The typical UK household paid £1,738 for gas and electricity in 2023, nearly double the pre-crisis average. Yet the government’s latest energy bill support package, debated in Parliament this week, focuses almost entirely on smoothing price volatility rather than fixing the root cause: leaky homes that waste heat.
As Politics Home reports, the package includes temporary discounts and deferred payments, welcome relief for households struggling with Ofgem’s price cap, which rose 5% in January. But relief is not reform.
Why volatility masks a deeper problem
Energy prices swing because the UK imports over 50% of its gas, and global markets are unstable. The government’s own Net Zero Strategy admits that poorly insulated homes cost the NHS £1.4 billion a year in treating cold-related illnesses. Yet the support package allocates zero new funding for insulation or heat pump grants beyond existing schemes like the Boiler Upgrade Scheme.
The catch is that every pound spent on temporary bill support is a pound not spent on permanent efficiency. A typical 3-bed semi with cavity wall insulation and loft insulation saves around £300 a year on heating, a saving that compounds year after year, regardless of price spikes.
What a typical 3-bed semi could save
Energy Saving Trust data shows that upgrading from an EPC rating of D to C cuts annual bills by roughly £400. Installing an air-source heat pump adds further savings if the home is well-insulated first. The Boiler Upgrade Scheme offers £7,500 towards a heat pump, but take-up remains low, partly because homeowners fear installation costs and disruption.
Yet the numbers stack. A heat pump running on the current electricity tariff costs about the same per kWh as a gas boiler at 10p/kWh versus 7p/kWh for gas, but with a coefficient of performance of 3–4, the effective cost per unit of heat delivered drops to 2.5–3.3p. That’s half the cost of gas heating.
The policy gap: grants that don’t reach the right homes
Ofgem and the Department for Energy Security and Net Zero have confirmed that the Great British Insulation Scheme has reached only 30% of its target homes since launch. The support package’s temporary measures, like the £200 winter fuel payment expansion, help in the short term but do nothing to improve EPC ratings for the 10 million homes rated D or below.
Homeowners on standard variable tariffs can apply for the Boiler Upgrade Scheme through gov.uk. But eligibility is means-tested for some grants, and application windows close fast. The real action for most households is to book an energy audit now, before winter demand pushes up installation prices.
What to do by when
Households on standard variable tariffs can check eligibility for the Great British Insulation Scheme via gov.uk. Applications for the Boiler Upgrade Scheme remain open until March 2027, but installers’ lead times are already 6–8 weeks. For those considering solar panels, the Smart Export Guarantee pays 5–15p per kWh exported, a decent return if roof orientation and shading suit.
The government’s next budget must decide: more temporary sticking plasters, or a serious retrofit programme. Homeowners should act now, not wait for policy.
Frequently Asked Questions
No. The package focuses on short-term bill discounts and deferred payments. For heat pump funding, you need the Boiler Upgrade Scheme, which offers £7,500 off installation. Check eligibility at gov.uk.
Energy Saving Trust estimates a typical 3-bed semi saves £300–£400 a year after loft and cavity wall insulation. That saving locks in regardless of future price cap changes.
