The annual gas inspection is an integral part of responsible building maintenance. It is simple to carry out, but crucial for safety. Chimney sweeps often perform this task on behalf of homeowners or as an additional service. This work requires a keen eye and reliable documentation. This is exactly where Esders’ TONIs come into play.
What is a gas system inspection and why is it so important?
According to the Technical Rules for Gas Installations (TRGI), a gas inspection is an annual visual inspection of all exposed gas pipes in a building. The aim is to detect damage at an early stage and prevent hazards, because even minor defects, such as inaccessible shut-off devices or incipient corrosion, can have serious consequences in an emergency.
The inspection includes:
✅ Freely laid pipes: Visual inspection for corrosion, damage or changes
✅ Shut-off devices: Are the main shut-off devices, i.e. the shut-off device behind the house connection and the meter shut-off, freely accessible?
✅ Concealed pipes: Is ventilation provided?
✅ Gas appliances & air supply: Are the appliances working? Is there sufficient combustion air supply?
Whoever carries out the gas inspection, whether the owner, a specialist company or a chimney sweep, must document it. It is precisely this documentation that becomes decisive evidence in the event of damage.
TONI GasTest CH4: Detect even the smallest leaks
Even though the gas inspection is not an active leak detection, many chimney sweeps and utility companies offer their customers an optional leak check. The TONI GasTest CH4 provides additional safety, especially on gas meters, fittings or in areas that are difficult to inspect, thanks to its flexible gooseneck.
With its high sensitivity to methane, easy use and clear digital display, the TONI GasTest CH4 is perfect for quick and selective checks. The measured values can be stored and documented directly.

How gas system inspection and serviceability testing complement each other effectively
What is the difference between a gas system inspection and a serviceability test?
Even though gas inspections and serviceability tests are often mentioned in the same context, they fulfil different purposes and are carried out by different trades.
Gas inspections are part of a chimney sweep’s daily work and are usually carried out annually. During these inspections, the gas installation is visually checked for any abnormalities: pipe layout, accessibility, odour, corrosion and the condition of fittings.
The serviceability test, on the other hand, is a technical measurement and is carried out by fitters or HVAC specialists. It is mandatory every twelve years and determines whether and how much gas is escaping from the pipe. This supplements the purely visual gas inspection with a precise metrological evaluation.
Both tests together ensure maximum safety: the chimney sweep detects any abnormalities, while the HVAC specialist measures, evaluates and repairs.
Can regular inspections of gas systems replace serviceability tests?
Operators remain obliged to carry out serviceability tests every 12 years, which cannot be replaced by regular gas system inspections. Only a combination of both types of inspections can guarantee that the gas system has no visible defects and is technically leak-proof and serviceable.
