Smart home installation in Bath
Prices are valid for 2026 and are indicative
Here you can see what smart home installation in Bath costs on average. We explain what the price consists of and which local factors have the biggest impact.
A basic smart home setup (smart thermostat, smart lighting in key rooms, and a smart doorbell) costs £500–£2,000 including installation. A mid-range system with whole-home lighting control, security, and multi-room audio runs £3,000–£8,000. Professional KNX or proprietary smart home systems for new builds or full retrofits can reach £15,000–£50,000+.
UK smart home technology is predominantly wireless (Zigbee, Z-Wave, Thread, or proprietary RF), making retrofit easier without extensive rewiring. Wired systems (KNX) are better suited to new builds or major renovations.

Cost factors
Smart home installation costs in the UK by system scope. Prices include equipment supply and professional installation.
- Smart thermostat (Hive, Nest, tado): £150–£350 installed
- Smart lighting (per room, Philips Hue or similar): £200–£600 per room
- Smart security (doorbell, cameras, alarm): £500–£2,500
- Whole-home smart system (mid-range, wireless): £3,000–£8,000
- Professional KNX or Control4 system: £8,000–£30,000+
- Annual maintenance and monitoring: £200–£1,000 per year
Smart heating controls typically pay back in 2–3 years through energy savings. Other smart home features are lifestyle improvements rather than energy investments.
Why do prices vary?
- System type: DIY wireless systems (Philips Hue, Sonos, Hive) are affordable and flexible. Professional wired systems (KNX, Lutron) are more reliable and feature-rich but much more expensive.
- Retrofit vs new build: Wireless smart home technology makes retrofit much easier — no rewiring needed in most cases. New builds can integrate wired systems from the start, with much lower labour cost.
- Ecosystem choice: Most UK smart homes are based on Apple HomeKit, Google Home, or Amazon Alexa ecosystems. Choosing one ecosystem and sticking to it avoids compatibility issues.
- Integration complexity: Multi-system integration (heating + lighting + security + audio) requires a capable hub and professional programming, especially for scenes and automations.
- Broadband and Wi-Fi infrastructure: A reliable mesh Wi-Fi network is the foundation of a smart home. A poor network degrades all connected devices. Allow £300–£600 for a quality whole-home mesh system if needed.
Subsidies & incentives
No specific UK government grant exists for smart home installation. However, smart heating controls may qualify for 0% VAT if classified as part of a qualifying energy-saving installation. Smart EV chargers benefit from the 5% reduced VAT rate for domestic installation. Smart home systems that optimise energy use (solar, battery, heat pump integration) are not directly subsidised but contribute to the overall return on investment of those systems. No VAT reduction applies to general smart home automation.
