Ringing in the changes for the great British phone box: From the iconic red kiosks to the many redesigns that followed, how the payphone became part of our national identity as BT plans on giving them a 21st century makeover after years of decline

  • The first standardised phone box - the K1 - was introduced in 1921 

For decades, they were the place where nascent lovers enjoyed as long a conversation as their supply of coins would allow.

Late at night on a quiet street corner, the phone box was the friend of the misty-eyed, the desperate, and anyone who wanted to call home with good news. 

But with the advent of the mobile phone, the most quintessential of British objects has become something of an eccentricity. 

Many of those that do remain, such as the classic K2 model that stands near Parliament, act as photo opportunities for thousands of Britons and tourists every year. 

Now, operator BT is to transform 2,000 old payphones into digital hubs that will provide free calls and wifi, as well as device charging.

The move marks yet another attempt to revive the traditional phone box. Although many are now neglected and derelict, some have inventively been turned into miniature cafes and libraries. 

And around 3,000 have been designated as grade II-listed buildings, meaning they are saved for the future.

Although the first standardised phone box - the K1 - was introduced in 1921, the most transformative design came in 1936. The K6 was a tribute to King George V's Silver Jubilee that year. 

The designer of the K6, Sir Giles Gilbert Scott, had initially designed the K2 - which was introduced in 1926 - and was inspired by a 200-year-old memorial at St Pancras Old Church. 

The Soane Memorial was raised over the grave of architect Sir John Soane's wife Eliza in the churchyard in 1816, and became the family vault - giving Sir Giles Gilbert Scott the idea for the K2 in a competition in 1924. 

Sir John was a renowned neo-classical architect behind the Bank of England, churches, and country houses, while Mr Scott was well acquainted with the tomb having been a trustee of Sir John Soane's Museum for 35 years. 

However, after Mr Scott won the Royal Fine Arts Commission prize, the Post Office insisted on the K2 being made from cast iron and painted red - despite his hopes it would be built from mild steel and coloured silver.

The postmaster general was the first person to offer members of the public a telephone service in return for a small charge when he allowed telephone companies to install 'public call offices'.

The earliest examples were found in Manchester, Liverpool, Blackburn and Preston, where a three minute call cost three pence. 

These wooden structures paved the way for the Post Office to introduce the standardised K1. 

Finished in white and red, it made the telephone available to millions of people for the first time.

The K2 was entirely red, sparking off a design theme that would last for decades.

Three more 'K' kiosks were conceived over the next ten years before the K6 was introduced.

Known as the 'jubilee kiosk', it was the first to be deployed extensively outside London, with thousands being erected in towns and cities across the country. 

Within four years of its introduction the number of public UK red telephones rocketed from 19,000 to 35,000, paving the way for it to become an internationally recognised design.

By the time production of the K6 came to an end in 1968, there were some 70,000 on streets around the country. 

It was a triumph for Sir Giles, who was also responsible for designing Liverpool's Anglican Cathedral, Battersea Power Station and Bankside Power Station, now home to contemporary art gallery Tate Modern.

The phone box's status as a national icon was further boosted with the help of iconic TV show Dr Who. 

The Doctor's Tardis was - and remains - a police call box. It is small on the outside and unfathomably big on the inside. 

Phone boxes have also had roles in films such as 2001: A Space Odyssey, Die Hard and Dirty Harry - as well as Colin Farrell's Phone Booth in 2002. 

When BT separated from the Post Office in the early 1980s the classic kiosk design was replaced with the unsightly KX series of glass phoneboxes.

BT expanded the number of public call boxes from 70,000 in 1984 to around 132,000 ten years later.

However, the more modern designs were particular targets for vandals. Many had their wires pulled out or ended up covered in graffiti.

Some were roofless and had only one side, meaning they provided no shelter from the British weather.

BT began removing hundreds of phone boxes in a scheme started in 2008. Some refurbished boxes have been sold on to the general public and private companies. 

Now, there are just over 20,000 working phone boxes left. Ofcom previously vowed to protect 5,000 from closure in areas where there are high accident rates or poor mobile coverage. 

Ofcom said in 2022 that five million calls are still made from phone boxes annually.
