Hmm , I thought I had notification set on, but obviously not!
Our income is way too low to register for VAT, we will probably just hit around £5-6k this year (we're a VERY small charity)
The line and BB aren't essential to the charity, it's purely for some small youth group use, a little training etc, so there wouldn't be loss case or problems with no SLA. Our usage is very low too (less than 1GB a month currently)
We have tried using 3G, but the signal is terrible, and often drops to GPRS, so we do need a fixed line, but we also need the cheapest possible.
