Gas Leak Detection

About our gas leak detection service

Gas leaks can manifest as a subtle scent of rotten eggs or a more technical drop in pressure noted during a routine service. In both residential homes and commercial facilities, identifying the precise location of a fault is critical for safety and operational continuity. Our gas leak detection service utilises a combination of electronic sensing technology and traditional pressure testing to find vulnerabilities in your pipework. This process is essential for landlords managing HMOs, business owners overseeing industrial kitchens, and homeowners concerned about their internal gas lines. By identifying the source of a leak quickly, we can move directly into Emergency Gas Repairs or recommend a partial Gas Pipe Installation to rectify the fault. Our engineers are trained to handle complex layouts, from domestic copper piping to large-scale commercial steel installations, ensuring every joint and valve is verified for integrity. Whether you are dealing with a suspected emergency or require a precautionary check, our methodical approach ensures your gas system meets all current UK safety standards.

What's included

• Tightness Testing

  Formal testing used to confirm the seals on your entire gas system are holding pressure correctly and are free from even minor seepages.

• Electronic Trace and Access

  Non-invasive detection using calibrated electronic sniffers that can find gas leaks behind cupboards, under floorboards, or in ceiling voids.

• Appliance Connection Audits outdoor

  A thorough check of all gas-fed appliances, such as hobs, ovens, and fires, to ensure the leak is not originating from an appliance fault.

• Pipework Integrity Mapping

  For complex commercial sites, we map out the gas pipework to identify high-risk areas or ageing sections that may require replacement.

• Safety Documentation

  Providing a detailed written report of our findings, which can be used for insurance claims or as part of your health and safety records.

Key benefits

• Immediate Risk Mitigation

  Rapidly pinpointing gas leaks prevents small issues from becoming major safety hazards or expensive repair jobs later on.

• Minimal Property Disruption

  Our precise detection methods ensure that only the affected section of pipework is accessed, reducing unnecessary damage to your property.

• Regulatory Compliance

  Regular tightness testing and leak checks keep your premises compliant with the latest UK Gas Safety Regulations and insurance requirements.

• Advanced Accuracy

  Modern electronic sniffing technology identifies trace amounts of gas that are often undetectable by smell alone, providing total peace of mind.

• System Efficiency

  A confirmed gas-tight system works more efficiently, helping to maintain consistent pressure for boilers, cookers, and industrial machinery.

Our process

1. 1
   Initial Site Survey

   We begin with a visual inspection of all visible pipework and gas appliances to check for obvious signs of corrosion or damage.

2. 2
   Pressure Tightness Testing

   Using a digital manometer, we measure the gas pressure within the system to confirm if a drop is occurring, indicating a leak.

3. 3
   Electronic Sniffing

   Handheld electronic sensors are moved along the pipe runs to detect trace levels of gas molecules in the air, pinpointing the leak source.

4. 4
   Diagnosis and Reporting

   Once the leak is located, we discuss the best course of action, whether it involves a simple joint tightening or more extensive repairs.

5. 5
   Verification Testing

   After repairs are completed, a final tightness test is performed to ensure the entire system is completely sealed and safe for use.
