FREE Underfloor

Free Underfloor Insulation Grants Borders

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

Addressing this overlooked area of heat loss by investing in floor insulation proves to be a valuable endeavor. Although the initial cost can be substantial, with larger homes potentially facing expenses of up to £3,000, the long-term benefits outweigh the financial investment.

Underfloor insulation presents a non-invasive solution that effectively retains heat within the home, resulting in reduced heating bills and overall improved energy efficiency. Recognizing the importance of this measure, the Scottish government is actively supporting homeowners through grants available via the government’s Energy Company Obligation (ECO) scheme. This initiative aims to make underfloor insulation more accessible, ensuring that more households can benefit from enhanced energy efficiency and reduced heating costs.

The primary objective of the ECO initiative is to assist Scotland in fulfilling its international commitment to diminish the nation’s carbon emissions. To accomplish this goal, major energy corporations are mandated to allocate funds towards enhancing the energy efficiency of residential properties. Eligible individuals can benefit from this scheme by having energy-saving upgrades funded through these designated funds.

Under the ECO4 program, which succeeded the ECO3 initiative in 2022 and operates until 2026, and the Affordable Warmth Obligation, which is a component of the ECO directive, qualifying individuals may receive free installation of underfloor insulation, subject to specific eligibility criteria.

Installation of underfloor insulation beneath wooden or suspended timber floors can potentially reduce home heat loss by as much as 15%.

The underfloor insulation grant, covering the cost of installation, is accessible to homeowners, owner-occupiers, or tenants, provided they have obtained consent from the property owner.

Why apply for the underfloor insulation grant?

In Borders, homeowners with wooden or suspended floors may qualify for complimentary underfloor insulation, provided they meet eligibility requirements. Upon approval, certified installers will visit your residence to install the insulation. This upgrade aids in heat retention, reducing energy expenses and enhancing overall home comfort.

While self-financing underfloor insulation can incur substantial costs, this scheme eliminates the need for any repayment. Beneficiaries reap the advantages of underfloor insulation, including improved warmth and reduced utility bills.

The ECO4 initiative remains accessible until March 31, 2026, after which grant criteria or availability may change. Seizing the opportunity to benefit from these grants while they’re currently available is advisable.

Do You Qualify
For Free Underfloor Insulation?

Qualifying for free floor insulation is subject to specific criteria, ensuring fair distribution of resources.

Homes built post-1980 typically lack eligibility due to their construction featuring solid concrete floors, unlike older residences with wooden flooring. Exceptions exist for houses with basements or built on slopes, provided there’s sufficient clearance beneath the ground floor, usually a minimum of one meter, accessible through a hatch.

Another condition entails dedicating at least two-thirds of the dwelling’s footprint for underfloor insulation. Even if insulation was previously installed, updating with contemporary materials might be an option. These measures ensure equitable access to energy-efficient upgrades, aligning with sustainability goals and promoting comfortable living environments.

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 property is a perfect fit for every type of insulation solution. While wall or loft insulation might be suitable for some homes, underfloor insulation presents its own unique considerations.

Properties equipped with cellars, basements, or underfloor crawlspaces often provide an ideal setting for underfloor insulation, provided there’s approximately one meter of clearance beneath the floor.

A prevalent feature in older properties, suspended timber floors offer a prime opportunity for insulation. These floors not only tend to lose significant amounts of heat but also offer ample space for insulation installation. Essentially, suspended timber ground floors consist of floorboards resting on joists above an open area.

Homes featuring air bricks or ventilation bricks in the exterior walls, positioned below the damp-proof membrane on the ground floor level, are also prone to heat loss. Such residences may even qualify for complimentary underfloor insulation services.

To effectively insulate the floor beneath a suspended structure, one common method involves laying insulating mineral fibers beneath the exposed floorboards. These fibers are then secured in position using netting, which is fastened to the joists for stability.

Alternatively, a contemporary approach to floor insulation involves the application of spray foam. This foam expands upon application, adhering to the underside of wooden floors and effectively trapping heat within the room above.

It’s important to note that installing floor insulation beneath concrete floors is impractical due to the absence of space beneath the concrete. In such cases, insulation is applied by layering it on top of the concrete floors to ensure effective thermal retention.

