UK Power Networks Fined After Employee Does On Essex Site

UK Power Networks (Operations) Ltd, which supplies power to the East of England, London and the South East, has been ordered to pay £420,000 in fines and costs after an employee died while working at one of its Essex sites.

Electrical engineer John Higgins, 59, from Colchester, was killed at an electrical substation in Bishops Hall Lane in Chelmsford on 7 May 2008 when a device he was working on for manually adjusting voltage ratios, known as a transformer tap changer, exploded.


Chelmsford Crown Court heard that the explosion caused a fire at the substation. Mr Higgins died at the scene despite the arrival of Essex Fire and Rescue within minutes of the alarm being raised by staff from nearby Anglia Ruskin University.

The incident also blacked out a large part of Chelmsford, including Broomfield Hospital.

An investigation by the Health and Safety Executive (HSE) found that UK Power Networks had failed to properly assess work with tap changers and to devise procedures for the work. It had also failed to adequately train employees for carrying out this task.

UK Power Networks has since introduced revised procedures to safeguard staff.

UK Power Networks (Operations) Limited, of Newington House, 237 Southwark Bridge Road, London, was fined £275,000 with £145,000 in prosecution costs after pleading guilty to breaching Section 2(1) of the Health and Safety at Work etc. Act 1974.
