Energy: Billing

Asked by Bell Ribeiro-AddyLabourDepartment for Energy Security and Net ZeroTabled Answered 25 February 2026UIN 114011

The question

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential implications for his polices of heat network operators issuing retrospective bills covering multiple years where no prior invoices or statements were provided.

Answered by Martin McCluskey

Under the newly established heat network market framework, Ofgem Authorisation conditions limit back-billing to 12 months if no accurate bill or statement of account was previously provided.

Where heat charges are ‘bundled’ into leasehold or social housing charges, the Landlord and Tenant Act (1985), which caps back-billing at 18 months, takes precedence.

We are working closely with the Ministry of Housing, Communities to explore unbundling individual consumption of heat from service charges so that the 12-month back billing rules apply to all heat network consumers.
