How to Check Your Heating Oil Level: A Simple UK Guide
Checking your heating oil level regularly is one of the simplest ways to avoid running out of fuel, particularly during the colder months when your boiler is working harder.
Whether you have a traditional oil tank gauge, use a dipstick or have a smart tank monitor installed, knowing how much heating oil you have left makes it easier to plan your next delivery.
In this guide, we'll explain how to check your heating oil tank, how to estimate when you'll need more fuel and how Rix Petroleum can help you keep track of your heating oil.
Why Is It Important to Check Your Heating Oil Level?
Unlike homes connected to the mains gas network, properties using heating oil need to manage their own fuel supply.
If your tank runs empty, your heating and hot water could stop working until you arrange another delivery. Running out can also mean your heating system needs attention before it restarts.
Regularly checking your heating oil level helps you:
- Avoid unexpectedly running out of heating oil.
- Plan deliveries before your tank gets too low.
- Understand how quickly your household uses fuel.
- Budget for future heating oil orders.
- Identify unusual changes in your fuel level.
During winter, it's particularly important to monitor your tank because heating oil consumption can increase significantly during colder weather.
How to Check Your Heating Oil Level
There are several ways to check how much heating oil is left in your tank. The method available will depend on the type of tank and equipment you have installed.
1. Check Your Heating Oil Tank Gauge
Many domestic heating oil tanks have a gauge that provides an indication of how much fuel remains.
Common types include float gauges, sight gauges and electronic gauges.
A float gauge typically displays the approximate level of heating oil in the tank, often showing readings between empty and full.
To check your gauge:
- Locate the gauge on your heating oil tank.
- Read the current level.
- Compare it with previous readings to understand your usage.
- Consider arranging a delivery before your fuel level becomes too low.
Remember that tank gauges provide an estimate rather than an exact measurement. Older or damaged gauges may also give inaccurate readings.
If you're unsure whether your gauge is working correctly, ask a qualified professional for advice.
2. Use a Dipstick to Measure Your Heating Oil
Some heating oil tanks can be checked manually using a suitable dipstick.
This involves measuring the depth of the heating oil inside the tank.
However, dipping is only appropriate where the tank has a designated, safe access point and the manufacturer permits this method.
If your tank is suitable for manual dipping:
- Use a clean dipstick designed for measuring heating oil.
- Follow the tank manufacturer's instructions.
- Record the measurement.
- Use the tank's capacity chart, where available, to estimate the litres remaining.
Never force open tank fittings or remove components that aren't designed for routine access.
If you're uncertain how to measure your tank safely, contact your local depot or a qualified heating oil tank professional.
3. Use a Smart Heating Oil Tank Monitor
For homeowners who would prefer not to check their tank manually, a smart heating oil tank monitor offers a more convenient way to keep track of fuel levels.
These devices monitor the amount of heating oil remaining in your tank and provide readings through a connected system.
At Rix Petroleum, our Tank Monitoring service helps customers keep track of their heating oil levels without having to regularly visit their tank.
With regular tank level readings available through an app, it's easier to understand how quickly you're using fuel and when you may need to arrange your next delivery.
This can be particularly useful if your tank is difficult to access, you're away from home regularly or you simply want greater visibility of your heating oil supply.

How Much Heating Oil Is Left in My Tank?
Knowing whether your tank is half full is useful, but it doesn't necessarily tell you how many litres you have remaining.
For example, a tank with a capacity of 1,200 litres that is approximately half full would contain around 600 litres of heating oil.
However, this calculation assumes the gauge accurately represents the usable tank volume.
Different tank shapes and gauge types can affect how accurately a reading translates into litres.
If you're unsure of your tank capacity, check the manufacturer's information or ask a qualified professional.
How Much Heating Oil Should I Order?
The amount of heating oil you need depends on your current tank level, tank capacity and expected household consumption.
Your heating oil usage can vary depending on:
- The size and insulation of your home.
- How often your heating is switched on.
- The efficiency of your oil boiler.
- Whether heating oil is also used for hot water.
- The number of people living in your property.
- Outdoor temperatures.

When Should You Order More Heating Oil?
It's generally better to order heating oil before your tank becomes critically low rather than waiting until you're nearly empty.
During winter, colder temperatures can increase demand for heating oil, and delivery availability may vary depending on your location and local conditions.
Checking your tank regularly allows you to plan ahead and arrange a delivery with more flexibility.
If you're unsure how much fuel you have remaining, check your gauge or tank monitor and consider your household's typical consumption.
At Rix Petroleum, the minimum heating oil order is 500 litres, so it's worth considering your available tank capacity when planning your next delivery.
What Happens If You Run Out of Heating Oil?
Running out of heating oil can leave your home without heating or hot water if your boiler relies on oil for both.
It may also cause your boiler to lock out, and some heating systems may need professional attention before they can be restarted.
If you run out of heating oil:
- Switch off your heating system if advised by the manufacturer's instructions.
- Arrange a heating oil delivery as soon as possible.
- Follow your boiler manufacturer's guidance before attempting to restart it.
- Contact a qualified heating engineer if your boiler fails to restart or requires attention.
The best way to avoid this situation is to monitor your fuel level and order before your tank runs too low.
