Guide to ECO Plus (Great British Insulation Scheme)

A Simple Introduction

The ECO Plus Scheme, sometimes called the Great British Insulation Scheme, is a government initiative designed to help households reduce heat loss, cut bills, and live more comfortably. It focuses on insulation measures in homes that need them most, making a difference for families who face high energy costs.

At its heart, the scheme is about creating lasting improvements rather than quick fixes. When insulation is installed properly, homes stay warmer in winter, cooler in summer, and require less energy overall. For households across the UK, that means lower bills and a healthier living space.

Why the Scheme Was Launched

Energy prices have been unpredictable in recent years, leaving many people struggling to keep up with costs. The government recognised that a big part of the problem lies with Britain’s housing stock, much of which is poorly insulated, meaning heat escapes quickly.

That’s where ECO Plus comes in. Backed by around £1 billion of funding, the scheme builds on earlier Energy Company Obligation programmes. While ECO4 continues to focus on whole-home retrofits for the most vulnerable households, ECO Plus broadens access. It prioritises homes in lower Council Tax bands and with Energy Performance Certificate (EPC) ratings of D to G.

According to the Energy Saving Trust, households could save an average of £310–£400 each year with the right upgrades. For many families, that’s the difference between manageable bills and financial strain.

For more details on how it operates, Ofgem provides official guidance on ECO Plus.

The Main Advantages of ECO Plus

Joining the ECO Plus Scheme can provide benefits far beyond cheaper energy bills. Here are some of the key ones:

• Financial relief – Upgraded insulation cuts energy waste, which reduces heating costs straight away.
• Year-round comfort – Homes stay warmer in winter and cooler in summer, with fewer draughts or cold corners.
• Healthier living spaces – Good insulation can reduce condensation and mould, both of which affect health.
• Smaller carbon footprint – Using less energy means lower emissions, helping the UK move towards net zero.
• Stronger EPC ratings – A better energy rating can increase property value and make a home more attractive to buyers or renters.
• Energy security – Improved efficiency makes households less vulnerable to fluctuating gas and electricity prices.

It’s worth noting that while the scheme can deliver these benefits, the outcome depends on each property’s condition and the type of measures installed.

Who Qualifies: ECO Plus Eligibility Criteria UK

Checking the ECO Plus eligibility criteria UK is the first step before applying. The scheme mainly supports:

• Households on means-tested benefits such as Universal Credit, Income Support, or Pension Credit Guarantee Credit.
• Homes with lower EPC ratings (D, E, F or G), where insulation upgrades will make the biggest difference.
• Families on modest incomes who may not receive benefits but still struggle with high energy bills.
• Main residences – the property generally needs to be lived in by the applicant or household member.

The scheme uses Council Tax banding as an extra filter in England, which means homes in bands A to D, and in Scotland and Wales, bands A to E.

For the latest official rules, Ofgem’s ECO Plus page has detailed guidance.

Everyday Examples of Who May Qualify

To make this clearer, here are a few scenarios:

• A retired couple living in a 1960s bungalow with an EPC rating of F may qualify because their home loses heat quickly.
• A working single parent in a Band C semi-detached house may be eligible if they receive Universal Credit.
• A young family in a Band D property, not on benefits but with a combined income below the set threshold, could also access support.

In each case, eligibility depends on household details, property performance, and local delivery of the scheme.

How So Eco Fits In

Beyond ECO Plus: Other Options to Explore

While ECO Plus focuses on insulation, there are other ways to improve a home’s efficiency. At So Eco, we also help homeowners explore:

• Solar panels – Generate your own electricity from sunlight.
• Solar batteries – Store spare energy for later use, reducing reliance on the grid.
• Heat pumps – An efficient alternative to boilers, often supported by the Boiler Upgrade Scheme.
• Insulation upgrades – From loft insulation to internal wall and room-in-roof insulation.

You can see what support you might be entitled to in minutes using our eligibility checker.

Challenges and Limitations to Be Aware Of

It’s important to be realistic about the ECO Plus Scheme:

• Funding levels vary – Some households will receive full coverage, others may need to contribute.
• Installer availability – In certain areas, there may be waiting times if demand is high.
• EPC assessments – Results can sometimes differ between assessors, which may affect eligibility.
• Scheme limits – ECO Plus is mainly for insulation. Solar panels and heat pumps are usually supported under different schemes.

Understanding these points helps set fair expectations before applying.

A Household Story: From Draughty to Comfortable

Take the example of Mrs Davies, a pensioner living in a 1950s semi-detached house in EPC band F. Her heating bills were high, and her living room always felt cold. Through So Eco, she checked her eligibility and found she qualified for loft and cavity wall insulation under ECO Plus.

An accredited installer carried out the work. Within weeks, her home felt warmer, and her heating use dropped. Mrs Davies now expects to save several hundred pounds a year, but more importantly, she feels comfortable in her own home again.

This kind of outcome is exactly why schemes like ECO Plus exist.
