Google Nest in 2025: What UK Homeowners Need to Know

As smart home technology continues to evolve in 2025, Google Nest remains at the forefront of intelligent home heating and security. For UK homeowners and engineers, staying updated on the latest Nest developments is crucial — not just for convenience, but for ensuring systems remain compatible and efficient.

Here’s what’s changing with Google Nest this year, and how it might affect your heating setup.

🏡 The Move to Google Home App

One of the biggest updates is Google’s full transition of Nest devices into the Google Home app. If you’ve been using the Nest app to control your thermostat or monitor smoke alarms, this shift means you’ll soon be managing everything under one unified platform — Google Home.

What's new:

Nest Protect (Smoke + CO alarm) is now supported in the Google Home app.

Users can access alerts, safety check-ups, and emergency calling features (with Nest Aware).

The Nest app is being phased out for new devices.

🔧 Tip from Heating-Parts.co.uk: If you stock or install Nest products, it’s time to get comfortable with the Google Home app and help your customers make the switch smoothly.

❌ Farewell to Legacy Nest Products

Google has discontinued two major products in 2025:

Nest Protect Smoke Alarm (Gen 2)

Nest x Yale Smart Lock

While existing units will continue to work and receive updates, no new versions are being manufactured. Google and Yale have confirmed a new Matter-compatible smart lock is in the works — designed to work seamlessly with Nest doorbells and the Google Home ecosystem.

📉 Feature Removal: Sound Detection on Google Home Max

From May 8, 2025, Google will remove the sound detection feature from Home Max speakers. If you’ve relied on this to detect sounds like glass breaking or smoke alarms, you’ll need a compatible Nest device paired with a Nest Aware subscription to retain that level of security.

🌡️ The 4th-Gen Nest Learning Thermostat is Here

Perhaps the most exciting update for heating enthusiasts — Google has dropped a brand-new Nest Learning Thermostat (4th Generation):

Sleek, modern design with customizable display

Wider compatibility with UK HVAC systems

Matter-certified (yes, it works with Alexa and Apple Home too)

Enhanced sensors and learning capabilities

🧠 Heating-Parts Insight: This new thermostat integrates only with the Google Home app, not the old Nest app — something installers and homeowners should be aware of before upgrading.

🔮 Looking Ahead: More Devices, Smarter Homes

Despite retiring a few classics, Google is far from done. New Nest-compatible devices are in development, and Matter integration will allow broader compatibility across platforms — giving UK homeowners more flexibility and control than ever.

Why This Matters for Heating Engineers & Smart Home Enthusiasts

As homes get smarter, your heating system should too. Whether you're installing a Nest Thermostat, replacing a heat link, or integrating it with underfloor heating — knowing what's current (and what’s being discontinued) is essential.
