The short answer
Start with a radon measurement. If the result suggests reduction is needed, get a property assessment, compare written proposals and arrange a follow-up test after installation.
Testing and measurement
A suitable domestic test establishes the indoor radon level before a remedy is selected. You can use a measurement pack from a validated laboratory, or seek help arranging testing for a more complex property.
Mitigation and reduction
Radon sumps, positive ventilation and under-floor ventilation are among the available methods. Suitability depends on the construction and measured level. The objective is to reduce exposure, with the outcome checked by testing.
How our enquiry service works
UK Radon Gas Mitigation is an information and enquiry website run by Better Home Hub Ltd. We collect the details you choose to submit and, with your consent, share them with a specialist who may be able to help. We are not the installer or testing laboratory, and specialists we introduce may pay Better Home Hub a fee.
Choosing a specialist
Ask about experience with similar floor types, previous radon projects, insurance, installation details and follow-up support. Obtain written terms before authorising work. We do not claim that every area has an available specialist or promise a fixed response time.
