                       DEREGISTRATION OF SHARES

        Pursuant to the Registration Statement on Form S-8, file no. 333-132117
(the "Registration  Statement"),  which was originally filed on March 1, 2006,
Hanson  PLC,  a public  limited  company  under the laws of England  and Wales
(the  "Registrant")  registered 3,500,000 ordinary shares of £0.10 each
(the "Ordinary  Shares"),  to be offered under the Hanson Building Materials
America Retirement Savings and Investment Plan or the 401(k) Retirement Plan
of Hanson Building Materials America (the "Plans).

         On May 15,  2007,  the  Registrant  and  HeidelbergCement  announced
that  they had  reached  agreement  on the  terms of the acquisition  of the
entire  issued  and to be issued  share  capital  of the  Registrant  by
HeidelbergCement.  The  acquisition  was implemented by way of a English court
approved  procedure known as a scheme of arrangement (the "Scheme of
Arrangement"),  which became effective on August 23, 2007.  Under the terms of
the Scheme of  Arrangement,  the Ordinary  Shares were  cancelled  and each
holder of Ordinary  Shares of the  Registrant  became  entitled to receive
1100 pence in cash for each Ordinary  Share (or a loan note in certain cases).
As a result of the Scheme of  Arrangement,  the  Registrant  has  terminated
all  offerings of its Ordinary  Shares under its existing registration
statements (including the Registration Statement).

         In accordance with an undertaking made by the Registrant in the
Registration  Statement to remove from registration,  by means of a
post-effective  amendment,  any of the securities  that remain unsold at the
termination of the offering,  the Registrant  hereby amends the Registration
Statement to deregister all Ordinary Shares  registered  under the
Registration  Statement that were not sold prior to the date hereof.



                                    SIGNATURES

         Pursuant to the  requirements of the Securities Act, the Registrant
certifies that it has reasonable  grounds to believe that it meets all of the
requirements  for filing on Form S-8 and has duly caused this  Post-Effective
Amendment No. 1 to the Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in London, England on September 4,
2007.
