FAQ

FAQs About Heating Oil Tanks

1. When should I replace my oil tank?

You should replace your oil tank if it shows signs of damage, corrosion, bulging, or leaks. Most tanks have a lifespan of around 20 years, but regular inspections can help determine when replacement is necessary.

2. How long does a heating oil tank last?

A well-maintained plastic bunded oil tank can last 15–20 years, while steel tanks may last slightly less due to corrosion risks. Regular servicing extends their lifespan.

3. Do I need a bunded oil tank?

Yes, in most cases. OFTEC and environmental regulations recommend bunded tanks (double-skinned) for domestic use to prevent oil leaks and environmental damage.

4. Where should I site my oil tank?

Oil tanks should be:

• 1.8m from non-fire-rated buildings and openings
• 760mm from wooden boundaries
• 600mm from foliage or screening
• Installed on a flat and levelled base.
  Compliance with Building Regulations and fire safety distances is essential.

5. Do I need planning permission to install an oil tank?

In most domestic cases, planning permission is not required, provided the tank is less than 3,500 litres and meets building and environmental regulations. Always check with your local authority.

6. What’s the difference between plastic and steel oil tanks?

Plastic tanks are lightweight, corrosion-resistant, and require minimal maintenance. Steel tanks are stronger, but may corrode over time without proper care.

7. How do I check my oil tank for problems?

Regularly inspect for:

• Cracks or bulging
• Rust (in steel tanks)
• Leaks around fittings
• Oil smells or staining on the ground
  An OFTEC or APHC technician can perform a full inspection.

8. Can I install an oil tank myself?

No. Oil tanks must be installed by a competent person, ideally a registered technician, to ensure compliance with BS 5410 and Building Regulations.

9. How big should my oil tank be?

The size depends on your oil usage, but 1,000 to 2,500 litres is typical for most homes. Larger tanks may be needed for commercial or agricultural use.

10. Is heating oil safe?

Yes, kerosene (heating oil) is safe and stable when stored correctly. However, leaks can be hazardous to the environment and property, so proper containment is essential.

11. Can oil tanks be placed underground?

Underground oil tanks exist but are not commonly used domestically due to cost and complexity. Above-ground bunded tanks are the most common for homes.

12. What’s the best base for an oil tank?

A base should be:

• Non-combustible
• Solid, fully supporting, flat, level concrete or paving slab base of at least 100mm thickness
• At least 300mm wider on all sides than the tank.
  Concrete or paving slabs are ideal.

13. How often should my oil tank be serviced?

Oil tanks should be inspected annually, ideally as part of your boiler service, by an OFTEC or APHC technician.

14. What are the legal requirements for domestic oil tanks in the UK?

You must comply with:

• Building Regulations
• Environmental Agency guidance
• OFTEC standards
  These govern tank location, capacity, bunding, and safety clearances.

15. What happens if my oil tank leaks?

You must act quickly:

• Stop or catch the leak if safe
• Contact an OFTEC or APHC technician
• Inform your insurer
• Report to the Environment Agency if there's risk to the environment
  Fines and cleanup costs can be significant, so regular maintenance is key.
