How Much Does a Smart Home Installation Cost in London? (2026 Guide)

The most common question we get: "How much will this cost?" The honest answer is that it depends on your property, what you want, and whether it's a new build or retrofit. But here are real numbers from our recent London installations to give you a realistic picture.

Starter: £8,000 - £15,000

At this level you're looking at lighting automation for key rooms, basic climate control, and a security system. Typically covers a 2-3 bedroom flat. You get a Loxone Miniserver, Touch Pure controls in main rooms, and an Ajax alarm system with motion and door sensors. This is enough to make a genuine difference to how you live — automated lighting scenes, heating that follows your schedule, and proper wireless security.

Mid-Range: £15,000 - £40,000

This is where most of our London projects sit. Full lighting automation throughout, climate control with weather-aware shading, multi-room audio in 4-6 zones, comprehensive CCTV, and a full Ajax security system with professional monitoring. Typically covers a 3-5 bedroom house. At this level, your home genuinely runs itself — you'll rarely touch a switch.

Premium: £40,000 - £100,000+

For larger properties or those wanting everything: full Loxone automation, biometric access control, 4K CCTV coverage with AI analytics, enterprise networking with Ubiquiti, multi-room audio throughout, automated blinds and curtains, energy management with solar integration, and EV charger installation. This is the complete smart home experience.

What Affects the Price?

The biggest cost factors are: property size (more rooms = more devices), new build vs retrofit (new builds are cheaper because we can wire during construction), the number of automated systems you want, and the quality of finish (flush-mounted vs surface-mounted). Retrofits typically cost 20-30% more than new builds because of the additional cabling work.

How to Avoid Inflated Quotes

Some installers quote based on what they want to sell, not what you need. Our approach is different: we start with how you actually live, identify the systems that will make the biggest difference, and build from there. Every proposal includes a detailed breakdown with no hidden costs. We'd rather install a smaller system that you love than an expensive one that overwhelms you.
