A smart thermostat is a small upgrade that pays off in several ways for a landlord: tenants get easy control and lower bills, you can protect an empty property from freezing between lets, and better heating control nudges your EPC in the right direction. This guide covers what to check before you buy — compatibility matters — and rounds up four well-reviewed smart thermostats that suit UK rentals.

Key takeaways
- Check compatibility first — combi boiler, system boiler, heat pump and electric underfloor all need the right model.
- Remote control lets you protect an empty property from frost between tenancies.
- Better control means lower tenant bills and a marginally better EPC.
- Have it installed by a qualified person; wiring into a boiler isn’t a DIY job.

Why a smart thermostat is worth it in a rental
Three landlord benefits stand out. Void protection: between tenancies you can set a frost-protection temperature remotely, avoiding burst pipes without heating an empty house all winter. Tenant appeal and lower bills: app control and smart scheduling help tenants use less energy, which makes the property more attractive and reduces complaints. Efficiency: better control supports your energy rating and pairs well with modern heating such as an air source heat pump. For a landlord who already manages remotely, remote heating control is a natural fit.
How to choose one for your property
Choosing a smart thermostat, step by step
Combi boiler, system boiler, heat pump or electric underfloor — this decides the model.
Use the maker’s compatibility checker before you buy; not every thermostat suits every system.
Usually the tenant day to day, with you able to set frost protection during voids.
Wiring into a boiler is a job for a qualified heating engineer or electrician.
The most common setup in UK rentals is a combi boiler, which the Hive and tado° models are designed for; electric underfloor needs a dedicated thermostat like the Meross. When in doubt, run the manufacturer’s compatibility checker before ordering.

FAQ
Will a smart thermostat lower my tenants’ bills?
It can, through better scheduling and app control that avoids heating an empty home. Savings depend on how it’s used, but the control usually helps.
Can I control the heating remotely between tenancies?
Yes — that’s a real landlord benefit. You can set a low frost-protection temperature during a void to prevent frozen pipes without heating the property fully.
Do smart thermostats work with any boiler?
No — check compatibility first. Combi, system, heat pump and electric underfloor systems need the right model, so use the manufacturer’s compatibility checker before buying.
Who should install it?
A qualified heating engineer or electrician. Wiring a thermostat into a boiler is not a DIY job, and getting it wrong can affect safety and any warranty.
