Electric and Magnetic Fields

The question of whether electric and magnetic fields are linked in any way to ill-health is a long standing one which still has no conclusive answer.
ENA and the rest of the energy sector is committed to providing all members of the public and the industry’s employees with full and up-to-date information on the issue.

ENA takes any suggestion of a risk to health extremely seriously. ENA believes that the final decision about what constitutes a safe level of exposure should be made by the Government, advised by the Health Protection Agency.

In 2004, the electricity industry initiated discussions on possible precautionary measures for EMFs. For example it considered possible restrictions on building homes close to power lines - no such restrictions currently exist. These discussions gave rise to the Stakeholder Advisory Group on Extremely Low Frequency EMFs, (SAGE) which included citizen groups alongside industry and Government.

Exposure limits

All UK electricity systems comply with the exposure limits in force in the UK, and, as an additional precautionary measure, with a policy of optimum phasing. The details of these are set out in three Codes of Practice agreed with Government and can be found on the DECC website here.

The industry also publishes detailed evidence of compliance with the exposure limits.

Research

ENA is committed to supporting high-quality independent research to help get closer to a final answer on the EMF issue.
