Mapped: The best and worst places in the country for broadband
Broadband speeds vary significantly across the UK, with download rates in different constituencies varying by up to eight times.
Average download speeds measure by constituency vary from 5.6 Megabits per second in Na h-Eileanan an Iar (the outer Hebrides), to, surprisingly, 46.8 Mbps in Great Grimsby.
Using the map below, you can see how broadband in your area of England, Wales or Scotland, measured by average download speed, measures up to the national average of 29.4 Mbps.
The figures come from Ofcom's Connected Nations 2015 report, and have been split into constituency by a House of Commons Library briefing into the UK's broadband infrastructure.
A recent report signed by dozens of MPs said that the UK's broadband industry needs to be radically shaken up by forcing BT to be separated from Openreach, its arms-length network division.
Even some of the most highly-populated areas of the country lack good broadband, according to the report. The Cities of London and Westminster constituency has an average speed of 16.9 Mbps and 78 per cent superfast access.
Ofcom's figures represent the download speed users are receiving, rather than available speeds, so figures can be influenced by what speeds households are paying for.
Under a 10Mbps connection, a two-hour standard definition film would take about 20 minutes to download.
Over 400,000 small and medium businesses do not have access to superfast broadband in the UK, as do some 16 per cent of households.
Recently, a survey by the Engineering Employers Foundation found that nearly half of companies in business parks were unable to access speeds above 10 Mbps.
