A shocking £200,000 heating bill has sparked a battle for justice among London flat dwellers. This story is a real eye-opener, and it's one that deserves to be told. Imagine receiving a bill that could change your entire financial situation, all because of a complex energy network system.
Anja Georgiou, a mother living in a rented flat in Greenwich, London, shares her frustration. She describes her neighborhood as "very nice," with beautiful views and amenities, but the recent turn of events has left her feeling trapped.
"If I could move, I would," she says, "but this debt is a heavy burden."
Three years ago, residents of River Gardens, a development in Greenwich, were hit with a surprise bill for heating and hot water, totaling a staggering £200,000. This bill has caused a ripple effect, impacting the lives of many residents.
Here's where it gets controversial: the development uses a communal boiler, a common feature in many new builds. This system, known as a heat network or district heating, supplies heat from a central source through a network of pipes carrying hot water. The supplier is typically the landlord or freeholder, who purchases energy on the commercial market for residents.
Despite its growing popularity, with almost three-quarters of new homes in London now using heat networks, the industry was unregulated until recently. On January 27th, Ofgem, the energy regulator, stepped in to oversee the sector, aiming to protect customers from unfair price hikes. This move is a welcome relief for the 500,000 to 1 million households connected to heat networks.
In the spring of 2023, River Gardens residents were informed of an upcoming change to their energy tariff. The new rates were set to increase significantly, from 20p to 37p or 39p per kilowatt-hour, along with a standing charge. But that wasn't the only issue.
The development's managing agent, Rendall & Rittner (R&R), revealed an additional charge due to a debt of £198,986 accumulated on the heat network's energy account over a 15-month period. Calum Matheson, a software developer and leaseholder in the same block, was told he owed an extra £550. He immediately took action, determined to fight this unfair charge.
"It was plainly wrong," Matheson says. "I had paid my bills. They can't just send me an extra one out of the blue."
Residents who had kept up with their payments were confused and frustrated. In a follow-up letter, R&R, which manages a staggering 90,000 homes, attempted to explain the situation.
According to R&R, the energy supplier, With Energy, stopped purchasing gas for the building in 2022, and R&R's procurement arm took over. However, during this transition, the price of gas nearly doubled, and R&R failed to get With Energy, who still issues the bills, to review the tariff paid by residents promptly.
This "regrettable delay," as R&R put it, resulted in a deficit between the cost of gas used to operate the heat network and the bills being paid. The debt was then distributed among homeowners and tenants based on their usage during the period, with bills ranging from £50 to £600. Anja Georgiou's share was £337.
R&R warned residents that they couldn't switch to the cheaper deal secured for winter 2023 until the debt was cleared. This letter sparked outrage among the residents.
"Our energy contracts had clear terms and conditions," Georgiou says. "I cannot believe they think they can just send a letter, saying they should have charged higher tariffs on already paid invoices, and show over £300 outstanding on my account with no bill. It's outrageous!"
Matheson was determined to fight this battle. He reached out to various organizations for help, including the Energy Ombudsman, but was initially turned away. However, since April 2023, new legislation has allowed heat network customers to use the ombudsman service. When it became clear that the landlord would seek to recover the debt from individual leaseholders through the service charge, Matheson took the matter to a first-tier property tribunal, a specialized body for common property disputes.
"There is no legal basis for charging historical tariff increases to residents," Matheson argues, pointing to the terms and conditions on their energy bills. "With Energy agreed to bear the risk of volatility in the gas markets. Consumer protection law also prevents additional charges for energy already used and paid for at published and contracted prices."
Matheson represented himself and 56 other leaseholders at the tribunal, a process he describes as requiring "hundreds of hours' work." Last month, their hard work paid off when the tribunal ruled in their favor. The tribunal stated that the money is "irrecoverable as service charges under the respective leases."
Additionally, 20% of R&R's fees for the 15-month period when the debt arose were disallowed. Many residents, including Matheson, had paid their share of the bill in 2024 after receiving threatening letters stating that failure to pay would result in legal action.
While the tribunal cannot order a refund, the debt remains outstanding on Georgiou's account at the time of writing.
An R&R spokesperson commented, "We are aware of the tribunal's findings. We are reviewing the matter and will liaise with our client regarding the heating charges, which are legally payable to our client rather than Rendall & Rittner. We have not raised any fees related to the heat services at River Gardens."
Matheson hopes that R&R will restore residents to their rightful financial positions. He also expressed his satisfaction that this issue is now out in the open, knowing that similar situations are happening across the country. He hopes it will make developers think twice before taking such actions.
"As a point of principle, I'd also like my £550 back," Matheson adds.
Stephen Knight, the chief executive of Heat Trust, a consumer champion for people on heat networks in Great Britain, says, "We see this quite often. What they were trying to do was increase the price of a service retrospectively. One of the new rules is that tariff rates must be announced 31 days before they take effect. This will effectively outlaw this practice."
The introduction of Ofgem's oversight of heat networks is a significant step forward. They can now intervene if customers face unfair price hikes or poor service. With heat networks playing a crucial role in the country's net-zero goals, it's essential to ensure fair treatment for customers.
The vulnerability of heat network customers came to light during the energy crisis caused by the Russian invasion of Ukraine. Before the war, operators could purchase gas at a fraction of the price paid by domestic consumers, but with turbulent gas prices, some heat network customers saw their energy costs skyrocket by up to 450%.
Despite these challenges, heat networks are a key component of the country's net-zero strategy. The government aims for heat networks to supply a fifth of England's heat by 2050, up from just 3% today.
The Competition and Markets Authority has long advocated for the proper regulation of heat networks, and their increasing rollout has made this even more crucial.
Helena Charlton, Ofgem's director of heat networks, emphasizes the need for clear protections.
"Many heat network customers already receive a good service," she says, "but too many face unclear bills, poor communication, or uncertainty when things go wrong."
The new regime aims to ensure that customers understand their bills, that prices are fair, and that their heat supply is reliable. "These protections are commonplace for gas and electricity customers, and heat network customers can expect the same in the future," Charlton adds.
Some new protections came into effect in 2025, with the Energy Ombudsman now accepting disputes related to heat networks, and a new advice service launched by Consumer Scotland and Citizens Advice in England and Wales.
Stephen Knight believes that regulation is "long overdue." With an increasing number of people on heat networks, clear rules are essential. "There's a whole range of detriment issues due to the lack of proper regulation in this sector," he says.
"The new Ofgem rules include a package of protections, which is a significant step forward, but we still lack proper price protection, similar to the price cap. All we have is a general rule that pricing must be fair and proportionate, and Ofgem will monitor prices and intervene if needed."
This story highlights the importance of consumer protection and the need for clear regulations in the energy sector. It's a complex issue, but one that deserves attention to ensure fair treatment for all.
