What estate agents charge, and what changes it

There is no standard estate agency fee in the United Kingdom. There is no regulator setting one, no scale, and no rate everybody charges. What there is instead is a set of choices, and each one moves the number. Understanding the choices is most of the work.
Percentage or fixed
A percentage fee is a share of what the property sells for. A fixed fee is a set amount whatever it sells for. Neither is automatically better and they behave very differently.
A percentage keeps the agent’s interest pointing the same way as yours, at least in theory: a higher sale price means a bigger fee. A fixed fee is easier to budget for and can work out cheaper on a higher value property, but the agent gets the same whether they hold out for a better offer or take the first one.
The practical question is what happens at the margin. On a percentage, ask what the difference in their fee would be between two offers a few thousand apart. It is usually small enough to be worth knowing about, because it tells you how much the structure alone is really doing to keep them pushing.
VAT is not a detail
Fees are sometimes quoted with VAT and sometimes without, and the gap between the two is not small. A fee quoted without VAT will look competitive against one quoted with it, and the comparison is meaningless.
Ask every agent for the total including VAT, in writing, as a number of pounds on the valuation they have just given you. If an agent is reluctant to put that on paper, that is itself an answer.
Sole agency, multi agency, and the words in between
Sole agency means one agent has the right to sell it for an agreed period. Multi agency means several are trying and whoever sells it is paid, usually at a higher rate. There are also arrangements described as sole selling rights, which are not the same as sole agency and can mean a fee is due even if you find the buyer yourself.
These are contract terms with real consequences and the names are genuinely confusing. Read what you are signing, and if a term is not clear, ask what it would mean in a specific situation: if my neighbour buys it, do I pay you? If I take it off the market, do I pay you? If I instruct somebody else in three months, do I still pay you?
The tie in
Most sole agency agreements run for a set period before you can leave, and there is often a notice period on top of it. Both are negotiable and both are worth negotiating, because a tie in is the only thing standing between you and moving on if it is not working.
Ask for the length in weeks, ask for the notice period, and ask when the clock starts. A long tie in is not a scandal, but you should agree to it knowingly rather than discover it later.
What should be included
Photographs, a floorplan, a listing on the major portals, viewings and negotiation are normally part of the fee. Things that are sometimes extra include premium listings, professional photography beyond the standard set, videos, and the energy performance certificate you are legally required to have. None of those extras are wrong to charge for. They are wrong to discover afterwards.
Cheap is a strategy, not a con
A lower fee is not evidence of a worse agent, and a higher one is not evidence of a better one. What a fee tells you is how a business has chosen to make its money, and the honest version of the conversation is an agent explaining what you get for theirs.
The question worth asking a cheaper agent is what they do less of. The question worth asking a more expensive one is what they do more of. Both should have an answer that survives one follow up question.
What we would say
Get every fee in writing, including VAT, as a total in pounds. Then choose on everything else.
