The price cap follows the cost of energy, which changes based on things like supply and demand, the weather, and global events – that’s why it goes up and down. If you’re on a flexible tariff (also known as a variable tariff), your prices are linked to the price cap and move with the market to reflect the actual cost of energy. Our Flexible tariff has always been below the price cap, so you’ll know you’re getting great value.
However, some people prefer fixed rates for peace of mind. If you're on a fixed tariff, your energy price stays the same for a set time – and right now, these offer our cheapest rates. That doesn’t mean your bill will be the same each month – if you use more energy, you’ll pay more – but you won’t be hit with sudden price changes, giving you extra security.
The energy price cap is a limit on the price of energy that suppliers can charge per kilowatt hour. It’s decided by Ofgem and affects customers on variable tariffs (where energy prices change based on the wholesale cost of energy).
Keep in mind that Ofgem’s price cap sets the max amount suppliers can charge for each unit of gas and electricity — not your final bill. The more you use, the more you’ll pay.
Good to know: Octopus is the only large supplier to have never charged the full price cap!

Smart tariffs are a game-changer if you’ve got smart home tech like solar panels, a heat pump, or an EV – or if you’re ready to play a more active role in managing your energy use.
With tariffs like Agile and Tracker, customers get access to daily or half-hourly energy prices, so when wholesale electricity prices drop, so do your bills. As these tariffs are impacted by market volatility, they're best suited to people who can shift their energy use to avoid pricey peaks, often by using smart home tech like solar and batteries.
Octo Assist is a £30 million customer help fund and a collection of support schemes designed to help customers who need it most keep on top of their energy, and keep warm without worrying.

We even loan out thermal cameras to help more customers save heat in their homes — just one of the many ways we're helping people become more energy efficient.
