London’s Mayor Sparks Heat‑Network SOS
Mayor Sadiq Khan has issued an urgent plea: the 400,000 Londoners who live on communal heat networks must get the same protection as homeowners with personal boilers, or they’ll be left with sky‑high bills.
What’s a Communal Heat Network?
- Heat that flows from a single boiler or plant to several homes.
- Think of a large block of flats or a whole neighbourhood heating system.
- No need for a snazzy gas line in every apartment.
Why They’re Left Hanging
Communal systems often rely on gas – about 90% do. But the gas they buy comes from a commercial market that’s unregulated by price caps, whereas individual customers benefit from the government’s 7.52p/kWh cap. Prices in this unregulated market have surged façades of mint green legs in recent months.
Khan’s Proposal
He’s got a game plan: if a heat‑network provider can prove that the effective price on a per‑kWh basis is higher than the domestic cap, the government should cash in support to bring these costs in line.
- Revenue comes from a £100 million rebate scheme spread out over 200,000 households.
- Each homeowner could receive about £500 – roughly the difference between 2021 and 2022 domestic gas bills.
- The goal: to equalise communal heat bills with those of regular domestic customers.
Why It’s Urgent
The city’s new default tariff cap starts October, and we’re already bracing for a winter where bills climb faster than a hot‑roll. Khan wants this put in place now, especially before winter hits.
Data is telling:
- Over half of London’s 200,000 communal homes are social housing.
- 32% are in private rentals.
- That’s a sobering fact: the most vulnerable Londoners are the ones facing the largest unregulated price hikes.
Broader Implications
Communal and district heating can slash building emissions and help London hit its net‑zero goal by 2030. But the current market volatility threatens to chip away at the city’s climate ambitions.
Mayor’s Words
“All Londoners feel the price‑of‑living squeeze. It’s the folks on the margins who are the hardest hit,” says Khan. “We’ve got more people on communal heating here than anywhere else in the country. Fairness demands we treat all Londoners equally. Heat networks are a crucial climate tool; we must shield their customers from wild market swings.”
Government Response
A spokesperson took a hopeful tone, noting the £37 billion support package that already helps people on heat networks. They also highlighted upcoming legislation that will appoint Ofgem as the regulator for heat networks – a move that should ensure fair pricing.
Industry’s Support
Simon Woodward (UKDEA) and Caroline Bragg (ADE) echoed the Mayor’s call, insisting that government funding must rise to protect heat‑network customers before winter’s steep bill hike.
Stephen Knight (Heat Trust) added sharp commentary: “There’s a huge injustice. Price spikes of 300‑400% – even 700% – are happening in the communal sector. The government must step in.”
In short, this is a bold push to level the playing field for London’s heat‑network dwellers – and to keep the city’s climate noble goals intact while easing the financial stress on its most vulnerable residents.
