We've got a pair of these, Kikatek.com | (SU3000RMINET) APC Smart-UPS 3000VA Line Interactive Rackmount 5U plus a smaller one for the phone system - all on 16A plugs.
Just got a 10kva w/10mins uptime UPS (Rotation+ 6kVA - 10kVA Parallel | Borri) from Borri UK. Total cost was about £2,400 but do bare in mind that it needs a dedicated hardwired 50A input feed, and has to have a hardwired output (so you'll need a PDU as well!).
We've just got an APC 3000. Plugs into a normal socket. At the moment we've got two storage arrays, 4 servers and a tape changer on it. I'm probably gonna thin it out a bit since we've got a few 1500s knocking about.
