Not for you to do a risk assessment as you cannot possibly foresee circumstances. Plastic light switches are not type tested as a Class II accessory.
 
This guy seems to be getting a lot of stick for basically making the best of a bad job?

However high and mighty we electricians might think we are, and however misguided customers may be, we can't force people to have work done if they don't want it!

The result in this scenario is an upgrade of CU, which will include 30ma additional protection, and the removal of metal accessories for plastic, which type tested or not, will be inherently safer.

End product is a safer installation, if an imperfect one. The other option is to keep going with the high and mighty act, and walk away potentially leaving 3036's and metal switches! I think I know which route I would take....

I walk from jobs like this unless the client accepts any rewiring as necessary. You advise and if they decline, walk away.

All lights and switches without a earth present were changed to class 2 and all switches DO have screw caps fitted.

The customer had recently had all the rooms decorated and didn’t want any damage to be made to walls/ceilings so changing to class 2 was the only option.

I hope you are not stating you have fitted Class II switches because this is far from the case. Aside from the fact plate switches are not Class II the metal fixing screws require earthing and fitting plastic caps in no way provide any level of double insulation. A better option would have been Nylon screws.
 
Not that I know of I should imagine production stopped a long time ago due to lack of demand.
 
It was a method used a fair few years back and if the installation has light fittings which do not require an earth then it was acceptable and would still be so now.
 
@westward10 .I am responding to my disagree on two of your posts as you will be asking me why shortly:(.
Plastic switches might not be class 2 rated but last time I checked they don't conduct electricity so you cannot get a shock off them.As for nylon screws FFS.Get a grip.In 34 years of being an electrician I have never seen nylon screws fitted in this instance.Plastic caps are fine for covering metal screws.We live in an imperfect world and sometimes have to make the best of a bad job.If you walk away from every job that you disagree with then you wouldn't be in business very long.The OP's solution is the best of a bad job.It is now 10 times safer than when he started and if the customer doesn't want to pay to have it rewired then he has done everything he can to make it as safe as possible.
 
Whether it is ten times safer is neither here not there, plastic caps are not type tested to provide any form of insulation they are merely for aesthetic purposes and if you think they are fine for covering a screw which should be earthed then you are naive.
 
I will be tearing down your new laura ashley wallpaper to put a mysterious extra wire into your fancy b and q light fittings, and you will pay me for the privelidge!

A note for the OP about the risk assessment: I am not sure how you computed the risk with original control measures. You indicate that it is likely that people using the electrical installation will get a shock, and some of them might be killed. Then you consider this only a medium risk! Likely x Severe = Very High Risk. In reality the likelihood is low, otherwise thousands of people would have been killed by unearthed lighting circuits which were once the norm.

I won't participate in the debate about whether the new configuration is acceptable. I'll stick to my earthed metalclad industrial wiring systems.
