Minor Works on new Thermostat

[PliersForHire]

Hi All

I have been asked to supply a minor works certificate on a smart thermostat upgrade.

Would I just test the dedicated circuit from the CU to the spur or does it involve all wiring attached to the wiring centre?

Cheers PFH.

Its always awkward with a minor works, they are designed to be issued when you have modified a circuit, say adding another socket or additional lighting etc, This involves installing extra cable so it alters the original test results. A minor works just establishes the fact that the circuit is still compliant after the alterations.

If you just change an accessory like a thermostat or socket front then there isn't any modifying going on so how do you fill in the boxes for the modified circuit bit. IMHO it shouldn't be necessary to issue a minor works if you are just changing an accessory.

Hi Oscar

I can't get round having to do it unfortunately.
I just didn't know how far to go with the test and if I did have to include every wire, how would I enter that on the form?

You can obviously put N/A in some of the boxes like the cable size etc because you haven't used any, you can do a loop test at the thermostat and enter that value, same with the RCD if it has one. As for the megohms well you shouldn't have to dismantle the consumer unit and start testing the complete circuit really, imagine changing a broken lamp holder on a pendant then having to disconnect the circuit, take every other bulb out of that circuit, start meggering everything whilst operating the two way switching etc. Thats not exactly what I would call minor. So I just enter the values for our new bit of cable if we have used any, if not I just put N/A in most of the boxes.
