1. Yes, you can tile over if the vinyl isn't loose and it's not too greasy, otherwise you'll have to clean it properly

2. Only wood you can tile onto is plywood

3. You either know asbest or you don't. Sorry, can't help you with that.

Yes you can if the vinyl is stuck well, but not recommended.

I would never tile onto chip, always overboard.

Asbestos, now there's a problem, the naked eye can NOT tell the difference, if it's a site, old or new, they should have an asbestos register that identifies what and where any know dangers are, why do you ask ?

3. You either know asbest or you don't. Sorry, can't help you with that.

And how do 'you' know ?

Depends which adhesive manufacturer you deal with. Ardex state you can tile straight onto flooring grade chipboard with their 7001 addy (primed with P51 first) as long as the floor is solid.

Personally I prefer to over board, but as an abso necessity if overboarding is not practical/possible then you could go along with Ardex advice I suppose.

If you suspect Asbestos then a value for money way of finding out is via a self testing kit which will cost your client £99 including VAT.

Can I suggest that if you suspect Asbestos then your client should be funding the investigation and that it is not part of your quotation.

If you have a subcontractor come and test it then at least you have a benchmark price for the cost of the work. If its more than £99 then your client is paying too much.

Then all you have to do is weigh up the cost of the local service and compare it to an online fixed price service.

If it were me and a local service were doing the work for say £130 then I'd pay the extra to save all the hassle of having to take the samples yourself and dispose of the clothing and kit supplied.

For more details on the £99 self testing kits then this is a link to a site (other sites are avaialble)

I am a DIY tiler at best - I have tiled on chip board twice. Once on a floor and once on a wall. Floor with bagged addy and the wall with tubbed addy. Both walls primed and well fixed. Both walls failed and had to replace. Replaced the floor with Plywood and the wall with plasterboard and both have now survived for 10 years or so. That said you can apparently tile on chip board but I would not do it again myself.

The vynil tiles will depend entirley on what type they are and how old they are and how well stuck down they are.

asbestos .... yuk - been there done that - my house was partly converted to flats when I bought it and I converted it back again. The top floor flat (attic conversion) was lined with asbestos as a fire break. Was horrible stuff to deal with but that was before the times when you couldn't hide it at the bottom of the skip so all I have to worry about is asbestosis in a few years time I suppose. I know it was asbestos cos I know what sheets of it look like but how you tell if it is in your floor tiles I have no idea. sorry

Don't bother messing with asbestos if you think there's even a 1% chance it could be. Asbestosis kills you after a long long time and can seriously damage your lungs, and then some. I had a close friend who caught asbestosis and ended up with severe fatal lung cancer, and he never smoked in his 60-odd years of quality life.

If you spent 100 quid on that kit Richard mentions above and you find it isn't, that kit was still well worth buying. I didn't know you could get a kit to be honest, I'll certainly remember that.

Note that there are different versions of asbestos and one (might be two) are not harmful. I think if I remember rightly they go by colours, blue, brown and something else, though I dare not guess which one is the safe one, and the colours don't related to the actual colour of the material, it's just how the identify between the few types.
