Frequently Asked Questions
Who is the cheapest energy supplier in the UK right now?
As of February 2026, Home Energy remains the joint-cheapest overall supplier with their variable tariff priced at approximately £127 per month. For fixed deals, Outfox The Market has dropped their rates to match this, offering a fixed tariff at around £127 per month.
Who is the cheapest big energy supplier?
E.ON Next is currently the cheapest major supplier with their 14-month fixed tariff costing roughly £133 per month. For a standard 12-month fix, Octopus Energy is the cheapest option among the giants at around £136 per month, followed by OVO Energy at £139.
Will energy bills go up or down in 2026?
The Price Cap rose slightly in January 2026 to £1,758 per year. However, analysts currently forecast that the Cap will fall in April 2026 (by roughly 6% to £1,652) following announcements in the Autumn Budget and changes in wholesale costs.
Is it better to fix my energy tariff now?
Currently, the cheapest fixed tariffs (around £127-£133/month) are significantly cheaper than the January Price Cap (~£147/month). Even with the forecast drop in April, these fixed deals remain very competitive and offer immediate savings.
Do I have to pay exit fees if I switch?
It depends on the supplier. Octopus Energy is unique among the big suppliers for having £0 exit fees on its 12-month fixed tariff. Most other suppliers, including E.ON Next and Outfox The Market, charge between £100 and £150 per fuel to leave a fixed contract early.
Which supplier has the best green credentials?
Ecotricity and Good Energy are widely considered the “greenest” as they invest heavily in building new renewable generation. Among the major suppliers, Octopus Energy and E.ON Next both provide 100% renewable electricity as standard.
Do I need a smart meter to get the cheapest rates?
Often, yes. Many of the very cheapest deals, including tariffs from Fuse Energy and Octopus Energy (like their Tracker tariff), require a smart meter to function. It allows suppliers to buy energy more efficiently and pass the savings on to you.
Why is Utility Warehouse often recommended?
Utility Warehouse offers some of the lowest energy rates (e.g., £128/month) but only if you bundle other services like broadband or mobile with them. If you are willing to switch multiple services, the total household savings can be substantial.
How long does it take to switch energy supplier?
Switching is faster than ever. Under the new Faster Switching rules, a switch can often be completed in as little as 5 working days, though most suppliers aim for around 10-14 days to ensure all billing data is correct.
What happens if my energy supplier goes bust?
Your supply will never be cut off. The regulator, Ofgem, will automatically move you to a new “Supplier of Last Resort.” Your credit balance is protected, so you won’t lose any money you have built up in your account.
