Domestic Heating Oil Explained: Your Questions Answered

April 9, 2025

If your property isn’t connected to the gas grid, home heating oil is likely a key part of how you keep warm, especially during the colder months. It’s a popular choice for rural and off-grid homes, offering an efficient and reliable alternative to mains gas. However, many homeowners still have questions about how heating oil works, how it's stored and delivered, and what to expect from a domestic oil supplier.

Whether you're new to oil heating or looking to optimise your setup, this guide answers the most frequently asked questions to help you make informed, confident decisions about your fuel supply.


What Is Domestic Heating Oil?

Domestic heating oil is a liquid fuel used to power oil-fired boilers and heating systems. Kerosene is the most commonly used domestic heating oil, often used in rural homes and properties without access to mains gas. Heating oil is stored in a tank on your property and burned in a boiler to provide central heating and hot water.

 

It’s known for its energy efficiency, cost-effectiveness, and suitability for off-grid homes.


How Is Heating Oil Delivered?

When you order heating oil, a domestic oil supplier delivers it via a specialised tanker. The driver connects a hose to your external tank and fills it with the volume you've requested.

Delivery times vary depending on location and time of year, with higher demand during the winter. Some suppliers offer express oil delivery options or automatic top-up services to prevent you from running out.


How Much Heating Oil Will I Need?

The average UK household uses between 1,000 and 2,000 litres of home heating oil per year. Your actual usage will depend on the size of your home, how well it’s insulated, the efficiency of your boiler, and your heating habits.

It’s a good idea to monitor your tank level regularly, especially in colder months, to avoid unexpected shortages.


How Do I Store Heating Oil Safely?

Your oil tank should be installed in a secure, well-ventilated outdoor location, ideally with bunded (double-walled) protection to guard against leaks.

Regular maintenance is key. Check for signs of rust or damage and have the tank inspected annually. Your domestic oil supplier may also offer tank monitoring or replacement services to help you manage your system more effectively.


Can I Save Money on Heating Oil?

Yes, there are several ways to keep costs down. Ordering in bulk, buying during off-peak months (typically spring and summer), and joining a local buying group can all lead to savings. Choosing a trusted domestic oil supplier who offers competitive rates and dependable oil delivery is also important.
