Do I Need Planning Permission for a Oil Tank Installation?
Installing a domestic oil storage tank for heating oil. Oil tanks are treated as outbuildings under permitted development and have specific conditions regarding capacity and position.
The General Position
This project is usually allowed under permitted development rights without needing to apply for planning permission, provided certain conditions and limits are met.
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 and Requirements
- 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 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. You may need both, one, or neither depending on your project. Building regulations cover the safety and quality of building work, including structural integrity, fire safety, insulation, ventilation, and drainage.
How to Apply for Planning Permission
Check if you need permission
Review the permitted development rules above. If in doubt, contact your council or apply for a Lawful Development Certificate.
Prepare your application
You will need scaled drawings, a site plan, and a completed application form. An architect or planning consultant can help with this.
Submit to your local council
Applications can be submitted online via the Planning Portal or directly to your council. Select your council below for a direct link.
Wait for a decision
8 weeks for householder planning applications if PP is needed..
Application cost: £258.
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.
