External Wall Insulation
Render old and cracked? Fed up with the look of your house? Is your house cold and damp?
External Wall Insulation can cut heating costs by up to 40%.
Prices from £45 per square metre (all materials, scaffold & labour included)
Our external wall insulation service involves completely enveloping your home with high density insulation and then applying a new outer surface of your choice.
External insulation involves fixing an insulating material to external walls with a protective render or decorative cladding over the top.
The thickness of the insulation needs to be between 30mm and 100mm. It's usually installed when a building has severe heating problems or already requires some form of repair work that provides the opportunity to add insulation.
External insulation is generally more expensive than the internal type. However, it's usually the most suitable option as the installation process does not disrupt the internal design and decoration of a home.
Decorative coatings can be used to improve the appearance of the outside of your home. External insulation can also match a wide variety of home designs, such as Georgian, Victorian and Edwardian-style properties.
Grants or interest-free loans is available from the Government, Local Authorities for installing EWI.

Frequently Asked Questions
Check out the most asked questions about EWI below:
What is External Wall Insulation (EWI)?
External wall insulation (EWI) is the application of an insulation layer to the outside wall of a building in order to improve the building’s energy efficiency. By minimising heat loss in cold weather and heat gain in warm weather, EWI creates a much more comfortable living environment and reduces heating costs.
EWI is a composite system made up of three basic components: an insulant, a fixing, and a render or cladding. The insulant is secured to the wall using either special adhesives or purpose-made fixing screws/dowels. The final surface, which provides both the aesthetic and weatherproofing functions of the wall, is usually a coloured render or other specialist finish. A range of EWI systems are available allowing the building owner to prioritise between cost and technical performance.
Why should I choose EWI?
EWI has a number of benefits over other more traditional means of insulating buildings such as cavity fill or insulated dry lining. As EWI is applied to the outside of the wall, there is minimal disruption to the occupants of the building and virtually no limit to the thickness of insulation that can be applied. The combination of insulant and protective finish ensures that the entire thickness of the supporting wall remains dry and warm, avoiding structural damage and minimising the risks of condensation or mould on the walls.
The result is a very warm environment for the winter months whilst the building is kept cool in the summer. There may also be in an increase in the value of the property.
Is EWI suitable for all properties?
EWI is normally used to insulate solid wall properties, both brick and concrete, but it can also be used to further improve the performance of cavity walls. Solid walls are found in most houses built before the 1920s so, if your property dates back to Edwardian, Victorian or Georgian times, its walls are likely to be solid.
If you live in a mid-terraced property, it is possible to install EWI even if your neighbours on either side choose not to by providing a ‘stop end’ at the edge of your boundary.
If there isn’t enough room under the sills and roof overhang on your property, overcills and roof profiles can be used or it may be possible to extend the roof.
If your property is listed or in a conservation area, you may require planning permission to install EWI.
I have a non-traditional house construction; is it suitable for EWI?
If your house is of a non-traditional construction, it is highly likely to be suitable for EWI. There are many different types of non-traditional houses and it will be a case of selecting the most appropriate fixing solution for attaching the EWI system. The house wall construction must be able to support the weight of the EWI system and transfer the weight back to structurally supporting parts of the construction. It is advisable to consult someone experienced in this type of construction and, if in doubt, seek professional advice from an experienced Structural Engineer or Building Surveyor.
Do I need planning permission for EWI?
As EWI covers the whole of the outside of your property, it is likely to change its appearance and you should ask your local authority planning department whether planning permission is required to install EWI. In general though, you will not need planning permission unless the property is listed or in a local conservation area.
In a local conservation area, the decision will depend upon the planning constraints of the particular conservation area. Your local authority planning department will be able to advise on any special requirements, particularly relating to the necessary appearance of the finished works. There are a range of finishes which can be used to emulate the surrounding properties and samples can be provided to satisfy local authorities.
Further information on planning permission can be found on the Planning Portal website at www.planningportal.gov.uk.
Is there a minimum thickness of insulation that should be used?
The thickness of insulation may be dictated by the Building Regulations, which require a particular thermal performance through the wall. Green Deal Solutions will be able to calculate in conjunction with the system designer a thickness based on the wall construction and the required U-value. In the absence of Building Regulation requirements, any minimum thickness will be dictated by practical considerations. Very thin boards will be difficult to handle, particularly when a large format board, and boards will rarely be used at less than 20mm thickness.
How much does EWI cost?
Variations in both building and insulation type make it difficult to provide an estimated cost for professionally installed EWI. As a guide, it will be in the region of £45 – £70 per square metre for detached and semi-detached housing, giving a total cost of £3,600 – £5,600 for an average semi-detached house of 80 square metres. For larger properties where economies of scale are possible, the cost per square metre is likely to be less.
The final cost will be influenced by a number of factors including:
- Insulation thickness and type
- Size of the wall area
- Number of windows and doors
- Condition of the exterior surface
- Ease of installation access and any scaffolding requirements.
Payment terms should be agreed before a contract is signed with me which may include a deposit for a substantial part of the works.
What does the price incude?
The price include all materials and labour.
The depth of insulation added will depend on the construction of the existing walls and the type of material used. The price agreed will include some or all (depends on conditions) of the following:
- Provision of scaffolding
- Extension to window cills
- Extension of gas flues
- Extension to eaves and verges
- Work around soil and waste pipes
- Removal and replacement of gutters and downpipes
- Removal and replacement of satellite dishes, TV aerials, outside lights etc.
Can I get a grant or a loan for installing EWI?
Financial assistance in the form of grants or interest-free loans is available from the Government, Local Authorities and energy companies for installing EWI. Individual schemes and eligibility vary according to regional area and specific details can be obtained by visiting the Energy Saving Trust.
How much will I save on my heating bills by installing EWI?
In a poorly insulated property, it is estimated that up to one-third of the heat produced by a central heating system is lost through the walls and the roof. The Energy Saving Trust estimates that heating costs can be reduced by up to 40% by installing EWI to solid walls.
What is a U-value?
The U-value is a measure of heat loss through the walls, floor or roof of a building. The lower the U-value, the greater the resistance to heat loss and the less it will cost to heat the building. A solid brick wall will typically have a U-value of 2.0W/m²K and installing EWI can reduce this to 0.35W/m²K or better which could cut heating costs by up to 40%.
How long does EWI work take?
The length of time taken to install EWI will depend on the size of the property but, as a guide, a typical 3-bedroom semi-detached house will take approximately 3 to 4 weeks. This will include preparatory works such as extending flues and overflow pipes etc. and reinstatement of the rain water pipes.
Will I have to leave my home whilst the EWI work is carried out?
As EWI is applied to the outside walls, there is minimal disruption and it should not be necessary to vacate the property whilst EWI is installed. Although it can be a little noisy due, for example, to drilling of the walls, there should be little or no disturbance to the inside of the house and no need for redecoration. I will require good access to the walls from the outside in order to carry out the work.
What is the best way of securing the EWI system to the wall?
EWI systems can be bonded or mechanically fixed to the walls using either special adhesives or purpose-made fixing screws/dowels. Generally, if the existing wall is painted or the surface is in a poor condition, the system will be mechanically fixed. It is possible to insulate over existing render with a new system depending on the condition of the existing render and whether it is sound and well adhered to the wall.
