UK household energy bills continue to be regulated by Ofgem's quarterly price cap, which sets the maximum unit rate and standing charge suppliers can charge customers on default tariffs. The cap is reviewed and adjusted every quarter, with the July 2026 figure due to be announced by Ofgem in late May or early June 2026.
Energy prices across Europe have been pushed higher in 2026 by disruption to Middle East oil and gas supplies, a factor the Bank of England cited in its April 2026 MPC decision as a reason for caution on cutting interest rates.
What the price cap covers
The Ofgem price cap does not cap total bills - it caps the rate per unit of gas and electricity and the daily standing charge. A household that uses more energy than average will pay more than the cap's headline "typical household" figure. Ofgem calculates the typical annual bill based on a household using 2,900 kWh of electricity and 11,500 kWh of gas per year.
Households on prepayment meters are covered by the same cap rates as direct debit customers following Ofgem's 2023 equalisation decision. The cap applies to domestic customers in England, Wales and Scotland. Northern Ireland's energy market operates under separate regulation.
Should households fix their energy tariff?
Fixed tariffs from energy suppliers offer households a set unit rate for a defined period, typically 12 to 24 months. Whether fixing makes financial sense depends on where the price cap is expected to move over the fix period. When the cap is expected to rise, fixing above the current cap rate may still offer savings versus future variable rates. When the cap is expected to fall, staying on a variable tariff tracks the cap downward.
Price comparison services regulated by Ofgem and the FCA can show households which fixed tariffs are available at current rates. Any fixed tariff offered by an FCA-authorised or Ofgem-licensed supplier should include clear exit fee terms.
How to reduce energy bills
Practical steps that remain effective regardless of the cap level: ensuring the home has adequate loft and wall insulation, switching to LED lighting, using appliances during off-peak hours where a smart tariff applies, setting heating schedules, and checking eligibility for government energy efficiency schemes such as the Boiler Upgrade Scheme or the Great British Insulation Scheme administered through local authorities.
Households on qualifying benefits may be eligible for the Warm Home Discount, administered by energy suppliers under Ofgem rules. Applications typically open in September each year.
