The short answer
A 'full structural survey' in the UK usually means the RICS Level 3 Building Survey, which typically costs £600–£1,500+, with most standard houses around £700–£1,200. Price is driven by the property's size, age, condition and location: a small modern home sits near the bottom, while a large, old or altered property — or one in London and the South East — pushes towards or beyond the top, sometimes £2,000+. This fee buys a thorough visual inspection and a detailed report covering structure and the whole property, with defects explained. If the survey reveals a specific structural problem — cracking, subsidence, a removed support — a separate structural engineer's report may be needed, typically adding £200–£800+ depending on the complexity. The survey fee does not include that engineer's report, specialist tests, or a valuation.
The phrase 'full structural survey' predates the current RICS naming, so the cost is really the cost of a Level 3 Building Survey — plus any specialist follow-up it triggers.

What you are really paying for
When people ask about a 'full structural survey', they almost always mean the most detailed mainstream survey, which today is the RICS Level 3 Building Survey. It is a comprehensive, visual, non-disruptive inspection of the whole property — structure, roof, walls, floors, services, damp and timber — with a detailed report that explains the cause and consequences of each defect and rates them with the traffic-light system. The fee reflects the surveyor's time on site (several hours for most homes) and the longer, tailored write-up.
| Property | Typical cost | Notes |
|---|---|---|
| 1–2 bed flat or terrace | £600–£900 | Smaller, simpler structure |
| 3-bed semi or terrace | £700–£1,100 | Most common bracket |
| 4-bed detached | £900–£1,500 | More to inspect |
| Large / period / unusual | £1,400–£2,000+ | Complex construction |
| + Engineer's report | £200–£800+ | Only if a defect needs it |

What moves the price
Two superficially similar homes can carry different fees. The main drivers are:
- Size: more floor area, more roof and more rooms means more inspection time.
- Age: period and pre-1900 homes take longer to read and tend to cost more.
- Condition: a neglected property generates more findings and a longer report.
- Alterations: extensions, loft conversions and knock-throughs add elements to assess.
- Construction type: timber frame, thatch, stone or non-standard cavity needs specialist reading.
- Region: London and the South East sit clearly above much of the rest of the UK.
When a structural engineer adds to the bill
A Level 3 survey assesses structure as part of the whole property and will flag signs of movement, subsidence, roof spread or unsupported alterations with a red rating. What it does not do is provide the specialist diagnosis and calculations that a defined structural problem sometimes needs. Where the survey recommends it, a chartered structural engineer is instructed separately.
Frequently asked questions
Is a full structural survey the same as a building survey?
In everyday use, yes. 'Full structural survey' is the old name for what is now the RICS Level 3 Building Survey. A true structural engineer's report is a different, narrower instruction focused on one specific structural defect.
Does the survey cost include a structural engineer's report?
No. The Level 3 fee covers the surveyor's whole-property inspection and report. If a specific structural concern is found, a separate engineer's report is instructed and charged on top, typically £200–£800 or more depending on complexity.
Can I get a cheaper survey on an old house?
You can choose a lower RICS level, but it is rarely wise on an older property. A Level 1 or Level 2 will not read period construction and defects as thoroughly, so any saving risks missing costly issues a Level 3 would have explained.
