What we install.

Six core downlight specifications cover ninety-five percent of jobs — kitchens, bathrooms, hallways, stairs, period properties and smart-controlled open-plan rooms. Every fitting matched to the room, the regs, and the dimmer.

01

Mains-voltage GU10 LED

5W warm-white dimmable GU10 LED lamps in standard fire-rated housings. The workhorse fitting for kitchens, hallways and staircases. Trade-grade Aurora, Integral, Saxby or Collingwood — not £3 import.

02

24V LED strip + driver

Constant-voltage 24V LED tape on aluminium heatsink profile, fed by a properly sized driver. Under-cabinet, plinth, alcove and accent lighting. CRI90+ tape only — soft-start dimming so it doesn't flicker at low levels.

03

IP65 / IP44 bathroom

Sealed IP65 LED downlights for Zone 1 above bath and shower. IP44 in Zone 2. Driver mounted outside the zone. Every circuit on a 30mA RCD. BS 7671 Section 701 special-locations compliant.

04

Adjustable / tilt downlights

Gimbal-tilt fittings to wash walls, accent paintings, pick out beams, or light period features in heritage homes. Aimed and locked at install. Low-glare baffle options for snug rooms and bedrooms.

05

Fire-rated downlights

Required between floors. Intumescent gasket expands to seal the cut-out under fire conditions. FR60 (60-minute) and FR90 (90-minute) options matched to the building's fire-resistance rating. Building Regs Approved Document B compliant.

06

Smart downlights

Hue White and Color Ambiance smart GU10s, or Hive compatible dimmable circuits. Scene control, voice control, schedule-based dim from Alexa or the Hue app. We wire the dimmable feed; the smart layer sits on top.

Common downlight questions.

Do downlights need fire-rated housings?

Yes — wherever a downlight is recessed into a separating floor or ceiling between two storeys, it must be fire-rated to maintain the fire integrity of the floor. We use FR60 (60-minute) or FR90 (90-minute) fittings with intumescent gaskets, matched to the building's required fire-resistance rating. Required by Building Regulations Approved Document B and BS 476 Part 21. We never fit a non-fire-rated downlight in a separating ceiling, even if the previous installer did.

Are LED downlights safe in bathrooms?

Yes — provided the IP rating matches the BS 7671 zone. Zone 1 (above the bath/shower) needs IP65 minimum. Zone 2 (within 0.6m of the bath) needs IP44 minimum. Outside the zones, IP20 is technically permitted but we always specify IP44+ as a sensible margin against splashes and steam. The driver must be kept outside Zone 2, and every bathroom circuit runs on a 30mA RCD. We do not use cheap import IP-rated fittings — the seal degrades and the rating becomes meaningless within a couple of years.

Will my dimmer switch work with LED downlights?

Only if the dimmer and the downlight driver are matched. Old rotary dimmers designed for 50W halogen lamps will buzz, flicker, or fail to dim properly on LEDs. We specify trailing-edge LED-rated dimmers (Varilight V-Pro, Click Scolmore Deco LED, Hamilton specifier) matched to the chosen downlight driver — leading-edge, trailing-edge, 0–10V, or DALI as required. Every install is dimmed and tested across the full range before sign-off. No buzz, no flicker, smooth fade to off.

Can downlights be installed without rewiring the room?

Often yes. If you have an existing lighting circuit in good condition with a single ceiling rose, we can usually convert it to a downlight scheme by tapping into the existing feed, dropping a junction box above the ceiling, and wiring out to the new fittings on a switched and dimmed loop. Where the existing wiring is rubber-insulated, twin-and-earth without a CPC, or the circuit is already on a non-RCD-protected fuseboard, we'll quote the additional remedial work upfront. Free survey to find out which scenario applies to your room.

What's a fair price per downlight?

For a single fitting added to an existing circuit, expect £45 + VAT. For a 6-fitting kitchen retrofit on a new dedicated circuit (chase, wire, hole-cut, fit, certify), £350 + VAT is typical — that's about £58 per fitting all-in including the fittings themselves at trade. A 12-fitting open-plan with two switching zones is around £650 + VAT, ~£54 per fitting. Anyone offering whole-house downlights at £20 a unit is either using sub-£3 import fittings or skipping the testing and certification — both will cost you when the EICR comes around.
