Totally agree. Our ISP is Beaming (based in Hastings, but who cares?). When there's a problem with the infrastructure, we call them, speak to an engineer (no waiting, no call centre), and they do all the chasing and kicking of Openreach.
Costs more (£38 + VAT per month), but provides the level of service needed by a home-based business reliant on the internet.
Average download speeds mostly at 70+, but occasional periods as low as 45
Average uploads mostly around 17
But it's the service we get that has kept us with Beaming over 14 years and three locations.
