The state expressly stipulates that "account opening fee, installation fee and household entry fee" shall not be charged for various reasons. However, due to the large initial investment of natural gas companies, it is difficult to recover the cost only by selling natural gas (civil). Therefore, the initial installation fee has been cancelled in some areas of Guangdong (but the gas price is more expensive), and it is still being collected all over the country. Considering the practical difficulties of enterprise management, most local governments adopt a non-interference attitude.
Your place is 2270 yuan, which is relatively cheap. The initial installation cost of natural gas in most prefecture-level cities is about 3000 yuan. The initial installation cost of county-level cities in the north is around 2200.
