Insulating your home is one of the most effective ways to improve energy efficiency, lower heating bills, and enhance comfort. But when it comes to choosing between underfloor insulation and loft insulation, homeowners often wonder which option will provide the best results.
Both insulation types play a crucial role in preventing heat loss, but the right choice depends on your home’s structure, budget, and specific insulation needs. In this guide, we’ll compare underfloor vs. loft insulation, helping you decide which one is best for your property.
What is Loft Insulation?
Loft insulation is installed in the roof space of your home, typically in the form of insulation rolls, boards, or spray foam. Since up to 25% of heat is lost through the roof, insulating your loft significantly improves thermal efficiency.
Benefits of Loft Insulation:
- Reduces heat loss – Keeps warmth inside during winter and prevents overheating in summer.
- Lowers energy bills – Can save homeowners up to £500 per year in heating costs.
- Quick installation – A standard loft insulation job can be completed within a day.
- Long-lasting solution – Insulation lasts 40+ years, making it a great long-term investment.
- Eco-friendly option – Available in sustainable materials like sheep’s wool and recycled materials.

What is Underfloor Insulation?
Underfloor insulation is installed beneath floorboards or between floor joists, helping to trap heat inside your home. This type of insulation is particularly effective in older properties with suspended timber floors, which can be prone to cold drafts.
Benefits of Underfloor Insulation:
- Eliminates cold floors – No more freezing feet on winter mornings!
- Reduces heat loss – Prevents warmth from escaping through the ground.
- Improves comfort – Helps maintain an even temperature throughout your home.
- Energy savings – Can reduce heating costs by up to 15% per year.
- Compatible with other insulation – Works well alongside loft and wall insulation for maximum efficiency.

FAQs About Underfloor & Loft Insulation
1. Can I have both loft and underfloor insulation?
Absolutely! Many homeowners combine both insulation types to achieve better energy efficiency and comfort.
2. Which insulation type offers the biggest savings?
Loft insulation typically saves more energy because heat naturally rises, but underfloor insulation is essential for reducing drafts and cold floors.
3. How long does insulation last?
Most insulation materials last 40+ years with proper installation, offering a long-term return on investment.
4. Is underfloor insulation worth it for newer homes?
Newer homes with solid concrete floors may not require underfloor insulation, but it’s beneficial for timber or suspended floors.
5. What insulation materials do you use?
We use high-performance materials like Knauf insulation, natural wool, and eco-friendly options to provide the best results.
