A house survey is an independent inspection of a property's condition, arranged by the buyer before exchange of contracts. There are three RICS-defined levels in the UK: a Level 1 Condition Report, a Level 2 Home Survey, and a Level 3 Building Survey. Inspections take a few hours, and reports typically arrive within three to ten working days depending on the level chosen.
What is a house survey and do I actually need one?
A house survey is an inspection carried out by a qualified surveyor to assess the physical condition of the property you're buying, arranged by you as the buyer and completed before exchange of contracts. It isn't a legal requirement in England and Wales, but it's strongly recommended for every purchase. Your mortgage lender will also arrange a valuation, but that's purely to confirm the property is adequate security for the loan, not a check on its condition, so it shouldn't be treated as a substitute for a proper survey.
What's the difference between the three survey levels?
A Level 1 Condition Report gives a basic traffic-light summary of condition and suits newer, conventional properties. A Level 2 Home Survey, the most commonly chosen option, gives a more detailed assessment of visible defects and maintenance requirements, and in some versions includes a market valuation. It suits most conventional properties in reasonable condition. A Level 3 Building Survey is the most comprehensive, covering construction, defects and their causes, repair options and estimated costs, and is recommended for older, unusual or heavily altered properties.
| Survey level | Best for | Typical inspection time | Typical report turnaround |
|---|---|---|---|
| Level 1 (Condition Report) | Newer, conventional properties | 1 to 2 hours | A few working days |
| Level 2 (Home Survey) | Most conventional properties in reasonable condition | 2 to 4 hours | 3 to 5 working days |
| Level 3 (Building Survey) | Older, unusual or heavily altered properties | 4 to 8 hours | Up to 10 working days |
How long does a survey take, start to finish?
The inspection itself typically takes between two hours and a full day, according to RICS, depending on the level and the size of the property, with the surveyor examining accessible areas including walls, roofs, lofts and the exterior. The written report then takes longer to arrive, and turnaround is set by the individual surveyor rather than a fixed industry standard: a Level 2 report is commonly back within three to five working days, while a more detailed Level 3 report often takes closer to ten working days, sometimes longer for an unusually complex property. It's worth asking your surveyor for their expected turnaround before you instruct them.
Why does a survey matter if I've already had a good viewing?
A survey protects you by identifying issues that simply aren't visible during a normal viewing, structural movement, damp, roof defects, drainage problems or substandard building work among them. Buyers who skip a survey altogether can face significant unexpected repair costs after moving in. Finding a problem before exchange gives you options: you can renegotiate the price, ask for repairs to be completed, or in more serious cases decide not to proceed at all.
What happens if the survey finds a problem?
If the survey flags something significant, the buyer will typically raise it in negotiation, requesting either a price reduction or for the seller to complete works before completion. As a seller, it's worth preparing for this possibility. It's a normal part of the process and doesn't necessarily mean your sale is in difficulty. As a buyer, instruct your survey promptly once your offer is accepted, since surveyors can have limited availability and any delay here pushes back your whole timeline.
Frequently asked questions
- Is a house survey a legal requirement in England and Wales?
- No, but it's strongly recommended. Your lender's valuation only checks the property is adequate loan security, it isn't a survey of condition.
- What's the difference between a Level 2 and Level 3 survey?
- Level 2 suits conventional properties in reasonable condition. Level 3 is far more detailed and recommended for older, unusual or heavily altered properties.
- How long does it take to get a survey report back?
- Typically three to five working days for a Level 2, and closer to ten working days for a more detailed Level 3, though this varies by surveyor.
- What happens if a survey finds a problem?
- The buyer can renegotiate the price, ask for repairs before completion, or in serious cases withdraw. This is a normal part of the process.
