About Cavity Wall Insulation?

Essentially, a cavity wall is a wall that has a space, a.k.a, a cavity, in between another wall. This spacing between the two walls can be filled with insulation to provide various benefits for the homeowner.

Cavity walls are considered to be a more modern form of construction, with most properties built post-1940s having this cavity. 

Therefore, if your home has a cavity wall, you are presented with a great opportunity to insulate it and reap the benefits of saving money, reducing heat loss, soundproofing and much more.

Why do you need to insulate your cavity walls?

Benefits of Insulating your Cavity Walls

Did you know that up to 33% of energy is lost through your walls? This makes wall insulation the most sought-after area for any residential property. Save money, reduce your bills and minimise your carbon footprint by insulating your cavity walls.

Save Money

Because you lose up to 33% of energy through your walls, by insulating these areas, you can start to save money on your energy bills every month.

Efficient cavity wall insulation can drastically help with energy-saving, which means money-saving too.

Your walls are perhaps most notorious for heat loss, so we 100% recommend this form of insulation.

Environmentally Friendly

As you start to reduce your energy consumption, you will simultaneously begin to reduce your carbon footprint because your energy output is lower. 

Cavity wall insulation is a big step towards becoming carbon neutral and having that eco-friendly property that homeowners sought after.

Therefore, your investment into cavity wall insulation is one not only for yourself but one that benefits the environment too.


An added benefit of having insulation installed into your cavity walls is that it can provide a great soundproofing solution.

If your home is situated in a noisy area, on the main road or surrounded by noisy neighbours, then cavity wall insulation can help.

Give your home the ultimate peace of comfort and sound with insulation to help reduce noise pollution.

Ease of Installation

You may think insulation jobs require a lot of time, effort and disruption to your daily lives. Well, with cavity wall insulation, it is minimally invasive and offers little-to-no disruption.

Our professionals drill small holes in strategic positions across your wall. Then, they begin to inject the insulation materials via the holes drilled in, filling up the wall with sufficient insulation before covering over the small holes previously made.

Good work all round, all questions answered promptly and thoroughly, folks knew their stuff and were careful to check the best possible result given existing bits of broken polystyrene in the back wall. Larger than average 3 bed semi done in about 3.5 hours once they were set up. More aesthetic than practical, but I was particularly pleased with how well they matched the morter to the existing one for filling the holes at the end of the job. 25 year warantee was a particularly nice touch. Came sooner than booked due to a cancellation which was a bonus. Really noticing the difference already.

The 2 engineers did an excellent job of keeping the drilling holes to a minimum and cleaned up very well afterwards. In addition to the cavity wall insulation, they also had to fit a new vent due to our wood burner in the living room. They checked with us throughout the project that we were happy with what they were doing and asked for feedback at the end. Very professional and polite guys. We will hopefully learn over the hot summer and cold winter how effective the work has been. Well done team!

Terry Dunford did the surveying for our property he was very knowledgeable and gave very good advice which we check and was correct in everything he said. The men who came do the cavity wall insulation were also very good, they respected us and our home,they explained what they were going to do and warned us about the noise. They cleared up after they had completed the work and asked us to check that we were happy with the way they had left our property which we were. We would highly recommend this company to anyone thinking of having any cavity wall insulation done .

Frequently Asked Questions

A cavity wall consists of two layers of masonry (brick or block) with a gap, or cavity, in between. This design helps with insulation and moisture control, making buildings more energy-efficient and less prone to dampness.

If your property was built or renovated after the mid-1920s, it is likely to have a cavity wall. However, to determine if you have cavity wall insulation, you can schedule a call with our professionals who will assess the presence and condition of existing insulation.

The installation process usually takes a few hours to complete, depending on the size of the property. Our experienced technicians work efficiently to minimise disruption, and you can typically expect the installation to be completed in a single day.

A cavity wall has an empty space (cavity) between its outer and inner layers of masonry, which provides an opportunity to install insulation. A solid wall, on the other hand, lacks this gap, making insulation installation more complex and costly. Cavity wall insulation is a relatively straightforward way to improve energy efficiency.

Yes, cavity wall insulation significantly improves the thermal efficiency of your property by saving up to 33% of lost heat. It helps to prevent heat loss through the walls, keeping your home warmer in winter and cooler in summer. This insulation can lead to reduced energy consumption and lower heating bills.

Prior to the installation, we recommend clearing any furniture, belongings, or obstacles away from the walls being insulated. This will allow our technicians easy access to the walls. Additionally, we advise discussing any specific requirements or concerns with our team during the initial consultation.
