More Information on Oil Tanks:
Can I fit a single skin oil tank? Or will I need a bunded oil tank?
Another frequently asked question here at Easymerchant Limited, and we hope this handy guide will answer it for you:
For some domestic oil tank installations fitting a single skin oil tank can be a suitable solution. This applies to England & Scotland only, and NOT Wales.
In any situation, an oil storage risk assessment should be carried out to determine the correct tank and installation. This can be carried out by an OFTEC approved engineer.
In brief a Bund or Bunded Oil Tank is required in domestic situations if:
- Your tank is in Wales.
- You are storing over 2500 litres.
- Your tank is near an open drain or loose-fitting manhole.
- Your tank is within 10m of controlled water such as a river, stream etc.
- Your tank is located where any spillage could travel over hard ground to reach controlled water.
- Your tank is located within 50m of a borehole, spring or well.
- Your tank vent is not visible from the fill point (such as an extended fill point)
- Your oil use is for a building other than a single-family dwelling.
- Any other unique hazards to your site.
All domestic oil tanks over 2500 litres need to be bunded.
All non-domestic oil tanks over 200 litres need to be bunded.
Carbery Bunded Tanks consist of a ‘tank within a tank’. Fuel is stored in the tank, whilst the outer tank acts as a fail safe significantly reducing the probability of an environmental contamination episode. In the UK and Ireland, Bunded Tanks are used mostly in agricultural and domestic installations, and meets most requirements at industrial, commercial and institutional installations.
Please note the following information is specific to the regulation of oil storage in England. The regulations in other UK countries are alike, but we encourage you to confirm the details with the local authority before making any purchase.
Domestic oil storage tanks are easy to forget about once installed, however, the Environment Agency and the FPS (Federation of Petroleum Suppliers) recommend that homeowners have their oil tanks checked once annually by an OFTEC inspector. Ensuring that your oil storage tank is in good condition and meets the oil storage regulations is important once you consider the impact of an oil leak. If you breach the oil storage regulations, you may even be prosecuted.
A oil or fuel storage tank is believed to be for domestic use if it holds less than 3500 litres, supports a single family dwelling (i.e. a house, not a block of flats), and the oil is used for heating and/or cooking purposes.
If you are just storing oil in a tank on your land there are some principles that still apply as set out in the Oil Storage Regulations from the Government. These include meeting with the building regulations for oil tanks.
Bunded Oil Tanks & Environmental Protection:
It is true that oil spills from national tanks are infrequent, however, they are equally expensive and damaging to clean up. It's best to reduce risk in the first instance. The bunded oil tank regulations illustrate cases where you will be required to install and use a bunded oil tank to provide additional protection. A bunded tank is simply a tank with another skin (a'bund'). To be compliant the bund must hold 110% of the tank's capacity, and be impermeable to water and oil (i.e. should not permit water/oil in or out).
You will need a bunded oil tank if the answer is yes to any of the following questions:
Is your oil storage tank installed in a place where:
- The tank vents can not be seen by the delivery person since the tanks are too far away from where the tanker could park?
- Oil spills could run into a drain or manhole cover?
- It is within 10 metres of rivers or lakes (any inland fresh water or shore )?
- Oil spills could run over ground until it reaches inland water that is fresh, water sources or coastlines?
- It's within 50 metres of a potable (drinkable) water supply, like a spring, borehole or well?
Building Regulations and the Installation of Oil Tanks:
Building Regulations that are local should be complied with by all petroleum storage tank installations. OFTEC registered technicians are able to self certify their oil tank installations in England and Wales, without approval from the Local Authority Building Control. Should you choose work you'll be required to arrange inspection which will have time and cost consequences.
the regulations regarding extensions and the addition of Oil Tanks stipulate that you DO NOT need planning permission if the following are met - unless it is a listed building, in which case you will need planning permission:
- No more than half of the area surrounding the house would be covered by additions or other buildings
- The tank is Not being Saved in front of the principle elevation fronting a highway
- The max. Height in complete is 2.5m if it's within 2m of a boundary The max. Height in complete is 3m
Further caution is needed when:
- The tank is to be stored above the Floor, it will need a protective Guard to guard from fire
- The oil storage tank will need extra protection Against spillage and leakage if there is ground water near
- A fire valve should be fitted where the pipe will enter the building
