FREE Underfloor

Free Underfloor Insulation Grants Shetland

In Shetland, many homeowners diligently address energy efficiency concerns by insulating their walls and roofs. However, often overlooked is the significant heat loss that occurs through the floor. Even with cavity or solid wall insulation in place, homes can still lose up to 20% of their heating through uninsulated floors.

Recognizing the importance of comprehensive insulation, investing in floor insulation emerges as a prudent choice. While the upfront cost can reach up to £3,000 for larger properties, the long-term benefits outweigh this initial expense.

Underfloor insulation presents a non-invasive solution that not only enhances the warmth of your home but also reduces heating expenses and contributes to overall energy efficiency. To further incentivize this eco-conscious investment, the Scottish government extends support through grants available via the Energy Company Obligation (ECO) scheme. This initiative aims to make energy-saving measures more accessible and affordable for homeowners in Shetland and beyond.

The ECO initiative plays a pivotal role in aligning with Scotland’s commitment to reducing its carbon footprint on a global scale. Spearheaded by major energy corporations, this scheme mandates the allocation of funds towards enhancing the energy efficiency of residential properties. Eligible participants stand to benefit from energy-saving measures financed by these designated funds.

Under the umbrella of the ECO4 scheme, which succeeded its predecessor, ECO3, in 2022 and remains effective until 2026, along with the Affordable Warmth Obligation component, qualifying individuals have the opportunity to receive complimentary installation of underfloor insulation. Meeting specific eligibility criteria is paramount for availing oneself of this advantageous provision.

Implementing underfloor insulation beneath wooden or suspended timber floors can significantly mitigate heat loss within homes, potentially reducing it by up to 15%. This initiative extends its reach to homeowners, owner-occupiers, or tenants, provided they secure consent from the property owner or landlord.

Why apply for the underfloor insulation grant?

Residents of Shetland with wooden or suspended floors have the opportunity to receive complimentary underfloor insulation, subject to meeting eligibility requirements. Upon approval, certified installers will visit your home to seamlessly install the insulation. This initiative aims to enhance heat retention within households, leading to decreased energy expenditures and heightened comfort levels.

Purchasing underfloor insulation privately can entail substantial expenses, often amounting to thousands of pounds. However, through this scheme, participants are relieved of any financial burden while reaping the advantages of enhanced warmth and energy efficiency.

It’s crucial to note that the ECO4 scheme is slated to conclude on March 31, 2026. After this deadline, eligibility criteria or the availability of grants may undergo alterations. Therefore, it’s advisable to capitalize on these opportunities while they persist.

Do You Qualify
For Free Underfloor Insulation?

Not every household in Shetland will meet the eligibility criteria for complimentary floor insulation. Specific requirements need to be fulfilled.

Houses constructed during or post the 1980s are typically ineligible due to the prevalence of solid concrete ground floors in modern constructions. Conversely, older homes often feature wooden floors, rendering them more suitable candidates.

Residents with basements or properties built on inclines, featuring a crawlspace beneath the ground floor, might be eligible for the subsidy. A minimum headroom clearance of one meter beneath the floor, along with access through a hatch, is necessary.

Additionally, at least two-thirds of the property’s footprint must be accessible for the installation of underfloor insulation.

Those who previously installed underfloor insulation might still qualify for an update utilizing contemporary insulation 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 home is equally conducive to all forms of insulation. While wall or loft insulation may be viable for some, underfloor insulation necessitates specific conditions.

Properties in Shetland with cellars, basements, or crawlspaces beneath the floor generally lend themselves well to underfloor insulation, provided there’s approximately a meter of headroom below the floor.

Older properties often feature suspended timber floors, which are prime candidates for insulation. These floors not only suffer heat loss but also offer ample space for insulation installation. Typically, suspended timber ground floors consist of floorboards resting on joists above an accessible space.

Homes in Shetland equipped with air bricks or ventilation bricks in the exterior walls below the damp-proof membrane on the ground floor tend to experience significant heat loss. Such properties may be eligible for complimentary underfloor insulation services.

Installing floor insulation beneath suspended floors in Shetland involves placing insulating mineral fiber below the exposed floorboards and securing it with netting fastened to the joists. An alternative method is employing spray foam, which expands and adheres to the underside of wooden floors, effectively retaining heat in the room above.

