How to Tell if an Estate Agent Is Any Good (Before You Sign)

Choosing the right estate agent is one of the most consequential decisions you'll make in your entire sale. Get it right and the process is smoother, faster and almost certainly more profitable. Get it wrong and you're stuck — sometimes literally, behind a restrictive contract — watching your home stagnate on Rightmove.

Here's how to judge whether an agent is genuinely good before you hand over the keys.

What does a good estate agent actually look like?

A good estate agent sells homes at or close to the asking price, within a reasonable timeframe, with clear and honest communication throughout. That sounds obvious, but it's surprisingly rare. According to Rightmove's own data, properties that have a price reduction have typically been on the market far longer than those that sell first time — a pattern that almost always points back to poor initial pricing or weak marketing.

The difference between a great agent and an average one usually comes down to three things: accurate pricing, proactive buyer matching, and consistent communication. An agent who ticks all three is worth their fee. One who misses even two is a problem waiting to happen.

How do I check an agent's track record before meeting them?

You can check any agent's recent performance for free using tools like Rightmove's agent comparator, Zoopla, or OnTheMarket — just search for sold properties in your area filtered by agent. Look for:

• Sale-to-asking-price ratio: Are they consistently achieving 97–100% of asking price, or are they regularly discounting?
• Average days on market: A lower figure suggests realistic pricing and active buyer matching. A high figure often means overvaluing to win instructions.
• Volume of reductions: If a significant proportion of their listings carry a reduced badge, that's a red flag.
• Fall-through rate: Harder to find publicly, but worth asking directly. A high fall-through rate suggests weak buyer qualification.

Our guide on how to check an estate agent's track record and sold prices walks through this in detail, step by step.

Is the valuation they give me reliable?

A valuation is only as reliable as the agent's willingness to tell you the truth, not what you want to hear. Overvaluing — quoting a high asking price to win your instruction — is one of the oldest tricks in the industry, and it consistently damages sellers.

A home that launches too high sits on the market, picks up a "stale" label and usually sells for less than it would have achieved with a realistic price from day one. Ask any agent you meet to show you the comparable sales evidence behind their figure. If they can't or won't, walk away.

A confident, competent agent will walk you through local sold prices — not just list prices, actual completed sales from HM Land Registry — and explain where your property sits relative to them. That conversation tells you an enormous amount about their honesty and local knowledge.

How quickly should a good agent respond to my enquiry?

A genuinely motivated agent will respond to your initial enquiry within a few hours on a working day — often faster. If you're waiting 24–48 hours just to hear back at the valuation stage, that is almost certainly how they'll handle buyer enquiries once your home is live.

This matters because buyer interest is at its peak in the first two to three weeks of a listing. Slow response times at that critical stage lose offers. Test an agent's responsiveness before you sign, not after.

What questions should I ask an estate agent before instructing them?

The right questions reveal far more than any glossy brochure. Here's a practical list:

1. What comparable sales support your valuation? (Ask to see the evidence.)
2. How many properties are you currently managing, and who will be my main point of contact? (At a busy corporate branch, your named agent may rarely visit your property again after valuation.)
3. What is your average sale-to-asking-price ratio in this postcode? (They should know this without hesitation.)
4. How do you qualify buyers before arranging viewings? (A good agent checks financial readiness, not just availability.)
5. What is your average time to sale from listing to completion?
6. What are your tie-in period and withdrawal terms? (Anything beyond 8–10 weeks with a penalty clause deserves scrutiny.)
7. Will you conduct viewings yourself, or do you outsource them? (Owner-conducted or agent-accompanied viewings consistently outperform unaccompanied ones.)

Personal agent vs high-street branch vs online agent: which performs best?

This is where it's worth being clear about terminology. A personal estate agent (sometimes called a self-employed or hybrid estate agent) is an individual agent — often backed by a network such as eXp UK — who handles your sale personally from valuation to completion. A high-street agent operates from a branch with a team, where your sale may be handled by multiple people. An online agent typically offers a low fixed fee but limited personal involvement.

The continuity point is significant. At a corporate branch, your listing agent may leave mid-sale, your file passes to a colleague who has never seen your property, and the nuanced knowledge built up during viewings evaporates. A dedicated personal agent has their own reputation and income directly on the line for every sale — which focuses the mind.

If you want to find out what's available in your area, you can browse personal estate agents or match with a personal estate agent based on your postcode and property type.

What are the contract red flags to watch for?

Before you sign anything, read the terms carefully. Watch for:

• Tie-in periods longer than 10–12 weeks with no break clause
• Withdrawal fees that apply even if you change your mind before listing
• Sole agency vs multi-agency clauses: understand what you're agreeing to
• Vague marketing commitments: professional photography, floorplans and portal listings should be specified, not assumed
• Automatic rollover clauses that extend the agreement without written notice

Our article on estate agent red flags every seller should know goes into each of these in depth.

How do I know if my current agent isn't performing?

If you're already listed and questioning whether your agent is doing a good job, these are the signs that something is wrong:

• Fewer viewings than expected in the first two to three weeks with no proactive explanation
• Feedback from viewings is slow, vague or non-existent
• Price reduction suggested within weeks of listing (especially without a clear rationale)
• Your agent is difficult to reach and rarely initiates contact
• No evidence of proactive buyer matching — just passive portal reliance
• You feel like a number, not a client

If several of these apply, it may be time to review your contract terms and consider a change. The sooner you act, the less damage to your asking price.
