Who Pays for Repairs After a House Survey?

Buyer Guide • House Surveys • Defects & Repairs

Your survey report has come back with a list of defects. Now you want to know: does the seller have to fix them? And if not, who foots the bill?

This is one of the most common questions buyers ask after receiving a house survey. The answer is straightforward, but how you respond to the findings can significantly affect the final price you pay.

This guide explains who is responsible for repairs after a house survey, how to use defect findings to renegotiate, what mortgage lenders may require, and when walking away may be the right decision.

The short answer

Sellers are not legally required to fix anything found in a survey.

Once you complete the purchase, repairs are your responsibility as the new owner.

However, survey findings give you grounds to renegotiate the price or ask the seller to carry out repairs before exchange.

Your options after a survey

Proceed at the agreed price (and budget for repairs yourself)

Renegotiate the price based on repair costs

Ask the seller to fix defects before exchange

Or withdraw from the purchase if the issues are too significant.

Are Sellers Legally Required to Fix Survey Problems?

No. In England and Wales, there is no legal obligation for a seller to carry out repairs identified in a buyer’s survey. The principle of caveat emptor — let the buyer beware — generally applies to property purchases.

This means the seller discloses known issues through the property information forms, but they are not required to fix defects that a buyer’s surveyor identifies. If you proceed to exchange and then complete, all repairs become your responsibility.

Important distinction: A seller has a duty to disclose known material defects on the property information forms (TA6). They must not actively conceal defects. But they do not have to fix them — and they are not responsible for defects that neither party knew about before sale.

What sellers sometimes agree to

Even though sellers are not legally required to act, many will negotiate when defects are identified. Common outcomes include:

A price reduction to reflect the cost of repairs
Agreement to carry out specific works before exchange (rare, but it happens)
A combination of a modest price reduction and seller-led repairs
No movement on price, but willingness to provide receipts for recent maintenance

When sellers typically refuse

Sellers may decline to move on price or carry out repairs if:

The defects are minor (Category 1) and they feel the price is already fair
They have other interested buyers and are not under pressure to negotiate
The market is strong and the property is attracting competing offers
The defects were already disclosed in the property information forms

In these situations, you face a choice: accept the property as-is and budget for repairs, or withdraw from the purchase entirely.

How to Renegotiate After a Survey

Survey findings are a legitimate basis for renegotiating the purchase price. The key is to be specific and evidence-led. Vague claims that the survey “found problems” are less effective than presenting precise repair quotes.

Step 1: Understand the defect categories

RICS surveyors rate defects in three categories:

Category 1: Minor issues requiring routine maintenance. These are not typically a basis for renegotiation.
Category 2: Significant defects needing repair in the near term. These can support a modest price reduction.
Category 3: Serious defects posing a risk to safety, structure, or habitability. These are the strongest basis for renegotiation or withdrawal.

Step 2: Get specialist quotes

For Category 2 and Category 3 defects, commission specialist reports and quotes before approaching the seller. For example:

Damp specialist: £150–£400 for a survey; treatment quotes will give you hard numbers
Structural engineer: £400–£800 for a report on significant cracks or movement
Roofer: Most will provide a free assessment and quote
Timber specialist: £150–£400 if dry rot, wet rot, or woodworm is suspected

Armed with a quote — say, “structural repairs will cost £6,000 based on a structural engineer’s assessment” — you have a clear, documented basis for asking for a price reduction of that amount.

Step 3: Make a specific, reasonable request

Keep the negotiation professional. Approach through your solicitor or estate agent. Provide the quote as evidence and state the reduction you are seeking.

Sellers respond better to specific, evidence-backed requests than to general pressure. “The survey found damp — we’d like £5,000 off” is weaker than “The specialist damp survey confirmed rising damp requiring DPC treatment at a cost of £4,800 — we’d like to reflect that in the price.”

Timing matters: You have the strongest negotiating position between exchange and completion — but acting quickly is important. Sellers may have other interested buyers, or the mortgage offer may have a time limit. Once you exchange contracts, you have committed to the purchase at the agreed price.

Common Repair Costs: What to Budget

Knowing typical repair costs helps you assess whether a renegotiation makes sense and how much to ask for.

Defect Type	Typical Repair Cost	RICS Category
Roof tile replacement (minor)	£500–£2,000	Category 2
Roof replacement (full)	£5,000–£15,000+	Category 3
Rising damp (DPC treatment)	£2,000–£5,000	Category 2–3
Dry rot treatment	£1,500–£20,000+	Category 3
Structural crack investigation & repair	£2,000–£30,000+	Category 2–3
Rewire (full property)	£5,000–£15,000	Category 2–3
Boiler replacement	£2,500–£5,000	Category 1–2
Guttering and fascia replacement	£800–£2,500	Category 1–2
Repointing (partial)	£500–£2,000	Category 2

These are indicative ranges only. Actual costs depend on property size, extent of damage, and regional trade rates. Always get three quotes before finalising a repair budget.

