history of British public telephone boxes

Before 1876, communication over distance was often by telegraphy. The General Post Office/GPO, governmental till 1969, had the monopoly on UK’s telegraphic communication. The telephone was a marvellous technical innovation but very costly; use was limited to wealthy homeowners and businesses. And there wasn’t a single unified system; it was owned and operated by private companies operating local exchanges to which homes and businesses subscribed. In 1884 the GPO relaxed the rules that limited exchanges, meaning that the first public telephone network began with only 13,000 phones nationwide.

As technology improved, more services emerged. The GPO started with Jubilee Concession, installing a kiosk in all c8,000 towns with a Post Office. Acts of Parliament unified National Telephone Company/NTC and GPO services.

A UK telephone network division came pre-WW1 when NTC assets were acquired by the GPO, effectively nationalising the telephone network. With the combined staff and assets of two separate organisations, the GPO looked at equipment regulation, but WW1 put kiosk development on hold.

In 1921 Britain's standard kiosk K1 was introduced by Post Office. Its design was conservative so many of the phone box designs were protected by trademark registrations, held by British Telecommunications. K1, made of concrete, was not initially well-received. 14 K1 boxes remain, 7 registered by Historic England.

In 1923, two independent schemes were established to test design alternatives to K1. The Metropolitan Boroughs Standing Committee ran a competition to design a new national kiosk. And Birmingham Civic Society produced independent proposals for a new national kiosk, which they submitted to the GPO. This caused the newly established Parliamentary Royal Fine Art Commission (1924) to examine questions of public service and art value. The red telephone box emerged from a design competition.

 
K6

The public telephone box was designed by noted architect Sir Giles Gilbert Scott was in cast iron. Their distinctive red colour made them easily recognisable. From 1926, the kiosks displayed a prominent crown symbolising the government.

8 kiosk types were introduced by the GPO between 1926-83. The K6 was designed by Scott to mark the Silver Jubilee of King George V coronation in 1935. c60,000 examples were installed across Britain, explaining why the K6 became THE red Telephone Box. 11,000+ K6s remain. More stream-lined than the K2, the K6 was deployed widely by 1940, despite initial resistance to its red colour.

Scott’s design was like the K2, but smaller and cheaper to produce. The K6 was made of cast-iron sections, bolted together, standing on a concrete base. Its general design was a 4-sided rectangular box with a domed roof. The door was of teak, with a metal cup handle. Set into the slot was an illuminated telephone sign, with serif capital lettering on opaque glass. The pediments had a moulded Royal crown. 

Motoring organisations, Automobile Association/AA and Royal Automobile Club/RAC, enjoyed the benefits of a telephone network for members in a network of sentry boxes. Because cars were expensive and were prone to breakdowns, the motoring clubs employed patrolmen men to shelter in the boxes and to provide motorists with roadside aid. The Police Service also grew a network of kiosks, allowing officers to keep contact with their station. Metropolitan Police Service introduced Police boxes in 1929.

Scott’s winning design, chosen by the Royal Fine Art Commission, featured a classical style with a dome like John Soane’s. Scott was Director of the Sir John Soane Museum at the same time he was working on the telephone box design. The kiosk was ideally to be constructed from cast-iron with a per-unit price c£40. Three kiosks were installed behind London’s National Gallery in 1925.

Without a cost-effective kiosk used nationwide, GPO reverted to K1 with larger windows and revised signage. This was an interim solution, and by 1928 the GPO commissioned Scott to produce a cheaper kiosk made of pre-cast concrete. The GPO was not content with the K2 they had been working on, so they planned a new kiosk which could incorporate a stamp machine and post box; a mini-Post Office.

In 1929 Scott introduced K3, a similar design to the K2 but made from reinforced concrete for nation-wide use. The K3 was cheaper than the K2 but still more expensive than the K1. See a rare surviving K3 kiosk at the London Zoo.

The K4 was an enlarged version of K2, designed by GPO’s Engineering Dept. In 1927 the K4 model included a post box and stamp vending machines. But only 50 K4 kiosks were produced. The GPO planned for a low cost kiosk. Introduced in 1934, K5 was a metal-faced plywood work, designed to be portable and used at exhibitions, but never completed.

In 1937 the Tercentenary Concession celebrated GPO's 300th anniversary and 1,000 more kiosks were installed for local authorities paying low subscriptions. In 1939 a tougher version was introduced. In 1949 Royal Fine Arts Commission got re-involved, allowing rural examples in different colours. Post-war c60,000 examples lived, and of the 8 kiosk types introduced by the GPO, the K6 heritage legacy remains best.

Post-war, the 1951 Festival of Britain was held on London’s South Bank. The Festival was a tonic to Britain then, showing the recovery from austerity. It demonstrated skills in the arts, architecture, industrial design, science and technology. And a crown motif with Queen Elizabeth II.

Lending library in unused kiosk

In 1959 the GPO invited submissions for a new kiosk from leading architects. After considering 6 experimental designs, K7 kiosks were designed by Neville Conder and installed in 1962. Ahead of its time, the K7’s use of aluminium was only adopted much later. So the GPO opted for a design by Bruce Martin; he proposed aluminium, not the trusted cast-iron. K8 kiosk arrived July 1968. 1969 predicted the end of GPOs kiosks. Since its inception, the GPO was nationalised, but as a Government Dept. By 1981 the Post Office was split into two businesses, privatising telecommunications Ap 1984.

