Good day

We recently installed LED downlights in our house and after 5 months are already having to change the lights. When I took the light out I noticed that it had been connected using insulation tape and not a screw connector as I would have expected (pictures attached). They produced a post completion COC, but I am concerned that this type on connection is not compliant and a potential fire risk.
I would appreciate any advice on this.

Regards
Greg
