Don't forget we are only talking about P-bolts, funded by BCA and being installed by DCA - not any other anchors you want to place for your own use. The P-bolt installations are designed to be bomb-proof and pretty well permanent and to be installed on pitches which get a lot of use year after year. That's why we keep detailed records with a unique individual identifier for each bolt, the name of the installer who put it in, the date, the batch no. of both resin and bolt and exactly where it was installed in which cave, etc. That's also why we do check them regularly and would be able to follow up if, for instance, if it were found that a sequence of bolts which were all installed using a specific resin batch appeared to be failing.
DCA doesn't install any other type of anchor, so if you find a new pitch and want to put in your own bolts to explore - then that's up to you. But once it becomes a "trade route" with lots of people using it and all the wear and tear which that implies, then if there is a request, DCA will put in the P-bolts, funded by BCA and designed to last for many years - longer than almost all other fixings. In addition DCA has "approved in principle" installations which we knew would be asked for in the next few months so that there would be no delay once it had been agreed what would be bolted.
Maybe you have forgotten the situation which occurred in the 1980's and early 1990's: pitch heads peppered with useless anchors with stripped threads, everyone putting in their own anchors and 8mm bolts because they didn't trust what had been put in before. People going caving carrying bags of 8mm bolts to screw into the anchors already in place, hangers, a spanner and spare anchors and bolting kit because you never knew what duff anchor you might have to replace.
We can do rather better than that now and none of the P-bolts installed since the work was begun in Yorkshire and Derbyshire 1992 - over 20 years ago now - has failed. But it does take rather longer than 5 mins. to put one in.
