Installing boilers has become a two trade installation with the Part P unless you are trained. The electrical conection from the boiler needs to come from a fused double pole isolator (spur). I have noticed that there are installations where the use of a plug is used direct into a unswitch shuttered socket outlet. I find this way is much better as the polarity and if there is a short can be tested easily with a multimeter. If the installation was from a spur then you would have to off the electrics of the house in that area and take the wire of the spur in the wall then test, VERY TIME CONSUMING but needs to be done !.

Some boilers state in there instruction manuals that unswitch shuttered socket outlet can be used.

I want to know if this method can be used for all Domestic boilers even if it doesn't say in the manufatures instructions as it does comply with Electrical regulations?

i am a registered installer

Normally the boiler would be connected via a fused spur.

As for part P, and I spoke to CORGI about this, an RGI can carry out electrical work from and including the fused spur without part P, as this is covered in the ACS assessments. Before the fused spur you need an electrician

thanks for your reply.

Can you please explain what you meant by 'Before the fused spur you need an electrician'.
I would appreciate it if you can explain more on what i can and cant do being a RGI?

Due to the easyness of testing the boiler and the safety aspect of elimanating the electric totaly from the boiler and having no suspect current an unswitch shuttered socket outlet would be best.

BUT we do need to follow the BS and Regs [color=red][b]so is this acceptable with all boiler manufacturers[/b][/color][b][color=red]?[/color][/b] I had called a boiler manufacture if the plug conection would be acceptable as it did not say in their MI. They said it is accptable to install an unswitch shuttered socket outlet/Plug conection.

'Can you please explain what you meant by 'Before the fused spur you need an electrician'

Connection to and the wiring between the consumer unit and the fused spur should be carried out by an electrician.

From and including the fused spur for the central heating, the timer/programmer, pump, three port valve, boiler etc etc etc is RGI territory - sometimes electricans wont work on CH installations.

'BUT we do need to follow the BS and Regs'

Of course we do, like I say, i've enquired a few times about Part P, to receive a few responses - all boiling down to RGI's can work on electrical installations and install from a fused spur, without part P.

I have never installed a boiler using a plug as the electrical connection, I always connect into a fused spur with 3amp fuse. That's the best way.
