    Was going through fuse board to work out which fuses apply to which sockets/lights etc in secondhand house and found 1st floor lights also connect in to the gas boiler in an extension previous owner added. The alarm company also used the same circuit to power alarm panel.



    As this is a lighting circuit it has a 10A breaker like the other lighting circuits.
    Its not causing any problems - ie everything works, but is this something I should get an electrician to fix ?

    Not ideal but not that big a deal. Do you mean fuses or MCBs? If fuses the installation may be very old and may require a serious upgrade.

    Most alarm installers are not qualified electricians so they should not work on a distribution board. I would be concerned about this. The electrical load from an intruder alarm is minuscule though.

    I would certainly get the wiring looked at but having all of these on the same circuit is not not necessarily a big deal in my opinion. But you are right, it would be best if they were split up.

    It’s common enough to come across this type of installation on older houses as this was a regular way of wiring.
    In newer institutions rcd protection is a requirement (specifically for the circulation pump) so its best practice to provide a dedicated circuit with rcbo protection.

    This is true, but it is important to note that new rules can not be enforced retrospectively.
