Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what protections are available for heat network consumers in respect of back-billing; and whether he plans to introduce or require limits equivalent to the 12-month back-billing protections that apply to domestic gas and electricity customers in cases where the failure to bill is attributable to the supplier.

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), takes precedence. Under these rules, landlords have 18 months to notify or demand service charge payments, once costs have been incurred.

Ofgem have issued guidance, setting out their expectation that all heat network suppliers should adhere to the 12 month back-billing limit.

Heat networks consumers can get help and advice from Citizens Advice and Consumer Scotland. In addition, the Energy Ombudsman provides Alternative Dispute Resolution for heat network consumers.
