What you'll need
Never change a light fitting without isolating the circuit first. A ceiling rose carries live voltage even when the light switch is off.
Step-by-step guide
- Isolate the circuitSwitch off the lighting circuit at the consumer unit. Turn the light switch on — if the light doesn't come on, the circuit is off. Then turn the switch back off (so power can't be accidentally restored).
- Test with a voltage testerRemove the old fitting's cover. Test all wires with your voltage tester pen before touching any of them. If any show live, the circuit is not properly isolated.
- Remove the old fittingDisconnect the wires, noting which goes where (or photograph them). Unscrew the fitting from the ceiling rose or backplate.
- Check the ceiling rose or backplateIf the ceiling has a standard UK loop ceiling rose, you may find multiple sets of wires — this is normal. If the existing fitting has a connector block rather than a ceiling rose, you'll just see one set of wires.
- Connect the new fittingFollow the new fitting's instructions. In most cases: brown (live) to L, blue (neutral) to N, green/yellow (earth) to E. In older houses you may find red (live) and black (neutral) — the connection principle is identical.
- Fit and testSecure the fitting to the ceiling following the manufacturer's instructions. Restore power and test.
Before buying a new fitting, note the weight and check how it fixes to the ceiling. A statement chandelier may need additional structural support that changes the scope of the job.
Expert tips for the best result
- Heavy light fittings need to be anchored to a joist or fitted with a specialist toggle bolt — the plasterboard alone won't support them
- LED bulbs generate far less heat than halogen — they're compatible with all modern fittings
- Bathroom light fittings must carry an IP rating appropriate for the zone they're in — not all light fittings are bathroom-safe
- If you see a green mastic ring around the old fitting, it's been soundproofed — replace it
- Smart bulbs in a standard fitting are the easiest way to add smart lighting without any rewiring
