Right now, Openreach is building the UK’s largest full fibre broadband network.

This is nationally significant work, supporting economic growth, regional development and everyday life for millions of people. 

Operating in a highly regulated environment, Openreach works closely with industry partners, governments and communities to deliver a network that’s reliable, fair and future ready.  We have a singular culture that unites all our people: we are customer-first challengers, who are committed, clear and connected. These behaviours unite us as one team to better deliver for our colleagues, our customers, our stakeholders and the country. Joining Openreach means playing a direct role in one of the UK’s most ambitious infrastructure programmes, with real purpose, independence and impact.
