Yep, as long as the work is done with genuine parts using a VAT registered garage you are in the clear with warranties. I would however probably get the biggy services, or at least the last one before the warranty runs out done by a VW dealer just so they can change any parts that are dodgy before you've got to cough up for them yourself (see, I could be Scottish too).
Another recommendation I would throw in would be to have the car serviced annually rather than the time and distance regime but using the higher grade T&D oil. This would ensure the engine is kept in the best possible internal condition if you are keeping the car beyond the warranty period. Obviously for those hiring their cars though PCP or whatever that is pretty irrelevant!
