London is officially the UK’s best digitally connected city. A global hub for international business and finance, the capital scored top in our digital connection index that weighs up factors such as internet speed, fibre optic broadband coverage, and mobile data availability. Bristol came second on our list, and Cardiff took third.
Notably, the cities of Coventry, Nottingham, Birmingham, and Leicester all represent the Midlands in the UK’s top 10 most connected cities while, heading further north, only Liverpool and Glasgow rank among the 10 best cities for remaining connected.
Despite London topping the list, northern cities take the lead when it comes to finding a great 4G connection. Bristol is the only southern city outside of the capital to offer connectivity at more than 90% of premises, whereas Edinburgh, Glasgow, Newcastle, Manchester and Liverpool all represent the north in offering 4G coverage at 90% or more homes.
Being one of the UK’s top digital hubs, Leeds follows this regional trend but does struggle when it comes to a good overall connection, especially when compared to other northern cities like Newcastle, Nottingham and Liverpool.
In order to find the speediest connections in the UK, we’ve compiled the mean download speed and mean upload speed for the 20 most populated areas in the UK to give an overall speed score.

Surprisingly London isn’t the best place for a quick connection. In fact, Cardiff has the fastest internet, with Nottingham, Bristol, Wigan and Edinburgh the only other cities with a speed score of nine out of 10 or more.
Manchester has the lowest speed score in the North West, behind Wigan and Liverpool, while Leeds has the quickest internet connection in Yorkshire. Nottingham, Dudley, Leicester, and Birmingham all occupy a spot in the top 10 cities for internet speed, suggesting the Midlands is a hotspot for quick internet.

Within London, Southwark in the centre is the best connected borough, with Bromley in south London proving to be the least connected.
Interestingly, Lambeth lies immediately west of Southwark but sits in the bottom third of London boroughs for digital connectivity.
The boroughs of Southwark, Westminster and the City of London are all among the main financial districts in the city, however, while Southwark is the capital’s best connected borough, the City of London and Westminster are among the worst, overall.
The two underperforming locales, though, are both in the top five areas of London for a full fibre connection, joined by Tower Hamlets, Hammersmith and Fulham, and Southwark. The latter offers a full connection at almost 50% of premises, better than anywhere else in the UK.
For the best 4G connection in London head to the centre of the city, with each of the central boroughs all offering 99% coverage, or better. Hammersmith and Fulham is the only borough outside the centre to offer full 4G coverage, with the City of London, Kensington and Chelsea, Islington, and Westminster all offering 100% coverage, too.

For the quickest internet in London head over to Richmond upon Thames, which has an impressive connection speed score of 9.9. Notably, however, the business districts of Southwark, Tower Hamlets, Westminster and City of London all register the worst internet speeds across the entire capital, each with an index score of below seven. Similarly, the boroughs of Westminster and the City of London all offer 100% 4G coverage but rank as the two poorest areas in the country for internet speed.
To create our index of the UK’s Most Connected Cities, we combined data based on internet speed, fibre optic broadband coverage and mobile data availability around the UK.
We gathered these statistics from the Connected Nations 2018 report.
