FREE Underfloor

Free Underfloor Insulation Grants Perthshire

Many homeowners focus on insulating their walls and roofs for better energy efficiency, often overlooking the significant heat loss that can occur through uninsulated floors. Even with well-insulated walls, up to 20% of a home’s heating can escape through the floor.

Investing in floor insulation is a practical step towards reducing heat loss and energy bills. While the upfront costs, which can reach £3,000 for larger homes, may seem daunting, the long-term benefits are undeniable.

Underfloor insulation presents a non-invasive solution that can effectively warm up your living space, decrease heating expenses, and enhance overall energy efficiency. Recognizing the importance of such measures, the Scottish government is supporting homeowners by offering grants for underfloor insulation through the Energy Company Obligation (ECO) scheme. These grants aim to encourage more sustainable and energy-efficient practices in homes across Perthshire and beyond.

The ECO scheme aims to help Scotland reduce its carbon footprint. Major energy companies must allocate funds to improve home energy efficiency. Eligible individuals can have energy-saving measures funded through this scheme.

The ECO4 scheme, replacing ECO3 in 2022 and running until 2026, along with the Affordable Warmth Obligation, offers free underfloor insulation installation to eligible residents in Perthshire.

Underfloor insulation, installed under wooden or suspended timber flooring, can reduce heat loss by up to 15%. Homeowners, owner-occupiers, or tenants with landlord permission can apply for the grant.

Why apply for the underfloor insulation grant?

In Perthshire, homeowners with wooden or suspended floors have the opportunity to receive complimentary underfloor insulation, provided they meet specific eligibility criteria. Upon approval, certified installers will visit your residence to install the insulation, enhancing heat retention and ultimately reducing energy expenses while fostering a cosier living environment.

Investing in underfloor insulation privately can be financially burdensome, often costing thousands of pounds. However, through this scheme, recipients incur no repayment obligations while reaping the rewards of improved insulation and warmer flooring.

The ECO4 scheme remains accessible until March 31, 2026, after which the criteria or availability of grants may undergo alterations. Seizing the current opportunity to benefit from these grants is advisable to maximize household comfort and energy efficiency.

Do You Qualify
For Free Underfloor Insulation?

Not every household in Perthshire will meet the criteria for receiving free floor insulation. Specific qualifications must be met to be eligible for this assistance.

Homes constructed during or after the 1980s are generally ineligible for free floor insulation. This is primarily due to the shift from wooden floors in older homes to solid concrete ground floors in more modern constructions.

However, if your residence includes a basement or is situated on a slope with a crawlspace beneath the ground floor, you might still qualify for the grant. Essential requirements include a minimum of one meter of headroom beneath the floor and access provided through a hatch.

Furthermore, to be considered for underfloor insulation, at least two-thirds of the home’s footprint must be available for installation purposes.

For those who have previously had underfloor insulation installed, there may be opportunities to update it using modern insulation materials, potentially extending the benefits of insulation to more households in the area.

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 residences are compatible with every type of insulation. Even if your home is well-suited for wall or loft insulation, underfloor insulation demands its own set of prerequisites.

Properties equipped with cellars, basements, or underfloor crawlspaces generally accommodate underfloor insulation, provided there’s roughly a meter of clearance beneath the floor.

Suspended timber floors, commonly found in older dwellings, are conducive to insulation. These floors not only dissipate significant heat but also offer ample space for insulation installation. Such floors consist of floorboards resting atop joists over an empty space.

Domiciles featuring air bricks or ventilation bricks in the exterior walls below the damp-proof membrane on the ground floor often experience substantial heat loss. These residences may qualify for complimentary underfloor insulation.

Installing floor insulation under a suspended floor in Perthshire involves laying insulating mineral fibre beneath exposed floorboards, secured with netting attached to joists. Alternatively, spray foam offers a modern solution by adhering to the underside of wooden floors, effectively trapping heat in the room above.

For concrete floors in Perthshire, traditional floor insulation methods aren’t feasible due to the absence of space beneath the concrete. Instead, insulation is applied on top of the concrete floors to achieve thermal efficiency.

