Electric and magnetic fields (EMFs) can be generated from a wide variety of sources, including our distribution and transmission power lines.

We take seriously the issues that surround electric and magnetic fields. We recognise that there is scientific uncertainty as to whether the electric and magnetic fields that are produced by some of our assets have an effect on health or not, and that this produces public concern. We monitor the science carefully but we look to relevant independent bodies such as the World Health Organization and the UK’s Health Protection Agency for authoritative advice. In all our operations, as a minimum, we aim to comply with the relevant regulations, guidelines or practices in force in the different jurisdictions in which we operate.

In addition, we actively support high-quality research and open communication (including maintaining a website at www.emfs.info) and we look for more constructive and less confrontational ways of handling this issue.

All these activities are governed by our public position statement on electric and magnetic fields, which we review annually.
