imho install time is greatly dependant on prior knowledge and research, most of which i found on here, special thanks to Kevin and Lazy d.

With Lazys spare inlet manifold i was able to fit the front end kit in a weekend, just needed Kevin to run all the wires into the relay box and ecu by the battery, a far better idea than running wires all over the place. I beleive he has now quoted the relevant pin out numbers on here somewhere.
Then fitted the rear end kit( dunut tank in spare wheel well so diff to those in the guides) which took me longer to do without the formentioned knowledge in that area, not helped by too short a length of polly pipe and haveing to modify the bracket.

in short, be certain what you do before you do it. Esp if you need the car on Monday morning.
Ask on here or visit an approved installer as to whats required for safety certs, there are some good ones out there but some on here have had bad experiences with the gents from the lpga.
Re certs, lpga approved install certificates are only issued by proffessional installers on their own work, you wont get one of those if you diy. You will get a safety certificate from them for diy which, as said, IS sufficiant for insurance.( Direct line implied to me diy installs are not covered, they simply where not aware that a safety cert for diy existed, and said that only approved install certs would sufice. They where wrong and i have the appology letter to prove it

)
Of course, I still have the spare manifold by the way.

Considering lpg is an economy item, diy is the only way to go as pay back will be acheived in less than half the time re a pro install.
