Bad House Survey Results and Your Options Before Exchange

Before you exchange contracts, a bad house survey leaves you with four choices. You can go ahead as planned, renegotiate the price, ask the seller to fix the problems or walk away entirely. The sensible order of action is to read the report thoroughly, ring your surveyor to discuss it, get repair quotes from contractors and then decide with your conveyancer.

A house survey cannot fail a property

Many buyers panic when a report arrives filled with red warnings. A property cannot officially fail a survey, but it can be marked poorly with low condition ratings. Surveyors use a traffic light system to score the condition of different parts of the building. A rating of one means no repair is currently needed. A rating of two means there are defects that need repairing or replacing, but they are not considered serious or urgent.

The most worrying issues usually fall under a condition rating 3. The official standard describes this as serious and/or urgent defects, with written quotations for repairs to be obtained before legal commitment to purchase.

In 2024 Home Owners Alliance research, 30 per cent of buyers who had a survey took action because of issues it flagged. Of those buyers, 10 per cent renegotiated the price and 9 per cent got sellers to fix problems. You have options, and a poor rating simply gives you the evidence you need to act.

Understanding your survey level and findings

Choosing the cheapest survey level for an old or altered house is a common error. A Level 1 survey describes condition and flags risks and urgent defects, and suits conventional, newer homes in good condition. A Level 3 survey, still widely called a building survey or full structural survey, is the most detailed. It suits older, larger, altered, unusual or run-down homes, or homes you plan to alter.

A Level 2 survey, still widely called a HomeBuyer Report, suits conventional homes in reasonable condition and adds advice on repairs and maintenance. It comes as a survey only or a survey and valuation.

Surveys are sold at a fixed fee quoted up front. Price is driven by survey level, property value, size, age, complexity and location. Typical 2026 guide ranges, not quotes, are roughly £300 to £450 for Level 1, £400 to £950 for Level 2 and £600 to £1,500 or more for Level 3. Inspections take roughly one to two hours for a Level 1, two to four hours for a Level 2, and four to eight hours for a Level 3. Reports usually follow within about three to ten working days.

Read the report and ring your surveyor

Read the entire document before you make any decisions. A long list of defects does not always mean the house is falling down, because a report describes everything the surveyor can see, and almost every home has something that needs attention.

Not reading the terms of engagement before the inspection causes unnecessary panic. Buyers are sometimes surprised the surveyor did not lift carpets, move furniture or test services like the boiler or electrics. A Level 2 survey is a visual, non-intrusive inspection, meaning the surveyor can only report on what they can see.

Good advice involves matching the survey findings to the reality of buying that specific type of home. When you ring your surveyor, make sure to ask these questions:

• Whether they have experience with that exact property type and the local area.
• Which defects in the report are typical for a house of that age.
• Which problems are severe and require immediate attention.
• Whether they recommend any further investigations by specialists.

Get quotes for the recommended repairs

A surveyor will highlight problems, but they do not usually provide exact costs for fixing them. If the survey shows deficiencies, do more research to find out how serious they are and what it would take to resolve them. You should get quotes from at least two experienced contractors before you make a legal commitment to buy.

Trying to renegotiate without repair quotes rarely works. You need accurate figures from professional roofers, damp specialists or builders. Do not diagnose defects yourself. Never carry out your own structural checks, enter lofts, lift drain covers, or disturb materials that may contain asbestos. Hire professionals to inspect the specific problems the surveyor found.

Ignoring recommendations for further investigation is another risk. If the report suggests a timber and damp check, book one immediately. You need a complete picture of the costs before you return to the seller.

Your options before you exchange contracts

Until contracts are exchanged, the sale is not legally binding. If you make a written offer it is always made subject to contract, so you are not committed before finding out more about the state of the property. An oral offer is never legally binding.

If there is a problem with the house you can renegotiate the sale price to reflect the cost of necessary repairs, ask the seller to fix the issue, or decide not to buy at all. You can also choose to accept the property as it is and pay for the repairs yourself after you move in.

The table below compares these four choices and the general pros and cons of each path.

Any repair quotes you gather will depend on the property and the contractor.

How to ask for a lower house price

If major problems are uncovered you may be able to use the information in the survey to negotiate with the seller. You can ask for a price cut equal to the repair costs or ask the seller to make the repairs before exchanging contracts.

If a survey recommends repairs with an estimated cost, you could use this to justify lowering your offer on the property. Present the written quotes from your contractors to the estate agent. The seller can still say no.

You can read more about how to renegotiate the house price to prepare for this conversation. The seller is not legally required to accept your lower offer. They might agree to cover the full cost, offer to meet you halfway, or refuse to drop the price at all.

