HomeBuyer Report vs building survey: which do you need?
The lender’s valuation protects the bank, not you. A survey protects your money. Here’s the difference between RICS Level 1, 2 and 3 surveys, what each costs, and how to choose.

When you buy a home, your lender arranges a valuation - but that only confirms the property is worth roughly what you’re paying. It protects them, not you. A survey is your own inspection, and it’s the cheapest insurance you’ll ever buy against a £20,000 roof.
The three levels of survey
| Survey | RICS level | Cost (typical) | What it covers |
|---|---|---|---|
| Condition Report | Level 1 | £300 – £500 | Traffic-light condition ratings; no detailed advice |
| HomeBuyer Report | Level 2 | £400 – £800 | Condition ratings, urgent defects, valuation, advice on repairs |
| Building Survey | Level 3 | £700 – £1,500+ | In-depth inspection of every accessible element; detailed report |
When to choose each one
Level 1 - Condition Report
A “traffic light” check of the property’s condition with no valuation or repair advice. Fine for a recently built, conventional home you’re happy to take as-is - but for most buyers, the extra £150 for a Level 2 is worth it.
Level 2 - HomeBuyer Report
The default choice for most homes built after ~1900 that look in reasonable condition. You get condition ratings (1–3), the surveyor’s valuation, and clear advice on urgent defects and ongoing maintenance. It flags problems; it doesn’t chase them into every corner.
Level 3 - Building Survey
The full works, for older homes (pre-1900), thatched properties, timber-framed, heavily extended or unusual buildings, or anything you plan to renovate. The surveyor inspects every accessible area in detail - roofs, floors, walls, damp, timbers - and the report runs to dozens of pages. When in doubt on an older property, pay for the Level 3: it’s often cheaper than one surprise.
What surveys actually catch
- Damp and timber issues - the most common findings, and often renegotiable
- Roof condition - a failing roof can cost £5,000–£15,000 to replace
- Subsidence or movement - cracks that signal structural problems (and insurance pain)
- Electrics and heating - ageing installations that will need work
- Japanese knotweed - a nightmare plant that can make a property unmortgageable; the surveyor will flag it
A survey is also a negotiation tool. If it finds genuine defects, you can ask the seller to fix them, reduce the price, or (worst case) walk away. Buyers who skip the survey lose that leverage entirely.
How to book
Your conveyancer or lender can arrange one, or you can find a RICS-regulated surveyor directly. Book it as soon as your offer is accepted - good surveyors get booked up, and waiting costs weeks. The survey runs alongside conveyancing, not after it.
