Selling a £300,000 house yourself saves you between about £3,200 and £3,900 in cash, depending on whether you pay a flat fee to reach the big portals or use no agent at all. After tax it is less than that, because the fee you avoid was also money you could set against a taxable gain. So if the house was ever let out, or was a second home, roughly a fifth to a quarter of the saving goes back in tax. The work is real as well. You price it, market it, show it, vet the buyer and chase the paperwork yourself. It is entirely legal, thousands of people do it every year, and what follows is the whole process.
If the decision is not made yet, our page on whether you can and should sell without an estate agent weighs it up and sets out who it suits. This page assumes you have decided and want the method.

Can you sell a house without an estate agent, and what does it save?
Yes, and nothing in the process requires you to use one. The rules that govern estate agents bite on businesses acting on someone else's instructions to sell property. Sell your own home and you are not doing that, so those rules do not reach you at all. There is no licence, no permission and nobody to notify.
The saving is the fee. The HomeOwners Alliance puts the average sole agency fee at 1.42% including VAT in its 2026 guide to the cost of selling a house. On a £300,000 house that is £4,260. Which?, using Rightmove data in its June 2026 guide, puts the typical figure a little lower at around 1.3% including VAT, or £3,900 on the same house. Either way it is the biggest single line in the cost of selling, and the only one you can remove outright. Our page on what estate agents charge to sell a house breaks that fee down.
Replacing the agent is not free. On the route that reaches the portals you pay a flat fee of about £999, the entry price at two of the named providers on MoneySavingExpert's July 2026 list, plus the £80 identity check one of them charges outside that headline. That is £1,079, so the cash saving on a £300,000 sale is about £3,181. Use no agent at all, with a board, a private sale site and word of mouth, and a private listing package runs £0 to £400 on the same figures, which puts the saving nearer £3,860 and the work squarely on you. The arithmetic, in six lines.
- Agent fee avoided: 1.42% including VAT on a sole agency sale, about £4,260 on a £300,000 house (HomeOwners Alliance, 2026).
- What you spend instead: £999 plus an £80 identity check to reach the portals, or £0 to £400 with no agent at all (MoneySavingExpert, updated 1 July 2026).
- Listing package: £129 to £1,599 by provider, or £300 to £1,500 as a typical band (MoneySavingExpert; Which?, June 2026).
- Energy certificate: £35 to £120 on our own EPC cost guide, and you pay it either way.
- Conveyancing: paid on either route, so it is not part of the saving.
- What the saving is worth after tax: on the portal route and a chargeable gain, £2,608 at the basic rate and £2,418 at the higher one.
One caution before the steps. The saving of £3,181 is 1.1% of the price, and £3,860 is 1.3%. Sell for that much less than an agent would have achieved and it has gone. Tax does not move the break-even either, because it shrinks the saving and the shortfall by the same proportion. Nobody publishes a reliable figure for what private sales fetch against agent sales, so treat it as arithmetic rather than evidence, but do treat it as the risk that matters. The money is not lost in fees. It is lost in the price.
The ten steps, in order
The whole process fits on one page.
- Step 1. Price it. Sold prices rather than asking prices, plus three free agent valuations.
- Step 2. Order the energy certificate. You need a valid one before the house is marketed.
- Step 3. Get photographs and a floorplan. Most listing packages include both.
- Step 4. Choose the listing route. A paid listing service for the big portals, a private sale site, a board, local groups, or all of them.
- Step 5. Write the listing. Accurate, complete, and no claim you cannot evidence.
- Step 6. Run the viewings. Two of you, fixed slots, a note of who came.
- Step 7. Take offers and check the buyer. Funds, lender, chain, solicitor and timescale, in writing.
- Step 8. Fill in the property forms. This is where your legal exposure sits.
- Step 9. Instruct a conveyancer, or do the transfer yourself. Then exchange and complete.
- Step 10. Report the tax. Only where the house was not your own home throughout.
Can you list on Rightmove or Zoopla without an agent?
Not directly. Rightmove's own seller guide is blunt about it: "sellers and landlords aren't allowed to list properties themselves on Rightmove as a private seller", and the portal "only list homes from registered estate and letting agents". To appear there, the guide says, "you will need to work with an agent who has an active membership with us". Zoopla works the same way.
So the DIY guides all point you at a paid listing service, and that works. It carries a twist worth knowing about. A business that only publishes adverts, or only gives a buyer and a seller a way to talk to each other, sits outside the estate agency rules altogether. That is the legal gap those services were built in. But a business outside those rules is not a registered agent, and only registered agents can put a property on the portal.
In practice the two do not coexist. If the route gets you on to Rightmove, it almost always runs through a business doing estate agency work, and one that therefore has to belong to an approved redress scheme. If the route genuinely sits outside the rules, it will not reach the portal. That is good news for your protection and awkward for the "no agent" framing, and it is the single most useful test to apply when you are comparing services: ask which approved redress scheme they belong to. A clear answer tells you they are an agent in law, whatever the marketing says. No answer tells you to ask how, exactly, your house is going to appear on the portal.
