Is there anywhere in East Anglia that I can hire studio flash equipment, or do I have to go into London?

In January I will be needing some basic lighting gear near Eye in Suffolk. I know that I can rent truckloads of grip equipment from various places in London, but I was wondering if there are any local hire companies that I have missed in my googling.

What I need is one good light of about 500 Ws, preferably with a shoot-through umbrella softbox, plus stand. Maybe a second light and/or a more powerful light into a big softbox if logistics allow, but I prefer to keep things simple and compact.

All suggestions gratefully received.
