HTM 03-01 Parts A and B
HTM 03-01 is the central UK reference for specialised ventilation in healthcare premises. Part A covers design and validation of new systems; Part B covers operational management, maintenance and verification of existing systems. Both parts apply across the lifecycle of a healthcare ventilation system.
Supporting standards
BS EN ISO 14644 covers cleanroom particulate classification in pharmacy and ATMP environments. The HBN series covers room-by-room design requirements. CIBSE TM43 and BESA TR19 (Air) address ventilation hygiene. HSG 274 addresses the interface between ventilation hygiene and Legionella control.
What 'compliance' means in practice
Compliance means that systems serving clinical spaces deliver the air change rates, pressure regimes and filtration performance their classification requires — and that this is documented through assessment, validation, monitoring and hygiene records. Our services across this site map directly onto those documentation requirements.
