Water testing for legionella cost UK: what determines the quote?
There’s no reliable headline figure without a defined scope.

Check whether the proposal includes sample collection, transport or other sample handling, laboratory analysis, and reporting, or only some of these.

Questions to ask before accepting a water-testing quote

For a quote based on your requirements, share your testing scope.

Choose a UK legionella testing provider and request a tailored quote
A sound quote starts with a provider that can explain its sampling approach, analysis and reporting in clear terms.

Prepare the information needed for a useful quote
Share the site location, a brief description of the water system, why testing is being considered, and any known sampling requirements or locations. If you already have a risk assessment or defined sampling plan, mention it. If you’re unsure whether testing or a broader assessment is appropriate, explain that too, so the provider can clarify the scope rather than price an assumed service.
For broader compliance context, read the Legionella risk assessment guide. A risk assessment evaluates system risks; laboratory testing analyses water samples. The two address different needs.
