There is no honest figure to put on it, and CW Asset Finance does not publish conversion statistics. What can be said is that machinery is frequently bought on finance rather than cash, so a buyer with no funding route in front of them has one more reason to delay or look elsewhere.
The argument is about removing friction rather than creating demand. A customer who wants a machine but is weighing the capital outlay may find a monthly cost easier to justify against the work the machine will do. That conversation either happens at the point of sale or it does not happen at all.
Be careful how you put it. Nothing you say should suggest finance is guaranteed, that a rate is available before a lender has decided, or that spreading the cost is cheaper than paying outright. And remember that the sales material itself counts: “finance available” or “from £X per month” on a website, brochure or forecourt board is a financial promotion, which must be fair, clear and not misleading and generally needs approval by an authorised firm. This is the point dealers most often trip over.
This is general information, not legal or compliance advice, and your position depends on your customer mix.
