Unaudited net asset value per share at 31 July 2010

Caledonia Investments plc ("Caledonia") announces that its unaudited diluted net asset value ("NAV") per share as at 31 July 2010, calculated on a cum-income basis, was 1925p.

Due to the significant decline in the FTSE All-Share index 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. At 31 July 2010, this adjustment was reduced to £25.3m, calculated by applying the 6.7% decline in the FTSE All-Share index between 31 March and 31 July 2010 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.
