Lighting with upstairs and downstairs circuits

Hopefully you have registered the work with building control and paid for part P building consent already? Otherwise you could fine yourself being fined up to £5000. See link below: http://www.donttakethep.co.uk/ Ideally the upstairs circuit and downstairs circuits should be kept separate. You can wire the landing light to work from two positions using the conversion or conventional two way switching methodology. If its just a matter of having two separate cables each on a different circuit in the same switch enclosure, then that's allowable under BS7671:2008.

This is OK to do but alterations to the wiring of special locations as bathrooms are required to be notified to LABC and signed off as complying with regulations. Two routes for this are pay fees to council, do work and have the council check and pass work or pay registered electrician to either oversee work, test, issue certificate and notify for compliance certificate to be issued.

This is ok to do as only competent persons should touch electrical work and therefore safe isolation procedure should be carried out before any work on the circuits. Also lighting will have to be 3 plate wiring to ensure no neutrals are crossed to stop nuisance tripping on a dual rcd consumer unit. Hope this helps
