Is it just the rear axle pinion seal part that will be needed or are there any other parts?
Finally, is it a big job for a garage to do in terms of cost or hours - any ideas what bill I will be looking at?

If it just recently started leaking there shouldn't be any damage.
To repair involves:
*Mark rear universal joint yoke and pinion flange to reinstall in same position to maintain balance.
Remove the four bolts holding rear universal joint yoke onto pinion flange;
Check for excess play between flange and axle housing, either up & down or in & out to check for signs of pinion bearing wear. Excess wear must be addressed.
Remove large nut and pinion flange;
Remove pinion seal.
Install pinion flange and nut and tighten to correct torque;
Install universal joint yoke onto flange observing balance marks made before removal;
Tighten four yoke-to-pinion flange bolts.
Pull plug on differential cover and check fluid level. It should be at the bottom of the hole with plug removed.
I don't know what a garage would charge to do this, specially in the UK.
