How does a house valuation work in the UK?

What is a house valuation?

A house valuation is a professional estimate of what your property would sell for in the current market. It is not a guarantee of price, and it is not what a buyer will definitely pay. It is one informed person's view of what a willing buyer would pay a willing seller today, based on the property and the local market.

Valuations matter because they shape every decision that follows. They set the asking price, they influence the agent you choose, and they affect what a mortgage lender will lend against the property.

What are the three main types of house valuation in the UK?

There are three valuation routes in common use. Each one answers a different question, costs a different amount, and takes a different length of time.

How does an estate agent valuation actually work?

An estate agent valuation is the most common route for someone thinking about selling. You book a visit, the agent walks around your home for half an hour to an hour, and you receive a suggested asking price either in person or by email a day or two later.

What the agent is doing on that visit is matching your home against recent local sales. They look at sold prices for similar properties in your road or your postcode, then adjust up or down for the things that make your home different.

• Recent sold prices on your street and in your postcode sector, usually from HM Land Registry's Price Paid data.
• Square footage, number of bedrooms, and number of bathrooms.
• Condition of the kitchen, bathrooms, windows, and roof.
• Garden, parking, and outside space.
• School catchments, transport links, and any local planning that could affect demand.
• Current buyer activity in the area, including how long similar listings are taking to sell.

An estate agent valuation is free because winning your instruction is how the agent earns. That is also why two agents can value the same home tens of thousands of pounds apart. One may quote a realistic figure that matches the data. Another may quote higher to win the listing, then push for reductions later. This is why most sellers in 2026 ask more than one agent for a valuation before they pick.

How does a RICS surveyor valuation work?

A RICS valuation is a formal report written to the standards in the RICS Red Book, the global standard published by the Royal Institution of Chartered Surveyors. The surveyor inspects the property, then issues a written report with a market value figure and supporting evidence.

You usually only need a RICS valuation when something legal or financial depends on the number being defensible. Probate, divorce settlements, shared-ownership staircasing, Capital Gains Tax calculations, and Help to Buy redemptions all typically require one. Most lenders also commission their own RICS valuation as part of the mortgage process, paid for as a separate fee or rolled into the mortgage product.

The cost reflects the level of survey. A standard valuation report sits at the lower end of the range. A Level 2 HomeBuyer Report sits in the middle. A Level 3 Building Survey, used for older or unusual properties, sits at the top.

How accurate are online house valuations?

Online valuations use an automated valuation model, or AVM. The tool looks at sold prices for similar properties in your postcode, applies an average price-per-square-foot, and returns a figure within seconds.

The accuracy depends on the data the model has on your specific home. In a postcode with plenty of recent same-style sales, the figure can be close. In a road with mixed property types, an extension you have built, or a recent renovation, the model has no way to know and the figure can drift 10 to 20 percent in either direction.

Treat an online valuation as a rough orientation, not a real price. It is useful for an early-stage gut-check. It is not what you list at.

How long does a house valuation take?

Timing varies sharply by route. Online tools return a figure in seconds. Estate agents are in and out of the property in well under an hour. RICS surveys take longer on site and longer to write up.

How much does a house valuation cost in 2026?

Estate agent valuations remain free in the UK in 2026. The agent is competing for your instruction, so the visit is the cost of doing business.

RICS valuations are paid. A standard valuation report typically starts around £250 for a flat or small terrace and rises with the size and age of the property. HomeOwners Alliance publishes survey-cost guidance that puts a Level 2 HomeBuyer Report at roughly £400 to £950 for most homes and a Level 3 Building Survey at £600 to £1,200 or more for larger or older properties.

Online valuations are free at the point of use. Some portals will pass your details to local agents when you submit. Whether you receive follow-up calls depends on the tool's privacy model.

How do I get the most reliable picture of my home's value?

The single most reliable signal is several local estate agents valuing the same property against the same brief, in the same week. Each agent brings their own read of the local market. Looking at the spread, the reasoning, and the marketing plan side by side gives you a far better picture than any single number.

If a legal or financial process requires a defensible figure, instruct a RICS chartered surveyor. The fee buys you a written report that holds up with HMRC, lenders, probate registries, and courts.

If you only want a rough early look, use one or two online tools to set a mental baseline. Then book at least three real valuations before you list.

An estate agent's valuation is an opinion of what a buyer will pay. A surveyor's valuation is a formal record of what the market says today. They answer different questions, so they often produce different numbers.

Common questions about UK house valuations

How does ValuQ fit in?

ValuQ is a UK property platform where homeowners get free, side-by-side valuations from competing local estate agents, anonymously, on one screen. You submit your property once, several local agents return their valuations and marketing approach within 48 hours, and you compare them all before any agent gets your contact details. It replaces the cycle of phoning around for three separate appointments with one anonymous brief and one comparison view.

It is free for homeowners, always. Agents only pay when they win their first instruction through ValuQ.
