Most sole agency tie-in periods run for 4 or 12 weeks. The notice period normally sits on top of the tie-in rather than inside it, so a 12-week tie-in with 4 weeks' notice keeps you with that agent for 16 weeks. The HomeOwners Alliance calls 4 or 12 weeks the most popular terms and says more than that is unnecessary. It has also seen 20-week tie-ins with a 4-week notice period bolted on, which is close to six months.

If you have already signed, the number that matters is not the one you were quoted. It is the tie-in, plus the notice, plus what the contract says about buyers the agent introduced.

  • Typical tie-in: 4 or 12 weeks on sole agency, and longer than that is unnecessary (HomeOwners Alliance)
  • Notice period: commonly runs on top of the tie-in, so 12 plus 4 means 16 weeks
  • Sole selling rights: you owe the fee even if you find the buyer yourself
  • Cancellation: 14 days from signing, if you signed away from the agent's office
  • Tax: the fee on the completed sale comes off your gain, a withdrawal fee does not

How long is an estate agent tie-in period?

The tie-in is the minimum time you agree to keep that agent on. During it you cannot instruct anyone else, and in most contracts you cannot serve notice either. Four or twelve weeks is what you should expect. No published limit fixes the length for you: the rules control how your terms have to be explained, not how long the lock-in runs.

That makes the tie-in the easiest term to negotiate. Agents guard the fee, because the fee is how they are measured. They will often trade the tie-in instead. Ask for 4 weeks and a short notice period, say you are ready to sign today on those terms, and put it in an email.

For the fee itself, see how much estate agents charge to sell a house. Selling in the capital has its own numbers, in average London estate agent fees. This page is about your terms, not the price.

How do you get out of an estate agent contract before the tie-in ends?

Three routes out, and only one is the notice clause.

  • Serve notice. On most contracts your notice runs after the tie-in, not inside it. Serving early rarely starts the clock early.
  • Cancel in the first 14 days. This applies where you signed at home or agreed the contract remotely.
  • Challenge the contract. If you were not told about the fees before you signed, the agent cannot simply enforce it.

Here is how the arithmetic lands. You sign a 12-week sole agency with 4 weeks' notice. By week 6 you have had two viewings and no offers, and you want to move. Your notice served in week 6 does not bite until the tie-in has run. You serve it again at the end of week 12 and you go free at the end of week 16. Ten weeks after you decided to leave, you are still stuck.

Two questions decide whether you have another way out. Were you told what the fees were and when they fall due, before you signed, and where were you when you signed? And be clear that leaving the contract is not leaving the fee, because a buyer that agent introduced can still cost you.

What is the difference between sole agency and sole selling rights?

These two phrases look alike and cost very different amounts. Your contract has to explain both in set wording, so check yours against the words below.

Under sole agency, you owe the fee if unconditional contracts for the sale are exchanged with a buyer the agent introduced during the sole agency period, a buyer the agent had negotiations with during that period, or a buyer another agent introduced during that period.

Under sole selling rights, you owe the fee if contracts are exchanged during the period, in the required wording, "even if the purchaser was not found by us but by another agent or by any other person, including yourself". You also owe it after the period ends where the buyer was introduced or negotiated with during it.

Read that second one twice. Sole selling rights catches the buyer you found yourself, the neighbour who always liked the house, the friend who offered over dinner. Selling to someone you know carries its own tax traps, covered in selling a house below market value.

If your contract does not carry these explanations in that form, raise it with the agent in writing before you sign anything else.

Online and fixed-fee contracts differ again: you often pay before anyone views. Their terms are set out in online estate agents in the UK. For how the fee models compare, see the cheapest estate agent fees.

Can two estate agents both charge you for one sale?

Yes, in the wrong circumstances. You leave one agent, instruct another, and your eventual buyer turns out to have first seen the house through the first agent.

The leading case is Foxtons Ltd v Pelkey Bicknell, decided by the Court of Appeal in April 2008. It is the one to read if two agents are chasing you.

  • What it decided. "A purchaser introduced by us" means the person the agent introduced to the purchase, not merely to the property. The homeowner won and the fee claim failed.
  • The bit that gets misquoted. Guides often say the case decided an agent must be the effective cause of the sale. On the wording of that contract the court said the opposite: no such requirement had to be implied.
  • Where effective cause lives. It is a general principle rather than something that case created, and it did not need implying there because the reading above already decided the point. The court treated it as a term readily implied in a residential consumer case, unless your contract or the facts rule it out.
  • On double fees. More than one fee can be payable, but far more rarely than the agent in that case argued.

