Steel Oil Tanks

Here at Tuffa we manufacture single skin and bunded steel oil tanks, which can hold from 900 litres – 100,000 litres of fuel. With over 30 years’ experience in the industry, we offer steel oil tanks at a standard we believe no other manufacturer can match.

Steel Oil Tanks Information

At Tuffa we manufacture bespoke steel oil storage tanks. Our steel oil tanks are available in single skin or with a bund (a tank within a tank which provides additional protection from leaks and spills).  


Single skin tanks benefit from their low price and can hold fuel capacities of 900 litres to 2,300 litres. Our steel bunded fuel tanks are integrally fitted with a secondary containment and are therefore more secure and environmentally friendly than single skin fuel tanks. These are available in sizes from 900 litres to 100,000 litres and can also be fitted with fire protection to provide extra protection to your premises and contents.  


While our steel oil tanks are available in a standard range, we can also manufacture steel tanks to bespoke requirements. That makes steel oil tanks the perfect solution for those looking to replace an existing fuel storage tank and need the new tank to fit exact dimensions. The high-quality mild steel used in the production of our tanks is extremely durable and weatherproof. Our steel tanks are designed with a life expectancy of at least 30 years.  


Tuffa’s bunded steel oil tanks are a completely self-contained, ready-to-use, sealed unit making them easy to move when empty and ensuring a low requirement for maintenance as no rainwater can enter the bunded area. Each tank comes with a high specification as standard with only premium ancillary equipment used. For any advice and to discuss steel oil tank requirements call our sales team on 01889 567700 or complete an online enquiry form.  


You can also check out An Expert Guide to Heating Oil Storage for information, advice and industry insights covering everything from the basic question “what is heating oil?” to the money-saving “how can I get the best price for heating oil?”   Additionally, we also manufacture plastic fuel tanks, which are durable, more lightweight and can hold up to 15,000 litres of fuel . You can find out more information on our plastic heating oil storage tank range here.  



Our steel oil tanks can be a long-term investment. The bigger the capacity tank you order, the more money you can save on kerosene storage, albeit at the greater initial cost of the tank. Bulk buying kerosene has numerous benefits. Kerosene prices often fluctuate so buying fuel when prices are low and making the most of any deals or incremental savings offered by your fuel supplier, can give you real savings on fuel.  


A higher capacity also means you need to refuel less frequently, reducing the price you pay for deliveries and diminishing the risk of running out of fuel altogether. As Tuffa steel oil tanks are designed with a life expectancy of at least 30 years, these savings can really start to add up and surpass the additional costs of purchasing a larger capacity tank. That’s why we recommend the highest possible capacity for your budget and available space.  


As a guide, we recommend the following capacities for domestic use:   steel oil tank litres information for different sized houses



Our bunded steel oil tanks come with a 10-year guarantee when registered and our single skin tanks come with a 2 year guarantee when registered. All of our tanks have a 1 year guarantee on ancillary goods. We recommend regular maintenance of your tank to extend its usable life.

To comply with Local Authority Building Control your oil tank installation needs to be signed off by a Competent Person. We recommend using members of the Association of Plumbing & Heating Contractors (APHC) who can install the tank to meet regulations and self-certify their work. Find APHC installers.  


Single Skin vs Bunded Steel Oil Tanks

Before choosing a single skin and bunded steel oil tank, it’s important to assess the advantages of each option. We recommend a bunded oil tank, especially if you’re considering storing large quantities of oil, as this provides a more versatile and safer solution.  


Single skin oil tanks provide a lightweight and low-cost alternative to oil storage and are ideal for storing smaller quantities of fuel. Legally, single skin tanks can hold up to 3,500 litres of oil (from 900 litres – 3,500 litres). Single skin tanks provide much more limited protection against spills and damage, meaning that it can be harder to find the best place to store your tank.   Bunded steel tanks provide a much more secure, cost-effective solution to heating oil storage.


Bunded steel oil tanks can hold from 900 litres to 100,000 litres of oil and have a secondary container that is 110% of the actual storage capacity. The secondary containment (bund), provides protection from damage and spills, meaning that oil can be contained safely without causing any environmental damage or costing you any more money.  



The Control of Pollution Regulations (Oil Storage) (England) Regulations 2001 dictates the legal requirements for storing oil on a property in England. The main points are:  


  •         All oil tanks with a capacity of 3500 litres or more must have a secondary containment (a bund).
  •         All oil tanks located in an area where spills risk polluting surface and groundwater must have a secondary containment (a bund).
  •         Oil tanks must be made of a material suitable for the oil type stored.
  •         Ancillary equipment (not including the fill pipe or draw-of pipe) must be within the secondary containment system.

From March 2020 anyone in Wales storing more than 200 litres of oil must replace their single skin tanks for a bunded tank. Find out more in our blog Oil Storage Wales – Beat the Deadline.  


Building Regulations

Steel oil Tanks connected to combustion devices like central heating and ovens must also comply with building regulations. These regulations cite fire separation distances – distances that your oil tank must be from boundaries that aren’t fire rated. Your tank must be:  


  •         At least 1.8m away from any part of a non-fire rated structure (e.g. buildings, eaves & windows)
  •         At least 0.76m away from non-fire rated boundaries (e.g. a fence)
  •         At least 0.6m away from screening (e.g. trellis & foliage)


However, with a fire-rated oil tank you can install your tank closer to (or even inside) buildings. Find out more in our Expert Guide to Fire Rated Oil Tanks.   Your tank must also be sited on a hardcore base at least 50mm thick which extends at least 300mm past the furthest point of the tank on all sides.   All of our steel oil tanks are manufactured to comply with steel oil tank regulations for the UK.    For any enquiries contact our sales team on 01889 567700 or use the online enquiry form.
