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.

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.

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.

My name is Euan and I am a full time firefighter. I took up UW in 2022 after struggling to make extra cash working on building sites, driving around the country for delivery jobs etc. UW allowed me the freedom of having time at home with my young children and my wife on my days away from the fire service. I've already been able to help family members, friends, colleagues, neighbours save with UW and being able to help them and be rewarded for it has made a huge difference to my family!

How does a SIM only deal work?

A SIM-only deal gives you data, minutes, and texts for a set monthly cost. However, you don’t get a new phone like you would with a mobile phone deal – you just get the SIM.

Can I use my own phone when I join UW?

Of course. You can use our mobile SIMs with any unlocked handset or any phone on the EE network too.

The easiest way to tell if your phone is unlocked is by inserting a different SIM card from another network into your mobile. If you’re able to connect to the internet, make calls, and send text messages, your phone is likely unlocked.

If you don’t have another SIM card from a different network provider, you can also check by going into your phone’s settings.

Can I keep my phone number when I join UW?

Yep, simply contact your previous network provider or text ‘PAC’ to 65075 to get a code which will allow you to bring your current number over to your new SIM. This won’t disrupt your service either. Find out more about how to keep you current mobile number.

Can I use my unlimited data abroad?

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.
