Why They Called Us

The Manchester homeowner was frustrated that the upstairs rooms never felt warm in winter and the heating bills kept climbing. They suspected the loft was losing heat, but wanted a survey-led recommendation rather than adding insulation blindly.

Customer Goal

Make the upstairs rooms feel warmer in winter and reduce heat loss from the loft.

What We Found on Survey

The 100m² loft had thin and uneven insulation, with compressed areas that no longer gave consistent thermal coverage. The survey also checked that eaves ventilation could remain open once the insulation depth was increased.

Why It Mattered

Insulation that is patchy or compressed leaves weak points above occupied rooms, making the house harder to heat. Increasing depth without protecting ventilation can also increase condensation risk, so the specification had to address both issues.

What We Did

EcoTrust Roofing & Insulation Ltd prepared the loft and laid mineral wool evenly to a measured 300mm depth across the 100m² area over two days. Eaves ventilation was retained, reflecting Building Regulations Part L guidance and BS 5250 moisture-control principles.

The Result

The finished loft had continuous 300mm mineral-wool coverage with the ventilation route kept clear. The homeowner received a clear specification and a 10-year workmanship guarantee for the installation.
