Smart thermostats and heating controls
A smart thermostat lets you set heating times from your phone. It can learn when you are in and out. This may cut wasted heat, because the heating runs only when you need it.
Check that the thermostat works with your boiler. Ask an installer if you are unsure. Results vary by home, so do not expect big savings.
Smart TRVs (thermostatic radiator valves)
Smart TRVs let you control each radiator by room. You can set different temperatures for each space. They suit homes with rooms you rarely use.
They need batteries and a hub. Check compatibility with your system, since not every radiator valve fits. A heating engineer can advise.
Smart water monitors
A water monitor tracks how much water you use. Some clip onto the supply pipe. They can alert you to unusual use, which may signal a leak.
They give useful facts, yet they do not fix a leak. Check how the data is shown and who can see it. Our guide on how to read a water meter shows a free way to start.
Smart water meters
Some water companies fit smart meters that send readings automatically. This helps you spot leaks and track your use. Ask your own water company what it offers, because plans differ.
You do not need to buy this yourself. It comes from the supplier.
Simple smart leak detectors
A leak detector sits on the floor near a boiler or under a sink. It sounds an alarm when it senses water. Some send an alert to your phone.
These are cheap and easy to fit. They give early warning, because they spot the first drops. Place them where leaks are likely.
What’s not worth it
Be careful with gadgets that promise too much. Devices with no clear test results may disappoint. A fancy product does not replace good maintenance.
Check reviews and ask for independent evidence. If a price seems high for what it does, compare other options.
The practical recommendation for most UK homeowners
Start with the basics. Know where your stopcock is and keep drains clear. Then add a leak detector in the places that matter most.
A smart thermostat can follow if you want more control. Choose tools that solve a real problem, since each gadget adds cost.
