Energy price cap
The energy price cap increased on 1 April 2025, leading to higher energy costs for customers on variable tariffs.
Our fixed tariffs are currently cheaper than the price cap, so you could save on your bills by switching from a variable to a fixed tariff with us.

What is the energy price cap and how does it work?
The price cap, introduced by the government in 2019, limits the rates for customers on standard variable energy tariffs. The energy price cap is set by Ofgem every January, April, July and October. It places a maximum amount you'll pay per unit of energy you use, and the daily standing charge that covers the distribution cost of getting gas and electricity to your home.
It doesn't cap your total bill - the more energy you use, the more you'll pay.
How does Ofgem decide what the price cap will be?
Ofgem sets the price cap by working out how much it costs energy suppliers to supply you with gas and electricity. These costs cover things like buying wholesale energy, maintaining supply pipes as well as wiring and operating costs.

Energy prices increased on the 1st April 2025
On 1st April, Ofgem raised the price cap to £1849 per year. The next price cap will be announced on 27th May, covering the period from 1st July to 30th September.
What can affect our energy price cap predictions?
The energy market has been more stable recently, but surprises can happen. Global politics play a big role in energy prices. For example, if conflicts in Ukraine, or the Middle East worsen, wholesale gas prices could go up. This would eventually mean higher bills.
There’s ongoing talks about how the next price cap is calculated, and other energy rules which could affect prices in 2025, changing these predictions.
We’ll keep these forecasts updated every month to help you understand if a fixed or variable tariff would be best for you.

What do I need to know about the price cap?
The price cap doesn’t apply to fixed tariffs
If you’re on a fixed tariff, the price cap won’t affect you as your prices are locked in for the length of your contract. We won’t increase the price you pay, unless the government increases VAT.
You can check what tariff you’re on in your online account.
Send us monthly meter reads for accurate bills
It’s quick and easy using our app or in your online account.
We use your meter readings so we can send an accurate bill or statement based on your energy use. If we don't receive your readings, we'll make estimates based on typical energy use, which could result in a higher bill than necessary.
When will my Direct Debit change?
Your Direct Debit amount doesn’t adjust automatically when tariff prices change.
If price cap rates are going down, there may be other reasons why we may increase your Direct Debit payments, such as matching the cost of your ongoing average energy use. Also, if your account has a negative balance, we may increase your payments to get your account back to a positive balance.
When will my prepayment meter prices change
Electricity key meters
If you have a meter that you top up with a key at Payzone or Post Office, to get the new prices you need to top up on or after 1st April. Your meter will have the new prices once you've put the key back in your meter.
Pay As You Go smart meters
We know that some of our smart meters won't get the new prices no matter how much we try. If we can't fix yours after three months, we'll send you a cheque for anything you've been overcharged.
Smart Energy Monitors
Some Smart Energy Monitors (SEM) won't update with the new prices, so the estimated cost of energy they show will be wrong. Your bills and Direct Debits will be accurate with the new prices. We’ll keep trying to fix your SEM so it updates correctly.

Terms and conditions apply. You could save by choosing our fixed tariffs instead of our Standard Variable tariff, which is governed by Ofgem’s price cap. Savings based on average domestic gas and electricity energy consumption values (gas: 11,500kWh, electricity: 2,700kWh). The exact savings achieved will vary depending on your energy use. Our customers taking part in PeakSave are saving £24 on average per year. PeakSave average savings per household up to 30th September 2024. If the price cap falls after April 2025, you could pay more for your energy with a fixed tariff. See our latest predictions for the price cap. Read more information on how homes could save with British Gas.
Predicted prices based upon a customer paying by Direct Debit and Ofgem’s typical domestic consumption values (TDCVs) which are set at 2,700 kWh per year for electricity, and 11,500 kWh per year for gas. Our price cap predictions follow Ofgem’s price cap methodology, and we apply our forecasts of other costs to predict future price cap levels. Our prediction will change based on changes in the cost of wholesale energy for future periods.
