I was with Aquiss on an FTTC service in 2016 (I can still see the old tickets from back then in their support portal) and apart from some issues with the connection they were great. Martin was always spot on with the support.
So when the time came to move ISP's who did I consider 1st.. Aquiss.
I did look at other providers but over all the offer at time was the best one.
CJT.
Currently on Aquiss FTTP 550/70
