I don't want anyone to misinterpret me. Jim is absolutely right, there are many regs these days with a 2 year service interval, but in most cases manufacturers still require an inspection on the off year (especially true if you are dealing with warranty kits). So I always suggest that they be sent in annually to have either of them done. A reputable technician should know how to look up the history or ask the right questions to know what the reg needs. BUT, because a reg works even though it hasn't been serviced in X years doesn't necessarily mean it's a good Idea to dive it. I like to air on the side of caution and stick to what the manufacturer recommends, because for me it comes down to liability.
If a reg is outside of it's service window, please don't ask me to certify it "safe" to dive, because I will not.
If you can't do a quick inspection and bench test of my regs and certify them as safe, I would not want you working on them. The safety has to do with performance and mechanical condition, not tearing pages off of a calendar. If that is your criteria, you don't truly understand what it is you are working on. You are simply checking boxes on a list. And if you DO understand but are taking this stance anyway, you would be knowingly ripping me off by potentially providing service I don't need.
Edit: I picked up a set of Dacor regs for basically nothing, mostly just looking for the gauges. (Parts kits are not readily available, and although some people do manage to piece together workable parts solutions I am not interested in doing so). Before stripping them down, I had a tech at one of the LDSs in the area look at and assess them. He inspected, tested, and adjusted them. We had a frank discussion about their condition.
We have no idea when they were last serviced before I got them. I have had them for 4 years. They breathe fine, hold a steady IP, no leaks, good cracking pressure. They have saved several dives, and remain safe to use. They certainly don't come close to your calendar criteria though.
