ScottishPower has reported that it has made significant progress in improving its customer service standards, having achieved the lowest number of recorded complaints made to EnergyWatch since records began in 1999.

The achievement is the result of a major customer service initiative undertaken by ScottishPower Energy Retail, one of the UK’s largest suppliers of gas and electricity with over 5.2 million customers within the UK.

Commenting, chief executive Philip Bowman said, As part of our aim to become the UK’s best integrated power provider, we set ourselves a commitment to be number one for customer service and deliver excellent service to our 5.2 million customers. Driving down the number of complaints made to EnergyWatch, is an important milestone in realizing our aim.

However, as ScottishPower and many of its competitors have, to date, failed to pass on wholesale price reductions to customers, the UK utilities sector may be on the brink of a new wave of customer complaints.
