Signing with an estate agent feels like a formality — a quick scrawl before the real business of selling your home begins. But the contract you sign at that point can have a significant bearing on how much of your sale proceeds you actually keep, and how much freedom you have if things don't go to plan. Before you put pen to paper, it is worth understanding exactly what you are agreeing to.
Sole Agency vs. Sole Selling Rights
These two terms sound similar but carry very different consequences.
Sole agency means the agent is the only one marketing your property, but if you find a buyer yourself — through a neighbour, a colleague, or a family connection — you pay nothing to the agent.
Sole selling rights is far more restrictive. Under this arrangement, the agent is entitled to their commission regardless of who introduces the buyer. Sell to your next-door neighbour's cousin without any involvement from the agent, and you could still owe them thousands of pounds.
Always check which term your contract uses. Many sellers sign what they assume is a standard sole agency agreement and only discover the distinction when an unexpected bill arrives after completion.
The Tie-In Period
Most estate agents require you to commit to them for an initial period — typically 8 to 16 weeks — during which you cannot switch to a different agent without penalty. That is not unreasonable in itself; agents invest time and money marketing your property. The problem arises when the tie-in period is excessively long or when the terms for exiting are buried in the small print.
Look for:
- The length of the tie-in. Anything beyond 16 weeks is worth questioning, particularly in an active market.
- The notice period after the tie-in. Many contracts require 28 days' written notice before you can terminate. If you miss this window, you could find yourself locked in for another month even after the tie-in has officially ended.
- Automatic renewal clauses. Some agreements roll over unless cancelled by a specific date. Mark that date in your calendar the moment you sign.
The "Ready, Willing and Able" Buyer Clause
This is one of the most contentious clauses in estate agency contracts, and one that catches many sellers off guard. Under some agreements, an agent is entitled to commission if they introduce a buyer who is "ready, willing and able" to purchase — even if you decide not to sell.
If you change your mind, accept a higher offer elsewhere, or the sale falls through because of something on your side (such as a change in personal circumstances), you could still owe the agent their full fee. The key question to ask is whether commission is due only on completion or whether it can be triggered earlier.
Reputable agents will confirm in writing that their fee is payable on completion only. If an agent is reluctant to make that commitment, treat it as a warning sign.
Referral and Ancillary Services Fees
Estate agents increasingly make money not just from their commission but from referring you to solicitors, mortgage brokers, surveyors, and other services. This is not inherently problematic, but it can create a conflict of interest — the agent may have a financial incentive to recommend a particular solicitor even if that firm is not the best fit for your sale.
Under the Estate Agents Act 1979 and subsequent regulations, agents are required to disclose any financial interest they have in services they recommend. In practice, these disclosures are not always made prominently.
Ask your agent directly: "Do you receive a referral fee from any of the services you recommend?" If the answer is yes, you are under no obligation to use those services, and shopping around is almost always worthwhile.
The Commission Rate and What It Covers
Estate agent fees in the UK typically range from around 0.9% to 3% of the sale price, plus VAT. That spread is wide, and what sits within the fee can vary considerably.
Before signing, confirm in writing:
- Whether the fee includes VAT or is quoted exclusive of it
- Whether professional photography, floorplans, and portal listings (Rightmove, Zoopla) are included or charged separately
- Whether there are any withdrawal fees if you take the property off the market
- Whether the fee increases if the property sells above a certain price (tiered commission structures are legal but worth understanding)
A lower headline rate can sometimes mask additional charges that push the total cost higher than a competitor quoting a slightly higher flat fee.
Multi-Agency Agreements: Knowing When They Make Sense
If you appoint more than one agent simultaneously under a multi-agency agreement, each agent works competitively to find a buyer. Only the agent who introduces the successful buyer earns commission. However, multi-agency fees are substantially higher — often 2% to 3% or more — and the arrangement can sometimes lead to a fragmented marketing effort, with agents focusing on quick wins rather than building a coherent campaign for your property.
Multi-agency can make sense for unusual or high-value properties with a limited pool of buyers, or when a sole agent has demonstrably underperformed. For most sellers, it is worth exhausting a well-chosen sole agency arrangement first.
How to Protect Yourself
Read the entire contract before signing — not just the headline fee. If any clause is unclear, ask for it to be explained in plain language and confirm the explanation in writing (email is fine). The Property Ombudsman publishes guidance on what a compliant estate agency contract should look like, and it is worth familiarising yourself with that before you sit down with an agent.
You are also entitled to negotiate. Commission rates, tie-in periods, and the terms around the "ready, willing and able" clause are all areas where agents will often show flexibility, particularly in a competitive market.
Tools like Keyzee can help you understand what your property might be worth before you engage an agent, giving you a stronger starting position when it comes to negotiating both the asking price and the agency terms. Going into that first meeting with a clear sense of your property's value makes it much harder for an agent to justify an inflated commission on the basis that they alone possess that knowledge.
The contract you sign with your estate agent is a legally binding agreement, and the terms matter. Taking an hour to read it carefully — and asking questions about anything that is not immediately clear — can save you a significant amount of money and a great deal of stress further down the line.
