When to Add Covers for Old Downlights
Many older recessed downlights found in homes can benefit from an upgrade. As well as providing better light, downlights cut holes in ceilings and these can have implications for fire safety, heat loss and even how insulation can be safely laid in lofts. Downlight covers, sometimes known as hoods, can address these issues and that’s what this article explores.
1. When switching to LED
Moving from halogen downlights to LED is one of the surest ways to cut your lighting bills and the number of bulbs you replace. Even though LEDs are cooler running, it is still a good idea to use downlight covers.
A cover sits over the fitting in the ceiling void. It keeps dust and debris out, helps restore the fire resistance of the ceiling where the hole was cut and lets insulation be laid over the top without touching the fitting. For Downlight Covers, visit Thermahood.
2. When doing loft conversions or insulation upgrades
Many older halogen downlights can become hot and can potentially cause a fire in loft insulation laid against them. Instead, installers often cut out a section of loft insulation to create a gap around each downlight, which allows warm air to rise from the room below into the loft space. A suitable downlight cover allows loft insulation to be laid continuously across a downlight while keeping it safely clear of the light source, which is safer and helps to reduce heat loss.
Ensure that the cover that you choose is suitable for the fitting type and that insulation can be laid over it. Always follow the manufacturer’s instructions.
3. For fire-rated ceilings
Some ceilings have to resist the spread of fire for a certain time under the building regulations. Examples are the ceiling between a garage and room above, the ceiling between flats and some ceilings in loft conversions. Cutting a hole in a ceiling for a conventional downlight will weaken the fire resistant ceiling coverings. Fire-rated downlights or fire-rated covers can be used to reinforce the ceiling coverings around existing downlights.
If the old downlights were installed without adequate protection, then adding fire-rated recessed light covers when you upgrade the downlights to new ones is a practical way to put that right. If in doubt about whether a ceiling needs to be fire-rated, consult a qualified electrician or building control.
4. If you see gaps, damage or signs of heat
Gaps can form around ceiling light fittings over time, and ceiling light clips can fail. Older ceiling light fittings can become discoloured due to heat. Scorch marks to the ceiling, a brittle or loose fitting and dust and cobwebs accumulating around the edges of a ceiling light fitting are all indicators that the light and the space above it will require attention. Replacing old ceiling light fittings and fitting ceiling light covers will seal up the ceiling once more and reduce unwanted draughts entering the loft space.
5. For peace of mind
Even where the regulations do not require them, many people choose to use downlight covers on all downlights during an upgrade to reduce the risk of fire, and to enable insulation to go over the top of the hole in the ceiling.
When downlight covers make sense
| Situation | Why a cover helps |
|---|---|
| Upgrading to LED | Seals the ceiling, keeps dust out |
| Adding loft insulation | Lets insulation go over the fitting safely |
| Ceiling needs to be fire-rated | Helps restore fire resistance at the cut-out |
| Draughts or heat loss into the loft | Closes the gap around the fitting |
| Old, discoloured or damaged fittings | Good time to replace and protect together |
Frequently asked questions
Do LED downlights still need covers?
The principle is that even though downlights with LED sources do not emit as much heat as halogen downlights, the hole in the ceiling still allows heat, air and sometimes fire to escape. Therefore even though downlight covers are not always required by building regulations, they are often a good idea. Some modern LED downlight fittings are already fire-rated and designed to be covered, so check the product details.
Can I fit downlight covers myself?
Many light covers can be fitted from within the loft space, if you can safely reach them. First switch off the power. Any work on wiring or light fittings should only be carried out by a qualified electrician. Some forms of electrical work are subject to Part P of the building regulations in England and Wales.
