Quick answer
A property survey checks the conditionof the home and highlights defects, risks and likely repairs. It’s commissioned by the buyer (separate from the lender), and the report is for you.
A survey is not the sameas a mortgage valuation. The valuation is for the lender — usually a quick check that the property is worth roughly the loan amount. The survey is the buyer’s deeper look at what state the property is actually in.
The most common UK home surveys are defined by the Royal Institution of Chartered Surveyors (RICS) and come in three levels — Level 1, Level 2, and Level 3 — explained below.
Survey vs mortgage valuation
Both happen around the same time. Both involve someone looking at the property. They do different jobs.
Mortgage valuation
- • Commissioned and paid for by the lender.
- • Confirms the property is worth roughly the loan amount.
- • Often a desktop, drive-by, or basic visit — not a full inspection.
- • Doesn’t flag defects, repairs, or maintenance issues.
- • The buyer usually doesn’t see the report itself.
Property survey
- • Commissioned and paid for by the buyer.
- • Reports on the property’s condition — defects, risks, repairs.
- • Involves a full visit and (depending on level) a detailed inspection.
- • Includes severity ratings and recommendations.
- • The buyer receives the full written report.
First-time buyer mistake to avoid: assuming the lender’s valuation has covered the property’s condition. It hasn’t. If you want to know what state the home is actually in, that’s on you.
What surveyors usually check
Survey scope varies by level and provider, but most surveyors look at all of these visible elements during a typical visit.
Roof and gutters
Tile and slate condition, sagging, missing or slipped tiles, gutter condition, downpipes, flashings around chimneys.
Walls and structure
Brickwork, render, pointing, cracks, signs of movement or settlement, lintels above openings, structural integrity from the visible elevation.
Damp and timber
Damp readings on visible internal walls, signs of rising or penetrating damp, condensation patterns, evidence of woodworm or rot in accessible timbers.
Windows and doors
Frame condition, glazing, seals, signs of warping or rot, draughts, security where visible.
Heating and hot water
Boiler age, type, last service if known. Radiator condition. Hot water performance from the taps. Energy efficiency notes.
Electrics (visible only)
Consumer unit (fuse box) modernity and condition, visible wiring, sockets and switches. Surveyors don't open up walls — they recommend a specialist EICR if concerned.
Plumbing (visible only)
Visible pipework, water pressure from the taps, signs of leaks. Surveyors recommend a plumber's investigation if concerns are flagged.
Insulation and ventilation
Loft insulation depth where accessible, signs of condensation, extractor fans, airflow in bathrooms and kitchens.
Drainage signs
Visible drains and gullies, signs of blockages or smells, surface water around the property.
Outbuildings and garages
Condition of any sheds, garages, or outbuildings included in the sale.
Boundaries and access
Visible boundary lines, fences, gates, and access points. Surveyors flag obvious discrepancies between what's on the ground and what's on the title plan.
General maintenance condition
Overall sense of how the property has been looked after — paintwork, sealants, gardens, communal areas in flats. A useful signal for what's lurking beneath the surface.
Surveyors check what’s visible. They don’t open up walls, lift floorboards, or move heavy furniture. If something looks concerning, they recommend specialist follow-up reports.
Survey levels explained
The standard UK survey levels are defined by RICS and run from basic to detailed. Wording and product names vary slightly between providers, so always check what’s included.
Level 1 — Condition Report
The most basic survey. Focuses on the property's overall condition with traffic-light ratings (green / amber / red) for major elements. Doesn't include valuation or detailed advice.
Often suits: Newer or recently-built homes in clearly good condition where the buyer mainly wants reassurance about basics.
Level 2 — Homebuyer Report
The most common choice for first-time buyers. Covers the same elements as Level 1 with more detail, plus an opinion on the property's condition, defects, and (if requested) a valuation. Surveyor doesn't open up walls or move heavy furniture.
Often suits: Conventional homes (typically 1900s onwards) in apparently reasonable condition. The default for most first-time buyers.
Level 3 — Building Survey
The most detailed survey. Covers everything in Level 2 with deeper investigation of the property's condition, advice on repairs and maintenance, and (if requested) likely costs.
Often suits: Older homes (pre-1900), unusual construction, listed buildings, properties that have been significantly extended, or anywhere the visible condition raises concerns.
For most first-time buyers buying a conventional home in reasonable condition, Level 2 is the default choice. The surveyor or your broker can confirm whether the specific property warrants Level 3 instead.
Common survey issues first-time buyers see
A clean survey is unusual. Most reports flag something — often manageable, sometimes meaningful. Ten of the most frequently raised:
- Damp
Visible damp readings, staining, blown plaster, or musty smell. Causes range from bridged DPC to broken gutters to condensation. Often manageable, but specialist confirmation is sensible.
- Roof wear
Slipped or missing tiles, deteriorating felt, sagging, or aging flat-roof coverings. Roofs are expensive to replace, so age and remaining life matter.
- Old electrics
Pre-modern consumer units, mixed wiring, or visible signs of age. The surveyor will usually recommend a full EICR (electrical installation condition report) by an electrician.
