The first 5,000 homes and businesses can now connect to Openreach’s full fibre network in Perth, through the Scottish Government’s Reaching 100% programme.
Grain has earmarked the 11 locations that will make up the next phase of its national full fibre rollout.
Next in line for Grain's network expansion plans are Birmingham, Bolton, Bradford, Burnley, Manchester, Middlesbrough, Newcastle, North Shields, Oldham, Plymouth and Swindon.
Tracy Karam, Head of CX, said: "The response from residents and businesses to what we are offering has been very positive, with many signing up to our service before work on their street has even been started."
This will take the total towns and cities connected by Grain to 26.
