Is this BMW brake wear excessive?

My local BMW dealer (Vines of Guildford - highly recommended) is getting my wife's 5 series E61 2008 520d touring's brakes looked at on a warning light. It needs new front pads and discs (lipped), cost £504. Had front disks/pads replaced in 2010 two years from new at 30K miles and now at 60K miles, so twice in its 4-year life. She really does drive very carefully and always in the countryside. Dealer says that pads are more aggressive now, but is this excessive wear?
Could be. Pads are now metallic so do wear and cause corrosion to the discs themselves.
