Contacting us about EMF and health issues
Please note: we welcome international users of this website, and try to provide content relevant to other countries where appropriate, but our email and telephone helpline are for UK users only. Sorry!
This website is run by National Grid on behalf of the UK electricity industry. You can send comments on this website or ask questions or make enquiries of the National Grid EMF Helpline by contacting us by one of the following ways:
- telephone (please use whichever number is cheaper for you):
- 0845 7023270
- 01926 653382
- email: EMFHelpline@nationalgrid.com

Prior to making any inquiry please use the information provided on this website to see if this can give you the answers you need; however, if you still have questions, then please feel free to contact us.
For all queries please remember to include your name, the UK post code and address relating to the query, brief details of the background to the query and the information you need, and an email address or a daytime phone number as appropriate. If you do not provide all of the information this may lead to significant delay on replying to your query.
Although we cannot promise to reply immediately we will return your email or phone call as soon as possible.
What we cover and what we don't
This site, and the Helpline, cover power frequencies, not radiofrequencies. We do give some information on radiofrequencies but we don't deal with those on the Helpline.
We cover the UK electricity industry. The railways and some other electric transport systems also produce similar EMFs. This means that much of the material we provide here will be relevant to railways as well. But, sorry, on the Helpline we can't deal with issues that originate from that industry.
