The short answer
Smart home installation in the UK typically ranges from around £1,500 for a basic setup to £20,000+ for a fully integrated system, with a common mid-range whole-home install landing around £5,000–£15,000 once lighting, heating and a few other functions are covered. Professional fitting usually adds roughly £200–£500 per room on top of the hardware, depending on size and complexity. At the top end, large bespoke wired systems from the likes of Control4, Loxone or KNX can run well into tens of thousands of pounds. The main drivers are how many rooms and functions you automate, whether the system is wireless or hardwired, and your property's size and age.
Price depends mainly on how ambitious you are — a few plug-in devices is a different job to wiring a whole house. The figures below are typical installed ranges for guidance, not quotations.

What drives the price
- Rooms & functions: you largely pay per room and per function, so lighting plus heating plus blinds across a whole house costs far more than a single smart speaker and a few bulbs.
- Wireless vs wired: off-the-shelf wireless kit (smart bulbs, plugs, a hub) is the lowest-priced route; a hardwired system installed in the fabric of the house costs more but is more reliable.
- Property size & age: a larger or older home needs more devices and, for wired systems, more cabling and labour.
- Electrical works: if new circuits or consumer-unit changes are needed, a registered electrician's time and certification add to the figure.

Why the range is so wide
A smart home is not one product but a stack of choices. At one end, you can spend a few hundred pounds on plug-in devices and set them up yourself; at the other, a bespoke wired system that controls lighting, heating, blinds, audio and security across a large house can run into tens of thousands of pounds. Most homeowners sit somewhere in the middle, which is why the typical figure spans £5,000–£15,000. Building up in stages — starting with the functions you value most — is a common way to spread the cost.
