Thanks for that mate and will pass on your info to the engineer who is coming round tomorrow.Dont want to turn anything on just incase the electrics have got water in them.Will hopefully post with a positive outcome which i can share.
You need to read this thread and it says exactly what you need to do to check where its leaking from!
Start saving up as it would be an expensive repair. Or call Baxi for a fixed price repair as that may be cheaper!

Read the FAQ on this site where it should show how to decide if a leak is in the system or boiler!
left to right
HTG 22mm
DHW out 15mm
Gas 22mm
CW inlet 15mm
HTG 22mm
valves are chrome and either have plastic isolators or square chrome isolators
Isolate both heating valves with the boiler at 1.5 bar. If it still goes down leak is on boiler
pressurise boiler to 1.5bar, turn it off (power) then far left and far right black isolators quarter turn to isolate the heating circuit.
If the pressure doesn't drop over the usual period the leak is on the heating system. If it does it's the boiler.
