I'm on original disks and pads at 42k but I guess it depends a bit on your usual journeys and driving style. I don't brake ever. Well ok not often. 85 miles per day commuting with about 95% sitting on a quiet motorway at 70 mph.
They're having you on aren't they !!!!
New discs at the same time as first set of pads, Robs right bud, they're bending you over royally !!!
Did they give you a reason why they needed replacing?
Have they gone below minimum thickness?
Are they scored?
Are they cracked beyond repair?
Or are they desperate for as much profit as possible out of you?
They tried it on with me when I first came over (I used to live in the US) on my first UK Lexus - luckily I had one in the US and went through 2-3 sets of pads for every discs so I know they can. The guy was genuinely telling me I needed new discs and I couldn't believe it. I asked him if discs in the UK were different from the US ones - he couldn't answer lol
If this is your first set of pads, then skimming the discs will solve most problems - there is not many problems which warrant new discs at 42k!!
Check out www.skimmydiscs.co.uk if you're interested. Incidentally skimming discs when getting new pads fitted will negate the bedding period and give you 100% braking performance as soon as you leave the workshop rather than having dodgy brakes for 500 odd miles.
You shouldn't need new discs and I doubt you need a skim either !!!
Good luck
