A guide to heating oil tank replacement

Whilst most heating oil tanks will last around twenty years, as they age the likelihood of problems increases. It’s important to check your tank regularly, especially in advance of any heating oil deliveries. If your tank is over 10 years old, it’s even more important to check for any signs of damage, or for risks of leaks and spillages. If your heating oil tank is old, damaged and needs replacing, our expert tank team are here to guide you through your options. We have a dedicated team of experts and a wide range of tanks to choose from.

When to replace your heating oil tank

A leak or a spill from a damaged oil tank can cost up to £30,000 to clear up. That’s why it is important that you arrange a full annual inspection of your oil storage tank by a professional; preferably an OFTEC Registered Technician. They will be able to tell you if your tank needs replacing. If you order your heating oil from Certas Energy, we will also give your tank a visual inspection every time we come to deliver your fuel. You also need to do regular checks yourself to protect you, the environment and anyone that is coming to your home to fill up your tank with heating oil.

Tank Checklist:

  • Check for signs of damage, such as bulges, cracks, rust, discolouration or major dents. These are signals your tank is weakened.
  • Regularly check for spills and leaks and check your pipework.
  • Make sure you have an oil spill kit, just in case, with drain blockers, leak-sealing putty and absorbent materials
  • Make sure fuel gauges and fill points are in a good working condition. If they aren’t, your tank could be dangerously overfilled
  • Make sure vents and gauges are closed so that insects or dirt don’t get into them
  • Keep an eye out for unusual increases in your fuel usage, they could potentially signal that your tank is no longer working correctly
  • Keep your tank on a solid level surface.

Heating Oil Tank installation and building regulations

If you are installing a new tank it is important it complies with local Building Regulations. In England and Wales OFTEC registered technicians can self-certify their own work without involving Local Authority Building Control. If you choose someone who isn’t registered with a competent scheme like this, then you will have to obtain a Building Control Notice. 

Building regulations advise that all new oil tanks installed are bunded. A bunded oil tank is one that has a secondary containment to help protect against leaks and spillages. Essentially a tank within a tank. The oil is contained in the inner tank and the outer tank acts as protection. Should a leak or spillage occur, the fuel would be contained in the bund area. They also provide added protection from the weather and elements.

Here’s some guidance on when you need a bunded tank:

Under oil tank building regulations for England and Wales, if the oil storage tank’s capacity is over 2500 litres it must have a secondary containment (bunding). 

If it is up to 2500 litres it may also need a secondary containment depending on the outcome of an individual site pollution risk assessment. 

However, oil tanks with less than 2500 litre capacity must be bunded if the tank is:

  • Within 10 metres of controlled water
  • Located where a spill could run into an open drain or to a loose manhole cover
  • Within 50 metres of a borehole or spring
  • Over hard ground or hard surfaced ground that could enable spillage to reach controlled water
  • Supplying heating oil to a building other than a single family dwelling

The good news is, we supply fully bunded tanks as standard, and all our tank installers are OFTEC registered.
