Insulation Type
Loft Insulation
Reduce heat loss through your roof by up to 25% with professionally installed loft insulation — fully funded through government grants.
What Is Loft Insulation?
Loft insulation involves laying mineral wool, fibreglass, or other insulating materials between and over the joists in your loft space. It creates a thermal barrier that prevents warm air from escaping through the roof — one of the biggest sources of heat loss in UK homes.
It is one of the simplest and most cost-effective energy efficiency measures available, and through government grants like ECO4 and GBIS, many households can have it installed completely free of charge.
