Permitted Development Rules for an Oil Tank Installation
Generally permitted under Part 1, Class E of the GPDO (as an outbuilding). Oil tanks up to 3,500 litres are PD provided they are not between the dwelling and a highway, comply with outbuilding height limits, and do not cover more than half the curtilage.
Conditions
- 1Maximum capacity: 3,500 litres
- 2Must not be between the dwelling and a highway
- 3Must comply with outbuilding PD height limits
- 4Must not cover more than half the curtilage (combined total)
- 5Must be sited in accordance with OFTEC guidelines for fire safety and environmental protection
Size and Dimension Limits
- Capacity: 3,500 litres maximum
- Height: same as outbuildings (2.5m within 2m of boundary; 4m/3m elsewhere)
When Permitted Development Does Not Apply
- Tanks over 3,500 litres are not PD
- Must not be forward of the principal elevation
- Environmental regulations apply to prevent oil spills (Oil Storage Regulations 2001)
- Secondary containment (bunding) is required for tanks over 200 litres in certain areas
What About Building Regulations?
Building regulations approval is likely required
Building Regulations apply under Part J (combustion appliances and fuel storage). Covers tank construction, bunding and secondary containment, fire separation distances from buildings, ventilation, and oil supply pipework. An OFTEC-registered installer can self-certify the work.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Gravesham building control or use an approved inspector.
How to Apply in Gravesham
If you need planning permission for your oil tank installation, you can apply through Gravesham's planning department or via the national Planning Portal.
If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Gravesham. This provides proof that your project does not need planning permission, which can be helpful when selling your property.
What Happens If I Build Without Permission?
Low planning enforcement risk for tanks within PD limits. Environmental enforcement is a greater concern: oil spills from poorly installed or maintained tanks can result in prosecution by the Environment Agency and clean-up costs of tens of thousands of pounds.
