The electrician could write it out there and then or (as I do) go home and do you a nice printed one; in which case it could be a couple of days plus postage, if far away. He should have told you, though.
Then there is the notice from NICEIC which, I think, will be about four weeks.
The NICEIC have a 28 calender day limit from completion of the work, plus you could be looking at another wedge of time on top of that depending on the speed of your local authority.
Had one job I notified (on the day of completion) yet it took 6 weeks to get the final cert. The LABC had the NICEIC notification within a week, but didn't issue their cert for another 5 weeks.
