ScottishPower offers a wide range of gas and electricity tariffs to customers across the UK, not just those north of the border. It also markets itself as a green technology expert and pioneer in renewable energy generation, having opened its first windfarm in Cornwall back in 1992.

ScottishPower was founded back in 1990 and quickly established itself as one of the UK’s original big six energy suppliers. In 2007, it was acquired by Spanish utility provider Iberdrola. The company says it’s the first UK supplier to generate 100% of the renewable electricity its customers use from its own renewable generators, primarily windfarms.

The company has just over 3.8 million customers as of December 2023. This gives it 8.6% of the electricity supply market and 7.4% of the gas supply market, according to Ofgem.

Over 71,000 customers have rated ScottishPower on TrustPilot as of April 2024. They awarded it an average 4.2-star rating, with 55% of respondents giving it the maximum 5 stars.

ScottishPower tariffs include a range of fixed-rate and variable plans. They’re suitable for customers looking for a dual fuel, electric-only or gas-only energy plan.

Currently, the company offers both 1-year and 2-year fixed tariffs called Flexi tariffs. 2-year Flexi tariffs come with the promise of 100% renewable electricity from ScottishPower’s own windfarms. There is a £75 exit fee for each fuel (electricity and/or gas) should you switch tariffs before entering the final 49 days of the tariff.

ScottishPower’s standard variable tariff follows the prices set by Ofgem’s energy price cap, which is updated every three months. There are no exit fees or tariff end date.

The company also offers an EV Saver tariff for ScottishPower customers with a smart meter and home EV charger. This tariff charges a discount rate for electricity used between midnight and 5am, and also comes with 100% renewable electricity. A complete home EV charger package (including installation) is available for those who have an electric vehicle, but no home charger installed.

ScottishPower offers a range of home services, including service and cover plans for appliances, heating systems, boilers and plumbing. The company also offers installation services for home EV chargers, solar panels and batteries, air source heat pumps and more.

ScottishPower supports the full range of meters: standard credit and prepayment meters, as well as newer smart meters. It supports both single-rate and multi-rate (Economy 7 or Economy 10) meters. Some tariffs – including its EV Saver tariff – will only work with smart meters.

Yes, ScottishPower offers 100% renewable electricity with select plans. Its 38 onshore windfarm sites provide enough energy to power over 1.2 million homes. However, renewable electricity contributes only 29% to its overall fuel mix. This compares to 41% across the UK.
