Shell Energy will pay a £390,000 penalty for overcharging domestic energy customers.
Regulator Ofgem said the company, then trading as First Utility, which the fossil major acquired last year and rebranded to Shell Energy this year, had overcharged about 8,800 customers.
Customers were either on accounts that did not comply with the domestic price cap, or experienced a delay in the tariff being reduced to be in line with the price cap.
The company will refund customers, pay compensation, and has agreed to pay £200,000 into Ofgem’s voluntary redress fund to help vulnerable customers. As such, the regulator will take no further action.
