The Complete Guide to the ECO4 Scheme: How to Secure Your Free Internal Wall Insulation
Are you struggling with rising energy bills and a home that never feels truly warm? The solution could be simpler than you think. Thanks to the UK Government’s Energy Company Obligation (ECO4) scheme, you may qualify for free internal wall insulation — transforming your comfort while reducing your heating costs.
This complete guide from Creed Energy Solutions explains how the ECO4 scheme works, who qualifies, and how you can claim your free insulation with our simple, stress-free process.
Understanding the ECO4 Scheme: A Lifeline for UK Households
The ECO4 scheme is the fourth phase of the UK government’s flagship energy efficiency initiative, running from April 2022 to March 2026. Under this programme, major UK energy suppliers must fund energy-saving home improvements for eligible households.
The scheme has two key goals:
Helping low-income and vulnerable households reduce energy costs
Reducing carbon emissions to support the UK’s net-zero commitments
ECO4 focuses on improving the least energy-efficient homes — often older properties with solid walls, which lose heat far more quickly than modern buildings. That’s why internal wall insulation is one of the most valuable measures available through this scheme.
Who Qualifies for Free Internal Wall Insulation?
Eligibility for ECO4 depends on both your property and household circumstances.
Property Requirements
Your home must have solid walls (common in houses built before 1920).
The property must be privately owned or privately rented (with landlord consent).
Your home should have a low EPC rating (bands D to G).
Benefit Requirements
You or someone in your household must receive at least one of the following qualifying benefits:
Universal Credit
Pension Credit (Guarantee or Savings Credit)
Income-based Jobseeker’s Allowance (JSA)
Income-related Employment and Support Allowance (ESA)
Child Tax Credit
Working Tax Credit
Income Support
Housing Benefit
Special Note on Child Benefit Eligibility
If you receive Child Benefit, you may still qualify depending on your total household income and number of children. Creed Energy Solutions can help you assess eligibility during your free check.
Why Internal Wall Insulation Is Essential for Solid Wall Homes
If you live in a period or solid-wall property, you’ve likely noticed how hard it is to keep it warm. These walls can lose up to 45% more heat than insulated cavity walls, leading to higher bills and constant discomfort.
Internal wall insulation creates an effective thermal barrier, delivering benefits such as:
Up to 70% reduction in heat loss
Elimination of cold spots and draughts
Consistent, even room temperatures
Reduced condensation and damp issues
Lower carbon footprint and energy bills

Common Homeowner Questions
“Will insulation make my rooms smaller?”
Not significantly — modern materials are slim and efficient. Most rooms lose just 100–150mm per insulated wall, a small trade-off for a warmer, more comfortable space.
“Is installation disruptive?”
Not at all. Most installations take 3–5 days per room, and our team works carefully to minimise mess. Scheduling and room access are discussed in advance.
“Will ventilation be affected?”
No — professional installation ensures your home remains well-ventilated. In fact, insulation can improve air quality by reducing condensation and mould growth.
