The ISP tweeted a link to a postcode checker this week, reminding customers that their free upgrade is on its way and inviting them to check to find out when it will be available in their area.

The earliest upgrades start rolling out during February and will see top-tier 120MB customers getting uplifted to 152MB. Customers on lower tiers should see their speeds increase by 20MB.

“We’re committed to making sure your broadband stays one step ahead of whatever you need it for,” the company said in a statement.
