Your survey report has arrived — and it doesn't make comfortable reading. Damp readings in the basement, cracked render, a roof nearing the end of its life. Before you panic or pull out of the purchase, take a breath. A bad survey report is not necessarily a reason to walk away; it's leverage. Here's exactly how to use it.
Step 1: Read the Report Carefully — All of It
Survey reports use a traffic-light condition rating system: Condition 1 (no action needed), Condition 2 (defects that need attention but are not urgent), and Condition 3 (serious defects requiring prompt action or further investigation). Don't be alarmed by the total number of findings — focus on the Condition 3 items and any items flagged as requiring specialist investigation.
If any part of the report is unclear, call your surveyor. We include a free post-report consultation with every survey precisely because reports need to be understood, not just filed away.
Step 2: Get Specialist Quotes for Major Defects
For significant findings — structural movement, roof replacement, damp-proofing, rewiring — you need written quotes from qualified tradespeople before approaching the seller. Without figures, you're negotiating blind. Estate agents know this, and sellers will resist vague requests.
Aim to get at least two quotes for any item over £2,000. Keep them on headed paper with clear scope of works. These become your evidence.
Step 3: Decide What You're Asking For
You have three options, and you can mix and match:
- Price reduction — the most common approach. Ask the seller to reduce the agreed price by the cost of essential remedial works. This is clean, simple, and doesn't delay completion.
- Seller rectifies the defects — less common, and riskier. You have no control over the quality of work, and it will delay completion. Only suitable for straightforward, well-defined repairs.
- Retention — a sum withheld from the purchase price until agreed works are completed post-completion. Requires solicitor involvement and can complicate matters with lenders.
Step 4: Quantify Exactly What You're Asking
Be specific. "I'd like £15,000 off because the survey was bad" won't get results. Instead: "The survey identified significant roof defects and active damp ingress. We have obtained two contractor quotes totalling £14,750. We are requesting a price reduction of £14,750 to reflect the cost of bringing the property to the condition assumed at the agreed price."
Frame every request around the cost of repair, not the emotional impact. Sellers and their agents respond to numbers, not feelings.
Step 5: Make the Request Through Your Solicitor or Estate Agent
Don't approach the seller directly — this can inflame emotions and bypass professional channels. Your estate agent is the right conduit for most renegotiations. For complex or contentious issues, ask your solicitor to write a formal letter setting out the position.
Time your request carefully. Once your mortgage offer is in place and exchange is approaching, both parties have a strong incentive to compromise rather than lose the transaction.
What Sellers Typically Accept
In our experience, sellers will usually accept a reduction equal to roughly 70–80% of genuine, documented repair costs, especially where they have had time to obtain their own quotes and verify the findings. They are less likely to accept reductions for items they dispute, or for works your surveyor marked as Condition 2 (routine maintenance) rather than Condition 3.
Common Portsmouth Survey Issues and Typical Costs
| Defect | Typical Remediation Cost | Negotiation Priority |
|---|---|---|
| Full roof replacement (terraced) | £8,000–£18,000 | High |
| Rewiring (3-bed house) | £4,000–£8,000 | High |
| Damp treatment & replastering | £2,500–£7,000 | High |
| Structural crack investigation | £500–£1,500 | Medium |
| Central heating replacement | £3,000–£5,000 | Medium |
| Window replacement (whole house) | £6,000–£15,000 | Low–Medium |
| Pointing & render repairs | £1,500–£5,000 | Low–Medium |
When to Walk Away
Sometimes the right answer is to walk away. If the survey reveals active subsidence with no clear remediation path, Japanese knotweed on or adjacent to the site, significant structural failure, or evidence of serious historic flooding — and the seller refuses any meaningful reduction — it may be in your best interests to withdraw. Losing your survey fee hurts far less than being trapped in a property that costs tens of thousands to remediate and is difficult to resell.
What If the Seller Refuses to Budge?
If the seller rejects your request entirely, you have three choices: accept the property at the agreed price (only if you've genuinely budgeted for the works), make a final, lower offer, or withdraw from the purchase. Do not feel pressured to proceed with a purchase you cannot afford to remediate. The estate agent's job is to close the deal — your job is to protect your own interests.
"Most renegotiations after surveys are resolved sensibly when both sides have accurate cost information. The survey report isn't bad news — it's the truth about the property, and the truth is what you need to negotiate from a position of strength." — Sarah Mitchell, RICS Chartered Surveyor, Portsmouth Surveyors UK
