I've recently moved to Swish Fibre FTTP from Sky FTTC - they made an offer that no one could refuse, so far based on the experience I've had I'm incredibly impressed.

From the initial phone call right through to connection day, they have been very good, admittedly there was a delay in going live, but this was due to circumstances beyond their control and they did keep me up to date, so the sales team, aren't sign you up and forget, they really care and will keep you up to date.

Installation appointment team are fast and efficient, when the install team arrived to put fibre into the house, they discuss the entire install and make sure you are happy with everything, we had one small problem and the engineer wasn't going to leave until he saw the speeds I was promised.

EDIT: Well it's now been nearly 10 months and speeds and service have been solid, but the customer care I raved about has taken a complete nosedive, very long hold-times and someone answering the line "with hello, hello, then silence then hello" plus they're penalising customers on monthly contracts and not offering long term legacy customers better prices, yes the service is awesome but the customer care is beyond awful which I'd never thought I'd say about this business after my sign up experience. My concerns are as they get more popular - will they able to cope?
