Bunded Oil Tanks – Compliant, Safe & Reliable Fuel Storage

Bunded Oil Tanks have become the standard of choice for Oil Storage central heating because of updated regulations for fire safety and the environment. This double skin protects the area around it from the environmentally hazardous oil inside. The outer skin forms a backup in case the inner tank fails because if oil leaks into the ground it can severely damage the local ecosystem and your wallet!

How does Secondary Containment work?

Creating built-in Secondary Containment commonly involves starting with the plastic single skin variant of the tank. This inner tank, therefore, stores the diesel oil along with the gauge and other equipment. Two parts often form the bund, a larger lower bund of 110% capacity of the tank and an upper ‘lid’. So, to create the bund, the manufacture attaches the lower ¾ of the bund to the original tank. The bund is complete when the two are attached to each other with the hatch built into the upper bund.

What does Oil Heating do?

Oil Central Heating provides all the hot water to your home. Unless you are using an alternate source of water heating. That means your warm showers, washing machine, and dishwasher are all relying on your oil heating tank. Your boiler will burn the oil when it is needed to heat your home too. Keeping your tank clean will always ensure that your boiler receives high-quality oil.

Slimline Bunded Oil Storage Tanks

Sadly, the size requirements of Plastic Bunded Oil Tanks are larger than their single-skin counterparts. However, with our incredible range of slimline oil tanks, you can squeeze them in where you need to!

Regulatory Bodies and Markings for Bunded Fuel Tanks

Nearly all of our bunded tanks have OFCERT assigned numbers. That means they are approved by OFTEC for installation by a Certified Engineer because we only recommend compliant installations.

Heating Fuel Bunded Storage comes in all shapes and sizes and we can find one that’s right for you! All our tanks are CE Marked and meet British Standard 5410 for Plastic Tanks and BS 799-5 for Steel. So you can rest assured that they only come from trusted manufacturers. 

The great Brands we Stock

We stock fuel storage from manufacturers that we’ve been working side by side with for over a decade. That’s because they only provide real quality from right here in the UK. Thanks to work by the Environment Agency, OFTEC and Building Regulations, fuel storage in the UK is safe.

Smaller bunded heating oil tanks like the 350 Litre Harlequin & 650 Litre Carbery Tanks provide entry-level storage for smaller properties. These lower capacity tanks also provide for low oil consumption holiday homes or Airbnb.

For most home installations, we recommend the SL1000BT found here. Slightly larger sizes include an 1100 Litre Slimline model from Carbery that promise 48 Hour Delivery!

Bigger Fuel Tanks for Heating the Home

A 1200 Litre solution comes from Titan Oil Tanks where we recommend their EcoSafe ES1225. This robust Slimline Oil Tank comes with a Contents Gauge & Alarm included! 1300, 2500 Litre & 5000 Litre tanks are available in just about any shape, size or brand. 

Harlequin, Tuffa and Turners all provide solutions up to 10,000 Litre Oil Tanks. Plus they provide Bunded Steel Tanks and Plastic Bunded Oil Storage solutions with Cabinets.

The Safety of Bunded Fuel Storage

We recommend safe Oil Storage for heating systems at all times. However, in environmentally sensitive areas it is a legal requirement that can be discovered with one of our Free Assessments. The Outer Skin forms a protective 110% capacity bund around the fuel tank’s plastic single skin container. Bunded tanks catch oil from cracks, spills in the internal fittings or overfilling! So they protect our water supplies and homes from contamination.

Installation of Bunded Oil Tanks

Thanks to our OFTEC Qualified Engineers we can offer Installation of any of these Bunded Fuel Tanks at your home. Enquire here!

Oil Storage Installation Regulations

Oil Fired Technical Association – OFTEC Provide a checklist for the installation of oil storage that states a Bunded Oil Storage is required when the tank:

  • Is in Jersey, Guernsey or the Isle of Man
  • Is in Wales and installed after 15th March 2016
  • Capacity is over 2500 Litres
  • Is within 10 metres of controlled water
  • Located where a spillage could run into an open drain or to a loose-fitting manhole cover
  • Within 50 metres of a borehole or spring
  • Over hard ground or hard-surfaced ground that could enable spillage run-off to reach controlled water
  • Located in a position where the vent pipe outlet is not visible from the fill point
  • Supplying Heating Oil to a building other than a single-family dwelling
  • Located within an England ‘Groundwater Source Protection Zone 1’
  • Is subject to any other Potential Hazard individual to the site

An oil tank located in a flood risk area or an area exposed to high winds will require a Tank Restraint. This prevents the risk of tank tipping and causing damage to itself and potentially leaking oil.

The Environment Agency requires that all of these standards are met to protect the land from contamination. They require that tanks adhere to either British Standard 5410 or the OFTEC OST T100 specification. For metal tanks, they require that the tank meets British Standard 799-5 or OFTEC OFS T200 specification.

Fire Protection for Oil Installations

Fire risks are also an important concern of ours when we install any fuel storage tanks. That’s why we adhere to OFTEC’s Fire Hazard checklist that states Fire Protection is needed if the Oil Tank is located within:

  • 1.8 metres of a non-fire rated building or structure (less than 30 minutes of fire protection)
  • 760mm of a non-fire rated boundary (less than 30 minutes of fire protection)
  • 1.8 metres of non-fire rated eaves (less than 30 minutes of fire protection). That’s 1.8 metres from the part of a roof that meets or overhangs the wall of a building
  • 1.8 metres of a construction opening in a building i.e. a Door or Window
  • 1.8 metres of a flue termination i.e. An exhaust duct, pipe or opening in a chimney from a burner appliance of fireplace
  • Or on a base which does not extend to a minimum of 300mm around all sides of the tank
