You can check ford etis as its a website just type ford etis UK in Google. Then you just enter the vehicle reg or chassis number and it brings up everything about that car. All garages will try to up sell as that's how the service advisers make there bonus. Check etis on what should be done and take a print out with you as they shouldn't charge extra for work that's done in the service costs.
cheers, i thought it was a log in site, just saved the 3 year & 4 year service schedules, i'm away offshore tomorrow so i'll email my brother, who's better at questioning the service guys then me lol
