Thorough pre-commission cleaning of pipework systems continues to be important with the adoption of energy efficient controls strategies that may result in low flow rates.

This guide provides the latest thinking and good practice cleaning techniques. It aims to clarify the roles and responsibilities of the parties, improve the exchange of information between them and provide consistency between service offerings of the pre-commission cleaning contractors.

Pre-commission cleaning is achieved through a process of flushing and chemical cleaning (where required) followed by the addition of biocides and inhibitors. Systems designed and cleaned in accordance with BSRIA's guidance are far less likely to experience operating problems.

Contents include:
- Design considerations
- Inspection and witnessing
- Installation considerations
- System dynamic flushing
- Chemical cleaning procedure
- Connections between new and existing systems

Editable Excel versions of the pro-formas in appendices C and D of this publication are attached to the pdf of this guide, and are available as a free download to anyone purchasing a hard copy of the guide.

Common customer questions & answers

QQuestion Which edition of BSRIA’s Pre-commission Cleaning guide should I be using?
AAnswer The current edition of BSRIA’s Pre-commission Cleaning guide is BG 29/2021. It was revised in partnership with the CSCA with input from an industry steering group, members of which are listed in the guide. It supersedes all previous editions of the guide. It is BSRIA’s intention that, in normal circumstances, BG 29/2021 should be used in preference to any superseded editions of the guide. Superseded versions of the guide are still available (see Revision History above) as they provide useful reference information for older projects. Users of BG 29/2021 should be aware that it is a guide, not a regulation. It is for individual project teams to decide whether to follow the guidance, and this should be made clear in project documentation.
