The breakers weren’t labelled which ----ed me off at the time so I labelled them all but forgot to check which circuit the...

    Worcester Bosch course on wiring for central heating systems

    I have just finished a 2 day course on 'Wiring for central heating systems' as my knowledge was fairly poor on this subject. It was well run, good lunch, finished on time and I learnt a lot.

    So I’m fitting an electric underfloor heating mat by pro warm. I was testing it for continuity between L N and got 88ohms which is what it should be according to the instructions. It says to do IR test at 500V but it doesn’t say between which colours. So I did L N and got 0.00ohms. Have I...

    Is bathroom underfloor heating still notifiable?

    All the specific guidance I can find stating that underfloor heating is notifiable seems to refer to an outdated version of Part P, and I’m trying to understand why generally everywhere still treats it as notifiable.
