Loft Insulation Grants 2025 – Save Money, Reduce Heat Loss & Increase Comfort
Did you know that up to 25% of a home’s heat escapes through the roof if the loft is not insulated properly? With energy prices still stubbornly high and many UK households struggling to manage bills, loft insulation has become one of the most cost-effective upgrades you can make to your home.
If you’re looking to lower your heating bills, improve energy efficiency, and potentially qualify for government-funded insulation grants, this guide will walk you step-by-step through everything you need to know.
What Is Loft Insulation and How Does It Work?
Loft insulation acts as a thermal barrier, preventing warm air from rising and escaping through the roof. When installed correctly, insulation helps keep heat inside during winter and reduces overheating during summer.
There are multiple types of loft insulation:
Roll insulation (blanket insulation) – the most common option, easy to install.
Loose-fill insulation – ideal for irregular or hard-to-reach loft spaces.
Rigid insulation boards – great for lofts converted into a living space.
Saving potential: Loft insulation can reduce annual heating bills by £620–£750+ per year, depending on the size and condition of the property.
