How Cheapest Oil Works

Since 2008, we’ve been comparing and listing heating oil prices across Ireland every day. Nothing gets added (prices are commission free) and we don’t charge suppliers to list their prices. We are funded purely from adverts that appear on the website.

This means we are completely independent and impartial. We have no affiliation with any oil distributor – not now, not ever.

Many prices are updated every 15 minutes. Other prices are updated by oil distributors the moment they change. If a price has not been updated in a few days, it just means it most likely has not changed in that time.

Use the quotes to find a great deal and check the charts to find the best time to buy.
