If you're in an FTTC enabled area you'll be able to order fibre to the premise (FTTP) from the 29th April. You have to pay for the dig in the form of a fixed £500 fee plus a distance based construction charge. Then there'll be a £38 per month charge (all charges are plus VAT) that the ISP will then be looking to put their markup onto.
What does this mean? FTTC tops out at 80Mb down and 20Mb up if you live on top of the cabinet. FTTP will give you 330Mb down and 30Mb up and completely removes the copper segment and therefore the distance from the cabinet variable of FTTC.
