Issuing a danger notice

I am due to finish on a job today where i have been doing some remedial works following an EICR ( done by another electrician ). Its a residential block consisting of several bedsits and communal areas. In the kitchen/utility there is a washing machine and a dryer both fed via a coin meter.

Part of the remedial work was to provide a means of earth to both of these meters as it had been picked up there was no cpc present. On closer inspection it turns out that although the meters look very much like a they are metalic housing they are infact not, and do not provide any means of an earth within themselves.

When i was looking at the meters my attention was instantly drawn to the shoddy install method ( will try to post pic ) and the fact that it seems live terminals could be accessed. Unfortunately the landlord of said property is more than happy to have let a resident have a play with the electrical installation and to be honest i cant get away from the property quick enough.

As you can hopefully see from the pictures his resident DIYer has cobbled together a form of barrier with some trunking to remove any immediate risk. Although the trunking lid can be removed without the use of a tool and the terminals accessed again. I am debating as to whether or not to issue a danger notice just to cover myself particularly as the landlord is happy for his DIYer to try and make a more permanent barrier once i have left site. Having seen his work i dont have much confidence in him. Is a danger notice the way to go im asking myself if im being OTT but at the end of the day as the last electrician to work on the system if somthing happened im sure people would be all to quick to point the finger in my direction
