About Three UK

Hero image for Three UK

Life needs a big network.

Three UK is a big network for the little or life-changing connections that make life richer. Our brand embodies the strength of our network and how we can provide better connectivity every day for every customer.  We’re proud to be the UK’s fastest 5G network (Ookla, 2021).

Three UK is the official sponsor of Chelsea FC men’s and women’s teams as well as Channel 4’s Gogglebox. We’re also a proud partner of Samaritans, where we will use the strength of our network and technology to connect 1 million people to emotional support.

Our people make us who we are. We’re a diverse and inclusive bunch, and it’s important you can feel you belong here. We value everybody for who they are and what they bring to the table, supporting one another as we continue to deliver for our customers.

Our teams in Technology, Commercial, Business, Finance, Legal and Programme Management are looking for graduates to join us in September 2022.  

Are you in?

Careers that count

We're looking for people who want to make their careers count. We want positive, ambitious candidates with a knack for collaboration. We want energy, and an eagerness to learn from the top talent in technology. You'll learn, you'll grow, and with expert mentoring and training you'll do it in a way that's always connected to real projects. You won't be making the tea, you'll be making decisions, creating change and building a better experience for our customers.

Training that matters

We don't think learning should stop after uni. That's why we've put together a graduate programme that gives you the skills to excel at Three and beyond, and we'll give you the tools and support to reach your full potential. You'll experience hybrid working life from home and our brand new head office in Reading and see first hand what makes Three tick. You'll work on daily tasks in your department, and you'll have CSR and business projects to tackle with your fellow graduates - there's always a fresh challenge around the corner. Our graduates will also experience opportunities to network and develop their abilities in teambuilding sessions (and of course have fun at special social events too). Some of our graduate roles also support you gaining a professional qualification, such as CIMA or ACCA for our Finance graduates.

Perks galore

We're happy when you're happy because that's when we do our best work together. Along with the usual great stuff like a competitive salary, pension and fabulous colleagues, you'll have 28 days holiday (plus public holidays and up to 3 personal days), the opportunity to earn a bonus based on performance, a wicked recognition scheme and of course a phone and unlimited plan on Three.

Come join us!

Sounds good eh? We'll be taking applications for the September 2022 graduate programme soon.  Our non-Technology roles will open in November 2021, Technology roles will open in January 2022. Applying is simple, just visit our careers page to get started.
