Moved house
Moved house, was able to speak to a real person in the first instance who was fantastic and took over all the necessary work to transfer over to new property at the best rate on the day we moved. Great service.

Top Class Energy Provider
I have had no problems working with SP and I like the services provided. I have just changed from their standard tariff to a one year fixed tariff, saving me a tidy sum of money each month. We get half price electricity for 5 hrs on a Sat & Sun, and we make full use of this cost saving feature. Truly excellent service.

Savings based on a comparison between the annual bill for a typical household on SVT and a typical household on our fixed price tariff. All values are based on a typical household that uses 11,500kWh of gas a year, and 2,700kWh of electricity a year, paying by Direct Debit. T&Cs apply. Subject to availability.

Electricity used will be charged at your normal unit rate and you will later have your bill credited for the energy you used. The credit is calculated as half of your electricity unit rate (excluding VAT) and will show as 'Power Saver Credit’ on your bill or statement. Your daily standing charge will be paid at your normal rate. See Terms and Conditions.

Scores from January to March 2025. Accurate as of 25 June 2025. Excludes Northern Ireland. Ofgem defines large energy suppliers as those with a market share of at least 5% in either gas or electricity. See http://www.citizensadvice.org.uk.

All electricity used will be charged at your normal unit rate based on your ScottishPower tariff. The credit for your EV smart charging session will appear as credit on your bill. The greenest times of day will be when the carbon intensity of the electricity required to charge your EV is at its lowest. This will vary each day depending on a number of factors, including weather conditions, renewable energy generation and demand on the grid.
