Transfer Of Trading To AIM

Reliance Security Group PLC
30 June 2005



           Reliance Security Group plc ('Reliance' or the 'Company')

        De-listing from the Official List and transfer of trading to AIM

Introduction

The board of Reliance announces today proposals to de-list the Company's
ordinary shares from the Official List of the UK Listing Authority and to
transfer trading to AIM.

Reliance is an established market leader in the provision of contract security,
electronic surveillance, facilities management, support services and business
process outsourcing, employing over 12,000 people from a network of offices
throughout the United Kingdom.

Background

Reliance joined the Unlisted Securities Market of the London Stock Exchange in
March 1987. It moved to the Official List in September 1996 at a time when there
was no other appropriate market following the decision to close the Unlisted
Securities Market at the end of that year. Since then, the regulatory demands of
the Official List have become increasingly burdensome, particularly in recent
years, and the cost of compliance has escalated. Furthermore on the Official
List, companies of Reliance's size can struggle to attract the attention of
investors and the research analyst community.

The directors, therefore, feel that the Official List is no longer
cost-effective for the Company, particularly given Reliance's small free float
and low trading volumes. The directors also believe that AIM would be a more
natural home for Reliance alongside similarly sized companies, in a simplified
regulatory environment.

The Company remains committed to continuing to grow and develop the business for
the future and to maintaining high standards of corporate governance. It has
achieved an average annual compound growth rate in pre-exceptional earnings per
share of 18.5% over the last five financial years.

Further information on AIM

AIM was launched by the London Stock Exchange in 1995. The obligations of an AIM
company are similar to those of a company on the Official List with certain
exceptions. The significant ones are a reduction in the burden (and, therefore,
cost) of compliance and the removal of any requirement to maintain a fixed
percentage of shares in public hands (currently 25% of the issued share capital
under the Official List).

Since AIM opened in 1995, more than 1,600 companies have been admitted and more
than £15 billion has been raised in total.

Liquidity on AIM is currently provided by market makers who are member firms of
the London Stock Exchange who are obliged to quote a price in shares between
8.00 a.m. and 4.30 p.m. on business days. The directors believe that AIM has
demonstrated that it can provide a liquid trading platform for shares.

Companies whose shares trade on AIM are also treated as unlisted for the
purposes of certain areas of UK taxation, which can confer significant
advantages for private shareholders, primarily in the context of inheritance and
capital gains tax.

Transfer of trading to AIM

The Company will today give notice to cancel the listing of its ordinary shares
on the Official List and will apply to the London Stock Exchange for admission
to AIM. It is anticipated that the listing and trading of the ordinary shares on
the Official List will cease at close of business on 3 August 2005 being not
less than 20 business days from today's date. Admission is expected to take
place and dealings are expected to commence on AIM on 4 August 2005.
