Details

These orders were made under the market investigations provisions of the Enterprise Act 2002.

They require that:

  • exclusivity periods are limited to 2 years
  • the period of notice to end supply agreements must not exceed 42 days
  • suppliers must provide a telephone point where customers can be quoted prices
  • suppliers must annually provide the CMA with customer switching data
  • the whole tank transfer process must, subject to exceptions, be at no cost to customers

The Domestic Bulk LPG Market Order additionally requires that a tank transfer mechanism is set up with a pricing formula (see tank transfer calculator) and time limits. Existing suppliers are required to complete the sale of their tanks to new suppliers, and must take no more than 42 days.

The domestic bulk LPG tank transfer price calculator helps suppliers to reach quick agreements on the price of an LPG tank which is the subject of transfer from the incumbent to the incoming supplier. The calculator is amended annually by the Competition and Markets Authority (CMA).
