Where Should a Bunded Oil Tank Be Located? UK Regulations, Safety & Best Practice

Correctly positioning a bunded oil tank is essential for safety, legal compliance, and long-term reliability. Whether you’re installing a new heating oil tank or replacing an existing one, the location you choose can affect everything from environmental protection to delivery access and maintenance costs.In this guide, we explain where a bunded oil tank should be located, covering current UK regulations, OFTEC guidance, and practical considerations for homeowners and businesses. We’ll also show how working with an experienced supplier like OTP Energy can help ensure your installation is safe, compliant, and hassle-free. 

UK Regulations and Guidance for Bunded Oil Tank Location

Before installing a bunded oil tank, it’s vital to understand the regulations and industry standards that govern oil storage in the UK.OFTEC GuidelinesOFTEC (the Oil Firing Technical Association) provides clear guidance for domestic oil storage systems up to 3,500 litres. Their recommendations are designed to reduce fire risk, prevent pollution, and ensure safe access for inspection and deliveries.You can find full official guidance in OFTEC’s home guide to domestic liquid fuel storage: https://www.oftec.org/consumers/off-grid-guides/home-guide-to-domestic-liquid-fuel-storage-up-to-3500-litres/Building RegulationsUK building regulations specify minimum separation distances between oil tanks, buildings, and boundaries. These distances help protect properties in the event of fire, leaks, or spills.Local authorities may also apply additional planning or environmental requirements, so it’s always advisable to check with your local council before installation. 

Minimum Distance Requirements for Bunded Oil Tanks

Meeting minimum distance requirements is critical for compliance and safety.Typical UK Distance Guidelines

• At least 1.8 metres from buildings, boundaries, and non-fire-rated structures
• At least 10 metres from watercourses such as rivers, streams, or drains
• Away from sources of ignition, including boilers, flues, and electrical equipment
• Clear of combustible materials such as wooden fencing, sheds, or decking

Correct spacing reduces the risk of fire spread and environmental contamination in the event of a leak.For practical examples of compliant tank positioning, this guide explains how and where to position your heating oil tank: https://www.northerntankstore.co.uk/how-and-where-to-position-your-heating-oil-tank 

Choosing the Right Base and Foundation

A bunded oil tank must be installed on a suitable base to ensure long-term stability and safety.Base Requirements

• The base must be level and structurally sound
• It must support the full weight of the tank when filled with oil
• Materials should be non-combustible, such as concrete or purpose-made oil tank bases

A poorly constructed base can lead to tank movement, stress on pipework, and increased risk of leaks over time. 

Ventilation, Access & Practical Considerations

Beyond regulations, practical access plays a major role in deciding where your bunded oil tank should be located.Key Practical Factors

• Ventilation: Ensure adequate airflow around the tank to prevent the build-up of fumes
• Delivery access: Oil delivery vehicles must be able to safely reach the tank fill point
• Maintenance access: Leave sufficient space for inspections, servicing, and repairs
• Security: Position tanks where they are protected from accidental damage or unauthorised access

Planning ahead helps avoid costly relocation or modification later. 

Common Locations for Bunded Oil Tanks

Bunded oil tanks can be installed in a variety of locations when guidelines are followed:

• Gardens or side passages of residential properties
• Purpose-built tank areas near rural homes or farms
• Commercial premises with dedicated fuel storage zones

The ideal location balances safety, accessibility, and compliance.
