Why Regular Gas Servicing is Essential for Your Business

In the United Kingdom, commercial gas servicing is a strict legal requirement. Under the Gas Safety (Installation and Use) Regulations 1998, employers and landlords must maintain gas appliances and pipework in a safe condition.

Prevent Costly Breakdowns

We catch minor faults during routine gas servicing before they turn into expensive emergency repairs.

Ensure Legal Compliance

Protect your business from liability. Secure your annual Commercial Gas Safety Certificate (CP17) effortlessly.

Lower Energy Bills

Clean, serviced gas boilers burn fuel much more efficiently, directly reducing your operational costs.

Workplace Safety

Regular gas servicing eliminates the risk of carbon monoxide (CO) leaks, keeping your staff safe.

Our Rigorous Gas Servicing & Inspection Process

We do not believe in quick visual checks. Our certified engineers perform a deep, technical multi-point inspection to ensure every part of your system is operating at peak performance.

Visual Inspection

Visual Inspection

Our process begins with a detailed visual examination of the appliance casing, surrounding pipework, and the overall installation setup. This step is crucial because it allows our engineers to identify early signs of corrosion, physical wear-and-tear, or ventilation defects before they turn into major system failures.

Flue & Ventilation Test

Flue & Ventilation Test

We thoroughly test the flue terminal, air supply systems, and ventilation pathways. Proper ventilation is vital for any commercial system, as this check guarantees that all dangerous combustion gases are being safely extracted outside the building, keeping your indoor air clean and risk-free.

Operating Pressure

Operating Pressure

Our engineers precisely measure both the gas pressure and burner pressure settings against manufacturer specifications. Correct operating pressure ensures that your heating systems are burning gas at the optimal, safe rate, which stabilizes your energy consumption and prevents over-firing.

Safety Devices

Safety Devices

We run specialized tests on all built-in safety controls, including flame failure devices, pressure cut-offs, and internal mechanical seals. These components are your system's primary defense line, and verifying their responsiveness ensures the system will automatically shut down safely in case of an unexpected malfunction.

Flue Gas Analysis

Flue Gas Analysis

Using calibrated electronic gas analysers, we measure the precise ratio of carbon monoxide (CO) and carbon dioxide (CO2) being produced. This digital analysis gives us absolute proof that clean, efficient combustion is taking place, eliminating the danger of toxic, unburned emissions leaking into your workplace.

Frequently Asked Questions

Find answers to the most common questions about our commercial gas servicing.

How often should a commercial gas servicing be carried out?
By UK law, commercial gas appliances, boilers, and pipework must be inspected and serviced at least once every 12 months by a Gas Safe registered engineer.
+
What is the difference between a gas safety check and gas servicing?
A gas safety check is a legal inspection to ensure appliances meet safety regulations. A gas servicing, however, is a deeper maintenance process where the engineer cleans, tunes, and optimizes the internal components to prevent breakdowns.
