£150 Cashback Card credit

The UW Cashback Card is one of the easiest ways to shrink your bills. Top it up. Use it when you shop. Earn up to 10% cashback. That cashback comes straight off your UW bill.

Even better? Get up to £150 pre-loaded when you join.

And our top Cashback Card holders save an average of £461 a year on their UW bills. Not bad for everyday spending.

The legal bit

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).

UW Price Pledge: Eligible new customers (from 22/04/24) who take 3 or more qualifying services and regularly use their Cashback Card. If a customer doesn’t save with UW (incl. Cashback) in their first year vs their previous provider (or cheapest major provider where applicable), they can apply to claim the UW Price Pledge between 12 – 15 months after their sign-up date; the pledge & no exit fees only applies to qualifying services taken at sign-up. When you claim, we’ll assume an average Cashback Card saving of £160 a year (based on customer usage data from 03.04.23 to 31.03.24, for users who earned Cashback at least at least once a week, excluding promotional activities) or your actual Cashback saving if higher.

What our customers say

Partners in and around Belfast

Larne

month on our bills at the time and I enjoyed being able to help others make similar savings when I joined as a Partner. I’ve never looked back and still enjoy helping others pay less on their everyday bills. Learning to help others do what I do is, and has been, an education, but one I also enjoy. After I was injured at my work and put out to pasture, it was this business which gave me the purpose to continue to help others and I am eternally thankful for it. It’s also given me three holidays and a brand new car.

What’s a UW Partner?

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.

Can I trust you?

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.

How do I switch my broadband?

Switching broadband provider couldn’t be easier. We’ll handle the entire process and it only takes about 14 days. You’ll keep your existing telephone number, and if you don’t have a telephone line we can install one for you.

Do you have to cancel broadband when switching?

No, leave this with us and we’ll let them know you’re switching. However, if you’re currently a Virgin customer, you will need to call them after your line is working with us and ask them to cancel the service.

Can I keep my own broadband router?

Yes, you can. But you’ll need to make sure your router isn’t locked by your previous provider. When you sign up to us, we’ll send you your username and password, so you connect your own router.

With our full fibre broadband options in , your router needs to be Very High-Speed Digital Subscriber Line (VDSL) compatible. If it’s not, it won’t work with our broadband service.

What is a good broadband speed in ?

Unlimited data means that you don’t have a cap on your data allowance each month in and the rest of the UK. There are no restrictions on how much data you use, so you won’t have to worry about using up all your allowance.

Our Unlimited data, calls and texts SIM-only plan is perfect for surfing the internet, taking video calls, or even streaming media, as you can use as much as you need.

What can affect my broadband speed in ?

We’re offering EU roaming as part of our Unlimited tariff, so you can take your unlimited data abroad and use up to 14GB of it at no extra cost. It’s part of our Roam like Home service, which lets you use your allowance in 45 locations across Europe. You can also send texts and make calls back to the UK as you would normally with your allowance. Our Unlimited tariff has no data usage cap when browsing in the UK.

Do UW provide Auto Compensation?

Yes, we do. At UW, keeping you connected is important to us. So we signed up to Ofcom’s Automatic Compensation scheme for Phone and Broadband services. Making sure our broadband and landline customers in get compensation when things go wrong remains a priority.

This means that, if you’re eligible, we offer automatic compensation for those unfortunate circumstances when:

● There’s a delayed repair following the loss of service in
● An engineer misses an appointment
● Your service goes live later than the date we said it would.
