External Oil Tank Removal
If you're upgrading your oil tank or even changing your heating system, you'll need to remove your oil tank safely and within regulations.
There could be a number of reasons why you may need to have your oil tank removed. For example, it’s too old and needs upgrading, it is damaged, you’re renovating a property, you’re changing your heating requirements or you just need a bigger tank for a growing family. But a word or caution – removing an oil tank and disposing of it yourself is not an option so, please do not do it yourself and always hire professionals.
Your heating oil tank should be inspected and serviced by an OFTEC registered heating engineer every year, as well as your heating system, as they will advise you if there are any problems and if your oil tank needs to be replaced.

Q: How do I know if my oil tank needs replacing or removing?

A: Yes. Any remaining fuel will typically need to be safely drained or transferred before the tank can be disconnected and removed.
