What could be causing this?
A bulb that blows occasionally is normal. Blowing repeatedly in the same fitting, or several at once, is not — there is an electrical cause behind it.
Voltage spikes
Fluctuations in the grid or in the house wiring drastically shorten the life of bulbs, especially LEDs.
Poor contact in the holder
An oxidised or loose lamp holder heats the base of the bulb and makes it blow long before its time.
Faulty lighting circuit
Damaged wires or badly made connections in the circuit blow several bulbs in the same part of the house.
Low-quality materials
Cheap bulbs and transformers last a fraction of what is advertised. We use long-life materials.
What to do right now, while the electrician is on the way
Simple steps to protect your home and your family
- 1
Turn that light off at the switch
If the bulb blew with a crack, a spark or smoke, leave the switch off until the technician visits.
- 2
Do not leave the holder empty
A lamp holder with no bulb on a live circuit has exposed contacts — dangerous, especially with children in the house.
- 3
Notice the pattern
Is it always the same fitting? Do several blow at once? That information helps the technician go straight to the cause.

Frequently Asked Questions
Is it worth calling an electrician just to change bulbs?
When they blow repeatedly, yes — the problem is not the bulb, it is the installation. We are also called out for fittings in high ceilings, stairwells, wall lights with integrated LEDs and bulk replacements (houses, offices, apartment blocks).
Do you swap old lighting for LED?
Yes. We replace halogen and fluorescent with long-life LED, saving up to 80% on energy. We give you a fixed quote before we start.
Why do LED bulbs blow when they are supposed to last for years?
Almost always because of voltage spikes, incompatible transformers or poor contact in the holder. The technician measures the circuit voltage and corrects the cause — from then on the LEDs last as advertised.
Do you do the work the same day?
Yes. Replacing bulbs and checking the lighting circuit is finished on the first visit in the vast majority of cases.
