Servicing away from the dealer - bad idea?

I have a 2006 Mondeo diesel with 112,000 miles. It's always been main dealer serviced. What difference to the value of the car would it make if a one-man operation services it but uses all the correct parts and follows the Ford schedule? I may change the car in 12-18 months.
Not that much now because its value is already marginal at about £1,600.
