What is internal wall insulation?

Internal wall insulation refers to the application of insulation material to the interior face of external walls to improve a building’s thermal performance. This method is particularly suitable for solid-wall homes, typically built before the 20th century, which lack the cavity walls found in more modern buildings. The main goal is to reduce heat loss, thereby increasing energy efficiency and reducing heating costs.

There are several methods for installing internal wall insulation, with the most common being the construction of a new stud wall to which insulation is added. However, this process can be disruptive, requiring the temporary removal of items like switches and radiators. It’s also important to ensure that the installation is airtight to avoid issues such as damp and condensation.

The cost of internal wall insulation can vary, but it generally ranges between £40 and £50 per square meter, potentially reaching over £100 per square meter if a new stud wall is constructed.

Why should I get internal wall insulation?

Internal wall insulation offers several benefits, making it a worthwhile investment for homeowners. Some of the key advantages include:

Improved Thermal Efficiency: Internal wall insulation helps keep heat in during winter, reducing the amount required from heating systems.

Energy Bill Savings: It can lead to potential energy bill savings of up to £270 per year in a typical 3-bedroom semi-detached property.

Increased Comfort: It reduces drafts, maintains consistent indoor temperatures, and can improve acoustic performance, providing extra comfort indoors.

Reduced Noise Pollution: It acts as a soundproofing agent, blocking out unwanted noise from traffic or neighbors.

Potential Increase in Home Value: It can increase the value of your home by improving the Energy Performance Certificate (EPC) rating.

0% VAT Benefit: Homeowners can benefit from 0% VAT on internal wall insulation, resulting in further savings.

Cost-Effective Solution: It is a cost-effective solution to significantly improve the thermal efficiency of a home and reduce energy bills.

Versatility: Internal wall insulation can easily be applied to different wall types, such as timber and stone.

How much can internal wall insulation save?

The average cost of internal wall insulation is between £40 and £50 per square meter, but it can reach over £100 per square meter, depending on the size and type of the property. The cost can vary from £4,000 to £13,000 for the entire project, with up to 60% of the cost being attributed to labor. However, homeowners could be eligible for free internal wall insulation through government schemes, help cover the cost of making energy efficiency improvements in the home.

Internal wall insulation can lead to significant savings on heating bills. According to the Energy Saving Trust, insulating the walls of a detached house could save an average of £690 annually on energy costs. 

For a semi-detached house, the savings could be around £395 per year, and for a mid-terrace house, about £235 per year. These savings also contribute to reducing carbon emissions, making it a beneficial choice for both your wallet and the environment. 

The actual savings will vary based on your property and usage, but homeowners can save up to 40% on their heating bills with internal wall insulation.

Internal wall insulation not only reduces heating costs but also can improve the comfort of a home by maintaining more consistent indoor temperatures and reducing drafts.


Grants for internal wall insulation

The Energy Company Obligation (ECO) scheme, specifically ECO4, provides grants for internal wall insulation across England, Scotland, and Wales. The scheme is designed to offer free and optimized heating and insulation solutions for households on a tight budget, with a particular emphasis on properties rated in the efficiency bands E, F, and G. To qualify for the grant, the property should be privately owned or rented and have solid walls.

Additionally, if someone living in the household receives certain income-based benefits or if the household has a combined annual income below a certain limit, they could be entitled to a grant that will cover the cost of installing internal wall insulation. The installation must be carried out by an accredited and approved installer to meet the requirements of the grant scheme.

If you’re considering applying for the ECO4 funding for internal wall insulation, you should check your eligibility and fill in the below form to initiate the process. The grant covers a range of insulation and heating upgrades, including internal wall insulation, and is part of the government’s strategy to enhance energy efficiency in households that are vulnerable to fuel poverty
