Bunded Oil Tanks – Help & Advice

These are the standard of choice these days because current regulations for fire safety and the environment often require secondary containment. This double skin protects the area around it from the hazardous oil inside.

How does Secondary Containment work?

This is done by commonly taking the plastic single skin variant and attaching it to the lower ¾ of the bund. The bunds are often produced in two parts a larger lower bund and an upper ‘lid’. The two are then attached to each other to form a complete bund with a hatch.

Inside the bund, there will be the tank that holds the oil with the gauge and other equipment.

Slimline Oil Storage

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

Regulatory Bodies and Markings for Fuel Tanks

Nearly all of our bunded tanks have OFCERT assigned numbers, therefore, they are approved by OFTEC for installation by a Certified Engineer.

Bunded Heating Fuel storage comes in all shapes and sizes and we can find one that’s right for you! All our tanks are CE Marked so you can rest assured that they come from trusted manufacturers.

These are Storage Solution Brands that we’ve been working with for over a decade. They provide real quality from right here in the UK.

From smaller bunded heating storage like the 350 Litre Harlequin & 650 Litre Carbery Tanks. These are entry-level tanks for smaller properties or low usage.

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

The Safety of Bunded Fuel Storage

We recommend safe Oil Storage for heating systems in environmentally sensitive areas. The Outer Skin forms a protective 110% capacity bund around the fuel tank’s plastic single skin container. By catching any cracks or spills in the internal fittings or walls they protect our water supplies from contamination.

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.

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)
  • Within 760mm of a non-fire rated boundary (less than 30 minutes of fire protection)
  • Within 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
  • Within 1.8 metres of a construction opening in a building i.e. a Door or Window
  • Within 1.8 metres of a flue termination i.e. An exhaust duct, pipe or opening in a chimney from a burner appliance of fireplace
  • On a base which does not extend to a minimum of 300mm around all sides of the tank
