What our customers say

Partners in and around Brentwood

Stondon Massey

Hi, we’re Anil and Faith. We live in Brentwood, Essex, and we’re both retired. We’ve been UW Partners since 2011 and we used to fit it around raising a family and our jobs as an IT consultant and a gardener. It’s great seeing how satisfied people are with UW’s services, and so rewarding helping people reduce their monthly bills. Please get in touch if you’re curious how much you could save with UW or if you’d like to earn some extra income on your own terms as a Partner. We’d be happy to help!

Brentwood

I’m in Brentwood, and initially wanted to save money on our bills, so we switched all our services to UW. I couldn’t believe the monthly savings, and loved the way I could reduce my bills every time I spent my own money! I was hesitant to join as a Partner at first, as it sounded too good to be true. Getting paid while I help people save money? There must be a catch somewhere… But there wasn’t, and 18 months later I’ve built the most rewarding business, where all I do is help people save and earn. Such a great position to be in. Let’s have a chat and see what I can do for you.

Stondon Massey

Hi, and welcome to UW. I am a dedicated person, with a strong ethos and always motivated at what I do. I enjoy working with others, and am always happy to help and go that extra mile. Cheerful. Curious. Driven. Empathetic. Energetic and Enthusiastic.

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?

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.

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.

What does unlimited data mean?

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.

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.

What is a family plan?

A family plan is a special family SIM-only deal that covers multiple SIMs. With a family plan, you can choose a deal that ensures your whole household is connected, all as part of a single convenient bill.
