Thanks for the info. I understand there are t&c's against running business on residential, so I'll make that clear to him.
I will recommend AA - and that's also someone I'm keen to look at myself in a year when my BT contract is up. I loved my time with BE, even though it was only standard ADSL2. Having a techy ISP and support who understand what you need and what you're asking for is priceless.
I bet AA will be one of the first ISP's to offer DLM changing on their control panel whenever that's released. I remember with BE, you could go onto your control panel and change anything.... latency type, line profile type. Being able to test your line out yourself, at your own leisure, was brill.
Am I right in thinking that the people behind Hyperoptic are former ‘BE’ folk? I’d be all over that myself if they did single residential dwellings…!
