Best Smart Heating Controls for UK Flats
Smart heating controls let you heat your flat only when you need it — scheduling by room, warming up before you get home, and turning everything down from your phone when you’re out. For flats, the big question is what you’re allowed to change: a full smart thermostat often needs to replace your boiler controls (and, if you rent, your landlord’s permission), while smart radiator valves clip onto individual radiators and are far more renter-friendly. This guide covers both.
QUICK ANSWER
If you own your flat or have permission, a smart thermostat (like the Hive Mini or a tado° kit) gives you full app control and scheduling. If you rent, smart thermostatic radiator valves (TRVs) such as the tado° or TP-Link Kasa are the better choice — they replace the valve head on each radiator without touching the boiler and can be swapped back when you leave.
Renters, read this first
A smart thermostat usually wires into your boiler or replaces an existing programmer, which typically needs the landlord’s consent and sometimes an installer. Smart radiator valves simply replace the twist head on a radiator — a reversible, tool-light job that suits rented flats. Keep any original parts so you can restore them when you move out, and check your tenancy agreement before changing fixed controls.

The best smart heating controls for flats
Hive Thermostat Mini (combi boilers, hubless)
Best for: Straightforward app-based heating control
Hive is one of the most popular UK smart heating brands, and the Mini gives you app scheduling, geolocation and voice-assistant support for combi-boiler systems without needing a separate hub. It’s a clean, well-supported choice if you can install a thermostat in your flat.
Pros
- Well-known, well-supported UK brand
- App scheduling and geolocation
- Works with common voice assistants
- No separate hub needed for this model
Cons
- Best suited to combi boilers
- A thermostat swap may need landlord permission if you rent
tado° Wireless Smart Thermostat V3+ Starter Kit
Best for: Heating and hot water scheduling in one kit
The tado° starter kit includes the wireless thermostat and the programmer connection you need to get going, with strong app control, geofencing and optional add-ons like smart radiator valves later. A good gateway into a whole tado° system.
Pros
- Complete starter kit for many setups
- Excellent app with geofencing
- Expandable with tado° smart valves
- Heating and hot water control
Cons
- Some features sit behind an optional subscription
- Installation may need permission in a rented flat
Honeywell Home T6 Smart Thermostat
Best for: A polished wired thermostat with strong scheduling
Honeywell Home’s T6 is a mature, reliable smart thermostat with flexible scheduling, geofencing and a clear touch display. As a wired unit it’s a tidy permanent upgrade for a flat you own or have permission to modify.
Pros
- Reliable, established brand
- Flexible scheduling and geofencing
- Clear touchscreen
- Good app support
Cons
- Wired installation (best for owners/with permission)
- Less impulse-friendly than a valve swap
tado° Smart Radiator Thermostat X (smart TRV)
Best for: Per-radiator control without touching the boiler
This smart valve replaces the head on an individual radiator, so you can schedule and control each room from your phone — ideal for renters who can’t alter fixed heating. It’s reversible, so you can refit the original valve head when you move out.
Pros
- Renter-friendly: no boiler work
- Room-by-room scheduling and control
- Reversible for when you move
- Part of the wider tado° ecosystem
Cons
- You may want several (one per radiator)
- Some advanced features need a bridge or subscription
TP-Link Kasa Smart Radiator Valve
Best for: Affordable room-by-room smart control
TP-Link’s Kasa smart radiator valve brings app scheduling and temperature control to individual radiators at a friendlier price. A cost-effective way for renters to add smart control one radiator at a time.
Pros
- More affordable smart valve
- App scheduling per radiator
- Renter-friendly and reversible
- Trusted smart-home brand
Cons
- May need a Kasa/TP-Link hub depending on setup
- Fewer premium features than tado°
How to choose smart heating controls for a flat
- Own or rent? Owners (or renters with permission) can fit a smart thermostat; renters should usually start with smart radiator valves.
- Boiler type: check compatibility with your system (combi, conventional, or electric heating) before buying a thermostat.
- Scheduling and geolocation: the real savings come from heating only when rooms are used and turning down automatically when you leave.
- Zoning: smart valves let you heat the living room in the evening and the bedroom at night, rather than the whole flat at once.
- Ecosystem and voice control: pick a brand that works with the app and voice assistant you already use, and that you can expand later.
- Subscriptions: some brands lock advanced automation behind a paid tier — check what’s included.
Frequently asked questions
Can I fit a smart thermostat in a rented flat?
Sometimes, but a smart thermostat usually replaces or wires into your boiler controls, which typically needs the landlord’s permission and may need an installer. If you rent, smart thermostatic radiator valves are usually the better route because they replace the valve head on a radiator and are reversible.
Do smart radiator valves actually save money?
They can, by letting you heat only the rooms you’re using, only when you’re using them, and turning down automatically when you’re out. Savings depend on your habits and tariff, but room-by-room scheduling avoids heating an empty flat.
Do I need a hub for smart heating controls?
It depends on the product. Some thermostats and valves connect directly over Wi-Fi or Bluetooth, while others need a bridge or hub. Check the listing for your chosen model, especially if you want to control several radiators.
Will these work with electric heating?
Smart thermostats are generally designed for boiler-based central heating. If your flat has electric heaters, a smart plug or a smart electric radiator is usually the better way to add scheduling and app control.
Our recommendation by need
If you can fit a thermostat: the Hive Thermostat Mini for simple app control, or the tado° V3+ kit for heating and hot water. If you rent: start with the tado° Smart Radiator Thermostat X, or the TP-Link Kasa valve on a budget, and add more radiators over time.
