The short answer
Both are RICS home surveys, but they sit at different depths. The HomeBuyer survey (Level 2) rates the condition of the main elements and flags defects that need attention, with advice on repairs and maintenance — it suits conventional houses, flats and bungalows in reasonable condition. The building survey (Level 3) goes further: it inspects more thoroughly, including accessible hidden areas, and explains what each defect is, what likely caused it, and what to do about it. It's the right choice for older, larger, altered, extended or unusual properties, or any home where you want a fuller picture. The Level 3 typically costs a few hundred pounds more because it takes longer and produces a more detailed report.
The choice between a HomeBuyer and a building survey is really a choice about how deep an inspection the property needs. Here's how the two compare on the things that matter.

How the two surveys compare
The Level 2 HomeBuyer survey records the condition of the property's main parts with traffic-light ratings, notes defects that may affect it, and advises on repairs and ongoing maintenance — a solid choice for a conventional home in reasonable shape. The Level 3 building survey (once called a 'full structural survey') is the most detailed residential survey: it examines all accessible parts, including spaces such as roof voids and under floors where access allows, and goes beyond condition ratings to explain the cause and implications of each defect and the repairs to consider. The trade-off is time and cost — a Level 3 takes longer on site and produces a longer report.
| Level 2 HomeBuyer | Level 3 Building | |
|---|---|---|
| Depth | condition ratings + advice | deeper inspection + causes & remedies |
| Best for | conventional, reasonable condition | older, larger, altered, unusual |
| Hidden areas | limited | accessible voids inspected where possible |
| Typical cost | ~£400–£1,000 | ~£630–£1,500+ |

How to choose for your purchase
- Modern home in good condition? a Level 2 HomeBuyer is usually enough.
- Older, period or non-standard construction? a Level 3 building survey is the safer choice.
- Extended, converted or visibly altered? Level 3, so the changes are properly examined.
- Planning a renovation? Level 3 gives the detail you'll need to plan works.

Frequently asked questions
What is the difference between a HomeBuyer survey and a building survey?
A HomeBuyer survey (Level 2) rates the condition of the main elements and advises on repairs, suiting conventional homes in reasonable condition. A building survey (Level 3) inspects more thoroughly and explains the cause and implications of each defect, suiting older, larger, altered or unusual properties.
Is a building survey worth the extra cost over a HomeBuyer?
For older, altered or unusual properties, yes — the deeper inspection and detail on causes and remedies can flag issues a Level 2 would only note in passing. For a modern home in good condition, a Level 2 is often enough.
Which survey level should I choose?
Match the level to the property: a Level 2 HomeBuyer for a conventional home in reasonable condition, and a Level 3 building survey for older, period, extended, converted or unusual buildings, or where you want a fuller picture before buying.
