Damp Survey Cost Guide (UK, 2026)
Price data verified 2026-10-10
This page collects every published UK damp survey price we can verify, with the source and verification date behind each figure. As a headline: independent damp surveys are typically quoted at £150–£300 for a typical home1, with landlord-focused guides putting the full independent range at £150–£400+, from a focused inspection of one problem wall up to a whole-house investigation with moisture readings and a written report2.
Every published price point, by property and scope
One universal price doesn't exist: fees move with the size of the property, the extent of the suspected damp, how detailed the report needs to be, and where the property is8.

What moves the price
London and the South East typically run 10–20% higher than other regions for damp surveys. 9
A survey on top of timber decay/infestation inspection (damp and timber survey) sits slightly above a damp-only survey for the same property. 1
Survey depth matters too: a basic walk-round with a moisture meter can be as low as £75–£150, while a PCA-certified forensic report used in disputes runs £400–£600+3. Anything significantly cheaper than the market range usually means missing inspection elements or a treatment upsell3.
When a paid survey is worth it
A damp survey is usually most worthwhile when a general survey has flagged moisture concerns, mould or staining is already visible, the property is older, or you want a clear diagnosis before exchange — damp findings are most useful while you can still renegotiate or walk away. 8
A 'free' damp survey from a company that sells damp-proofing is a sales visit: the diagnosis comes from a party that profits from recommending treatment. 1

| Damp proofing whole ground floor (DPC + basic replastering) | £900 – £1,800 | 12 |
| Average cost of damp proofing a home | £1,250 | 11 |
| Condensation / ventilation fixes (extractors, PIV) | £300 – £1,500 | 5 |

Note that damp proofing quotes usually exclude the survey itself, and a detailed survey can uncover hidden damage that increases the treatment scope11. If a treatment company offers a "free" survey, the diagnosis comes from the party that profits from recommending the treatment1.
