UGI is looking to increase rates for all its customers. The natural gas company has filed a request with the Pennsylvania Public Utility Commission to increase its rates for residential, commercial, and industrial customers. If approved, residential customers would see an 8.5% hike that works out to about $7 more a month for the average home. Commercial customers would see an increase of 17.4% while industrial rates would go up by 18%. UGI says the rate hike is needed for system improvements.
