When it comes to PIR's, I'm known as a stickler, a reg's junkie, I go to the far end of the proverbial fart but I'd still expect at least 15 circuits a day from a competent inspector!
Nothing wrong with a bit of selective editing lol! I did say WORST case - no information, etc.
Assuming this is a first visit, and no records are available - I'm not about to put my guys under pressure missing things.
We've been stung like that before, happily being assured there are records available, turn up, not even a fuse way labelled, and several boards later, the hour we allowed per circuit looks distinctly like a giveaway. Not to mention waiting time where we've been promised the IT is or will be completely shut down for our visit - and then had to wait up to two hours while they figure out how to shut down servers that have run forever (and suddenly discovering the UPS ain't so "U" any more as the batteries fried in 1988!!!!).
Seriously - a hundred and twenty ways of no information costs time and money. So would eighty. On the bright side, they're never going to face another PIR with no information.
A guide of five circuits an hour is a pricing guide, and not a work throughput guide - that time has to include admin beyond the site too - the cost of creating circuit legends, plans, records, and so on.
To be honest, we're on the cheap end locally - South East generally - Central London will see a hundred quid a circuit easily.
As for "hourly rates" - that's purely market forces - overheads, cost of business, plus mark up. As I say, we're not by far expensive for the primary areas we work in. I guess it helps to have an understanding of the area the job is in when it comes to these things.
Again, it was a ballpark that was asked for, and a ballpark that was given - based on what was given.
Jus' sayin'
