ok then - Your the Harbinger!!
As I understand the implementation of this agreement (and I've read far too much to back over all the old stuff again), it was indeed brought into being by the DfT as a variant on the "Home Computer Initiative". It has also been modified to a large degree by the Trading Standards.
Although on paper this is a lease, in reality it isn't a lease. If it were a lease then in a situation where an employee was dismissed, it would be impossible for the Lessor to argue in court that the Lessee had to pay the outstanding lease for an asset that they did not have use of, unless this was a Contract Purchase (HP) in which case the Lessee (the employee) would keep the asset (the bike).
The fact that if it goes over the £1000 threshold, that a Consumer Credit License is required should also go to show that in practice this is not a lease, but a form of purchase.
The 5% value was passed to the CTC I believe (
heres one ref to it), and is merely meant to be a notional value, an almost "good will" payment to secure the asset out of the lease, after all there is no such thing as a second hand Bike market, there are no companies such as Glasses (Guides), Henley (Coding) or CAP (black book / red book), companies that are in business purely because they monitor the second hand car market.
The reason that all of these rules exist is to get around the laws regarding taxable benefits, leasing laws and asset purchasing. For many companies their car fleet is one of the biggest expenditures of all, if they have 100 or so £20k cars that they replace every 3 years, thats £2m every 3 years, so if they can find a loophole, they will, and they will use it too.
So I guess what I am saying is that the spirit of these agreements is very important, and thats why I personally have not heard of any cases where the 'Harbinger of Doom' was ever present, nor needed to be.
