Electrical Question

Kitchen cabinet lighting

I want to install additional lighting over worktops but the nearest electrical point is the switch for the cooker extractor fan (the lighting in this is insufficient). Can I take a spur from this to power a new socket? Presumably I cannot wire directly to the existing switch? I have not bought the lighting yet so flexible on options.

It is possible to spur of the extractor supply, but only if the existing extractor forms part of a ring final circuit, and is not already a spur.
However to confirm that it does form part of a ring final circuit, the supply would have to be tested, to confirm continuity of ring final circuit. This should be done by someone who is competent in testing.

As you're planning on doing DIY electrical work in the kitchen, you firstly must apply to your local authority and pay the relevant fees to get Part P building regulation consent to do the work. This is because it has been illegal to carry out DIY electrical work in the home since 2005.

Once you have consent in place you can proceed. All cables will need to be RCD protected (as now required by BS7671:2008 wiring regulations and the local authority inspector will check this for this when they call to test and sign off the work.)

Assuming that all your existing wiring is RCD protected, then you can't really take a spur off of the cooker circuit. The best option is to locate a socket that is on the ring circuit and is not already itself a spur, and take a cable from there to the new fused spur.

As per the regulations cables must be run in safe zones (refer to BS7671 for details) and adequately protected.

On completion of the work, contact your local authority to come and check and sign off the works and issue a Part P building regulations certificate. See link below
