My agent valued my house highest. Should I trust it?

It feels good when one agent values your home well above the rest. Before you sign with them, it is worth understanding what a valuation actually is, and why the highest one can quietly cost you the most.

Why would an agent value my house too high?

Winning your instruction is how an agent gets the listing. A valuation is an estate agent's opinion of the price your home is likely to achieve, based on recent local sales and current demand. A few agents inflate that opinion to be the most attractive quote in the room, knowing they can ask you to reduce later once your home is already on the market with them.

This is the frustration the whole market knows: three agents, three very different numbers, and the pull to believe the biggest one. The best agent should win on the quality of their pricing and their plan, not on who quotes highest.

What does an over-high asking price actually cost me?

Time, and then money. A home priced above what buyers will pay sits unsold, gets fewer viewings, and then needs a price cut that signals weakness to the very buyers you want to attract.

That gap is around three months. In its May 2026 House Price Index, Rightmove reported that 32% of homes already on the market had seen a price reduction, with buyer choice at its highest for the time of year since 2015. A realistic price from day one sells faster and protects your final figure.

How do I judge a valuation properly?

1. 1. Get more than one valuation

   Invite a few local agents, or use a platform that brings several valuations together, so you see a range rather than a single opinion.

2. 2. Ask for the evidence

   A sound valuation comes with recent sold prices of similar homes nearby. Ask each agent to show you the comparable sales behind their number.

3. 3. Compare the figures side by side

   Put the valuations next to each other. If one is far above the others, treat it as a claim to be justified, not a prize to be accepted.

4. 4. Check the plan, not just the price

   Ask how they will market the home, what fee they charge, and how long they expect it to take. The number means little without the strategy behind it.

5. 5. Decide on merit

   Choose the agent whose pricing is backed by evidence and whose plan you trust, even if their figure is not the biggest.

What should I do if I've already gone with the highest?

If your home has been on the market for several weeks with little interest, the price is usually the reason. Ask your agent for the viewing and enquiry figures, look honestly at the comparable sales, and adjust early. A confident, evidence-led reduction beats a slow drift of small cuts.

The highest valuation wins the instruction. The right valuation wins the sale.

Comparing before you commit is the simplest protection against an inflated number. ValuQ is a platform that gives UK homeowners free, side-by-side property valuations from competing local estate agents, so you can see every figure on one screen and choose on merit rather than on the biggest promise.
