Loft room insulation is an essential upgrade for any home, offering a range of benefits from improved comfort to significant savings on energy bills. With so many insulation options available, it can be hard to know where to start. This guide will break down the different types of loft room insulation, their costs, and the long-term benefits they provide. Additionally, we’ll explore how loft insulation grants and free loft insulation options can make this upgrade more affordable.
What Is Loft Room Insulation?
Loft room insulation is the material used to reduce the transfer of heat between the interior of your home and the attic or loft space. This insulation helps trap warm air inside during the colder months and prevents cool air from escaping in the warmer months. By doing so, it improves the energy efficiency of your home, keeping it comfortable year-round.
Beyond improving comfort, loft room insulation can also significantly reduce your energy consumption. According to the Energy Saving Trust, about 25% of heat in an uninsulated home is lost through the roof. By insulating your loft, you can cut this loss and keep your home warmer, all while saving money on your heating bills.
Types of Loft Room Insulation
When it comes to choosing loft room insulation, several materials are available. Each type offers unique advantages, so it’s important to consider which one suits your needs and budget.
Fiberglass Loft Insulation
Fiberglass insulation is one of the most popular and cost-effective options for loft room insulation. This material comes in rolls or batts, which can be easily installed between the joists of your loft.
Benefits
● Cost-effective: Fiberglass is one of the least expensive insulation options, making it ideal for homeowners on a budget.
● Effective heat retention: It provides great thermal resistance and reduces heat loss.
● Easy to install: For DIYers, fiberglass insulation is relatively easy to install, but it’s always better to seek professional help for a more efficient and safe installation.
Considerations
Fiberglass can irritate the skin and lungs during installation, so it's crucial to wear protective clothing and a mask. Over time, fiberglass insulation can also sag or settle, reducing its efficiency.
Spray Foam Loft Insulation
Spray foam insulation is applied as a liquid that expands into a solid foam when sprayed into place. This insulation is ideal for filling gaps and providing an airtight seal.
Benefits
● Air barrier: Spray foam offers excellent air sealing, preventing drafts and heat loss from even the smallest gaps.
● High performance: It provides a high R-value (a measure of thermal resistance), which means it is very effective at insulating your loft room.
● Moisture resistant: It helps reduce the risk of condensation, which can lead to mould and mildew growth.
Considerations
Spray foam insulation is more expensive than fiberglass. Installation must be carried out by a professional to ensure it is applied correctly.
Cellulose Loft Insulation
Cellulose insulation is made from recycled paper products, which are treated with a fire retardant to make it safe for use in your home. This eco-friendly option is often used for blown-in insulation.
Benefits
● Eco-friendly: Cellulose is made from recycled materials, making it an environmentally friendly option.
● Good for soundproofing: It’s excellent at absorbing sound, making it ideal if you want to reduce noise from your loft room.
● Good thermal performance: Cellulose offers a higher thermal resistance than some other types of insulation.
Considerations
It can settle over time, which reduces its effectiveness unless it is installed with a high density. Professional installation is required for blown-in cellulose insulation.

Loft Room Insulation Costs
The cost of installing loft room insulation will vary depending on several factors, including the size of the loft, the type of insulation used, and whether you hire a professional or install it yourself. Things that might impact your loft room insulation costs include:
Loft Size - Larger lofts require more insulation material and longer installation times, increasing the overall cost.
Type of Insulation - As mentioned, spray foam tends to be the most expensive option, while fiberglass is one of the more affordable choices.
Installation Labour - Professional installation adds to the cost, though it ensures the job is done correctly.
Estimated Costs
● Fiberglass Insulation: Typically costs between £300 and £700 for professional installation in a standard-sized loft. DIY installation will save on labour costs but may be challenging for large lofts.
● Spray Foam Insulation: The price for spray foam insulation can range from £1,000 to £2,500, depending on the size of your loft. While more expensive, it provides a highly effective air barrier.
● Cellulose Insulation: Installing cellulose insulation typically costs between £400 and £900. It is slightly more expensive than fiberglass but offers good soundproofing and thermal properties.
Benefits of Loft Room Insulation
There are several benefits to having loft room insulation installed. Some of these benefits include:
Improved Comfort
Loft insulation helps maintain a consistent temperature in your home, which is essential for comfort. Without proper insulation, you may experience drafts, making it harder to keep your loft warm in winter or cool in summer. By insulating your loft, you'll prevent heat loss and keep the space more comfortable year-round.
Reduced Heat Loss
Up to 25% of your home's heat can be lost through an uninsulated roof. Loft room insulation helps reduce this loss, ensuring that more of the heat generated by your heating system stays inside your home. This reduction in heat loss makes your home more energy-efficient and lowers the demand on your heating system.
Energy Efficiency
With proper insulation, your home becomes more energy-efficient, meaning you’ll use less energy to heat your home. This not only lowers your utility bills but also reduces your carbon footprint. By cutting your heating costs, loft insulation helps you save money while benefiting the environment.
Increased Property Value
Homes with loft room insulation tend to be more appealing to potential buyers because they offer lower running costs and better comfort. This energy-efficient upgrade can increase the value of your home, making it more competitive in the market.
Loft Insulation Grants and Free Loft Insulation: Eligibility for Loft Insulation Grants
One of the most significant advantages of installing loft room insulation is the availability of loft insulation grants. The UK government, in partnership with local authorities and energy providers, offers grants to eligible homeowners to help cover the costs of insulation. These grants are designed to assist those on low income or living in energy-inefficient homes.
● Who Qualifies for Loft Insulation Grants?
● Low-income households
● Pensioners
● Disabled individuals
● Households receiving certain government benefits (e.g., Universal Credit or Pension Credit)
How to Apply for Loft Insulation Grants
The first step is to check your eligibility. Various websites and local councils offer information on the application process. You can also inquire with loft insulation companies that participate in government schemes to see if they offer free loft insulation.
