Headquartered in Glasgow, ScottishPower was formed in 1990 and became one of the former "big six" when the UK's energy industry was opened up to competition. Since then it has maintained its position as one of the UK's biggest energy suppliers, partly as a result of taking on the customers of failed suppliers as the energy market crisis developed.
As one of the biggest energy suppliers in the UK, there are a wide range of ScottishPower tariffs on offer to help meet the needs of as many customers as possible.
Like most energy providers operating in the UK, ScottishPower is subject to Ofgem's energy price cap. The cap sets the maximum rate that can be charged for ScottishPower's Standard tariff. The cap was set at its highest ever level of £1,971 in February 2022, coming into effect in April. ScottishPower therefore set its SVT rate at £1,970.53.
In August 2021, Ofgem announced that it would be increasing the level of the price cap by 12% to £1,277. As a result, ScottishPower announced an increase in its standard variable tariff to that new cap level. The prices will come into effect on 1 October 2021.
In February 2021, ScottishPower prices were increased by 9% on the supplier's standard variable tariff in line with the new price cap rate announced by Ofgem. The price rise came into effect on 1 April 2021 and affected customers on ScottishPower's Standard tariff. Prices on this plan increased to £1,138 per year for average usage - a price rise of around £96 per year.
The table below shows recent changes to ScottishPower prices, alongside changes by the rest of the big six energy suppliers:
In August 2020, ScottishPower announced it would reduce the average price of its standard variable tariff by 7% as of 1 October 2020. This price cut was in line with the revised energy price cap, and reduced the average cost of a standard variable tariff for ScottishPower customers by £84 a year.
In March 2020, ScottishPower prices were cut by 1% on the supplier's standard variable tariff, in effect from 1 April. Once again, the reduction was in line with the reduced announced in February 2020.
In August 2019, ScottishPower prices dropped by an average of £76 per year (6%) on its standard variable tariff, also in reaction to a drop in the price cap rate.
In February 2019, ScottishPower became the fifth of the big six energy suppliers to announce a price rise in reaction to the change in price cap at the time.
From 1 April 2019, rates for ScottishPower's standard variable tariff increased by £117 (10%), in line with the increased energy price cap of £1,254 per year.
In April 2018, ScottishPower prices were increased by 5.5% to customers on its standard variable rate plan, effective 1 June 2018. The change saw costs increase by £63 per year on average.
