Question on wiring

[Neil K]

Looked at a job recently, found Honeywell actuator on zone valve for HW not working. Went to investigate further, had to pull out a washing machine and a dryer to get to the wiring and test what was faulty
Everything was wired in higgledy piggly into connector blocks, no insulation tape wrapped around it to protect it from any leaks (boiler Keston c25 directly above)
Nightmare of a spot to try and get in and test with multimeter. Managed to establish cylinder stat was reversed as only got 240v going to actuator (still not working though) when turned it down to 0 and vice versa. Told customer all the wiring needled to be brought up into an accessible place and wired in properly into a wiring centre, will be replacing honeywell actuator, cylinder stat (only erring on side of caution, because it's a cheap Mickley mouse one I've never seen). I didn't see a fused spur anywhere bit the previous boiler was in the loft so it's probably up there, I plan to move that down aswell and put it with rest of controls.
I'm perfectly confident doing all this, my question is do I need to be Part P qualified to do it?
Thanks

My understanding is yes. You can replace like for like, so changing actuator in wiring in new one, or changing cyl stat, but if you are required to put in new switches, running cables etc then you need Part. P. That's what I've been led to believe and always gone with.

yes you do need to be registerd to do the work, tho it sounds like you would be doing them a favor sorting it out to the correct standards.

TBH you will struggle to find a sparks who would cert the work anyway as from my experience they dont bother unless its re wires or major upgrades.

think you would be alright if you dont move the fused spur. Im sure its not considered fixed wiring from there

probably done by a sparky in the first place

Thing is, it's up and down to the loft to isolate and test now. I spoke to a sparks at work, he said just junction box it properly in the loft and make sure junction box is fixed visible and marked clearly with a sticker or whatever stating old boiler supply now moved downstairs.

Oh without a shadow of a doubt

If you can find where the cable comes from you might be able to just cut it back to the airing cupboard or where ever

Yes but if that's not feasible just leave it where it is......Real world yes.....in theory no

could always put a sticker on the boiler saying electrical isolation in loft, ive done it on a new build when the sparks wired the fuse spur in the A/C and put a blank spur next to the boiler but it was feeding a kitchen appliance. I thought some engineer will switch this spur off and put his fingers in the pie.
