ECO4 Scheme

Serving the entirety of Airdrie, we specialize in providing fully funded ECO 4 grants tailored for lower-income households and individuals receiving benefits. Our commitment lies in reducing the carbon footprint of Airdrie households, thereby lowering energy bills and contributing to Scotland’s Net Zero goal.


The Energy Company Obligation 4 (ECO4) scheme presents an excellent opportunity for eligible homeowners seeking complimentary cavity wall insulation. Jointly funded by the Scottish and UK governments, this initiative aims to empower homeowners to adopt energy-saving measures within their properties.

By assessing a home’s insulation, heating systems, and electricity usage, the ECO4 scheme seeks to enhance power efficiency, thereby reducing energy expenditure and addressing fuel poverty concerns. This is particularly crucial amid the prevailing cost-of-living crisis.

Moreover, individuals from vulnerable demographics, including the disabled, pensioners, and children, stand to benefit from the ECO4 scheme. This inclusive approach underscores the government’s commitment to ensuring equitable access to a sustainable future for all.

The installation of free insulation serves as the cornerstone of the ECO4 scheme. Without adequate insulation, any heating system improvement may fail to deliver the desired heating effect. Northern Energy estimates that approximately 35% of a home’s heat is lost through uninsulated walls.

Under the ECO4 scheme, eligible participants may avail themselves of various energy-efficient measures, including insulation upgrades, air source heat pumps, first-time central heating installations, solar PV systems, electric storage heaters, and non-condensing gas boiler upgrades.

What Is Cavity Wall Insulation?

Cavity wall insulation involves enhancing a home’s energy efficiency by filling the gap (cavity) between inner and outer walls with an eco-friendly insulating material. This process prevents heat from escaping through the walls, maintaining warmer interiors in winter and cooler environments in summer.

What Are The Advantages Of Cavity Wall Insulation?

Cavity wall insulation offers a plethora of benefits, making it an excellent choice for enhancing your home. Here are the key advantages of this type of insulation:

  1. Energy Saving: Cavity wall insulation plays a crucial role in reducing heat loss from your home, particularly through the walls. This translates to decreased energy consumption for heating and cooling, leading to lower energy bills over time.

  2. Comfort: Insulating cavity walls ensures a more consistent indoor temperature throughout the year. You’ll notice fewer cold spots and draughts during winter while enjoying cooler interiors in summer, resulting in enhanced comfort regardless of the season.

  3. Reduced Carbon Emissions: By minimizing energy usage for heating, cavity wall insulation contributes to lower carbon emissions. This eco-friendly choice aids in shrinking your carbon footprint and actively combating climate change.

  4. Less Condensation: Cavity wall insulation establishes a thermal barrier, reducing the likelihood of condensation formation on interior walls. This not only helps prevent dampness but also mitigates the risk of mould growth, thereby improving indoor air quality.

  5. Quick Installation: Compared to solid wall insulation, cavity wall insulation boasts quicker and simpler installation procedures. Typically completed within a few hours, the installation process causes minimal disruption to your daily routine.

  6. Enhanced Property Value: A well-insulated home is inherently more appealing to potential buyers. By investing in proper insulation, you can boost your property’s resale value, making it a more attractive proposition in the real estate market.

  7. Longevity: Cavity wall insulation is renowned for its durability and longevity. Once installed, it can last for many years without requiring maintenance or replacement, providing long-term benefits and peace of mind.

How Much
Can Cavity Wall Insulation Save You?

The savings from cavity wall insulation can vary depending on factors such as home size, property type, and average energy consumption. Here’s an overview of the potential annual energy bill savings for a typical gas-heated home in Scotland:

You’ll also be saving on cavity wall insulation installation costs if you are eligible for the ECO4 insulation grant. Installation costs for this type of insulation can reach a maximum of:


To ascertain if your home already has cavity wall insulation, start by checking your EPC for a rating between A and C, suggesting insulation presence. Alternatively, inspect your outer walls for old or sealed drill marks, indicative of insulation installation. Experience of draughts near walls or absence of loft insulation may suggest insufficient or absent cavity wall insulation. Consulting a professional insulation company for assessment is another option.

The first thing to do if you want to check if you already have cavity wall insulation is to check your EPC. You’ll want to look for a rating between A and C, which means it’s likely your home has insulation.

If you’re still unsure, you can also check in one of the following ways:

  • Since cavity wall insulation installation involves drilling into your external walls, you can examine your outer walls for old or sealed drill marks. If there is a drilling pattern, your home is likely insulated.
  • If you experience draughts in your home (particularly near the walls), your home may not be insulated or your walls only have very thin insulation.
  • If you have access to your loft, check for loft insulation. If there is no insulation, it’s likely that your walls won’t have any either.
  • Consult a professional insulation company to help you assess your home’s insulation.

Other than cavity wall insulation, the ECO4 scheme also offers the following types of insulation grants, should you be eligible to receive them:

  • External wall insulation
  • Room-in-roof insulation
  • Flat roof insulation
  • Loft insulation
  • Internal wall insulation
  • Solid wall insulation
  • Underfloor insulation
