Loft Insulation – Home Energy Funding Scotland

Free Loft Insulation Grants – Government Energy Saving Scheme

Save Money & Energy with a Loft Insulation Grant

Did you know up to a third of your home’s heat can escape through the roof? If you’re a homeowner in Scotland, you could qualify for a home insulation grant through official government energy saving schemes—making your home warmer, greener, and cheaper to run.

What is a Loft Insulation Grant?

A loft insulation grant is funding provided by government schemes such as ECO4 and LA Flex to help cover the cost of installing new or topping up existing loft insulation. This means you could get your home insulated for free or at a heavily reduced cost, with no hidden charges.

Who Qualifies for Loft Insulation Grants?

You may be eligible if:

You own your home or are a private tenant (with landlord permission)
You’re in council tax bands A-E, or
Your household income is below £31,000, or
You receive certain benefits (like Universal Credit, Pension Credit, or Child Tax Credit)

Once installed, Knauf loft insulation doesn’t sag or degrade quickly, so you can count on consistent performance for decades.

8. Increases Property Value
A well-insulated home is more attractive to buyers and can boost your property’s EPC (Energy Performance Certificate) rating, potentially increasing its value.

Loft insulation is located between the joists on the loft floor of your property (Roof Insulation is located between the tiles and the rafters)

The main materials used by us are Quilted Mineral Wool (Fibre Glass or Earthwool)

The recommended depth for loft insulation is 270mm-300mm for rock wool.minimum, rising to 400mm for new builds.

There are a number of grants and schemes available to home owners which can substantially reduce the cost of installing these products.

Loft Insulation can help lower your heating bills, lower wear and tear on your boiler and reduce global warming and climate change

FAQ

What is the recommended thickness for loft insulation?

The recommended thickness for loft insulation in the UK is 400mm for mineral wool insulation, as per current building regulations. This ensures optimal energy efficiency and helps reduce heat loss through the roof.

If you’re upgrading insulation, it’s worth checking the existing thickness—if it’s less than 400mm, topping it up can significantly improve your home’s energy efficiency and lower heating bills.
I use my loft for storage but need to get it insulated, can I do this?
Assess the existing insulation: Check the current insulation levels in your loft. If there is little or no insulation, you’ll need to add new insulation.

Maintain access and headroom: When adding insulation, make sure to leave enough space for access and headroom in the loft. You’ll need a minimum of 250mm (10 inches) of clear space above the insulation.

Use appropriate insulation materials: For a loft used for storage, consider using rigid foam boards or high-density insulation, as they can support the weight of stored items. Avoid loose-fill or blown-in insulation, as they may not provide adequate support.

Install a raised storage platform: If you need to store items in the loft, consider building a raised storage platform above the insulation. This will allow you to use the loft space for storage while maintaining the insulation beneath.

Ensure proper ventilation: Make sure there is adequate ventilation in the loft to prevent moisture buildup and potential issues with the insulation. This may involve installing ridge vents, eave vents, or other ventilation systems.

Consider insulating the walls and hatches: In addition to the loft floor, you may also want to insulate the loft walls and the access hatch to improve the overall thermal efficiency of the space.

By following these tips, you can effectively insulate your loft while still being able to use it for storage. It’s always a good idea to consult with a professional insulation installer to ensure the installation is done correctly and meets any relevant building regulation
I have electrical cables in loft. Will these be a hazard in anyway?
Yes, electrical cables in the loft can potentially be a hazard when installing insulation, and you’ll need to take some precautions. Here are some key considerations:

Identify the cables: Carefully inspect the loft and identify the location of all electrical cables, including lighting, power, and any other wiring. Make sure you know where they are running.

Maintain clearance: When installing insulation, ensure there is adequate clearance around the cables. Most building regulations require a minimum of 50mm (2 inches) of space around cables to allow for airflow and prevent overheating.

Protect the cables: If the cables are not already enclosed in a conduit or trunking, consider adding protective covers or sleeves to prevent the insulation from coming into direct contact with the cables. This helps prevent damage to the cable insulation.

Avoid compressing the cables: Be careful not to compress the cables when installing the insulation, as this can damage the cables and potentially create a fire hazard.

Consider upgrading or relocating cables: If the cables are old, damaged, or not properly secured, it may be a good idea to have an electrician upgrade or relocate them before installing the insulation.

Maintain access: Ensure that you maintain easy access to the electrical cables for future inspection and maintenance purposes.

Follow building regulations: Consult with a qualified electrician or building inspector to ensure your loft insulation installation meets all relevant electrical and building safety regulations.

By taking these precautions, you can safely insulate your loft even with the presence of electrical cables. It’s always better to err on the side of caution when dealing with electrical installations.
I have sloping areas and flat roof areas within my property. Can these be insulated?

It is not always possible to do these areas. The reason being is that the timbers within these areas need to breathe and if loft insulation is fitted in these areas it can block the airflow off altogether. Access to these areas is usually minimal if at all existent. However every property has to be treated on an individual basis and the surveyor will make an assessment when visiting the property and advise accordingly.
My roof space is not big enough for an installer to stand up in. Will this be a problem?

It is very common that roof spaces are not big enough for anyone to stand up in. This is not usually a problem as the installers are usually working in a kneeling position on walkboards. Many companies within the industry work to a 1.4m height minimum for installers to gain access. It is very rare that a roof space is less than this.
I already have some insulation in the loft but it is not very thick, will this have to be removed or can it be topped up?

As much as a third of the heat you pay for could be escaping through your roof!
