Gas appliances and heating systems must be installed, maintained and repaired with safety as the priority. Whether you need help with a boiler fault, a routine service or another gas heating requirement, it is important to use an engineer who is appropriately qualified and registered for the specific work involved.
At London HVAC, we understand how important it is for customers to have confidence in the people working on their heating systems. We help customers discuss their gas-related requirements and the appropriate next steps. All work legally requiring Gas Safe registration must be carried out by an engineer whose registration and qualifications cover the specific appliance and task. We do not treat gas safety as an optional extra.

Gas-related work covers several different tasks. The exact requirements depend on your appliance, property and the nature of the job.
A boiler that is not working properly may have an electrical, mechanical or gas-related fault. A suitable assessment is needed to establish the cause. Gas components and other regulated work must only be handled by an appropriately registered engineer.
Routine servicing helps assess the condition and operation of a gas boiler. The engineer follows the appropriate checks for the appliance and manufacturer, looking for issues that could affect safe and reliable operation.
Gas appliances need to be installed and maintained in accordance with applicable safety requirements. If you have concerns about an appliance, unusual operation or a possible gas leak, it is important to follow the appropriate emergency safety advice rather than attempting to investigate the appliance yourself.
Heating problems can involve the boiler, controls, circulation or connected equipment. Understanding the wider system helps establish whether the issue relates to the gas appliance or another part of the installation.
