Is there a government grant for cavity wall insulation?

Yes!

Through the Energy Company Obligation (ECO) scheme, it is possible for individuals on certain benefits to receive energy saving heating measures such as cavity wall and loft insulation grants for free, with all initial cost being fulfilled by funding.

This includes cavity wall insulation grants, roof insulation and free loft insulation as well as energy saving electric heaters. UKES specialises in the installation of all of these options.

The ECO scheme aims to lower the amount of fuel poverty in the UK with support from the largest energy companies in the sector.

Through other installers you might also qualify for a new boiler grant to replace an inefficient boiler and other energy efficiency methods, such as solar panels, depending upon what you need.

This is because all the funding comes from the government and large energy companies as they fulfill the Energy Company Obligation (ECO). Find out more about EON cavity wall insulation and British Gas cavity wall insulation funded from the ECO grant, if they are your energy suppliers.

It was decided in 2020 that all the main energy suppliers must help to lower carbon emissions across the UK and support the most vulnerable of their customers to pay energy efficient heating bills and offer free grants for low income families.

Without ECO, the typical cost of cavity wall insulation is around £1,200-1,500, according to the Energy Saving Trust.

It is considered best to install cavity wall insulation alongside other energy efficiency measures, such as loft insulation; if only to save you extra money and time.

Absolutely, especially if you don’t already have free cavity wall insulation in your home.

As the Carbon Saving Obligation aims to cut down on energy bill costs, the entire cost of this cavity wall insulation grant will be covered by the large energy providers.

With cavity wall insulation grants, UK energy costs should be more manageable as well as more energy efficient, fulfilling the government’s aim to have the UK carbon footprint to be neutral by 2050.

What is cavity wall insulation?

Cavity wall insulation is used to fill the spaces between internal walls and external walls, preventing warm air from escaping and allowing you to keep your energy bills low.

It can help to improve your home’s energy efficiency, which can also raise your property’s value if you ever decide to sell.

For low income households, cavity wall insulation can help to keep your heating bills affordable without the cost of installation being up to you.

Solid walls with cavity insulation fitted will not need to be refilled or altered, as the majority of cavity insulation lasts for the minimum of twenty-five years.

Unfilled cavity walls, by comparison, can lead to damp, mildew and other issues caused by cold air freely circulating through the external walls of your home.

Homes that are in the direct path of wind driven rain may require more wall insulation to be fitted, as this can break down the bricks faster and allow more heat escaping to happen.

What is cavity wall insulation made of?

Cavity wall insulation is typically made up of shredded mineral wool, polystyrene beads and glass fibre, though this will depend on the kind your installer uses.

You can either install internal wall insulation or external wall insulation depending upon what your cavity walls are like and how exposed the outer wall is to weather.

UKES recommends Earthwool as our preferred form of insulation.

How is cavity wall insulation installed?

If you have inefficient insulation and qualify for its replacement we will start with cavity wall insulation removal before we install new one.

You might think that the installation of cavity wall insulation is disruptive but it isn’t! This is because it’s a simple process of drilling specific holes in your outer wall and filling the space with at least two layers of solid wall insulation.

The whole process does not take long and will prevent heat escaping from your cavity walls going forward.
