Radon information distinguishes an area’s estimated likelihood from the measured level inside a building. If the issue is relevant to your purchase, ask for the evidence about the home itself and use UKHSA’s specialist guidance.
What to check.
Check the official guidance
Use UKradon’s buyer and seller guidance to understand affected-area information and the relevant next steps for the address.
Ask whether testing exists
Request a copy of any measurement report and ask about its date, coverage and subsequent work. A neighbour’s result is not a measurement of this home.
Discuss unresolved results
Ask the relevant professional about testing or mitigation where needed. Keep any further investigation separate from a broad map-based indication.
What the evidence cannot tell you.
HouseDossier does not measure indoor radon or confirm a home’s exposure level. Indicative area information should not be presented as a laboratory result or a medical assessment.
