A smart home installer (also known as a home automation specialist or integrator) designs and installs connected technology that allows a home's lighting, heating, security, entertainment and access control systems to be controlled and automated from a single interface - typically a smartphone app, touchscreen panel or voice assistant. Smart home installation is not a regulated profession in the UK but the CEDIA (Custom Electronic Design and Installation Association) is the principal trade body for professional home technology installers. CEDIA members must meet training and quality standards, and CEDIA certification is the key indicator of professional competence in this field.
What they do
- Consult on home automation requirements, budget and platform selection
- Design a whole-home automation scheme including wiring, control infrastructure and user interface
- Install and configure smart lighting systems and dimmer controls
- Install and integrate smart heating and thermostat controls
- Install multi-room audio and whole-home AV distribution
- Install integrated security, CCTV and access control systems
- Install motorised blinds, curtains and electric windows
- Program control systems, scenes and automation schedules
- Provide user training and ongoing remote support
When you need one
A professional smart home installer is most cost-effective during a new build or major renovation, when cabling can be installed before walls are plastered.
Typical costs (UK, 2025)
| System type | Typical cost |
|---|---|
| Basic smart home retrofit (thermostat, lighting, doorbell) | £1,500 - £4,000 |
| Smart lighting system (professionally installed) | £3,000 - £15,000 |
| Multi-room audio (Sonos or equivalent) | £2,000 - £8,000 |
| Control4 or Crestron whole-home system | £15,000 - £100,000+ |
| Motorised blinds (per room) | £500 - £2,500 |
| Home cinema room | £8,000 - £50,000+ |
Smart home costs vary enormously depending on the platform, number of rooms and level of integration. Consumer-grade systems can be self-installed at relatively low cost; professional whole-home systems require significant investment in hardware, cabling and programming. Always define your requirements clearly before requesting quotes.
Qualifications to look for
CEDIA membership is the primary quality indicator for professional smart home and home cinema installers. CEDIA members must demonstrate technical competence through training and certification, and commit to a code of conduct. For high-value home automation projects always use a CEDIA certified integrator. Check membership at cedia.net.
Professional home automation platforms require dealers to hold manufacturer certification - for example Control4 dealers must be a Control4 Certified Showroom, Crestron dealers must hold Crestron certification, and Lutron installers require Lutron HomeWorks training. Platform certification demonstrates that the installer is trained to design and programme the specific system they are installing.
If the smart home installation involves any new electrical circuits - for example, dedicated lighting circuits, in-wall speaker wiring or security system cabling from the consumer unit - this work must be carried out by a Part P registered electrician or notified to Building Control. Confirm that the installer holds or subcontracts the relevant electrical certification.

What smart home platforms are available?
The main consumer smart home platforms are Amazon Alexa, Google Home and Apple HomeKit - these work with thousands of compatible devices from many manufacturers and are controlled via smartphone app and voice. For professional whole-home automation, installers often use dedicated platforms such as Control4, Crestron, Savant, Lutron and KNX. These offer deeper integration and more reliable performance than consumer platforms but require professional installation and programming and are significantly more expensive. For a managed retrofit without rewiring, Philips Hue (lighting), Nest (heating), Ring (doorbell/security) and similar consumer products offer excellent functionality at accessible prices.
Can smart home technology be retrofitted to an existing home?
Yes, most smart home technology can be retrofitted to existing homes without major rewiring. Consumer-grade devices such as smart plugs, smart bulbs, smart thermostats, video doorbells and wireless security cameras can be installed by a competent homeowner with no electrical work required. Wireless protocols such as Zigbee, Z-Wave and Wi-Fi allow complex scenes and automation without running new cables. However, for more sophisticated control of lighting circuits, motorised blinds or integrated multi-room audio, a professional installer will need to carry out some wiring work and this is easier to do during a renovation or new build.
Is smart home technology worth the cost?
Entry-level smart home technology (smart heating, smart lighting and a video doorbell) typically costs £500-2,000 self-installed and delivers tangible energy savings, convenience and security improvements. Professional whole-home automation systems from Control4 or Crestron can cost £20,000-100,000 and appeal to buyers of high-end homes. For most homeowners, a mix of consumer smart devices (smart thermostat, smart lighting, video doorbell) offers good value. The key question is whether you will actively use the features - smart home technology only saves energy and money if it is programmed and used appropriately.
