The Rising Cost of Comfort: Are Heat Networks a Hotbed of Consumer Issues?
For Anja Georgiou and her family in Greenwich, London, the promise of modern, efficient heating has turned into a financial burden. Residents of the River Gardens development were unexpectedly presented with a substantial bill for their communal heating system, highlighting a growing concern for the half a million to one million UK households connected to heat networks.
What are Heat Networks and Why are They Becoming More Common?
Also known as district heating systems, heat networks deliver heat from a central source through a network of insulated pipes. Typically, landlords or freeholders purchase energy on the commercial market for residents. These systems are increasingly popular, with almost three-quarters of new homes in London now incorporating them. The government hopes heat networks will supply a fifth of England’s heat by 2050, a significant increase from the current 3%.
The River Gardens Dispute: A Case Study in Unfair Billing
Residents of River Gardens faced a £198,986 debt accumulated between 2022 and 2023, which was then passed onto homeowners and tenants based on their usage. Calum Matheson, a leaseholder, was billed an extra £550. The managing agent, Rendall & Rittner (R&R), attributed the debt to a delay in adjusting tariffs after their energy supplier, With Energy, ceased providing gas for the building. A property tribunal ultimately ruled in favor of the residents, deeming the debt “irrecoverable as service charges.”
This case illustrates a critical issue: the potential for retrospective billing and unfair charges within unregulated heat networks. The terms of the original energy contracts stated With Energy would bear the risk of gas market volatility, further supporting the residents’ claim.
New Regulations: A Step in the Right Direction?
Until recently, the heat network sector operated without formal regulation. Although, as of January 27, 2026, Ofgem, the UK’s energy regulator, has begun overseeing the sector to protect customers from unfair price hikes. New protections took effect in 2025, including access to the Energy Ombudsman for dispute resolution and a new advice service provided by Consumer Scotland and Citizens Advice.
The Problem with Price Volatility and Lack of a Price Cap
Unlike traditional gas and electricity customers, those on heat networks are not protected by Ofgem’s price cap. This vulnerability was exposed during the energy crisis following the Russian invasion of Ukraine, with some customers experiencing energy cost surges of up to 450%. Whereas Ofgem will monitor prices and can intervene, there isn’t currently an equivalent of the price cap for heat network customers.
What Does the Future Hold for Heat Networks?
While regulation is a positive step, challenges remain. Stephen Knight, chief executive of Heat Trust, emphasizes the need for proper price protection. The current rule requiring “fair and proportionate” pricing lacks the concrete safeguards offered by a price cap.
The Role of Technology and Innovation
The success of heat networks hinges on efficient operation and transparent billing. Innovations in smart metering and data analytics can play a crucial role in providing customers with accurate usage information and preventing disputes. Projects like the district heat and power project in Gateshead, utilizing waste heat, demonstrate the potential for sustainable and cost-effective heating solutions.
Pro Tip:
If you are connected to a heat network, carefully review your energy contract and understand the terms and conditions regarding pricing, billing, and dispute resolution. Keep detailed records of your energy usage and payments.
