Utility Warehouse is one of the oldest energy firms besides the traditional six, having been set up in 2002.
It currently has over 650,000 customers across the services it sells, all of which are bundled into one bill. It says this approach 'saves families time and money by simplifying their home services’.
Utility Warehouse doesn’t advertise heavily, but relies on agents and customer recommendations instead. Its 45,000 partners (or agents) get incentives to sign up new customers.
Besides gas and electricity, Utility Warehouse sells contracts for home phone, mobile, broadband and home insurance. It bundles them into one monthly bill. Customers can benefit from discounts the more services they buy from Utility Warehouse.
It also replaces light bulbs with LED bulbs for free for customers who buy all of its services or take out its energy bundle.
Utility Warehouse customers can get a cashback card, which earns cashback of up to 7% at a range of shops and online retailers (how much depends on the retailer). The cashback you earn is taken off your monthly bill.
Utility Warehouse came 7th out of 25 energy companies rated by 7,460 members of the public in the annual Which? energy customer survey.

Although Utility Warehouse received an excellent customer score, we couldn't make it a (WRP) for energy as it scored below average in our procedures assessment and had to make an Ofgem redress payment for overcharging customers in January 2020.
It scored an average three stars for customer service and value for money. No company achieved the top rating of five stars for customer service this year and only was rated five stars for value for money. We didn't get enough responses to rate how well it handles complaints.
Utility Warehouse receives low levels of complaints according to data from the energy regulator Ofgem, but it’s not the speediest firm to resolve them – less than half were resolved within two days in the first six months of 2020. However, almost all of the complaints it received were resolved within eight weeks.
They answer the phone quickly, are polite and deal with things quickly.
My bill is so easy to understand. They make it all so clear.
Utility Warehouse’s business model is unique, with some customers also working as ‘agents’ to recruit new customers and earning money by doing so. These partners might give a rosier view because of that relationship but there were only five out of the 66 Utility Warehouse customers in our survey this year, which isn't enough to affect its score.
When we included Utility Warehouse in our snapshot investigation into customer waiting times, it picked up the phone in 2 minutes 16 seconds, significantly faster than the median average of all 31 firms we called (5 minutes 57 seconds).
Pros: Single monthly bill bundling all utilities
Cons: You’ll need to buy multiple services to get the cheapest deals, which might not work for everyone
Yes, if you have a traditional prepayment meter. If you have a smart prepayment meter, Utility Warehouse will need to change it into 'credit mode'. This means that you'll get monthly bills instead and won't be able to pay-as-you-go.
Prepayment customers can top-up at PayPoint, Payzone or Post Offices.
