Why Are My Lights Flickering? Leeds Electrician FAQs

A single flickering light fitting is often the lamp itself, or an LED lamp paired with a dimmer that was designed for old filament bulbs. Swapping to a trailing-edge dimmer rated for LED loads solves a large share of these calls.

Flickering that affects several circuits or the whole house is different. It can indicate a loose connection in the consumer unit, a deteriorating supply cable, a poor neutral connection, or a problem in the supply head that belongs to the network operator.

Older Leeds properties with rubber or fabric insulated cable and 1960s-70s rewireable fuse boards are more prone to loose terminals, because heat cycling gradually loosens screw connections.

Treat these as urgent: a burning or fishy smell, buzzing from a switch or socket, warm or discoloured faceplates, or lights that dim heavily when an appliance starts. These are signs of arcing or overload, both of which are fire risks.

Professional fault finding uses insulation resistance, continuity and loop impedance testing to isolate the fault instead of guessing. That means the repair fixes the cause, not the symptom.
