Heat Networks (Market Framework) (Great Britain) (Amendment) Regulations 2025

Baroness Bloomfield of Hinton Waldrist Excerpts

Monday 15th December 2025 Grand Committee

[Baroness Bloomfield of Hinton Waldrist (Con)]

My Lords, I thank the Minister for setting out the purposes of these regulations. We welcome them, so I shall not overburden him with questions beyond those already asked by previous speakers. It is somewhat frustrating that I did not spot the error in the amendments to Regulation 56 in the current Regulation 10; I must do better. These measures represent another step towards the full regulatory framework for heat networks that consumers have waited too long to see. From January 2026, the full authorisation regime and the special administration powers are due to come into effect—a significant milestone that we welcome wholeheartedly.

As the Minister said, we must be clear about the situation facing many people with heat networks. Years of unregulated, decentralised heating have left households paying high and unpredictable costs, receiving confusing bills and unable to switch supplier or seek meaningful redress. Citizens Advice has warned that, for some, bills have doubled or even tripled, which is simply untenable.

Therefore, while we support these regulations, their success will depend entirely on effective implementation. A framework on paper is not enough; consumers need enforceable, practical protections. As the noble Baroness, Lady Bennett of Manor Castle, rightly identified, it is essential that Ofgem is fully prepared and properly resourced to take on its new responsibilities from 27 January. It must be able to intervene when prices are unfair, when service standards fall short and when vulnerable households are at risk of disconnection. Clear complaints processes must be in place, and operators must be held to account. Like the noble Earl, Lord Russell, I would be grateful if the Minister can provide assurances today that Ofgem will be ready from day one, with no gaps or uncertainty for existing heat networks customers.

The introduction of a special administrative regime is similarly welcome. But, again, the test will be in its delivery. Consumers must have confidence that, should a provider fail, essential heating will continue uninterrupted, particularly for households in the winter months. The demand and use of heat networks will continue to play an increasingly important role in our energy system, and it is vital that this regulatory framework is implemented swiftly and effectively. Consumers must be able to rely on heat that is affordable, transparent and properly overseen. Without that assurance, the sector will not expand at the scale required.

These regulations take us closer to a regime that commands consumer confidence; the task now is to ensure that the protections set out in the Energy Act are delivered in practice for the half a million households that depend on these networks.

[Lord Whitehead (Lab)]

I thank noble Lords for their valuable contributions to this debate. A number of them go to the heart of why we are doing what we are doing today: the question of the state of many of the older heat networks that exist in this country. They are very far from the sorts of standards that we would expect to bring forward in new heat networks, and they have often operated with very sub-optimal arrangements for many years, to the considerable detriment of customers.

Therefore, the regulatory regime that we are introducing should give an enormous amount of succour to those who have suffered under those heat networks over a long period. As mentioned by the noble Baroness, Lady Bennett, there are heat networks from the 1960s and the 1970s which simply have not updated what they do, and they will be held accountable for what they do in these networks by the new regime under Ofgem. Ofgem can introduce fines for the systems if they are found wanting and, as a measure of last resort, can ensure that those networks are transferred to the running of another organisation entirely.

The noble Baroness, Lady Bennett, also mentioned the report encompassing a number of these issues from Citizens Advice, and that is why its work as a consumer champion is so important. I can assure the noble Baroness that Ofgem will be ready for regulatory commitments. It has raised no questions about its capacity to introduce these regulations and to make sure that they work to maximum capacity from day one. Ofgem will, however, take action such as collecting pricing data and various other things to refine how the regulations may work over the early period of their operation.

I can assure the noble Baroness, Lady Bloomfield, and the noble Earl, Lord Russell, and all the noble Lords who raised concerns, that Ofgem will therefore be ready for regulatory commencement. Ofgem will be publishing what methodology will be used to determine reasonable pricing. This has recently been consulted on by Ofgem. However, the exact benchmark of what is considered fair pricing will not be published first, so that heat networks do not move their prices to the top of that benchmark.

Overall, therefore, I assure noble Lords that the scheme will work to the best of its design and ability from the word go and will properly encompass all the many and varied types of heat network we have in operation, with a view to bringing them all up to the same standard, rather than down to the same standard, for the future. Indeed, the instrument simply builds on previous regulations by introducing amendments that will expand the authorisation regime that Ofgem will implement. We have also heard mention of deemed contracts, which will be in place to ensure that the rights of households and their supply of heat are protected, even when there is no formal contract in place.

I am sure noble Lords will want to join me in thanking the District Energy Association heat authority, which tried to put a voluntary system into operation to secure compliance and uprating of systems. That has worked for 10 years. In itself, it has worked very well, but it encompasses only part of the heat network arena. This will cover everybody, so it will be a great step forward in that respect.

On the question of consultation, I understand that the four public consultations that have already taken place, dating back to February 2020, have informed the regulations, but the detailed Ofgem authorisation conditions and associated guidance are still being consulted on and will certainly be published before the authorisation regime commences on 27 January.

In conclusion, I consider that these regulations, which will include the most vulnerable, will now make sure that pretty much everybody enjoys statutory protections. Heat networks are indeed the future, and we must do everything we can to support their growth and instil confidence in that growth as it takes place. Sound and proportionate regulation is therefore central to delivering this and I beg to move.
