Have Octopus prices risen in 2025?
So far in 2025, Octopus prices have gone up twice and down once in line with the energy price cap.
When we talk about energy prices going up and down, we usually mean the prices of standard variable tariffs, which aren’t fixed and can change depending on wholesale market conditions. The amount suppliers can charge per unit of energy used on a standard variable tariff is limited by the Ofgem energy price cap.
The price cap is set four times each year, and the current cap has been set at £1,849 for the period 1 April to 30 June 2025. However, it will fall to £1,720 for the period from 1 July to 30 September.
Octopus promises to keep its own standard variable rate tariff – Octopus Flexible – below the price cap, typically around £15 cheaper. The following table reveals how Octopus’s standard variable rate has compared to the price cap over the past 12 months:
| Time period | Price cap level | Energy Price Guarantee level | Octopus standard variable price |
|---|---|---|---|
| October 2023 - January 2024 | £1,834 | £3,000 | £1,819 |
| January 2024 - April 2024 | £1,928 | £3,000 | £1,913 |
| April 2024 - July 2024 | £1,690 | £3,000 | £1,675 |
| July 2024 - October 2024 | £1,568 | £3,000 | £1,552 |
| October 2024 - January 2025 | £1,717 | £3,000 | £1,702 |
| January 2025 - April 2025 | £1,738 | £3,000 | £1,723 |
| April 2025 - July 2025 | £1,849 | £3,000 | £1,838 |
| July 2025 - October 2025 | £1,720 | £3,000 | TBC |
Remember, the cap doesn’t guarantee the maximum price you’ll pay – it’s based on an average household’s usage. Find out more with our guide to average gas and electricity bills in the UK.
What can I do about Octopus price increases?
Octopus offers a wide range of tariffs, including fixed-price tariffs that lock in your rates to avoid future price rises for 12 months. Unlike some other providers, if you subsequently find the price of energy has fallen below what you’re currently paying, you can switch without incurring an exit penalty.
The easiest way to compare Octopus’s tariffs with those of other major suppliers is to perform an energy price comparison. Find out more with our guide to switching energy supplier or enter your postcode below to run a comparison.

Will Octopus's prices rise in 2025?
The next energy price cap level (from October 2025) is currently projected to rise slightly, according to British Gas's latest predictions. The actual price cap level will be announced in August 2025. Looking further ahead, British Gas forecasts two more increases over the winter and into 2026. Note that the confidence of its predictions diminishes the further ahead you look, and even shorter-term predictions aren’t set in stone due to ongoing uncertainty in the energy wholesale market.
