What size oil tank do I need?

Oil tanks vary in size immensely, with 650 litres at one end of the spectrum and 10,000+ litres at the other end. The best size for your home will tend to depend on a number of factors.

Ideally you will know how many litres of oil you consume in a year, if you can get a tank that’s close to this, then you won’t need to refill it more than once a year. This will also allow you to take advantage of periods when there is lower fuel costs often in mid-summer. With a larger tank you can usually buy at a marginally cheaper unit price which can add up when buying larger quantities.

One of the key factors to consider is the location and amount of space you have available. If it’s a replacement oil tank, and it is going to be sited where you already have one, then it’s best to measure up and choose a tank to fit the space. This should help reduce the cost and the requirement for additional groundworks.

As a rough guide:

Typical 2 - 3 bedroom UK home would require a 1,000 - 2,000 litre tank
Typical 3 - 4 bedroom UK home would require a 1,500 – 2,500 litre tank
