New figures released by Northern Gas Networks have highlighted just how important gas safety remains across Leeds. Between January and March 2025, engineers were called to 94 properties in Leeds following reports of confirmed or suspected carbon monoxide incidents. Across Yorkshire, a total of 289 emergency callouts were attended during the same period.
Although these figures may come as a surprise, they demonstrate that gas safety should never be taken for granted.
Carbon monoxide cannot be seen, smelt or tasted. Nevertheless, it can be deadly if it is allowed to build up inside a property. Because the symptoms often resemble those of flu, including headaches, dizziness, nausea and tiredness, the warning signs may easily be overlooked.
Furthermore, many incidents can be prevented through regular maintenance and by ensuring that gas appliances are installed and serviced correctly.
Northern Gas Detects High Levels for Leeds Family
One Leeds family discovered just how serious the risk can be. After their carbon monoxide alarm sounded, it was initially believed that the batteries might simply need replacing. However, when engineers from Northern Gas Networks attended the property, dangerous levels of carbon monoxide were detected. Consequently, the gas supply was isolated until the faulty boiler could be repaired by a Gas Safe registered engineer.
Fortunately, stories such as this also demonstrate why carbon monoxide alarms are so important. Without one, the outcome could have been very different.
In addition, homeowners should never assume that a boiler is safe simply because it appears to be working normally. Faults can develop over time, while worn components may go unnoticed until they become dangerous. As a result, annual servicing should always be considered an essential part of home maintenance rather than an unnecessary expense.
Similarly, anyone arranging gas work should always check that the engineer is listed on the Gas Safe Register. Their identification card should be requested before work begins, and the qualifications shown should match the appliance being installed or repaired. By taking these simple precautions, legal requirements can be met and unnecessary risks can be significantly reduced.
Using a Gas Safe Engineer in Leeds
Ultimately, the latest figures from Northern Gas Networks serve as a timely reminder that carbon monoxide incidents continue to occur across Leeds. Although most households will thankfully never experience an emergency, gas safety should never be left to chance. Instead, regular servicing, working carbon monoxide alarms and the use of a Gas Safe registered engineer should always be treated as essential steps in protecting your home and everyone living within it.
It is important to understand that Northern Gas Networks responds to gas emergencies and manages the gas distribution network. However, any repairs to boilers or other gas appliances must be carried out by a Gas Safe registered engineer before the appliance can be safely returned to service.
