Loft insulation is crucial for energy efficiency and comfort in homes across the UK. With rising energy costs, homeowners increasingly look for effective ways to reduce their heating bills and carbon footprints. The UK government considers loft insulation an energy-saving material and offers VAT relief for its installation. From April 2022 to 31st March 2027, the installation of loft insulation benefits from a zero rate of VAT, highlighting its role in promoting energy efficiency.
One common concern is loft insulation's fire safety. While not entirely fireproof, the best loft insulation materials are designed to be fire-resistant, offering significant protection. Choosing the right insulation can enhance home safety while providing energy savings and improved comfort.

Loft insulation in the UK is generally fire-resistant but not completely fireproof. Here are the key points regarding its fire safety:
Smoke Production (s1, s2, s3) measures how much smoke a burning material makes, with s1 being the least and s3 the most. Flaming Droplets/Particles (d0, d1, d2) checks if burning material releases fiery drops that can spread fire, with d0 meaning no drops and d2 the most drops
While mineral wool and fibreglass are highly fire-resistant, they are not entirely fireproof. Proper installation and adherence to building regulations are essential for optimal fire safety. Always consult professionals when installing or upgrading loft insulation.
The European Reaction to Fire Classification System (Euroclasses) is a standardised method for assessing the fire performance of construction materials across EU member states, including the UK.
Here's a summary:
The Euroclasses standardised testing of materials is crucial in ensuring fire safety during construction and insulation upgrades, including materials for loft insulation.
Here’s a summary of the main fire ratings for the most popular loft insulation materials, raging from A1 (best) to F (worst):
When considering whether loft conversion insulation is fireproof, it's important to recognise the factors influencing its flammability. Here’s a summary:
How much difference does loft insulation make? Loft insulation is a beneficial choice for UK homes, offering significant advantages in energy efficiency, with potential savings of up to £345 annually for a detached house, with the cost of loft insulation installation being around £930, the availability of loft insulation grants, and CO2 savings of 620 kg per year. This makes it a highly affordable option to improve your home’s energy efficiency and temperature comfort.
Loft insulation improves temperature consistency, reduces noise, and is a long-term investment. Given its benefits and fire-resistant properties, it's highly recommended for UK homes. However, proper installation and adherence to building regulations are crucial for maximum safety and efficiency.

Loft insulation materials like mineral wool and fibreglass are generally highly fire-resistant but not completely fireproof.
No insulation material is completely fireproof, but some offer high fire resistance. Mineral wool, for example, achieves the highest fire safety rating (Euroclass A1), making it non-combustible and able to withstand temperatures over 1000°C without melting.
Fibreglass loft insulation is not completely fireproof but is highly fire-resistant. It typically achieves an A1 or A2 Euroclass rating, indicating excellent fire resistance without significant contribution to fire growth.
