What does it really cost to sell with an estate agent?
The headline is the commission, but the real cost of an estate agent sale in 2026 is commission + EPC + conveyancing + months of running costs + the risk of a fall-through. On a typical South Wales home that can add up to several thousand pounds and 6-12 months of your time. Here’s the full breakdown so you can compare properly.
We’re David and Jason at House Buyers Wales — we’re not anti-agent (for the right house, an agent gets you more). But you should see the whole bill, not just the headline.
1. Estate agent commission
High-street agents in South Wales typically charge 1%-2.5% + VAT. On a £200,000 sale that’s roughly £2,400-£6,000 including VAT. “No sale, no fee” sounds reassuring, but it also means the agent is paid only when the deal completes — which is why some push you to accept a quick, lower offer.
2. EPC
You can’t market a home without a valid Energy Performance Certificate — via an estate agent, this might cost you usually £100-£150 + VAT.
3. Conveyancing (your solicitor)
You pay your own legal fees on an open-market sale — typically £1,000-£3,500 + VAT including disbursements. (For comparison, when you sell to House Buyers Wales, we cover the legal fees — including yours.)
4. The cost most people forget: months of running costs
This is the big one. While the house is on the market and going through a chain — 6 to 12 months end-to-end in 2026 — you’re still paying:
- Council tax (and the empty-home premium of up to 300% if it’s vacant)
- Buildings insurance (more if it’s unoccupied; you’ll need a specialist policy)
- Mortgage repayments, if there’s still a loan on it
- Utilities and standing charges
- Repairs, maintenance and cleaning
Six months of these costs can easily run into multiple four figures.
5. The hidden cost: fall-throughs
Almost half the homes estate agents list never sell at all (Zoopla, 2026). And even after a sale is agreed, around a third fall through before completion — a buyer’s mortgage declined, a survey renegotiation, or a chain collapsing. Each time, you’re back to the start, paying the running costs again while you re-market.
So what’s the real number?
On a £200,000 South Wales home, a smooth agent sale can cost £4,000-£10,000+ in fees and several thousand more in months of bills — before you factor in price-chipping after a survey, or a fall-through resetting the clock. That’s the figure to weigh against a fixed cash offer with no fees and a guaranteed date.
