I recently finished a job started 18 months ago to fit an electric shower.
The wiring was done by my now ill father-in-law, and I merely attached the
shower, fitted an earth leakage circuit breaker, and an isolating switch.

When I first tested it, everything seemed fine- I was then though told to
fit this earth leakage circuit breaker- as soon the shower is now turned on,
this trips off.

Any ideas as to what I nee to do?

You didn't provide anywhere near enough detail of the setup.
However, you really need to get this installation checked out
by a proper electrician, who will also do the fault-finding
for you.

Water and electricity - a quick way to the exit door.

If the circuit only trips when the shower is operating then it isn't likely 
to be a wirng fault. More likely a problem in the shower itself. Fit a new 
one.

Stating the obvious here. You must have a path from either the neutral or
live feed down to the earth.
In order of cost to fix/diagnose
Look for trapped or abrased wiring first. No rubber grommets on metal boxes
is a favourite. Look for poor ternimation into junctions as well.

Is the RCD a combined MCB/RCD is this correctly rated for the shower
installed (is this an over current fault rather than an earth leakage).

Have a look and see if inside the fuse box that this is ternimated
correctly.

Replace the RCD as sometimes (rarely) these can be dodgy.

But I guess as the guy before says. It looks like a shower unit fault
itself.
