Frequently Asked Questions
A bunded oil tank is simply a tank within a tank, with fuel being stored within the inner tank. The reason behind the design is to ensure that there is no fuel loss due to the occurrence of a spill or like for like incident.
All stations mentioned above are suitable for the storage of BioDiesel blends up to B5.
Most plastic bunded oil tanks come with a 10 year manufacturers’ warranty and when properly installed and maintained can last for many years beyond its expiration date. Fuel pumping and tank equipment usually comes with the standard manufacturers 1 year warranty.
Yes the fitting kit comes complete with a 1/4 turn isolation or shut off valve so maintenance can be carried out on the fitting kit or supply pipe even when your heating oil tank is full of oil.
Generally a single skin oil tank should NOT be installed when it is within 10 metres of a water source, 50 metres of a water well or spring and where spillages could run into a drain or manhole (please click for more info & related products).
Internal oil storage tanks should always be contained within an enclosed chamber, but never installed in a habitable area. Detailed requirements for the installation of oil storage tanks within habitable buildings and domestic garages can be acquired from OFTEC.
A good rule of thumb to follow is if the tank is less than 3500 litres, it should not be placed within 760mm of a combustible boundary e.g. a fence, assuming that there are no flu outlets or buildings between the tank and the boundary.
No tank should be fitted with sludge cock or valves as legal requirements state clearly the risks concerned if there are any openings below the maximum level of fuel in the tank.
There are a number of precautions and measures you should follow with the incorporation of sight gauges including:
It is recommended by OFTEC that all oil tank installations, whether it is a reinstall or new installation complies with regulatory requirements and should fall within the scope of current building regulations.
Yes. It is important to replace older metal tanks as condensation, amongst other things, on the inside of the tank can cause corrosion, resulting in leaks and an expensive clean ups for the tanks owner.
Only if it is necessary – you should always aim to utilise the space that you have in the most effective way.
Harlequin Oil Tanks are suitable only for the storage of...
The Oil Storage Regulations England applies to all above ground oil storage containers holding a capacity of over 200 litres and all private domestic oil tanks that hold a capacity over 3,500 litres.
A two pin type socket is used to enable the tank to connect to a SecuTech LRC Overfill Prevention System.
Yes, with the correct fitting fill point, manhole access, inspection point or cabinet access, your oil tank can be locked and left secure.
Yes there is. The maximum liquid temperature is 55°C.
The liquids that can be monitored used the Apollo tank guage includes:
The need to replace filters will depend upon a number of factors: the recommended period between filter replacements, the brand of fuel station/filter and the type of fuel, station you have installed.
The Control of Pollution (Oil Storage) (England) Regulations 2001 regulates English above ground oil storage and covers petrol, diesel, vegetable, synthetic and mineral oils.
The requirements are different for those in England and in Scotland. Find out by cliking on the question.
Controlled waters refers to all water that is below the ground in the saturation zone and in direct contact with the ground. This can include canals, rivers, streams, lakes and estuaries.
Yes, there are lots of differences between the types of oil storage tanks and these are also available in a variety of sizes.
OFTEC is an independent body that accesses and certifies engineers, whilst overseeing technician’s training who are providing services in commissioning, servicing, installation and plant operation that entails the use of oil fired equipment.
Knowing the size of your oil tank and its capacity will make ordering fuel a lot easier and you can find out the capacity of your tank by looking at the product label, which should be placed at the front or side of the tank on plastic tanks.

A single skin oil tank is a single rotationally molded container where fuel is stored and it does not benefit from the addition of a secondary containment. They are suitable for small domestic installations where bunded oil tanks are not a legal requirement.
When installing a plastic oil tank bear in mind these requirements...
Most oil tanks are manufactured from Medium Density Polyethylene (MDPE), which boasts excellent chemical and impact resistance properties.
If your tank has been manufactured using UV inhibitor materials then your fuel should be kept from harm.
The fire protection provided by the base is to help prevent the tank itself from becoming overgrown and in turn to help protect against fire spreading across the ground to the contained fuel from another source.
Sight gauges are a potential leak point at any installation and are known at most installations to contravene Building and Environmental Regulations.
Condensate is the result of the tank warming up during the day and then cooling at night and will form in any oil storage tank. It is perfectly normal and in single skin oil tanks it will collect in the base of the tank and in bunded oil tanks it may additionally collect between the inner and outer tanks.
Oil that is to be removed from a storage tank is considered a waste oil and should be removed by a professional.
There are a number of standards that your oil tank should comply with including the BS EN ISO 9001. All plastic and steel oil tanks should be manufactured to OFTEC, OFS T100 (plastic) and OFS T200 (steel BS799-5) standards.
This should be assessed by an OFTEC engineer and if the following is found, a bunded tank will be required on you site.
