Narrative:

On initial climb out of egll we departed runway 9R on SID southampton 3J. Initial altitude given for the SID is 6000 feet 6000 feet was properly set in the MCP. My position in the cockpit was that of the relief pilot. As we climbed out of 5100 feet I reminded the flying pilots the transition altitude would be 6000 feet as per the SID. This reminder inadvertently prompted the flying pilots to reset the altimeters before leaving TL6000 resulting in an altitude deviation of 500 feet once leveled off. We were given a climb clearance within 90 seconds after level off with no further altitude deviation. There was no comment from ATC. As we climbed out the crew talked about the discrepancy and later reviewed the standard procedure of waiting to be cleared above TL6000 to reset the altimeter. There was no traffic or safety issue due to the slight deviation.
