With rising energy bills and increasing awareness around climate change, the UK government’s ECO 4 scheme has become a vital lifeline for low-income households. Offering free or heavily subsidised energy-saving improvements, this scheme relies on qualified, certified ECO 4 scheme installers to deliver everything from boiler replacements to insulation and heat pumps.

If you're searching for approved ECO 4 installers or wondering how to choose the right one, you're in the right place. In this guide, we'll break down what the ECO 4 scheme offers, how installers operate, and what to look for when selecting a registered ECO installer near you.

What is the ECO 4 Scheme?

ECO 4 (Energy Company Obligation phase 4) is the latest stage of the government’s long-running energy efficiency programme. Running from 2022 to 2026, ECO4 is aimed at improving the least energy-efficient homes across the UK, especially for low-income households and those in fuel poverty.

Under the scheme, eligible households can receive free energy-efficient upgrades, including:

• First-time central heating systems

• Air source heat pumps

• Loft, cavity wall, and external wall insulation

• Solar panels

• Boiler replacements or upgrades

• Smart heating controls

These upgrades are delivered through certified ECO 4 installers, who assess your property, secure funding on your behalf, and carry out the improvements to PAS standards.

What Do ECO 4 Scheme Installers Do?

ECO 4 installers are accredited energy efficiency experts who are approved to carry out upgrades funded under the ECO scheme. Their job includes:

✅ Verifying your eligibility
✅ Conducting a full home energy assessment
✅ Designing a tailored retrofit plan
✅ Submitting funding applications
✅ Installing energy-saving measures
✅ Ensuring work complies with PAS 2035/2030 standards
✅ Providing post-installation checks and EPC updates

Their expertise ensures that all work is carried out safely, efficiently, and in line with government requirements.

Who Can Benefit from ECO 4 Scheme Installations?

To qualify for ECO 4, your household must meet one or more of the following criteria:

• You own or privately rent your home

• Your property has an EPC rating of D to G

• You or someone in your household receives qualifying benefits, such as:

  • Universal Credit

  • Income Support

  • Pension Credit

  • Housing Benefit

  • Child Tax Credit

  • Jobseeker’s Allowance

  • Employment and Support Allowance

  • Working Tax Credit

  • Personal Independence Payment (PIP)

  • Carer’s Allowance

Even if you don’t receive benefits, you might still qualify via LA Flex, a local council-led pathway that approves households based on income, vulnerability, or health conditions.

How to Find Approved ECO 4 Scheme Installers

Finding a trusted installer is crucial for receiving funding and having quality work carried out. Here’s how to find the right ECO 4-approved installer in your area:

✅ Check for TrustMark Accreditation

All ECO 4 installers must be TrustMark registered and PAS 2030 certified. This ensures that:

• They meet high-quality standards

• Their work is guaranteed

• They are regularly assessed

You can use the TrustMark website to search for accredited installers near you.

✅ Use Government-Recognised Directories

Websites like:

• Ofgem's ECO installer list

• Simple Energy Advice (SEA)

• Local council websites

…are great places to start your search.

✅ Ask These Questions:

Before choosing an installer, ask:

• Are you PAS 2030 and TrustMark certified?

• What types of upgrades do you specialise in?

• Do you handle the grant application process?

• How long will the installation take?

• What guarantees or aftercare do you provide?

Benefits of Choosing a Certified ECO 4 Installer

Partnering with a professional, government-approved installer comes with many advantages:

• 🔒 Peace of mind – Work is quality assured and compliant with regulations

• 💰 No upfront costs – Certified installers apply for funding on your behalf

• 🧱 Tailored solutions – Your home is assessed individually for the most effective improvements

• 🛠️ One-stop service – From surveys to installation to follow-up, all handled by your installer

• 📃 Guaranteed upgrades – Many offer warranties on installations

What Upgrades Can ECO 4 Installers Provide?

Depending on your home and energy needs, certified ECO 4 installers can carry out the following improvements:

🔥 Heating Upgrades

• First-time central heating

• Air source heat pumps

• Boiler replacements (non-condensing to condensing)

• Smart thermostats and controls

🧱 Insulation

• Loft insulation

• Cavity wall insulation

• External wall insulation

• Internal wall insulation

• Underfloor insulation

☀️ Renewable Energy

• Solar PV panels

• Battery storage systems (in some cases)

These measures can help reduce your heating bills by up to £1,500 per year depending on the upgrades and current efficiency levels.

ECO 4 Installers for Landlords and Tenants

Private landlords can also benefit from ECO 4 upgrades—especially in older or poorly insulated rental properties. If the tenant is eligible, the landlord can grant permission for upgrades and improve their property’s energy rating.

This is especially important for meeting the Minimum Energy Efficiency Standards (MEES) and avoiding future fines or restrictions on letting properties rated below EPC E.

Installers can help landlords:

• Navigate grant eligibility

• Ensure minimal disruption to tenants

• Provide post-installation EPC updates

Real-Life Example: How ECO 4 Installers Helped a Low-Income Family

Sarah, a single mum in Leeds, was struggling with heating bills and a failing gas boiler. After applying for ECO 4 support, an approved installer visited her home for a free survey. Within weeks, Sarah received a new A-rated boiler, loft insulation, and heating controls—all installed at no cost. Her home is now warmer, and she’s saving around £900 per year on bills.
