Smart Home Tech for Rental Properties: What's Worth Installing

Smart home technology can reduce costs, attract better tenants, and protect your property — but not every gadget is worth the investment in a rental context. Here's a practical guide to what works and what doesn't.

Smart thermostats (strong yes)

A smart thermostat (Hive, Nest, tado) costs £150-250 installed and can reduce heating bills by 10-20%. For landlords paying bills (inclusive rents, HMOs, void periods), the savings are direct. For tenants paying their own bills, it's a genuine selling point that justifies slightly higher rent. Smart thermostats also let you remotely set a frost-protection minimum during void periods.

Smart locks and keyless entry (worth considering)

Electronic locks (Yale Conexis, Nuki) eliminate key cutting, lost key hassles, and lock changes between tenancies. You can issue unique access codes per tenant and revoke them remotely. Cost: £150-300 per lock. The ROI comes from saved locksmith calls and faster turnovers. Check your insurance policy — some require a specific lock standard (BS3621).

Leak detectors (strong yes)

A £30 water leak sensor under the kitchen sink or by the washing machine can alert you to leaks before they cause thousands in damage. Smart versions (connected to Wi-Fi) send alerts to your phone. Given that escape of water is the most common landlord insurance claim, this is arguably the highest-ROI smart device you can install.

Smart smoke and CO alarms (yes)

Connected smoke alarms (Nest Protect, FireAngel) send alerts to your phone as well as sounding locally. You'll know immediately if an alarm triggers in your rental property — even if you're miles away. They're more expensive (£80-120 each) but the peace of mind and safety benefit justify it.

Smart plugs and lighting (rarely worth it)

Smart bulbs and plugs add complexity with minimal benefit in a rental. Tenants may not use them, they require app setup, and they break or disappear between tenancies. Unless you're running serviced accommodation, skip these.

CCTV and video doorbells (careful)

Video doorbells (Ring, Google Nest) are popular with tenants for security. But CCTV raises data protection issues — you must comply with GDPR if cameras capture public areas. Install only at the tenant's request, and ensure they control the camera during their tenancy.

Installation tips

• Choose devices that work without the tenant's Wi-Fi where possible
• Ensure any smart device can be factory-reset between tenancies
• Include smart devices in the inventory and tenancy agreement
• Budget for replacements every 5-7 years
