Electric and magnetic fields


All electrical installations and equipment produce electric and magnetic fields (EMFs), such as:

  • overhead lines
  • substations
  • underground cables
  • domestic appliances.

We are aware of public concern over the alleged effects of EMF and, together with other companies in the public electricity supply industry, are fully committed to sharing knowledge on the issue.

Heath Protection Agency

The Health Protection Agency (HPA) and the National Radiological Protection Board is the UK body with statutory responsibility for advising government on matters relating to electric and magnetic fields.

We follow exposure levels set and carry out all our activities in accordance with HPA guidance.

Over the last twenty years major research programmes throughout the world have explored the possibility that EMFs could have an adverse effect on health.

To date the general conclusion is that there is no established cause-and-effect link between EMFs and ill health.

We will continue to support and contribute to credible research into this subject.
