FREE Underfloor

Free Underfloor Insulation Grants Edinburgh

Many homeowners in Edinburgh are diligent about insulating their walls and roofs to improve energy efficiency, yet often overlook the significance of insulating their floors. Even with cavity or solid wall insulation in place, a considerable amount of heat can escape through uninsulated floors, accounting for potential heat loss of up to 20% within a home.

Investing in floor insulation proves to be a prudent decision, given its potential to significantly enhance energy efficiency. While the cost for larger homes can reach up to £3,000, the benefits outweigh the initial expense. Underfloor insulation presents a non-intrusive solution that not only helps to retain heat within your home but also leads to reduced heating bills over time.

Recognizing the importance of energy conservation, the Scottish government offers grants for underfloor insulation through the Energy Company Obligation (ECO) scheme. These grants aim to incentivize homeowners in Edinburgh and across Scotland to adopt measures that contribute to a more sustainable and energy-efficient future. By taking advantage of these opportunities, homeowners can not only improve their living conditions but also contribute to broader environmental goals.

The primary objective of the ECO initiative in Edinburgh is to assist Scotland in meeting its international commitments to reducing carbon emissions. This program mandates major energy corporations to allocate resources toward enhancing the energy efficiency of residential properties. Eligible participants can benefit from energy-saving enhancements funded through this initiative.

Under the ECO4 scheme, operational from 2022 until 2026, along with the Affordable Warmth Obligation component, qualifying individuals may receive complimentary underfloor insulation installations. To qualify, specific criteria must be met, which will be outlined below.

Installing underfloor insulation beneath wooden or suspended timber floors can potentially decrease heat loss by up to 15%, contributing significantly to energy conservation efforts.

This grant for free underfloor insulation is accessible to homeowners, owner-occupiers, and tenants, provided they have obtained permission from the landlord as necessary.

Why apply for the underfloor insulation grant?

Homeowners with wooden floors or suspended floors have an opportunity to receive complimentary underfloor insulation, provided they meet the eligibility criteria. Once approved, certified installers will visit your residence to fit the insulation, enhancing heat retention and reducing energy expenses for a cozier living space.

While investing in underfloor insulation independently could incur substantial costs, this scheme offers a cost-free solution, allowing beneficiaries to enjoy the advantages of warmer floors without any financial burden.

The ECO4 initiative remains accessible until March 31, 2026, after which either the eligibility requirements or the grants themselves may undergo alterations. Seizing the opportunity to benefit from these grants while they are still available is advisable for Edinburgh residents keen on optimizing energy efficiency in their homes.

Do You Qualify
For Free Underfloor Insulation?

Not everyone qualifies for free floor insulation.

Homes built during or after the 1980s usually don’t qualify because they have solid concrete ground floors.

Exceptions include homes with basements or built on slopes with crawlspaces below the ground floor.

These spaces must have at least one meter of headroom and be accessible via a hatch. Also, at least two-thirds of the home’s footprint must be suitable for underfloor insulation.

If you’ve had underfloor insulation installed before, you might still qualify for an update 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?

Edinburgh, where homes vary in structure and age, it’s crucial to consider the suitability of insulation for different areas of your house. While wall and loft insulation are common choices, underfloor insulation presents its own unique considerations.

Properties equipped with cellars, basements, or underfloor crawlspaces often lend themselves well to underfloor insulation, provided there’s sufficient headroom, typically around one meter beneath the floor.

Older properties, often characterized by suspended timber floors, are prime candidates for insulation. These floors not only tend to lose a significant amount of heat but also offer ample space for insulation installation. Suspended timber ground floors typically feature floorboards resting on joists above an open space.

Additionally, homes with air bricks or ventilation bricks in the exterior walls below the damp-proof membrane at ground floor level can experience considerable heat loss. Such properties may qualify for complimentary underfloor insulation to enhance energy efficiency and comfort.

Installing floor insulation beneath a suspended floor in Edinburgh involves laying insulating mineral fiber beneath the floorboards and securing it with netting fastened to the joists. Alternatively, spray foam offers a contemporary solution, adhering to the underside of wooden floors and effectively trapping heat within the room above.

However, it’s important to note that concrete floors present a different challenge, as there’s no space beneath them for traditional insulation. In such cases, insulation is applied on top of the concrete floors to provide the necessary thermal protection.

The Advantages
Of Underfloor Heating

Ensuring your residence in Edinburgh remains snug and eco-friendly encompasses more than mere wall insulation and double-glazed windows. The inclusion of underfloor insulation significantly contributes to sustaining a cozy indoor climate while offering various additional advantages, such as:

Improved thermal efficiency

Enhanced thermal efficiency is pivotal for homes in Edinburgh, ensuring warmth during the colder months and coolness amid warmer days. Underfloor insulation serves as a cornerstone in achieving this goal by minimizing heat loss through suspended timber floors. When integrated with wall and loft insulation, it bolsters energy efficiency, effectively retaining heat and curbing energy consumption.

