Homes which usually have uninsulated walls are typically those built with walls of solid brick or stone construction, or those known as non-traditional/system-built properties which are typically built with prefabricated concrete panels or timber/steel framed. These properties tend to have an increased heat loss compared to modern housing and means you spend a lot of money to warm up your property for it to escape through the walls relatively quickly.
The best solution to prevent this is to insulate the walls of your home by adding insulation to the outside or the inside walls of these property types. This is like putting an overcoat on your property that is durable, energy efficient and in the case of external wall insulation can improve the visual appearance of your home.
As a homeowner, this means you can reduce your energy usage through by slowing the rate of heat escaping from your home. This will help even out the temperature inside your home and it will significantly reduce draughts, which will make it a much more comfortable, warmer and healthier space to live in.
What will solid wall insulation make my property look like?
A property that has had the benefit of external wall insulation looks refreshed.
Typically, local authorities will allow works to proceed if the resulting look is of similar appearance to its existing condition, or is in keeping with the properties in the local area. This is known as permitted development.
The exact appearance and finish will be discussed and confirmed with you prior to any works proceeding – we offer various render finishes and those proposed will be clearly outlined to you and agreed.
How do we find the right energy efficiency solution for you?
We’ll organise a time and date to suit you to conduct an onsite assessment of your home. This means we can recommend the solution that works best for your home. It includes:
Energy Assessment
The aim of an energy assessment is for qualified energy surveyor to undertake a detailed review of your home to identify the most suitable energy efficiency measure(s) improvements to your property.
An Energy Performance Certificate (EPC) will be produced, and recommendations outlined to you.
Depending on the size and complexity of your home, the assessment will likely take 1–2 hours, and includes a few key steps:
Insulation Survey
Conducted at the same time as the energy assessment, this is a technical review to note all the details we would need to fit internal/external wall and/or loft insulation to your property. Checks would include condition of walls, windows, doors, roof and where any services such as telephone cables, electrical cables or meter boxes connect with the inside of your home.
Rest assured we have processes to ensure minimal disruption but also to safeguard any finer details when working on your home. We will take note and detail any items that may be included/excluded in this home improvement and detail that to you in your personalised quote.

External Wall Insulation/Guarantees
Sustainable Building Services (UK) Ltd (TrustMark Licence Number: 1743630) is approved for installation of internal/external wall insulation.
We are certified by the British Board of Agrément (BBA) to install to the latest Government Quality Standards, known as PAS 2030:2019 standard. We’re also members of the National Insulation Association and the Solid Wall Insulation Guarantee Agency (SWIGA).
We use the highest-quality products and have partnered with PermaRock Products Ltd, one of the UK’s longest established insultation suppliers. They audit our installations to ensure the highest quality standards are always maintained. To provide further peace of mind, we provide you with both an independent 25 year guarantee and product guarantee. The independent guarantee covers all workmanship materials and is fully transferable should your property be sold.
Benefits of external wall insulation
-
Your home will be more energy efficient – lowering your energy usage and bills
-
Future impact of energy price increases / fluctuations will be limited giving you peace of mind
-
Your property will be a healthy and more comfortable space to live
-
You’ll experience minimal disruption during installation – you remain in your home with safe and easy access to your property
-
The appearance of your outer walls will be improved (external wall insulation)
-
Your walls will have improved weatherproofing and sound resistance
-
Draughts will be reduced, making your home more cosy
-
Condensation on internal walls can be reduced and help prevent damp (but will not solve rising or penetration damp).
-
The lifespan of your walls will increase because its existing substrate will be protected
-
Ventilation improvements will be made during the installation which will improve the living conditions in your home (see below)
-
Can be installed without planning permission in most instances (‘Permitted’ Development)
Moisture & Ventilation
In a solid wall property moisture usually moves quite freely throughout the building. We now know that moving air in and out of a property in a controlled manner is great for our health but most importantly it doesn’t have to be to the detriment of how warm or comfortable our home is.
When we breathe, cook, clean, dry clothes or have showers/baths in our homes we generate water vapour. Therefore, the more people that live in a property the more water vapour is created.
Whilst insulation closes the gaps around the edges of the walls and windows to reduce draughts the balance is to ensure the stale air and water vapour generated by living is moved to the outside of the property, leaving you feeling comfortable and healthy in your home and preventing condensation, damp or mould.
We will give you advice on this in our design brief to ensure there is controlled ventilation in your property. This could include but is not limited to:
- Electrical Extractors* in kitchens and bathrooms
- Trickle vents in windows
- Core vents for Open Fires
Energy Savings
Energy Bill Savings (£/year)
Here’s how much you could save on your energy bill (£/year) as well as how many kilograms of CO₂ emissions you could save each year with solid wall insulation.
Estimates based on insulating a gas-heated home. Costs may vary significantly depending on level of work required. Above estimates are based on a typical install, ranging from a small flat to a large detached home. Prices are based on fuel prices as of July 2024.
This means if you live in a semi-detached house you can typically save £290/year on your energy bills by having external wall insulation done. The EST have used fuel prices at July 2024.
CO₂ Savings (kgCO₂/year)
Here’s how much a typical installation could you, how much you could save on your energy bill (£/year) as well as how many kilograms of CO₂ emissions you could save each year by insulating an uninstalled loft with 270mm of loft insulation.
Estimates based on insulating a gas heated home. Costs may vary significantly depending on level of work required. Above estimates are based on a typical install, ranging from a small flat to a large detached home. Prices are based on fuel prices as of Jul 2024. Find out more about how we made these calculations.
For those of you who are carbon conscious we can see that a typical semi-detached property can save 900 kg/CO₂ per year by having external wall insulation done.
As a home hero you are lowering your carbon footprint by using less energy and you will be protected from the changes in energy prices much more than before.
