Save £309 per year: We’ve compared our most popular services with the average price of our main competitors’ equivalent services. By ‘main competitors’ we mean at least three of the largest suppliers by market share who sell a comparable product. The saving shown is based on the average of these competitors’ pricing when compared with an equivalent new UW customer who takes three services – energy (Double Gold variable), broadband (Full Fibre 150), mobile (Unlimited) and pays by direct debit.

Energy: Save on average £48 per year on your energy bills when you take a variable energy service plus two other eligible bundle services vs standard variable tariffs offered by major suppliers (large and medium suppliers as defined by Ofgem), for sale nationally, excl. existing customer tariffs.

Broadband: Switching to UW Full Fibre broadband after your initial contract with current supplier has ended could save you £57.54 a year. This calculation is based on the median UW saving of our Full Fibre 150 tariff vs BT, EE, Plusnet, Talk Talk, Virgin and Vodafone’s closest equivalent tariff (£176.42) over three years. Correct as of 22/09/2026

Holly Green
Glemsford

I first joined Utility Warehouse as a customer, and the £70 I saved each month made a real difference to my family—it meant we could enjoy an extra day out together regularly. I was so impressed by the excellent customer service and the simplicity of managing all our household bills in one place that I decided to become a partner myself, so I could help other families experience the same benefits. When my youngest started nursery, I was looking for a flexible income that would fit around my family life. Now, I earn a full-time income working very part-time hours—perfectly suited to the school run and everything else that comes with family commitments. What I love most is being able to help people save money each month. But I’m equally passionate about showing others how they too can earn an additional income by simply helping their friends and neighbours save money as well!

Hi, I’m Kayleigh. I live in Suffolk’s smallest town, Clare. Four years ago we decided to try country life and couldn’t be happier. I live here with my husband Gary, our two children, Evie and Zach, and Henry the dog. My passion is travel. Everything I do is for my family and to give them the opportunities they deserve. I hope to show the children the wonderful places this world has to offer; UW helps me do that. After losing a business two and a half years ago, UW has changed my life. I work around my children and I love that I have helped so many people on the way. I hope I can watch others achieve their dreams, while I also continue to achieve mine.

No – in a few weeks, we’ll ask you for meter readings, at which point we’ll start billing you for your energy, and your current supplier will stop billing you. So you won’t pay for the same energy twice. Your old supplier will then arrange to send you a final invoice. We recommend leaving your Direct Debit in place until that invoice has been paid.

Smart meters are advanced devices that measure and record electricity and gas consumption in near real-time. Smart meters automatically send us your electricity and gas meter readings through secure wireless networks, so you don’t have to.