What Your Mortgage Lender May Require

Your mortgage lender will review the survey report and may impose conditions before releasing funds. This is separate from your personal decision to renegotiate — the lender is protecting their security (the property).

Lenders commonly require:

A specialist report for flagged issues (e.g., a structural engineer’s report for major cracks)
Evidence that repairs will be carried out promptly after completion
A retention — the lender holds back a portion of the mortgage until repairs are done
In serious cases, a reduced loan amount if the property value is affected

What is a mortgage retention? A retention is where the lender releases part of the mortgage (say, £5,000) into a solicitor’s account rather than to you at completion. Once you provide evidence of the specified repairs being completed, the retention is released. This is common for roof or structural issues.

If your lender imposes a retention or additional conditions, this strengthens your negotiating position with the seller — you can point to the lender’s requirements as evidence that the defects are significant.

Can You Claim for Repairs the Seller Failed to Disclose?

If a seller actively concealed a defect — for example, painting over damp or placing furniture to hide structural damage — they may be liable for misrepresentation. This is a legal matter and not something to pursue alone.

If you discover after completion that a known defect was deliberately hidden, speak to your solicitor immediately. You may have grounds to claim damages.

However, sellers are not responsible for defects that were genuinely unknown before sale. If rising damp only becomes visible after you move in because the cause (a blocked drain) was hidden, that is unlikely to be a misrepresentation claim unless the seller had prior knowledge.

When Should You Walk Away?

Walking away from a purchase is never an easy decision, especially if you have already spent money on surveys, solicitors, and mortgage applications. But sometimes it is the right call.

Consider withdrawing if:

Category 3 defects are extensive and repair costs would significantly exceed the value you expected to gain
The seller refuses to negotiate at all despite serious structural or damp issues
Your mortgage lender has refused to lend on the property in its current condition
Specialist investigations reveal far more serious problems than the survey indicated
The timeline for specialist investigations and remedial work cannot be managed before your mortgage offer expires

Before exchanging contracts, you are still free to withdraw. You will lose any money spent on the survey and solicitor’s costs to date, but you will not be legally committed to the purchase.

Once you exchange contracts, withdrawing is much more costly — you could lose your deposit and face a damages claim from the seller. This is why it is critical to use the window between survey and exchange to resolve outstanding concerns.

A practical perspective: Every property has some defects. Category 1 issues are normal in older homes and are not a reason to withdraw. The question is always whether the overall picture — price, condition, repair cost, and your lender’s requirements — adds up to a sensible purchase.

Using a Specific Defect Report After Your Survey

If your survey flags one particular concern — a crack, suspected damp, or a roof problem — but you do not want to commission a full specialist investigation immediately, a specific defect report may help.

A specific defect report focuses on a single identified issue. It gives you a professional assessment of the problem, its likely cause, and a recommendation for how to address it. This can be a practical and cost-effective way to understand the risk before committing to a price reduction or a full remediation programme.

Your surveyor can advise on whether a specific defect report is the right next step or whether a specialist (structural engineer, damp specialist, timber specialist) would be more appropriate for the issue identified.

Frequently Asked Questions

Do I have to tell the seller what my survey found?

No. Your survey is commissioned for your benefit and is not shared with the seller automatically. However, if you want to renegotiate based on the findings, you will typically need to share relevant sections to justify your request. Your solicitor or estate agent can advise on how to handle this.

Can the seller pull out if I try to renegotiate?

Yes. Until exchange of contracts, both parties can withdraw for any reason. A seller who feels a renegotiation is unreasonable may decide to relist the property. This risk is real, which is why a measured, evidence-based approach to renegotiation tends to be more effective than aggressive demands.

What if the seller says the defects were already reflected in the asking price?

This is a common response in negotiations. If the property was priced below comparable properties in better condition, this argument may have some merit. However, if specific Category 2 or 3 defects with significant repair costs were not disclosed before the offer was made, you still have a reasonable case for a price adjustment.

Should I use a different surveyor for the specialist investigation?

Not necessarily. Your RICS surveyor can advise which specialist would be most appropriate. For structural issues, they may recommend a structural engineer. For damp, a qualified damp specialist. For roof damage, a roofing contractor. The key is to use someone qualified and insured for that specific area.

Can I get a second survey if I am not happy with the first?

Yes. You can commission a second RICS survey or a more detailed Level 3 Building Survey if you feel the first inspection did not cover the property adequately. This is more common when buyers upgrade from a Level 2 to a Level 3 survey after initial concerns are raised.

Next Steps After Your Survey

Receiving a survey report with defects is not a reason to panic. Most properties have something to address. The priority is to understand what you are dealing with — what category the defects fall into, what they are likely to cost, and what your lender may require.

From there, you can make a calm, informed decision about whether to renegotiate, proceed as-is, or withdraw.
