The King’s Speech on 17 July 2024 included three new bills targeting water and energy, the first time a Labour government has set out its environmental stall in over a decade. But the reaction from green groups was a study in qualified relief: welcome on water and energy, sharp criticism on aviation and the absence of a clean power bill. For UK homeowners, the real question is not what Parliament debated, but what lands on your bill and your EPC rating.
As reported by Inside Ecology, environmental groups welcomed the water and energy bills but warned that aviation policy and weak reform undermine the package. The water bill focuses on sewage dumping and catchment management, a separate issue from your gas bill, but connected through the same regulatory machinery. The energy bill, however, is the one that matters for your home.
Who qualifies, and who doesn’t
Labour’s energy bill is expected to extend the Boiler Upgrade Scheme (BUS) beyond its current 2028 end date, and potentially raise the grant from £7,500 to £10,000 for heat pumps. The Energy Saving Trust estimates a typical three-bed semi costs £14,000 to install an air-source heat pump, so a higher grant would close the gap. Yet the bill does not mandate a date for ending new gas boiler installations, a gap that the Climate Change Committee has called “critical”. Homeowners on standard variable tariffs should also watch for a potential overhaul of the Energy Company Obligation (ECO4), which funds cavity wall and loft insulation for low-income households. The current scheme runs until March 2026; a new iteration could widen eligibility to the “able-to-pay” market, meaning you might get a grant even if your household income is above £31,000.
What it costs a typical 3-bed semi
Ofgem’s latest price cap, effective October to December 2024, is £1,717 per year for direct debit customers, about 8% below the previous cap but still 40% above pre-2021 levels. The King’s Speech bills do not directly cap retail prices; that is Ofgem’s job. But the energy bill includes provisions to reduce network charges, which make up roughly 16% of a typical bill. If the government shifts some network costs from electricity to general taxation, a typical household could save £60–£100 a year. The catch: those savings assume you have already installed a heat pump or solar panels, because network charges are higher per kWh for electricity than gas. Homeowners who stick with a gas boiler will see little benefit.
What this misses, the aviation blind spot
Environmental groups including Friends of the Earth and Green Alliance welcomed the water and energy bills but pointed out that the King’s Speech contained no aviation tax reform or clean power bill. Aviation accounts for roughly 7% of UK emissions, and the Committee on Climate Change has recommended a frequent flyer levy since 2019. The absence of such a measure means the government is relying on technological fixes, sustainable aviation fuels, that are not yet commercially viable. For homeowners, the indirect effect is on the cost of borrowing for home upgrades. If the UK misses its carbon budgets because aviation emissions are not tackled, the Treasury may impose higher carbon taxes on home energy instead. That could raise the cost of running a gas boiler by £200–£300 a year by 2030, according to Carbon Brief estimates.
What to do and by when
Homeowners should not wait for legislation to pass. The Boiler Upgrade Scheme is open now at £7,500 per heat pump, and applications take about four weeks. If you are planning an extension or major renovation, submit your application before the next price cap review in February 2025, grants are first-come, first-served and the current budget is £450 million. For those on low incomes, check your eligibility for ECO4 insulation through your energy supplier; the scheme closes in March 2026 and funds are running low. The King’s Speech bills will take at least 18 months to become law. Your heating system will not wait that long.
Frequently Asked Questions
Installing an air-source heat pump in a typical three-bed semi in the UK costs around £14,000, according to the Energy Saving Trust. However, the Boiler Upgrade Scheme currently offers a £7,500 grant, and the new energy bill may raise this to £10,000, significantly reducing your out-of-pocket costs.
Ofgem's latest price cap, effective from October to December 2024, is £1,717 per year for direct debit customers. This is about 8% below the previous cap but still 40% above pre-2021 levels, so many homeowners are still feeling the pinch.
The energy bill includes plans to reduce network charges, which make up about 16% of a typical bill, potentially saving you £60–£100 a year. However, these savings mainly benefit homeowners who have already installed a heat pump or solar panels, as network charges are higher per kWh for electricity than gas.
The Boiler Upgrade Scheme currently offers a £7,500 grant for heat pump installations, and the new energy bill may raise this to £10,000. Eligibility is not limited to low-income households, so most homeowners can apply, but the scheme runs until 2028 and may be extended.
ECO4 is the Energy Company Obligation scheme that funds cavity wall and loft insulation for low-income households, running until March 2026. A new iteration may widen eligibility to the 'able-to-pay' market, meaning you could get a grant even if your household income is above £31,000, so it's worth checking for updates.
