Electrical Safety Advice for Downlights

Downlights usage and safety

Downlights are an attractive way to brighten up your home, but poorly installed ones are the cause of a significant number of fires in homes every year.

Downlights (recessed luminaires) are light fittings installed into ceiling openings so that the unit sits flush with the ceiling surface, giving a clean and unobtrusive appearance rather than projecting below it.

They may operate directly at mains voltage (230 V) or be supplied via a transformer or driver at extra-low voltage (typically 12 V). Extra-low voltage (ELV) downlights are often referred to as “low voltage” on product packaging.

Downlights are also available as fire-rated fittings. These incorporate features that help maintain the fire resistance of the ceiling by sealing the opening in the event of a fire, slowing the spread of fire and smoke to adjacent areas.

Fitting replacement lamps

Always read and follow the manufacturer’s instructions.
Check both the packaging and the downlight fitting for details of the correct replacement lamp type and maximum wattage. Don't exceed the stated rating.
Where LED lamps or integrated LED downlights are used, ensure any replacement lamps or components are compatible with the fitting and driver.
Always switch off the electrical supply before replacing a lamp.
Don't install a cool beam (dichroic) reflector lamp unless the downlight is specifically designed for that type. If in doubt, use only aluminium reflector lamps.
If the lamp holder or fitting shows signs of damage, overheating, corrosion, or discolouration, don't install a replacement lamp. Seek advice from a registered electrician.

Installing downlights

For all downlights installed into ceilings, it is recommended to use fire-rated fittings to maintain the fire integrity of the ceiling.
Where LED lighting is installed, integrated LED fire-rated fittings or suitable fire-rated housings should be selected to reduce heat build-up and improve energy efficiency.
Where traditional lamps are used, aluminium reflector lamps are recommended to help manage heat output.
All fittings should be designed and installed to minimise heat transfer into ceiling voids and support compliance with fire safety requirements.
It is also recommended that a registered electrician carries out the installation of downlights.
Manufacturer’s instructions should be retained for future reference, for example when replacing lamps or maintaining the fittings.

Maintaining downlights safely

Check the visible markings on downlights to confirm the correct lamp type and wattage.
If cool beam (dichroic) lamps are fitted in downlights intended only for aluminium reflector lamps, they should be replaced with the correct type.
Where LED downlights are installed, ensure any replacement lamps or components are compatible with the fitting.
Ensure downlights installed within ceiling or floor voids have adequate clearance around them to allow for safe heat dissipation.
Do not allow downlights to come into contact with, or be covered by, loft insulation or combustible materials unless they are specifically designed and rated for such conditions, for example insulation-contact or fire-rated LED fittings.
Check that downlights are positioned at a safe distance from furniture, curtains, or other combustible materials.
Regularly inspect downlights and surrounding areas for signs of overheating, such as discolouration, scorching, or curled labels.
Faulty or overheating fittings should be replaced promptly.

ALWAYS

Use a registered electrician to install downlights.
Ensure downlights have adequate clearance around them to allow heat to dissipate safely.
Regularly check downlights and surrounding areas for signs of overheating, such as discolouration or scorching.
Switch off the electrical supply before replacing a lamp.

AVOID

Using cool beam (dichroic) lamps in downlights designed only for aluminium reflector lamps.
Covering downlights with loft insulation or any combustible materials, unless the fittings are specifically rated for that use.
Replacing a lamp where the holder or fitting is damaged, scorched, or corroded.
Exceeding the maximum rated wattage or using incompatible replacement lamps, including unsuitable LED lamps.

Stay safe with electrical products

Check plugs and sockets

Don't ignore burn marks, ‘arcing’ (buzzing or crackling) sounds, fuses blowing, circuit-breakers tripping, or if it feels hot to touch.

Unplug and contact the retailer, manufacturer, or a qualified repair technician.

Protect with an RCD

An RCD (residual current device) in your consumer unit (fusebox) protects you from electric shocks if a product is faulty.

If you don’t have RCD protection, use an RCD plug on the socket where the product is plugged in.

Fit smoke and heat alarms

Ensure there is at least one smoke or heat alarm per floor in your property. Fit enough alarms to cover all areas where a fire could start.

Test alarms at least once a month. Replace them every ten years or when the replace by date is reached.

When does a periodic inspection need to be carried out?

It is recommended that periodic inspection and testing is carried out at the following times:

for tenanted properties, every 5 years or at each change of occupancy, whichever is sooner
at least every 10 years for an owner-occupied home
at least every 5 years for a business

The Landlords and Tenant Act 1985 requires landlords of properties with short leases to keep the electrical wiring in repair and in proper working order. We recommend landlords arrange for periodic inspection and testing to be carried out by a registered electrician at the relevant intervals shown above.

Periodic inspection and testing of the electrics should be carried out more frequently on the places and premises listed here:

3 years for a caravan
1 year for a swimming pool

Who should carry out a periodic inspection?

Periodic inspection and testing should be carried out only by electrically competent persons, such as registered electricians.

My electrician told me that they were registered; however I now believe that they are not, as they have not given me a certificate. What should I do?

First, you need to find out whether the electrician you used is actually registered. To do this, contact the operator of the scheme they have claimed to be part of, and they will tell you whether this is the case. If they are registered, the scheme operator can guide you through their complaints procedure.

If you find out the electrician misled you and is not registered, you should report this to your local Trading Standards Department as they are breaking the law. We would also recommend that you get an Electrical Installation Condition Report (EICR) carried out on your home; this will assess any work that has been undertaken and will act as sufficient documentation to certify that work. This needs to be carried out by a registered electrician and unfortunately will be an added cost for you.

Has your electrical product been recalled?

Electrical products are recalled more regularly than you might think, but the response rate to a recall is often worryingly low. This means there are potentially millions of recalled electrical items still in UK homes.
