FREE Underfloor

Free Underfloor Insulation Grants Lothians

In Lothians, many homeowners focus on insulating walls and roofs for energy efficiency but overlook the significant heat loss through uninsulated floors. Even with existing insulation, up to 20% of a home’s heating can escape through the floor. Investing in floor insulation, though it can cost up to £3,000 for larger homes, offers long-term benefits such as reduced heating bills and enhanced energy efficiency. To support this effort, the Scottish government provides grants through the Energy Company Obligation (ECO) scheme, making underfloor insulation more accessible to homeowners in Lothians.

In the pursuit of aligning with international commitments to curb carbon emissions, the ECO scheme stands as a pivotal initiative aimed at enhancing Scotland’s energy efficiency landscape. Under this scheme, significant energy corporations allocate funds to bolster the energy efficiency of residences, thereby contributing to the overarching goal of reducing the country’s carbon footprint.

Within the framework of the ECO4 scheme, succeeding the ECO3 scheme in 2022 and extending until 2026, alongside the Affordable Warmth Obligation component, qualifying individuals stand to benefit from subsidized energy-saving interventions. Notably, one such provision includes the installation of underfloor insulation, which holds the potential to ameliorate heat loss within domiciles by up to 15%.

Eligibility for the underfloor insulation grant is contingent upon specific criteria, ensuring equitable distribution of resources. Homeowners, owner-occupiers, or tenants, with requisite consent from landlords, are eligible beneficiaries poised to reap the rewards of this initiative.

Why apply for the underfloor insulation grant?

Homeowners with wooden or suspended floors have the opportunity to benefit from complimentary underfloor insulation, provided they meet specific eligibility requirements. Upon approval, certified installers will visit your residence to seamlessly integrate the insulation, enhancing heat retention within your home. This initiative not only diminishes energy expenses but also fosters a cosier living environment.

Investing in underfloor insulation independently can be financially burdensome, often amounting to substantial costs. However, through this program, recipients are relieved of any financial obligations while reaping the rewards of improved insulation and warmer flooring.

It’s crucial to note that the ECO4 scheme, facilitating such insulation grants, is slated to conclude on March 31, 2026. After this deadline, alterations to eligibility criteria or grant availability may occur. Seizing this opportunity while it’s accessible is prudent, ensuring maximum benefit from the available grants.

Do You Qualify
For Free Underfloor Insulation?

Qualifying for free floor insulation in Lothians is subject to specific criteria that must be met.

Homes constructed during or after the 1980s typically do not meet the eligibility requirements. This is because older homes featured wooden floors, whereas contemporary constructions integrate solid concrete ground floors.

However, if your residence includes a basement or is situated on a slope with a crawlspace beneath the ground floor, you may be eligible for the grant. Essential criteria include at least one meter of headroom beneath the floor and accessibility via a hatch.

Additionally, a minimum of two-thirds of the home’s footprint must be available for underfloor insulation installation to qualify for the grant.

Furthermore, homeowners who previously had underfloor insulation installed may have the opportunity to upgrade using modern 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 dwelling is compatible with every type of insulation. Even if your residence is suitable for wall or loft insulation, underfloor insulation necessitates specific conditions.

Residences equipped with cellars, basements, or underfloor crawlspaces generally accommodate underfloor insulation, provided there’s approximately one meter of clearance beneath the floor.

Suspended timber floors, prevalent in many older homes, lend themselves well to 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.

Dwellings 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. Owners of such properties may be eligible for complimentary underfloor insulation.

Installing floor insulation under a suspended floor in Lothians involves laying insulating mineral fiber beneath the visible floorboards and securing it with netting fastened to the joists. Alternatively, spray foam presents a contemporary solution, expanding and adhering to the underside of wooden floors to retain heat in the room above.

However, it’s important to note that installing floor insulation is not feasible for concrete floors in Lothians, as there is no space underneath. Instead, concrete floors are insulated by applying insulation layers on top.

