ScottishPower has revealed that it's been able to retain its customer levels during the first half of this year.
Owned by Spanish company Iberdrola, the energy supplier revealed that its customer base remained at 5.6 million - the same amount it registered in June and December of last year (2013). In total, 2.2 million of these customers are on its gas tariffs, whilst 3.4 million are electricity customers.
The news came as the big six energy supplier announced that its half-year earnings were higher in spite of a fall in demand. In the UK its earnings increased 8.5 per cent to £192 million. However, it also revealed that the margins in earnings for ScottishPower's retail supply business were lower. This shortfall was made up for through the company's generation arm.
Last winter, ScottishPower implemented price rises of 8.5 per cent and 9 per cent to its gas and electricity tariffs. It later reduced its energy prices as a result of changes to green levies.
Iberdrola, meanwhile, announced that its first-half net profits fell by 13 per cent to £1.19 billion.
In a statement, ScottishPower's Spanish owner said: "A good business performance, mainly in international operations, has allowed us to partially compensate for the impact of regulatory measures in Spain."
