If I have my FIAT Grande Punto serviced at a non-franchised dealer, will it invalidate the warranty?

I own a FIAT Grande Punto 57-reg, and have just been quoted £440 for a 36,000 mile service from my local FIAT dealer in Slough. This seems a bit excessive to me. Should I opt to get the service done elsewhere away from the main dealer network or will this void the car's manufacturer's warranty? Can you recommend any other FIAT specialists that may be able to offer this service cheaper?
