You probably should also consider applying for trade access

Having read post 1 and then post 15, what trade are you in?

If you aren't certified yourself then grading is irrelevant, just quote for the best system to suit the customer's needs.

 

In relation to the insurance claim, that's for the customer to enquire with the insurer, no matter how honourable your intentions, you are complicating matters for both of you, just let the customer speak to his insurer about that.

 

Everything else you have listed is down to price and suitability.
