April 2026 - UK Lending Market

UK debenture registrations rose 14% year on year in April 2026 to almost 13,500, but the growth was narrow and, on a closer reading, largely a buy-to-let story. The two cohorts behind it, High Street banks (+29%) and property specialists (+18%), both reflect a market-wide surge in limited-company buy-to-let lending, while most SME and commercial lending fell as the Iran war weighed on business confidence.

Almost all of the year-on-year growth came from two cohorts. UK property specialists rose 18% to 7,378, and High Street banks rose 29% to 3,097. The High Street rise was concentrated in Lloyds, which more than doubled at +105% in the month and accounted for the bulk of the cohort's increase, far ahead of the other major banks. That concentration is the tell: Lloyds' figures capture a large share of the group's buy-to-let lending, so its lift, like the property specialist surge, was driven primarily by landlords incorporating portfolios and refinancing maturing deals rather than genuinely new commercial credit.

This buy-to-let activity is market-wide and structural. Record numbers of landlords have been moving portfolios into limited companies for tax reasons - a shift the Autumn 2025 Budget reinforced by raising property income tax on individual landlords from April 2027 while leaving companies unaffected. Falling mortgage rates and maturing fixed-rate deals add refinancing volume. Much of this registers as new debentures without being new lending: incorporating an existing property portfolio typically generates a fresh charge even when no additional borrowing occurs.

Away from buy-to-let, demand was soft. In April 2026 most UK SME working-capital and specialist lending fell: asset finance (-18%), R&D finance (-71%) and government-supported lending (-17%), the investment-led borrowing that firms defer when the outlook clouds over. The backdrop was the Iran war, which began in late February, pushed oil back above $100 and lifted UK inflation to 3.3%, prompting the Bank of England to hold rates rather than cut and driving business confidence to its weakest reading since 2022.

The read for April 2026 is that the headline is a buy-to-let incorporation and refinancing story, much of it re-registration of existing stock rather than new lending, while underlying commercial and SME demand stayed subdued under the weight of the Iran war and a held base rate. Year to date the grand total is up 5%, with High Street up 32% on the same buy-to-let effect, while Other banks are down 30%.
