With rising energy bills and a growing focus on sustainability, UK households are increasingly turning to government-backed schemes to improve their home’s energy efficiency. The ECO 4 scheme is one of the most important programmes available today, offering free energy efficiency upgrades to eligible households. But the key to accessing these benefits lies in choosing the right ECO 4 scheme installers.
In this article, we’ll break down everything you need to know about ECO 4 installers—who they are, what they do, how to find a trusted provider, and why working with an accredited installer is essential to getting your home upgraded efficiently and safely.
What Is the ECO 4 Scheme?
The ECO 4 scheme (Energy Company Obligation Phase 4) is a UK government initiative designed to help low-income and fuel-poor households improve the energy efficiency of their homes. Launched in 2022 and running until March 2026, ECO 4 is the latest phase of a long-standing programme that requires large energy suppliers to fund free home energy improvements.
These improvements may include:
-
Free boiler replacements
-
Air source heat pumps
-
Loft insulation
-
Cavity wall insulation
-
Internal or external wall insulation
-
First-time central heating systems
-
Smart heating controls
The ultimate goal is to reduce fuel poverty, cut carbon emissions, and improve the energy performance of UK housing stock—especially for homes with EPC ratings of E, F, or G.
Who Are ECO 4 Scheme Installers?
ECO 4 scheme installers are government-approved professionals or companies authorised to assess properties, apply for funding on behalf of homeowners or tenants, and carry out the installation of energy efficiency measures.
To be eligible to install ECO 4-funded improvements, installers must:
-
Be PAS 2035 or PAS 2030 certified
-
Be registered with TrustMark
-
Work with a registered ECO 4 delivery partner or managing agent
-
Comply with UK government standards for health, safety, and environmental efficiency
Working with an accredited installer ensures the quality, safety, and legal compliance of the work carried out in your home.
What Do ECO 4 Installers Do?
The job of an ECO 4 installer extends beyond just putting insulation in your loft or swapping out a boiler. Here’s what a full-service ECO 4 installer typically provides:
✅ Property Assessment
They’ll evaluate your home’s current energy performance through a free EPC assessment and identify which upgrades will offer the most benefit.
✅ Grant Eligibility Check
Installers check if you qualify for free energy improvements under ECO 4, based on income, benefits received, and property conditions.
✅ Funding Application
They handle the entire grant application process on your behalf, including submission to energy companies or local councils.
✅ Installation of Energy Upgrades
Qualified technicians install energy-saving measures like solid wall insulation, heating systems, or solar panels, depending on your eligibility and home’s needs.
✅ Post-Work Compliance
Once the installation is complete, they provide documentation to prove the work meets PAS 2035 compliance standards—a requirement for grant funding.
