Radon Gas Testing Across the UK
Radon is a naturally occurring radioactive gas that can build up in buildings and increase the risk of lung cancer, especially for smokers and former smokers. Because you cannot see, smell or taste radon, testing is the only way to know your level.
The Testing Lab PLC (TTL) provides radon gas testing and monitoring for homes, workplaces and public buildings across England, Scotland and Wales, with clear reports and practical advice on what to do next.
Radon gas testing and monitoring across England, Scotland & Wales
Radon levels vary significantly across the UK, depending on local geology and building design. Some areas have a higher probability of raised radon levels, but any building can be affected.
TTL PLC supports:
-
Homeowners and landlords
-
Employers and responsible persons
-
Schools, healthcare and public sector buildings
-
Commercial and industrial premises
We offer testing programmes from single properties to multi-site portfolios, tailored to your risk profile and regulatory requirements.
What is radon gas?
Radon is a colourless, odourless, radioactive gas formed naturally from the decay of uranium in rocks and soils. It seeps out of the ground and can enter buildings through gaps and openings, such as:
-
Cracks in floors and walls
-
Construction joints and gaps around service pipes
-
Unsealed sumps and drains
Outdoors, radon usually disperses quickly and is not a concern. Indoors, especially in enclosed or poorly ventilated spaces, it can accumulate to levels that increase the long-term risk of lung cancer.
Why radon testing is important
Radon is one of the leading causes of lung cancer after smoking. The risk increases with:
-
Higher radon levels
-
Length of time you are exposed
-
Whether you smoke or have smoked in the past
Testing allows you to:
-
Confirm whether radon levels are low, raised or high
-
Make informed decisions about mitigation or further investigation
-
Demonstrate that you have considered radon risk in your property or workplace
-
Provide reassurance to residents, staff, visitors and regulators
Without testing, radon risk is essentially unknown, regardless of the age or type of building.

When should you test for radon?
You should consider radon gas testing when:
-
Your property lies in a known radon-affected area according to national maps
-
You are buying, selling or letting a property and want to understand radon risk
-
You are an employer or dutyholder responsible for workplaces, schools or public buildings, especially in radon-affected areas
-
You are planning basement conversions or significant changes to building use, ventilation or airtightness
-
You simply want reassurance, even if your area is not obviously high risk
We can help you interpret radon probability maps and decide whether testing is appropriate at your location.

Understanding your radon test results
Radon results are typically expressed in becquerels per cubic metre (Bq/m³) as an average concentration over the test period.
Your report will normally categorise results as:
-
Low – below levels at which action is usually recommended
-
Raised or around reference level – where further consideration or follow-up may be appropriate
-
High – where mitigation measures are likely to be recommended
We explain:
-
What your result means for health risk
-
How smoking or previous smoking affects overall risk
-
What your options are, from monitoring to mitigation
Where buildings are used as workplaces, we also consider employer responsibilities under health and safety law and relevant guidance.
Support if radon levels are high
If radon results come back high or significantly raised, we can:
-
Discuss mitigation options, such as improved ventilation or radon sumps
-
Help you prioritise actions based on level, occupancy and vulnerability of occupants
-
Support planning of follow-up testing once mitigation has been installed
-
Coordinate with trusted specialist contractors where required
Our aim is to make radon risk manageable and understandable, not alarming – giving you a clear set of steps to reduce exposure over the long term.

Our Accredited Testing Services
Dear The Testing Lab PLC,
Many thanks for your prompt and professional asbestos survey report service, I would not hesitate to recommend your company in this regard.
This must be an absolute record for getting a report back, considering the surveyor arrived around 3pm – very well done!
Thank you for the very quick response for the quote and scheduling the survey. There’s never any fuss, and always straight forward. Thanks again.
Thank you for offering such a prompt turnaround for ACM testing and for your courteous service in doing so – I had a nervous client to placate and knowing the report would be back with them in such a short time was very reassuring to them, and for no more than a basic service from the competition!
Bradley, thank you for your efforts at short notice today, please pass on our gratitude to your surveyor Tim who did your company proud!
Thank you very much for the air sampling results – and please accept our grateful thanks for resolving this issue so quickly and for the promptness of the report.
Your analyst, Lee, was very helpful and his suggestions and advice appreciated.
We would have no hesitation in recommending The Testing Lab and will be in touch soon with regards arrangements for a full asbestos survey for the rest of the site.
TTL have been working directly as my analyst for the last 12 months on a very complex asbestos removal scheme, they have achieved all of their KPI’s without fail and on a number of occasions surpassed their SLA in acting for us on planning issues associated with the demolition in regard to contamination which cannot be removed as part of the normal sequence of operation.
There reports are always issued within timescales and they have policed the reports by the Licensed asbestos contractor faultlessly sometimes in very difficult circumstances.
