Unaudited net asset value per share at 31 August 2010

Caledonia Investments plc ("Caledonia") announces that its unaudited diluted net asset value ("NAV") per share as at 31 August 2010, calculated on a cum-income basis, was 1922p.

Due to the significant decline in the FTSE All-Share since its latest review of unquoted investment valuations at 31 March 2010, Caledonia had reduced its net assets by £47.8m at 30 June 2010, based on the 12.6% fall in this index. This reduction has been adjusted at each subsequent month end to reflect the change in the FTSE All-Share from 31 March 2010 to that point and at 31 August 2010 it amounted to £28.0m, representing the 7.3% decline in the index over the relevant period applied to the aggregate valuation of unquoted investments for which market prices were not readily available.

The monthly reported NAV per share, together with performance statistics and information on the valuation of principal investments, is available on Caledonia's website at www.caledonia.com.
