Isn't there some sort of amendment service for the CAA charts?
Jeppessen has a section on their website describing all the changes to the VFR+GPS chart set. If you diligently (and I know it's a big IF) apply all the changes listed there, you should always have an up to date chart. To the point where you should even not need to buy a new one every year. (Although that's probably the easiest anyway.)