Expect £129 to £1,599 for the listing itself, on MoneySavingExpert's July 2026 figures, or £300 to £1,500 as the band Which? gives in its June 2026 guide. The cheap end means you write the listing and field every call. Compare the current offers rather than the ones a guide recommends, because free listing brands in this corner of the market get bought, rebranded and folded into paid agents. The middle option, a full online agent, is covered on our page about online estate agents.
How do you price your house without an agent's comparables?
Use sold prices, not asking prices. Asking prices are hopes. Sold prices are evidence, they are public, and Land Registry price paid data plus the sold price tools on the major portals give them to you free. Look for the same street, the same house type and the last twelve months, in that order of preference, and adjust for the obvious differences in size and condition.
Then book three valuations with local agents. They are free, they carry no obligation, and each one arrives with the comparables you were missing. There is nothing underhand in this. Agents give free valuations to win instructions and accept that most do not convert. Take the middle of the three figures as your anchor, discount the highest one, and remember that the highest valuation is the oldest trick in the business.
Keep the evidence. Save the comparables, the valuation letters, the listing and the photographs, and put them somewhere you will find them in five years. If the house was ever let out, the sale price and the costs of sale both feed a tax calculation later. Our guide to what to keep after a property sale sets out the full list, and our capital gains tax on property guide has the mechanics.

What paperwork do you need before you list?
Five things, and the first two hold up the marketing rather than the sale.
- A valid energy certificate. Required before the property is marketed, valid for ten years, so check the one from your own purchase first. Our pages on energy performance certificates and what an EPC costs cover both.
- Your title documents. Most titles are registered, and your conveyancer downloads them. If the title is unregistered, find the deeds early, because that alone can add weeks.
- The TA6 property information form. The sixth edition came into force on 30 March 2026 according to the HomeOwners Alliance guide to the form. Editions matter, so do not fill in a copy pulled from an old search result.
- A fittings and contents form. What stays, what goes, what is for sale separately. Cheap to get right and a common cause of a bad tempered completion day.
- The leasehold pack, if the house is leasehold. The freeholder or managing agent supplies it, they charge for it and they take their time. Order it the week you list, not the week you accept an offer.
Add anything that proves work was done properly: building regulation certificates, the boiler service record, guarantees for damp, roofing, windows or a new kitchen, and the planning permission for the extension. A buyer's solicitor will ask for all of it, and every item you cannot produce becomes a delay or a price chip.
How do you handle viewings, offers and buyer checks on your own?
Viewings first. Do them in pairs, never alone, and book fixed slots rather than letting people drop in. Take a name, a phone number and an address for everyone who comes, and call the number back before the visit. Open the doors, then get out of the way. Sellers talk too much, and the two questions worth asking are why they are moving and how quickly they need to.
Offers are where the missing agent is felt most, because there is no buffer. Take every offer in writing, even if it arrives by phone, and reply to every one, including the ones you reject. Never accept on the number alone.
Then check the buyer, and ask for the same things an agent would ask for. A mortgage agreement in principle from a named lender, dated within the last month or two. Evidence of the deposit, which usually means a recent bank statement, a broker's letter or written confirmation from whoever is gifting it. The name of the solicitor they have already instructed, not the one they intend to. Their position in the chain, and how many links sit behind them. A ready buyer sends all five within a day or two. A buyer who stalls on every item has answered the question anyway, and it costs you nothing to keep marketing until the survey is booked.
Do you need a conveyancer, and can you do it yourself?
You do not have to instruct one. Almost everybody does, and there is a real reason to.
Preparing the document that transfers a property is reserved work, which normally means only an authorised professional may do it. There is an exemption for an individual who does that work without any fee, gain or reward, and that exemption is why handling your own sale is lawful. Two limits sit inside it. You cannot do it for anybody else for payment. And acting unpaid gives you no standing to supervise someone else who is doing it. So the accurate statement is narrow: you may prepare the transfer of your own property because you are not being paid for it.
Separately, and on its own footing, HM Land Registry expects to see unrepresented parties. Its guidance says that private individuals complete form ID1, and that evidence of identity is needed for any party who is not legally represented. Section B of that form has to be completed by a conveyancer, a Chartered Legal Executive or a licensed probate practitioner regulated by the Council for Licensed Conveyancers. There is a separate form for verification by other professionals, but ID1 is the one a private individual uses, and it needs one of those three. There is a carve out where the land is worth £6,000 or less, which will never cover a house.
Put those two things together and the position is procedural rather than prohibited. Doing your own transfer is not banned. It is registered through a documented identity process, and you will still need a professional to confirm who you are. Note also what the registry guidance does not say: it says nothing about the reserved work exemption, and the two points stand separately.
