Smart home devices are everywhere—smart thermostats, smart plugs, automated lighting, sensors, and smart home assistants. They promise cheaper bills, comfort, and energy-saving living. But the question UK households want answered is: is smart home technology a true money-saving solution or just hype?
Here's a simple, practical, and SEO-friendly breakdown of what does and doesn't save money for UK readers.
What Is Smart Home Technology?
Smart home technologies encompass devices such as:
- Smart thermostats (Hive, Nest, Tado)
- Smart plugs
- Smart lighting
- Smart meters
- Voice assistants
- Smart appliances
Their purpose: They're trying to waste less, be more comfortable, and provide you with total control over the energy expenditure in your home.
Does Smart Home Tech Really Save Money?
Short Answer: YES – When Used The Right Way
The optimal combination of devices and habits can save UK households £120-£300 per year

Smart plugs help you:
3. Smart Lighting – Long-term Savings

4. Smart Meters = Knowledge = Savings
Smart meters don't directly save money—however, they help you understand which devices are most expensive to use, so you can reduce usage.
💡 Real-time feedback helps households make smarter energy choices throughout the day.
5. Smart Home Security – Indirect Financial Benefits
Smart doorbells, cameras, and motion sensors help minimize theft and can reduce insurance payments.
6. Smart Appliances – Not Mega Savings but Still Necessary
They issue warnings, run during off-peak times, and have eco modes.
Plus massive convenience benefits
7. Smart Electricity Tariffs: The Money Saver You Don't See
When used together with smart electricity tariffs, smart home technology becomes even more powerful.
Smart peak/off-peak pricing, where electricity becomes cheaper (or even free) at certain times, is already available at many UK energy providers.
Smart devices can be used to automatically turn on the washing machine, dishwasher, dryer, and EV charger at times when electricity costs less. It's at this point that savings can increase significantly.

EDF periodically launches smart rewards, such as:

💡 Pro Tip:
When you run your washing machine, dishwasher, and charge items during these free or cheaper hours, the savings add up very fast.
