The cap limits unit rates and standing charges for covered default tariffs in Great Britain; it does not cap the total amount a household can pay.
For July to September 2026, Ofgem published £1,862 under the previous typical-consumption values and £1,663 under revised values effective from 1 July. The underlying national-average direct-debit rates include 5% VAT.
What is capped
Rates rather than total consumption. Higher kWh still produce a higher bill.
Two headline figures
The tariff did not become cheaper because the consumption benchmark changed. Always state which Typical Domestic Consumption Values are used.
Who and where
It covers relevant tariffs in England, Scotland and Wales; Northern Ireland is regulated differently.
Regional rates
Network area, meter and payment method can change the figures around the national average.
Quarterly check
Use the rate for the exact bill dates, especially when a bill crosses a cap period.
Frequently asked questions
Are £1,862 or £1,663 maximum bills?
No. Both are typical-use illustrations using different consumption benchmarks; actual cost depends on use and tariff rates.
