Free flat roof insulation could save you £355 on your energy bills

Around a quarter of heat losses in a home is via a poorly insulated roof. With an ECO4 loft insulation grant you could save £355 per year on your energy bills.

Why do I need flat roof insulation?

As heat rises, around a quarter of the heat lost in your home escapes through the roof. Many flat roofs have been constructed with either no or very little insulation. If your home has either a full flat roof or an extension with a flat roof we can upgrade your flat roof with insulation. As well as helping reduce your energy bills, you will also benefit from a new roof covering.

According to the Energy Saving Trust, a gas heated semi-detached house with no roof insulation could save £355 on their heating bills per year.

As well as making your home warmer in the winter, flat roof insulation will also help keep your home cooler in the summer.

What is flat roof insulation?

Flat roof insulation involves installing a layer of insulation on top of your existing roof to provide you with a Warm Roof.

We will lay insulation of around 120-150mm over the existing roof felt before installing a a plywood deck and new weatherproof membrane above this.

Not only could you save hundreds of pounds per year, but you will also reduce your carbon emissions. A typical semi-detached house with a flat roof would reduce carbon emissions by around 610kg per year.


When you install insulation you are reducing the amount of air that can circulate. Poor ventilation in a loft can lead to condensation forming which can cause mould and damp patches to appear on ceilings.

To ensure that this doesn’t happen we will bring your homes ventilation up to the latest standards and install additional ventilation where required as part of the ECO4 grant.

Do I qualify for a free insulation grant?

To qualify for a free insulation grant, you (or your tenant if you are a landlord), must be in receipt of one of the benefits listed below:

Child Benefit (conditions apply)
Child Tax Credit
Employment & Support Allowance
Housing Benefit
Income support
Job Seekers Allowance
Pension Credit Guarantee Credit
Pension Credit Savings Credit
Universal Credit
Working Tax Credit
Warm Homes Discount

I’m not receiving one of these benefits, can I be helped?

Up to 50% of energy efficiency measures installed in England, Wales and Scotland can be completed through the ECO4 Flex scheme and is for households whose combined gross income is below £31,000 per year or if you have certain health conditions which would make you vulnerable to the cold.

The ECO4 Flex scheme is administered by Local Authorities who are responsible for rolling it out in your area and they will verify your income or health eligibility. It is rolling out slowly and is expected to be fully live by April 2023.

We will check as part of your application if your area is now open for applications.

I’m a Landlord, can I get any help?

The Minimum Energy Efficiency Standards (MEES) came in to effect in April 2018 and means that all rented properties must now have a minimum energy efficiency rating of band ‘E’ unless exempted.

However, from 2025, all properties rented on new tenancies must meet a minimum energy efficiency rating of Band ‘C’ and properties with existing tenants must be brought up to this standard by 2028. Failure to do so could result in a fine of up to £30,000.

These changes are in line with the Government’s net zero emissions by 2050 targets and will also apply to properties which are being sold from 2035.

How can we help?

If your tenant is receiving one of the benefits listed above your property will be eligible for a grant to improve your property, including installing flat roof insulation.

In fact, the ECO4 scheme says that all Band ‘E’ rated properties must reach a minimum Band ‘C’ after installation of energy efficiency measures.
