They unfortunately have datacaps and don't offer fiber only openreach FTTC style connections at best and at about 3 times what I pay for 1gbit up/down in London ATM.
London and some other parts of the UK have FTTH now, and it's cheap I am paying 30GBP for a 1 gig symetric connection via hyperoptic.
Fiber to the curb is not fiber, anything below 300MBit should not even be considered broadband at this day and age tbh.
