What should you do now?
Your next step depends on your tariff status. Pick the path that matches your bill today.
You are on a standard variable tariff (SVT)
Your unit rates reset automatically from 1 July 2026. Compare fixed options now so you can avoid defaulting to a higher capped rate.
You are fixed, but your deal ends soon
If your fixed term ends in the next three months, line up your next tariff early. This helps avoid rolling onto SVT at the higher cap level.
You are fixed with exit fees
Do not switch blindly. Compare exit fees against projected savings on your real kWh usage before moving early.

What this can mean for different households
Illustrative impact if the same 13% uplift applied to your annual energy spend profile.
| Household profile | Baseline spend | Annual change | Monthly change |
|---|---|---|---|
| Lower-use household | Around £1,200/year before July | +£156/year | +£13/month |
| Typical household | £1,641/year before July | +£221/year | +£18/month |
| Higher-use household | Around £2,200/year before July | +£286/year | +£24/month |
These are directional examples, not personal quotes. Your actual bill depends on your tariff, meter type, region, standing charge, and real kWh usage.
What changes on 1 July 2026?
The cap is a limit on unit rates and standing charges for default tariffs, not a cap on your final bill total. If your usage is above average, you still pay above average.
This quarter's move is mainly gas-driven. Ofgem says gas-related charges are up around 24%, while electricity-related charges are up around 5%.
The change mainly affects households on standard variable tariffs. Ofgem says around 33 million domestic accounts are on SVT, while around 22 million fixed-tariff accounts are not directly affected until their deal ends.
Should you switch before 1 July?
For SVT customers, rates increase automatically on 1 July, so comparing before then is usually the key decision point.
If you can secure a fixed tariff below the new equivalent level on your own usage profile, you reduce annual cost and exposure to another cap reset.
Standard UK switching typically takes 17 working days. Starting before mid-June gives the best chance of being on a new tariff before 1 July.
If you are on a fixed deal, check exit fees and compare them against likely savings before moving early.
The two price cap figures explained
Ofgem published both £1,862 and £1,663 because they describe different baselines.
£1,862 is the like-for-like comparison to the current £1,641 cap using the previous consumption assumptions. That is the clearest way to see the real quarter-to-quarter increase.
£1,663 is Ofgem's new headline using updated Typical Domestic Consumption Values. Both figures are valid, and your bill still depends on your own usage.
Frequently asked questions
What is the energy price cap from July 2026?
Ofgem confirmed on 27 May 2026 that the energy price cap from 1 July 2026 is £1,663 per year based on updated typical household consumption figures, or £1,862 per year on equivalent consumption to the current cap. The current April-June 2026 cap is £1,641. The rise is 13%.
When does the July 2026 energy price cap start and end?
The new price cap takes effect on 1 July 2026 and applies until 30 September 2026. Ofgem will announce the Q4 2026 cap, covering October to December 2026, by 26 August 2026.
Should I switch energy supplier before the July 2026 price cap rise?
If you are on a standard variable tariff, your bills will rise automatically from 1 July. Fixed deals priced below the new cap level are available now. The standard UK switching process takes 17 working days, so switching before 14 June gives you the best chance of being on a new deal before 1 July. Taupia can compare deals based on your actual usage.
Why are there two different July 2026 price cap figures?
Ofgem published two figures on 27 May 2026. The £1,862 figure is calculated on the existing consumption assumptions and represents the real-terms increase from the current £1,641 cap. The £1,663 figure is Ofgem's new official headline, calculated using updated typical consumption values that reflect the fact that the average household now uses around 7% less electricity and 17% less gas than in 2023. Because the cap controls unit rates rather than total spend, your actual bill depends on your own usage.
