Estimates, not financial advice

These calculators are for planning and comparing scenarios. Always speak to a qualified financial adviser, a mortgage broker or your lender for accurate figures, and before making any financial decision.

Cost of Selling a House

Estate agent fees, conveyancing, the EPC, removals, and stamp duty on whatever you buy next. The figures below are estimates: what you actually pay varies by region, by how much demand there is for your property, and by who you instruct. Replace them with the real numbers as quotes come in and you book each service. Stamp duty is the exception, worked out from the published bands.

Selling
Standard costs

What you expect the house to sell for. The agent's fee and every percentage in the results come from this figure.

£

Commission for marketing the house and seeing the sale through, charged as a percentage of what it sells for. Sole agency is typically 1% to 2%, but can be higher. Online agents tend to charge a flat fee instead.

%

Agents usually quote without it, so a 1% fee really costs 1.2%. Turn this off only if you have been told the quote already includes VAT.

Yes

The solicitor or licensed conveyancer who handles the contract, the title and the money. Include disbursements: the small charges for title documents and bank transfers.

£

An EPC is required by law before the house can be advertised. One lasts ten years, so if you bought recently the existing certificate may still be valid and this is zero.

£

A closing or deeds-release charge some lenders make when the mortgage is paid off. It is a fixed amount and it will be named in your original mortgage offer.

£

A penalty for leaving a fixed deal before it ends, usually 1% to 5% of the balance. Zero if your fixed term has finished, or if your lender lets you take the same deal to the new house.

£

A removal firm for moving day. How much there is to move, packing, dismantling furniture, storage between completions and a long distance all push this up.

£
Additional costs None of these apply to every sale, so they start at nothing. Fill in the ones that apply to yours.

What a freeholder or managing agent charges to supply the paperwork a leasehold sale needs. Nothing to pay on a freehold house.

£

A clean before the photographs are taken, and often a second one once you have moved out and the house is empty.

£

The jobs that would show in the photographs or come back in the buyer's survey. Worth separating from the rest, because it is the one item you can decide not to spend.

£

A one-off insurance policy the buyer's solicitor may ask for where paperwork is missing, such as consent for an old extension. Usually cheaper than obtaining the document, and usually paid by the seller.

£

Whatever your sale needs that is not listed above. Storage between completions and a short let if the dates do not line up are the usual ones.

£
Onward Purchase

What you expect to pay for the next house. Stamp duty is worked out from this, and it is usually the largest single cost of moving.

£

Each nation charges its own tax on a property purchase, and the bands are different in each, so the same price does not cost the same everywhere.

England & Northern Ireland

First-time buyer relief and the second-home surcharge both change which rates apply, so this moves the tax more than anything else on the page.

Moving home

More work than the selling side, which is why it usually costs more: searches on the property, enquiries with the seller's solicitor, and registering you as the new owner.

£

Your own inspection of the house, which is not the same as the lender's valuation. There are three levels: a condition report at roughly £250 to £400, a homebuyer survey at £400 to £800, and a full building survey at £800 to £1,500 or more. All three vary with the area, the size and age of the property, and anything unusual about it, so treat these as a guide and get a quote.

£

What the lender charges to set the loan up. It can often be added to the mortgage instead of paid up front, but then you pay interest on it for the whole term.

£

A broker's fee, buildings insurance from the day you exchange, and the small things on arrival such as new locks.

What does it cost to sell a house in the UK?

For the sale on its own, budget 2% to 3% of the sale price. On a £350,000 sale that is about £8,500, and the estate agent is well over half of it. Selling is the cheap half of moving: buying again adds stamp duty, a second set of legal fees, a survey and usually a lender fee, which on a £400,000 purchase comes to around £13,000.

That split is why so many people underestimate a move. The costs of selling are proportional and predictable. The costs of buying are dominated by a tax that jumps in bands, and it has to be paid in cash on completion.

Which costs fall on the seller?

  • Estate agent commission. Quoted as a percentage, and the quote may or may not include VAT at 20%. A "1%" fee is really 1.2%, which is £700 of difference on a £350,000 sale. Sole agency is cheaper than multi-agency. This is the largest cost you have any real influence over, and plenty of agents will negotiate the rate, so it is worth asking before you sign.
  • Conveyancing on the sale. The legal fee plus disbursements: bank transfer fees, Land Registry documents, and the leasehold pack if the property is leasehold. Ask for a quote that includes disbursements rather than the headline fee alone.
  • The EPC. You cannot legally market a property without a valid Energy Performance Certificate, and they last ten years, so check before paying for another.
  • The leasehold management pack. Usually flats only, ordered from the freeholder or managing agent, and both the price and the wait vary enormously. It is a common cause of delay as well as cost.
  • Mortgage exit or deeds release fee. A small administrative charge for closing the loan, separate from any early repayment charge.
  • An early repayment charge, if you are inside a fixed term. Typically a few percent of the balance outstanding. Porting the mortgage to the new property usually avoids it.
  • Removals. More with the amount you are moving, more with distance, more again if the completion dates do not line up and you need storage.
  • Getting the house ready, and filling gaps in the paperwork. A clean before the photographs, whatever repairs you judge worth doing, and an indemnity policy if the buyer's solicitor finds consent missing for old work.

