Services
Cavity Wall Insulation
Cavity wall insulation reduces heat loss by filling gaps between walls with high-performance materials. Suitable for homes built between 19242005, this measure can save up to 300 annually on energy bills. Professional installers use mineral wool, polystyrene beads, or foam to meet building regulations and provide 25-year guarantees.
Loft Insulation
Loft insulation prevents heat escaping through roofs by installing mineral wool layers to recommended depths. Homes with less than 100mm existing insulation qualify for grants covering up to 100% of costs. Installation takes 12 hours, saving up to 355 yearly while improving EPC ratings.
External Wall Insulation
External wall insulation wraps properties in thermal boards, reducing heat loss by 33%. Ideal for pre-1920 solid-wall homes, grants cover up to 15,000 of costs. The process includes weatherproof finishes, adding property value while delivering annual savings of 180460.
Internal Wall Insulation
Internal wall insulation adds thermal boards or stud walls to solid walls, improving energy efficiency. Grants cover properties with EPC ratings D-G, saving 140700 annually. Installers provide tailored solutions for older homes where external work isn't feasible.
Room in Roof Insulation
Room in roof insulation fits boards between rafters in converted loft spaces, preventing 25% heat loss. Grants apply to habitable rooms with fixed staircases, costing 2,5006,000. Savings reach 150400 yearly while enhancing comfort in attic living areas.
