We shall see as we are looking to Tender for a new provider. Maybe someone that gives a better deal to the buyer.
This is slightly off thread, but you may be interested:
I have managed our scheme for 2 years, and put together a business proposal to our board of directors evaluating a variety of schemes. If it's any use to you,
Halfords came out on top over a number of other schemes including CycleScheme, Bikes for the NHS and creating our own scheme etc.
This isn't to say that it will be best for you and your organisation, but they suited us in a number of ways, mainly because they exist as a business in their own right. They don't need to take a profit from savings the scheme should be passing onto employees. The cycles also remain property of our company, so we have been able to adapt to changes in the scheme in the way we saw fit - for example altering the way that change of ownership payments are made to benefit the employee, not the scheme provider.
Our organisation also has a large geographical footprint, so a national chain offering the same products at the same prices with the same warranties was also essential for ensuring all our staff had the opportunity to realise the same benefits.
They offer a special order line so that more knowledgeable (fussy) cyclists can choose from a much wider variety of brands than those instore. They also stock the Boardman range which are pretty much the best value around IMHO (if you're not too snobby

)
EDIT: Obviously the downside is that Halfords aren't really a cyclist's best friend, but we haven't had any problem with build quality so far.
