Commercial gas testing covering all aspects of commercial gas pipe work and appliances. 

Commercial gas testing is where CommGas Limited, Industrial and Commercial Gas Services, are proven commercial gas specialists. We have experienced industrial and commercial gas testing engineers and provide commercial gas testing for all aspects of industrial and commercial gas applications in London and throughout The U.K


This is where CommGas LimitedIndustrial and Commercial Gas Services, are proven commercial gas specialists. We have experienced commercial gas testing engineers and provide commercial gas testing in London, Greater London, Maidstone, Canterbury, Margate, Folkestone, Eastbourne, Brighton, Portsmouth, Southampton, Plymouth, Reading, Slough, Swindon, Bristol, Cardiff, Swansea, Coventry, Norwich, Birmingham, Leicester, Derby, Lincoln, Sheffield, Liverpool,  Manchester, Leeds, Hull, Blackpool, York, Middlesbrough, Carlisle, Newcastle, and throughout the whole of the UK.

Working to industry standards - IGE/UP/1A - Industrial and commercial gas pipework with a volume less than 1m3, also industry standards - IGE/UP/1 - Industrial and commercial gas pipework with a volume of 1m3 and above.

New industrial and commercial gas pipework will be designed to withstand a strength test pressure (STP) to identify any major flaw in the construction of the new gas installation pipework.

Tightness testing is carried out to ensure that the industrial and commercial gas pipework is safe for use, or continued use, so as not to cause a hazard or unsafe situation. Tightness testing for all gas pipework installations is carried out at a set pressure.

To ensure your commercial gas installation pipework is monitored and maintained in a safe condition, as set out in The Gas Safety (Installation & Use) Regulations 1998, we advise that all installation pipework be tested and inspected on an annual basis. This can normally be carried out at the same time as the annual gas appliance service visit.

When carrying out a direct or indirect purge, air to gas, or gas to air, our industrial and commercial gas engineers again work to the highest industry standards, with maximum level of planning & supervision.

They will implement all site precautions to be adhered to, thus, ensuring a safe working environment for all parties involved.

When any gas pipework de-commission works are carried out, the same level of expertise and workmanship are implemented, with all de-commissioned pipework left purged to air.

We can provide the complete package of works, from pipework sizing to appliance connection and commissioningor we can also provide any of the above as a 'stand alone' service should you require them.

We can also provide scheduled or reactive out of hours and weekend works, as and when required, to suit your needs.

Our industrial and commercial gas engineers are fully conversant with The Gas Safety (Installation & Use) Regulations 1998, enabling them to give the best advice on ensuring your installation is gas safe compliant with current regulations.

We provide all of the above industrial and commercial gas pipework related services in London, Greater London, Maidstone, Canterbury, Margate, Folkestone, Eastbourne, Brighton, Portsmouth, Southampton, Plymouth, Reading, Slough, Swindon, Bristol, Cardiff, Swansea, Coventry, Norwich, Birmingham, Leicester, Derby, Lincoln, Sheffield, Liverpool,  Manchester, Leeds, Hull, Blackpool, York, Middlesbrough, Carlisle, Newcastle, and throughout the whole of the UK
