Natural Gas Bills in Turkey: Exceed Your Quota by Even One Cubic Meter and the Price Skyrockets Across Your Entire Consumption

As temperatures drop and natural gas consumption rises in Turkish homes, the tiered pricing system launched by Botaş on April 4, 2026 is now directly impacting the bills of millions of residential subscribers.

The system divides subscribers into two tiers: the first (Kademe-1) offers a subsidized rate for those who stay within their province's monthly quota, and the second (Kademe-2) applies a higher rate for those who exceed it. However, the mechanism contains a critical detail that escapes many subscribers: exceeding the quota by any amount — even a single cubic meter — means the entire month's consumption is charged at the higher tier rate, not just the excess portion.

Monthly quotas vary from province to province based on climate and historical consumption data, meaning a subscriber in Erzurum faces a different ceiling than one in Izmir. The company has not disclosed the specific figures for each province, leaving a gap in information that weighs heavily on subscribers.

The system was introduced during the cold season, which drives monthly bills to levels that pose a tangible burden on household budgets.
