With energy prices continuing to rise, many UK households are turning to smart technology to improve energy efficiency and save on bills. But if you're wondering “Does ECO4 cover smart heating controls and thermostats?”—the answer is yes, in many cases.
In this blog, we break down how the ECO4 scheme supports smart heating upgrades, what systems are eligible, and how you can apply for funding.
What is the ECO4 Scheme?
The Energy Company Obligation Phase 4 (ECO4) is a UK government-backed programme aimed at reducing fuel poverty and cutting carbon emissions. It provides funding to improve the energy efficiency of homes, especially for low-income and vulnerable households.
Upgrades available through ECO4 include:
- Insulation (loft, cavity wall, underfloor)
- Renewable heating systems (like air source heat pumps)
- Smart heating controls and thermostats
- Electric storage heater upgrades
- Solar PV systems
Does ECO4 Include Smart Heating Controls and Thermostats?
Yes, the ECO4 scheme can include smart heating controls as part of a wider retrofit package. These controls are often installed alongside new heating systems or as part of a complete energy efficiency upgrade.
Smart controls can help regulate your heating more effectively, reduce energy waste, and lower your bills—all of which align with ECO4’s goals.
What Are Smart Heating Controls?
Smart heating controls allow you to:
- Set heating schedules remotely (via an app or smart device)
- Adjust room-by-room temperatures (zonal control)
- Monitor your energy usage in real-time
- Learn your habits and adjust heating automatically
Common types include smart thermostats (like Nest or Hive), smart TRVs (thermostatic radiator valves), and full smart heating systems integrated with home automation.
Who Is Eligible for Smart Heating Controls Under ECO4?
You may qualify for ECO4-funded smart heating upgrades if:
- You’re receiving qualifying benefits (e.g. Universal Credit, Housing Benefit, Child Tax Credit, etc.)
- Your home has a low Energy Performance Certificate (EPC) rating of D, E, F or G
- You qualify under your council’s LA Flex scheme
- Your existing heating system is inefficient or outdated
Typically, smart controls are offered in combination with other energy improvements such as new heating systems, insulation, or renewables—not usually as a standalone upgrade.
How to Apply for ECO4 Smart Heating Upgrades
Follow these steps:
- Check if you’re eligible – Most ECO4 providers offer a free online eligibility checker.
- Get a Retrofit Assessment – A qualified assessor will evaluate your property and suggest improvements, including smart heating controls if applicable.
- Approve the Retrofit Plan – You’ll receive a tailored plan outlining all recommended works.
- Installation – A TrustMark-registered installer will carry out the upgrades, often free or heavily subsidised.
Why Smart Controls Matter
- Save up to £150–£300 per year on your heating bills
- Reduce unnecessary energy usage
- Improve comfort and convenience
- Support the UK’s net zero carbon goals
Final Thoughts
If you're eligible for the ECO4 scheme, smart heating controls and thermostats can be part of your home energy upgrade. While they’re not always installed on their own, they’re often included when replacing an inefficient heating system—helping you take full control of your home’s warmth and energy usage.
Key Takeaways:
- ECO4 can cover smart thermostats and heating controls as part of a full retrofit.
- These upgrades help improve energy efficiency and cut heating bills.
- Eligibility depends on income, benefits, and your home’s energy rating.
- A retrofit assessment is the first step to unlock support.
