External wall insulation London: 10 reasons to insulate your house

If you live in London, you know how expensive it can be to heat your home in winter and keep it cool in summer. You may also be aware of the environmental impact of using fossil fuels to power your heating and cooling systems. That’s why external wall insulation (EWI) is a smart investment for your home. EWI is a process of applying a layer of insulation material to the outside walls of your house, covering it with a protective render or cladding. EWI can improve the thermal performance, appearance and value of your property, as well as reduce your carbon footprint. Here are 10 reasons why you should consider external wall insulation for your London home.

1. Save money on energy bills with external wall insulation

EWI can significantly reduce the amount of heat that escapes through your walls, which means you need less energy to maintain a comfortable temperature inside your home. According to TheGreenAge, EWI can save you up to £500 per year on heating bills if you have solid walls without a cavity. Even if you have cavity walls, EWI can still save you up to £250 per year by eliminating thermal bridging and improving air tightness.

2. Increase the value of your property with external wall insulation

EWI can enhance the curb appeal and attractiveness of your home by giving it a fresh and modern look. You can choose from a variety of colours and finishes for your render or cladding, depending on your personal preference and budget. EWI can also increase the energy efficiency rating of your property, which can boost its market value and appeal to potential buyers.

3. Reduce noise pollution with external wall insulation

EWI can act as a sound barrier between your home and the outside world, reducing the impact of traffic noise, neighbours’ music or other sources of disturbance. This can improve your quality of life and well-being by creating a quieter and more peaceful environment for you and your family.

4. Protect your walls from damp and mould with external wall insulation

EWI can prevent moisture from penetrating into your walls, which can cause dampness, mould growth and structural damage over time. By keeping your walls dry and warm, EWI can extend their lifespan and prevent costly repairs in the future.

5. Improve indoor air quality with external wall insulation

EWI can help you avoid condensation problems inside your home by creating a more stable temperature difference between the inside and outside surfaces of your walls. This reduces the risk of mould spores forming on your walls or ceilings, which can trigger allergies or respiratory issues for some people.

6. Reduce carbon emissions

EWI can lower your reliance on fossil fuels for heating and cooling your home, which means you emit less greenhouse gases into the atmosphere. This helps you contribute to tackling climate change and meeting national targets for reducing carbon emissions.

7. Benefit from external wall insulation grants or incentives

EWI may be eligible for grants or incentives from various schemes that aim to promote energy efficiency improvements in homes across London and England such as Green Homes Grant Scheme. These schemes may cover part or all of the cost of installing EWI depending on certain criteria such as income level or property type.

8. Enjoy hassle-free installation

EWI does not require any major structural changes to your home or disruption to its interior space during installation unlike internal wall insulation (IWI). You do not need to move furniture or redecorate after installing EWI as it is applied externally only. The installation process usually takes around two weeks depending on the size and complexity of your project.

9. Choose from reputable installers

EWI is not a DIY job as it requires specialist skills, equipment and materials to ensure a safe and effective installation. You should always hire a qualified professional installer who has experience with EWI projects in London such as PD Rendering, TJ House Rendering , Be Constructive, Checkatrade  or TrustATrader. These installers are vetted by reputable organisations such as BBA (British Board Of Agrément), SWIGA (Solid Wall Insulation Guarantee Agency) , PAS2030 (Publicly Available Specification) , TrustMark (Government Endorsed Quality Scheme) etc., so you can trust them with delivering high-quality workmanship.

10 . Make use of waste materials

Some types of EWI use recycled materials such as EPS boards (expanded polystyrene) , blown-in spray cellulose (paper-based fibres) , open-cell spray foam (polyurethane) etc., which help reduce waste generation and landfill disposal. These materials are also biode
