look at the latest npcc force policy.
however it will probabky become mandatory for installers but isnt yet. Plus my vote on comitee currently is i want a documemt that has some industry input. cyber essentials does not and has little to do with intruder alarms and alarm companies. i say little not nothing.
Hi Scott
Im afraid the above quote isnt 100% true. Previous force policy had this as a requirment but is now optional.

I'd say no rad can heat up quick enough I wouldn't worry about it say it. Above yes is an issue. The only force that can defeat the 1.6-2.4 degree a second change is our Sun. Apart from open fires and log burners. Tldr don't worry about radiators
yeah dont use them anymore but when i did, strip in the normal way (leaving some insulation to twist tight) then wrap around a 2.5mm terminal driver, remove screw and washer and push through loop of cable making sure to keep so when it tightens it doesnt loosen the coil.
Bear in mind that switch mode psu add what looks like induced ac.id be interested to see what a new psu does. Mine is knacked cos I've overloaded it lots in testing.
or try removing the ac power (pull fuse) for a bit and see if it continues when on battery only. Also measure your induced ac with the mains off to see the difference between the psu on and off
