Smart thermostats have taken UK homes by storm, helping reduce energy bills and giving users more control over their heating. But what about small businesses? Are they worth the investment in commercial settings?

In this guide, we’ll explore the pros and cons of installing smart thermostats in offices, shops, and other small business environments — and whether it could make financial and operational sense for you.

What Is a Smart Thermostat?

A smart thermostat is an internet-connected device that allows you to control your heating system remotely, often via an app or smart assistant like Alexa or Google Assistant.

Popular models in the UK include:

  • Hive

  • Nest

  • Tado

  • Drayton Wiser

These thermostats learn your usage patterns, adjust temperatures automatically, and let you monitor energy usage in real-time.

Benefits for Small Businesses

While most marketing focuses on homeowners, smart thermostats can bring real value to small commercial premises. Here’s how:

1. Lower Energy Bills

Heating accounts for a large portion of energy costs, especially in colder months. Smart systems optimise usage, meaning you don’t pay to heat empty premises.

2. Remote Access

Heading home and forgot to turn the heating off? No problem. Control it from your phone. This is ideal for business owners who aren’t always on site.

3. Better Scheduling

Set different temperatures for different times and days — perfect for businesses with variable hours or seasonal opening patterns.

4. Zoning Capabilities

Some systems allow separate control of different rooms or floors, which can reduce waste in unused areas.

What to Consider Before Installing

Smart thermostats aren’t for every setup. Here’s what to weigh up:

  • Existing Heating System – Older systems without modern boiler controls may need upgrades. Southam Electrical can advise on this during installation.

  • Internet Reliability – These systems rely on stable Wi-Fi. If your broadband is patchy, it could limit remote functionality.

  • Initial Cost – Expect to pay £150–£250+ for a unit, plus installation. The long-term savings typically outweigh the upfront expense, but this depends on your current usage.
