I'd start by looking at the service guide and the history of services to date.

Then you need to ask both exactly what jobs over and above oil and filter they're quoting for. Quite possible that there's a difference of interpretation over time and mileage related items or that the more expensive quote is picking up optional or advisory items like brake fluid or coolant changes.

has the car been serviced before ?

how many miles have you done ?

what does it tell you in the service book ?

Hi - OP here...

The car is 3.5 years old and has done 40k miles - this is a service milestone. I did find an online service book but it was very confusing - it listed all sorts of models and engine sizes and i cant make head nor tail of it. Just wondered if other 207 owners had heard of this A, B & C type service schedule or if its a full major service and any idea of price.

The local garage says he does oil, air filter, brake fluid, pollen filter, spark plugs and 2.5 hours labour.

I will ring tomorrow and ask what the Main dealer includes.

Oil, air, fuel and pollen filters plus oil change - £192 at my local indy garage. That was for a diesel, may be different for a petrol. It's an 08 model by the way.
