How Much Does a Damp Survey Cost in the UK?

As a guide, an independent damp survey costs £150–£300 for a typical home, rising with property size and depth of investigation.¹ FixQuotes, quoting for landlords, puts the 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 report.²

Why the £150 survey can save you £3,000

A proper survey is a structured investigation: a room-by-room inspection inside and out, recorded moisture readings, the cause established with evidence — distinguishing rising damp, penetrating damp, condensation and leaks, which look alike on a wall and need completely different fixes — and a written report with photographs and recommendations you could hand to a builder, a landlord or a solicitor.¹ If there's no written report with evidence, it isn't a survey — it's an opinion.¹

For landlords the stakes go beyond cost: serious damp can make a property unfit to let under the Homes (Fitness for Human Habitation) Act 2018, and since October 2025 Awaab's Law requires social landlords to investigate significant damp and mould within 10 working days, with powers to extend the duty to private landlords via the Renters' Rights Act 2025.² An evidenced survey report is the document that settles disputes with tenants, freeholders, insurers and builders.
