Radon levels in W2: Westminster

W2 (Westminster) is in radon Affected-Area Class 1 — an estimated less than 1% of homes at or above the radon Action Level. This is a lower-risk band: the UKHSA does not designate it as a higher radon Affected Area, and radon protective measures are not generally required for new homes here.

Radon still varies house by house even in lower-class areas, and only a measurement test gives a specific property's own level. Order a test kit from UKradon.
