Cheapest Energy Suppliers in the UK (July 2026)
The cheapest dual-fuel deal this month costs £1,507 a year — a variable tariff from Home Energy with no exit fee.
Overview
Quick Summary
During summer, when heating usage typically drops, many households start looking for ways to reduce their upcoming winter bills. When comparing energy deals, the main choice is between the price certainty of a fixed tariff and the flexibility of a variable or tracker option. Fixed tariffs lock in your unit rates for a set period, shielding you from sudden price hikes, though they often carry an exit fee if you leave early. Conversely, variable and tracker tariffs fluctuate with wholesale energy costs or the price cap, meaning your bills can rise or fall. Since contract lengths and exit fees vary across suppliers, always check the terms carefully before making a switch.

Keep in mind, however, that it carries a £150 exit fee if you decide to leave early.
Fuse Energy also offers a competitive 15-month fixed deal at £1,563 a year, which is £56 more than the cheapest overall tariff but comes with a lower £100 exit fee.

Frequently asked questions
What is a fixed energy tariff?
A fixed tariff locks in your unit rates (pence per kWh) and standing charge for the length of the contract. It does not fix your total bill, which still goes up or down depending on how much energy you use.
Will I pay an exit fee if I switch?
This depends on your tariff. Many fixed tariffs charge an exit fee if you leave before the contract ends. Variable tariffs often do not have an exit fee, but tracker tariffs can carry one, so always check the terms before you switch.
Are tracker tariffs cheaper than fixed deals?
Tracker tariffs can be cheaper when wholesale energy prices fall, as your unit rates move with the market. However, if wholesale prices rise, your bills will go up, whereas a fixed deal protects you from these increases.
Do I need a smart meter to get the cheapest deal?
Many suppliers now ask you to have a smart meter installed to access their cheapest fixed or tracker tariffs. If you do not have one, you can usually still switch, but your options might be more limited.
How long does it take to switch energy suppliers?
Switching energy suppliers usually takes around five working days. Your new supplier will handle the move, and your gas and electricity supply will not be interrupted during the process.

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.
