Identifying When It’s Time For An Oil Tank Replacement
With 1.5 million people relying on oil or fuel tanks across the UK, the last thing that you want to worry about is a damaged or out-of-action oil tank!
This could be costly if you miss the key signs for identifying when to replace an oil or fuel tank.
At LV Fuel Services, we help our customers assess when oil or fuel tanks are coming to the end of their lifespan.
In this guide, we will share some of the signs we recommend to look for when your oil tank is coming to the end of it’s usability cycle.
We will also cover what to look for when choosing to replace your oil tank.
How Long Do Heating Oil Tanks Last?
With proper care, a heating oil tank can last anywhere from 15 to 25 years.
Nothing lasts forever, especially not oil and fuel tanks. A product’s predicted lifespan is a great indicator when assessing its current condition.
With proper care, such as our inspection and maintenance services, your oil tank will keep running in good condition and run until the end of its lifespan.
Can/ Should We Repair An Oil Tank?
When deciding whether to repair or replace an oil tank, consider its age and condition.
Oil tanks over 15 years old or showing significant damage often warrant replacement.
Evaluate the cost of repairs against the long-term savings of a new oil tank, especially if repairs exceed 50% of the replacement cost.
Additionally, ensure compliance with current regulations, as newer tanks typically offer improved safety and efficiency.

When to Replace an Oil or Fuel Tank?
Aside from assessing the age of an oil or fuel tank, some other ways to identify when it’s time to find a replacement oil tank are as follows:
Clogged pipes
If you notice regular interruptions to fuel flow, this will likely mean the pipes are no longer fit for purpose. Cleaning can often resolve the issue, but this will eventually mean an oil tank replacement is needed. If not, over time, temporary problems can lead to permanent issues.
Fuel inefficiencies
If you start to notice that your consumption is different from what you normally experience, this could be a sign of internal issues. Over time, fuel tanks can suffer from rusting and blocking of pipework, which affects their functionality.
Rusting or exterior wear
Whilst the outside of an oil tank is likely to be the first part showing signs of damage over time, it’s important to pay attention if this worsens. Corrosion or dents can lead to internal issues that can only be resolved by installing a new oil tank.
Leaks or damage
This might seem obvious, but many people think they can simply patch up an area of damage and that things will be resolved. However, if the issue is bad or repeated, it could be a sign that a full oil tank replacement is needed.
Unstable legs
If your oil tank is no longer being properly supported, fuel release will not be efficient. Wobbly or damaged legs indicate the need for a new product.
When replacing your domestic or commercial oil tank, there are several important factors to consider.
How To Choose Right Oil Tank:
When choosing an oil tank it’s important to consider the right oil tank for your needs. If you’re a domestic customer you will likely need a smaller oil tank.
Whereas commercial and industrial customers will need larger oil tanks.
For domestic customers, oil tank sizes typically range from 1,000 to 4,500 litres, with common choices being 1,000 or 2,000 litres, depending on the household’s heating needs and available storage space.
For commercial customers, oil tank sizes vary more widely, from 4,500 to over 45,000 litres, based on the business’s fuel consumption rates, operational scale, and storage capacity requirements.
Another thing to consider is material of the oil tank. When it comes to choosing an oil tank there are several types to choose from.
- Steel oil tanks: for their robust strength and long-term durability. Steel oil tanks are ideal for high-demand environments but requiring regular maintenance to prevent rust.
- Polyethylene oil tanks: are a popular choice for their lightweight, corrosion-resistant properties. They are easier to install and maintain, particularly in residential settings.
- Fibreglass oil tanks: Fibreglass oil tanks offer a middle ground, combining the corrosion resistance of polyethylene with the strength of steel. Fibreglass oil tanks are suitable for both underground and above-ground installations, making them versatile for different environments. They are less likely to corrode and can handle various chemical contents, making them ideal for long-term storage solutions in both domestic and commercial settings.
- Underground oil tanks: These tanks are typically made from fibreglass or coated steel and are installed below the ground to save space and reduce visual impact. Underground oil tanks are suitable for both domestic and commercial applications, providing a discreet storage solution. However, they require careful installation to prevent leaks and contamination, and regular inspections are essential.
- Above-ground oil tanks: Above-ground oil tanks can be made from steel, polyethylene, or fibreglass and are easier to install and maintain than underground tanks. They are often used in both residential and commercial settings where space allows. Above-ground oil tanks are accessible for regular inspections and maintenance, making it easier to detect and address issues such as leaks.
Oil Tank Replacement Regulations and Permits:
Site preparation for oil tank replacement involves several critical steps to ensure a smooth and safe process.
Initially, conduct a site assessment to plan the excavation and determine the ideal location of the oil tank, considering accessibility and compliance with local regulations.
At this stage, we can carry out a special assessment, where we can advise based on your specific oil tank requirements.
The next oil tank replacement preparation step would be to safely remove the old oil tank, including proper disposal of any remaining oil and thorough cleaning to prevent environmental contamination.
Finally, the site will need to be prepared and excavation of the site area if necessary, ensuring a stable and level base for the new oil tank, and installing any required safety and containment systems.
The Oil Tank Replacement Process:
- Replacement of your old oil tank for a new oil tank requires careful positioning to ensure it is level, stable, and accessible for refuelling and maintenance, while also complying with local regulations.
- Securely connect the tank to the fuel lines, ensuring all fittings are tight and leak-proof to prevent any fuel leakage.
- Implement necessary safety measures, such as installing a spill containment system and leak detection alarms, to quickly identify and mitigate any potential issues.
- Finally, perform a thorough inspection of the entire installation to confirm that all components are properly installed and functioning, ensuring the system’s overall safety and efficiency.
We would strongly advise consulting with an oil tank replacement and installation specialist to ensure the oil tank is correctly and safely installed.
Underground Oil Tank Replacement
Underground oil tank replacement is a complex process involving excavation, soil testing, and adherence to strict environmental regulations.
This makes it generally more costly than above-ground oil tank replacements.
The potential for soil and groundwater contamination from leaks necessitates thorough assessments and compliance with specific regulatory standards.
While underground oil tanks save space and offer weather protection, they require careful maintenance and monitoring to ensure safety and compliance.
It is almost always the best advice to get an underground tank removed professionally to avoid any issues.
Oil Tank Replacement Costs:
The oil tank replacement costs can vary depending on a number of factors, as this involves setting up a new tank on your property.
Replacement costs can very depending on a number of things:
- Type of oil tank and the size.
- If excavation is required or if the site needs significant preparation work.
- If you need an oil tank permit/planning application.
- Disposal and decommissioning of the old tank.
- It’s also wise to budget for potential upgrades, such as spill containment systems or advanced leak detection devices, to ensure compliance with safety and environmental regulations.
The costs associated with oil tank replacement can vary widely, for both domestic and commercial oil tanks.
