Caldora Compliance
Checker

Do I need to register my heat network?

Four questions. It tells you whether the network must be registered with Ofgem by 26 January 2027, and which of the 29 authorisation conditions would apply to you.

Nothing is submitted and no address is asked for. It applies the same applicability rules the Caldora platform applies internally, so the answer is the one the product would give.

1. Does the network serve two or more end users?

An end user is a separate dwelling or business unit taking heat, cooling or hot water. A single house with its own boiler is not a heat network.

2. What is your part in it?

The operator runs the physical network. The supplier holds the relationship with consumers and charges them for heat. One party often does both.

The short version

A heat network is any arrangement supplying heat, cooling or hot water from a central source to two or more end users. That is a wider net than most people expect: it catches communal systems inside one building, not just district schemes across a site.

Registration is per network. A landlord with twelve buildings has twelve registrations. Whether you register as operator, supplier or both decides which conditions you then carry — and appointing a managing agent or contractor to do the work does not move the accountability. Appointing an ESCO under a long-term contract is different: the ESCO takes on the operator or supplier role itself, so the accountability moves with it. The condition guidance recognises that distinction.

The deadline is 26 January 2027, and the full text of every condition is published here.
