Radon for home buyers in England and Wales: maps, tests, and proportionate action

Radon is a naturally occurring gas. Public health bodies publish indicative maps and guidance on testing and remediation. For buyers, the goal is proportionate risk awareness, not fear.

What the map does and does not do

A map shows where higher indoor concentrations are more likely on average. It does not measure your living room today. A short-term test kit placed correctly is the practical next step when a property sits in an affected area or when you simply want peace of mind.

Mortgages, insurance, and resale

Most mainstream purchases proceed normally with normal outcomes after testing where needed. Keep records of tests and any remedial work as Documents in your Property Passport for the next buyer.

Linking to other risk layers

Radon sits alongside flood, EPC, and geology questions. A property-centric record helps you see layers without mixing them up.

General information only; follow UKHSA and HSE guidance for testing and remediation.
