What the IMLA Q1 2026 data shows
The Intermediary Mortgage Lenders Association (IMLA) published its Q1 2026 market data on 27 May 2026. The headline figure: average broker caseloads rose from 89 in Q4 2025 to 96 in Q1 2026 — the highest Q1 reading since the Stamp Duty deadline rush that pushed volumes to exceptional levels in prior years. The broker confidence index stands at 82, a high reading that reflects broadly favourable market conditions rather than anxiety about volumes.
For context, IMLA also reported BoE gross lending of £68bn in Q1 2026, down from £78bn in Q4 2025. That apparent decline is not a demand story — it reflects institutional processing lag as lender capacity catches up with the elevated Q4 volumes rather than any pullback in borrower activity. The demand side remains strong; the Q1 caseload figures make that clear.

Why volumes are elevated: the Q1 pull-forward
The sharp rise in caseloads from Q4 to Q1 is partly explained by a pull-forward of activity driven by two factors. First, the ongoing conflict in Iran introduced geopolitical uncertainty that prompted some borrowers to move earlier than planned — locking in rates and completing purchases before any further market disruption. Second, swap rate volatility in early 2026 created urgency: borrowers who might have waited until spring were motivated to act while fixed rates remained at levels that looked attractive relative to the uncertainty ahead.
The result is a market where brokers are managing significantly more cases simultaneously than they were a year ago. For a straightforward PAYE borrower with a single income, a standard property, and a clear credit file, a busy broker is a minor inconvenience at most. The case progresses through standard underwriting channels without complexity.
For a contractor, the calculation is different.
The specific risk contractors face in a high-volume market
Contractors with non-standard income structures — billing through a limited company, paid by day rate, with income that does not appear on a payslip — require more from their broker than a standard case. The broker needs to know which lenders will accept day-rate income, how to present that income correctly, which documentation is required and in what format, and how to manage the underwriting conversation if a lender's automated system flags the application for manual review.
When broker caseloads are at record levels, the risk for contractors is not that a specialist broker will be slow — it is that a generalist broker, managing 96 active cases and prioritising the ones that move most smoothly through standard underwriting, may deprioritise a contractor case that requires more bespoke handling. Or worse, may submit it to a lender that does not accommodate day-rate income correctly, generating a decline that then sits on the client's credit file and complicates the next application.
A declined mortgage application is not a neutral event. It is recorded on your credit file and visible to subsequent lenders. A contractor declined by the wrong lender, or assessed on salary rather than day rate, may find their next application treated with additional scrutiny even where the specialist lender would have approved them comfortably on the correct income basis.
What a specialist contractor mortgage broker does differently
Specialist contractor mortgage brokers differ from generalist brokers in three practical ways that matter when the market is busy.
First, they know which lenders accept day-rate contractors and process them fastest. Not all lenders that technically accept contractor applications prioritise them in their underwriting queue. A specialist broker with regular volume through specific lenders has the relationship context to know where a contractor application will move efficiently and where it will stall.
Second, they apply the day-rate annualisation methodology from the outset. There is no exploratory step of submitting to a standard income assessment and seeing what comes back. The income is packaged correctly before it goes near a lender, which reduces the risk of a query, a downward revision, or a decline that could have been avoided with different presentation.
Third, in a high-volume market, specialist brokers are not stretched in the same way on contractor cases. A contractor case is a standard case for them. The complexity that might cause a generalist to deprioritise or mishandle an application is the everyday work of a specialist.
The broker confidence index and what it signals for contractors
An IMLA broker confidence index of 82 is a high reading. It reflects a market where brokers believe conditions are favourable and business will continue to flow. For contractors, this is a double-edged signal: it means market conditions are genuinely good right now, but it also means competition for broker attention is high. Getting in front of the right specialist broker — one with capacity and the right lender relationships for contractor income — is part of the practical work of securing a good outcome in the current environment.
Contractors who approach a specialist broker early, provide their documentation in order, and move quickly through the review process are well positioned. Those who delay, or who approach a generalist broker on the assumption that a busy market means any broker will do, are taking unnecessary risk in a market that rewards preparation.
