There are 1.5 million users of home heating oil across the country, all of whom require an on-site heating oil tank to store the fuel they need for their home.

A number of factors will need to be considered before deciding on the final choice of heating tank, especially as this can involve an investment of more than £2,000 for a large, integrally-bunded oil tank.

Here are some of the key features to look for in a heating oil tank:

Steel or Plastic

While traditional home heating oil tanks are made from steel, modern-day versions made from plastic (moulded polyethylene) are becoming increasingly popular.

Plastic models are incredibly durable, despite their appearance, and can provide a relatively inexpensive heating oil tank option.

Metal tank options are also still a viable choice, but it is important to keep in mind that the oil-resistant coating on the tank’s interior will need to be maintained over the years.

Single or double skinned

Both plastic and steel heating oil tanks come in both single and double-skinned options, with the latter providing an extra layer of protection against contamination or damage.

While small, single-skinned tanks can start from £500, integrally-bunded tanks can be more than four times this cost. As a result the option you choose will be largely down to your budget.

However, whichever type of tank you opt for, both will need to have bund around it, which is designed to contain any loss of fuel to prevent pollution.

This secondary containment should be able to hold a minimum of 110% of the tank’s contents.


Heating oil tanks can vary in capacity depending on the make and model of tank. However, in general the average domestic tank capacities will range from 1,000 litres (220 gallons) and 1,360 litres (300 gallons), while domestic tanks are capable of carrying up to 2,500 litres (550 gallons).

The capacity you choose, will again be dependent on the individual needs of your household, perhaps your location e.g. if roads will be inaccessible to oil trucks at certain times of the year.
