Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what action they are taking against energy suppliers who issue exaggerated gas and electricity back-bills where the calculation is based on (1) incorrect readings, or (2) readings not submitted or approved by the tenant being charged.

Ofgem are responsible for enforcing supplier licence conditions. Tenants should take a meter reading as soon as they move into a property. Customers will not be responsible for energy bills with incorrect meter readings and can request a new bill from their supplier if they have been billed incorrectly.

Residential tenants are responsible for paying energy bills from the start date of their tenancy only. For non-domestic tenants, Ofgem's recent non-domestic market review found some issues with changing of tenancies, including debt repayment issues from previous tenants. The Retail Energy Code Company is working on new rules in this area.
