How it works
How the price cap works
Ofgem sets a maximum unit rate (p/kWh) and standing charge (p/day) each quarter — separately for electricity and gas. It applies to standard variable tariffs (default tariffs); fixed-rate deals can be either above or below it.
Where to find your kWh
Check your last annual statement — every supplier shows a 12-month total. Or your in-home display (IHD) for smart meters. Without those, Ofgem's typical use is 2,700 kWh electricity and 11,500 kWh gas for a medium gas-heated home.
Standing charge is fixed
You pay the daily standing charge whether you use any energy or not. For a low-use home it can be 30-50% of the total bill — which is why Ofgem has been consulting on rebalancing standing charge vs unit rate.
Direct Debit vs Standard Credit
Direct Debit is the cheapest payment method under the cap. Standard Credit (pay-on-bill) costs more because suppliers absorb the bad-debt risk. Prepayment was rebalanced to roughly match Direct Debit from 1 April 2024.
Region matters
There are 14 regional caps. Our calculator uses a GB average — your actual bill can be ~5% above or below depending on whether you're in the cheap regions (East Midlands, Yorkshire) or expensive (Merseyside, North Wales, South Scotland).
Beyond the cap
Some fixed deals from suppliers undercut the cap (great if you can lock in before prices rise). Smart meter time-of-use tariffs (Octopus Agile, EDF GoElectric, etc.) can save significant amounts for households able to shift usage off-peak.
