Inside IR35 Mortgages – Expert Mortgage Solutions for Contractors Paid via Umbrella Companies

If you’re a contractor working inside IR35, you’re likely paid through an umbrella company or PAYE-style setup, making your income look like that of a traditional employee. But when it comes to getting a mortgage, many lenders still don’t know how to assess your real earning potential.

At Mortgage Knight, we specialise in helping inside IR35 contractors secure mortgages based on your full contract income, not just basic payslips. Whether you’re buying, remortgaging or investing, we make your income work harder for you.

Who We Help

We support:

  • Inside IR35 contractors working via umbrella companies
  • Fixed-term PAYE contractors with rolling contracts
  • Healthcare, IT, oil & gas, engineering and education professionals
  • Contractors with non-standard payslips or mixed income
  • First-time buyers, home movers and remortgagers
  • Umbrella-paid professionals struggling with high street lenders

The Problem With Inside IR35 Mortgages

Many traditional lenders:

  • Only assess your basic PAYE income (not bonuses or allowances)
  • Ignore your gross contract value
  • Demand years of accounts or payslips
  • Don’t understand umbrella structures or variable income

The result? You may be offered less than you’re actually able to afford.

How Mortgage Knight Solves This?

We work with lenders who:

  • Accept gross contract income for affordability
  • Use contract value or day rate x 46–48 weeks
  • Understand umbrella pay structures
  • Offer competitive rates for contractors
  • Accept just your current contract and a few payslips

We structure your case properly, so you can borrow more with less hassle.

Example: Contract-Based Affordability

Daily rate: £400
Assumed annual income: £400 × 5 days × 46 weeks = £92,000

Instead of only assessing a £55,000 umbrella payslip, lenders using this method would base your mortgage on £92,000—a huge difference in affordability.

Frequently Asked Questions

A: Yes. We work with lenders who understand umbrella pay and can assess you based on gross contract value, not just basic PAYE.

A: Usually:

  • Your current contract
  • 3–6 months of payslips
  • Bank statements
  • Proof of ID and deposit

We’ll guide you through exactly what’s required.

A: Yes, especially if you have previous experience in the same role or industry. Some lenders only require 3 months of work history.


A: That’s common with umbrella contractors. We’ll either average recent payslips or use your contract value, depending on what works best.

A: Not necessarily. With the right lender, rates can be just as competitive as standard mortgages.
