What is a Single Skin Tank?
A Single Skin Oil Tank consists of a single container in which fuel is stored. Unlike Bunded Oil Tanks and Bunded Fuel Tanks, Single Skin Oil Tanks incorporate no secondary containment whatsoever and in the event of a spill, a pollution incident will occur.
Single Skin Oil Tanks are not suitable for the storage of fuel at commercial, industrial or institutional premises; or at domestic installations with an installed capacity of over 2,500 litres – unless installed within a suitably bunded area. For all other installations, an Oil Tank Risk Assessment must be undertaken by a competent person prior to installation and in accordance with the requirements of OFTEC Technical Instruction Book 3.
What is a Bunded Tank?
A Bunded Tank simply consists of an ‘oil tank within a oil tank’. In the event of a spillage, surplus liquid will collect in the outer tank (or ‘bund’), thus averting a pollution incident. Bunded Tanks are now required at commercial, industrial, institutuonal, commercial and most domestic premises.
How close to a boundary can I place an oil storage tank?
How close to a flu outlet can I place an oil tank?

Internal oil storage tanks should never be installed in a habitable area and if installed internally, should always be contained within an enclosed chamber. Detailed requirements exist for internal oil storage installations. For more information contact your local Building Control Officer or OFTEC.
Are any plastic oil tanks sold by TankDepot.co.uk suitable for direct burial underground?
No tank currently supplied by TankDepot.co.uk is suitable for direct underground burial.
What materials are plastic oil tanks manufactured from?
What are the base requirements for plastic oil tanks?
All plastic oil tanks must be installed on a flat, level and fire resistant base capable of supporting the weight of the tank when fully laden. If concrete slabs are used they should be a minimum of 50mm thick. The base should extend at least 300mm beyond the widest points of the tank and fully support the base of the tank in its entirety. Piers are not suitable for this purpose and can cause irreperable damage to the tank.
Can I fit a sight gauge to a Bunded Tank?
There is a two pin type socket fitted to my Harlequin oil tank. What is this for?
This permits an LRC enabled delivery driver to plug in his overfill prevention equipment and is not for consumer use.
Are plastic oil tanks designed to protect from the damaging effects of sunlight?
Yes. Every oil tank sold by TankDepot.co.uk is manufactured from a material which incorporated UV inhibitors. These prevent UV rays from permeating the structure of the tank, thus preventing fuel degredation.
Are plastic oil tanks supplied by TankDepot.co.uk suitable for the storage of fuel for aviation use?
No.
Are plastic oil tanks fitted with sludge valves / cocks?
No. Today, no openings (other than the tank outlet) are permitted below the maximum level of fuel in any oil tank. This reduces the risk of accidental spillage. In the event that contaminants (e.g. water) need to be removed from an oil tank, they should be removed by an appropriately licensed contractor via the inspection apperture fitted to each tank.
I have discovered the presence of water in my oil. How do I get this removed?
Please contact your local fuel distributor who will be able to provide advice on how best to remove it.
Are plastic oil tanks suitable for use with oil fired cookers?
Yes.
On warm days there is a slight smell of oil from my oil tank. Why?
This is perfectly normal and is simply the fuel venting through the weatherproof vent fitted to the oil tank.
Are plastic Oil Recycling Banks / Waste Oil Tanks suitable for the disposal of petrol or any other highly flammable liquid?
No. For advice on how to dispose of petrol and any other similarly dangerous liquids, please contact your local authority.
