What is the Great British Insulation Scheme (GBIS)?
The Great British Insulation Scheme (formerly ECO+) is a government-backed initiative designed to help eligible UK households improve their home’s energy efficiency with free or subsidised insulation upgrades. Launched in summer 2023 and running until March 2026, the scheme focuses on making homes warmer, more comfortable, and more affordable to run.
By reducing heat loss, insulation helps maintain a steady indoor temperature, cutting down on energy bills and carbon emissions.
At Eco Energy Source, we offer a range of energy-efficient solutions through GBIS, including:
Cavity Wall Insulation
Loft Insulation
Room-in-Roof Insulation
We’ll assess your home and recommend the most effective upgrade tailored to your property.

How Does Cavity Wall Insulation Work, and What Are the Cost Savings with GBIS?
If your home has cavity walls, there’s a gap between the inner and outer walls where heat can easily escape. Insulating this space prevents heat loss, helping to keep your home warmer in winter and cooler in summer.
By filling your cavity with high-quality insulation, we help reduce your energy bills and improve comfort in your home.
Plus, if you’re eligible for the Great British Insulation Scheme (GBIS), installation is completely free.
Your insulation also comes with a 25-year insurance-backed guarantee (IBG), giving you peace of mind that it will continue saving you money for years to come.

Lowering Your Carbon Footprint

Does Loft Insulation Work, and Will GBIS Help Make Energy Savings?
Yes, loft insulation works, and it plays a vital role in keeping your home energy-efficient. Over time, even if your loft has insulation, it can lose its effectiveness, especially if it’s below the recommended 270mm thickness. This results in heat escaping from your home, leading to higher energy bills.
If you’re eligible, GBIS can help by installing new insulation to bring your loft up to the recommended standard, ensuring your home stays warm and cosy in winter while helping you save on energy costs.
If your home doesn’t have loft insulation, we can install it with a £500 contribution. If there’s existing insulation but it’s below the recommended 270mm, a higher contribution may be required to reach the ideal level.
How Does Room-in-Roof Insulation Work?
Room-in-roof insulation involves installing insulation boards between the rafters in attic conversions or loft rooms, creating a thermal barrier that helps prevent heat loss and reduces energy bills. This type of insulation is perfect for lofts converted into living spaces, making them warmer and more energy-efficient.
You may qualify for grants or funding that covers most of the installation cost. Check your eligibility to find out more about room-in-roof insulation grants.
Reduce Your Energy Costs with an Air Source Heat Pump
An air source heat pump extracts heat from the air to warm your home. Not only will it lower your energy bills, but it will also reduce the carbon dioxide emissions, contributing to a greener future. Through the Boiler Upgrade Scheme, the government will provide £7,500 towards the cost of installation.
To ensure your heat pump operates efficiently, it’s crucial that your home is well-insulated. If your loft and walls lack sufficient insulation, heat will escape, causing the heat pump to work harder and potentially undoing any savings on energy.
Whether you’re investing in a heat pump or simply improving your home’s energy efficiency, proper insulation will help you save on energy costs.

This FAQ section answers common questions about the scheme, including eligibility, benefits, available insulation types, and the application process. Learn more about how GBIS can help you save on your energy costs and contribute to a greener future.
The GBIS is a government-backed initiative aimed at improving the energy efficiency of homes across Great Britain. It provides free or subsidised insulation to eligible households, helping to reduce energy bills and carbon emissions. The scheme is set to run until March 2026.
Eligibility is primarily based on your home's Energy Performance Certificate (EPC) rating and your Council Tax band. Generally, you may qualify if:
Homeowners have an EPC rating of D or lower.
Private renters have an EPC rating of D or E.
Your property falls within specific Council Tax bands (A to D in England; A to E in Wales and Scotland).
Savings vary based on your home's size and current insulation status. For example, installing cavity wall insulation can save up to £240 annually in heating costs for a typical semi-detached home. Loft insulation can save up to £230 per year.
You can apply through approved installers like Eco Energy Source. They will assess your eligibility based on your EPC rating, Council Tax band, and receipt of qualifying benefits. It's recommended to have your landlord's permission if you're renting.
For eligible households, insulation may be provided free of charge. However, if your property doesn't meet certain criteria, you might need to contribute towards the installation cost. For instance, first-time loft insulation installation requires a £500 contribution if your home lacks existing insulation.
