Why do my bathroom lights keep tripping the RCD?

Bathroom light RCD tripping is usually caused by moisture in a light fitting, a shaver socket fault, or an extractor fan issue — all need to be checked and repaired.

Why has one light circuit stopped working?

A tripped MCB, blown fuse, or a broken bulb at the start of a loop circuit are the most common reasons a whole lighting circuit goes off.

Can I replace a pendant light fitting myself?

Yes — replacing a like-for-like pendant light fitting is a minor electrical task a competent homeowner can do safely, provided the circuit is isolated first.

Why has my bathroom light stopped working?

Usually a failed bulb, a tripped circuit, or moisture damage to the fitting. Bathroom lights must be IP-rated — do not replace fittings yourself.

Why do my lights keep flickering?

Usually a loose bulb, incompatible dimmer switch, or a loose connection. If it is more than one room, call an electrician.

Why do my LED lights flicker?

LED flicker is usually caused by an incompatible dimmer switch, a loose connection, or a failing LED driver. Most cases are easy to fix.

Why will my LED bulbs not dim properly?

Your dimmer switch is not compatible with LED bulbs. You need an LED-compatible trailing edge dimmer or dimmable LED bulbs.

Why do LED lights flicker when switched off?

Because something is letting a tiny current reach the lamp even when “off”. Common culprits are: - Illuminated or smart switches and some dimmers that leak a small standby current. - Capacitive coupling in long or parallel cable runs (especially 2‑way switching), creating a “ghost” voltage. - Poor‑quality LED drivers that react to microamps of leakage. - Shared/borrowed neutrals or wiring errors that back‑feed the lamp. That minuscule current slowly charges the LED driver until it discharges as a brief flash, or it keeps the LEDs glowing. Typical cures: replace illuminated/smart/two‑wire dimmers with LED‑compatible or 3‑wire types, fit an anti‑flicker RC snubber across the lamp, use better lamps/drivers, correct neutrals/polarities, or shorten/change cable routes where practical.

Why has my outdoor security light stopped working?

Usually a failed bulb, a faulty PIR sensor, or moisture damage. Outdoor lights must be IP66 rated. Check the sensor settings before calling an electrician.

What is a two-way light switch and how does it work?

A two-way switch lets you control one light from two different locations — common on stairs and hallways so you can switch a light on at the bottom and off at the top.

Why do my lights dim when I turn on an appliance?

Lights dimming briefly when a large appliance starts is usually caused by high inrush current — it's mostly normal, but severe or sustained dimming indicates a wiring or supply problem.