Mess-free installation

Underfloor insulation not only preserves heat but also prevents excessive heat from infiltrating homes on sunny days, maintaining a comfortable indoor temperature throughout the year. The installation process is seamless and mess-free, conducted beneath floorboards and between joists, enabling households to continue their daily routines without any disruption.

Reduced heating bills

One of the direct outcomes of enhanced thermal efficiency is lower heating bills, as homes require less energy to uphold a comfortable temperature. Even in Edinburgh’s cooler climate, the usage of air conditioning is diminished, as underfloor insulation acts as a barrier against outside heat penetrating the floor.

No need to redesign your floors

Unlike extensive renovations that may necessitate a complete overhaul of timber flooring, underfloor insulation offers a cost-effective solution without the need for major construction work. This allows homeowners to improve thermal efficiency without significant disruption. Furthermore, existing underfloor insulation can be upgraded with modern, more effective materials, often covered by insulation grants.

Enhanced comfort

Another advantage of underfloor insulation is enhanced comfort, ensuring a consistent and pleasant indoor temperature. This eliminates cold and draughty floors, especially discomforting during winter, thereby creating a cosier living environment.

Increased house value

Moreover, enhanced thermal efficiency increases property value, as energy-efficient homes are highly sought after in the real estate market. By investing in underfloor insulation, homeowners not only enhance comfort but also elevate the desirability and value of their property.

Reduced condensation

In addition to thermal benefits, underfloor insulation mitigates condensation-related issues, particularly prevalent in Edinburgh’s climate. By maintaining warmer floor surfaces, the risk of condensation and potential mould growth is significantly reduced.

Noise reduction

Underfloor insulation also contributes to noise reduction, particularly beneficial in multi-storey homes or basements frequently used for various activities. By installing insulation between floors, noise transmission is minimized, fostering a quieter living environment.

Cost savings

Besides upfront savings through insulation grants, the long-term cost savings of underfloor insulation are substantial. Despite initial investment costs, homeowners stand to save significantly on heating bills over time, making it a financially prudent decision in the long run.

Health and well-being

Finally, the benefits of underfloor insulation extend to health and well-being, as it creates a comfortable living environment conducive to overall health. By eliminating cold, draughty, or damp conditions, underfloor insulation helps prevent diseases, particularly among vulnerable populations, thereby promoting well-being and quality of life.

Underfloor Insulation
Building Regulations

In Edinburgh, just like in any other part of the UK, adherence to specific building regulations is crucial, especially when it involves the installation of underfloor insulation and the upgrading of flooring.

Guidelines outlined in the Building Standards 2017 offer comprehensive insights into meeting the required standards concerning insulation and flooring. These standards are intricately designed to enhance energy efficiency and bolster the insulation envelope of buildings.

Scotland’s Building Standards are particularly focused on minimizing heat loss and elevating the energy efficiency levels of all structures, aligning seamlessly with overarching UK directives.

For instance, in Scotland, the U-value, which denotes the thermal performance standard of an upgraded floor, must not exceed 0.18 W/m2K. Contrarily, in England, Wales, and Northern Ireland, the U-value should stand at a minimum of 0.25 W/m2K. This contrast highlights Scotland’s stringent commitment to energy efficiency, setting a high standard for sustainable building practices.

How Much Could You Save A Year?

While professional underfloor insulation services in Edinburgh may come with a price tag ranging from £300 to £3,000, particularly for larger properties, there’s an opportunity to obtain free underfloor insulation through the ECO4 scheme. The program offers the benefit of insulating solely the ground floor, reducing both costs and energy usage.

Implementing underfloor insulation can lead to substantial savings on your yearly energy expenses. Data from the Energy Saving Trust indicates that, on average, you can anticipate the following annual savings:

• 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.


Yes, you have the flexibility to select the professional who installs your insulation. However, it’s crucial to ensure that the chosen installer is trade-registered, approved, and authorized under the ECO scheme to carry out the work. While there’s room for choice, the options may be limited to those certified to maintain the program’s standards and regulations.

Underfloor insulation installation is efficient and leaves minimal mess. Upon qualification, you’ll be provided with a scheduled date for the installer’s visit to your residence. The duration of installation typically ranges from a few days to completion, contingent upon factors such as property size and the accessibility of the underfloor area. Additionally, for urgent situations, emergency services are available, capable of completing the installation within a single day.
