                        IMPACT OF WEATHER COSTS ON AVIVA

Following the recent floods in parts of northern and central England, Aviva plc
('Aviva') estimates the cost of claims relating to these floods to be in the
region of £175 million, which will impact the group's general insurance results
in the first half of 2007. This initial estimate is subject to uncertainty,
particularly in relation to average claim costs, and does not include allowance
for further claims that could arise should this current spell of bad weather
continue.


Aviva remains committed to meet or beat a combined operating ratio of 98%.
