Revealed: The UK cities with the fastest and slowest broadband speeds – so how does your region fare?

  • Broadband Genie analyzed 265,572 consumer speed tests from across the UK
  • Canterbury has the worst average speeds, while Belfast has the best connection

We’ve all been there: you download a movie or stream a song and then you’re greeted by the “spinning wheel of death.”

Slow broadband speeds are something many Brits are struggling with, and new figures now reveal which cities have the worst connections.

Consumer speed tests from Broadband Genie show Canterbury is the city with the slowest average speed, closely followed by Ripon and Chester.

In contrast, people in Belfast, Portsmouth and Milton Keynes enjoy the highest average speeds, the report says.

“No broadband customer should accept subpar service, especially in a year where we have seen record price increases in the industry,” said Alex Tofts, broadband expert at Broadband Genie.

Scroll down for average speeds for all UK cities.

Meanwhile, the village of Halkirk in Caithness has been named the slowest area in any part of the UK, with residents achieving an average speed of just 2.8MB.

For reference, Ofcom advises that 10MB is the minimum “decent” speed that households should receive.

In contrast, Lochwinnoch in Renfrewshire has the fastest broadband speeds in the UK, with an impressive average of 409MB per household.

“Most of the UK’s largest providers sign up to the Ofcom Code of Practice on broadband speeds,” Tufts said.

“This means they need to be clear about what speeds you can expect at your address, including a guaranteed minimum speed that they must adhere to.”

“Speed ​​testing is a useful tool for regularly monitoring the performance you are receiving.” If promised services are not being delivered, contact your provider and raise the issue.

“Keep in mind that poor broadband speeds can also be affected by factors beyond your provider’s control. So be sure to check these first.”

“Poor wiring at home or a poorly positioned or broken router could be affecting your Wi-Fi.”

“Residents in the slowest cities could also suffer needlessly because faster speeds are available in their area if they change.”

“If you’re out of contract and want to upgrade your broadband connection, do a quick online comparison to see the best deals.”

“You might even end up paying less for better, faster service.”
