How to find the cheapest home heating oil

If you use oil to heat your home, our 5 top tips cover how to find the cheapest kerosene and save money.

Heating your home using kerosene is more expensive than natural gas so it’s important to cut costs where you can, here are our 5 top tips to the biggest savings:

1. Shop around and compare prices

By comparing suppliers that deliver to your area, you can find the best rate each time.

This is made easy with cheapestoil.ie* who do all the leg work for you.

Simply select your location and you’ll get a list of local suppliers that you can sort by price. There’s a link to each supplier’s website you can click on and use their quick quote tool to get an exact price.

Playing around with quantities will also help you to find the best deal.

*Cheapestoil.ie only displays prices for kerosene, not gas oil which will be a different price.

2. Avoid seasonal hot spots

Although the price of oil is out of your control, demand is higher in the winter months which drives the cost up.

Avoid topping up your oil between October and February (particularly December) and opt for the spring or summer months instead.

Aim to do a big order around August/September that’ll last right through the winter.

3. Buy in bulk and reduce your orders

The more oil you buy in one go, the better the price per litre will be.

Avoid ordering less than 500 litres if you can, and opt for 1,000 litres or more for the best rates.

The fewer orders you make, the less additional charges you might face.

4. Buy online and check extra charges

It is nearly always cheaper to order online than over the phone.

As well as checking the price per litre and buying online, there are other costs to look out for including:

  • Delivery charges: These depend on the supplier and how rural your location is.
  • Credit card fees: e.g. 2% of the total or a flat rate per order of around €4.95 may be added.
  • Paying in instalments: Paying upfront is usually the cheapest option, so do this if you can.

5. Join a community heating club

This is where you team up with your local community to order your oil to get better rates.

To find one near you, search online for local home heating clubs or ask your neighbours.

Placing a much bigger order between you means you’ll get a better rate per litre of oil.

You could also save on delivery charges with your addresses being so near to each other.


Don’t forget about your electricity bill

If you haven’t switched your electricity provider in over a year, you’re probably on a standard tariff and paying more than you need to.

Home Heating Oil FAQ’s

How do I find my local community heating club?

If you’ve run a Google search and nothing has come up, the next step would be to ask around in your village.

If there isn’t one in your area, you could see how much interest there is for one and look into setting it up yourself.

How much kerosene would I use in a year?

The amount of home heating oil you use depends on things such as:

  • The size of your home/household
  • How often the heating is on
  • Whether you use kerosene to cook with too

An average 3 bedroom household uses around 1,500 to 2,000 litres of kerosene a year.

If your household is bigger or smaller than this, the amount you use is likely to go up or down.

Most households need to buy oil two or three times a year, depending on the tank size.

How much oil does a domestic tank hold?

The capacity of an oil tank varies greatly but an average size tank would hold around 1,000 to 2,500 litres.

If you’re not sure how much your oil tank holds, there should be a product label on the side or back of the tank confirming its maximum capacity.

Otherwise, you can take some measurements yourself and use a tank size calculator like this one.

What affects the price of kerosene?

The price of home heating oil changes frequently, being affected by things like:

  • Weather conditions
  • Seasons
  • Demand
  • Stock market oil prices
  • Exchange rates
  • Conflict where the oil is produced

What else is gas oil known as?

Gas oil is dyed green so that it’s not mistaken for regular diesel. It’s also known as:

  • Marked Gas Oil (MGO)
  • Green diesel
  • 35 second oil

It’s used in older outdoor burners only.

What else is kerosene known as?

Kerosene which is orange in colour, is also known as:

  • Jet A1 kero
  • Standard kero
  • 28 second oil

It’s used in modern burners and suitable to use inside e.g. in cookers and ranges.

What happens if I order too much oil for my tank?

If you’ve overestimated how much oil will fit in your tank, most suppliers will top it up to a safe level and only charge for the amount you’ve had.

Be aware though that the rate you pay per litre is likely to go up by having a smaller amount.
