Light flickering can have several causes: loose connections, incompatible dimmer switches (especially with LED lights), voltage fluctuations, or faulty bulbs. For LED lights with dimmers, ensure you're using an LED-compatible dimmer. Check all connections are secure. If flickering persists, consult a qualified electrician to check for loose wiring, voltage issues, or other electrical problems. Persistent flickering can indicate serious electrical issues.

Dimmer switch buzzing is usually caused by incompatibility between the dimmer and lights, especially with LED lights. Standard dimmers designed for incandescent lights can buzz when used with LEDs. Other causes include loose connections, overloaded circuits, or faulty dimmers. To fix buzzing, use an LED-compatible dimmer (trailing-edge) designed for your LED lights. If buzzing persists, check connections and consult a qualified electrician.

A non-working socket can have several causes: tripped circuit breaker or RCD, faulty socket, loose connections, or overloaded circuit. First, check your consumer unit for tripped breakers or RCDs and reset if safe to do so. If the socket still doesn't work, it may have loose connections or be faulty. Never attempt to repair sockets yourself - always use a qualified electrician. Faulty sockets can be dangerous and must be properly diagnosed and repaired.

A non-working light switch can be caused by: tripped circuit breaker, faulty switch, loose connections, or faulty bulb. First, check if the bulb works in another fitting and check your consumer unit for tripped breakers. If the switch feels loose or makes crackling sounds, it may be faulty. Never attempt to repair switches yourself - always use a qualified electrician. Faulty switches can be dangerous and indicate wiring problems.
