There is nobody quite like Andrews & Arnold. A proper, technical ISP for technically-minded customers. Of course, they would do a fine job for anyone else too! But their special range of services, approachability, and technical competence are a real breath of fresh air. No more call centres, no more fob-offs, no more marketing nonsense, and no gimmicks. Just a solid, traditional connectivity service, run by experts, which does what you need it to, month after month.

Update: I've now been with them for 5 years without a blip. Yes, you pay more, but you get an offering that almost nobody else provides. I recently switched from VDSL to FTTP (at last!) and the transition was seamless, with barely 30 mins of downtime during the physical installation by Openreach.
