The KX100 design caused controversy when it replaced the classic red phone box – but now a handful may be given listed status

Campaigners are trying to secure listed status for the “boringly ugly” telephone boxes that BT controversially used to replace thousands of red phone boxes in the 1980s.

The Twentieth Century Society, which champions outstanding examples of modern design, has applied for listed status for one KX100 box each in England, Scotland and Wales before they are removed next year.

In England, the 100,000th box to be installed in the country, located at Dunsop Bridge in Lancashire, which sits at the geographic centre of Great Britain and its 401 associated islands.

In Scotland, a contender for the country’s most remote and scenic payphone near Maaruig, on the Isle of Harris. It is believed to be the only example still bearing the full original yellow British Telecom livery.

In Wales, an experimental model at the Centre for Alternative Technology in Machynlleth, which is uniquely powered by a solar panel atop the kiosk and an adjacent 18ft-high wind turbine.
