Frequently asked questions
How often does my business need a gas safety inspection?
A commercial Gas Safety Certificate is usually required every 12 months. This is a legal obligation for any business premises to ensure that all appliances, pipework, and safety devices are functioning correctly. Maintaining a current record is also a common requirement for your building insurance policy and general workplace safety compliance.
What is the difference between domestic and commercial gas services?
The transition from residential to commercial gas work occurs when the meter capacity exceeds a certain limit or when the appliances themselves are rated above 70kW. Commercial systems often involve larger diameter pipework and complex interlock systems that require specific Gas Safe sub-categories and higher-level technical training to manage safely.
What should I do if I suspect a gas leak in my office?
If you smell gas or suspect a leak, you should immediately evacuate the area and turn off the gas at the primary meter if it is safe to do so. Our team provides emergency gas repairs to locate and fix leaks quickly. We use calibrated detection equipment to identify the source of the breach and restore safety to your premises.
Can you handle gas installations for new commercial builds?
Yes, we manage everything from the initial site load calculation and system design through to the final Gas Appliance Installation and commissioning. We work alongside builders and architects during the shell-and-core or fit-out phases to ensure gas lines are safely integrated with other building services like HVAC and electrical systems.
How are the costs for commercial gas projects calculated?
The cost is determined by several factors including the size of the gas main, the number of appliances, the complexity of the fluming, and the specific access requirements of the building. We provide bespoke quotes after reviewing your plans or visiting the site to ensure the pricing reflects the actual demands of your commercial system.
