Robert Finnegan, Chief Executive of Three UK, said:

“I am really pleased with this set of results which have delivered our strongest customer contract growth since 2012. We are also seeing strong performance in new areas of our business including SMARTY, B2B and Home Broadband. 

“The foundations of this are the enhancements to our network with 5G now covering more than a third of the UK’s population and rated as the fastest by Ookla, alongside a focus on improvements to customer experience.

“These enhancements are being supported by our highest ever levels of investment and are testament to the hard work of our staff and their efforts throughout a challenging 2021

“However, the UK market with 4 operators continues to remain dysfunctional and requires a structural change to improve the overall quality of infrastructure that UK customers should expect.”
