If you use heating oil and spot oil stains or pooling, it could be a sign that your boiler is leaking. The smell of oil might also be stronger than normal.
Close the tap or valve on the oil tank, and open the windows to prevent fumes from building up. If it’s safe to do so, try to collect any leaking oil in a tub, or contain it by putting down sand or earth. Don’t wash it away!
Get help by calling out a heating engineer or your home insurer’s emergency number. And if anyone feels sick or dizzy, leave the house immediately.
