A Which? report shared with the Guardian found the service offered by British Gas has worsened across all its satisfaction measures since its last analysis of the energy sector last year. While customer service has broadly improved across the industry, it has declined for customers of British Gas, according to the survey.

Rocio Concha, a policy director at Which?, said: "It is never OK for firms to provide substandard customer service, but in an essential sector like energy which millions rely on every day, it is unacceptable."
