How to Check an Estate Agent's Track Record and Sold Prices

Choosing an estate agent based on a glossy brochure or a confident pitch is one of the costliest mistakes a home-seller can make. The good news is that the data you need to make a properly informed decision is largely free and publicly available — you just need to know where to look and what questions to ask.

Why does an estate agent's track record matter?

An agent's track record tells you whether they consistently sell homes like yours, at or close to asking price, within a reasonable timeframe — and that directly affects how much money ends up in your pocket. A single percentage point difference on a £350,000 property is £3,500; an extra three months on the market means three more months of mortgage payments, stress and uncertainty.

Most sellers spend more time researching a new fridge than they do vetting the person who will handle their largest financial asset. Don't be that seller.

Where can I find an estate agent's sold price data?

The most reliable starting point is the HM Land Registry Price Paid Data, which records every residential property sold in England and Wales. It's free to search at gov.uk and is updated monthly. You can search by postcode and street to see what properties actually sold for — not just what they were listed at.

For Scotland, equivalent data is held by Registers of Scotland, and in Northern Ireland by Land & Property Services NI.

Beyond the Land Registry, three tools are particularly useful:

• Rightmove's Sold House Prices tool — search by postcode and filter by property type and date. Crucially, it shows the original listing price alongside the final sold price, so you can calculate the sale-to-asking-price ratio yourself.
• Zoopla's Property Valuation tool — gives estimated values and recent sold comparables in the same area.
• Nethouseprices.com — another free aggregator of Land Registry data, useful for quick postcode-level searches.

None of these tools tell you which agent sold each property, which is where your next step comes in.

How do I find out which properties a specific agent has sold?

The most practical method is to search the agent's name directly on Rightmove or Zoopla and filter results to "Sold Subject to Contract" (SSTC) and "Sold". This shows their current pipeline and recent completions in your area.

You can also ask the agent directly — any decent one should be able to hand you a list of comparable properties they've sold in the last six to twelve months, along with asking prices, achieved prices and time on market. If they can't or won't provide this, treat it as a warning sign. You'll find more on this in our guide to estate agent red flags every seller should know.

What is a sale-to-asking-price ratio and why does it matter?

The sale-to-asking-price ratio (sometimes called "asking price achieved") is the percentage of the original asking price that the agent actually secured at completion. An agent consistently achieving 98–100% of asking price is performing well; one regularly hitting 93–94% may be over-valuing properties to win instructions, then reducing them quietly over time — a tactic known as "overvaluing to underdeliver".

The Property Ombudsman and industry bodies have flagged this practice repeatedly. Always ask an agent for their average sale-to-asking-price ratio across the last twelve months, and ask how they've calculated it (some agents use the reduced asking price, not the original, which flatters their numbers).

What else should I check beyond sold prices?

Sold prices are only one piece of the puzzle. A fuller picture of an agent's track record includes:

How do I check an agent's average days on market?

Rightmove and Zoopla both display listing dates. If you find a property that's been listed for 120 days and only recently gone SSTC, that tells you something about how it was priced or marketed. Equally, if you see an agent's listings repeatedly disappear and reappear (a trick to reset the "first listed" date), that's a red flag covered in more depth in our article on how to vet an estate agent.

Should I check online reviews?

Yes, but with appropriate scepticism. Google Reviews, Trustpilot and AllAgents all carry estate agent reviews. Allagents.co.uk is the most property-specific and includes verified transaction reviews, which carry more weight than anonymous submissions.

Look for patterns rather than individual comments. A cluster of five-star reviews posted in a single week, or a suspiciously high overall score with very few reviews, both warrant a closer look. Equally, one or two negative reviews among dozens of positive ones is fairly normal for any active business.

How do I check an agent's credentials and compliance?

Every estate agent operating in England must by law belong to a government-approved redress scheme — either The Property Ombudsman (TPO) or the Property Redress Scheme (PRS). You can verify membership directly on each scheme's website. Agents must also belong to a Client Money Protection (CMP) scheme if they handle client funds.

Membership of a professional body — such as NAEA Propertymark — is voluntary but signals a commitment to ongoing training and ethical standards. It's worth checking.

Personal agents vs high-street branches vs online agents: how do track records compare?

This is where the type of agent genuinely matters. High-street branches often have high staff turnover, meaning the person who valued your home may not be the one conducting viewings or negotiating your sale three months later. That makes accountability harder to pin down.

A personal estate agent — a self-employed or hybrid agent working independently, often backed by a network such as eXp UK — handles your sale from start to finish. Their personal reputation is directly on the line with every instruction they take. That makes their track record both easier to verify (it's their own, not a branch's) and more meaningful.

If you want to match with a personal estate agent who knows your local market and can show you their own performance data, that's exactly what our matching service is designed to do.

What should I ask an agent about their track record?

When you sit down with any agent — whether in person or on a video call — ask them these specific questions:

1. What is your average sale-to-asking-price ratio over the last twelve months?
2. What is your average time to find a buyer, and time to completion?
3. How many of your agreed sales fell through last year, and why?
4. Can you show me three comparable properties you've sold on my street or nearby?
5. Who will handle viewings and negotiations — you, or someone else?

Question five is particularly revealing. An agent who will personally conduct every viewing and lead every negotiation has a very different offering to one who passes viewings to a junior or to a central team. Our full guide to 15 questions to ask an estate agent before you instruct covers this in detail.

How do I use comparable sold prices to sense-check a valuation?

Before any valuation appointment, do your own homework. Search HM Land Registry or Rightmove for properties sold on your street or in your immediate postcode in the last six to twelve months. Note the property type, size, condition (insofar as you can judge from listing photos) and sold price.

This gives you a realistic anchor. If an agent values your three-bedroom semi at £50,000 above every comparable sale in the road, ask them to explain specifically what justifies the premium. If they can't, the valuation is likely a tactic to win your instruction — not an honest assessment of market value.
