Methodology
This page uses September 2026 evidence and orders suppliers by the mean of qualifying iOS App Store and Google Play ratings; each store rating needs at least 50 ratings, and one qualifying store is enough. Missing criteria are not silently estimated. The annual tariff figure is supporting price context and is not part of the score. All price figures use a representative East Midlands postcode, Monthly Direct Debit and the stated Ofgem medium-use assumptions. Electricity-only, gas-only and dual-fuel rows may appear; readers should compare like with like and obtain a personalised quote before switching.

Our verdict
Scottish Power ranks first on this page’s September evidence.
Scottish Power scores 95/100 using the mean of qualifying iOS App Store and Google Play ratings; each store rating needs at least 50 ratings, and one qualifying store is enough.

Frequently asked questions
How is this page ranked?
Suppliers are ranked using the mean of qualifying iOS App Store and Google Play ratings; each store rating needs at least 50 ratings, and one qualifying store is enough. Missing evidence is shown or excluded according to the stated rule rather than being guessed.
Are these personalised prices?
No. Prices use an East Midlands representative postcode, Monthly Direct Debit and Ofgem medium-use assumptions. Your quote can differ with location, usage, meter and eligibility.
Does a variable or tracker tariff always have no exit fee?
No. Tariff type, contract term and exit fee are separate. Check the named tariff’s term and exit fee before switching.
Why can rankings move sharply between months?
The monthly table is rebuilt from the qualifying evidence available for that month. A tariff entering, leaving or changing price, or a rating or service measure changing, can move a supplier or tariff several places.
What does missing data mean?
It means the relevant comparable figure was not present under this page’s filters. Missing values are not estimated; check the supplier directly for current availability and a personalised quote.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
