After 31 December, UK telecom operators are being barred from purchasing new Huawei 5G devices, and by 2027, they will also delete the Chinese firm’s 5G kit from their networks.
Public Secretary Oliver Dowden conveyed the announcement to the House of Commons.
It follows sanctions imposed by Washington, saying the company poses a national security threat -something Huawei denies.
Mr. Dowden said the supply ban would delay the UK’s 5G rollout by a year.
The system offers faster Internet speeds and the potential to accommodate more connected apps, which will be a boon to anything from mobile gaming to higher-quality video streams, and driverless cars that speak to each other even in time. 5 G connections in dozens of UK cities and towns are already available but coverage may be limited.
Mr. Dowden added that the combined cost of changes in accordance with earlier restrictions on Huawei would be up to £2bn, with a total delay of ‘two to three years’ to 5G launch.
“This has not been an easy decision, but it is the right one for the UK telecoms networks, for our national security and our economy, both now and indeed in the long run.”
Since the US sanctions only affect future devices, the government has been told that there is no security reason for withdrawing Huawei supplied 2 G, 3 G, and 4 G devices.
However, networks are likely to turn to another provider to offer the facilities of the earlier-generation while switching out the company’s masts.
According to Huawei, “the move was bad news for anyone in the UK with a mobile phone” and threatened to “move Britain into the digital slow lane, push up bills and deepen the digital divide.”
