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.

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).

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 13/01/26. 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 13/01/26.

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.

What our customers say

Partners in and around Harrow

Stanmore

I’m a Utility Warehouse (UW) Partner, I genuinely enjoy supporting others to reduce their bills and make their money work harder for them. Over time, I’ve helped many friends and family save money on their everyday services, savings that can then be redirected towards holidays, a savings pot, or simply easing monthly expenses. Knowing I’ve made a positive difference in people’s lives is what motivates me most. I work well with people and pride myself on being approachable, honest, and easy to talk to. My focus is always on understanding what works best for you, your lifestyle, so I can help you make informed decisions that truly benefit you.

Northwood

I am a UW Partner and I help businesses and households save hundreds of pounds on their utility bills, with substantial savings on their energy, water, telephone, broadband, mobiles, and insurance. I can help corner shops right up to industrial units on the commercial side, and studio flats all the way up to mansions on the domestic side. We cover the whole of the UK, and everything can be done remotely. I’m looking for anyone you know who is trying to cut costs and keep their hard-earned money in their pockets. Please feel free to either call or email me to arrange a non-obligatory chat.

Edgware

I'm a busy mum and left teaching in favour of tutoring, so that I can be available for my children. With the cost of living crisis, I needed an extra income and then I found UW. I signed up as a customer first and saw they genuinely help you save on utilities as a bundle. I was so excited to share this with friends and family so they could save too. It's been 6 months since I've started and it's one of the best choices I've made. I'm working towards a free family holiday, I’ve already earned us cinema luxe tickets and made a whole new bunch of friends along the way.

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.