In a year British Telecom announced a £160 mill modernisation scheme: installing modern kiosks in the public network. But historical groups & progressive London boroughs highlighted the kiosks’ plight. Statutory protection was given to 2,000 key kiosks by English Heritage.

AA and RAC kiosks also worsened. Reliable vehicles allowed patrolmen to travel in their own vans and telephone equipment could be housed in smaller pedestals. And the Police kept in touch via personal radios. As British Telecom was left with unprofitable kiosks to maintain, the company created an Adopt a Kiosk Scheme, demonstrated the strength of local communities in preserving and maintaining their heritage. Local authorities adopted unused kiosks for £1, with the community accepting responsibility for maintenance. Organisations took these boxes for other uses eg some counties’ K6s became a community libraries after their mobile library services discontinued. Or a defibrillator.

The iconic design of the red telephone box found a place in parts of the world, eg U.S, Australia, New Zealand, where they have been preserved in historic sites. But the red telephone box is a beloved symbol of British heritage and their cultural significance endures. The red telephone box is an artwork, history and national identity, one of UK's favourite design icons in 2006!

  1. The red telephone box has always been a special symbol of England. It's a fun look and obviously has an interesting extensive history -which I knew nothing about- thanks for all the background information . I do love how the repurposed them now.

      I remember a red telephone kiosk opposite our Melbourne house in the 1950s, on the corner of two main roads. Although my parents had their own phone, clearly other families did not, so I loved watching the action. However until spouse and I moved to the UK in the early 1970s, I had no idea of the kiosk's special symbolic value to the UK

  2. Hello Hels, I second the above comment in thanking your for this history of the iconic telephone boxes. Except perhaps for the Eiffel Tower, I think these have been produced in miniature more often than any other structure. Taiwan still has phone booths, but I never see anyone in them anymore--cell phones I imagine made phone booths everywhere obsolete.

      it was inevitable that once families got their own lap tops and mobile phones, that public telephone boxes would not be added to the landscape any more. Existing kiosks would either be removed, left unused or converted into other uses.

  3. Very interesting, Hels, thank you. Our last local kiosk disappeared some years ago.

      I wonder if people would use a local kiosk these days. I have not, since 1970.

      Telstra Australia provides 14,000+ public payphones here which continue to provide valuable services to the community in an ever-changing digital world. Payphones have always been and continue to be a vital piece of social infrastructure, a beacon of safety and connection, especially for our most disadvantaged community.

  4. Bom dia Helen. Muito interessante essa matéria, sobre a cabine telefônica da Grã-Bretanha. Não conhecia essa história. Acho que a maioria das pessoas, nos dias atuais se comunicam pelo celular. Grande abraço do seu amigo brasileiro.

    that is true. With your own mobile phone, you can talk on the phone in bed, in a coffee shop or on a tram if you wanted.

  6. I never thought about the history of those classic phone booths. That was interesting. And I wonder if like here in the US, of these booths are still fairly common. I love how the idea of turning them into little libraries. Happy new month Hels.

      apparently William Gray invented the public payphone in the USA in 1889, and George A Long was its developer. With most people having mobile phones now, of course the number of kiosks has severely fallen and perhaps fewer than 100,000 are still found in the USA. Very few can still be seen.

      There were so many public telephone boxes when we were young, nobody thought much about their designers, owners and histories. Only once people largely stopped using them did we even think to examine their long history.

  8. That's a fascinating history. You've inspired me to write my own post about phone boxes.

      exactly. I only started reading and writing about phone boxes when I saw comments about them being used for other purposes eg lending libraries.

    2. I was reading this post and thinking I was sure it was about Australian phone boxes, I even scrolled to see if Hels wrote about Australian phones at some earlier time!
      I'm glad I'm not as crazy as I thought!

  9. The K2 that Giles Gilbert Scott designed is said to be inspired by the mausoleum that Sir John Soames designed for his late wife. The mausoleum can be seen in St Pancras churchyard near King's Cross. The red phone box can be seen all over the UK being used for a number of purposes from the mini book swaps to defibrillators and even a coffee shop.

      Many thanks! I had never seen the mausoleum in St Pancras churchyard near King's Cross yet I can see the inspiration of the Soames' design and Scott's K2. And I have never seen a coffee shop in a kiosk, but that would be fantastic.

  10. This richly detailed history shows how a piece of everyday infrastructure evolved into a national icon

      true that! There were squillions of everyday ordinary items in our world, but most disappear into nothing more than our grandmothers' vague memories. Only those few items that somehow evolved beyond their original purpose did they achieve an important status. And rich histories emerged.

  11. I love those old red phone boxes, it was a sad day when thugs begsn to vandalise them, and I'm happy now to see those that have been repurposed.

      I too am very glad to see a few of the old red phone boxes being repurposed in clever ways that we may not have ever thought of. My grandchildren suggested fitting out some unused phone boxes with large batteries, so they can recharge their phones and laptops when they cannot get home in time to plug in their equipment.

      But vandals who take pleasure in destroying public property make me angrier than people who steal food to feed their hungry children.

    I have been working on the role of Heritage Protection on historically important buildings and services. It breaks my heart when at least some historical treasures are not protected for ever.
    So if there were tens of thousands of red boxes, not too many need to be preserved. Or one museum, perhaps.

  14. Phone boxes, police boxes and motor assist boxes must have made for a lot of roadside shelters.
    I like the idea of a post box and stamp vending machine. I would use one of those.

      nothing stays the same, does it? Not only do 97% of Australians use mobile phones these days, but under 3% of letters sent in Australia are by individuals using envelopes and stamps.
