Cashback: you can earn unlimited cashback at the relevant % from our retail partners each month. Purchases from other retailers are eligible for cashback of 1% on spend, subject to cashback caps which vary depending on the number of services you have taken out. You are only eligible to receive the 1% cashback at other retailers if you are not engaged in debt collection proceedings with UW – and have at least one of the following services live at the time of billing: Mobile, Broadband (Broadband and/or Home Phone) or Energy. See our Cashback Card terms and conditions here.

Cashback Card Trial: Get three months free cashback on everyday spending at major retailers. £3 per month after trial – no contract, cancel any time. See terms and conditions here.

Cashback Card Credit: New UW homeowner and tenant customers only. Welcome Bonus (£50-£150) based on Bundle Services taken at sign-up (excludes Home Insurance). Direct debit required. 12-month clawback applies if Bundle Services cancelled. Energy or Broadband required for £100/£150 Bundle Service bonus. For full terms click here.

Cashback Savings: Calculated using the average cashback earned between 01-01-2024 to 29-12-2024 (52 weeks) by the top 10% of active account holders (customers who used their card at least once a week during this period). This figure excludes customers who won 100% cashback through the Cashback Magic promotion.

The UW cashback card is issued by PSI-Pay Ltd pursuant to a license by Mastercard International Incorporated. PSI-Pay Ltd is regulated by the Financial Conduct Authority (FCA) under the electronic Money Regulations 2011 (FCA register number 900011) for the issuing of electronic money. Mastercard is a registered trademark, and the circles design is a trademark of Mastercard International Incorporated.

Our cashback card provider PSI-Pay Ltd is an authorised e-money institution. E-money is not subject to Finance Services Compensation Scheme protection in the way bank deposits are, but it is subject to “safeguarding” requirements. In the unlikely event of insolvency, this means there will be a pool of funds from which cashback card customers would be repaid (subject to certain deductions for associated insolvency costs).

Multi Service Savings Estimate: 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 17/04/26. Contact us to verify.

Broadband: Switching to UW Full Fibre broadband after your initial contract with current supplier has ended could save you £44 a year. This calculation is based on the average UW saving of our Full Fibre 150 tariff vs BT, EE, Plusnet, Sky, Talk Talk, Virgin and Vodafone’s closest equivalent tariff (£134.45) over three years. Correct as of 17/04/26.

Mobile: Save £182 with Unlimited Max compared against the closest equivalent 30 day rolling unlimited data tariffs across EE, GiffGaff, O2, Three and Vodafone over a 12 month period. Price correct as of 16/04/2026. Excludes offers and promotional tariffs.

Additional SIMs charged at £0/month for six months, then £10/month each. Terms apply.

Hi, I’m Marina , a busy mum of a boy and a wife , living in Hythe, Southampton. How did my UW journey begin? For many years I worked in construction, but after developing two chronic conditions I had to take long-term sick leave. I needed a way to earn an income that wouldn’t worsen my health. Joining UW has given me a flexible opportunity to stay financially secure and feel productive again. If you are interested in working with me while helping your friends and family save money on their bills, send me a message and I will show you how.

Hi everyone! I’m Cassie; a Registered Nurse and Health Visitor. I recently moved to Portugal for 2 years as my partner is completing a project here, and I decided to begin training to become a Health Coach. I LOVE being outdoors and active, especially if that involves a rustic cabin with my dog (baby). Equally, I LOVE a bottomless brunch and ALL food! I joined UW in late November 2024 with the aim of being able to make money wherever and whenever, but I honestly love it and I’ve never looked back! I’ve managed to save so many friends and family money on their household bills, and I can’t wait to help others! I also have a growing team and it feels amazing to support others to do the same!

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.
