Mortgage question
Can I renegotiate the house price after a bad survey?
Yes, a bad survey is legitimate grounds to reopen price negotiation before exchange. The strongest cases are surveyor-quantified defects or a lender down-valuation. Typical reductions in 2026 come in at 2–7% of the purchase price, often at the midpoint between the asking price and the figure fully adjusted for repair costs. Back your ask with written contractor quotes.
When is renegotiation actually reasonable?
Renegotiation is reasonable on two triggers: a surveyor’s quantified defects, and a lender down-valuation. Both are independent, professional assessments — not subjective opinion — which makes them credible negotiating levers rather than buyer’s remorse.
Reasonable defects include: roof replacement needed, subsidence indicators, failed damp-proof course, rewire required, boiler failure, failed render, rotten timbers, unauthorised extensions needing regularisation. Cosmetic items — tired kitchen, scuffed paint, outdated bathroom — rarely move a seller because they’re visible at viewing and are usually already priced in.
What’s a typical reduction?
Typical reductions are 2–7% of the agreed purchase price. Worked example on a £300,000 agreed purchase:
| Scenario | Typical asking reduction | New price |
|---|---|---|
| Single issue with £5k repair quote | 1–2% (£3k–£6k) | £294k–£297k |
| Multiple issues totalling £15k | 3–5% (£9k–£15k) | £285k–£291k |
| Major structural, £40k+ | 7–15% (£21k–£45k) | £255k–£279k |
| Lender down-valuation by £15k | Usually match the valuation | £285k |
Sellers rarely give you 100% of the repair quote — you’ll usually settle at the midpoint. If the repair is £15,000 and you ask for £15,000 off, expect a counter of £7,500–£10,000.
What’s the exact process, step by step?
The renegotiation process is five steps:
- Read the survey carefully and list the defects with page references. Focus on quantified items.
- Get 2–3 written contractor quotes for each major defect. This is the single most persuasive evidence.
- Write (don’t just call) to the estate agent summarising the findings and the evidenced repair cost, and state your reduced offer. Keep it factual and polite — anger loses negotiations.
- Give a deadline — typically 3–5 working days — so the seller can’t stall.
- Be prepared to walk. You’re still pre-exchange, so there’s no financial penalty if the seller refuses.
Ask your conveyancer to pause searches until the price is agreed — see how long does conveyancing take in 2026 for the wider timeline.
What if the seller refuses?
If the seller refuses you have three options: proceed at the original price; walk away (you lose survey and search fees but not the deposit, which is only committed at exchange); or split the difference. In 2026’s market — with supply up and demand broadly flat — sellers are more amenable to reductions than in the 2021–22 frenzy. But on unusual or high-demand properties, some sellers will simply relist.
Before walking, price-check the alternative. If you’ve already paid £700 for a survey and £350 for searches, walking and starting again on a new property means another £1,050 of spend plus 2–3 months of delay.
Common misconception: “The seller has accepted my offer so the price is locked in”
Price is only locked at exchange of contracts, not at offer acceptance. Until exchange, either party can walk away or renegotiate without penalty — though you’d lose any fees spent so far (survey, searches, some legal fees). This is why post-survey renegotiation is legally straightforward in England and Wales. (Scotland’s missives system is different — by the time the survey lands you’re usually already bound.)
