How much to re-grip my clubs?

Depends on what you go for and how much tape you have. You can do it yourself very easily. Another option is to by yourself (Gamola is good) and see if the pro will put them on. Usually a bit cheaper and to be honest I wouldn't let AG within a Bubba drive of my clubs. Otherwise just take them to the club pro. I would say 9 irons for about £50-60 wouldn't be too bad. Some charge more, some less.
