Protect Your EPC Rating with Loft Boarding, Installed By Instaloft in Partnership with EPC Choice

Boarding a loft directly onto ceiling joists might seem like a simple way to create storage, but it can have an unintended impact on how your home performs.

In many properties, joists are only 100–120mm deep, while insulation is typically designed to be laid at 270–300mm. When boards are installed directly on top, that insulation is compressed, reducing its depth and limiting its ability to retain heat effectively.

This becomes particularly important during an EPC assessment. Assessors can only record the insulation they can physically see at the time of inspection. If it has been compressed, it is assessed at that reduced level, regardless of what was originally installed.

The result is a loft that may not be performing as intended, and an EPC rating that doesn’t fully reflect the potential of your home.

When insulation is compressed, it can’t perform as it was designed to. Heat escapes more easily through the roof, reducing overall energy efficiency and potentially resulting in a lower EPC rating than expected.

For homeowners, this means missing out on the full benefit of their insulation. For landlords, it can create added pressure when working towards minimum EPC requirements.

This is where Instaloft can help.

Our raised loft boarding system is designed to work with your insulation, not against it.

By elevating the boarding above the insulation, the system preserves the full recommended depth while allowing airflow to circulate as it should. This helps insulation perform properly, while still creating a strong, stable and usable storage area.

No compression. No loss of performance. Just a smarter, EPC compliant solution to storage and insulation performance.
