Compare house survey types and costs before you buy

How do I arrange a house survey?

Arranging a survey is straightforward once your offer has been accepted. These five steps cover the process from choosing a surveyor to acting on the results.

1. Decide which survey level you need: Match the survey to your property. A Level 2 survey covers most conventional homes in reasonable condition. A Level 3 building survey gives a more detailed inspection for older, larger or altered properties. If you are buying a new build, a snagging survey checks for construction defects before you move in.
2. Find a RICS-registered surveyor: Use the RICS Find a Surveyor tool or ask your conveyancer for a recommendation. Check that the surveyor carries professional indemnity insurance and has experience with your property type and area. Read our guide to choosing a RICS surveyor.
3. Get quotes and book the inspection: Contact two or three surveyors for quotes. Provide the property address, type, approximate age and the agreed purchase price. Most surveyors can visit the property within one to two weeks of booking.
4. Review the report carefully: Your surveyor will send a written report within three to five working days of the inspection. Read every section, paying particular attention to any items rated condition 3 (serious defects requiring urgent attention). If anything is unclear, call the surveyor to discuss it.
5. Act on the findings: If the survey reveals significant problems, you have three options: negotiate a price reduction with the seller, ask the seller to carry out repairs before exchange, or withdraw from the purchase. Your conveyancer can advise on the best approach based on the severity of the issues found.

What is a house survey?

A house survey is an independent inspection of a property's condition carried out by a qualified surveyor before you commit to buying it. The surveyor examines the building's structure, fabric and services, then produces a written report detailing any defects, potential risks and maintenance issues.

A survey is not the same as a mortgage valuation. Your lender arranges a valuation to confirm the property is worth the amount they are lending you. It protects the lender, not you. A survey protects you by identifying problems that could cost thousands of pounds to fix after you move in.

In England and Wales, getting a survey is not a legal requirement, but it is strongly recommended. In Scotland, the seller must provide a Home Report before marketing the property, which includes a survey element. Around one in five buyers who skip a survey discover problems after completion that they wish they had known about beforehand.

What types of house survey are there?

RICS (Royal Institution of Chartered Surveyors) offers three standardised survey levels, each designed for different property types and buyer needs. Two specialist survey types cover new builds and Scottish properties.

Not sure which level suits your property? Our Level 2 vs Level 3 comparison walks through the decision by property age, construction type and known issues.

How much does a house survey cost?

House survey costs depend on the survey level, property value and your location. London and the South East tend to be 10% to 20% more expensive than the rest of the UK. The table below shows typical 2026 prices by property value band.

These figures cover the surveyor's fee only. You will also pay separately for your conveyancing fees, local authority searches and your lender's mortgage valuation. For a full breakdown of what affects the price, read our detailed house survey cost guide.

A survey is one part of your total upfront buying costs. A typical purchase might involve £500 to £1,500 for the survey, £1,000 to £1,800 for conveyancing, £250 to £450 for searches and £250 to £600 for a mortgage valuation. Budgeting for all of these together gives you a realistic picture of what buying a property actually costs before you exchange.

Which survey level do I need?

Choosing the right survey level saves you money without leaving you exposed to hidden defects. Use this decision framework based on your property's age, construction and condition.

• New build (under 10 years old): A snagging survey is usually more appropriate than a Level 2 or 3. It focuses on construction quality, unfinished work and building regulation compliance. Your NHBC warranty covers structural defects, but snagging catches cosmetic and minor issues the developer should fix before you move in.
• Standard home built after 1930 in reasonable condition: A Level 2 survey is the right choice for most buyers. It identifies significant defects and gives condition ratings for each element, without the cost of a full building survey.
• Pre-1930 property, listed building or unusual construction: A Level 3 building survey is worth the extra cost. Older properties are more likely to have hidden structural issues, non-standard materials and past alterations that a Level 2 inspection would not examine in enough detail.
• Property with known issues or planned renovations: Choose a Level 3 even if the property is relatively modern. If you already know there are damp patches, cracks or previous subsidence, you need the detailed defect analysis and repair guidance that only a Level 3 provides.
• Buying in Scotland: The seller provides a Home Report that includes a survey. You can commission your own independent survey on top of this if the Home Report raises concerns or if you want a more detailed inspection.

What is the difference between a survey and a mortgage valuation?

This is one of the most common points of confusion for buyers. A mortgage valuation and a house survey serve completely different purposes.

A mortgage valuation will not tell you about damp, structural movement, roof defects or any of the problems that could cost you thousands after you move in. For a more detailed explanation, read our full guide to mortgage valuation vs survey.

Do I need a special valuation for Help to Buy or shared ownership?

Yes. If you bought your home through Help to Buy or a shared ownership scheme, you will need a specific RICS Red Book valuation at certain points, not a standard house survey.

