Cranbrook in Kent is the slowest area in the UK for internet broadband, according to research from uSwitch.
The speed is five times slower than the national average and more than 14 times slower than Leamington Spa – the UK's fastest town.
The average speed in Cranbrook is 1.32Mb - this means it would take 45 minutes to download a music album and 12 hours for a film.
Next worst on the list is Tregaron in Ceredigion in Wales with a speed of 1.48Mb – four and a half times slower than the national average. Third bottom is Lavant in Sussex with an average speed of 1.65Mb.
King's Lynn in Norwich, Basingstoke in Hampshire and Lowestoft in Suffolk also featured in the list of the bottom 10 areas.
On the other end of the scale Leamington Spa in Warwickshire has the fastest broadband speed of 18.86Mb with Welling in Greater London second with a speed of 18.42Mb and Herne Hill in London third with a speed of 17.89Mb.
This compares to an average speed in the UK of 6.8Mb, according to Ofcom.
Kent and Sussex were the country's two worst counties and geographically the North fared much better with over half of the top 20 worst areas in the South of England.
The research is based on data from 400,000 tests conducted between May and July this year.
Ernest Doku, spokesperson at uSwitch.com, says the research is black and white evidence that thousands of homes are making do with download speeds well below the national average.
"Fast broadband speeds should be available to everyone, not just for those people living in heavily urbanised areas. These latest figures highlight that, despite considerable investment, many areas of the UK are still living in the broadband dark ages.
"Intense competition among broadband providers means that companies such as BT and Virgin Media are rolling out super-fast fibre optic networks as a priority.
"We hope that this will convert into faster broadband for people in every area of the UK, whether urban or rural — and however low the population," he adds.
The Moneywise broadband campaign
Last year Moneywise began its faster and better broadband campaign to call on providers, Ofcom and the government to stop dragging their feet and start making improvements to broadband speeds.
Providers are promising super-fast next-generation services to urban areas but today's research shows they're still ignoring the fact that high speed broadband is still a requirement for rural Britain.
