Heat networks: less than 3 months until "go live" date for regulation
With the "go live" date for regulation of heat networks fast approaching (27 January 2026), network operators - and some landlords - need to make sure they're prepared for the new regime.
Historically, businesses involved in the provision of heat networks have not been regulated in the same way as other utility providers – but that will change from 27 January 2026, when a new supervisory regime will be introduced under the Energy Act 2023, with Ofgem as regulator.
Unsurprisingly, heat network operators will be regulated – but landlords could also be caught (where they are involved in the supply of heat and hot water via networks). For example, if a lease includes the provision of heat and hot water via a heat network, the landlord may fall within scope – because it will be regarded as a "supplier". By contrast, where an energy services company (commonly referred to as an "ESCO") is appointed to run the heat network and contracts directly with customers, the landlord is unlikely to fall within scope. This arrangement – which avoids the landlord being regulated – is what we are typically seeing with new developments. However, where no ESCO is involved (or where the ESCO does not contract directly with customers), landlords – especially those of less recent developments - could be caught.
Regulated entities will be required to:
Whilst the final details of these conditions are still to be confirmed, draft materials published by Ofgem for consultation provide a reasonable steer on what is likely to be expected of regulated entities.
Although Ofgem will have power to enforce authorisation conditions from 27 January 2026, it appears to accept that full Day 1 compliance with all aspects of the regulatory regime is unrealistic. Key aspects of the regime will therefore be phased in over the course of 2026. For example, one of the requirements is to register with Ofgem – but regulated entities will not be able to do so until the launch of the digital service for heat network regulation in Spring 2026. Indeed, the deadline for registration is not until 26 January 2027, which gives regulated entities more time to comply with requirements such as drawing up continuity plans (which they are expected to have in place before registering). Similarly, Ofgem does not expect to introduce data reporting requirements until "the latter part of 2026" – although it will expect data to be collected by regulated entities from April 2026 (which is only 5 months away).
That said, if Ofgem were to become aware that a regulated entity was behaving in a way which gave it significant cause for concern (e.g. because it was leading to serious customer detriment), our view is that it could very well decide to act on the basis of its new regulatory powers – notwithstanding that the "full fat" regulatory regime was still effectively being rolled out. Regulated entities will also need to ensure that they have adequate systems and resources in place to meet the ongoing demands of the new regime e.g. as regards regular reporting requirements and consumer protection standards.