The Advantages
Of Underfloor Heating

Ensuring your home remains cozy and energy-efficient encompasses more than just typical insulation methods like wall insulation and double-glazed windows. Underfloor insulation is a crucial component in regulating indoor temperatures and offers various additional advantages, particularly in Lothians, a region where weather fluctuations can be pronounced.

Improved thermal efficiency

Efficient thermal insulation is vital for homes in Lothians to maintain warmth during chilly seasons and keep cool during hot spells. Underfloor insulation plays a pivotal role in achieving this, significantly reducing heat loss through the floor and ensuring a comfortable living environment all year round.

Mess-free installation

Underfloor insulation offers a hassle-free installation process, with all work conducted discreetly beneath the floorboards and between the joists. This method ensures no disruption to daily household activities, leaving the ground floor clean and unaffected.

Reduced heating bills

With better thermal efficiency comes the added bonus of reduced energy usage. As homes are able to retain heat better, heating systems won’t have to work as hard to maintain a consistent, comfortable temperature in the home.

Homeowners with underfloor insulation will have reduced energy bills because of less heat loss and more stable temperatures in the house.

Although less of a concern in the cooler Scottish climate, airconditioning units will also have to work less to cool down a house during summer. Less of the outside heat will be able to penetrate the floor.

No need to redesign your floors

Unlike extensive renovations to timber flooring, underfloor insulation requires no major structural changes. Installation can proceed seamlessly without the need for floor redesign, making it a convenient and cost-effective choice for homeowners seeking to enhance thermal efficiency.

Enhanced comfort

Underfloor insulation not only ensures a consistently comfortable indoor temperature but also adds value to properties in Lothians.

Increased house value

Energy-efficient homes are highly sought after in the real estate market, making properly insulated properties more attractive to potential buyers.

Reduced condensation

In Lothians’ climate, uninsulated floors are susceptible to condensation and mould growth due to fluctuating temperatures. Underfloor insulation mitigates this risk by maintaining warmer floor surfaces, thus preventing moisture-related issues.

Noise reduction

Insulation also offers soundproofing benefits, particularly in basements or multi-storey homes, where it minimizes noise transmission between floors.

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 home contributes to the overall health and well-being of its occupants, especially vulnerable populations. By creating a comfortable living environment with stable temperatures, underfloor insulation helps mitigate health risks associated with cold, draughty conditions, emphasizing the importance of initiatives such as the ECO4 underfloor insulation grant in Lothians.

Underfloor Insulation
Building Regulations

In Lothians, adherence to specific building regulations is imperative when undertaking underfloor insulation installation and flooring upgrades in the United Kingdom.

Guidelines outlined in the Building Standards 2017 are pivotal for ensuring compliance with insulation and flooring standards. These directives are primarily aimed at enhancing energy efficiency and fortifying the building’s insulation envelope.

Scotland’s Building Standards prioritize the minimization of heat loss and the enhancement of energy efficiency across all structures. These standards align closely with the broader UK regulations.

In Scotland, the thermal performance standard, represented by the U-value of an upgraded floor, must not exceed 0.18 W/m2K. Conversely, in England, Wales, and Northern Ireland, the U-value should be no less than 0.25 W/m2K. This divergence underscores Scotland’s commitment to stringent energy efficiency measures.

How Much Could You Save A Year?

In Lothians, professional underfloor insulation services may come with a price tag ranging from £300 to £3,000 for larger properties. However, individuals residing in this area can benefit from free underfloor insulation under the ECO4 scheme. It’s worth noting that only insulating the ground floor is required.

Implementing this insulation solution brings about substantial savings on yearly energy expenses. Figures from the Energy Saving Trust indicate potential annual savings, averaging:

• 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 choose who installs your insulation. However, it’s crucial that the installer is trade-registered, approved, and authorized to perform the work under the ECO scheme. While there’s some flexibility in choosing, your options are limited to those who meet these criteria.

Underfloor insulation installation is efficient and minimally disruptive. Upon qualification, you’ll receive a scheduled installation date. Typically, installation can be completed within a few days, varying based on property size and underfloor accessibility. Additionally, there are emergency services available for rapid installation, completing the process within a day if needed.
