Your survey has come back with some significant findings. Maybe there's a roof that needs replacing, or damp behind the kitchen units, or cracks that suggest historic subsidence. Your first instinct might be to panic — or worse, to simply proceed without acting on the report. Both would be mistakes.
A survey with significant findings is actually your strongest negotiating tool in the property transaction. Here's how to use it effectively.
Step 1: Understand What You're Dealing With
The first thing to do is have a proper conversation with your surveyor. At Paddington Surveyors, we call every client after delivering a report for exactly this reason. You need to understand:
- Which findings are genuinely significant and which are normal maintenance items
- Whether any Condition 3 items require specialist investigation before you can assess the true cost
- The realistic cost range for repairing the significant defects
- Whether any issues are likely to affect your mortgage offer or ability to get buildings insurance
Don't rely on your own interpretation of a survey report without speaking to the surveyor. The report is written for a professional audience and nuances are easily missed.
Step 2: Get Repair Cost Estimates
Before you approach the vendor with a renegotiation, you need substantiated figures. A surveyor's rough estimate in the report is a starting point, but for significant items — a new roof, dry rot treatment, structural underpinning — you want contractor quotes or at least specialist assessments.
We can provide estimated cost ranges within the report or as a separate addendum. For complex structural matters, we may recommend you instruct a structural engineer. For dry rot or timber treatment, an independent timber specialist (not a treatment company with a commercial interest) is the right source.
Step 3: Choose Your Strategy
You have four main options:
- Price reduction: Ask the vendor to reduce the purchase price by an amount reflecting the cost of remediation. This is the cleanest approach — you take control of the works yourself and choose your own contractors.
- Vendor remediation: Ask the vendor to carry out the works before completion. This can work for straightforward defects but carries risks — the vendor may use cheap contractors, and you'll need to inspect the works before exchange to confirm they've been done properly.
- Retention: A sum of money is held back from the purchase price and released to the buyer after specified works are completed post-completion. This is less common in residential transactions but can work where agreement can't be reached on cost.
- Walk away: If the findings are sufficiently serious — and the vendor won't negotiate at all — walking away is a legitimate and sometimes correct response. It's far better to lose a survey fee than to complete on a property with £50,000-worth of undisclosed defects.
Step 4: Frame the Conversation Carefully
The way you approach the renegotiation matters. Don't frame it as "I've found all these problems with your house." Instead, frame it as "My survey has identified some issues that were not apparent on a visual inspection. I still want to proceed, but I need the price to reflect the cost of remediation."
Put your request in writing — ideally through your solicitor — with the specific items you're referencing and the basis for the figure you're requesting. A surveyor's report is objective professional evidence; use it as such.
What Results Can You Expect?
In our experience, price reductions based on survey findings are achieved in the majority of cases where significant defects are identified and properly substantiated. The average reduction we see in Central London is between £5,000 and £25,000, depending on the severity of the issues. For major structural or damp problems, reductions of £30,000–£60,000 are not unusual.
