I take it the car isnt on 10,000 miles? Its just on a short life service cycle? so every 10,000 miles?
You should expect:-
Oil & oil filter change
Pollen Filter Change
A good visual inspection of the car - Tyres, brakes, suspention,
Service light reset (of corse)
Book stamped
You could also ask for fuel filter change at added cost.
All of the above should sit around £125 - £175. With main dealer slightly above the top end price with less replacement parts ( as usual )
