A Bad House Survey Report: What To Do Next

What counts as a bad house survey report

A bad house survey report usually means one of two things. Either the surveyor has flagged serious defects, or the valuation has come in below the price you agreed. Sometimes both.

Serious defects are the items rated as urgent or in need of further investigation. On a RICS Home Survey these carry the highest condition rating: think active damp, movement in the structure, a failing roof, timber decay, or something like Japanese knotweed. These are the findings that make people stop and reconsider.

A down valuation is a different problem. Here the property may be sound, but a surveyor's opinion of its market value is lower than the sum you offered. That affects your mortgage and your budget rather than the fabric of the building.

Either way, take a breath. The report has done its job. You now know something you did not know at the viewing, and you have time to deal with it before you are committed.

The red rating is the one that empties the room. A buyer sees it and the words that follow barely register, they have already decided the sale is off. More than once I've had a call within the hour, half convinced they should walk. Then we go through what the rating actually covers, whether it looks active or long settled, and what sits behind it. Nine times out of ten the shoulders drop. A high rating flags something worth a closer look, it does not tell you the house is a write-off. Context does most of the settling.

Read the report carefully, all of it

Start with the summary, but do not stop there. The detail behind each rating is where the useful information sits.

Look at what the surveyor actually says about each defect. There is a difference between "appears to be historic and stable" and "is likely to be active and worsening". One may need monitoring; the other needs work. The wording matters.

Separate the report into three groups as you read:

• Items that are urgent or need further investigation
• Items that need attention but are not urgent
• Routine maintenance and minor points

Most reports contain a long list of minor points. That is normal and not a reason to worry. Focus your energy on the top group. If you are unsure how the ratings work, our guide to RICS condition ratings sets out what each one means.

Ask your surveyor to clarify the findings

You are entitled to ask questions. A good surveyor expects a call after the report lands and will talk you through what they found and why they rated it as they did.

Ask plainly: how serious is this, is it likely to get worse, and what would you do if it were your own purchase. A surveyor cannot give you a repair quote, but they can tell you whether a finding is a monitoring job or a spade-in-the-ground job.

This conversation often changes how a report feels. A finding that reads alarmingly on the page can turn out to be manageable, and a mild-sounding note can turn out to be the one that matters.

I saw a report once where a ceiling was flagged for cracking that read as though the whole thing was coming down. On the phone it was five minutes of work: old lath and plaster, hairline, no movement behind it, the sort of thing you skim and fill. The buyer had been up half the night over it. The reverse happens too. A short line about a "slight" damp reading at skirting level turned out to be a failed injection course across a whole wall, and that one cost real money. Same report, and the words on the page told you almost nothing about which was which.

Get specialist quotes for the issues raised

Before you decide anything, find out what the problems cost to fix. A surveyor identifies and rates a defect. A specialist prices the remedy.

Get at least two quotes for each major item, and choose the right specialist for the job:

• A structural engineer for movement, cracking or subsidence
• A roofer for covering, flashing or chimney defects
• A damp and timber specialist for rot, but read their advice critically
• An electrician for older or unsafe wiring

Be wary of free "damp surveys" from firms that sell the treatment they recommend. They have an interest in finding a problem. An independent view is worth paying for when the numbers are large.

With real figures in hand, a scary report becomes a spreadsheet. You can see whether you are looking at a few hundred pounds or several thousand, and you can plan accordingly.

Use the evidence to decide what happens next

Once you know what the defects cost, you have three routes. The right one depends on the numbers and on how much you want the house.

Renegotiate the price

This is the most common outcome. You go back with quotes and ask for a reduction that reflects the cost of putting things right. Evidence works far better than a round number plucked from the air. Our guide on how to renegotiate an offer after a home survey sets out how to approach it.

Request repairs before exchange

Sometimes it is cleaner to ask the seller to carry out the work rather than reduce the price. This suits well-defined jobs where you want the fix done properly. Get proof the work was completed and, where relevant, a guarantee.

Walk away

If the costs are too high, too uncertain, or the seller will not move, walking away is a legitimate result. A survey that saves you from a bad purchase has paid for itself many times over. The risks of buying without a survey show what you would be exposed to otherwise.

When a down valuation is the problem

If the issue is a low valuation rather than a defect, your options are narrower. Your lender will usually lend against the lower figure, which leaves a gap you have to fund or negotiate away.

You can ask the valuer to reconsider if you have genuine comparable evidence of similar sales nearby, though a revision is not guaranteed. You can renegotiate with the seller to close the gap. Or you can put in more cash if you have it.

It helps to understand that a mortgage valuation and a survey are not the same thing. Our explainer on the difference between a survey and a mortgage valuation is worth a read if the two have become tangled in your mind.

When to commission a further survey or specialist report

Sometimes a report raises a concern without settling it. That is exactly what a "further investigation recommended" note is for. It is not the surveyor hedging: it is a flag that the item sits beyond what a visual inspection can confirm.

Consider a further step in these cases:

• You had a Level 2 survey and it uncovered issues that need the deeper Level 3 inspection
• A structural concern needs a chartered engineer's report
• A damp or timber problem needs an independent specialist rather than a treatment firm
• The property is period, altered or unusual and the general report cannot go far enough

A Level 3 survey looks more closely at construction and defects and gives more detail on repairs and their likely cause. Where a Level 2 has found something and you are unsure how deep it goes, the extra spend can be the difference between an informed decision and a guess.

The theme running through all of this is simple. A bad survey report is not the end of the purchase. It is the point at which you finally have the facts, and facts are what let you negotiate from strength or step away with your eyes open.

Frequently asked questions

Does a bad survey report mean I should pull out?

No. It means you have information you did not have before. Most reports contain some concerns, and many are resolved by renegotiating the price or asking the seller to carry out repairs. Pulling out is one option among several, not the default.

Can I use the survey to reduce the price I agreed?

Yes, and this is common. The strongest approach is to get written quotes for the work the survey identifies and use those figures to ask for a reduction. Evidence carries far more weight with a seller than an unsupported number.

What is the difference between a bad survey and a down valuation?

A bad survey flags defects in the condition of the building. A down valuation means the surveyor's opinion of market value is below your agreed price, which affects your mortgage rather than the fabric of the house. They are separate problems with different solutions.

Should I get a Level 3 survey after a Level 2 raised issues?

Often yes. If your Level 2 survey recommended further investigation on a significant item, a Level 3 survey or a specialist report can confirm the extent and likely cost. It is usually money well spent when a major defect is unclear.

Who do I ask to price the repairs?

Use a specialist matched to the defect: a structural engineer for movement, a roofer for roof issues, an independent damp and timber surveyor for decay, and a qualified electrician for wiring. Get two quotes where the costs look significant.
