Ofcom measures electromagnetic fields (EMF) near mobile phone base stations. We have been taking these measurements for many years, gradually covering more and more locations across the UK.
We take repeat measurements in Belfast, Cardiff, Liverpool and London. Taken under steady environmental conditions, these repeat audits allow us to observe any changes in EMF emissions over time.
Our measurements have shown that EMF levels are well within the general public EMF limits. Here you can find a test report for each location we have visited.
Older requests can be found at the National Archives.