The Advantages
Of Underfloor Heating

Ensuring your home remains cozy and energy-efficient involves more than mere wall insulation and double-glazed windows. The inclusion of underfloor insulation significantly contributes to sustaining a comfortable temperature within your residence while offering additional advantages:

Improved thermal efficiency

Underfloor insulation is a practical solution to bolstering the thermal efficiency of homes in Perthshire. By preventing heat loss through the suspended timber floors, coupled with wall and loft insulation, residences become more energy-efficient, maintaining warmth even during the chilliest months. Conversely, on hot days, this insulation ensures homes remain cool by impeding the influx of heat through flooring gaps.

Mess-free installation

Installing underfloor insulation is a hassle-free endeavor, causing minimal disruption. As the insulation is fitted beneath the floorboards between the joists, there’s no mess on the ground floor, allowing household activities to continue uninterrupted.

Reduced heating bills

The benefits extend to reduced heating bills, as enhanced thermal efficiency diminishes energy consumption. With heating systems requiring less effort to sustain a comfortable indoor temperature, homeowners enjoy cost savings over time.

No need to redesign your floors

Unlike extensive renovations, underfloor insulation eliminates the need for redesigning timber flooring in older homes. The insulation materials can be seamlessly integrated beneath the floor without major construction work. Additionally, for properties with existing insulation, grants cover upgrades to modern, more effective materials.

Enhanced comfort

Underfloor insulation guarantees year-round comfort, shielding homes from cold draughts and maintaining stable temperatures.

Increased house value

Energy-efficient homes are in high demand in the real estate market. By properly insulating your home, including the floor, loft and wall, you increase the value of your property. It will be more attractive to potential buyers.

Reduced condensation

In Perthshire’s climate, uninsulated floors are susceptible to condensation and mould growth due to temperature differentials. Underfloor insulation mitigates this risk by maintaining warmer floor surfaces. 

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

A well-insulated, comfortable home contributes to the overall health and well-being of its occupants. By eliminating cold, draughty environments prone to dampness, underfloor insulation helps prevent diseases, especially among vulnerable populations. The availability of grants, such as the ECO4 program, underscores the importance of ensuring homes are conducive to good health and well-being.

Underfloor Insulation
Building Regulations

In Perthshire, like in many parts of the UK, adhering to building regulations is paramount, especially when it comes to underfloor insulation and flooring upgrades.

The Building Standards 2017 offer clear directives on meeting insulation and flooring standards, with a primary focus on enhancing energy efficiency and fortifying the building’s insulation envelope. These guidelines are designed to align closely with UK regulations, ensuring consistency and efficacy across the country.

Scotland’s Building Standards are particularly stringent in their aim to reduce heat loss and bolster energy efficiency in all structures. For instance, the prescribed U-value (a measure of thermal performance) for upgraded flooring in Scotland stands at no worse than 0.18 W/m2K. In comparison, England, Wales, and Northern Ireland mandate a U-value of at least 0.25 W/m2K for similar upgrades. This highlights Scotland’s robust commitment to advancing energy efficiency standards.

How Much Could You Save A Year?

In Perthshire, investing in professional underfloor insulation can range from £300 to £3,000 for larger properties. However, residents can explore the option of obtaining free underfloor insulation through the ECO4 scheme, which specifically targets ground floor insulation.

The installation of underfloor insulation can lead to substantial savings on energy bills annually. According to data from the Energy Saving Trust, the average household can anticipate significant cost reductions, 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.


Yes, you have the freedom to select the installer for your insulation needs. However, it’s imperative that the chosen installer is trade-registered, approved, and authorized to carry out the work under the ECO scheme guidelines. While you maintain some discretion in the selection process, your choices are restricted to those who meet the necessary qualifications and standards.

Underfloor insulation installation is characterized by its efficiency and minimal disruption. Upon qualification, you’ll be provided with a scheduled installation date. The duration of installation typically ranges from a few days to complete, contingent upon factors such as property size and accessibility to the underfloor area. Additionally, emergency services are available for expedited installations, completing the process within a single day if necessary.
