What this site covers and what it does not

This site, and the EMF helpline, cover power frequency EMFs associated with the UK electricity transmission and distribution industry only. We do not cover any other type of EMFs including radiofrequency fields such as wifi or mobile phones.

Railways and some other electric transport systems produce similar EMFs to the UK electricity industry. This means that much of the material on this website will be relevant to railways as well, but on the helpline, we cannot advise on other utilities infrastructure.

Contacts for other issues

The EMF helpline deals specifically with questions about EMFs and health. If you need other information on National Grid or have other queries, the selection of links below may be of assistance.
