For too long, the UK mortgage system has operated on a simple, often frustrating, principle: if your income doesn’t fit neatly into a “basic salary” box, it’s a risk.
This has created a major hurdle for a huge number of financially secure individuals who rely on complex or multiple income streams. Whether you are a top-performing salesperson with significant commission, a self-employed business owner, a public sector worker with unsocial hours pay, or a contractor paid a day rate, your true earning power has been routinely undervalued by generic lending formulas.
The good news? The rigid criteria that automatically discounted your consistent, hard-earned income are being challenged. A combination of regulatory guidance and intensified competition is pushing the mortgage market towards a far more common-sense approach, finally putting the focus on stability over simplicity.
The Shift from ‘Computer Says No’ to Context
The core issue has always been technology meeting reality. Post-2008 lending rules enforced a strict, formula-driven approach to affordability. If your payslip showed “Overtime,” “Bonus,” or “Commission,” the system often applied an immediate, arbitrary discount—sometimes as high as 50%—or ignored it entirely.
The Financial Conduct Authority (FCA) has been reviewing these rules, recognising that this rigid framework is locking out creditworthy borrowers. The focus is shifting: the market is being encouraged to look at the “broader picture” of a borrower’s financial life, moving away from purely automated checks towards manual underwriting that uses human judgement.
What this means for those with complex income:
1. Maximising Variable Earnings
For employed people, variable pay often makes up a substantial and reliable part of their income.
- Commission and Bonuses: In the past, annual bonuses were treated with suspicion. Now, many lenders are prepared to accept 100% of regular bonus or commission income, provided you can show a consistent track record (typically 3 to 12 months, depending on the lender).
- Sales professionals, finance workers, and corporate staff who rely on incentive schemes often saw annual or quarterly bonuses treated with extreme caution. Now, many lenders will calculate an average over the last 3, 6, or 12 months, potentially using that full figure to boost affordability.
- Overtime and Shift Pay: Whether you’re a senior engineer on call or a healthcare professional covering weekend shifts, if that income is consistent, a growing number of lenders will factor in the full amount, rather than a percentage.
- Frontline Professionals (NHS, Police, Fire, Rail): Your unsocial hours, weekend shift pay, and consistent overtime are no longer automatically discounted. Lenders are beginning to acknowledge the secure nature of these sectors and are prepared to accept up to 100% of regular, documented variable income. Counting the full amount of these consistent payments, instead of just 50%, can significantly increase your overall borrowing potential.
This difference is significant. Counting 100% of just a month in regular overtime can increase your total accepted annual income by , which, on a 5x income multiple, could boost your borrowing power by a critical .
2. Self-Employed and Directors Gain Flexibility
The shift towards context is particularly beneficial for the self-employed, company directors, and contractors.
- Company Directors: Historically, directors often needed two to three years of accounts and could only use a combination of salary and dividends. Today, we are seeing increasing flexibility, with some lenders prepared to consider applicants with just one year’s accounts or who will look at retained profits within the business as evidence of affordability.
- Contractors: Day-rate contractors, from IT to finance, no longer need to rely solely on two years of accounts. Many specialist lenders understand the stability of a strong contract book and will use the day rate to calculate an annualised income, offering higher multiples than a high-street bank might.
The Challenge: Finding the Right Lender
While the overall environment is more favourable, the market is highly fragmented. Mainstream high-street banks often struggle to implement these nuanced rules, reverting to their cautious, simple formulas. The lender who accepts 100% of your overtime may only lend 4.5x income, while another taking 75% might stretch to 5.5x income overall.
This is the point where the value of specialist expertise is clear. Navigating this new landscape means identifying the specific banks and building societies whose internal, manually underwritten criteria align perfectly with your complex pay structure.
