If you suspect a gas leak, a plumber will first conduct a pressure test. This is a relatively simple process that should cost $75 to $150 and take around 30 minutes to complete. However, some parts of the country will require a lengthier gas line pressure test that will take more than 24 hours and cost up to $500.
Some code requirements call for a gas line pressure test to detect leaks via pressure drops. Standard tests cost between $75 and $150. However, some local codes call for 12-hour or 24-hour testing that can cost as much as $500.
Certified professionals, such as HVAC professionals, employ pressure on the gas line to ensure that the pipes, joints, fittings, and other important components are functioning properly.
The cost of leak detection is separate from that of performing repairs. Detecting a gas leak is also different than detecting a water leak. It's not unheard of to spend a few hundred dollars on this step alone. However, the exact cost depends on the method used and how the company sets its rates.
Calling a plumber might not be your first thought when you smell gas. Not every plumber can do the job. Don't expect an apprentice or general contractor to be ready to handle the task. Check the plumber's qualifications; they must have a California C-36 Plumbing Contractor license to work with gas lines.

Hold the pressure
Maintain the pressure for a specified period of time, usually at least 15 - 30 minutes but sometimes as long as eight hours or more.
Common leak-test methods are pressure and vacuum decay, tracer gas detectors, and a bubble soap leak detector. Trades and homeowners alike can use a bubble soap leak detector to check piping systems for leaks.
Natural Gas Nominal Operating Pressure:
3.5” WC (minimum) to 7” WC (maximum) 6” WC recommended for optimal operation.
The more appliances you have, the higher the cost. On average, the cost of a gas certificate for a property with 1 boiler, gas hob, and fireplace can range from £34 – £90. If you have a gas fire in multiple rooms, two boilers and a hob then you would pay more then someone who just needed their boiler and hob checked.

Use a Gas Leak Detector
These devices are specifically designed to detect the presence of natural gas or propane in a given area. They can be handheld or mounted in a fixed location. They will typically emit an audible alarm when a leak is detected.
Homeowners should plan on having an annual gas inspection. Be wary of assuming that all is well and carrying on without having your gas appliances checked each and every year.

This means checking anything connected to gas lines, including cooking, heating, outdoor appliances, and more.
