Fire Door Regulations Have Changed

Since 2023, landlords and building owners across North Wales have increased responsibility for fire door compliance. Communal fire doors must be inspected every 3 months. Front entrance doors every 12 months. Non-compliance carries significant legal and safety risks.

Fire Door Compliance in North Wales

North Wales fire-door work is led by the public sector: NHS trusts (Betsi Cadwaladr University Health Board), school estates, social-housing landlords (Wales & West Housing, Cartrefi Conwy, North Wales Housing) and significant commercial estates around Wrexham and Deeside. The Welsh regulatory environment is broadly aligned with the English Building Safety Act for commercial premises, and the certifications and documentation we provide are recognised across the border.
