I'm looking for a tradesperson to install a new light switch in my living room. The wall currently has an existing single switch and I want to replace it with a modern, dimmable switch compatible with LED bulbs. The job includes turning off power safely, wiring the new switch, and testing the circuit to ensure proper operation. Helpful to have experience with UK/Ireland electrical standards. Please confirm if you can supply the switch or if I should provide one. I’d prefer a daytime appointment and a brief explanation of what you’ll need from me before you start.
