Why do estate agents give such different valuations?

The estate agent who walks through your house has thirty minutes, a tape measure, and a phone full of recent sales data. Three of them, on three separate days, will give you three different numbers, and the variation is not all professional disagreement. Knowing where the difference comes from is how you avoid choosing the wrong agent for the wrong reason.

Why three agents give three different numbers

Estate agent valuations differ for three main reasons.

• Evidence weighting. One agent leans on comparable sold prices from the Land Registry, another on current asking prices in the same postcode, a third on personal experience of the street.
• Market read. Agents work the local market on different days under different pressures, and that affects the figure they think a buyer will pay this month.
• Incentive. The agent who values highest often does so to win the listing. The agent who values realistically does so to sell it.

What evidence does a sound valuation rest on?

• Recent sold prices from comparable homes on the same street or postcode sector, ideally within the last six months.
• Current asking prices on similar homes for sale right now, adjusted for how long each has been on the market.
• Sales the agent has personally completed nearby, with the actual achieved figures and time on market.
• Knowledge of local buyer demand right now: how many viewings their other listings are getting, how many offers, and at what price.
• An honest read of the current market direction. The RICS April 2026 UK Residential Market Survey, published 14 May 2026, reported a national house price balance of negative 34, the weakest reading since November 2023.

How wide is a normal valuation gap?

A gap of around 5 percent between the highest and lowest valuation is normal and reflects professional judgement on a real property. A gap of 10 to 20 percent is common and is usually a sign one of the figures is doing something the others are not. A gap wider than 20 percent is a red flag and almost always means the highest figure is a tactic, not a valuation.

What do common valuation tactics signal?

What questions should I ask each agent about their valuation?

How do I spot the realistic valuation?

1. Get three valuations from three different agents on the same brief: same details, same photos, same access.
2. Ask every agent for their comparable sales evidence in writing before any tie-in conversation begins.
3. Compare the three figures side by side and identify the outlier. The outlier is usually either too high or too low for a reason.
4. Cross-check the middle figure against HM Land Registry sold prices for the same postcode sector in the last six months. The figure should sit in the same range.
5. Pick on the strength of the evidence and the strategy, not on the size of the number.

The agent who values highest is rarely the agent who sells fastest. They are often the agent who asks for a price reduction six weeks in.

How does ValuQ approach this?

ValuQ is a platform that gives UK homeowners free, side-by-side property valuations from competing local estate agents, on the same brief, without the seller giving up their identity until they choose to. The structure removes the easiest tactic in the playbook: agents cannot inflate a valuation to win a seller's attention when every other valuation sits visible alongside their own.
