Internal/External Wall Insulation
Wall insulation improves the thermal efficiency of your home by reducing heat loss through the walls — one of the main sources of energy waste. Whether your property needs internal wall insulation (for solid walls) or external wall insulation (for better exterior performance), we’ve got you covered.
Struggling with high heating costs or cold, damp walls?
At Eco Energy Upgrade, we provide professional Internal and External Wall Insulation services for homeowners across the UK — helping you stay warm, save energy, and access government-funded grants through ECO4 and GBIS.
