The price cap will rise by £332 a year in July, the highest single increase since the energy crisis of 2022. That is not a blip. It is a structural shift.
As reported by BBC News, the typical household on direct debit will pay £1,812 a year from July, up from £1,480 now. That is £151 a month, £28 more than today. For prepayment meter households, the figure is higher still, at around £1,920.
The cap is not a ceiling on your actual bill. It caps the unit price per kWh. Use more energy, pay more. The typical figure assumes 12,000 kWh of gas and 2,900 kWh of electricity a year, a 3-bed semi with two occupants. If your home is larger or older, your bill will be higher.
Who qualifies, and who doesn’t
Every household on a standard variable tariff is protected by the cap. That is about 22 million homes. Fixed-rate deals are returning but still above the cap, the cheapest fix on the market is around £1,650 a year, according to comparison sites. That is £162 less than the July cap, but you lock in for 12 months. If prices fall, you lose.
The catch is that the cap is adjusted every three months. Ofgem will announce the October figure in August. Most analysts expect another rise, possibly smaller, but nobody is forecasting a return to pre-2021 levels. The era of £1,000-a-year bills is gone.
Prepayment meter customers face a separate cap, typically £80-£100 higher per year. Ofgem has pledged to close that gap by 2026, but not yet.
What it costs a typical 3-bed semi
Take a typical 3-bed semi in the Midlands, with a gas boiler and standard appliances. At the July cap, the annual cost breaks down roughly as follows:
- Electricity: 27p per kWh standing charge 60p/day, around £870 a year
- Gas: 7p per kWh standing charge 30p/day, around £940 a year
Total: £1,810. That is before any increase in usage. A cold winter pushes it past £2,000.
For homes with electric heating (storage heaters, heat pumps without a gas backup), the electricity component dominates. A 3-bed semi with electric heating and poor insulation could see £2,500 a year.
The government’s Energy Price Guarantee, which capped bills at £2,500 for 2022-23, is gone. The market is back, and it is unforgiving.
How EPC upgrades can offset the rise
The £332 rise is painful, but it is also a calculator for retrofit value. Every percentage point of energy saved is cash in your pocket.
Energy Saving Trust data shows that a typical semi-detached home with an EPC rating of D can save £200-£300 a year by upgrading to a C through cavity wall insulation, loft insulation to 270mm, and draught-proofing. That nearly cancels the July rise.
Solar panels: a 4kW system on a south-facing roof generates about 3,500 kWh a year, saving £500-£700 on electricity bills at current cap rates. Payback is 8-12 years, but the savings compound as prices rise.
Heat pumps: an air-source heat pump replacing a gas boiler can cut heating costs by 20-30% if the home is well insulated. The £7,500 Boiler Upgrade Scheme grant covers most of the installation cost for most homes.
But the order matters. Insulate first, then electrify. A heat pump in a draughty home costs more to run than an efficient gas boiler. The government’s Great British Insulation Scheme offers free or discounted insulation for low-income households and those in EPC bands D-G.
When to act, and what to do now
The July cap takes effect on 1 July. If you are on a standard variable tariff, you will see the increase in your August bill (bills lag by a month).
Switch to a fixed-rate deal if you can find one below £1,650. Use a comparison site that shows actual annual cost, not just unit prices. Check your direct debit, overpaying by £20 a month now builds a credit buffer for winter, but do not let suppliers hoard your cash without earning interest.
Apply for the Boiler Upgrade Scheme before July if you are considering a heat pump, installer waiting lists are growing. The Great British Insulation Scheme is open now for applications through your energy supplier.
For renters: you cannot replace the boiler or install solar, but you can draught-proof, use thermal curtains, and ask your landlord for EPC improvements. From 2028, all new tenancies will require an EPC of C or above. That gives landlords three years to act.
Households on standard variable tariffs can apply for support through the Warm Home Discount (a £150 rebate on electricity bills) if they receive certain benefits. Eligibility is automatic in most cases, but check with your supplier.
The July rise is not the last. Plan for £2,000-a-year bills as the new normal. Retrofit is no longer a luxury, it is the only hedge against a market that will not come back down.
Frequently Asked Questions
Most analysts expect a further rise in October, though likely smaller than the July increase. Ofgem will announce the October cap on 27 August 2025. The key drivers are wholesale gas prices, which remain volatile due to geopolitical factors, and network charge increases already scheduled.
Yes, but fixed-rate deals are currently around £1,650 a year, £162 less than the July cap. However, if prices fall further, you could be locked into a higher rate. Compare deals carefully using a site that shows estimated annual costs based on your actual usage, not just the headline rate.
