  additional 650,000 sq ft of self storage capacity when fully developed. 
  Detailed Planning Consents were granted during the quarter on Kingston and 
  Bristol South and we now have planning permission for six of the ten stores

James Gibson, Chief Executive Officer, commented:

"This is an encouraging performance given the slow start to the quarter and the 
current housing market and economic backdrop.  It reinforces our view that our 
formula of large, well located, highly branded, urban stores, with excellent 
customer service is the right one.

"We continue to believe that trading conditions will remain more testing than in 
previous years over the next 12 months, particularly in the winter period.  
However, these results bear out our often stated view that the Big Yellow 
business model, whilst not immune, is relatively resilient to economic slowdown.  
Current trading is in line with market expectations."

Notes to Editors

Big Yellow Group PLC is one of the leading and most dynamic self-storage groups
in the UK. It was founded in 1998 by Nicholas Vetch, Philip Burks and James
Gibson and listed on AIM in May 2000, moving to the Official List of the London
Stock Exchange in May 2002.

Big Yellow has expanded rapidly and now operates from 34 stores in London and
the South, and one recently opened in Leeds, with a further 10 stores in
development and of the 45, 35 are held freehold and one long leasehold. All the

being located within the M25 or in strong urban conurbations. When fully built
out the portfolio will provide approximately 2.7 million sq ft of flexible

The Group has pioneered the development of the latest generation of self-storage
facilities, which utilise state of the art technology and are located in high
profile, main road locations. Its focus on the location and visibility of its
buildings, coupled with excellent customer service, has created the most
recognised brand name in the UK storage industry.

As stated in the Preliminary Announcement on 10 May 2005, we will present our

September 2005 prior to the announcement of our interim results. We have not
included a pre-tax profit figure in these quarterly results to 30 June 2005 as
we have not completed our IFRS restatement exercise.
