Card gives money back against your bill

Utility Warehouse is the brand name of Telecom Plus, and was founded in 2002 as a multi-service provider. Rather than advertising in the traditional way, it grows through a partnership scheme, where partners earn an income for referring new customers.

Its core idea is simple: bundle your household services together, from energy and broadband to mobile and insurance, and manage them through a single bill and account. UW also offers a Cashback Card, which gives customers cashback on shopping at participating retailers, credited against their UW bill.

Utility Warehouse markets itself heavily on value. It came joint first for Best Value for Money in Uswitch’s 2025 Energy Awards, having won the same category in 2024. It also promotes a Price Pledge, under which it says customers who do not save in their first year will get double the difference back, and it offers a contribution towards any early exit fees you face when leaving your current supplier. As with any such offer, it is worth reading the full terms, as these claims and incentives are set by UW and can change.

On renewable energy, Utility Warehouse offers 100% renewable electricity only on its top green tariff, sourced through Renewable Energy Guarantee of Origin (REGO) certificates. Its other tariffs are predominantly gas-based, with a smaller share of renewable electricity. UW plants a tree for every new customer who joins, and funds a number of environmental charities.

For customers who are struggling, Utility Warehouse has a dedicated support page and operates a hardship fund to provide financial assistance to those who need it.

Utility Warehouse tariffs

Utility Warehouse works differently from most suppliers. Its energy tariffs are usually linked to taking one or more of its other services, and the more services you bundle, the larger the discount on your overall bill. This makes the tariffs harder to compare directly, so it is worth checking whether the energy element stands up on its own before signing up for the extras.

Value
A standard variable, energy-only tariff. It tracks the Ofgem energy price cap, so rates change every three months in line with the cap. This is the tariff for customers who want to take only energy from UW.
Gold and Double Gold
Variable tariffs offering discounted rates, but they require you to take energy alongside one or two other Utility Warehouse services.
UW Fixed and UW Fixed Saver
12-month fixed tariffs. They require you to bundle energy with at least one other service, and to have smart meters installed or agree to have them fitted for free.

An EV-specific tariff is also available. Exit fees apply if you leave a fixed tariff early, reported at £75 per fuel as of mid-2026.

Utility Warehouse supports all meter types, including traditional and smart meters, prepayment meters, and multi-rate meters for Economy 7. Smart meters are fitted free of charge, and new customers may be offered a credit towards their bill for having one installed when they join.

How the bundle model works

Unlike most suppliers, Utility Warehouse is built around bundling. You can take energy on its own, but the discounted rates come when you add other services such as broadband, mobile or insurance, all managed through a single bill and account.

This can offer real convenience and value if you want to consolidate your household services. The trade-off is that it makes the energy element harder to compare like for like, so the key question is whether the energy tariff is competitive on its own terms, before the bundle discount is taken into account.

Utility Warehouse customer reviews

Utility Warehouse scores 4.2 out of 5 on Trustpilot, based on over 82,000 reviews, which places it in the Great category. Reviews frequently praise UW’s customer service, and its back-to-back Uswitch Best Value for Money awards reflect how customers rate it on price.

One practical point to weigh up is that its single call centre keeps shorter hours than some larger suppliers, which may matter if you need to reach them at the weekend or in the evening.

Expert view

“Utility Warehouse is genuinely different, and for the right household the bundle model can be great value, especially if you want one bill for energy, broadband and mobile. The thing to watch is that the best energy rates are tied to taking other services, so always check the energy tariff on its own merits rather than being swayed by the bundle discount. And if green energy is a priority, note that only their top tariff is fully renewable.”

Is Utility Warehouse right for you?

Utility Warehouse may suit you if you like the idea of simplifying your household services into one bill and want to earn discounts by bundling. Its value credentials are strong, backed by two years of Uswitch Best Value for Money awards, and the Cashback Card is a useful extra if you shop at participating retailers.

It is less likely to suit you if you want energy on its own at the keenest possible rate, since the best deals are tied to taking other services, or if fully renewable electricity is a priority across all tariffs. As always, compare the energy element on price before you commit.
