Cycle Solutions don’t issue vouchers, it’s order only, Cycle Scheme is the LBS option:
Cycle Solutions use both an internet shop (and their own shop in Swansea) and you can use local shops, as per Cyclescheme.
Rate varies between suppliers but most are taking the piss given diminishing margins in the bike trade.
It can take 12-18 months of meetings, phone calls, tenders, legal documents, etc, before your employer sets up a scheme with a provider. The provider, if they are any good, will then provide print or electronic marketing, B2B support, B2C support, process the admin (hire agreements, etc), provide a suitable end of scheme process, and so on. They may provide road shows or other local support. This all costs money and time and needs staff.
An average order is £6-700, so they make maybe £100 per order if it goes through a local shop.
The staff of that local shop get a customer walking in who wants to spend money and is easily persuaded to upgrade, hopefully returning to spend more money. Not many LBSs complain about that.
