Energy efficiency has become a top priority for UK homeowners who are looking forward to reducing their energy bills, minimising heat loss, and creating a more comfortable environment in your home. One of the most effective ways to achieve this is through proper home insulation. Selecting the right insulation can make a significant difference to your comfort and monthly expenses, whether you live in a detached house, a semi-detached property, or a flat.
It can be challenging to know which one suits best for your property, when so many options are available out there. Each option offers you unique benefits depending on factors such as budget, property age, and energy-saving goals. In this comprehensive guide, we will explore the most popular insulation options in the UK to help you make an informed decision that improves your home’s efficiency and reduces your carbon footprint.
Understanding the Importance of Home Insulation
Before looking at the different types of home insulation, it is important to understand why insulation matters. Insulation helps keep your home comfortable by reducing heat loss in winter and heat gain in summer. Without proper insulation, up to 33% of heat can escape through walls, 25% through the roof, and around 10% through the floors.
You can significantly lower your energy consumption by investing in the right insulation to keep your home warmer in winter and cooler in summer, and ultimately reduce greenhouse gas emissions. Insulation also contributes to a more sustainable lifestyle and a healthier planet, apart from just saving money on energy bills.

Solid Wall Insulation
You can choose between internal and external solid wall insulation for older properties. Internal insulation involves fixing insulated boards to inside walls, while external insulation adds a protective insulating layer to the outside of the building.
Solid wall insulation tends to be more expensive but offers you excellent results, compared to other types of home insulation that are available particularly for period properties. It not only improves energy efficiency but also enhances soundproofing and reduces condensation inside your home.
External & Internal Wall Insulation
- External Wall Insulation (EWI): This involves applying an insulating material, such as rigid boards or mineral wool, to the outside of your home before covering it with a protective render or cladding. EWI improves thermal performance, shields the property from weathering, and can refresh the overall appearance of the building. It is especially effective for homes exposed to wind and rain. However, planning permission may be required in some areas, particularly for listed buildings or properties in conservation zones.
- Internal Wall Insulation (IWI): This method uses insulated boards or stud walls fixed to the inside of external walls. It is generally more affordable than EWI and does not change the outside appearance of the property, making it ideal for homes where external alterations are not possible. The main drawback is a slight reduction in internal room space, but it still provides excellent thermal improvement and can be installed room by room for flexibility.
Loft Insulation
Loft insulation is a widely used, affordable, and efficient way to insulate homes in the UK. Since a large amount of heat escapes through the roof, insulating your loft can make an immediate difference to your home’s energy efficiency.
There are two main methods of doing it. Laying rolls of mineral wool or using rigid boards for tighter spaces. Mineral wool insulation is also cost-effective and easy to install, while rigid boards provide better thermal performance in compact areas. On average, loft insulation can save homeowners hundreds of pounds annually on energy bills which makes it a smart and long-term investment.

Cavity Wall Insulation
Many homes in the UK have cavity walls, particularly older buildings. The process of cavity wall insulation uses materials such as mineral wool, foam, or polystyrene beads to fill the gap between two external brick walls. This is one of the most popular choices among all types of home insulation because it reduces heat loss through walls, which are a common source of wasted energy.
It’s a quick and minimally disruptive process carried out by professionals, and it is highly cost-effective in the long run. However, it’s important to ensure your property is suitable as homes with damp issues or poor ventilation may require additional preparation before installation.
Floor Insulation
Heat can also be lost through floors, especially in older homes that come with suspended timber flooring. Floor insulation helps create a thermal barrier beneath your home to reduce drafts and improve overall comfort. Rigid foam boards are commonly used under solid floors, while mineral wool can be fitted between joists for timber floors.
While this is one of the less common types of home insulation, it can make a noticeable difference when it is combined with loft and wall insulation. Properly insulated floors also prevent cold spots and your home feels consistently warm during the winter months.
