Free External Wall Insulation

If your home has solid external walls and struggles to retain heat, you could be eligible for a free External Wall Insulation grant under the UK Government’s ECO4 or GBIS schemes. This funding helps homeowners upgrade their insulation, cut energy bills, and enjoy a warmer, more efficient home — all at little to no cost.

What is External Wall Insulation?

External Wall Insulation (EWI) is a method of adding an insulating layer to the outside walls of your home, finished with a protective render or cladding. It helps prevent heat from escaping, keeping your home warmer for longer and reducing energy waste.

By insulating from the outside, EWI avoids disrupting the interior and eliminates cold bridging, reducing condensation and damp issues. Homeowners benefiting from government-backed ECO4 or GBIS insulation grants can often get EWI installed free of charge or at a heavily subsidised rate, helping to lower energy bills while improving comfort and sustainability.

How External Insulation Keeps Your Home Warm

External Wall Insulation (EWI) adds a layer of insulation to the outside of your walls, helping stop heat from escaping through the brickwork. This creates a strong thermal barrier that keeps your home warm in winter and cool in summer. You’ll notice fewer cold spots and less condensation all year round.

At EcoGrants Scotland, we install durable EWI systems that improve your home’s energy efficiency and protect it from damp and weather damage. By reducing heat loss and cold bridging, EWI helps lower your heating bills, boosts your EPC rating, and makes your property warmer and more sustainable.

Will External Wall insulation Save Me Money on Energy Bills?

Absolutely — External Wall Insulation (EWI) is one of the most effective ways to lower your energy bills and make your home more comfortable. Around 35% of heat escapes through uninsulated walls, meaning a large portion of your heating is wasted. By adding an insulating layer to your external walls, EWI locks in warmth, reduces heat loss, and helps maintain a steady indoor temperature throughout the year. This means your heating system won’t need to work as hard, cutting both energy use and carbon emissions.

At EcoGrants Scotland, we work with homeowners across the UK to make homes more energy-efficient through the ECO4 and GBIS government grant schemes. These grants can often cover the full or partial cost of installing EWI, depending on eligibility. Once fitted, you can enjoy lower heating bills, a more sustainable home, and greater comfort — all while improving your property’s external appearance and value.

Frequently Asked Questions

Does external wall insulation affect my property’s value or mortgage?

Yes — external wall insulation can increase property value by improving your EPC rating and energy efficiency. Most mortgage lenders view EWI as a positive home improvement, especially when it’s installed under certified ECO4 or GBIS standards.

Can external wall insulation be installed on semi-detached or terraced houses?

Absolutely. EWI works on semi-detached, detached, and end-terrace homes, and even some mid-terrace properties where access allows. We carefully match render finishes to neighbouring homes to maintain the overall look and compliance with local planning rules.

Will I need planning permission for external wall insulation?

In most cases, EWI falls under permitted development and doesn’t require planning permission. However, if your property is listed, in a conservation area, or has a unique façade, we’ll guide you through the local planning process to ensure full compliance.

Can external wall insulation be combined with other energy-saving measures?

Yes, and it’s often recommended. Pairing EWI with loft insulation, solar panels, or a new heating system can maximise your home’s energy savings. Under the ECO4 scheme, combining measures can increase your funding value and overall efficiency.

Will external wall insulation make my home quieter?

Definitely. One of the hidden benefits of EWI is soundproofing. The insulation and render layers help absorb external noise, making your home noticeably quieter — ideal for properties near busy roads or urban areas.

What materials are used in external wall insulation systems?

At EcoGrants Scotland, we use premium insulation boards such as EPS, mineral wool, or phenolic foam, combined with breathable render finishes. This ensures long-lasting performance, weather resistance, and full compliance with PAS 2030 standards.

How do I know if my existing render needs to be removed before installation?

During your free home survey, our team assesses your existing walls for cracks, paint coatings, or loose render. If necessary, we’ll remove or repair these areas before applying EWI to guarantee the best adhesion and finish.

How is external wall insulation maintained after installation?

EWI requires very little upkeep. A gentle wash every few years keeps it looking new. We recommend occasional inspections after extreme weather to check for cracks or impact marks — simple steps that ensure long-term performance and appearance.

Can I get a government grant for external wall insulation?

Yes! Through the ECO4 and GBIS government schemes, many households across the UK can receive external wall insulation free of charge or heavily subsidised. EcoGrants Scotland can check your eligibility and manage the full application for you.
