You will have to check with the garage that gave you the quote, but usalle the brake fluid change is usally and extra £45.
Just to give you an idea of price to pay look at this link: http://www.focusstoc.com/forums/Service-Packages-t50210.html
But the 2nd year price here does include plugs and brake fluid change.
If you can get your 2nd service for £195 with the brake fluid change I would bite their hand off.
If you are going to a Ford dealer then shop around for the best quote and also see if there is anyone in your local region that has experience of the local dealers and whether they'd recommend them or not. You may find that some dealers will price match a cheaper one to get the trade.
As has already been said, see if you can get the brake fluid changed as part of the deal.
