If your heating and hot water come from a shared communal or district system rather than your own boiler, you’re on a heat network — a genuinely different arrangement from anything else covered on this site, and one that’s just become formally regulated.

What a heat network actually is

A heat network supplies heat (and often hot water) to multiple properties from a shared central source — a communal boiler or energy centre serving a single block of flats, or a larger district system serving an entire development or neighbourhood — rather than each home having its own individual boiler. If you live somewhere with a heat network, you don’t choose or maintain a boiler at all in the way the rest of this site assumes; instead, you’re a customer of the heat network operator, paying for heat supplied, typically through a meter.

Why heat networks haven’t historically been regulated like gas and electricity

Until recently, heat network customers didn’t have the same statutory protections as gas and electricity customers — there was no equivalent of Ofgem oversight, no price cap, and comparatively limited formal recourse if billing, service quality or supply reliability fell short. The foundational obligations that did exist came from the Heat Network (Metering and Billing) Regulations 2014, which set some baseline requirements around metering and billing, but stopped well short of the fuller consumer protection framework that applies to gas and electricity.

Ofgem becomes the statutory heat networks regulator

The Energy Act 2023 changed this by appointing Ofgem as the dedicated heat networks regulator across England, Scotland and Wales, governing organisations that supply or operate a heat network. Ofgem’s own guidance confirms that from 27 January 2026, it became the statutory heat networks regulator, with a package of consumer protection rules taking effect from that date, including a set of general authorisation conditions that heat network operators and suppliers must now comply with.

What the new protections actually cover

Ofgem’s guidance sets out that the framework is intended to give heat network customers protection broadly comparable to gas and electricity customers, covering standards of conduct, quality of service, billing and transparency (including back-billing limits), the content of heat supply contracts, specific protections for customers in vulnerable situations, and security of supply. Ofgem has also confirmed that the fuller set of regulations is being phased in, with the majority planned to be in place and enforced by January 2027 — meaning the full protection framework is still being rolled out even after the initial January 2026 start date.

What this means if you’re buying or renting a home on a heat network

If you’re considering a property connected to a heat network, rather than one with its own boiler, it’s worth asking specifically who the heat network operator is, and confirming they’re operating under Ofgem’s new authorisation framework rather than assuming heat network status automatically means the same protections as a standard gas or electricity supply. This is a genuinely different commercial and regulatory relationship from owning your own boiler, which is the default assumption behind most of the rest of this site’s boiler-buying guidance.

FAQs

Do I have a choice of heat network supplier the way I can switch gas or electricity supplier?

Generally no — a heat network is typically tied to the building’s physical infrastructure, so unlike gas or electricity, you usually can’t switch to a different heat network provider while remaining in the same property.

Does a heat network mean I can’t have a Boiler Upgrade Scheme grant or a heat pump of my own?

If your property is served by a communal or district heat network, an individual heat pump for your home specifically usually isn’t relevant, since the heating decision is made at the building or network level rather than per household.

Were there any consumer protections for heat network customers before January 2026?

Some baseline requirements existed under the Heat Network (Metering and Billing) Regulations 2014, covering metering and billing specifically, but the fuller consumer protection framework comparable to gas and electricity customers is what began from January 2026 under Ofgem’s new regulatory role.