When walking away is the sensible call

Sometimes a property requires more work than you can afford or manage. If the seller refuses to drop the price and you cannot afford the repairs, walking away is the safest choice.

Booking too late and delaying exchange forces buyers into difficult positions. If you leave your survey until the last minute, gathering repair quotes will stall the purchase. If the delays become too much for the chain, stepping away might be your only option.

When dealing with a bad survey, buyers often make the same errors. Ensure you avoid these common mistakes:

• Relying entirely on the mortgage valuation instead of commissioning a proper survey.
• Comparing quotes that are for different survey levels or exclude a valuation.
• Trying to renegotiate the house price without written repair quotes.
• Starting party wall work without serving notice, which can lead to an injunction.

What happens to your costs if you pull out

At exchange of contracts both you and the seller are legally bound. Once contracts are exchanged, if you drop out you are likely to lose your deposit. From having an offer accepted to exchange of contracts can take up to seven weeks.

If a sale falls through before exchange, a holding deposit of usually £500 to £1,000 is repayable. You will not necessarily get everything back. You may already have paid for a valuation or survey.

If the solicitor has started legal work you may also have to pay for the work done. Before instructing a solicitor or conveyancer, ask what charges will be made if the sale falls through before contracts are exchanged.

Tell your conveyancer and your lender

Keep your conveyancer and your mortgage lender informed of any change, including any major defects the survey reveals or a change to the price you are paying.

Relying on the mortgage valuation is a common mistake. A mortgage valuation is not a survey. It is a limited check for the lender's benefit.

Send all contract questions to a conveyancer or solicitor. Surveyors do not give legal advice on contracts, boundaries or disputes. In Scotland the seller provides a Home Report before marketing, which includes a Level 2 survey and valuation, so the rules described here apply to England and Wales only.

Rules for party walls and property alterations

If your bad survey highlights a boundary issue or a shared wall in poor condition, and you plan to alter it, you must follow the law. The Party Wall etc. Act 1996 applies in England and Wales only. A building owner must give written notice before building on or at the boundary, working on an existing party wall or structure, or excavating near a neighbour's foundations.

Notice is at least two months ahead for party structure works and one month for new boundary walls and excavations. The neighbour has 14 days to respond, and silence counts as a dispute. In a dispute the owners appoint one agreed surveyor or one each, who produce a party wall award. You cannot act as your own surveyor.

The building owner usually pays all surveyors' fees where the work is solely for their benefit. An award can be appealed in the county court within 14 days.

How to check your surveyor is regulated

If you are worried your surveyor missed something or provided a poor report, check their credentials. Look for AssocRICS, MRICS or FRICS after a surveyor's name and the words RICS Regulated for the firm. You can confirm both on the RICS Find a Surveyor service.

RICS regulated firms must have a complaints handling procedure, give consumers free access to an independent alternative dispute resolution provider, and hold professional indemnity insurance. The RPSA is another recognised body for residential surveyors with its own survey products.

Under the Consumer Rights Act 2015 a service must be carried out with reasonable care and skill. Services arranged online or by phone normally carry a 14-day cooling-off period, but if you ask for the work to start inside it you pay for what has been done.

Common questions

Can the seller refuse to lower the asking price?

Yes, the seller can say no. If they refuse, you must decide whether to pay the original price or walk away. Ask your conveyancer or solicitor about your position.

Should I share my survey report with the seller?

If you ask for a price reduction based on the survey, the seller or estate agent will usually want to see the relevant findings and your written repair quotes. Ask your conveyancer before you share the report.

Does a bad survey mean I cannot get a mortgage?

A mortgage valuation is a separate check for the lender and is not a survey. Keep your lender informed of any change, and ask your conveyancer how the survey findings affect your mortgage.

What if the property is a newly built home?

New-build buyers may use a snagging survey instead of a standard home survey. This is a different kind of inspection from a standard home survey.

How are surveys priced if I need a different level?

Surveys are sold at a fixed fee quoted up front. Price is driven by survey level, property value, size, age, complexity and location. Get two or three like-for-like quotes that state the level, whether a valuation is included and the turnaround time.

Your next steps

Before you make any final decisions about the property, work through this checklist.

• Read the entire survey report carefully and note down every condition rating 3.
• Ring your surveyor to discuss the findings and ask how serious the defects are for that specific property type.
• Contact at least two experienced contractors to get written quotes for the recommended repairs.
• Present these quotes to the estate agent if you decide to ask the seller for a price reduction.
• Update your conveyancer on your decision so they can handle the legal paperwork.

Taking action quickly gives you the best chance of keeping your house purchase on track, and when you are ready to proceed or if you need a professional to look at a different property, you can find a surveyor near you.
