Question 1

What is the radon risk level in BS14?

Accepted Answer

The radon potential in BS14, Unknown is classified as Very High by the British Geological Survey. Approximately 5–10% of homes in this area may have radon levels above the UK action level of 200 Bq/m³ — compared to a national average of around 1%. The district covers 22 BGS grid squares. Note: some grid squares within BS14 reach class 6, meaning radon risk is not uniform across the district.

Question 2

Do I need a radon test in BS14?

Accepted Answer

Radon levels in BS14 are high (5–10% of homes). UKHSA recommends that all homes in this area are tested as soon as possible. A test kit takes 3 months and costs around £29 — a small price given the health risks of long-term exposure.

Question 3

How do I reduce radon levels in my BS14 home?

Accepted Answer

If a radon test in BS14 shows levels above 200 Bq/m³, the most effective mitigation is a radon sump — a pipe and fan system installed beneath the floor that extracts radon before it enters the building. This typically costs £500–£1,500 and reduces radon by 80–90%. While Unknown has variable radon levels, targeted remediation is effective regardless of area. Note: parts of BS14 reach radon class 6 — higher than the district average — so risk within the postcode district is not uniform. Improved underfloor ventilation and positive pressure ventilation systems are lower-cost alternatives. See our full guide on how to test and what to do if your levels are elevated.
