Possible asbestos in artex wall

P933alilli

I have an old bungalow which has artex in a wall in the kitchen which ive been told may have asbestos fibres within it. Problem is ive recently had a rewire so part of the chasing was done in that wall before the cables were run through and then finally re-plastered. So, the asbestos, if its there, will have been disturbed temporarily and the fibres become airbound. I swept the area and vacuumed it after the re-plaster job.

  Now i need it painting and decorating and i'm just thinking of having the wall painted all over. To compound matters i may have a new kitchen which would involve pulling up the old floor tiles from the 1960's. I dont think the tiles are artex but i'm not 100% positive and neither do i know what is underneath them.

    Ive been quoted £225+ vat to take samples from the wall and tiles and wondered if this was reasonable? Obviously it should have been tested for asbestos before the rewire. Do, i need to worry about it now that any exposure, however brief, will have been done? Can a new floor be laid on top of the existing tiles?
