Consumer protection obligations under the Heat Networks (Market Framework) Regulations 2025 have been live since January 2026. Your first quarterly data submission covers April to June 2026 and is due 15 July 2026. Mixed-use buildings face the most technically complex compliance picture. Two different benchmark frameworks apply within the same building — domestic (≤14.0p/kWh) and non-domestic (≤18.0p/kWh). Distribution loss allocation between residential and commercial uses must be documented. Full residential consumer protections apply where any domestic consumers are present.
Spinview is an asset intelligence platform that holds your compliance data in one structured evidence base and does the calculation for you. One platform covers four obligations: Ofgem A9 reporting, HNTAS readiness with automated gap analysis, fair pricing evidence, and Scope 1 and 2 carbon reporting. The platform does the calculation. The assessor makes the determination.
The Heat Network Technical Assurance Scheme (HNTAS) introduces a structured technical standard for all operators. Expected to launch in 2027. Assesses networks across six areas: Energy Centre (EC), Connected Distribution Network (CDN), Building Connection (BC), Consumer Connection (CC), Metering and Monitoring (MM), and District Distribution Network (DDN). All KPI thresholds remain in draft pending final Ofgem publication.
The registration deadline is 26 January 2027. Every in-scope operator must register each network with Ofgem through the Heat Networks Digital Service by that date. Operating without registration after this date is a criminal offence.
