A strong oil smell may be caused by a spill, leak, boiler fault or problem with your heating oil tank. You should not ignore it. Acting quickly can help reduce the risk of damage and keep your home safe.
If the smell is strong, ongoing or getting worse, contact a qualified engineer or fuel professional for advice.
First Steps
If you smell oil, take these steps:
- Turn off your heating system if it is safe to do so
- Keep children and pets away from the area
- Avoid touching spilled oil
- Do not use naked flames nearby
- Do not smoke near the smell or spill
- Ventilate the area if the smell is indoors
- Check whether the smell is near the tank, boiler or pipework
If you feel unwell, leave the area and seek medical advice.
Check the Oil Tank
If it is safe, look around your heating oil tank for obvious signs of a leak.
Check for:
- Oil stains on the ground
- Wet patches near the tank
- Strong smells around the tank
- Cracks or splits
- Bulging or distortion
- Damaged pipework
- Loose fittings
- Oil around the tank base
Do not climb on the tank or try to repair it yourself.
Check the Boiler Area
If the smell is indoors, it may be linked to the boiler or fuel line.
Look for:
- Smells near the boiler
- Oil marks around pipework
- Drips or damp patches
- Boiler fault lights
- Recent service or repair work
Contact a qualified heating engineer if you suspect a boiler issue.
What Should You Avoid?
Do not:
- Ignore the smell
- Use the heating if you suspect a leak
- Wash oil into drains
- Try to patch the tank yourself
- Order more oil before the tank has been checked