The Advantages
Of Underfloor Heating

Ensuring your home remains cozy and energy-efficient extends beyond typical insulation methods like wall insulation and double-glazed windows. Underfloor insulation stands as a pivotal component in regulating indoor temperatures and offers a range of additional advantages, such as:

Improved thermal efficiency

Underfloor insulation is a key factor in enhancing the thermal efficiency of any home. By preventing heat loss through the suspended timber floor, it contributes significantly to energy conservation. When combined with wall and loft insulation, it ensures homes remain warm even during the coldest months. Moreover, it also keeps homes cooler on hot days by blocking heat from entering through flooring gaps.

Mess-free installation

Installing floor insulation is remarkably simple and mess-free. Since the installation takes place beneath the floorboards, between the joists, it doesn’t disrupt activities on the ground floor. There’s no mess involved, making it a hassle-free process for homeowners.

Reduced heating bills

Improved thermal efficiency directly translates to reduced energy consumption and, consequently, lower heating bills. Homes equipped with underfloor insulation can maintain a consistent and comfortable temperature with minimal effort from heating systems. This not only saves money but also contributes to environmental sustainability by reducing energy usage.

No need to redesign your floors

Unlike redesigning timber flooring to enhance thermal efficiency, underfloor insulation eliminates the need for extensive renovations. The insulation materials can be seamlessly installed beneath the floor without major construction work. Additionally, existing underfloor insulation can be upgraded with modern, more effective materials, often covered by insulation grants.

Enhanced comfort

Underfloor insulation ensures that homes remain comfortable throughout the year. Cold and draughty floors, especially during winter, can be uncomfortable. Insulation prevents cold air from seeping through old floorboards, maintaining a cozy indoor environment.

Increased house value

Energy-efficient homes are highly sought after in the real estate market. Properly insulating the home, including floors, walls, and lofts, enhances its value and attractiveness to potential buyers.

Reduced condensation

In colder climates like Borders, uninsulated floors can lead to condensation and mold growth due to temperature differentials. Underfloor insulation helps maintain warmer floor surfaces, reducing the risk of condensation-related issues.

Noise reduction

Insulation also contributes to noise reduction, particularly in basements or multi-storey homes. It effectively minimizes the transmission of noise between floors, enhancing overall comfort.

Cost savings

Underfloor insulation not only saves on upfront installation costs, especially if eligible for grants, but also yields long-term financial benefits through reduced heating expenses. Despite initial investment, it eventually pays for itself by lowering utility bills.

Health and well-being

Living in a comfortable home with stable temperatures positively impacts occupants’ health and well-being. Cold, draughty, or damp environments can lead to health issues, particularly in vulnerable populations. The availability of free underfloor insulation grants, such as ECO4, is crucial for ensuring the well-being of such individuals.

Underfloor Insulation
Building Regulations

In Borders, adherence to specific building regulations concerning underfloor insulation and flooring upgrades is imperative. Governed by the Building Standards 2017, these regulations outline essential criteria for insulation and flooring enhancements in the UK.

Scotland’s Building Standards are particularly focused on enhancing energy efficiency and minimizing heat loss across all structures. These standards align closely with broader UK guidelines, ensuring consistency in regulatory approaches.

One pivotal criterion under Scotland’s regulations is the U-value, which measures thermal performance. For upgraded floors, the U-value must not exceed 0.18 W/m2K in Scotland, reflecting a rigorous commitment to energy efficiency. In contrast, in England, Wales, and Northern Ireland, the minimum allowable U-value stands at 0.25 W/m2K. This discrepancy underscores Scotland’s more stringent stance on energy efficiency standards within the UK framework.

How Much Could You Save A Year?

In Borders, underfloor insulation can range from £300 to £3,000 for larger properties. However, under the ECO4 scheme, you can get it for free, focusing on ground floors. This leads to significant annual savings on energy bills, according to the Energy Saving Trust.

By installing this insulation, you will experience significant cost savings on your annual energy bill. According to the Energy Saving Trust, you can expect to annually save, on average:

• Detached house: £65

• Bungalow: £60

• Semi-detached house: £40

• Mid-terraced house: £25

The ECO scheme also offers other grants including room in roof (loft) insulation grants, cavity wall insulation, solid wall insulation, and inefficient gas boiler replacement.


Certainly! You have the flexibility to select the installer for your insulation needs. However, it’s important to note that the chosen installer must be officially registered, approved, and authorized to carry out the work under the ECO scheme. While you have the freedom to make a selection, your options might be limited to those who meet these criteria.

Underfloor insulation installation is a swift and tidy process. Once you’ve been confirmed as eligible, you’ll be provided with a scheduled installation date. The duration of installation typically varies depending on the property’s size and the accessibility to the underfloor area. In urgent situations, there are emergency services available that can complete the installation within a single day.
