What do Wheatley Road in Corringham, Essex, and Erw Fawr in Henryd, North Wales, have in common? The answer: the UK's slowest average broadband speeds.
Research from uSwitch - which carried out almost two million speed tests - has shed light on the UK's greatest 'not-spots'.
These are the areas yet to benefit in any sort of way from the nationwide rollout of next-generation broadband services.
Residents living on Wheatley Road and Erw Fawr are able to download data at a rate of just 0.60Mb: around 30 times slower than the UK average speed of 17.8Mb.
Despite its relatively close proximity to London, Essex has a number of the UK's slowest broadband addresses.
Its roads feature six times in uSwitch's list of the UK’s 50 slowest streets - more than any other county.
Princes Avenue in Maylandsea, Chelmsford, is the slowest Essex street after Wheatley Road, with residents contending with average speeds of just 1.15Mb.
uSwitch found that just 15 per cent of Brits are benefiting from broadband speeds of 30Mb or higher - the speed classified by the European Union as super-fast.
This is despite super-fast broadband being available to 73 per cent of the UK population, according to Ofcom research.
At the other end of the scale, people living in Unstone, Derbyshire, are enjoying the fastest download speeds in the country - an average of 57.58Mb.
The study revealed that residents are receiving average speeds 96 times faster than Erw Fawr and Wheatley Road.
Marie-Louise Abretti, broadband expert at uSwitch.com, said there are still areas in the UK that experience broadband speeds "so slow the service is negligible".
"At the same time, super-fast broadband connections are becoming more widely available but - as our research suggests - these are clearly not being utilised," she stated.
Ms Abretti claimed that more needs to be done to increase awareness of broadband availability and cost.
"Super-fast broadband isn’t as expensive as some users might think, with prices starting at £16 per month plus £15 for line rental," she explained.
"Paying line rental upfront can result in savings of around £50 per year and many of the providers have introductory offers. So, for households in the slow lane, super-fast broadband could be well worth considering."
