To really enjoy the benefits of a warm and efficient home, the right use of insulation is absolutely essential. Internal wall and loft insulation is enhancing the comfort and affordability of living spaces all across the UK, providing major energy savings over time. However, prioritising these types of improvements is how you can achieve the most beneficial outcomes for your investment.
Let’s take a closer look at how internal wall insulation works, and see if it’s right for you.
What is Internal Wall Insulation and How Does it Work?
Internal wall insulation involves fitting insulation material directly to the inside of your outside facing walls. This creates a bit of a thermal barrier that retains warmth during the colder months and reduces heat from entering during warmer months, keeping indoor temperatures under control.
For you, this means the rooms you spend the most amount of time in will heat up faster and stay warm, ensuring comfort without having to continuously adjust your thermostat.
Signs Your Home Might Need Internal Wall Insulation
If certain rooms in your home feel particularly cold in winter or overly warm in summer, or if heating bills are uncomfortably high, these are clear indicators that your insulation may be in need of improvement. Internal wall insulation might be the solution for you.
Older homes, especially Victorian period, with solid or stone walls, often lack insulation, which can lead to high energy consumption, as your heating system works overtime to make up for the heat loss that’s happening through those solid walls. A lot of picturesque properties suffer because of this, where we have to sacrifice comfort to retain the character of the building.

Types of Properties Suitable for Internal Wall Insulation
Homes built with solid walls
Listed buildings
Properties within conservation areas
Properties experiencing internal moisture issues
Properties with a lot of outdoor noise
All of the above will see real improvements in comfort and energy saving, with the installation of internal wall insulation.
Think internal wall insulation might be the solution for you? Fortunately, there’s more that can be done to improve its effectiveness, and there’s support out there to help you achieve it!
Enhancing the Effects with Loft Insulation
Combining loft insulation with internal wall insulation essentially forms a protective shield around your home, trapping heat in winter and repelling heat in summer more than before.
This additional step means that heat produced within your home doesn’t escape upwards and out, ensuring every penny spent on energy is used to its fullest potential. This combination also regulates indoor temperatures, removing uncomfortably hot or cold spots and creating a more stable environment at home.
Why Top Up Your Loft Insulation?
For loft insulation to work, it must be installed properly. Loft insulation requirements are now set at a minimum of 270 millimetres thickness. Topping up existing insulation can be essential, to achieve the energy efficiency you need. A well-insulated loft can prevent up to a quarter of your home’s heat from escaping through the roof!
For you, this means less need for heating, cost savings on energy bills, and a decrease in carbon emissions.
Finding Financial Support for Home Insulation
Government schemes like ECO4 provide partial or full funding options which can make these essential upgrades more accessible. These financial schemes aim to encourage energy saving efforts and make sustainable living achievable and affordable for more households.
The best way to investigate getting funding towards home improvements like these is checking your eligibility with RES. From there, we can determine which government schemes are worth applying for, which home improvements you should be looking at prioritising and look into getting a home energy assessment arranged for you.
