How Much Does Smart Lighting Installation Cost? (UK Prices)
From £150 for a single smart dimmer to five figures for wired control — here's how smart lighting pricing actually breaks down in the UK.
Typical prices at a glance
Prices vary with hardware choice and wiring, but these are realistic 2026 ranges for professional installation:
- Single room (smart dimmer/module + setup) — £150–£300 installed
- Kitchen with new dimmable downlights + smart control — £600–£1,200 depending on the number of fittings and ceiling access
- Whole house, retrofit modules across 10–12 zones with hub, scenes and app/voice setup — £1,500–£3,500
- Whole house with new LED fittings throughout (like our Sevenoaks case study: 70+ fittings, 12 zones) — £3,000–£6,000
- Fully wired lighting control system (Lutron/Rako class) — from £4,000–£5,000 for a partial system; £10,000+ whole-house, best done during renovation
What moves the price
Four factors dominate the quote: the number of zones (each switch position needing a module adds hardware and labour); whether fittings are being replaced (new dimmable LEDs and downlight cutting add materials and time); wiring condition (no neutral at the switch means either no-neutral modules or minor rewiring); and the control ecosystem (mainstream hubs are affordable, high-end wired systems are not).
Access matters too — downlights in a ceiling with loft access above are quick; the same lights under a tiled bathroom floor are not. This is why we quote from a survey or a good set of photos rather than guessing.
Where the money is well spent
Spend on the rooms you live in after dark — kitchen, living room, main bedroom — and on quality dimming in those rooms, because flickery dimming is the number-one smart lighting complaint. Spend on the hub/platform (it's the part you'll live with for a decade). Save on rarely-used rooms, which can stay dumb or join the system later.
Retrofit systems are modular: a common and sensible path is to start with two or three rooms around £500–£800, prove you love it, and extend. We design schemes that grow this way deliberately.
Certification — the part cheap quotes skip
Replacing switches with smart modules is a circuit alteration; adding downlights can be notifiable depending on location. A registered electrician tests the affected circuits and issues certification, keeping the installation legal and your sale paperwork clean. It's included in our fixed prices — check any competing quote does the same.

Frequently Asked Questions
Is smart lighting worth it in a rental property?
For tenants: smart bulbs and plug-in lamps — take them with you when you leave. For landlords: generally not, beyond perhaps a smart heating/lighting combo in HMO common areas; standard quality LED lighting is the better investment.
Can I install smart switches myself to save money?
Swapping a switch involves live mains terminals and, frequently, discovering there's no neutral at the switch. Legally it can be DIYable on existing circuits outside bathrooms, but miswired smart modules are a fault we're regularly called to fix — the saving is small and the risk isn't.
How long does a whole-house retrofit take?
Typically 2–4 days for modules, hub and scene programming in an average house — our 12-zone Sevenoaks installation with 70+ new fittings took four days with no re-plastering or redecorating.