Do I pay stamp duty when I sell my house?

No. Stamp duty is paid by the buyer. You pay nothing on the sale, and you pay it on whatever you buy next. This causes a lot of confusion around selling costs, and the figure is large enough that it will change your calculations completely if you cost it on the wrong side.

How much is stamp duty when I move?

It depends on the price, on where in the UK you are buying, and on whether you will own more than one property afterwards. All three taxes are charged on slices: each rate applies only to the part of the price inside its band, not to the whole price. England and Northern Ireland charge Stamp Duty Land Tax, Scotland charges Land and Buildings Transaction Tax, and Wales charges Land Transaction Tax, with different bands in each.

First-time buyers

In England and Northern Ireland relief gives you nothing to pay up to £300,000 and 5% from £300,000 to £500,000. Above £500,000 the relief disappears entirely rather than tapering: at exactly £500,000 a first-time buyer pays £10,000, and at £500,001 they pay £15,000. That £5,000 cliff for one extra pound is worth knowing before you make an offer near the threshold.

Scotland raises the nil-rate band from £145,000 to £175,000 instead, which is worth at most £600. Wales has no first-time buyer relief at all.

Second homes and buy to let

If you will own more than one residential property at completion, a surcharge applies, and each nation does it differently. England and Northern Ireland add five percentage points to every band, including the nil-rate band, so tax starts from the first pound. Scotland adds the Additional Dwelling Supplement at 8% of the whole purchase price once the price reaches £40,000. Wales uses a separate, higher set of bands starting at 5%.

If you are replacing your main residence but have not yet sold it, you may have to pay the surcharge and reclaim it when the old home sells. Check the deadline for your nation, as it is strict.

What does it cost to sell and buy at the same time?

Here is the default scenario on this page in full: a £350,000 sale and a £400,000 purchase in England, replacing a main residence.

Agent fee at 1.2% plus VAT. Conveyancing, survey and removals are typical figures rather than quotes; your own will differ.

£8,490 of that is the sale, which is 2.4% of the sale price. The other £13,000 is the purchase, and £10,000 of it is one tax bill. The whole move costs 6.1% of what the house sold for.

The house sale what-if calculator works the same example from the other end: it takes these costs and your outstanding mortgage and tells you what is left for the deposit. The button above carries every figure across, so you do not have to type them twice.

Which of these can I actually reduce?

In rough order of how much room there is to move:

  • The estate agent fee. Negotiable, and on a £350,000 sale each 0.2% is £840 with VAT. Get three valuations and compare the fee, the tie-in period and whether it is sole agency.
  • Conveyancing. Quotes vary by several hundred pounds for the same work. Compare total figures including disbursements; the cheapest headline fee is often not the cheapest total.
  • The mortgage product fee. Often avoidable by taking a slightly higher rate, which is worth comparing properly rather than assuming the fee-free deal is better. On a large loan the rate usually wins; on a small one the fee usually does.
  • The early repayment charge. Usually avoidable by porting the mortgage rather than redeeming it, or by timing the move for the end of the fixed period.
  • Stamp duty. Essentially fixed, but it is banded, so the price you agree matters more than it looks near a threshold. Negotiating £405,000 down to £400,000 near a band edge can save more than the £5,000 itself.

Common questions

Are estate agent fees negotiable?

Usually, and it is the largest cost you have any influence over. Ask whether the quoted percentage includes VAT before comparing it with anything, and ask what happens if you withdraw or switch agent. A longer tie-in is worth something to the agent and should be worth a lower rate to you.

When do I pay the costs of selling a house?

Most come out of the sale proceeds on completion, so you never write a cheque for them: the estate agent and both sets of legal fees are settled by your conveyancer from the money coming in. Stamp duty is due within 14 days of completion in England and Northern Ireland, and 30 days in Scotland and Wales. A survey, the EPC and any mortgage product fee are usually paid up front, which means they are the ones that need cash in hand before the sale has produced any.

What if the sale falls through?

Costs already incurred are generally not recoverable. The EPC survives for the next attempt, and a conveyancer will usually charge a reduced abortive fee rather than the full amount, but a survey on a purchase that collapses is money gone. This is the main argument for not paying for a survey until the chain looks solid.

There are insurance policies that cover some of the risk of a transaction falling through, sold as home buyer or seller protection. Read the terms closely before buying one: what they pay out on, what they exclude and how long you have to claim all vary, and whether the premium is worth it depends on how exposed your own chain is.

Do I pay capital gains tax on the sale?

Usually not, on your own home. Private Residence Relief covers a property that has been your only or main residence throughout the period you owned it. Second homes, buy to let and property that was let out for part of the time are a different matter. The what-if calculator has more on this. Always seek proper financial advice before making any decisions: everything here is an illustration and a rough estimate.

Fee figures on this page are typical starting points, not quotes, and the tax bands were checked against the official sources on 18 October 2026. Rates change at Budgets.
