ViperGas Commercial Collection 2026

ViperGas Commercial Collection – Domestic Natural Gas Handbook 2026 + Commercial Natural Gas Appendices

The ViperGas Commercial Collection combines two essential ViperGas technical publications for gas engineers extending their knowledge and qualifications from domestic natural gas into commercial natural gas.

This comprehensive collection contains the ViperGas Domestic Natural Gas Handbook – 2026 Edition together with the ViperGas Commercial Natural Gas Appendices, providing engineers with both the core gas engineering knowledge and the additional commercial-specific technical information required when progressing into commercial gas work.

Ideal for qualified gas engineers, trainees, apprentices, assessors and training centres, the collection provides an extensive technical reference for domestic and commercial natural gas, gas engineering training and ACS assessment preparation.

What's Included in the ViperGas Commercial Collection?

The ViperGas Commercial Collection contains the following two technical publications:

1. ViperGas Domestic Natural Gas Handbook – 2026 Edition

The ViperGas Domestic Natural Gas Handbook 2026 Edition is a comprehensive technical reference for domestic natural gas engineers, installers, trainees, assessors and training centres.

Updated for 2026, the handbook provides a three-book linear learning pathway covering essential domestic gas safety, installation, testing, servicing and appliance information.

The 2026 edition is IGEM/UP/1B Edition 4 compliant and includes a new chapter dedicated to CO, CO2 and Fumes Investigations.

Domestic Natural Gas Handbook – Key Topics

• Health & Safety
• Gas Regulations & Acts
• Combustion, Measurement & Testing
• Gas Controls
• Chimneys & Flues
• Ventilation
• Measurement of Gas Pressure & Tightness Testing
• Re-establishing Gas Supplies
• Pipe Sizing & Low-Pressure Gas Systems
• Checking & Setting Burner Pressure & Gas Rates
• Installation of Pipework & Fittings
• Low Pressure Meter Installations
• Statutory Requirements & Unsafe Situations
• Central Heating
• Space Heaters
• Gas Cookers
• Warm Air Heaters
• Water Heaters
• Tumble Dryers
• Fault Finding on Fan-Flued Combination Boilers
• CO, CO2 & Fumes Investigations

2. ViperGas Commercial Natural Gas Appendices

The ViperGas Commercial Natural Gas Appendices provides the additional technical information required by engineers working with commercial natural gas installations and appliances.

Designed to complement the Domestic Natural Gas Handbook, the Commercial Natural Gas Appendices builds upon core gas engineering knowledge with additional information specifically relevant to commercial gas work.

This makes the two publications particularly complementary: the Domestic Natural Gas Handbook provides the core technical foundation, while the Commercial Natural Gas Appendices provides the specialist information required when progressing into commercial gas engineering.

Commercial Natural Gas – Key Topics

• Commercial Gas Regulations & Requirements
• Combustion, Measurement & Testing
• Gas Controls & Safety Devices
• Room-Sealed Chimneys & Flues
• Commercial Ventilation
• Tightness Testing & Purging
• Installation of Commercial Gas Pipework & Fittings
• Statutory Requirements & Unsafe Situations
• Commissioning & Relighting Commercial Appliances
• Commercial Catering

From Domestic to Commercial Gas Engineering

The ViperGas Commercial Collection provides a logical technical pathway for engineers looking to progress from domestic natural gas into commercial gas work.

Rather than providing commercial information in isolation, the collection combines the comprehensive Domestic Natural Gas Handbook with the specialist Commercial Natural Gas Appendices.

This gives engineers access to their core gas engineering reference material alongside the additional information required when working with commercial natural gas installations and appliances.

Ideal for Commercial Gas Training

Engineers progressing into commercial gas work need to understand both the core principles of gas engineering and the additional requirements associated with larger and more complex commercial installations.

The ViperGas Commercial Collection has therefore been structured around two complementary technical resources:

• Domestic Natural Gas Handbook 2026 Edition – provides the core natural gas engineering reference.
• Commercial Natural Gas Appendices – provides supplementary commercial gas technical information.

Together, they provide a valuable technical reference for engineers undertaking commercial gas training and those preparing for relevant ACS commercial gas assessment or reassessment.

Commercial Gas Technical Reference

The collection provides technical information across the principal areas encountered in domestic and commercial gas work, including combustion and testing, ventilation, flues, gas controls, pipework, tightness testing and purging, unsafe situations and appliance commissioning.

Commercial-specific coverage also includes areas such as commercial catering, making the collection suitable for engineers looking to broaden their technical knowledge and scope of work.
