Membership & Accreditations
Constructionline Silver Membership
Constructionline Silver Membership Accreditation, Pro-Duct Clean are a verfied to the PAS 91 standard.
PAS 91 is a standardised pre-qualification questionnaire which has been developed to reduce the need for suppliers to complete a variety of different pre-qualification questionnaires for different, and in some cases, the same clients.
Developed by the British Standards Institute (BSI), the question set has been commissioned by Government and is a recommended common minimum standard for construction procurement.
Updates to PAS 91 have been introduced in 2013 through consultation with professional bodies and trade associations such as the National Federation of Builders (NFB), Electrical Contractors’ Association (ECA), Specialist Engineering Contractors’ Group (SEC) and Safety Schemes in Procurement (SSIP).
With all public sector buyers needing to pre-qualify construction suppliers; inefficient buying practices can amount to huge amounts of wasted time and money for buyers and suppliers alike.
By delivering a standardised PQQ format, PAS 91 aims to:
- Help suppliers understand what information is required from them at pre-qualification stage
- Increase consistency between various pre-qualification questionnaires and databases
- Help buyers identify suitably qualified contractors
Pro-Duct Clean Ltd demonstrate compliance with the CHAS standards in line with the SSIP Core Criteria and UK H&S Legislation and has been awarded accreditation tot he requirements of the CDM Regulations 2015.
Internal Cleanliness of Ventilation Systems – TR 19®
The internal cleanliness of ventilation systems is considered important for human comfort and health, energy consumption, system service life and for cleanliness of operations or processes carried out in the ventilated area
The guiding principle of TR/19® is that a defined, measurable level of cleanliness should be achieved. in cases of doubt regarding procedures, facilities and methods to achieve cleanliness then this principle defines success or failure.
General ventilation systems (not affected by kitchen grease) as defined, and referred to include, but are not limited to, the following:
• Air handling units
• Fan coil and induction units
• constant air volume units
• variable air volume units
• control dampers
• Air terminals
• Ancillary components associated with the air distribution system.
Kitchen extract systems as defined and referred to in this guide include, but are not limited, to the following:
• canopy/extract plenum
• discharge duct
• Ancillary components associated with the extract system other extraction systems that
may be affected by grease/oil deposits, eg dish wash, pot wash, general kitchen extract
• Fire dampers (where fitted) and attenuators.
Inadequate access to kitchen extract ducting has been shown to be a contributory factor to fires that spread through ducting. The designer therefore has a responsibility to ensure that adequate access is possible both through the building fabric to and into the system; thus ensuring that planned preventative maintenance (“PPM”) for full grease removal is practicable. The designer is advised to seek guidance from a specialist cleaning contractor at the design stage. TR19® Grease, a new, stand-alone specification for Fire Risk Management of Grease Accumulation within Kitchen Extraction Systems, can be read separately for the convenience of readers soley interested in this aspect of the cleanliness of Ventilation systems.
Table 1 (typical application of cleanliness quality classes) is applicable to all ventilation systems except kitchen extract systems and defines the levels of dust deposit at which it is appropriate to clean a general system. The levels of deposit referred to in Table 7 relate to normal nuisance dust and are based on good practice as well as the British and
European standard BS En 15780. Table 12 defines the level of grease deposit at which it is appropriate to clean a kitchen extract system and is again based on fire safety good practice.

DW 144 Standard
DW/172 B&ES Specification for Kitchen Ventilation
DW/172 is a definitive guide to kitchen ventilation systems in non-domestic properties. This publication has evolved to incorporate legislative change and new standards, and represents the most up-to-date and indispensable industry specification for HVAC specialists serving the catering sector.
DW/172 includes a new standard for grease filter testing from the Loss Prevention Council (LPS1263), endorsed by the Association of British Insurers (ABI). This section sets the standards demanded by British insurers to reduce the risk of fire in commercial kitchens and features detail on the certification of grease filters. In addition, the already comprehensive section on appliances and their coefficients has been further expanded, and advice has been included on the requirements for an interlock between the ventilation system and gas supply.
DW/172 clearly details all the requirements for the design, installation and maintenance of kitchen ventilation systems. DW/172 is a progression of the popular DW/171 that became the industry benchmark for kitchen ventilation systems after it was published in 1999, and is now a key part of HVCA Publications suite of literature intended to set standards for ductwork service and maintenance.
