There is no universally better route. There is only the route that better matches your property, your timeline, and your appetite for chain risk.
The headline numbers
| | Estate agent | Auction | | --- | --- | --- | | Typical net | 93–98% of asking | 94–100% of expected | | Time to completion | 4–6 months | 28 days | | Seller fees | 1–2% commission + VAT | £0 (buyer pays premium) | | Fall-through risk | ~33% nationally | ~3% | | Best for | Move-in-ready owner-occupier homes | Anything condition-challenged, time-sensitive, or atypical |
When the estate agent route wins
- Property is in move-in condition
- You can wait 4–6 months
- You're happy to renegotiate post-survey
- Local market is hot and stock is short
When auction wins
- You need certainty by a specific date
- The property would attract surveyor down-valuations
- It's atypical (unusual leasehold, mixed-use, refurb required)
- You've already had two fall-throughs at the agent
How fall-through risk weighs against commission
A 2% saving on commission means little if your sale collapses in week 16 and you start again. Across 100,000 UK property sales each year, around a third fall through — costing the average seller £3,000 in wasted fees and a four-month delay. That said, most sales that don't fall through complete at a higher net price on the open market, so the comparison depends on your odds, not the averages.
Auction's unconditional contract removes the fall-through risk on the day of the hammer, but it does so by accepting a narrower buyer pool and often a lower hammer than a patient open-market sale might reach.

Sale method comparison
Where auction has the edge
- Single buyer pool. Cash buyers and investors who can act in 28 days. No survey-based renegotiation — but also no owner-occupier competition.
- Public competitive bidding. Open-market negotiations happen one-on-one with someone whose interest you can't verify.
- No "subject to mortgage." Mortgage clauses don't exist in traditional auction contracts.
Where the open market has the edge
- Owner-occupier buyers typically bid harder than investors. They're buying a home, not a yield, so move-in-ready properties usually fetch more.
- Marketing time lets the right buyer find you, especially for unusual properties that an auction crowd may undervalue.
- No buyer's premium suppressing what bidders are willing to offer.
A simple decision rule
Ask yourself two questions:
- Could you list this on Rightmove and confidently expect three offers in 60 days? If yes, agent. If no, auction.
- Do you have four months to wait? If yes, agent. If no, auction.
Two yeses → agent. Two nos → auction. Mixed → run the calculator and pick by the net number.
