Cheapest Fixed Energy Tariffs in the UK (July 2026)
The cheapest fixed deal this month costs £1,543 a year from Outfox Energy and comes with a £150 exit fee.
Overview
Quick Summary
As we head into summer and heating usage drops, many households take the opportunity to reassess their energy bills. When considering a fixed tariff, the main challenge is balancing price certainty with flexibility. A fixed deal locks in your unit rates and standing charge for the duration of the contract—typically between 12 and 24 months—protecting you from sudden price hikes.
However, this security requires commitment. If wholesale energy prices fall and a better deal emerges, leaving your contract early often incurs an exit fee. To help you compare your options, we have ranked 30 fixed tariffs available this month. Before switching, always check the contract length and exit fees to ensure the tariff is the right fit for your household.

Frequently asked questions
What is a fixed energy tariff?
A fixed energy tariff locks your unit rates and daily standing charge for the length of your contract. This means the price you pay for each unit of energy will not change, but your total bill will still go up or down depending on how much energy you use.
Should I choose a fixed or variable tariff?
A fixed tariff gives you certainty over your unit rates, which helps if you want to avoid sudden price cap rises. A variable tariff moves with the Ofgem price cap, meaning your rates can go down as well as up, but it usually comes with no exit fees.
What happens if I leave a fixed tariff early?
Many fixed tariffs come with an exit fee, which is a penalty charge for leaving before your contract ends. Some suppliers do not charge this fee, so it is worth checking the terms before you switch.
Will my energy bills stay the same every month on a fixed deal?
No. While your unit rates are locked, your final bill depends on your usage. If you use more heating in the winter, your bills will be higher than in the summer.
How long do fixed energy contracts last?
Most fixed tariffs last for 12 months, but some suppliers offer 15-month or 24-month contracts. A longer contract protects you from price rises for longer, but often comes with a higher exit fee.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
