What's Changed in Smart Home Tech
The smart home market of 2026 is very different from 2019. Products have become more reliable, setups have become simpler, and the major platforms — Google Home, Apple HomeKit, Amazon Alexa and the new Matter standard — now work together more consistently than before. The result is that smart home installations that would have required technical knowledge and constant troubleshooting a few years ago now work out of the box for most people.
The key question is: which products actually make your home more convenient and more efficient, versus which ones just add complexity? Here's our honest assessment.
Definitely Worth It
Smart Thermostat
The highest-ROI smart home purchase available. A Nest or Hive thermostat learns your schedule, can be controlled remotely, and integrates with weather data to heat your home only when needed. UK energy prices have made heating efficiency a financial priority. Most homeowners recover the cost of a smart thermostat within 12-18 months through reduced energy bills. Professional installation takes about an hour and ensures everything is wired correctly.
Smart Doorbell
A Ring or Google Nest doorbell provides a clear view of your entrance, motion alerts and two-way audio — all on your phone whether you're home or not. In London, where parcel theft from doorsteps is common, the deterrent and evidence value is real. Most doorbells are battery-powered and easy to fit without any wiring changes.
Smart Plugs (for specific use cases)
Smart plugs — sockets that can be controlled via app or voice — are inexpensive and genuinely useful for two specific cases: (1) turning off devices you frequently forget to switch off (lamps, heaters, fans), and (2) scheduling appliances like slow cookers and dehumidifiers. Don't buy them in bulk hoping to automate everything — buy them for specific problems you actually have.
Smart Lighting in High-Traffic Areas
Philips Hue and similar systems are genuinely useful in hallways, stairwells and outdoor areas where motion-activated lighting serves a real purpose. Smart bulbs in living areas are more of a nice-to-have. Focus on rooms where automated or voice-controlled lighting actually changes how you use the space.
Worth It With Caveats
Smart Locks
Smart locks — keypad entry, app control, temporary access codes for cleaners or tradespeople — solve real problems for households with variable access needs. They work reliably on most modern doors. The caveat: they require proper installation aligned with your lock mechanism. A poorly fitted smart lock can compromise home security. Get it installed professionally.
Smart Security Cameras
External cameras provide deterrence and evidence value. Internal cameras — be honest with yourself about whether you actually need these versus whether you're buying into anxiety. If you have genuine security concerns, they add value. If you just like the idea, save the money.
Overhyped
Smart fridges and appliances — the connectivity features rarely justify the significant price premium. Smart blinds — useful in very specific circumstances, but expensive and the motors fail more often than mechanical alternatives. Robot vacuums — useful for some homes, but require a clear floor to work and don't replace proper cleaning.
Getting Everything Working Together
The biggest practical challenge with smart home devices is getting them all on the same platform so they work together. Choose one ecosystem — Google Home, Apple HomeKit, or Amazon Alexa — and stick to it. The Matter standard (2023+) is making cross-platform compatibility much better, but single-ecosystem setups are still simpler.
