Attic Insulation Cost Overview: What to Expect
When considering attic insulation, it's important to understand the typical costs involved. The cost to insulate an attic varies based on factors such as the size of the attic, the insulation material used, and the complexity of the installation.
On average, attic insulation costs in the UK range from $1,500 to $3,000, including materials and installation. These costs can offer substantial savings in the long run by improving your home’s energy efficiency.

Types of Attic Insulation: Costs and Considerations
There are several types of attic insulation available, each with its own benefits and costs. Understanding these options will help you make an informed decision about which type suits your home and budget.
Below is a breakdown of common attic insulation types and their costs:
| Insulation Type | Cost per Square Foot |
|---|---|
| Fibreglass | $0.40 – $2.00 |
| Cellulose | $0.60 – $2.30 |
| Spray Foam | $2.50 – $8.00 |
Blown-in attic insulation cost is typically lower compared to spray foam, and it is an effective option for insulating irregular spaces.
Spray foam attic insulation is more expensive but provides superior air sealing and better thermal performance. Depending on your home’s needs, the initial higher cost of spray foam insulation can be offset by long-term savings on energy bills.

Additional Costs to Consider: Hidden Expenses in Attic Insulation
While insulating your attic, there are several hidden costs that may arise. These additional expenses can affect the overall project budget, so it’s essential to account for them early on.
Air Sealing and Ventilation:
Before installing insulation, air sealing and proper ventilation may be necessary to optimise insulation performance. These services could add $350 to $1,500 to your total costs.
Removal of Old Insulation:
If your attic contains outdated or damaged insulation, removal can add to the labour cost and increase the overall project timeline.
Permits and Unexpected Repairs:
Depending on your location, you may need permits for the installation, adding extra costs. Furthermore, unexpected issues like structural damage or pest infestations may require additional repairs.

FAQ: Common Questions Readers Ask About Attic Insulation Costs
What is the estimated attic insulation cost per square foot for different insulation materials?
The cost per square foot varies by material: Fibreglass batts typically cost between $0.30 and $1.50, blown-in cellulose ranges from $1 to $2, and spray foam costs between $3 and $5. Reflective or radiant barrier insulation costs around $0.50 to $1.50 per square foot.
How does the process of installing spray foam attic insulation affect the total cost?
Spray foam installation is more complex and requires professional expertise. Closed-cell spray foam offers high R-value and durability, but its labour-intensive application increases the total cost. The price depends on the thickness applied and the accessibility of the area.
What are the potential savings on energy bills that come with effective attic insulation?
Effective attic insulation can reduce heating and cooling costs by up to 20% or more annually. Improved thermal efficiency means less energy is needed to maintain desired temperatures, leading to lower utility bills.
What challenges might arise during attic insulation installation that could impact costs?
Challenges such as limited access to certain attic areas, the need for existing insulation removal, or unexpected repairs (e.g., leaks or mould issues) can increase both labour and material costs. Attic obstructions can also complicate installation and raise expenses.
How does the size and layout of my attic affect the insulation cost?
The size and layout of your attic affect the cost, as larger areas require more materials and possibly more labour. Attics with complex features, such as vaulted ceilings or numerous nooks, can make installation more challenging and expensive compared to a standard open layout.
