Heat Network Compliance (https://heatnetworkcompliance.co.uk) provides specialist regulatory guidance and digital compliance tools for UK heat network operators and suppliers preparing for Ofgem authorisation under the Heat Networks (Market Framework) Regulations 2025. With Ofgem regulation commencing on 27 January 2026 and registration opening in spring 2026, operators face a complex transition from deemed authorisation to full regulatory compliance — our platform is designed to make that transition manageable.

Our Policy and Compliance Document Generator (https://policy.heatnetworkcompliance.co.uk) helps operators create the documentation required to meet their authorisation conditions — including complaints procedures, vulnerability policies, supply contracts, pricing policies, and consumer protection statements aligned with the Standards of Conduct.
Our HIU Commissioning Tool (https://hiu.heatnetworkcompliance.co.uk ) is a mobile-first digital platform for commissioning and acceptance testing of Heat Interface Units. Engineers can complete standardised CIBSE CP1 test procedures on site, record flow rates, temperatures, and differential pressure measurements, calculate VWART performance, capture photographs and digital signatures, and generate professional PDF commissioning certificates. The tool works offline for plant rooms and risers with poor connectivity, syncing automatically when back online. Properly commissioned HIUs are fundamental to achieving low return temperatures and meeting HNTAS technical standards.
Our FREE Tariff Calculator (https://tariff.heatnetworkcompliance.co.uk ) enables operators to model fuel costs across gas, electricity, biomass, and heat pump systems, calculate plant efficiency and distribution losses, and produce compliant unit rates (p/kWh) and standing charges. The calculator includes counterfactual comparison against individual gas boiler costs, scenario modelling for different fuel prices and operating conditions, and board-ready PDF reports with full methodology documentation — all aligned with Ofgem’s fair pricing principles and Authorisation Condition A7 and A8 requirements.
We work with heat network operators and suppliers of all sizes, from small communal boiler schemes to large district heating networks, as well as housing associations, local authorities, ESCOs, managing agents, billing agents, and energy consultants. Whether you are preparing for registration, building your compliance evidence base, or looking to improve network performance through better HIU commissioning and transparent tariff-setting, Heat Network Compliance provides the practical tools and guidance to get it done.
