FREE Underfloor

Free Underfloor Insulation Grants Glasgow

Many homeowners prioritize insulating walls and roofs to improve energy efficiency, often overlooking the significant heat loss that occurs through the floor. Even with cavity or solid wall insulation, as much as 20% of a home’s heating can escape through uninsulated floors.

Investing in floor insulation proves to be a valuable consideration, despite the potential cost of up to £3,000 for larger homes. Underfloor insulation presents a non-intrusive solution that not only warms up living spaces but also reduces heating expenses and enhances overall energy efficiency.

Recognizing the importance of such initiatives, the Scottish government offers grants for underfloor insulation as part of the Energy Company Obligation (ECO) scheme. These grants aim to assist homeowners in Glasgow and beyond, making energy-efficient upgrades more accessible and affordable.

The primary objective of the ECO initiative in Glasgow is to align with Scotland’s commitment to reducing its carbon footprint on a global scale. Under this scheme, prominent energy corporations are mandated to allocate resources towards enhancing the energy efficiency of residential properties. Qualifying individuals stand to benefit from energy-saving enhancements funded through this program.

Under the ECO4 program, which succeeded ECO3 in 2022 and is slated to continue until 2026, alongside the Affordable Warmth Obligation component, residents may qualify for complimentary installation of underfloor insulation, subject to specific eligibility criteria.

By installing underfloor insulation beneath wooden or suspended timber floors, homeowners can potentially curtail heat loss by as much as 15%, contributing to overall energy conservation efforts.

This grant for free underfloor insulation is open to homeowners, occupants who own their residence, or tenants with consent from their landlords, ensuring broader accessibility to energy-saving measures across diverse housing arrangements.

Why apply for the underfloor insulation grant?

Having wooden or suspended floors could entitle you to a fantastic opportunity: completely free underfloor insulation. However, meeting specific criteria is essential to qualify for this benefit.

Upon approval, skilled installers will visit your residence to fit the underfloor insulation. This installation plays a crucial role in retaining heat within your home, consequently reducing energy expenses and enhancing overall comfort.

While you could opt to pay for underfloor insulation independently, the costs could amount to thousands of pounds. Fortunately, through this initiative, you won’t incur any expenses yet still enjoy the advantages of warmer floors and improved insulation.

It’s important to note that the ECO4 scheme, facilitating these grants, is only valid until March 31, 2026. Beyond this date, alterations to the grant criteria or the grants themselves might occur. Thus, seizing this opportunity while it’s available is highly advisable.

Do You Qualify
For Free Underfloor Insulation?

Not everyone in Glasgow will meet the requirements for free floor insulation. Here’s what you need to know:

Houses built during or after the 1980s are unlikely to qualify. Older homes typically have wooden floors, while newer ones have solid concrete ground floors.

If your house has a basement or is built on a slope with a crawlspace beneath the ground floor, you might be eligible. However, there must be at least one meter of headroom underneath the floor and access through a hatch.

At least two-thirds of your home’s footprint must be available for underfloor insulation installation.

If you’ve previously had underfloor insulation installed, you might still qualify for an upgrade using modern materials.

There are also criteria that must be met by the homeowner occupying the house where the underfloor insulation is required. The homeowner must be a receiver of any of the following:

  • Pension Credit (Savings Credit or Guarantee Credit)
  • Employment and Support Allowance
  • Jobseeker’s Allowance
  • Working Tax Credit
  • Income Support
  • Child Tax Credit
  • Universal Credit
  • Housing Benefit

If your household’s annual income is £31,000 or less, you will also qualify under the ECO4 scheme.

In addition to all this, the house must be situated in Scotland, Wales or England and must be heated by gas.

Is Your Property Suitable
For Underfloor Insulation?

Not every dwelling is compatible with all forms of insulation. Even if your residence is conducive to wall or loft insulation, underfloor insulation presents its own prerequisites and considerations.

Residences equipped with cellars, basements, or underfloor crawlspaces generally accommodate underfloor insulation, provided there’s approximately one meter of clearance beneath the flooring.

Older properties often feature suspended timber floors, which are amenable to insulation. These floors not only experience significant heat loss but also offer sufficient space for insulation installation. Characterized by floorboards resting on joists above an aperture, these suspended timber ground floors offer an ideal opportunity for insulation enhancement.

Furthermore, homes fitted with air bricks or ventilation bricks in the exterior walls below the damp-proof membrane on the ground floor level also suffer considerable heat loss. Such residences might qualify for complimentary underfloor insulation upgrades, addressing both energy efficiency and comfort concerns.


Installing floor insulation beneath a suspended floor in Glasgow involves laying insulating mineral fibre below the visible floorboards and securing it with netting fastened to the joists. Alternatively, a contemporary method is to employ spray foam, which adheres to the underside of wooden floors, effectively retaining warmth within the room above.

