Check a billAverage gas usage per month in the UK
Average gas usage is a useful sense check only when you remember that gas is highly seasonal. A rough annual benchmark can help, but winter heating patterns, hot-water demand, insulation and property size can push a perfectly valid bill far above a national “typical” number.
Why gas averages are especially easy to misuse
Gas demand swings with weather. A cold month can sit far above a flat monthly average while still being entirely plausible. That is why you should compare with similar months or seasons where possible, not just with a simple annual division.

Frequently asked questions
Is gas usage spread evenly across the year?
No. It is usually heavily weighted toward colder months.
Does a high winter gas bill automatically mean something is wrong?
No. But you should still check the reading type and billed period if the jump is unusually large.
What should I compare against first?
Your own past gas kWh for similar seasons is usually more useful than a national average.
