How does the Connected oil monitor work?

1. Fit the monitor onto your tank and activate the monitor. (the monitor will search for mobile phone signal)

2. The monitor will measure how many millimeters of oil is in your tank. This reading will be taken at the same time every day.

3. Using the tank dimensions you’ve provided on your tank account, the system then converts the millimeters into volume.

4. Your oil levels will appear on your tank account

Why does my monitor not read the exact measurement of my heating oil?

We want to be transparent on how our oil monitors work with the Connected service. Our monitors are there to track your heating oil levels, the data we receive from the monitor tells us when to order your top-up. If there is a substantial difference between the oil in your tank and the oil levels on your tank account this may be due to one of the two reasons below. 

Our oil monitor gives an estimation of your oil levels due to the monitor rounding litres to the nearest 10.


The wrong tank dimension has been provided.

When setting up the Connected monitor we ask for your heating oil tank dimensions. It is important these measurements are correct as they can affect the oil levels we show you on your tank account and also your monthly estimations.

To help you find out your tank size, we have created the video Setting you up with ease. 


The Connected monitor is too short or too long for your oil tank.

We have a few different sizes of oil monitors that are used for our Connected service. To make sure we give you the right information about your oil levels, we send an oil monitor based on the size of your heating oil tank.


If the wrong oil monitor is placed on your tank, it can give inaccurate readings of your oil levels and may affect your automatic top ups.  

If there is an issue with my monitor what should I do?

Our monitors are reliable and are tested to work efficiently for the Connected Service. However, If you think there may be an issue with your monitor, you can contact one our Connected customer service agents by calling 0333 016 2099.

Group Savings

Save more with Group Savings

Typically, when you buy more than 2,000 litres of heating oil, you will pay a lower price per litre than if you were buying 500 litres.

This is because it is cheaper for Suppliers to deliver one large ‘bulk’ order to one area, than it is for them to deliver several smaller orders in different areas.​
