Clearing & relationship banks
Clearing and relationship banks are the deposit-funded high-street institutions that hold a company's accounts and lend alongside the day-to-day banking relationship. For a lower-mid-market borrower they are the natural first stop for cleanly bankable senior debt and working capital: the keenest pricing and security in the market, decided through centralised credit, with the relationship — not the deal alone — doing much of the work.
How to use this baseline
A borrower should look here first when the requirement is vanilla (senior term debt, an RCF or overdraft, or modest acquisition finance) against a profitable, established company with a clean balance sheet and a settled sector. These banks compete hardest on cost for exactly that profile, and an incumbent relationship bank already carrying the accounts will often hold the best-priced facility. They fit less well where leverage runs ahead of a bank's appetite, the sector or structure is unusual, or the timetable is tight enough that a centralised, model-led credit process becomes the binding constraint — the point at which the challenger banks and private-credit funds become the relevant comparison.
How they differ from one another
All five lend across the same core of senior and working-capital facilities, but their reach differs. HSBC UK is the most international, suited to borrowers with cross-border trade or overseas operations. Barclays carries the deepest structured and acquisition-finance bench of the five, more comfortable with leveraged and event-driven deals. Lloyds Bank has the broadest UK relationship footprint and the widest regional and sector coverage in the domestic mid-market. NatWest matches that domestic breadth with a stated mid-market focus and the widest product spread of the five, running from relationship term loans and RCFs through ABL to leveraged and acquisition finance. Santander UK sits as the more focused challenger among the incumbents, with a defined mid-market proposition. The practical differences a borrower feels are sector appetite, regional coverage and how much structuring each will do in-house.
