What does a smart home cost in the UK?
The cost of a smart home in the UK varies enormously depending on the number of rooms, device types, and brands you choose. A single-room starter setup with a smart speaker and a couple of bulbs might cost as little as £30–£50, while a fully-automated multi-room home with cameras, sensors, and voice control can easily run to £500–£1,500+.
The calculator above gives you a realistic estimate based on actual UK retail prices as of 2025. All product links use the Amazon UK affiliate tag filce-21 and help support this site at no extra cost to you.
