Bristol-based integrated agency Studio Six has been appointed to the newly formed BP roster for creative services.

The agency has worked with BP since 2001, but in response to "changing market conditions and the opportunity to achieve efficiencies", BP procurement has selected a roster of creative agencies.

Studio Six is currently working with the Castrol and BP brands on internal communications.

"We have not been formally advised who else is on the roster," said Ruth Clarke, marketing manager at Studio Six: "It is all still very new with contracts being finalised etc so for us it is Business-as-usual for the time being. That said, we have just been advised to expect a brief through their new centralised process."
