How do I read my gas meter?

A gas meter allows you to understand your gas consumption, so knowing how to read your gas meter can help you manage your usage. Here’s how to read your meter, and the benefits of doing so.

Why do you need to read your gas meter?

If you don’t know much gas you actually use, your energy supplier may estimate your usage.

This could mean you pay too much or too little for your energy, and may later result in a hefty bill.

By taking accurate gas meter readings and submitting them to your supplier, you’ll only be charged for the energy you’ve actually used.

Knowing how much gas you actually use will also make it easier to find a better deal and switch to a new supplier.

To read this type of meter:

  1. Read the numbers on the dials from left to right, ignoring the last red dial or any dials without figures or hands.
  2. If the needle is between two figures, take a note of the number the dial has just passed.
  3. If the figure is directly over the figure, say 5, write down that figure and underline it.
  4. Look at the figure underlined. If one of those numbers in the sequence is followed by a 9, reduce the underlined figure by 1 (so the underlined 5 becomes 4).

4. How to read a prepayment gas meter

  1. Press the blue button on your meter, which will change the display from your remaining credit to your meter reading;
  2. When your reading appears, make a note of the numbers; and
  3. Ignore any numbers appearing in red.

What to do after taking your gas meter reading

Compare your actual usage against your last estimated bill and see if you have been paying too much or too little.

If you’ve been overpaying, submit your latest gas reading to your supplier and they should refund you the difference.

If you have been underpaying because your usage is higher than the estimate, contact your supplier to discuss your options. They may be able to spread the extra cost over a few months.