However, it’s essential to note that installing floor insulation beneath concrete floors in Shetland is not feasible 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 insulation.

The Advantages
Of Underfloor Heating

Ensuring a cozy and sustainable household extends beyond basic measures like wall insulation and double-glazed windows. Underfloor insulation, particularly in regions like Shetland, holds significant importance in regulating indoor temperatures and offers a range of additional advantages:

Improved thermal efficiency

Maximizing thermal efficiency is crucial for homes in Shetland, where chilly weather prevails. Underfloor insulation plays a pivotal role in this endeavor by curbing heat loss through suspended timber floors. By combining underfloor, wall, and loft insulation, residences can significantly enhance energy efficiency, retaining warmth even amidst the coldest spells. Conversely, during scorching days, underfloor insulation acts as a barrier, preventing excessive heat from infiltrating interiors.

Mess-free installation

Underfloor insulation installation is a hassle-free endeavor, sparing homeowners from disruptions. The process occurs seamlessly beneath the floorboards, nestled between joists, ensuring no mess or inconvenience on the ground level. Household routines remain undisturbed, making the insulation installation a seamless addition to home improvement efforts.

Reduced heating bills

The benefits of underfloor insulation extend beyond mere energy efficiency, translating into tangible cost savings. With reduced heat loss, homes demand less energy for heating, thereby slashing utility bills. Moreover, maintaining a consistent, comfortable temperature year-round enhances living conditions, particularly during the harsh winters in Shetland.

No need to redesign your floors

For owners of older homes, concerns about preserving architectural integrity often arise when contemplating insulation upgrades. However, underfloor insulation eliminates the need for extensive renovations. Retrofitting insulation beneath existing floors circumvents the need for floor redesigns, preserving the charm of traditional timber flooring while boosting thermal efficiency.

Enhanced comfort

Having insulation installed underneath your floors will ensure your house is always at a comfortable temperature. Cold, draughty floors can be very uncomfortable, especially in winter. Insulation will ensure no cold air enters through old floorboards.

Increased house value

In the competitive real estate market, energy-efficient properties command a premium. By investing in comprehensive insulation measures, including underfloor insulation, homeowners in Shetland can bolster their property’s value. Prospective buyers are increasingly drawn to residences equipped with energy-saving features, making insulation upgrades a wise investment.

Reduced condensation

In Shetland’s damp climate, uninsulated floors are prone to condensation, fostering mold growth and compromising indoor air quality. Underfloor insulation mitigates this risk by maintaining warmer floor surfaces, curbing condensation-related issues.

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

Health benefits are substantial, as stable indoor temperatures promote well-being, particularly among vulnerable populations susceptible to cold-related ailments.

Underfloor Insulation
Building Regulations

In Shetland, adherence to building regulations regarding underfloor insulation and flooring upgrades is crucial. Governed by the Building Standards 2017, these regulations are designed to enhance energy efficiency and minimize heat loss within structures.

Scotland’s Building Standards are particularly stringent in their approach to energy conservation. With a primary focus on improving the energy efficiency of buildings, these standards are aligned with UK guidelines but tailored to Scottish requirements.

One key metric used to gauge thermal performance is the U-value. In Shetland and across Scotland, the U-value for upgraded floors must not exceed 0.18 W/m2K. This standard surpasses that of England, Wales, and Northern Ireland, where a minimum U-value of 0.25 W/m2K is acceptable.

By ensuring compliance with these regulations, structures in Shetland can effectively mitigate heat loss and contribute to overall energy efficiency, thereby aligning with broader environmental conservation goals.

How Much Could You Save A Year?

In Shetland, homeowners can access free underfloor insulation through the ECO4 program, eliminating the need for hefty upfront costs that can range from £300 to £3,000 for larger properties. This initiative specifically targets ground floor insulation, ensuring efficient energy use and cost savings.

Installing underfloor insulation not only qualifies homeowners for the ECO4 program but also leads to substantial reductions in annual energy expenses. Based on data from the Energy Saving Trust, households can anticipate average annual savings, including:

• 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.


Absolutely, you have the freedom to choose who handles your insulation installation.
