The Great British Insulation Scheme (GBIS) is a government-backed energy efficiency initiative launched in 2023 to help households across England, Scotland, and Wales reduce energy waste and lower their heating bills. Operated in partnership with major energy suppliers like E.ON, the scheme targets homes with poor insulation by funding a range of cost-effective insulation upgrades.
Unlike its predecessor, the ECO scheme, GBIS is designed to reach a wider range of households—including those not necessarily on low incomes. It supports both general eligibility groups (based on Council Tax bands and EPC ratings) and low-income households (those receiving qualifying benefits).
GBIS can fund measures such as:

Take The First Step
Use our form to see if you qualify for GBIS by our experienced team.
The GBIS is a government-backed scheme that helps households across the UK get free or heavily discounted insulation. It’s designed to make homes more energy-efficient and reduce heating bills — especially for properties with lower EPC ratings.
No — you may qualify even if you're not on any benefits. Many households are eligible based on their Council Tax band and EPC rating alone. We’ll check your eligibility as part of your application.
Depending on your home, you could receive loft insulation, cavity wall insulation, underfloor insulation, and more. The right type will be recommended after a free property survey.
There’s no catch. For qualifying households, insulation is fully funded or significantly subsidised. We work with accredited installers under the GBIS framework to ensure everything is compliant and cost-free where eligible.
No need — we handle the entire process on your behalf, including coordinating with E.ON. Just fill in our application form and we’ll take care of the rest.
Once you apply, you’ll typically hear from us within a few days. From survey to installation, the whole process can often be completed in just a few weeks.
We aim to minimise disruption as much as possible. Our team will provide a detailed plan and timeline before starting any work, so you’ll know what to expect.
Most insulation work is completed in a day, with minimal disruption to your home. Our registered installers are trained to work cleanly and efficiently.
Yes, absolutely. We encourage landlords to apply — especially with upcoming legal changes requiring rental homes to meet a minimum EPC rating. We can liaise with both parties to make the process smooth.
Just fill in our quick application form right here on the site. We’ll check your eligibility, arrange a free survey, and guide you through every step. No phone queues, no paperwork headaches.
Mark H
Landlord, Manchester
"As a landlord, I always strive to keep my properties competitive. When I heard about the ECO4 scheme, I decided to give it a try. The team upgraded the insulation and heating system in one of my older properties, taking the EPC rating from E to C. It’s now much more appealing to tenants, and I’ve had great feedback. The best part? It was all fully funded!"
Emma L
Landlord, Birmingham
"I had a rental property with a low EPC rating that I struggled to improve without breaking the bank. This service was a game-changer! The process was seamless, and the upgrades included cavity wall insulation and a new boiler. My property is now a C rating, and I didn’t have to spend a penny. Highly recommend it!"
Client reviews
James R
Landlord, Leeds
"One of my properties had an EPC rating of F, which was a real headache with new regulations coming into force. Thanks to the ECO4 grant, the team installed double glazing and upgraded the heating system. The property is now much more energy-efficient, and I’ve been able to justify a slight rent increase. It’s a win-win!"
Sarah T.
Landlord, Bristol
"With the new rules requiring rental properties to have an EPC rating of C or higher, I was worried about how I’d afford the necessary upgrades. This service was exactly what I needed. They handled everything, from assessment to installation, and now my property is fully compliant. It saved me a fortune!"
