A new analysis from the Energy and Utilities Alliance finds that 91 percent of heat pumps installed in existing UK homes in 2025/26 relied on government subsidies. The total cost to taxpayers and bill payers reached 498.6 million pounds, with the carbon savings costing 437 pounds per tonne of CO2e. That is above the government's own carbon valuation, making heat pump retrofits one of the most expensive abatement options available. The data covers 49,880 air source heat pump installations in existing homes. Schemes like the Boiler Upgrade Scheme, ECO, SHDF, and HUG provided the bulk of support. The report argues that the market is not consumer led when 91 percent of installations depend on public money. Critics say the policy is burning through cash without delivering a self sustaining market. The piece raises real questions about subsidy design and cost effectiveness in the UK's heat pump rollout.

Interesting numbers from the EUA. 91 percent of heat pump installs in existing homes needed a subsidy. That is a lot of public money for 50k units. The 437 per tonne carbon cost is above the government's own valuation. Worth reading the full breakdown.

The 437 per tonne number is the key figure. If the government values carbon lower than that, then the policy is not cost effective by its own metric. But the article does not say what the government's carbon price actually is. That matters for the comparison.

Also worth noting that the carbon savings depend on grid carbon intensity assumptions. If the grid gets cleaner faster than assumed, the lifetime savings per pump drop. That would push the cost per tonne even higher. The report uses Ofgem assumptions but those could be optimistic.

The bigger question is whether the subsidy structure is designed to eventually phase out. If 91 percent of installs still need support, the market is not transitioning. The Boiler Upgrade Scheme was meant to taper. It has not. That is a policy design failure, not a technology failure.

Agreed. The technology works. The issue is cost relative to gas boilers and the fact that installation is still expensive. Without a carbon price on heating fuel or a mandate, the subsidy dependency will persist. The 437 per tonne number is high but it depends on the counterfactual.
