Gas safety certification is not just a legal formality — it is the documented evidence that a Gas Safe registered engineer with the appropriate commercial qualifications has inspected your gas-fired appliances, verified they are safe to operate, and certified them as compliant with current gas safety regulations. For industrial and commercial operators across Merseyside, that documentation is essential for insurance, regulatory compliance, CQC assessments, HSE inspections, and the ongoing protection of staff and operations.

SMR Gas Maintenance engineers carry out gas safety inspections and issue certificates across the full range of industrial and commercial premises in Merseyside and the Liverpool City Region — from factories and warehouses at Knowsley Industrial Park, Speke, and Bromborough operating large-scale industrial heating and process equipment, to care homes across Liverpool and the Wirral with stringent CQC compliance requirements, commercial kitchens across Liverpool city centre requiring annual CP42 certification, and all general commercial premises across the area.
