More than a quarter of UK broadband users have connection speeds slower than three Mbps.
This is according to a new study by price comparison and switching website uSwitch.com, which found there is not a single major city or town in the country that can yet be considered super-fast.
By testing the average broadband speed in the UK's 50 largest settlements, the company found only three - Telford, Belfast and Portsmouth - have typical connections of 20 Mbps or more. Meanwhile, 27 per cent of internet users in the country as a whole are having to cope with speeds of less than three Mbps.
Even in London, the average service cannot be classed as super-fast as it only reaches 17 Mbps and 19 per cent of households are struggling with very low speeds.
Telecoms expert at uSwitch.com Marie-Louise Abretti commented: "Urban speeds in the UK are around three times faster than rural speeds, but even download speeds in Britain’s 50 biggest cities still aren't super-fast."
Of the country's largest towns and cities, the average broadband speed is slowest in Hull, where it reaches just 10.5 Mbps. York, Norwich, Blackpool and Aberdeen also suffer from some of the poorest connections.
Huddersfield, Norwich and York all have more than a third of households using speeds of less than three Mbps, while the figure stands at 31 per cent in Milton Keynes. According to uSwitch, it would take roughly six hours to download a BluRay film with such a slow connection.
People living in these areas could benefit from switching to satellite broadband, which can provide speeds of up to 20 Mbps regardless of location.
This technology does not operate on the same network as internet service providers such as BT, meaning there is less chance of it being slowed down by other users. It is available now and can be installed and fully functioning within a few weeks of placing an order.
