ECO 4 Scheme Installers: Find Accredited Experts for Free Energy Upgrades

With rising energy prices and growing concerns about carbon emissions, improving your home's energy efficiency has never been more important. Fortunately, the UK government is helping homeowners and tenants do just that through the ECO 4 scheme—a government-backed initiative that provides free home energy upgrades for eligible households.

But to benefit from this funding, you must work with ECO 4 scheme installers. These professionals are licensed and trained to deliver energy-efficient improvements to your home—completely free of charge if you meet the criteria.

This article explains how the ECO 4 scheme works, how to find trusted ECO 4 installers in the UK, and how to access free insulation, heating upgrades, or even a new boiler or heat pump through the scheme.

What Is the ECO 4 Scheme?

The ECO 4 scheme (Energy Company Obligation Phase 4) is the latest phase of a government initiative requiring large energy companies to fund energy-saving improvements in UK homes.

Running from 2022 to 2026, the scheme is designed to support low-income and vulnerable households living in poorly insulated or hard-to-heat homes. The aim is to reduce fuel poverty, cut carbon emissions, and improve overall energy efficiency.

Key Improvements Available Under the ECO 4 Scheme:

• Loft insulation

• Cavity wall insulation

• Internal wall insulation

• External wall insulation

• Floor insulation

• Air source heat pumps

• Boiler replacements (non-condensing models only)

• First-time central heating

• Solar panels (in some regions)

All these improvements must be carried out by ECO 4 accredited installers to ensure quality, compliance, and access to grant funding.

Who Is Eligible for the ECO 4 Scheme?

The ECO 4 scheme targets households that are struggling with high energy bills, poor energy efficiency, or low incomes. You may be eligible if:

• You receive government benefits (e.g., Universal Credit, Pension Credit, Income Support, Housing Benefit, ESA, JSA, Child Tax Credit, or Working Tax Credit)

• Your total household income is below £31,000 per year

• Your home has an EPC rating of D, E, F, or G

• You live in a fuel-poor or hard-to-heat property

• You qualify under LA Flex (Local Authority Flexible Eligibility)

Even if you don’t receive benefits, local councils may still approve you under LA Flex if your home is inefficient or someone in your household is vulnerable to cold.

Why You Must Use ECO 4 Accredited Installers

In order to receive any funding through the ECO 4 scheme, you must use a certified installer who is:

• TrustMark registered

• Compliant with PAS 2030 and PAS 2035 standards

• Experienced in delivering whole-house retrofit services

• Authorised to work under the ECO 4 framework

These ECO 4 grant providers manage the entire process—from eligibility checks and surveys to installation and follow-up. Working with a reputable installer ensures that your upgrades are:

✅ Safe
✅ Energy-efficient
✅ Fully compliant with UK building regulations
✅ Delivered with no upfront cost (if you're eligible)

How to Find ECO 4 Installers in the UK

Looking for ECO 4 installers near you? Here's how to find a qualified provider:

???? 1. Search the TrustMark Directory

TrustMark is the official government-endorsed register for approved tradespeople. You can search by postcode to find ECO 4 registered installers in your area.

???? 2. Use an ECO Grant Application Portal

Many online portals allow you to check eligibility, request a callback, and get connected with local ECO 4 scheme installers. These sites work with vetted and approved providers.

???? 3. Contact Your Energy Supplier

Some large utility companies like British Gas or E.ON work directly with ECO 4 partners and can arrange free surveys and installations.

???? 4. Check Local Council or Housing Authority Schemes

Your local authority may have a list of approved ECO 4 contractors working under LA Flex in your area.

What Services Do ECO 4 Scheme Installers Provide?

ECO 4 installers are equipped to deliver a whole-house approach to energy efficiency. This means they don’t just install one improvement—they assess your home and recommend multiple upgrades for maximum impact.

Common Services Include:

• Home energy assessments (including EPC checks)

• Insulation upgrades (loft, wall, floor, room-in-roof)

• Heating system upgrades (heat pumps, boilers, smart controls)

• Renewable energy installs (solar panels)

• Ventilation and air quality improvements

They handle everything—from the initial survey and paperwork to final installation and inspection.

Step-by-Step: What to Expect from ECO 4 Installers

Here’s how the typical process works:

✅ Step 1: Pre-Qualification Check

Submit a few details online or by phone to check if your home qualifies for ECO 4 funding.

✅ Step 2: Free Home Survey

An assessor visits your property to conduct an energy performance assessment and determine which improvements are needed.

✅ Step 3: Application Submission

The installer manages your grant application and submits it to the relevant funding body or energy company.

✅ Step 4: Installation

A qualified team completes the work—often within a few days—depending on what’s being installed.

✅ Step 5: Post-Installation Report

Your installer provides an updated EPC certificate and ensures that the home meets all compliance and safety standards.

Benefits of Working With ECO 4 Installers

✅ No upfront costs – Fully funded if you meet the criteria
✅ Expert advice – Tailored energy efficiency recommendations
✅ Safe and compliant – Work delivered to the latest UK retrofit standards
✅ End-to-end support – From application to installation
✅ Long-term savings – Lower energy bills, warmer home, and higher property value

Red Flags to Avoid

While most installers are genuine, always be cautious of:

???? Installers who ask for upfront fees
???? Companies not registered with TrustMark or lacking ECO 4 accreditation
???? Firms that avoid giving clear information about the process or eligibility

Always check reviews, accreditations, and credentials before agreeing to any work.