The practical answer for most sellers is still to instruct someone. Sale side conveyancing runs to £800 to £1,500 plus small disbursements on MoneySavingExpert's July 2026 figures, and to "average between around £610 and £950" plus £200 to £300 of transfer disbursements on the HomeOwners Alliance's. Those two ranges do not agree, and averaging them would invent a figure, so ask three firms to quote in writing and compare what the disbursements include. A leasehold title, a mortgage to redeem or a chain of four all argue for a professional. One small correction while you are budgeting: the Land Registry registration fee belongs to the buyer's application, not to yours, so it does not go on a seller's cost list at all, whatever the DIY guides say.
What are you on the hook for when you answer questions about the house?
Misrepresentation, and it is the one exposure that does not shrink when the agent goes. If you give an answer about the property that turns out to be wrong, and the buyer relies on it, they can claim damages from you. That liability attaches to a person, not just to a business, so a private sale carries exactly the same weight as any other.
The property information form is where it lives. The duty, as the HomeOwners Alliance guide to the form puts it, is to complete it "truthfully, completely and as accurately as you can from your own knowledge". Three habits keep you safe. Answer from what you actually know. Write "not known" where that is the truth, rather than guessing at something helpful. And never leave out a dispute, a leak, a boundary argument or a refused insurance claim because you hope it will not come up.
The consumer trading rules that replaced the old 2008 regulations in April 2025 work differently. They bind traders, meaning people acting for business purposes, so they land on the listing service or the portal rather than on you. That is not a loophole to enjoy. It simply means your exposure is contractual and sits under the misrepresentation route instead.
Then there is what you give up. An estate agent has to tell you the fee, and when it becomes payable, before you sign anything. An agent also has to belong to an approved redress scheme, so a complaint has somewhere to go. Sell privately and neither protection is running, because there is no agent to owe you the disclosure and no scheme to complain to about yourself. In exchange, you keep the fee. That is the trade, stated plainly.
What does it actually cost, and what does it save after tax?
Two sourced sets of figures, published a month apart in 2026, and they do not always agree. Both are shown rather than blended. This is the sale side only: our cost of selling a property hub and our page on the cost of moving house add the buying side and the move itself.
| Item | Typical cost | Source |
|---|---|---|
| Listing package, to reach the big portals | £129 to £1,599 by provider; £300 to £1,500 as a band | MoneySavingExpert, updated 1 July 2026; Which?, 8 June 2026 |
| Energy performance certificate | £35 to £120, and you pay it on either route | Our own guide to EPC costs |
| Photography and floorplan | Usually inside the listing package. No reliable published average when bought separately, so get a quote | Figure declined |
| Conveyancing, sale side | £800 to £1,500, or around £610 to £950 | MoneySavingExpert; HomeOwners Alliance |
| Sale disbursements | Title deeds £10 to £20, bank transfers £20 to £50, money laundering checks £10 to £20; or £200 to £300 of transfer disbursements plus £10 for deeds | MoneySavingExpert; HomeOwners Alliance |
| Identity check for form ID1 | No Land Registry fee. Whatever the professional charges to complete section B, so ask before you book | Figure declined |
| Total, all in | £1,004 to £3,309 across the priced rows above, on the lower disbursement set. Selling with no agent at all, where the listing line is £0 to £400 instead, comes to £875 to £2,110 all in | The rows above; MoneySavingExpert, updated 1 July 2026 |
Now the saving on a real sale price, with the tax netted off. The house is a former rental worth £300,000, so the gain is chargeable, and the spend is a £999 flat fee, the entry price at two of the named providers on MoneySavingExpert's July 2026 list, plus the £80 identity check one of them charges outside that headline. The energy certificate is not in this sum, because you pay for it whichever route you take. These figures price the portal route; with no agent at all the saving is nearer £3,860 and the tax works the same way.
| Line | Amount on a £300,000 sale, portal route | Where the figure comes from |
|---|---|---|
| High street fee at 1.42% including VAT | £4,260 | HomeOwners Alliance average, 2026 |
| What you spend instead | £1,079 | £999 flat fee (MoneySavingExpert, 1 July 2026) plus an £80 identity check charged outside it |
| Total cash saving | £3,181 | £4,260 less £1,079 |
| Saving after tax at 18% | £2,608 | £3,181 less tax at 18% |
| Saving after tax at 24% | £2,418 | £3,181 less tax at 24% |
When you sell a property at a taxable gain, the costs of selling come off that gain before the tax is worked out, and the agent's commission is one of them. Pay £4,260 of commission and it reduces the taxable gain by £4,260. Pay £1,079 instead and only £1,079 comes off. So you keep £3,181 of cash and hand back roughly a fifth to a quarter of it, leaving £2,418 at the higher rate.
That only applies if there is a chargeable gain at all. If the house was your only home throughout, private residence relief usually covers the whole gain, there is nothing to deduct anything from, and the entire £3,181 is yours. If it was let out or was a second home, the after tax column is the real number, and the tax has to be reported and paid within 60 days of completion: our page on capital gains tax payment deadlines has the dates.
One correction worth having before you budget. You did the cleaning and the redecorating yourself, and neither counts. Nor does the removal van, the storage, or an early repayment charge on the mortgage. They are real money and they belong in your moving budget, but they do not reduce the gain.
