Every fuel tank has a functional lifespan, after which it needs to be replaced. The total lifespan of your commercial fuel tank depends on its location, maintenance and a wide variety of other factors.

If your fuel tank is nearing the end of its functional lifespan, our OFTEC trained team is here to remove it and install a replacement. Our full fuel tank replacement service covers the process from beginning to end, from removing your previous tank to safely installing a new one.

We’ll also safely dispose of its contents, providing you with a certificate of disposal and all other essential paperwork.

As fuel tank specialists, our business is ISO 9001 and PAS 43 certified, allowing us to perform all of our services to the highest levels of quality. To learn more about our fuel tank replacement services, please continue reading below or contact us now on 0800 799 9739.

Our Commercial Fuel Tank Replacement Process

No two fuel tanks installations are identical, meaning our team will take a personalised approach to removing and replacing your existing fuel tank.

Our process begins by understanding your requirements. Our team will visit your commercial or industrial site and review your fuel tank’s history. We’ll then create a method statement and risk assessment for the removal and replacement process.

After this, you’ll receive a detailed quotation for the removal and replacement process. Once we get to work, we’ll complete the entire process with minimal disruption to your day-to-day work processes, allowing you to run your business or organisation without any interruptions.

Hazardous Materials Removal

Even if your old fuel tank’s gauge says that it’s completely empty, it’s still possible for flammable, hazardous gases and materials to remain inside. For a safe removal and replacement process, our team will need to drain and dispose of these materials before removing the old fuel tank.

We safely dispose of all hazardous materials through a process that’s compliant with all waste disposal and environmental regulations. You’ll receive a certificate of disposal supplied for your old fuel tank, as well as a consignment note for liquids that are disposed of.

Commercial Fuel Tank Removal

As part of the fuel tank replacement process, we’ll need to remove your old, unused fuel tank from your site. Depending on the tank’s size and location, we’ll remove it in one piece using a range of excavation and removals equipment, or cut it into pieces for a simpler removal.

We have a range of options for commercial and industrial oil tank removal. Our team will review all available removal options and suggest the most cost-effective, efficient option for your site.

Commercial Fuel Tank Replacement

After safely removing your old fuel tank, our OFTEC trained team will install a new, replacement tank on your commercial or industrial site.

We offer a wide range of fuel tanks. Depending on your needs and budget, we can recommend a model that’s suitable for your business or organisation. After installation, your new oil tank will be covered by a six year warranty backed by OFTEC for confidence and peace of mind.

Construction and type of tank

Oil storage tanks can be constructed from carbon steel, medium density polyethylene or glass reinforced plastic. The shape and size (rectangular, horizontal cylindrical or vertical cylindrical) should be selected by taking into account the available space for installation and the capacity required to serve the appliance(s).

Underground tanks should only be considered where no other options exist, as they are difficult to inspect and leaks may not be immediately obvious. Information on the installation, decommissioning and removal of underground tanks can be found in the Environment Agency guidance note PPG 27.

Environmental protection

To minimise the risk of pollution from an oil spill, nondomestic oil storage tanks exceeding 200 litres must be provided with secondary containment (bunding). This can be achieved by installing an integrally bunded tank or by constructing a concrete or masonry bund, to CIRIA Report 163, around a single skinned tank. The bund must capable of containing at least 110% of the oil storage tank’s capacity.

It is important to provide facilities for measuring the quantity of oil in a tank. Sight tubes can be used as long as they are located within a concrete or masonry bund built to CIRIA Report 163. They cannot be used on integrally bunded tanks and therefore, electronic or hydrostatic contents gauges are recommended.

NOTE: Greater technical information regarding environmental protection requirements applicable to oil storage tanks can be found in other OFTEC Information Sheets entitled “The Control of Pollution (Oil Storage) (England) Regulations 2001, “The Water Environment (Oil Storage) (Scotland) Regulations 2006”, and “The Control of Pollution (Oil Storage) Regulations (Northern Ireland) 2010”, as applicable.

Fire protection

Externally sited non-domestic oil storage tanks should comply with the fire separation requirements in Column A of Table1. Where these separation distances cannot be achieved, a screen wall must be provided between the tank and the hazard (either a building or boundary) in accordance with the specifications in Column B.

Additionally, where a tank contains more than 3500 litres any openings in the walls between 1.8 and 6m away from the tank should be fitted with 1hour fire resisting glazing or 1hour fire resisting self-closing doors.


Steel oil storage tanks, when properly installed, may require infrequent maintenance during their useful life. However, they should be regularly inspected for any signs of corrosion or leakage.

Plastic oil storage tanks usually require little maintenance. However, it is important that they are also inspected for any signs of leakage, discolouration and deformation.

It is recommended that oil storage tanks and their ancillary equipment are inspected on an annual basis by an OFTEC Registered Technician.


The need to provide suitable bases and supports for oil storage tanks is of paramount importance for reasons of both safety and environmental protection. Tank bases should be:

  • Adequate for the weight of the tank;
  • Non-combustible, imperforate and level;
  • Constructed of concrete, paving stones or stonework;
  • Large enough to extend 300mm beyond all sides of the tank.

Further information on preparing base foundations, erecting piers and laying platforms can be found in OFTEC Technical Book 3.

Internal Oil Storage

An oil storage tank sited inside of a non-domestic building must be fully enclosed within a fire resistant chamber. The walls, roof and doors of the chamber will require a fire rating of between 30 minutes and 4 hours, depending on the class of oil storage and the capacity of the tank. Consideration should also be given to access, ventilation, fire extinguishing equipment and electrical safety within the chamber. Further information can be found in OFTEC Technical Book 3.

Finding an OFTEC Registered Technician

The OFTEC website enables you to locate your nearest Registered Technicians. OFTEC Registered Technicians are appropriately qualified and insured to work oil fired equipment.

You can also find a list of local Registered Technicians under the OFTEC logo in the ‘Heating Engineers’ section of your local pages. For further information on oil heating and cooking, please see www.oftec.org.
