Question 1

What is the radon risk level in TN24?

Accepted Answer

The radon potential in TN24, Kent is classified as Moderate by the British Geological Survey. Approximately 1–3% 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 25 BGS grid squares. Note: some grid squares within TN24 reach class 6, meaning radon risk is not uniform across the district.

Question 2

Do I need a radon test in TN24?

Accepted Answer

Radon levels in TN24 are moderate (1–3% of homes). UKHSA recommends testing if you spend significant time in a ground-floor room or have a basement. A postal radon test kit costs around £29 and takes 3 months.

Question 3

How do I reduce radon levels in my TN24 home?

Accepted Answer

If a radon test in TN24 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 Kent has variable radon levels, targeted remediation is effective regardless of area. Note: parts of TN24 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.
