Radon is present everywhere, but high levels are more likely in designated radon Affected Areas. Use the official UK Radon Map to check your risk.

Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil and rocks. It can accumulate indoors and pose health risks.

Radon enters through cracks in floors, walls, gaps around pipes, and other openings in the building’s foundation.

Radon mitigation systems reduce radon within days, with full benefits verified after a three-month follow-up test as recommended by UKHSA.

Basic ventilation improvements may be DIY, but sump and PIV installations require professional expertise to ensure safety and compliance.

Yes. Sumps suit solid floors, under-floor ventilation works for suspended floors, and PIV is beneficial for both. UKHSA and BRE provide official guidance for all property types.

Sump systems typically cost £1500–£3000. PIV installations range from £1600–£2500. Running costs are low and systems are designed for energy efficiency.
