What is Utility Warehouse?
Utility Warehouse is a gas and electricity provider and is part of Telecoms Plus, a UK-based multi-utility business.

As for many energy suppliers, you can find the best deals when you bundle energy with their other services.
Utility Warehouse has won awards for providing good value and customer satisfaction. For example, it promises that its variable energy tariff will always be cheaper than the energy price cap, and that your monthly bill will never have any hidden charges or unexpected price hikes. As of December 2025 their TrustPilot score is 4.3 out of 5.
What kinds of tariffs does Utility Warehouse offer?
-
-
Variable
Utility Warehouse variable tariffs are always cheaper than the energy price cap (currently £1,720 as of December 2025) and has no exit fees.
-
Electric vehicle
Those with electric vehicles can benefit from a tariff that offers cheaper electricity between midnight and 5am each night. Perfect for charging up before your morning commute.
Switch multiple services to save
Like other energy suppliers in the UK, Utility Warehouse offers dual fuel deals.
As well as working out cheaper, getting your gas and electricity from the same supplier can be more convenient and easier to manage, as you only need to deal with one bill and one point of contact.
Utility Warehouse offers the best deals to customers who take two or more services from it. It offers energy, broadband, mobile phone contracts, home insurance, and boiler cover.
What are Free Energy Days?
Utility Warehouse gifts 'free energy days' to new and existing customers who use more than on service. A free energy day is a £5.07 energy credit based on average consumption according to Ofgem.
To be eligible new customers must sign up for two or more services via a partner, and will receive one free energy day a month for three months - that's £15.21.
Existing customers must add two additional services to their account to also be eligible for one free energy day each month for three months. If you add three additional services as an existing customer you get two free energy days a month for a year - that's £121.68.

Our expert says…
Will fixing my rate save me money?
It's worth thinking ahead and bearing in mind that a fixed rate energy deal could save you money during the coming months. Switching to a fixed rate energy tariff can protect you from future energy price volatility and save you hundreds of pounds over the course of the year.
More and more energy providers are releasing tariffs for new customers, so run a comparison and see if you could switch and save money on your energy bills.

What do I need to do if I want to change my current provider?
Changing your energy provider has never been easier. It only takes minutes to run a quote on our site – and you could be up and running with your new supplier as quickly as within five working days.
What happens if my energy supplier goes bust?
It used to be very rare for an energy supplier to go out of business. However, due to the energy crisis in recent years, a number of energy companies have gone bust.
Ofgem, the energy market regulator, will manage any energy company collapses. Thanks to Ofgem’s safety net, even if your supplier goes out of business, your gas and/or electricity supply will never be cut off or interrupted.
In addition to guaranteeing continuity of supply, Ofgem works to move customers of a failed company to the best possible deal. Any existing debit/credit you have with your old supplier will be transferred to the new supplier. And if you want to switch to a different deal with another supplier, you should be able to do so without having to pay an early exit fee.
All UK energy suppliers are regulated by Ofgem.
Do I need a smart meter with Utility Warehouse?
In most cases, Utility Warehouse will encourage or require you to have a smart meter installed, especially if you sign up for a fixed deal. This ensures accurate billing and can unlock extras such as bill credits. Installation is free, and Utility Warehouse arranges it for you.
