Ofcom regulates the operation of mobile networks in relation to their use of radio frequencies but does not have any duties related to the recommendations for exposure to EMF emissions. We have published an information page about exposure to electromagnetic fields which provides background information and indicates where further advice may be found.
Ofcom covers a very wide range of topics in the spectrum, telecommunications, broadcasting and postal policy areas. A great deal of information, advice and FAQs is published on our website. But if you do not find the information you need, please visit contacting Ofcom or call us on 0300 123 3333 or 020 7981 3040. We are open Monday to Friday from 9.00am to 5.00pm.
The Sitefinder website has now been discontinued.
We no longer receive data updates from mobile operators on their mast locations. As a result, the Sitefinder data was several years old and could be very misleading.

It therefore does not represent current network deployment. It is still available to download for reference, although Ofcom does not accept any liability for inaccuracies or omissions in the data.
Between 2001 and 2012, Ofcom and its predecessor, the Radiocommunications Agency (RA), conducted a programme of measurements showing that emission levels around mobile phone base stations were consistently found to be only a very small fraction of the safety levels for exposure published by Public Health England.
