Do the regulations concern the size of the container or the amount of oil stored in it?
The Oil Storage Regulations 2001 (the regulations) apply to the size of the container rather than the contents. Sites with an oil tank capacity of 1000 litres, with 199 litres of stored oil, would fall within the regulations. Domestic properties with a storage tank greater than 3500 litres capacity, with only 2500 litres of stored oil, would fall within the regulations.
