New BSRIA guide reinforces ‘no insulation without ventilation’

The guide highlights the need to balance energy efficiency improvements with effective moisture management

The principle of ‘no insulation without ventilation’ underpins a new guide to eliminating damp and mould in social housing.

BG 90/2026 Dealing with mould in social housing has been launched by the Building Services Research and Intelligence Association (BSRIA) to help landlords and construction professionals navigate requirements introduced by Awaab’s Law. It highlights the need to balance energy efficiency improvements with effective moisture management.

BG 90/2026 has cutting-edge approaches – such as tracking humidity using sensors and stock-level risk assessment using housing data – to support a shift from reactive maintenance to proactive, data-driven management.

Tom Garrigan, executive director of BSRIA, said: ‘Continuous, demand-controlled ventilation systems are essential for reliable moisture control, especially as homes become more airtight through retrofit measures.’
