Replace a lamp holder on a pendant

Isolate the circuit, prove it's dead, then swap the old lamp holder for a new one and restore power safely.

LH-01Turn off the light and gather your toolsFlick the wall switch off first, but don't trust it alone — a switch only breaks one wire, not the whole circuit. Get everything ready: a voltage tester, insulated screwdriver, wire strippers, and the new lamp holder. Match the new holder type to the old one — bayonet (BC) is by far the most common in UK homes, but check if yours is Edison screw (ES).

LH-02Isolate the lighting circuit at the consumer unitGo to your consumer unit and switch off the MCB (breaker) for the lighting circuit. If you're not sure which one it is, turn off the main switch instead so the whole house is dead. Leave a note or tape over the switch so nobody turns it back on while you're working. Never work on a pendant with the circuit still live, even for a moment.

LH-03Prove the circuit is dead at the ceiling roseBefore touching any wires, use your voltage tester on the terminals inside the ceiling rose to confirm there's no power present. Test between live and neutral, and live and earth. If you get any reading at all, stop and go back to the consumer unit — you've switched off the wrong circuit.

LH-04Lower the pendant and photograph the wiringUnscrew the outer cover (skirt) on the lamp holder and slide it down the flex to expose the terminals. Take a clear photo of how the wires are connected before you disturb anything — this saves guesswork later. Support the fitting so it doesn't hang by the wires alone.

LH-05Disconnect the old lamp holderLoosen the terminal screws and free the flex from the old lamp holder. Older fittings sometimes use red and black wire colours instead of modern brown and blue — brown/red is live, blue/black is neutral. Set the old holder aside for disposal.

LH-06Check and prepare the flexLook at the flex for any scorching, cracking, or brittle insulation — if you see this, replace the flex rather than reusing it. If the flex is sound, strip back around 10mm of insulation from each core if the old ends look tarnished or frayed. Thread the flex through the new lamp holder's cord grip before connecting anything.

LH-07Connect the new lamp holderConnect live to the terminal marked L and neutral to the terminal marked N, matching the photo you took earlier. Most plastic bayonet holders have no earth terminal — that's normal for an all-plastic fitting. Tighten each terminal screw firmly, then tighten the cord grip so any tug on the flex pulls against the grip, not the terminals.

LH-08Reassemble and rehang the pendantSlide the outer skirt back up over the lamp holder and screw it together. Hang the light shade or flying saucer plate back on if you removed it, and make sure the flex sits neatly with no twists or strain.

LH-09Restore power and testSwitch the circuit back on at the consumer unit, then turn the wall switch on. Fit a bulb and check the light works properly. If it flickers or doesn't come on, isolate again and check your terminal connections before trying a different bulb.

LH-10Tidy upDispose of the old lamp holder and any offcut flex — small electrical parts like this go in general waste, not recycling. Pack away your tools and give the area a quick check for any dropped screws or debris.
