ScottishPower Named Worst UK Energy Supplier by Which?
ScottishPower Named Worst UK Energy Supplier by Which?

ScottishPower has been ranked the worst energy supplier for customer service in Great Britain, according to a survey by consumer group Which?. The survey, based on responses from nearly 12,000 customers, placed British Gas and EDF Energy just above ScottishPower at the bottom of the annual rankings.

Which? found that ScottishPower had the lowest customer satisfaction score and tied with EDF Energy for the second-lowest overall assessment. So Energy finished fourth from bottom, while Ovo Energy ranked fifth from bottom. E.ON Next, Ecotricity, and Fuse Energy tied as the sixth worst suppliers.

Emily Seymour, Which? energy editor, said: 'While four suppliers are outshining the competition, some big firms – including ScottishPower, EDF and British Gas – are letting their customers down.' The three lowest-scoring suppliers disputed the rankings, noting that they sometimes contradicted customer service scores from Citizens Advice and Ofgem.

A ScottishPower spokesperson said the Citizens Advice scorecard showed 'sustained, high-quality delivery' and used 'much more robust and transparent methodology' than the Which? survey. British Gas pointed to Ofgem data showing it achieved the second-highest overall satisfaction score among major suppliers, with complaints falling by over 20% in each of the past two years. EDF Energy acknowledged areas for improvement but highlighted strengths in supporting customers needing extra help.

Which? awarded 'recommended provider' status to four suppliers: E (Gas and Electricity), Octopus Energy, 100Green, and Sainsbury's Energy. Octopus Energy, the UK's largest domestic supplier, finished second overall and was recommended for the ninth consecutive year. Greg Jackson, Octopus Energy's founder and CEO, said: 'This isn't about scale – it's about consistently focusing on our customers to deliver value, service and innovation.'
