What this means for you
Your home is very unlikely to have elevated radon. No urgent action is needed. If you're extending your property or converting a basement, a quick test during construction is worthwhile — but for most households here, radon isn't something to lose sleep over.
Even though N7 is in a low risk area, it's worth remembering that radon levels can vary from house to house — even between neighbours. If you'd like certainty, a simple postal test removes all doubt.
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.