However, it’s essential to note that for properties with concrete floors, traditional floor insulation methods are impractical due to the absence of space beneath the concrete. Instead, insulating concrete floors entails layering insulation material directly on top of the existing floor surface.

The Advantages
Of Underfloor Heating

Ensuring your home in Glasgow stays cozy and energy-efficient entails more than just upgrading wall insulation and installing double-glazed windows. Delving into underfloor insulation can significantly impact your comfort levels while offering a range of additional advantages, such as:

Improved thermal efficiency

Enhancing the thermal efficiency of homes in Glasgow is paramount for ensuring comfort and energy savings, particularly in the face of fluctuating weather conditions. Underfloor insulation plays a pivotal role in achieving this goal by significantly reducing heat loss through suspended timber floors. When combined with wall and loft insulation, it creates a cohesive barrier that prevents heat from escaping during winter and keeps interiors cooler in the summer months.

Mess-free installation

One of the key advantages of underfloor insulation is its hassle-free installation process. Since the insulation is fitted beneath the floorboards, between the joists, there’s minimal disruption to daily activities, and no mess is left on the ground floor. This seamless installation ensures that homeowners can enjoy the benefits of improved thermal efficiency without the inconvenience of extensive construction work.

Reduced heating bills

mproved thermal efficiency translates to reduced energy consumption and lower heating bills for Glasgow residents. With underfloor insulation in place, homes can maintain a consistent temperature more efficiently, reducing the strain on heating systems.

No need to redesign your floors

Unlike major renovations that may require a complete overhaul of timber flooring, underfloor insulation offers a cost-effective solution that preserves the architectural integrity of older homes in Glasgow. By installing insulation materials beneath the existing floors, homeowners can enhance thermal efficiency without the need for extensive redesign or construction.

Enhanced comfort

Underfloor insulation not only improves energy efficiency but also enhances the overall comfort of living spaces. By eliminating draughts and maintaining stable temperatures, it ensures a cozy environment year-round, especially during the chilly Glasgow winters. Additionally, it mitigates noise transmission between floors, fostering a quieter and more tranquil home environment.

Increased house value

Investing in underfloor insulation yields long-term financial benefits for homeowners in Glasgow. Eligible residents may qualify for insulation grants, reducing upfront installation costs. Furthermore, the enhanced energy efficiency and comfort provided by underfloor insulation can increase the overall value of properties, making them more appealing to potential buyers in the competitive real estate market.

Reduced condensation

In Glasgow’s damp climate, uninsulated floors are susceptible to condensation and mold growth, posing health risks to inhabitants. Underfloor insulation helps maintain warmer floor surfaces, minimizing the risk of moisture-related issues and creating a healthier indoor environment for residents.

Noise reduction

If you have a basement that is often used, insulation can help reduce the noise that travels up between the floors. This also applies to multi-storey homes where insulation can be installed between levels.

Cost savings

Not only will you save on the costs of upfront installation if you are eligible for an insulation grant, but in the long term, you also stand to save a lot of money. Even if you have to pay out of pocket for your home’s insulation, over time it will pay for itself thanks to the reduction in heating bills.

Health and well-being

By creating comfortable living spaces with stable temperatures, underfloor insulation positively impacts the health and well-being of Glasgow residents. Particularly for vulnerable populations, such as those on income-related benefits, living in a warm, draught-free environment is crucial for preventing illnesses and promoting overall wellness.

Underfloor Insulation
Building Regulations

In Glasgow, adhering to specific building regulations is essential when considering the installation of underfloor insulation and upgrading flooring.

Guidance provided by the Building Standards 2017 outlines the necessary standards for insulation and flooring upgrades in the UK. These standards are primarily geared towards enhancing energy efficiency and bolstering the building’s insulation envelope.

Scotland’s Building Standards are designed to minimize heat loss and enhance the overall energy efficiency of buildings across the country. These standards are aligned with guidelines established throughout the UK.

When upgrading flooring in Scotland, it’s crucial to ensure that the U-value (thermal performance standard) does not exceed 0.18 W/m2K. In contrast, in England, Wales, and Northern Ireland, the minimum U-value requirement is 0.25 W/m2K. This distinction underscores Scotland’s commitment to prioritizing stringent energy efficiency measures.

How Much Could You Save A Year?

Investing in professional underfloor insulation may seem daunting due to the potential cost ranging from £300 to £3,000, especially for larger properties. However, an alternative avenue exists through ECO4, which offers free underfloor insulation. Moreover, you only need to insulate your ground floor, easing the financial burden.

Opting for this insulation solution promises substantial savings on your yearly energy expenses. As per the Energy Saving Trust’s findings, the average annual savings you can anticipate include:

• Detached house: £65

• Bungalow: £60

• Semi-detached house: £40
