Short answer

Stop using that light and switch it off. If there is smoke, a strong burning smell, crackling, or heat from the fitting or ceiling, get everyone out, stay out, and call 999.

Do not do these things

Don’t keep turning the light on to test it.
Don’t touch the fitting, ceiling, bulb, or lampshade if anything feels warm, smells burnt, or looks damaged.
Don’t change the bulb or lampshade, or try to tighten anything right now.
Don’t remove the fitting, pull at cables, or open anything electrical yourself.
Don’t cover the area with insulation, paper, paint, or fabric to hide it.
Don’t ignore it just because the light is still working.

What to do now

From a safe position, do a quick danger check: look for smoke, a burning smell, crackling or buzzing, flickering, or heat around the fitting or ceiling.
If there is smoke, flames, a strong burning smell, crackling, or the ceiling is hot:
- get everyone out;
- close doors behind you if you can do that safely;
- call 999 and say you may have an electrical fire.
If there is no active danger, make the light safe for now:
- turn the light switch off and leave it off;
- if you can do it safely, with dry hands and without climbing or reaching awkwardly, switch off the relevant lighting circuit at the consumer unit;
- if you are not sure which circuit it is, keep the light switch off and wait for an electrician, unless smoke, heat, crackling, or a strong burning smell starts.
Keep the area clear: move paper, curtains, bedding, boxes, and other easy-to-move items away from the fitting and the area underneath it.
Arrange a qualified check:
- if you rent, contact your landlord or letting agent and say: “There are scorch marks around a ceiling light fitting; possible overheating; the light is switched off.” Ask for a qualified or registered electrician urgently and keep the light off until it has been inspected;
- if you own the home, contact a qualified or registered electrician and describe where the marks are, whether there was any smell, sound, flickering, heat, or tripping, and whether the bulb, shade, fitting, or loft insulation has recently been changed.
Document without touching: take a wide photo and a close-up photo, and note when you first noticed the marks.
Escalate if anything changes: if smoke, heat, crackling, or a strong burning smell appears, stop dealing with the fitting, leave the property, and call 999.

What can wait

You don’t need to work out the cause right now.
You don’t need to decide whether it is the bulb, the fitting, the wiring, a downlight, insulation, or decoration marks.
You don’t need to clean, paint over, or cover the marks yet.
You don’t need to contact insurers immediately unless there has been a fire, serious damage, or the electrician advises it.

Important reassurance

Scorch marks around a light fitting are a valid reason to stop using it and get it checked. Turning the light off, keeping the area clear, and arranging an electrical inspection are sensible first steps.

Scope note

These are first steps only, to stabilise the situation and avoid making it worse. The cause and repair need an in-person check by a suitable electrician.

Important note

This is general safety information, not a substitute for an in-person electrical inspection or professional advice. If you think there is any immediate fire risk, prioritise getting to safety and calling 999.
