is soft.
4. Ask local estate agents
Estate agents can compare your home with recent local sales and current buyer demand. This is useful because online tools may not properly judge condition, extensions, layout, garden size or presentation.
5. Get a professional valuation if needed
For legal, tax, probate, divorce or lending purposes, a formal valuation by a qualified surveyor or valuer may be required rather than an indicative online estimate.
Are online house valuations accurate?
Online house valuations can be useful, but they are not always accurate. They work best for standard homes in areas where many similar properties have recently sold. They are less reliable for unusual homes, rural properties, recently renovated homes, extensions, poor condition properties or areas with limited sales data.
Zoopla explains that online valuations may not fully capture unique features, renovations or property condition. Rightmove also notes that accuracy varies by area and property, and estimates are usually more accurate for typical properties where there are many similar homes nearby.
That is why it helps to cross check any instant house valuation against recent sold prices on your street or postcode. Our Area IQ tool is useful for comparing district level trends and comparable sales.
What affects the value of my house?
Many factors influence what a buyer will pay. The most common include:
- Location and postcode
- Property type: detached, semi-detached, terraced or flat
- Number of bedrooms and bathrooms
- Internal floor space
- Garden, parking and garage
- Condition and presentation
- Extensions, loft conversions and renovations
- Energy efficiency rating. See our EPC checker
- School catchment area
- Transport links
- Local crime, amenities and employment. Try our crime by postcode tool
- Local buyer demand
- Current mortgage rates and affordability
- Recent sold prices nearby
Buyer affordability and mortgage rates. Even if a house is attractive, buyers may offer less when mortgage costs are high because monthly repayments affect what they can afford. Use our mortgage calculator to sense check affordability in the current rate environment.
What is the difference between a house valuation and a mortgage valuation?
A house valuation estimates what your property may sell for. It can be done by an estate agent, online tool or surveyor.
A mortgage valuation is carried out for the lender. Its purpose is to check whether the property is suitable security for the mortgage. It is not the same as a detailed house survey.
A house survey looks at the condition of the property in more detail, especially defects, damp, structural problems and repair risks.
How much are house valuations?
Many online house valuations are free. Many estate agents also offer free valuations because they hope to win your instruction if you decide to sell.
However, a formal valuation by a RICS surveyor or professional valuer may cost money, especially if it is needed for probate, divorce, tax, court, shared ownership, Help to Buy, or legal purposes. A RICS Red Book valuation for probate or legal use often costs from around £150 to £500 or more depending on property size and location.
Property Insights UK offers a free indicative online property valuation for research and planning. It is not a substitute for a formal RICS valuation where one is required.
How to get a more accurate house valuation
Use this checklist to improve confidence in your estimate:
- Check at least three online valuation tools.
- Look at recent sold prices in your street or postcode.
- Compare similar homes currently for sale.
- Adjust for condition, extensions and renovation quality.
- Consider local demand and how quickly homes are selling.
- Ask two or three local estate agents for a valuation.
- Use a qualified surveyor if you need a formal figure.

House prices in the UK and London
UK house prices vary strongly by region, property type and local demand. National averages can be misleading because they blend very different markets into one headline figure.
London house prices can vary heavily even between neighbouring postcodes, so local sold price evidence is more useful than national averages. Browse London postcode districts or search any district in Area IQ to see what buyers have actually paid near you.
