Are Estate Agent Valuations Accurate?
Estate agents don't provide independent valuations. They set asking prices. Here's what the data shows about the gap between what agents say and what properties actually sell for.
Estate agent "valuations" are not independent or regulated assessments. They are marketing prices set by someone who earns commission from the sale. Agents may overvalue a property to win the instruction from a seller, or undervalue to achieve a quick sale. The most reliable way to check an agent's figure is to compare it to actual Land Registry sold prices for comparable properties in the same postcode.
An estate agent valuation isn't really a valuation
When an estate agent visits your home and tells you it's "worth" £325,000, that's not a valuation in any regulated or formal sense. It's a marketing appraisal, a suggested asking price designed to help the agent win your business and get the property listed.
The distinction matters. A valuation implies objectivity and expertise. What you're actually getting is a sales pitch. The agent wants you to sign with them rather than a competitor, and the number they suggest is shaped by that goal, sometimes more than it's shaped by what the property would actually sell for.
This isn't to say all agents are dishonest. Many are experienced professionals who price properties sensibly. But their incentives are different from yours, and understanding that difference is the first step to making better decisions about buying or selling.
Estate agents typically charge 1–2% of the sale price. They earn more when the price is higher, but they also earn nothing if the property doesn't sell. This creates a tension: some agents lean toward optimism to win instructions, while others lean toward caution to ensure a quick sale. Neither approach is necessarily aligned with getting you the best outcome.
Estate agent valuation vs surveyor valuation
There's a common confusion between what an estate agent tells you and what a surveyor or RICS-qualified valuer would say. They serve entirely different purposes.
| Estate agent | RICS surveyor | |
|---|---|---|
| Purpose | Set an asking price to market the property | Provide an independent assessment of market value |
| Who pays them | The seller (via commission on sale) | Whoever commissions the valuation (often the lender) |
| Regulated? | No formal regulation on pricing | Yes, governed by RICS Red Book standards |
| Method | Local knowledge, comparable listings, sales strategy | Comparable sold prices, property condition, market data |
| Liability | None if the price turns out to be wrong | Professional indemnity insurance; legally accountable |
| Cost | Free (it's part of winning your business) | £150–£1,500+ depending on property and scope |
When a mortgage lender sends a surveyor to value a property, that surveyor is looking at what comparable properties actually sold for, not what agents are listing them at. If there's a gap between the agent's asking price and the surveyor's valuation, the lender will base the mortgage on the lower figure. This is one of the most common ways buyers discover that an agent's price was optimistic: the mortgage valuation comes back below the agreed purchase price, and the deal is suddenly in trouble.
Why estate agent valuations are often wrong
There are several structural reasons why estate agents consistently get pricing wrong. Sometimes too high, sometimes too low, and often varying between agents for the same property.
They're competing for your instruction. If you invite three agents to value your home, each one knows the others are also visiting. The temptation to quote a higher price than the competition is strong, because sellers naturally gravitate toward the agent who tells them their house is worth the most. This is known in the industry as "buying the instruction" and it's extremely common.
They rely on listing prices, not sold prices. Agents often benchmark your property against what similar homes are currently listed for. But listing prices are aspirational. They represent what other agents hope to achieve, not what buyers have actually paid. It's a circular reference: agents price based on other agents' prices, with no anchor to reality.
They factor in their own sales strategy. An agent who prefers quick sales may undervalue slightly to generate immediate interest. An agent who likes to test the market may overvalue and plan to negotiate down. The number they give you reflects their preferred approach as much as the property's worth.
Local knowledge has limits. Agents know their patch, but they also have blind spots. They may overweight a recent sale on the same street while ignoring a broader downward trend in the postcode, or vice versa. They're human, and their judgement is coloured by which sales they happened to be involved in.
Common pricing tactics to watch for
Understanding these tactics helps you see past the number and evaluate what an agent is actually doing.
Buying the instruction
The agent quotes an unusually high price to win your business, knowing the property is unlikely to sell at that level. After a few weeks of low interest, they'll recommend a price reduction, but by then you've signed a contract (often with a sole agency tie-in period) and switching agents is difficult. The result is wasted time and a property that looks stale on the market.
The lowball for a quick fee
The opposite strategy: an agent prices low to generate a flurry of interest and a quick offer. They earn their commission faster, even if the sale price could have been higher with more patience. This is particularly common with agents who operate on high volume and low service.
Anchoring to the top of the range
An agent says "I'd market it at £300,000–£325,000" and then lists at £325,000. The range gave the appearance of moderation, but you're now priced at the top end. If comparable sold prices are closer to £290,000–£300,000, the "range" was already optimistic before they picked the upper limit.
Cherry-picking comparables
The agent justifies their figure by referencing one or two high sales, perhaps a renovated property or a sale that happened during a particularly hot market. They omit the lower sales that would paint a more balanced picture. This is why looking at the full range of sold prices in a postcode matters more than any single example.
Check the agent's figure against real sold prices
PropertyTruth analyses Land Registry data by postcode, so you can see what properties actually sold for, not what agents listed them at. Compare any valuation to the facts in under a minute.
Search your postcode Dashboards from £0.99 · No subscription neededHow to check an agent's figure yourself
You don't need to take an agent's word for it. Here's how to verify any valuation using freely available data.
If you're buying (not selling), checking agent valuations is just as important. The asking price on the property you want was set by an agent using the same imperfect process described above. Knowing what comparable properties actually sold for gives you the confidence to make an evidence-based offer and the ammunition to negotiate.
The data doesn't have an agenda. Agents do.
PropertyTruth gives you Land Registry sold prices, trends, and averages for your specific postcode, so you can check any agent's figure against what's actually happening in the market.

Why do different estate agents give different valuations?
Different agents use different pricing strategies. Some price high to flatter the seller and win the instruction, knowing they'll negotiate down later. Others price competitively to attract more viewings and trigger a bidding war. The variation reflects their sales strategy, not a genuine disagreement about the property's value. Comparing all their figures to Land Registry sold prices will quickly show you which agent is closest to reality.
Should I get multiple estate agent valuations?
It can be useful to see the range, but the spread between agents often tells you more about their tactics than about your home's value. A more reliable approach is to check Land Registry sold prices for comparable properties yourself. That way you have an independent benchmark before any agent walks through your door, and you can assess each one's figure against evidence.
Do estate agents overvalue houses on purpose?
Some do, yes. The practice is called "buying the instruction". They quote a high price to persuade the seller to choose them, then recommend reductions once the property sits unsold. It's not illegal, but it wastes the seller's time and can leave the property looking stale. The best defence is knowing what comparable homes have actually sold for before you invite agents to value yours.
How can I check if an estate agent's valuation is fair?
Look up actual Land Registry sold prices for similar properties in the same postcode over the last 12 months. Compare the agent's figure to the median sold price for the same property type. If the agent's number is significantly higher than what comparable homes have sold for, the valuation is likely inflated. PropertyTruth does this analysis for you by postcode.
What's the difference between an asking price and a sold price?
The asking price is the marketing price set by the estate agent, and it's what the seller hopes to achieve. The sold price is what a buyer actually paid, recorded by the Land Registry after the transaction completes. They can be quite different. The sold price is the only figure that reflects a real market transaction between a willing buyer and seller.
Is there a free way to check Land Registry sold prices?
Yes. The Land Registry publishes raw transaction data that anyone can download for free. However, it comes as large CSV files covering millions of records and requires filtering and analysis to be useful for a specific postcode. PropertyTruth processes this data and presents it as clear dashboards showing averages, trends, and comparable sales by postcode.
