Access to secret rates. Pricing is set by the lender against the risk it sees in the file. What is negotiable is structure — the tenure, the scope and cap of a personal guarantee, whether collateral changes the shape of the offer, and the conditions that have to be satisfied before disbursement. Those are worth negotiating on either route, and it is where most of the value sits.
Comparing two offers is straightforward. It is not, and this trips up borrowers going direct as often as anyone. A flat rate quoted on the original amount produces a smaller-looking number than the effective interest rate for the same facility. Two offers can only be compared once both are on the same basis, and the cheaper-sounding one is frequently not the cheaper one.
Government-supported facilities need an intermediary. They do not. Facilities under the Enterprise Financing Scheme are applied for through a participating financial institution, which you can approach yourself, and that institution still makes its own credit decision. Two participating institutions can reach different answers on the same file — which is a reason to know which one to approach, not a reason to need someone to approach it for you.
