Free Cavity Wall Insulation Scottish Borders

Free cavity wall insulation grants for properties in the Scottish Borders can be claimed through a new home energy efficiency grant scheme. The Energy Company Obligation (ECO), which is Government led, is designed to lower carbon emissions. It also helps Scottish households deemed to live in “fuel poverty” areas of the Borders lower the cost of heating their homes. Installing  cavity wall insulation and loft insulation is one of the most effective ways of reducing energy costs.

Currently cavity wall insulation is free for many people in the private sector (home owners, private tenants and landlords). If you live in a council property all regions in Scotland have their own plans to improve the energy efficiency of their housing stock.

What is cavity wall insulation?

Cavity wall insulation is a material which is used to reduce heat loss in your home. It works by filling the gap in between the bricks in your walls. This reduces the transfer of heat from within your home to the outside. Over a third of the heat from your home escapes through your outer walls. So installing wall insulation can mean substantial savings on energy costs.

Is cavity wall insulation suitable for your home?

Properties in the Scottish Borders before the 1920’s have solid brick or stone walls. If your home was built after this is a good chance it have a cavity in between the bricks of your outer walls. Scottish homes built with solid walls during this period are in a minority. Our surveyors can confirm this by drilling a small hole in your wall and looking inside with specialized equipment..

Your house will usually be suitable for cavity wall insulation if:

  • your external walls are unfilled cavity walls
  • your cavity is at least 50mm wide
  • the masonry is in good condition
  • it was built after the 1920’s

Cavity Wall Insulation – Benefits

Cavity Wall Insulation stops heat escaping out through the walls of your home. Around 35% of heat in the average home in the Scottish Borders is lost through the outer walls of the house. Under the current Government ECO scheme, hundreds of thousands of Scottish homeowners, landlords and private tenants qualify for a grant for free cavity wall insulation.

If your home was built after 1920, it probably has walls  with a gap or cavity between them. Cavity wall insulation fills that gap, keeping the warmth in to save energy. It can also help reduce condensation inside the house if this is a problem on your external walls.

The cavity wall insulation that is installed through the ECO grant scheme a man made fibre similar to loft insulation, but finely chopped so as to fit in between your walls. It is moisture proof and cannot pass dampness from your exterior wall to the interior wall via the cavity.

Installing cavity wall insulation is like putting a coat on your house. The insulation keeps the heat in, meaning that you can have your central heating on for less time, or turn in down to a lower level. This costs you less in gas / fuel bills and reduces harmful emissions which are released into the environment. Cavity wall insulation also keeps your home cooler in the summer.

Do I already have Cavity Wall Insulation?

If you think you already have Cavity Wall Insulation it is recommended that you ask an authorised Insulation Surveyor to check. It is a simple process. Fill in the Insulation Enquiry Form for more information.

How do I get Free Wall Insulation?

Getting a free insulation grant in the Scottish Borders is a straightforward process. You can arrange an appointment with an Approved Surveyor by  entering your details in the  Enquiry Form opposite.

A certified and approved insulation surveyor will then contact you to arrange a cavity wall survey. This involves drilling a small hole in your external wall and looking inside with a boroscope to see if your walls have a cavity and if they already have insulation.

The surveyor will then fill out a grant application and the cavity wall insulation company will then come and fill your walls.

Wall Insulation FAQ’s

Is my home suitable for cavity wall insulation?

If your house was built between the 1920’s and the 1990’s it is likely that your exterior walls have a double skin of bricks with have a cavity, or gap, between them. Houses built before this period were built with solid stone. Any residential properties built lkater than ths are likely to have insulation already installed.
If your home was constructed using solid walls, or has a timber frame, it is not suitable for cavity wall insulation.

What material is used to insulate walls?

There are three main types of materials used to insulate walls. Polystyrene beads, mineral wool fibre and foam insulant. Although all three are manufactured to British building standards foam is rarely used now to insulate residential properties.

How can I tell if my walls have a cavity?

You can tell the type of walls you have either by measuring the thickness of the wall near the door. If it is 260mm or more then you probably have a cavity. Another waqy is to look at the pattern of the bricks on your walls. The diagram below shows how cavity walls have a regular brick pattern so as to leave a gap in between the brick leafs. Solid walls have an alternative pattern as no space is required in between the bricks.

Finding an approved insulation installer

If you are unsure whether your home is suitable for wall insulation let us know and we can arrange a free no obligation survey with an approved energy assessor. The assessor will drill a small hole in one of your elevations. By using specialised camera equipment called a borescope the surveyor will check to see if you already have insulation in your walls and advise if you are eligible for a Government insulation grant.
