Best Smart Radiator Valves for UK Flats
In a flat, you rarely need every radiator on at once — yet a standard heating system heats the whole place the same. A smart radiator valve (a smart TRV) fixes that by letting you control each radiator, or group of radiators, from your phone: schedule the bedroom to warm before you wake, drop the spare room to frost-protection, and only pay to heat the rooms you use.
Most smart TRVs replace just the valve head, which usually screws off and on without tools — so they suit renters, and can be swapped back when you move. A few need a small hub to connect.
QUICK ANSWER
Smart radiator valves let you control individual radiators or rooms from your phone, so you only heat the rooms you use and can schedule them. Most replace the existing valve head tool-free, making them renter-friendly; some need a hub.

How we chose
We looked at compatibility with common UK valve bodies, whether a hub is required, app scheduling and zoning, battery life, and how easily the system can be removed and the original valves reinstated at the end of a tenancy. We describe published specifications and manufacturer information rather than quoting prices or star ratings, which change — check the current figures on Amazon before buying.

Common questions
Do smart radiator valves save money?
They can, by letting you heat only the rooms you use and schedule them around your day rather than warming the whole flat. Actual savings depend on your habits and setup.
Can renters fit smart radiator valves?
Usually yes. Most replace only the valve head, which screws off and on by hand, so there is no plumbing and you can refit the original when you move out.
Do I need a hub?
Some systems (like Hive and Wiser) use a small hub for full scheduling and remote control; others connect over Wi-Fi. Check before buying.
Will they fit my radiators?
Most fit the standard UK valve size and include adapters for common types. Check your valve body against the product’s compatibility list.
Our recommendation
For flexible, expandable control, the Drayton Wiser smart TRV is our overall pick. Already using Hive? Its valve fits neatly. On a budget, the TP-Link Kasa gives app scheduling for less.
