Smart Lighting in 2026 — Systems, Costs and What to Actually Buy
Smart lighting ranges from a £10 bulb to a five-figure wired system. Here's how the tiers really compare — and which one fits your home.
The three tiers of smart lighting
Almost every smart lighting setup falls into one of three tiers, and picking the right tier matters more than picking the right brand.
- Smart bulbs — replace the lamp itself (from ~£10/bulb). Quick and renter-friendly, but the wall switch becomes the enemy: switch it off and the 'smart' bulb is just off
- Smart switches and modules — replace the switch, or hide a relay module behind the existing one. The whole circuit becomes controllable, physical switches keep working, and any fitting can be used. This is the sweet spot for most homes
- Wired control systems — dedicated lighting control (Lutron, Rako and similar) cabled through the house. Superb, and priced accordingly — realistic budgets start around £4,000–£5,000 and climb steeply. Best specified during a rewire or major renovation
Why we usually recommend the switch/module tier
Retrofit smart modules sit behind your existing switch plates, so the house looks unchanged and every switch still works the way guests expect — but every zone gains app control, scheduling, dimming and voice control. There's no reliance on individual bulbs, so you can use any fitting you like, including the cheap ones.
It's also the tier that scales sensibly: start with the kitchen and living room, add bedrooms later, and the system grows zone by zone without rework. A typical whole-house installation across 10–12 zones lands in the £1,500–£3,500 range including modules, hub and installation — a fraction of a fully wired system, with most of the everyday benefit.
One caveat: many smart modules need a neutral wire at the switch, which some older UK lighting circuits don't have. No-neutral modules exist, but this is exactly the kind of thing to survey before buying hardware — we check it in minutes.
Features worth paying for (and skipping)
Worth paying for: proper dimming (smooth, flicker-free, matched to your LEDs), scenes ('Cooking', 'Movie', 'All off'), schedules that follow sunset, and open standards — Matter and Thread support means your system won't be orphaned when one app shuts down.
Usually skippable: colour-changing everywhere (great in one or two rooms, gimmicky in twelve), per-bulb control in rooms that always switch together, and closed ecosystems that lock every future purchase to one brand.
Getting it installed
Smart bulbs are DIY. Switch and module installations involve mains wiring at the switch — and dimming compatibility, neutral availability and load limits are exactly where amateur installs go wrong. An electrician also certifies any circuit alterations, keeping your paperwork clean.
We design and install smart lighting across London and Kent — from a single dimming circuit to whole-house schemes like our recent Sevenoaks project. See our lighting installation service or call 07535 810812.
Frequently Asked Questions
Do smart bulbs or smart switches work better?
For whole rooms and whole houses, smart switches or modules win: the switch keeps working, any bulb can be used, and control is per-zone rather than per-bulb. Smart bulbs shine for renters, lamps, and colour effects in a single room.
Will smart lighting work if my internet goes down?
Good systems keep working locally — wall switches always work, and hub-based systems (Zigbee/Thread) keep schedules and scenes running without the cloud. Cheap WiFi-only bulbs are the most internet-dependent, which is another reason we steer clients toward hub-based setups.
Can smart lighting cut my energy bills?
Modestly, yes — LEDs are already efficient, but dimming, scheduling, and lights that turn themselves off do trim waste. The bigger everyday wins are comfort, security (presence simulation while you're away) and not arguing about who left the landing light on.
