FREE Underfloor

Free Underfloor Insulation Grants Aberdeen

Many homeowners prioritize insulating walls and roofs for energy efficiency, often overlooking the significant heat loss potential through their property’s floors. Even with cavity or solid wall insulation, as much as 20% of a home’s heating can still escape through the floor.

Considering floor insulation is a wise investment, albeit it can be pricey, especially for larger homes, costing up to £3,000. However, opting for underfloor insulation can prove highly beneficial. This non-invasive process not only helps to heat up your home effectively but also reduces heating bills and enhances overall energy efficiency. Recognizing its importance, the Scottish government is providing grants for underfloor insulation through the Energy Company Obligation (ECO) scheme.

The ECO scheme aims to align with Scotland’s international commitments to reduce carbon emissions. Major energy companies are mandated to allocate funds toward improving home energy efficiency. Eligible individuals can have energy-saving measures, such as underfloor insulation, covered by this fund.

Under the ECO4 scheme, which succeeded ECO3 in 2022 and continues until 2026, and the Affordable Warmth Obligation within the ECO directive, you may qualify for free underfloor insulation installation if you meet specific eligibility criteria, discussed below.

By installing underfloor insulation beneath wooden or suspended timber floors, you can potentially reduce home heat loss by up to 15%. This free grant is accessible to homeowners, owner-occupiers, or tenants, provided they have landlord permission.

Why apply for the underfloor insulation grant?

If your home boasts wooden or suspended timber floors, you stand a chance to benefit from free underfloor insulation grants, provided you meet the eligibility criteria. Upon approval, qualified installers will ensure the seamless installation of underfloor insulation, leading to improved heat retention, reduced energy bills, and a more comfortable living environment.

Opting for this scheme eliminates the financial burden associated with underfloor insulation, making it an enticing proposition for homeowners looking to enhance their homes’ energy efficiency. Given that the ECO4 scheme is operational until March 2026, seizing this opportunity sooner rather than later is advisable.

Do You Qualify
For Free Underfloor Insulation?

While the allure of free underfloor insulation is undeniable, not all homeowners will meet the eligibility criteria. Homes constructed during or after the 1980s with solid concrete ground floors are unlikely to qualify. However, properties featuring basements or built on slopes with adequate headroom beneath the floor may be eligible.


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 all homes can accommodate every type of insulation. Even if your home is suitable for wall or loft insulation, underfloor insulation requires specific conditions.

Properties with cellars, basements, or underfloor crawlspaces are typically conducive to underfloor insulation, provided there is approximately one meter of headroom beneath the floor.

Suspended timber floors, common in older properties, are also suitable for insulation. These floors not only experience significant heat loss but also offer ample space for insulation installation. Such floors consist of floorboards resting on joists above an open space.

Homes featuring air bricks or ventilation bricks in the exterior walls below the damp-proof membrane at ground floor level are also prone to heat loss. These properties may qualify for free underfloor insulation.

Innovative solutions for floor insulation have emerged, catering to diverse home structures and needs. One method involves utilizing insulating mineral fiber beneath exposed floorboards, firmly secured with netting fastened to the joists. This approach not only enhances thermal efficiency but also ensures durability and stability within the flooring structure.

Alternatively, spray foam insulation presents a contemporary option, offering versatility and effectiveness. Applied beneath wooden floors, the foam expands, adhering seamlessly and creating a robust barrier that traps heat within the room above. This method not only optimizes energy conservation but also provides a seamless insulation solution for various floor types.

However, it’s essential to recognize that concrete floors pose a unique challenge for traditional floor insulation methods. Due to the absence of space beneath the concrete, conventional insulation techniques are impractical. Instead, addressing concrete floor insulation entails a different approach, typically involving the layering of insulation materials directly onto the concrete surface. By employing innovative strategies tailored to specific floor compositions, homeowners can achieve optimal energy efficiency while ensuring comfort and sustainability within their living spaces.

The Advantages
Of Underfloor Heating

Creating a cozy and sustainable living environment encompasses more than just traditional insulation methods like wall insulation and double-glazed windows. Often overlooked, underfloor insulation significantly contributes to achieving optimal thermal comfort while offering additional advantages:

Improved thermal efficiency

By reducing heat loss through the floor, underfloor insulation contributes to overall energy efficiency, ensuring homes remain warmer in winter and cooler in summer.

Mess-free installation

Underfloor Insulation
Building Regulations

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

The Building Standards 2017 offers comprehensive guidance on meeting prescribed standards concerning insulation and flooring. These standards prioritize energy efficiency and the overall insulation envelope of buildings.

Scotland’s Building Standards aim to minimize heat loss and enhance the energy efficiency of all structures, aligning with broader UK guidelines.

For upgraded floors in Scotland, the U-value, which measures thermal performance, must not exceed 0.18 W/m2K. Conversely, in England, Wales, and Northern Ireland, the minimum U-value required is 0.25 W/m2K. This contrast underscores Scotland’s more stringent stance on energy efficiency standards.

How Much Could You Save A Year?

While professional installation of underfloor insulation can range from £300 to £3,000, particularly for larger properties, you have the opportunity to obtain it for free through ECO4. Moreover, you’re only required to insulate your ground floor.
