If you’re paid through an umbrella company, there’s a number on your payslip and a different number on your contract.
The gap is not small.
Which of the two a lender uses is one of the more consequential decisions made about your application — and it’s made without your input.
The rate agreed with your agency is what the umbrella receives, not your salary. Out of it come employer National Insurance, the Apprenticeship Levy, holiday pay accrual, any employer pension contribution and the umbrella’s own margin.
The difference is commonly ten to fifteen per cent, and sometimes more.
At five and a half times income, a fifteen per cent reduction in your assessed figure is a fifteen per cent reduction in borrowing.
What Lenders Do in 2026
Some use the gross contract rate
They take the rate on the assignment schedule and annualise it in the usual way, regardless of IR35 status. For umbrella contractors this is by some distance the most favourable treatment.
Some use the payslip
They work from the gross figure shown after employment costs have come out, which produces a materially lower assessed income.
Some sit in between
Working from the contract rate but applying a deduction, or requiring both documents and reconciling them.
April 2026 changed the backdrop
New PAYE rules for umbrella supply chains took effect for payments made on or after 6 April 2026, making agencies or end clients jointly and severally liable where an umbrella fails to operate payroll correctly. Separately, the small-company thresholds for off-payroll purposes increased.
Lenders don’t assess IR35 directly
They care how much you earn and how reliably, not how you’re taxed. IR35 matters because it determines what documentation exists.
Case Studies
Case Study 1: Karim – £600 a Day, Slough
Karim’s umbrella payslips showed gross pay well below his contract rate once employment costs had been deducted.
A lender working from his assignment schedule rather than his payslip assessed the same contract considerably higher.
Case Study 2: Sophie – Umbrella Switch, Norwich
Sophie’s agency changed its approved umbrella list mid-assignment, resetting her employment history with a new employer.
A lender assessing from payslips read three months’ service as a recent job change. Evidence that the underlying contract predated the switch resolved it.
Case Study 3: Dan – Moved Back to a Limited Company, Hull
Dan left an umbrella arrangement for his own company six months before applying.
He had payslips for the earlier period and thin company accounts for the later one. Identifying the issue early gave time to place the case appropriately.
Why Outcomes Differ
- Whether the lender uses the contract rate or the payslip figure
- How long you’ve been with your current umbrella
- Whether your assignment schedule shows the gross rate
- Recent changes in payment structure
- Contract continuity and unexpired term
