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.

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.

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).

I’ve been a UW partner for over 10 years and I love what I do! Me and my team have helped thousands of families save money and time on their bills with some other amazing benefits. I’m also a trainer and a recruiter for UW and I help people from all walks of life create an extra income that doesn’t affect their job. Please get in touch for a chat – I’m happy to help.
My name is James, and I live in Cardiff, South Wales. I originally became a UW Partner, as I was looking for a flexible way to earn some money while studying at university. I’m proud to have helped families across the UK reduce their monthly bills, and I love introducing them to becoming a Partner, as well. I’m able to chat remotely or in person, so please get in touch if you’d like to find out how much you could save with UW or if you’re interested in becoming a Partner. I’m always happy to help!
My name is Sarah and I am married with 2 children, both of which have hearing challenges. Due to struggling with childcare while the children were small, I started UW to allow me to be a full-time parent whilst also earning an income from home. After more than 8 years as a customer and partner, I am able to spend time with my children and help other families do the same. There’s nothing exciting about paying bills, which is why we help you with the boring stuff and make it fun and easy. We live in a small village in South Wales and have helped hundreds of families reduce their monthly spend and have more time with loved ones.