Help to Buy valuations are required when you want to repay the government equity loan, sell your property or remortgage. The valuation must be carried out by a RICS-registered valuer and follows Red Book standards. It determines the current market value, which the government uses to calculate how much you owe on the equity loan. Typical cost is £250 to £500. Read our full Help to Buy valuation guide.

Shared ownership valuations are needed when you want to staircase (buy additional shares in your home) or sell. Again, a RICS Red Book valuation is required, and your housing association will specify any additional requirements. Most associations accept the valuation for up to three months after the valuation date. Costs typically range from £250 to £600. Find out more about shared ownership valuations.

What are the most common survey problems?

Surveys regularly uncover issues that buyers would not spot during a viewing. Knowing what to expect helps you react calmly and make better decisions if your report flags concerns.

• Damp and moisture: The most frequently reported issue. Rising damp, penetrating damp and condensation each have different causes and repair costs. Minor condensation may need better ventilation. Rising damp affecting ground-floor walls can cost £2,000 to £6,000 to treat.
• Roof defects: Missing or slipped tiles, damaged flashing, sagging ridge lines and worn flat-roof coverings. Roof repairs range from a few hundred pounds for minor fixes to £5,000 or more for a full re-covering.
• Structural movement: Cracks in walls, floors or ceilings that may indicate subsidence, settlement or heave. Historic movement that has stabilised is far less serious than active, ongoing movement. Underpinning costs can exceed £10,000.
• Timber defects: Woodworm, wet rot and dry rot in joists, rafters and floor timbers. Dry rot is the most serious and can spread rapidly if untreated. Treatment and timber replacement costs vary widely depending on the extent of the damage.
• Japanese knotweed: This invasive plant can damage drains and lightweight structures such as garages and boundary walls, and it can restrict use of a garden. RICS assesses it by its impact rather than by a fixed distance. Where it is damaging a structure or restricting use of the garden, RICS anticipates that most lenders will ask for a specialist inspection and a management plan, but each lender sets its own policy. Treatment typically costs £2,000 to £5,000.
• Electrical and plumbing issues: Outdated wiring, lack of earthing, old lead pipework or visible signs of previous leaks. A full rewire costs £3,000 to £6,000 for a typical three-bedroom house.

What should I do after a bad survey?

A survey that reveals problems does not mean you have to pull out of the purchase. In many cases, the findings give you leverage to negotiate a better deal. Follow these steps to decide your next move.

1. Separate serious from cosmetic issues: Condition 3 ratings (serious defects needing urgent repair) are the items that matter most. Condition 2 items (defects needing attention but not urgent) are normal in most properties and rarely justify a price reduction on their own.
2. Get repair cost estimates: For any serious defects, ask a specialist contractor for a written quote. A surveyor's estimated repair cost gives you a starting point, but a builder's quote carries more weight in negotiations with the seller.
3. Negotiate a price reduction: Present the evidence to the seller's estate agent: the surveyor's report plus contractor quotes. Most sellers expect some negotiation after a survey. A reasonable approach is to request a reduction equal to the repair cost, then settle somewhere in between.
4. Ask the seller to fix issues before exchange: For specific defects like a leaking roof or faulty boiler, you can ask the seller to carry out the repair and provide evidence of completion before you exchange contracts.
5. Walk away if the risk is too high: Active subsidence, severe structural defects or extensive Japanese knotweed may make the purchase too risky at any price. You will lose your survey fee and any conveyancing costs incurred so far, but that is far less than the cost of inheriting a serious structural problem.

Our full guide to negotiating after a survey covers what to say, how much to ask for and when walking away is the right decision.

Where does a survey fit in the conveyancing process?

Your survey is one of several checks that happen between having your offer accepted and exchanging contracts. Understanding the timeline helps you avoid delays and coordinate with your conveyancer.

1. Offer accepted: Instruct a conveyancer and a surveyor at the same time. Both processes run in parallel, so starting both promptly keeps the transaction moving.
2. Survey and searches happen together (weeks 2 to 4): Your surveyor inspects the property while your conveyancer orders local authority searches, environmental searches and drainage checks. Neither depends on the other, so there is no need to wait for one before starting the other.
3. Survey report arrives (weeks 3 to 5): Review the report with your surveyor. If it reveals significant issues, negotiate with the seller before your conveyancer moves to the next stage. This is the cheapest point to walk away if the problems are too serious.
4. Mortgage offer confirmed (weeks 4 to 6): Your lender issues a formal mortgage offer after their valuation. This is separate from your survey. If the survey found issues that affect the value, your lender may reduce their offer or add conditions.
5. Exchange of contracts (weeks 6 to 12): Once searches are clear, the survey is satisfactory and your mortgage offer is confirmed, your conveyancer prepares for exchange. After exchange, you are legally committed to the purchase.
