Home Energy takes the top spot this month by offering the cheapest qualifying no-exit-fee tariff at £1,453 a year.
Overview
Quick summary
Our comparison feed confirms the number of qualifying options, their £0 exit fee and representative annual cost. It does not provide the tariff names or full product terms, so check the supplier's current tariff information before switching.
This guide ranks UK energy suppliers based on their cheapest annual tariffs with no exit fees. Choosing a penalty-free deal gives you the flexibility to switch at any time—ideal if a better offer emerges or your current supplier raises its prices.
However, this freedom often comes with a trade-off. Tariffs without exit fees can sometimes cost more annually than standard fixed deals that lock you in for 12 months.
The prices shown are based on a typical East Midlands household paying by Monthly Direct Debit; your bill will vary with your location and energy use.

Frequently asked questions
What does a no-exit-fee energy tariff mean?
A no-exit-fee tariff means you can switch to another energy supplier or change to a different plan without paying a penalty. This gives you the flexibility to move if a better deal comes up.
Are no-exit-fee tariffs cheaper?
Not always. While they give you the freedom to leave without a penalty, suppliers often charge slightly higher unit rates for this flexibility. You may find that fixed tariffs with exit fees cost less over a year.
Can my bills go up on a fixed tariff?
Yes, they can. A fixed tariff locks in your unit rates (pence per kWh) and your daily standing charge for the length of the contract. However, it does not fix your total bill, which will still rise or fall depending on how much gas and electricity you use.
How long does it take to switch energy suppliers?
Switching energy suppliers usually takes around five working days. Your new supplier will handle the switch for you, and your power will not be cut off during the process.
What is the Ofgem price cap?
The Ofgem price cap limits the maximum amount a supplier can charge you for each unit of gas and electricity, as well as the daily standing charge, on a standard variable tariff. It changes every three months based on wholesale energy costs.

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.
