Heat Network (Metering and Billing) Regulations 2014
Source: si-2014-3120-heat-network-metering.md Last updated: 2026-04-05
What this instrument does
The Heat Network (Metering and Billing) Regulations 2014 (SI 2014/3120) impose metering and billing obligations on heat suppliers operating district heat networks and communal heating systems. Originally implementing EU Energy Efficiency Directive Articles 9-11, the instrument has been substantially reduced since January 2026 as the Energy Act 2023 Part 7 Heat Networks Market Framework takes over.
Building classification (Reg.2A)
Since November 2020 (SI 2020/1221), buildings are classified into three tiers that determine which metering duties apply:
- Viable class: new builds or major renovations. Full metering duties apply.
- Open class: multiple entry points or vulnerable occupants. Subject to cost-effectiveness analysis.
- Exempt class: non-water distribution systems or leasehold restrictions. Metering duties disapplied.
Metering obligations (Regs.4-5, 7-8), still operative
Heat suppliers must install meters on district heat networks (Reg.4(1)-(4)), positioned at the heat exchanger or building entry point (Reg.4(2)). Meters must accurately measure, memorise and display consumption (Reg.5). Replacement meters must meet the same standard (Reg.7(1)), with an exemption where technically impossible or unreasonably expensive (Reg.7(3)). Suppliers must keep meters continuously operating and properly maintained (Reg.8).
Where cost-effectiveness analysis is negative, the supplier must re-assess every four years (Reg.4(7)).
Omitted provisions (since 27 January 2026)
SI 2026/7 removed for England, Wales and Scotland: - Notification duty (Reg.3): heat suppliers no longer required to notify SoS of network operation - Heat cost allocators (Reg.6): no duty to install HCAs, TRVs, or hot water meters - Billing requirements (Reg.9): no requirement for consumption-based billing or Schedule 2 billing information - Cost-effectiveness analysis (Schedule 1) and billing information standards (Schedule 2): omitted
Reg.8A (inserted January 2026) confirms that suppliers previously under Reg.6 obligations are released.
Enforcement (Regs.10-14)
Enforced by the Secretary of State (or Scottish Ministers for Scottish networks) (Reg.10(1)). Offences include failure to comply with ongoing maintenance obligations (Reg.11(1)(e)) and obstruction of authorised persons (Reg.11(3)). Penalties: up to level 5 on the standard scale for maintenance and obstruction offences (Reg.13(1)); unlimited fine on indictment for other offences (Reg.13(2)). Civil sanctions available under Schedule 4.
12-month prosecution time limit from date evidence comes to knowledge (Reg.14).
Transition to Heat Networks Market Framework
The Energy Act 2023 Part 7 creates a licensing regime for heat networks administered by Ofgem, replacing these regulations. The three-tier building classification introduced in 2020 may inform the new regime's approach to metering obligations.
