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).

Frequently Asked Questions

We’re the UK’s only genuine multiservice provider. We help people save on their household bills by bundling their energy, broadband, mobile and insurance into one. We offer guaranteed savings. We’re trusted by over 1,386,585 customers, rated Excellent on Trustpilot and are Which? Recommended.

UW Partners in and around are people just like you, who earn an extra income by introducing others to UW and helping them sign up as customers. They also help people to become a UW Partner and start earning an income by recommending UW to their friends and family.

Yes, of course – over 1,386,585 customers and 70,000 UW Partners already do. We’re also regulated by the energy regulator Ofgem, the telecoms regulator Ofcom, and the Financial Conduct Authority. We’ve been doing business for nearly three decades and are listed on the London Stock Exchange, which means we’re one of the UK’s largest publicly-owned companies.

Your gas and electricity energy services in will go live between two and five working days. We’ll keep you updated on any progress during this time.

Yes – switching energy suppliers in is a simple process. All you need to do is get a quote now to get started; then, we’ll contact your old provider on your behalf and get your services switched over for you. It’s that easy.

No. We work hard to ensure a seamless switching process between energy providers for our customers in so we can guarantee that there’ll be no disruption to your services.

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.
