SHAREHOLDERS at British Gas will demand today that the company pays back its part of £2.5 billion energy companies made from overcharging their costumers in 2015.

Britain’s largest energy provider Centrica, which owns British Gas, will be meeting in London for its yearly AGM and ethical investors in the firm will be quizzing managers over allegations that customers were “extorted and bullied.”

The company’s introduction of pre-payment meters has been described by households as “predatory,” with customers having installations forced upon them by British Gas engineers.
