For those interested, I spoke to BT this morning. Superfast broadband is now available on Golden Lane. There are two packages. Infinity 1 costs £18-00 pm plus a one off fee of £49-00 for a new router, with £7-95 added for delivery.
Infinity 2 costs £32-50 per month, with a free router but you pay for delivery of it at £7-95.
Had an email from BT with a link to a special offer to existing customers. My bill is now about £4.00 cheaper than it was and they have increased my speed to a guaranteed 50 mb/s.
I only renewed mine in March but I still got the offer, If you haven't had an email yet I am sure you will get it within the next few days.
