What is Loft Insulation?
Loft insulation is one of the best methods of minimizing heat loss. If your house is not well-insulated in the loft, as much as 25% of your heat might leak through the roof. Loft insulation insulates your attic or loft space as a heat barrier between the outside air and your living space.
Advantages of loft insulation:
- Keeps your house warmer in the winter and cooler in the summer
- Enhances your house’s EPC (Energy Performance Certificate) rating
- It may last for 40 years or more with little maintenance
- Instantaneously minimizes the demand for heating
what is cavity wall insulation?
The majority of houses constructed between the 1920s and 1990s had outer walls containing an air gap, or “cavity,” between two courses of brick. The cavities are easy to lose heat from unless they are filled. Cavity wall insulation fills the gap with insulation like foam, beads, or mineral wool to stop heat loss and make the building more comfortable.

Types of Home Insulation Grants Offered
The UK government, through initiatives such as ECO4 and the Great Britain Insulation Scheme, provides various home insulation grants to make homes warmer, more energy efficient, and less expensive to heat. Below are the principal types of free insulation grants offered today:
Free Loft Insulation Grant
Loft insulation keeps 25% of your home’s heat from being lost through the roof. If your loft is not insulated or under-insulated, you can get free loft insulation professionally fitted at no expense to yourself.
Internal Wall Insulation Grants
If your house has solid walls and no cavity to insulate, you could be in line for internal wall insulation grants. This means fitting insulation onto the inner face of exterior walls—the perfect solution for difficult-to-treat homes.
Free Cavity Wall Insulation Grant
Older houses with empty wall cavities lose more than a third of their heat. With grants for cavity wall insulation, this gap is filled with energy-efficient material to trap warmth and reduce heating costs.
Complete Loft and Cavity Wall Insulation
Certain homes might be suited to both free loft and cavity wall insulation. This dual measure optimizes energy efficiency and minimizes heat loss from roofs and walls alike.
Free Grant for Insulation Upgrades
Even if your house is already insulated, you might still be eligible for an upgrade if it’s old, damaged, or inefficient. Under the free home insulation scheme, you can have new, high-performance insulation materials installed free of charge.
With government grants for house insulation, you can keep warm, reduce your energy bills, and enhance your property’s EPC rating—all without paying a penny upfront.
