Even though privatisation has meant that we're able to choose whichever company we wish for our energy, many people still seem to have an affinity for their historically linked supplier. Chelmsford is a great example, seeing the most popular supplier, locally, being EDF Energy.

Before 1989, the electricity supply in Chelmsford was supplied by 'Eastern Electricity Board'. Thereafter it became 'Eastern Electricity'. It was acquired by 'Hanson plc' in 1995 and then again by 'Texas Utilities' from the US. After this, it was acquired by 'Powergen', which was a large step towards its current state. The supply is now part of E·ON and the distribution, that was part of EDF Energy, is now part of UK Power Networks.


Chelmsford used to be supplied by 'Eastern Gas Board' before 1973; however, it thereafter became a region of the British Gas Corporation.
