Gas Purging And Tightness Testing

As a company, we are able to provide tightness testing on new and existing gas purging pipework within the commercial and industrial sectors.

A gas tightness test is carried out to ensure that the commercial or industrial gas pipework is safe for use, or continued use, as so not to cause a hazard or unsafe situation. Tightness testing for all gas pipework installations is carried out at operating pressure. If any new gas pipework installation or new extension has been carried out to existing gas pipework then this will require purge and tightness testing.

This is to verify that within any tolerances caused by the limited time for testing and the accuracy of fully calibrated instruments used, the pipework is nominally gas tight and is safe for use. If the smell of gas or the presence of gas is detected, even after a satisfactory tightness test, then this would fail the test and would require to be traced and repaired.

These tests exist to ensure that your commercial gas installation pipework is maintained in a safe condition, as set out in The Gas Safety (Installation & Use) Regulations 1998. We would also recommend that all gas installation pipework be inspected and tested on an annual basis, which would normally be carried out at the same time as an annual service on any gas appliances or equipment. Tightness testing should only ever be carried out by an approved commercial gas safe engineer. All completed works will be issued with the correct gas safe certificates and documentation.

Strength Testing

Strength testing is only carried out when any new commercial, or industrial gas pipework installations or extensions to existing commercial gas pipework installations have been made.


Our highly skilled commercial and industrial gas engineers here at Boiler and Burner Services Ltd will carry out works of any scope, bearing in mind that we work to the highest level of industry standards. Boiler and Burner Services Ltd will carry out a thorough survey of the gas installation pipework. Only when our engineers are fully satisfied that they have all the correct information required and that all necessary risks have been evaluated, will they then proceed to carry out the works in a safe manner.

Purge and Decommission

When Boiler and Burner Services Ltd engineers carry out a direct or indirect purge, air to gas, or gas to air, our commercial gas engineers again will work to the highest industry standards, with a paramount level of planning & supervision. With any gas pipework decommission works will be carried out with the same level of prowess, competence and professionalism.

As a company, we can provide the complete package of works: from pipework installation, correct pipework sizing to any appliance connection and commissioning. Alternatively we can provide any of the above as a ‘stand alone’ service, should this be required.

Our commercial gas engineers are experienced and fully knowledgeable in regards to the Gas Safety (Installation & Use) Regulations 1998. This enables us to give the best advice on ensuring your gas installation is gas safe compliant and meets all current regulations.
