1990 saw the start of the privatisation of the UK Electricity market started.  This paved the way for the full deregulation of the electricity market allowing other companies to supply to regions that were previously unavailable.  There were originally 14 supply areas in the UK, with regional supply companies.  Each of these companies could only supply the customers in their respective regions.  The electricity market opened in two stages.  Firstly companies were allowed to offer products in other supply regions but the regional supplier had to have their pricing agreed by Ofgem before they could change prices.

This was to make sure that companies coming in to new areas provided cheaper products than those of the regional supplier.

After a few years of this the restrictions were lifted to allow regional supply companies to compete in a fully deregulated market.

This deregulation has created a highly competitive market bringing considerable benefits to industrial, commercial and domestic customers.  It has allowed customers the choice of supplier therefore keeping pressure on costs and promoting greater choice of tariffs and services.
