01Where you control the lights
Think about where you enter the room and where you want to operate the lights, including from a bed or another doorway. Decide whether you need on/off control, dimming or separate lighting groups. Replacing one switch and adding another control position can involve different wiring work.
02Lights and dimmers that work together
Share the lamp or fitting models, the number of lights and any driver or existing dimmer details you already have. The lights and controls need to work together at a suitable load. A fitting marked as dimmable still needs a compatible dimmer for reliable LED operation.
03Switch position and wall access
Choose your preferred faceplate finish and explain whether the switch is staying in the same position. The available mounting depth, wiring and access affect which accessory can be fitted. Mention any decorating plans so the cable route and repairs to the wall can be considered together.
