As of 2019, it serviced 2.86 million electricity customers, of which nearly 94 percent were domestic accounts. However, figures have been steadily declining since 2014. Additionally, ScottishPower also provides gas for 1.9 million customers. Its distribution network includes Central and Southern Scotland, North Wales and a few counties in England.
In October 2018, ScottishPower completed sales of its last remaining gas plant, thus becoming one hundred percent reliant of renewable energy sources. The following year, the group generated 5.12 billion British pounds in revenues, marking the second year in a row that figures had increased. That same year, net profits reached 552.9 million British pounds.
Scottish Power received over 341,000 complaints in 2019. Figures peaked in the first quarter of 2018 and have decreased since. Despite this decline, in 2019, ScottishPower had only resolved between 74 and 82 percent of complaints within eight weeks. This was a notably lower rate than its Big Six competitors.
When it comes to its Big Six competitors, ScottishPower ranked second in earnings from energy generation, which amounted to 273 million British pounds in 2018. Similarly, it also ranked second in profits from domestic energy supply.
