Northern Gas Networks (NGN) engineers are working to repair a medium pressure gas pipe in Lower Cumberworth, Huddersfield.
Residents contacted NGN, using the National Gas Emergency Service phone line, reporting a smell of gas in the area and engineers have found a small leak on Shelley Woodhouse Lane.
They are working to repair the leak and no properties have been affected and the gas supply remains in place.
Anyone that smells gas or suspects carbon monoxide should call the National Gas Emergency Service immediately on 0800 111 999. This line is in operation 24-hours a day, seven days a week.
