So the existing floor is unlikely to have any overboarding if the the floor heights are level.
Your taking a risk overtiling, not knowing what the makeup of the subfloor is. If you were to take this job on I would be explaining to the customer that no guarantee's would be offered and that entails for you if it did fail.

I have explained im not happy overtiling but i have done a lot of work in past for them and members of their family so dont really want give them a flat no, regarding substrate i assume as its a new build and was tiled when built it was prepared properly so the floor was level

I assume nothing, especially on new builds.

If you really must tile over (not in any way advised due to relying on previous prep) prime and grip primer, Mapei or TM will give you the best bond to existing tiles...

Got failure written all over it , it's not anything like tiling over a solid screed floor .

Sometimes you just have to take control - do it correctly or walk away - or you will find you don’t get any more work from them.
Nowhere have you said it’s a timber or solid floor.

Personally. I wouldn’t do it. What’s the floor. How were original tiles fixed?

go over the existing tiles in hardy backer board glue and screw no mess no problem

Screw though tiles Ray? ...self tappers

no put backer board over tiles mark out grout joints there you screw i asume tiles are on wood if not drill and plug

Take them up of don't do the job, it's a new build and weather it be timber or a screed floor, they will have been fixed badly.
