    Hi,

    My existing system boiler if fed via a fused connection unit off the ring final circuit, when the boiler is replaced is it a requirement/best practice, that the boiler is fed via a dedicated circuit from the consumer unit to the fused connection unit.

    Cheers

    Leaving it on the ring circuit is not "Best Practice". A dedictated circuit is.

    Rubbish.

    A 3A fused spur does not need its own circuit...

    Hi,

    If a new circuit is required I can get this sorted in advance of the boiler replacement.

    Thanks to the forum I now know is not an 'electrical' requirement, is the dedicated circuit preferred by plumbing professional trade bodies as best practice

    Nope aslong as there's a fused spur it doesn't matter a feed could even be taken off the lighting circuit if acceptable (loading etc)

    If you are having an electric boiler fitted, yes a dedicated circuit would be required ...but for a gas boiler absolutely not a requirement.

    I may be wrong but an elec boiler rated at 3kw should be fine ?

    Hum.... I wouldn't, sure if it had a 13A plug on it but anything with a load above 2 Kw should be on its own circuit

    Thanks guys for the clarity, in my case it is a gas fuelled system boiler, electrically everything is fine, so I’ll leave it as is, I just didn’t want to fall foul if some other requirement I wasn’t aware of that I could sort in advance.

    Surely that depends on what it is supplying.
