              BP moves to weekly online Trading Conditions Update

March 19,  2007


BP announced today that it is updating the process by which it informs the
market of the trading conditions which it is currently experiencing. Previously
BP published a quarterly Trading Update shortly after the end of each quarter.
This once per quarter update to the market is now being replaced by a new weekly
Trading Conditions Update, available on BP's website at www.bp.com/
tradingconditions. The Trading Conditions Update will normally be posted on our
website each Monday at 14:30 (UK time).


The new BP Trading Conditions Update provides a weekly update of information on
key marker prices for crude oil and natural gas, and indicator refining margins.
In addition to the markers and margins covered in the previous quarterly
Trading Update, information on additional marker crudes, differentials and
indicator refining margins is provided. Historic data on oil and gas marker
prices back to 2002 and refining margins as far back as 1990 are also now
available on our website at www.bp.com/tradingconditions.

BP's annual guidance for 2007 on expected production, capital spending, tax rate
and Other Business & Corporate was provided in the 2006 Results & Strategy
Update of February 6, 2007. This is available at www.bp.com/strategy

BP's Stock Exchange Announcement covering the first quarter results for 2007
will be released as previously announced on April 24, 2007 at 07:00 (UK time)
