The BG plc (Rateable Value) (Wales) Order 2000
Under paragraph 3(2) of Schedule 6 to the Local Government Finance Act 1988, the Secretary of State may by order provide in the case of non-domestic hereditaments to be shown in the central rating list for Wales that the normal rules of valuation for rating contained in paragraphs 2 to 2B of that Schedule shall not apply, and instead that their rateable value shall be such as is specified in the order or determined in accordance with prescribed rules. These powers are now vested in the National Assembly for Wales.
