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. Based on Ofgem’s typical domestic usage. Payment by Direct Debit. Correct as of 22/09/2026. Contact us to verify.

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

Mobile: Save £204 with Go Unlimited compared against the average of the closest equivalent 30 day rolling unlimited data tariffs with the four major network providers over a 12 month period. Price correct as of 22/09/2026. Excludes offers and promotional tariffs.

I have been a UW customer for around a year and have always been incredibly impressed with the services they offer, particularly the UW Cashback Card! When the UW Partner who introduced me suggested I become a Partner too, it was an easy ‘yes’! I have been a teacher for 25 years, and it feels like a part of my DNA to help people. I have found saving friends, family and others in my local community money and time through UW has been extremely rewarding. I am a keen traveler and love nothing more than spending time with my husband and dogs, travelling in our motorhome. Utility Warehouse has given me the time and flexibility to do all of that and more. Please do contact me to see what UW can do for you!

Hi! I’m Lili I am currently on maternity leave with my second baby in two years. I started UW in 2025 to help fund me going back to my social work day job part-time. Now, it is saving my second maternity leave, giving me extra time with my boys and paying for little activities and treats. We live in Gosport on the South Coast and we spend every day by the beach. I have been a UW customer for years so when the opportunity came up to become a partner, I am so glad I said yes. I love that I am able to provide for my babies whilst helping my family and friends save money. I’d love to help more people by helping them with their bills or welcoming them into my team Please do send a message!

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.
