Domestic Installer - a scheme that covers general electrical installation work in UK domestic properties only

Sergio Fernandez

Domestic Installer - a scheme that covers general electrical installation work in UK domestic properties only.  But what if the dwelling has 3 phase due to size of house or for Solar PV or EV (Electric Vehicle or HP (Heat Pump)?


Eg 

Single phase safe isolation 3 point test at 230v AC nominal

3 phase 10 point test but at some point phase 1 to phase two at potentially 400v AC


As always please be polite and respectful in this purely academic debate.





Come on everybody let’s help inspire the future

  • The electrical installations in Grenfell Towers were all domestic installations, all the installations within the flats and the landlords halls, stairs, and communal areas come under the Notification Requirements in Part P of the Building Regulations, including any fire sprinkler systems and the like.

    That's a good point, but do sprinklers not fall under Part B?

    Two sets of certificates will be required one covering the fire sprinkler system electric installation design, installation and testing, and another to cover the actual fire sprinkler system design, installation and testing.

    The installation electrician may only be signing certification for the electrical installation work and maybe the testing if they did not design the electrical installation.

    Domestic electrical installations can be huge and involve many different people contributing to the design, installation and testing.

    I think that here some are using the phrase 'domestic installer' as a diminutive, for someone who only does minor works, adding the odd new socket or a fused spur for the extractor fan, or installing alarms or something, perhaps by dint of lesser experience or qualification. Sort of thing alluded to here

    "It is important to note that a domestic installer is not an electrician. "

    which strikes me as an odd thing to say...

    I also thing the rest of us are using it as 'person who designs and installs on domestic property' - which can as alluded above be almost unlimited in complexity and disagree with that definition.

    That article was published more than twenty years ago, new requirements are coming into force on the 1st January 2025 which are far more stringent.
