What this means for you
At this risk level, UKHSA recommends every home is tested. The good news: even if your result is elevated, effective mitigation options exist from around £300. The important thing is to test — radon is fixable, but only if you know it's there.
Seasonal factors
Radon levels tend to be higher in winter when homes are sealed up and ventilation is reduced. If you're planning a test, autumn or winter is the best time — your result will reflect a more realistic worst-case scenario. Summer tests may underestimate your true annual exposure, since open windows dilute indoor radon. The standard 90-day postal test is designed to average out daily fluctuations and give a reliable reading.
