Sorry, it is a bit too far for me, I'm in north leeds.
You need to speak to your electrician, and speak to the DNO (or get your electrician to)
See if they will provide a main earth terminal (MET), failing that will need an earth rod installing, but this will require you to have and additional RCD installed onto your system.
I'm thinking a very short term fix would be to swap the RCD and main switch over. At least providing a bit of shock / fire protection.
Daytona, I think the OP means the cutout was replaced (reffered to as the main fuse box)
