July 2026 Ofgem Price Cap: What Changes on 1 July?
Ofgem confirmed that the price cap for standard variable tariffs (SVT) rose about 13.5% like-for-like on 1 July 2026; the current cap headline is £1,663/yr on Ofgem’s updated typical-use basis. Unit rates from 1 July will be:
- Electricity: 26.11p/kWh + 57.19p/day standing charge (up ~5%)
- Gas: 7.33p/kWh + 29.04p/day standing charge (up ~24%)
Around 22 million accounts (roughly 40% of the market) are already on fixed deals and will not see this rise. If you are on a standard variable tariff, you will pay the higher rates automatically from 1 July unless you switch now. A typical home using 2,500 kWh of electricity and 9,500 kWh of gas per year will pay an extra £18 to £25 per month under the current cap.

Sign-Up Bonuses, Loyalty Rewards and Exit-Fee-Free Deals
Beyond the unit rate, suppliers compete on extras that can add further value to a switch:
Exit-Fee-Free Switching
Almost all current fixed deals carry no exit fees, meaning you can leave early without penalty if a better deal emerges. Always confirm this before signing up.
Referral Credits
Octopus Energy offers a referral bonus (typically £50 per referral) to both the referrer and new customer. Ask friends or family for a referral link before switching.
Smart Meter Tariffs
Several suppliers offer cheaper off-peak rates if you have a smart meter — ideal for EV owners or those who can shift usage to evenings and weekends.
Green Energy Options
Ecotricity and Good Energy offer 100% renewable electricity tariffs. These tend to sit slightly above the cheapest fixed deals but provide full green certification.
