Q: Do I need a radon test in L49?

Radon levels in L49 are generally low (<1% of homes may be above the action level). Most homes will not require a radon test, but if you are extending your property, installing underfloor heating, or live in an older home with poor ventilation, a test is inexpensive peace of mind.

Q: How do I reduce radon levels in my L49 home?

If a radon test in L49 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. 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.
