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 (Ultra), mobile (Unlimited) and pays by direct debit multiplied by the number of customers in the applicable area.

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 13/10/25. Contact us to verify.

Broadband: Switching to UW Ultra broadband after your initial contract with your current supplier has ended could save you £45 a year. This calculation is based on the average UW saving of our Ultra tariff vs BT, EE, TalkTalk and Vodafone’s closest equivalent tariff over three years (£238). Correct as of 29/09/2025.

Mobile: Save £183 with Unlimited Max 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 10/10/2025. Excludes offers and promotional tariffs. Additional SIMs charged at £0/month until 31/03/2026. From 01.04.2026, each additional SIM will be charged at £10/month. Terms apply.

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 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).