If two invoices land, do not pay either straight away. Ask both agents to set out in writing when they first introduced your buyer and what they did next. Then take advice. The homeowner won that appeal on exactly that sequence.

What does "ready, willing and able purchaser" mean?

This is the third phrase your agent has to explain, and it is the one that costs you money with no sale in sight. Where your contract carries it, the fee can fall due once the agent produces a buyer who is ready and able to go ahead. Whether you then sell is beside the point. You can owe a full fee with no sale and nothing coming in to pay it with. The HomeOwners Alliance advice is blunt: do not accept it.

So look for the phrase before you sign, and ask for it to be taken out. Most agents drop it rather than lose the instruction. If it is already in your contract and the agent is claiming under it, get advice before you reply.

Can you cancel within 14 days if you signed at your kitchen table?

Most agency contracts are signed in your own home, at the end of the valuation visit. That makes them off-premises contracts. The right that follows exists whether or not anyone told you about it.

You have 14 days from the day you signed to cancel, with no reason needed. Contracts agreed remotely carry the same right. Cancel in writing and keep proof of when you sent it. The interesting part is what happens once you have asked the agent to start straight away, which most sellers do.

  • You asked them to start early. For a contract signed in your home, that request has to be in a durable form, which in practice means in writing.
  • You then cancel inside the 14 days. You pay a proportionate amount for the work actually done, not the whole fee.
  • You lose the right. Only where the service has been fully performed after such a request and you acknowledged the right would go.
  • You were never given the cancellation information. The window extends well past 14 days and you pay nothing for the work done in it.

So dig out the pack you were handed on the day, and if it holds no cancellation notice, keep it exactly as it came.

What the agent had to tell you about withdrawal fees before you signed

Before you sign, the agent must tell you when the fee becomes payable, how much it is or how it is worked out, and what other payments or charges you might face. That last limb catches withdrawal fees, early-termination charges, marketing, photography, floor plans and the energy certificate. Later changes have to be disclosed too.

Where you were not told, the contract is not enforceable by the agent unless a court allows it. The court can reduce the sum or discharge it, looking at how far the agent was at fault and what the failure cost you.

You will not find a reliable published figure for a typical withdrawal fee. Treat any number on an invoice with suspicion unless you can find it in the contract you signed. The energy certificate is the one exit cost with a published price range, in our guide to EPC costs. If the agent will not put every charge in one email before you sign, that is your answer.

Every sales agent has to belong to an approved redress scheme. So if you are already in dispute, complain to the agent first and then take it to their scheme, which costs you nothing.

Which of these payments reduce your capital gains tax bill?

Where your sale is taxable, some selling costs come off the gain. The list is closed. It is not a general allowance for the costs of selling: HMRC's own guidance says so in four words, and the list has not moved.

The fee you pay the agent who actually sold the home is on that list. A withdrawal fee, an early-termination charge or a second fee to an agent who did not sell is not. That is the cost of getting out of a contract, not a cost of making the sale.

Say you complete through a second agent who invoices £4,000, while the first agent charges you a £600 withdrawal fee. Both figures are illustrative. The £4,000 comes off your gain, and because you cannot reclaim the VAT you deduct it including VAT. The £600 does not. Interest added to an unpaid fee never comes off either. Where you pay a disputed claim purely to get the sale over the line, there is a separate argument that the payment protected your title. Treat it as an argument to put with paperwork behind it, not a settled deduction.

If it was your only or main home throughout, none of this is likely to bite, because the gain is usually covered. For a let property or second home, see tax when you sell a rental property.

What to keep, and for how long

You have to evidence the deduction years after the argument with the agent has faded. Keep your signed contract and terms, every email about fees, both agents' invoices, and anything showing when a buyer first saw the house. If your sale is taxable, keep it all for at least five years after the 31 January that follows the tax year of sale, the floor for a let property. Our guide to record keeping for property sales has the full list.

Still choosing an agent? Work out what the whole sale will cost you first. Our cost of selling calculator gives you what you owe if you leave and what you owe if you stay, in under a minute. Then negotiate your tie-in as hard as you negotiate the fee, because it is the term agents move on most readily.

If the terms are the reason you are hesitating rather than the fee, selling without an estate agent removes the contract altogether. The cost of selling a property sets out every line of the bill.
