Ofgem’s Heat Network Regulation is Now Live – What High-Rise Developers Must Do in 2026

The UK’s transition to net-zero carbon emissions has introduced significant regulatory changes within the energy sector, and the heat network industry is no exception. With the Energy Act 2023 naming Ofgem as the regulator for heat networks in Great Britain, the sector has now entered a new regulatory era.

As of January 2026, Ofgem has formally begun regulating heat networks in England, Scotland and Wales, launching new consumer protection rules and starting the move to a fully regulated framework for operators, suppliers and consumers. A transition period is now underway to help the sector implement the new requirements.

Ofgem’s regulatory role and the impact on high-rise residential developments

The Ofgem heat network regulation focusses on consumer protection, fair pricing, reliability, and technical performance standards. These standards include efficiency requirements, metering obligations, and authorisation for heat network providers to operate. High-rise residential buildings, which house a large number of homes in a compact space, pose unique challenges when it comes to heating and cooling systems. Centralised heating systems, like Community Heat Hubs (CHHs) and Networked Ground Source Heat Pumps (NGSHPs), offer efficient, low-carbon solutions that address these challenges while aligning with Ofgem’s standards.

For all heat networks to be operational, providers must be authorised by Ofgem. This means that heat networks in high-rise buildings need to adhere to standards that ensure consumer protections, technical performance, and energy efficiency.

Leading the way in heat network regulation

As Power On continues to expand its presence in the high-rise residential market, our approach already reflects the governance, assurance and technical standards now formalised under Ofgem’s regulatory framework. Our Networked Ground Source Heat Pumps (NGSHPs) and Community Heat Hubs (CHHs) are designed, delivered and operated to meet these expectations as standard.

Heat network systems should be built to:

• Ensure transparency and fair pricing: By offering clearly defined pricing models and a price promise, guaranteeing that the cost of heating solutions will be comparable or lower than traditional, less sustainable options.
• Incorporate smart metering: All systems should be equipped with advanced metering technologies to monitor energy use, ensuring accurate billing and providing real-time insights for consumers to optimise their energy consumption.
• Promote scalability and reliability: Modular design of Community Heat Hubs allows for scalability, making them suitable for a wide range of high-rise developments, from smaller buildings to large multi-unit residential blocks.

Any proactive compliance strategy must be grounded in a commitment to Ofgem’s consumer protection measures and ensure that solutions are in line with the Future Homes Standard and Part L of the Building Regulations.

Solutions for high-rise residential developments

In high-rise residential buildings, where individual heating solutions may not be feasible due to space constraints and high energy demand, Community Heat Hubs offer an ideal solution. These centralised systems efficiently distribute low-carbon heat to multiple units from a single, scalable source. The ability to integrate these systems with renewable energy sources such as solar power enhances the sustainability of the development, ensuring long-term resilience against future regulatory changes.

The NGSHP systems, meanwhile, utilise the earth’s natural thermal energy to provide efficient, low carbon heating for new and existing developments. These systems significantly reduce the carbon footprint of high-rise buildings, making them an attractive option for developers seeking to meet the requirements of the Future Homes Standard while adhering to Ofgem’s efficiency criteria.
Both solutions are fully compliant with Ofgem regulations, offering developers a pathway to meeting net-zero targets while reducing the regulatory burden on their projects.

Supporting developers and M&E consultants in the transition to electrification

Developers require a complete solution that not only addresses the regulatory requirements of Ofgem but also integrates seamlessly with the electrification of high-rise residential housing. With the regime now live, developers benefit from solutions designed with authorisation expectations, customer protections, metering and operational requirements in mind.

Developers also face challenges when connecting to the upstream electricity grid. By using Community Heat Hubs and NGSHPs, developers can reduce the impact of high energy loads, which is often a challenge for high-rise developments with numerous individual systems. This ensures that the heat network operates efficiently without overwhelming the local grid, supporting sustainability at
both the building and community levels.

Meeting the needs of the Future Homes Standard and Part L Regulations

The shift towards electrification and low-carbon heating solutions is driving changes in building standards, particularly in the residential sector. Future Homes Standard requires new homes to meet rigorous energy efficiency and carbon reduction targets. By adopting NGSHPs and CHHs, developers can support compliance with these standards, reducing carbon emissions and energy consumption.

Moreover, with Part L of the Building Regulations setting energy performance targets for new buildings, these heating solutions provide a pathway to compliance with high standards for energy efficiency and environmental performance.

Commitment to future-proof, compliant and sustainable heat networks

With Ofgem’s heat network regulation now in effect, Power On stands ready to support high-rise residential developments to operate compliantly within the new framework while remaining positioned for long-term sustainability. NGSHPs, Community Heat Hubs and integrated smart thermostat solutions provide a holistic approach to heating that supports efficiency, reliability and strong consumer protection.

Prioritising alignment with Ofgem, the Future Homes Standard and Part L helps developers and consultants navigate the evolving regulatory landscape while contributing to the UK’s net-zero goals. With innovative, low-carbon heating solutions, the industry can do more than meet regulatory requirements: it can deliver sustainable, future-proof heat networks for high-rise residential housing.
