UK prices can be expensive. I've got mine with British Telecom (BT) on their Infinity 2 fibre connection. The other issue is that with Fibre (FTTC) you also are required to take out your line rental and phone call plans with the same company as the Internet connection.
Line rental is normally about £16.99 a month, plus £26 for fibre.. So that is £42.99. Then you have addons for phone calls, such as all inclusive calls for £7 per month. So it quickly adds up.
