Plastic Oil Tanks

Our plastic heating oil tanks exceed all UK oil storage regulations. Renowned for strength, reliability and quality, they are suitable for domestic, commercial and agricultural use.

Plastic Oil Tanks Information

Our range of plastic oil tanks are available in single skin, bunded and with fire protection.  Our smaller capacity plastic oil tanks (from 1350 to 2500 litres) are the only tanks on the market offering integrally fitted fire protection. The bunded plastic oil tank range reaches a maximum capacity of 15,000 litres and we’re currently developing a new slimline plastic tank with a small capacity below 1000 litres which will be perfect for domestic or small-scale business use.  


Tuffa’s plastic tanks make a great material for liquid storage as they are highly durable, corrosion resistant and UV stabilised. They also offer a great affordable alternative to our steel range. Additionally, the tanks are rotational moulded in one-piece increasing the overall strength and making for faster lead times.

Should I choose a plastic or steel heating oil tank?

Plastic and steel heating oil tanks each have their own benefits. Steel heating oil tanks are designed with a life expectancy of over 30 years and can be manufactured to tailored specifications and to exact dimensions. This makes them perfect for replacing old tanks within the same space. Our plastic tanks are a great affordable alternative to steel. They are also lighter than steel making them easier to move when empty. Our bunded oil tanks are designed with a life expectancy of 20 years or more. Furthermore, these are the only plastic tanks on the market available with integrally fitted fire protection in capacities up to 2500 litres.  



Our heating oil tanks can be a long-term investment. The bigger the capacity tank you order, the more money you can save on kerosene, albeit at the greater initial cost of the tank. Bulk buying kerosene has numerous benefits. Kerosene prices fluctuate (sometimes wildly) 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.  


A higher capacity oil tank 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 our bunded oil tanks are designed with a life expectancy of at least 20 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 highestt possible capacity for your budget and available space.  


While we think that bigger is better when it comes to tank sizes, here is a rough guide of tank capacities for domestic use:  




Our bunded 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.  



The Control of Pollution Regulations (Oil Storage) (England) Regulations 2001 dictate 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.
  • Automatic overfill prevention devices must be used when it’s not practical to observe the vent pipe or tank.


Wales, Scotland and Northern Ireland

With an increased focus on protecting the environment oil storage regulations are becoming increasingly strict and regulations in Wales now require all new oil tank installations with a capacity over 200 litres to be bunded. All new oil tanks installed in England, Scotland and Northern Ireland must be bunded when the tank has the capacity to store above 2,500 litres in capacity.

Building Regulations   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 which 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).


Your plastic oil tanks 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.  

Our product range means that we have the right tank for you to make sure you comply with regulations for your tank’s size, location and usage. Contact us to discuss our fire protected heating oil tanks.