- Boiler / heating age
Boilers older than 12–15 years often need replacing soon. Worth budgeting for in the move-in plan even if the surveyor doesn't flag immediate failure.
- Cracks
Hairline cracks in plaster are normal. Diagonal cracks more than 3mm wide near doors or windows can indicate movement. Surveyor may recommend a structural engineer's report.
- Drainage concerns
Slow drains, surface water, blocked gullies. Sometimes resolved with a clean and rod; sometimes a sign of a more significant issue requiring a drainage survey.
- Poor ventilation / condensation
Insufficient extractor fans, no trickle vents, or visible condensation. Often fixable but worth budgeting for.
- Timber and rot
Visible rot, woodworm, or insect damage in accessible timbers. Localised treatment is usually possible; widespread infestation can be expensive.
- Asbestos risk
Older properties (typically pre-2000) may contain asbestos in artex ceilings, floor tiles, or boiler flues. Surveyors flag the risk; specialist sampling confirms.
- Flat / leasehold building concerns
External communal areas, cladding, lift maintenance, planned major works. The flat itself may be fine; the building around it may not be.
What to do if the survey finds problems
A flagged issue isn’t automatically a deal-breaker. Six steps that turn a worrying report into a calm decision:
- 1. Don’t panic. Most surveys flag something. Severity ratings (often green/amber/red) tell you which issues actually matter.
- 2. Read the severity ratings. A red rating doesn’t always mean a deal-breaker — it means the surveyor wants you to look closer or budget for it.
- 3. Ask the surveyor questions. Most are happy to talk through findings on the phone. Often the conversation is more useful than the report itself.
- 4. Get quotes if needed. For specific issues — boiler replacement, roof work, damp treatment — a couple of quotes turn vague worry into a real number.
- 5. Speak to your solicitor. If the survey raises legal or title questions (boundaries, access, planning), those go via the conveyancing route.
- 6. Decide: proceed, renegotiate, or walk away. Renegotiate where the issue genuinely changes the value or cost. Walk away where the gap is too wide. Proceed where the issue is manageable in your budget.

Questions to ask before booking a survey
Before booking, a five-minute call with the surveyor sets expectations — and helps you choose between providers.
- 1Which survey level do you recommend for this property type and age?
- 2What will and what won't be inspected (e.g. you can't typically see under floors or behind walls)?
- 3Will photos of issues be included in the report?
- 4Can I speak to the surveyor on the phone after the report to ask questions?
- 5How quickly will the report be ready after the visit?
- 6Does the property's age, type, or condition change the level you'd recommend?
- 7Are specialist follow-up reports (electrics, drains, structural) likely to be needed?
FAQs
Quick answers to the questions UK first-time buyers most often ask about property surveys.
Do I need a survey if my mortgage lender does a valuation?+
Almost always yes. The lender's valuation is for the lender — it confirms the property is worth roughly the loan amount. It's often a desktop or drive-by check and isn't a survey of condition. If you want to know what state the property is actually in, you need to commission a survey separately.
Which survey level should a first-time buyer choose?+
Level 2 (Homebuyer Report) is the most common choice for first-time buyers buying conventional homes in apparently reasonable condition. Level 3 (Building Survey) is worth considering for older properties (pre-1900), unusual construction, listed buildings, significantly extended properties, or anywhere the viewing flagged concerns.
How much does a property survey cost?+
Costs vary by property size, location, surveyor, and survey level. Level 2 reports are typically a few hundred pounds; Level 3 building surveys can be more, especially on larger or older properties. Always get a written quote before booking.
Can a survey reduce the price?+
It can. If the survey reveals significant defects or repair costs, buyers often go back to the seller to renegotiate — either on price, or asking the seller to fix the issue before exchange. The seller can refuse, in which case the buyer decides whether to accept, push harder, or walk away.
What happens if the survey finds damp?+
Most damp is manageable. The surveyor will usually recommend a damp specialist's report, which identifies the cause (rising damp, penetrating damp, condensation, plumbing leaks) and suggests treatment. Once the cause is clear, you can decide whether to renegotiate on price, ask the seller to fix it, or proceed knowing the budget for repairs.
Does a survey check electrics and plumbing?+
Surveyors check what's visible — they don't open up walls, lift floors, or test individual circuits. If they're concerned, they'll recommend specialist follow-up reports: an EICR (Electrical Installation Condition Report) from a qualified electrician, or a plumber's inspection.
Should I get a survey on a flat?+
Yes, the flat itself still benefits from a condition survey. But for leasehold flats, the legal/management side (lease length, service charges, major works) often matters as much as the physical condition. The lease pack and management pack — handled by your solicitor — cover that side.
Can I pull out after a bad survey?+
Yes — until exchange of contracts in England and Wales (and Northern Ireland), either side can withdraw. Many buyers use a survey's findings as a reason to renegotiate or walk away. After exchange, withdrawal usually involves losing the deposit and other costs, so survey-led decisions are best made before exchange.
