Frequently asked questions about Gas Testing & Purging

When is a tightness test required?
A tightness test is required on all new gas installations, after any modification to gas pipework, after disconnection and reconnection of pipework, and as part of a CP12 landlord gas safety check.
What is the difference between a let-by test and a tightness test?
A let-by test checks that the meter and ECV are not passing gas when in the off position. A tightness test checks the integrity of the pipework downstream of the meter by pressurising the system and monitoring for pressure drop.
What pressure drop is acceptable?
Tightness testing must be carried out in accordance with IGEM/UP/1B. The installation must show no perceptible movement on the gauge over the test period. Any movement indicates a leak that must be found and repaired.
