(b) any other circumstances which appear to the Secretary of State to be relevant.

(3) The new basic rateable valuation so determined for each Gas Board shall be the rateable valuation of that Board's undertaking in respect of the year for which it is so determined and, subject to the provisions of this paragraph, shall for the purposes of this Schedule be the Board's basic rateable valuation for that year and any subsequent year.
