Utility Warehouse launches the UK’s best Unlimited 5G SIM-only mobile deal and generous welcome bonus
London, Monday 14th September 2026: Utility Warehouse has revealed two new mobile tariffs, some of the cheapest on the market, to help people simplify and save on their utilities. Plus, it boosted its new customer welcome bonus of up to £250 Cashback Card credit.
From today, Utility Warehouse’s customers can access market-leading prices on SIM-only deals, when taken alongside other services, giving them more data for less than they’d pay elsewhere. The tariffs are:
Go Unlimited: Unlimited data, calls, and texts, for just £13 a month, the cheapest SIM-only deal on the market*. Customers can also add up to three additional SIMs, for £0 for three months.
Go Essential: 5G connectivity with 10GB of data, for just £6 a month.
These tariffs offer simplicity and great value. And getting mobile alongside other Utility Warehouse services, such as energy, broadband, and insurance, means there is less admin to manage. One clear monthly bill for all of your essential home services together in one place.
And new customers to Utility Warehouse can supercharge their multiservice deal with a welcome bonus**, offering them up to £250 depending on the number of services taken. The bonus is loaded onto the customer’s Utility Warehouse Cashback Card, which lets them earn cashback on everyday spending. Cashback earned is automatically taken off the next monthly Utility Warehouse bill.
"People are tired of clunky, overpriced phone contracts that make life harder than it needs to be," said David Walter, Chief Commercial Officer at Utility Warehouse. "We’re making great value home services simple. Launching our new £13 Unlimited tariff and rolling out a £6 5G plan gives our customers value they can feel from day one."
The new tariffs are available to new customers and existing customers who have yet to sign up for a mobile SIM with Utility Warehouse. New customers are also eligible for a welcome bonus, worth up to £250, when signing for Utility Warehouse services. To sign-up, find your nearest Utility Warehouse Partner here.
