ECO4 Scheme

Should you be eligible, the Energy Company Obligation 4, or ECO4, scheme is a great option to consider when looking to get free cavity wall insulation installed. This initiative is funded by the Scottish and UK governments and is designed to assist homeowners in adopting energy-saving measures in their homes.

It does this by focusing on enhancing a home’s power efficiency by assessing its insulation, heating systems, and electricity usage. Upgrading these features can help households cut down on their energy bills and potentially aid in alleviating fuel property. This is a major concern for property owners, especially when considering the everpresent cost-of-living crisis.

Linking to this, those on lower incomes and who are considered the most vulnerable in our society – such as those who are disabled, pensioners, and children – are at the forefront of benefitting from the ECO4 scheme. This is because the government understands that the drive towards creating a greener future should be an equal one that everyone can benefit from.

Installing free insulation forms the basis of the ECO4 scheme. Without a properly insulated house, any heating system improvement may not provide the desired heating effect. To illustrate this, Northern Energy estimates that around 35% of your home’s heat is lost through uninsulated walls.

Under the ECO4 scheme, you could be eligible to receive a range of energy-efficiency measures, including:

  • Insulation (including cavity wall insulation)
  • Air source heat pump
  • First-time central heating
  • Solar PV
  • Electric storage heater
  • Non-condensing gas boiler upgrade

Who Is Eligible
For The ECO Wall Insulation Grant?

To qualify for the ECO wall insulation grant, you will need to meet a certain list of criteria. Usually, the ECO4 grant gives preference to homes facing fuel poverty, individuals who struggle to pay their energy bills, and rural homes, as these are often the most vulnerable groups.

Grant eligibility

The criteria homeowners and tenants must meet to qualify for the grant are as follows:

  • You own your own home and are currently living in it, or you’re renting from a private landlord. If you are a private tenant, you must have the landlord’s permission to apply for the grant and to complete installation. This also means that you are not living in a council-owned home. In this case, you would not be eligible for this grant.

  • There is at least one person living in the home who meets the following criteria:
    • Low-income households. These households are defined as those where the combined household income is less than £31,000 per annum.
    • A minor under the age of five years old lives in the home.
    • One of the residents of the home is over 65 years old and is either vulnerable or suffers from specific health conditions.

  • The home is located in an area that is vulnerable to colder living conditions.

  • For homeowners: Your current Energy Performance Certificate (EPC) rating is E, F or G. As part of the grant, you will be required to have loft insulation, roof insulation, and internal and cavity wall insulation.

  • For private tenants: Your EPC rating should be E, F or G to qualify.

Note: It’s important to remember that all homes are required to undergo an assessment by a qualified surveyor. The surveyor will determine whether or not the home meets the eligibility criteria.

What Is Cavity Wall Insulation?

Cavity wall insulation is a method of making a home or building more energy efficient by filling the gap (or the ‘cavity’) between the inner and outer walls. This is done using an eco-friendly insulating material, which helps to prevent heat escaping through the building’s walls. In turn, this keeps the interior of the building warmer in the winter and cooler in the summer.

What Are The Advantages Of Cavity Wall Insulation?

Cavity wall insulation comes with several benefits that make it a great choice for your home. The most common advantages of this type of wall insulation include:

  • Energy saving: Cavity wall insulation significantly reduces the amount of heat escaping from your home – particularly from your walls. This means that you will need to use less energy for your home when it comes to heating and cooling, which results in lower energy bills.

  • Comfort: By insulating a cavity wall, you’re allowing your home to maintain a more consistent indoor temperature. You’ll experience fewer cold spots and draughts in winter, and your home will be much cooler in summer. This means you’ll be more comfortable all year round.

  • Reduced carbon emission: By using less energy for heating, you’re naturally helping to reduce carbon emissions. This environmentally friendly choice helps to reduce your carbon footprint and actively helps to combat climate change.

  • Less condensation: Cavity wall insulation helps to create a thermal barrier, reducing the likelihood of condensation building up on your interior walls. Not only can this help to prevent dampness, but it can also help to avoid mould. Less mould also means better air quality in your home.

  • Quick installation: Cavity wall insulation is far easier and quicker than solid wall insulation. Usually, the installation only takes a few hours, which means there will be minimal disruption to your schedule.

  • Property value: An insulated home is much more attractive to potential buyers. By insulating your home properly, you can increase its resale value in the future.

  • Longevity: Cavity wall insulation is highly durable and can last for years without the need for maintenance or replacement.

How Much
Can Cavity Wall Insulation Save You?

The cost savings from cavity wall insulation can vary depending on the size of the home, the type of property and the average energy usage for the home. However, here’s an overview of what you can expect to save on your energy bills every year if you live in 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:

FAQs

There are a few methods you can use to tell if your home has cavity walls. One of the easiest ways to do this is by checking your EPC, if you have it. You can also access your EPC on the Energy Performance Certificate Register online.

Alternatively, you can measure the thickness of your walls. Using a tape measure, start at a door or window and measure the distance between the outside and the inside wall. Usually, if a wall is more than 260mm thick, it is likely a cavity wall. Solid walls are typically less than 260mm thick.

It is also important to note that houses built after 1920 are more likely to have cavity walls, while homes built before this typically have solid walls. Of course, if you’re still not sure, you can consult a professional.

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
