Fitting an Oil Tank

On the face of it, fitting an oil tank can seem like an easy project to undertake. Once you have selected the correct oil tank, it’s important to conduct a lot of research into the project to ensure you complete the installation correctly and avoid any costly penalties.

In this guide, QuickTanks explains the process of fitting an oil tank and outlines the oil tank installation regulations to help you avoid falling foul of the rules. You may also be asking, can I install my own oil tank? Let’s find out.

Can I install my own oil tank?

It is possible and legal to install your own oil tank as long as you adhere to all the regulations. However, we strongly recommend hiring a licensed professional, such as an OFTEC-registered engineer, to complete the oil tank installation process for you.

Are there any risks associated with fitting an oil tank?

Fitting an oil tank carries certain risks. One of the main concerns is the potential for leaks when adding the oil. Moving the tank can further weaken areas of its structure, leading to possible damage or splits. Fuel spills can contaminate the surrounding soil or nearby water sources, resulting in environmental harm and possibly incurring regulatory penalties.

That’s why using a professional is so important to minimise the chances of anything going drastically wrong. The risk of oil spills, pollution and failure to meet the strict regulations are all reduced. All three of those could be extremely costly due to replacements, penalty fines and the risk of fire damage to other buildings.

Oil tank installation regulations

It might be frustrating and daunting to read about oil tank installation regulations, but they are in place for a reason. The oil tank installation regulations are there to keep you and your neighbours safe, reduce the risk of fires and limit environmental damage. Firstly, you will need to check whether you need planning permission. 

Planning permission for oil tank installations

Before fitting an oil tank, you will need to work out if you need planning permission. You will not need planning permission if…

  • The oil tank is less than 3m tall
  • The oil tank is less than 2.5m tall if it is within 2m of a boundary
  • The tank isn’t being stored in front of the principal elevation fronting a highway
  • No more than half of the area surrounding the original house would be covered by additions or other buildings

You will need planning permission if you are fitting an oil tank for a listed building regardless of the mitigating factors listed above. 

There are then several things you must consider to ensure you comply with the regulations. 

  • The oil tank must have a protective fire guard if it is located above ground
  • Your oil tank needs extra protection, such as a bunded tank, if it is located near groundwater 
  • A fire valve must be present where the pipe enters the building

Tanks with a capacity larger than 2,500 litres or tanks located in environmentally sensitive areas must be bunded. Bunded oil tanks have an extra layer to prevent oil leaks and spills.

How close can an oil tank be to a house?

The next thing to consider when complying with the oil tank installation regulations is the location and the base. The tank must be located where the risk of fire spreading to nearby structures/buildings is minimal. 

  • 1.8m away from non-fire-rated eaves of a building
  • 1.8m away from a non-fire-rated building or structure (e.g. garden sheds and tents)
  • 1.8m away from openings (such as doors or windows) in a fire-rated building or structure (e.g. brick-built house/garage)
  • 1.8m away from liquid fuel appliance flue terminals
  • 0.76m away from a non-fire-rated boundary, such as a wooden boundary fence
  • 0.6m away from screening (e.g. trellis and foliage) that does not form part of the boundary.

If the oil tank cannot be positioned at the appropriate distance, a protective barrier must be constructed. This barrier should withstand fire for at least 30 minutes. This requirement should be taken into account if you are relocating an oil tank.

The base must be able to support the full weight of the tank to avoid leakages and costly repairs that could set you back. Fuel oil weighs one tonne per 1,000 litres, and you will also have to consider the tank’s weight.

The base must be impermeable and inflammable. Therefore, using concrete is highly recommended. The oil tank must be set on a level bed and the perimeter of the base should extend out beyond the edge of the tank by 300mm. If you have opted to use pre-cast concrete slabs, they must be 50mm thick and laid on a hardcore base. If you have decided to use a concrete base cast, it must be 100mm thick. 

When choosing a location and creating the base, consider things such as oil delivery access, weathering, and maintenance tasks. The government website offers more information about oil tank regulations.

Fitting an oil tank process

After reviewing the oil tank regulations, the next step is to install the oil tank. The engineer must ensure that the base is properly prepared. If any adjustments are needed, the engineer should be capable of making those modifications.

The oil tank will then be moved into position and connected to an oil supply line. Any emergency equipment required should also be installed around the oil tank.  The engineer will ensure everything works properly before leaving the site clean and tidy. 

Oil tank maintenance

Regular oil tank maintenance ensures it runs safely and will help maximise its lifespan. It is a good idea to schedule an annual inspection with an OFTEC-registered engineer.

The tank must be cleaned regularly to ensure the oil is in good condition. Vent and fill pipes must be tested to ensure everything is flowing correctly. For a complete guide on oil tank maintenance, check out our essential oil maintenance tips.

How long does it take to fit an oil tank?

The length of time it takes to complete the job depends on various factors, such as environmental conditions and whether or not you need an old oil tank removed first. However, a professional should be able to fit an oil tank within a day.
