What to Negotiate After a Bad Survey
Getting a survey back with a list of problems can feel like the purchase is falling apart. In most cases it is not. A survey with findings is actually a useful document, because it gives you specific, documented grounds to go back to the vendor and ask for a lower price. This guide explains how to handle the conversation, what is reasonable to ask for, and what to do if the vendor refuses.
Before you do anything else
Read the survey properly, or have someone help you understand it. A survey full of amber flags does not mean the property is a disaster. Surveyors are required to flag anything that could be a problem, and they tend to err on the side of caution. The section of the report with the highest value to you is the summary of Condition Ratings: anything rated CR3 (urgent) or CR2 (repair needed) is what you are negotiating on.
For CR3 findings, you should get specialist quotes before you approach the vendor. Call a local contractor or specialist, describe the issue, and ask for a written estimate. Even a rough range is useful. For CR2 findings where the cost is not immediately clear, you can either get quotes or use published average costs for that type of work.
The point of this step is to replace vague concern with specific numbers. Telling a vendor that you want a reduction because the roof looks bad is a weak position. Telling a vendor that three roofing contractors have quoted between £9,000 and £13,000 to replace the roof covering is a much stronger one.
What you can reasonably ask for
There are three main outcomes you can ask for, and they are not mutually exclusive:
A price reduction
The most straightforward option. You present the costs from your quotes or the survey itself and ask for the purchase price to be reduced by that amount. This is usually the cleanest outcome because it keeps things simple and gives you the freedom to choose your own contractor after completion.
The vendor fixes the problem before completion
This is worth asking for on significant structural issues where you want certainty that the work is done. The risk is that the vendor uses a cheap contractor, the work is done to a lower standard than you would choose, and you have limited recourse once you have completed. If you go this route, get the work written into the contract and ask for a warranty from the contractor.
A combination
For major issues you can ask the vendor to fix the urgent problem before completion and also reduce the price to reflect the CR2 findings that you will deal with yourself after moving in.
How to approach the conversation
The renegotiation should go through your solicitor in writing, with the survey findings and any specialist quotes attached. Keep it factual and unemotional. You are not complaining about the property. You are presenting evidence that the agreed price no longer reflects the true cost of acquiring and maintaining it.
A typical letter might say: the survey has identified a failed roof covering on the rear extension, requiring replacement at a cost of between £4,500 and £6,000 based on two independent quotes, and significant damp on the north-facing ground floor wall requiring treatment at approximately £1,200 to £1,800. On the basis of these findings, we are asking for a reduction of £6,500 from the agreed price, or for the vendor to carry out the roof replacement under a written contractor warranty before completion.
Give the vendor a clear deadline to respond, typically five to seven working days. You want to keep the transaction moving. Do not make threats about pulling out unless you are genuinely prepared to do so, because an empty threat weakens your position.
What to do if the vendor says no
Vendors refuse renegotiations for a variety of reasons. Sometimes they genuinely cannot afford to reduce the price without being unable to complete their onward purchase. Sometimes they believe their property is worth what you agreed and that survey findings are to be expected in an older home. Sometimes they have another buyer waiting.
If the vendor refuses, you have a decision to make. The key question is whether you would have made an offer at the original price knowing what you know now. If the answer is no, and the vendor is not prepared to move, then you are being asked to complete a transaction on terms that have materially changed since you offered. That is a reasonable basis to withdraw.
If you still want the property and the vendor will not budge, think carefully about what you can afford to spend on repairs in the first two to three years of ownership. If the combined survey findings represent costs you can manage, and you still want the house, you can proceed. But do it with clear eyes, not hope that the problems will turn out to be smaller than the survey suggested.
Before you exchange, ask your surveyor to clarify the urgency of any CR3 findings. Some CR3 ratings are genuinely urgent and will get significantly worse if left. Others are serious but stable. Knowing which category you are dealing with affects how quickly you need to budget for the works after you move in.
Typical findings and what to ask for
Different findings carry different negotiating weight. Here is a rough guide:
| Finding | Typical cost |
|---|---|
| Full roof replacement | £8,000 – £20,000 |
| Flat roof replacement (single extension) | £2,000 – £6,000 |
| Rising damp treatment (per wall) | £500 – £2,500 |
| Penetrating damp source repair | £300 – £5,000 |
| Full rewire | £4,000 – £9,000 |
| Boiler replacement | £1,500 – £4,000 |
| Repointing (partial) | £500 – £3,000 |
| Subsidence investigation and underpinning | £5,000 – £50,000+ |
These are indicative ranges. Get actual quotes for your specific property before presenting a number to the vendor.
