Clean, well-maintained pipework systems are essential for ensuring building safety, system efficiency, and compliance with health and safety legislation.BSRIA BG29(Pre-Commission Cleaning of Pipework Systems) provides the recognised framework for cleaning and commissioning closed heating and cooling systems before operation.
At Marlowe Environmental Services, we help facilities managers, contractors, and building owners implement BG29 requirements effectively. Our water hygiene experts ensure that systems are correctly flushed, treated, and verified in accordance with national standards and legal obligations.
BSRIA BG29 is published by the Building Services Research and Information Association (BSRIA) and provides best-practice guidance for cleaning, flushing, and chemical treatment of closed water systems. Its purpose is to remove debris, corrosion, and microbiological contamination before systems are brought into service.
The guidance supports compliance with key workplace safety regulations, including the Health & Safety at Work Act 1974, COSHH Regulations, and the Workplace (Health, Safety and Welfare) Regulations 1992.
