This guide is intended for school employers, e.g. local authorities, multi-academy trusts; independent, foundation and voluntary-aided schools; standalone academies not in a multi-academy trust; and incorporated colleges.The following list of contractors is not an ‘approved’ list. CLEAPSS has however confirmed that they have worked with schools in the past.A Google(TM) search will suggest further names, but be aware that ‘local’ will not necessarily mean cheaper.Before contacting radon contractors, it is worth checking with the employer’s Health & Safety team and/or site services staff in case they already have links or a contract with a radon contractor.
