The energy price cap rises tomorrow, adding about £63 to the typical household’s annual bill. That is the third increase in twelve months, and for a 3-bed semi on standard variable tariff, it means roughly £1,738 a year before any usage changes. The clock is ticking, but there are still things you can do before the new rates bite.
As reported by the Sun, households have hours to act. But the real question for homeowners is not how to dodge a single price rise, it is how to stop being exposed to them in the first place.
What you can do in the next 24 hours
First, submit a meter reading today. If you do not, your supplier may estimate your usage and charge you at the higher rate for energy you actually used at the lower rate. Ofgem recommends this step every time the cap changes. It takes five minutes and costs nothing.
Second, check if you can fix your tariff. The best fixed deals on the market are currently around 5% below the new cap, according to comparison sites. But they are disappearing fast. If you are on a standard variable tariff, a fix could lock in savings for 12 months. The catch: some fixes come with exit fees, so read the small print.
Third, claim any grants you are entitled to. The Warm Home Discount gives £150 off your electricity bill for low-income households. The deadline for applications varies by region, but many are still open. Check with your supplier or on gov.uk.
Why the cap is not the real problem
The price cap is a ceiling, not a floor. It limits how much suppliers can charge per unit of energy, but it does nothing to reduce how much energy you use. A typical home loses 25% of its heat through the roof and walls, according to the Energy Saving Trust. That is energy you pay for and then throw away.
Insulation is the single most effective upgrade for reducing bills. Loft insulation costs roughly £300–£500 for a typical 3-bed semi and can save around £200 a year. Cavity wall insulation costs more, typically £1,000–£2,000, but saves £300 a year or more. Both improve your EPC rating by at least two bands, which matters when you sell.
Draught-proofing is even cheaper. Strips for windows and doors cost under £50 and can save £60 a year. It is not glamorous, but it works.
What the next cap rise means for heat pumps and solar
The rising price cap makes the case for low-carbon heating stronger. A heat pump uses electricity to move heat from outside into your home, and it can deliver three to four units of heat for every unit of electricity. At current electricity prices, that makes it cheaper than gas heating for many homes, especially if you have solar panels.
The Boiler Upgrade Scheme offers £7,500 off a heat pump installation in England and Wales. That grant, combined with rising gas prices, means a heat pump can pay for itself in 7–10 years. Solar panels add another layer: they generate electricity during the day, reducing what you buy from the grid. With the Smart Export Guarantee, you can sell surplus power back at a fixed rate.
But the upfront cost is high, typically £7,000–£11,000 for a heat pump and £5,000–£8,000 for solar. The grants help, but they are not infinite. Applications for the Boiler Upgrade Scheme are capped at 50,000 per year, and demand is rising.
Who qualifies, and who does not
Households on standard variable tariffs are the ones hit hardest by the cap rise. Those on fixes are protected until their deal ends. But anyone can take action now.
Low-income households can apply for the Warm Home Discount, and those on prepayment meters should check if they qualify for the £200 Alternative Fuel Payment if they use oil, LPG, or biomass. The government’s Help for Households page lists all current schemes.
For homeowners planning upgrades, the key question is: can you afford the upfront cost? If not, look at interest-free loans from the Energy Company Obligation (ECO4) scheme, which funds insulation and heating upgrades for low-income households. The scheme runs until 2026.
The cap rise shows energy prices are not coming down soon. The smartest move is to stop being at their mercy. Submit your meter reading, fix your tariff if you can, and start planning the upgrades that will cut your bills for years.
Frequently Asked Questions
Not always. Some fixes have exit fees and may be higher than the cap if wholesale prices fall. But with the cap rising, most fixes currently on offer are below the new level. Compare the unit rates and standing charges, not just the headline annual figure.
Loft insulation saves roughly £200 a year on a typical 3-bed semi, cavity wall insulation saves around £300 a year, and draught-proofing saves about £60. The exact savings depend on your home's size and current efficiency. The Energy Saving Trust has a free online tool to estimate your savings.
