Reading and submitting gas meter

How do I read my gas meter? It’s showing as “08699” (see attached image) but when I go to submit online, there’s only space for 4 numbers. I’ve read conflicting things about including the zero at the beginning. Thanks.

If the system is asking for 4 digits, it would appear that your meter is registered as an imperial one (measuring in cubic feet).
Your picture confirms that it is actually a metric meter (cubic metres), for which the system would expect 5 digits, including any leading zeros.
