Is Utility Warehouse legit?
LegitThere is nothing fly-by-night about Utility Warehouse, a genuine UK multi-service supplier, yet its promise to pay double the difference if you don't save has conditions. It only covers new customers with three or more services who use the Cashback Card regularly, and the claim must be made 12 to 15 months after sign-up.
What we checked
- Brand of London-listed Telecom Plus
- Parent company founded in 1996
- Ratings on other review websites: 4/5
Watch out for
- Leaving a fixed energy tariff early, when exit fees apply, such as £75 per fuel on UW Fixed Start.
- A service added after joining, which falls outside the savings promise and its no-exit-fee terms.
- A Cashback Card that starts costing a monthly fee once the free three-month trial ends.

How do I contact Utility Warehouse customer service?
Utility Warehouse customer service is on 0333 777 0777, the number its complaints page gives for raising a complaint, and the help section of the Utility Warehouse website has a contact page with other ways to get in touch. Have your account number ready, say which service the problem is about (energy, broadband, mobile, landline or insurance), and ask for a complaint reference number. If a Partner signed you up, the complaint still goes to Utility Warehouse itself.
Wrong bill on one of your services? Start your complaint here too, and we push it out to Utility Warehouse through emails, social media and printed letters.
How do I escalate a complaint with Utility Warehouse?
The Utility Warehouse complaints page sets out how to escalate: if customer services cannot settle the complaint, write to the Customer Escalations Team at the head office in London, quoting your complaint reference, and the complaint passes to a specialist in its complaints team. If that does not settle it, the same page gives an email route to the chief executive, asking for your account number, your full contact details and a summary of the issue. The head office address is in the contact details at the top of this page.
Utility Warehouse asks customers to keep making their regular payments while a complaint is open, which also keeps the dispute on the amount you are actually challenging. Keep a dated copy of every letter and email.
How do I leave Utility Warehouse?
To leave Utility Warehouse, first check which services you have and whether any carry a minimum term or a charge for leaving early, which is most likely on broadband and mobile. For energy, switching to a new supplier normally ends the Utility Warehouse supply without you cancelling it yourself; for a mobile number, ask the new network to port it so you keep the number; for broadband, ask the new provider how the switch works so there is no gap in service.
Tell Utility Warehouse which services are leaving and ask for written confirmation, give meter readings on the switch date, and check the final bill and any credit balance that should be refunded to you.
Can I complain to the Energy Ombudsman about Utility Warehouse?
Yes, for gas and electricity: the Energy Ombudsman handles disputes between customers and energy suppliers in Great Britain, and the Utility Warehouse complaints page names it for energy complaints. The Energy Ombudsman generally expects Utility Warehouse to have had the chance to put things right first, so keep a record of every call, letter and reference number.
Energy bill or a direct debit in dispute? Bring it through our complaint process: our trained AI opens a case for you and keeps coaching you on what to reply and when to push again.
