Heating oil is the name commonly used for a petroleum oil that is used to heat homes with more traditional heating systems. Heating oil is burned in an oil burner to heat up water, and then the water is pumped around your home through piping and radiators to heat your house. There are over one million households in the UK that rely on heating oil instead of the national gas grid.
For more information about heating oil, check out out guide on home heating oil.
It’s important to effectively anticipate your heating oil usage to make sure you have enough oil to last the winter season. The minimum order for heating oil is 500 litres and domestic tanks typically range in size from 1,000 litres to 2,700 litres. Every home is different, so check your oil tank gauge to see how much oil your household consumes.
For more information on heating oil order quantities, check out our handy guide on How much heating oil should I order?
It’s best to order heating oil when your oil tank gauge indicates that your tank has less than a quarter of oil left in it. Avoid waiting until your tank is nearly empty to place a new order, as sometimes unpredictable weather can cause delivery delays. Heating oil is cheapest in the warmer months, so try stocking up on oil in the summer and ensure you’re prepared for the winter season.
There are two types of heating oil; kerosene and premium kerosene. Kerosene is a light, petroleum oil that is also known as 28-second oil and is the main type of heating oil that is used to heat homes in the UK. Premium kerosene is a higher quality oil that provides additional benefits to standard oil. At Certas Energy, we’re proud to offer Glowmax, our premium heating oil that is a cleaner burning fuel. Glowmax has been tested by AGA and is proven to improve the efficiency and performance of your boiler and cooker, while lowering the risk of breakdown. Whilst premium oils are more expensive than standard heating oils, the additional benefits that premium oils offer help customers to save money in the long run.
Heating oil can be stored in a plastic or steel storage container, such as a tank, drum, intermediate bulk container (IBCs) or a mobile container. If you need to install or replace an oil storage container at your property, make sure you use an OFTEC-registered engineer to ensure your installation is safe and compliant. There are strict fuel storage tank regulations in place to protect the environment.
Yes, we do. As well as supplying heating oil, we’re also experts in oil tanks and offer a range of oil storage solutions to suit your needs. Whether that’s giving your current storage container some TLC or helping you choose the right tank for your home from our range of top quality Kingspan oil tanks. Our friendly OFTEC-registered engineers can even fit and fill your new tank for you. All it takes is one call to sort it all.
Yes, we do. Our Smart Monitor helps you to take control of your heating oil usage and monitor your oil levels without having to manually check your tank. Simply log in to the Smart Monitor app to check your oil levels. For added peace of mind, we’ll also arrange automatic fuel deliveries when you’re running low, so you’ll never have to worry about your heating oil levels again.
In order to have a safe and efficient heating oil delivery, please make sure that our drivers have easy access to your oil storage tank. Leave gates unlocked or ensure the driver knows how to access your tank and that there are no obstacles blocking access to the roads or pathways leading to your tank.

The cost of heating oil in the UK fluctuates almost daily. There are several factors involved when determining the current price of heating oil. These range from political conflicts and foreign exchange rates to logistical issues such as weather and delivery costs. Heating oil can cost less during summer months and some customers do choose to top up when prices are lower. For more information on getting the best price for your heating oil, have a look at our guide to heating oil prices.
You can pay for your heating oil in monthly instalments or choose to pay upfront as and when you need additional heating oil. Certas offers two payment options to suit your budget and help you manage your heating oil deliveries and fuel costs.
You can choose to only pay for your heating oil as and when you need it. Our two payment options offer the choice of paying in monthly instalments or only paying for the amount of heating oil you need at the time you need it. You can order online or call us when you need your next fuel delivery and only pay for what you use.
Heating oil can be a cost effective way to heat your home. In rural areas where there is little or no gas supply, heating oil is an efficient and reliable fuel source. Electric incurs additional government charges and can be an expensive option whereas oil is well known for its efficiency.
The cost of heating oil can vary slightly in different areas. This can be due to local competition and companies undercutting one another. The most important factor when considering where to buy your home heating oil is the quality of fuel and level of customer service. Whilst your heating oil may cost slightly less from another provider, it may not last as long as a high quality heating oil.
Heating oil prices regularly increase and decrease according to many factors. The demand for heating oil in colder months puts a strain on supply thus causing prices to rise. Conversely, summer months generally see prices fall and this can be a good time to stock up if you have the capacity. Planning ahead can help cut fuel costs, as can paying in regular fixed monthly instalments. Our team can help you decide the best way to manage your heating oil payments.
As the price of heating oil can be so changeable, there is no set discount for bulk deliveries. It is advisable to regularly assess how much heating oil you have to ensure you don't run out, and to consider topping up during times when prices are lower. If you can gauge your usage and plan accordingly you will be able to make discounts when the price of heating oil is at its lowest
