"Huawei remains an important equipment provider outside the core network, and a valued innovation partner", BT said in a statement.
Things aren't looking any better for the 5G future either, as BT says it will not include the Chinese company in the bidding for contracts to supply equipment for the next generation in mobile connectivity.
Earlier this year, Australia too banned Huawei from supplying 5G equipment, also citing security risks.
Huawei - one of the world's largest mobile equipment and service providers - has always been under scrutiny over its allegedly close ties to China's state intelligence services.
"In 2016, following the acquisition of EE, we began a process to remove Huawei equipment from the core of our 3G and 4G networks, as part of network architecture principles in place since 2006", a BT spokesperson said.
TELCO GIANT BT will remove Huawei equipment from its core 4G network within two years, according to the Financial Times.
"We're applying these same principles to our current RFP (request for proposal) for 5G core infrastructure", BT said.More news: Khashoggi murder: Turkey orders arrest of senior Saudi officials

BT is removing kit made by Chinese firm Huawei from its network amid fears of spying. Despite Huawei being a major provider of network equipment, BT has stated that it will not be utilising the technology at the "core" of its service.
It added that Huawei would still be part of its secondary "5G Radio Access Network".
"Working together, we have already completed a number of successful 5G trials across different sites in London, and we will continue to work with BT in the 5G era", a company spokesperson wrote in an emailed statement.
Such concerns are front of mind for many just two days after Alex Younger, head of the UK's foreign intelligence agency, MI6, told a crowd of students at St Andrews: "We need to decide the extent to which we are going to be comfortable with Chinese ownership of these technologies and these platforms in an environment where some of our allies have taken quite a definite position".
BT's announcement follows United Kingdom foreign intelligence services chief saying earlier this week that using Chinese technology for 5G was something the nation needed to discuss.
What do you think about U.S. allies dropping Huawei?
The report said the Chinese government could force companies to make products perform below expectations, facilitate "state or corporate espionage" or compromise the confidentiality of networks using them.
