Scottish & Southern Energy says it is to cut prices for the first time in six years.  The group, which supplies energy as Southern Electric, Swalec, Scottish Hydro Electric and Atlantic Electric and Gas, expects to cut gas and electricity tariffs within the “next few months”.  The firm currently has seven million domestic customers; it increased its prices at the start of January, when electricity bills rose by an average of 9.4% and gas by 12.2%.  The move, announced in September, came about because of three years of sustained wholesale price hikes.  “Since last September, we have made clear our intention to cut gas and electricity if there was a sustained fall in wholesale prices which would allow us to do so,” said director Alistair Phillips-Davies.  “I am very pleased that we have now been able to confirm this.  “We are now monitoring costs and evaluating how we will be able to pass savings on to customers.”  Warm weather and increased imports from overseas have seen wholesale prices more than halve since the summer.  British Gas owner Centrica recently pledged to cut prices in the spring after seeing nearly one million customers leave the firm in the wake of price rises last year.
