Securing a mortgage when a substantial portion of your compensation is paid in Restricted Stock Units (RSUs) presents distinct challenges on the UK high street. Standard retail lending algorithms are designed for basic salaried income. As a result, standard credit scoring models often exclude equity vesting entirely, treat shares as volatile one-off bonuses, or decline applications through standard channels.
Specialist manual underwriting desks, premier banking divisions, and private banks take a completely different view. When packaged and evidenced accurately, your equity awards can be factored directly into affordability calculations, significantly expanding your borrowing capacity.
Why Standard Mortgage Lenders Struggle with RSUs
Quick Answer: Do UK Mortgage Lenders Accept RSU Income?
Yes, but acceptance depends on whether the application is processed through automated retail channels or manual specialist underwriting.
While several mainstream high-street lenders explicitly exclude RSUs from standard online assessments, specialist lending desks, select high-street private arms, and bespoke institutions accept between 50% and 100% of historical vested RSU income.
Lenders typically require:
- A consistent 12-to-24-month track record of vesting.
- A forward vesting schedule demonstrating ongoing releases over the next 12 to 36 months.
- Employment with a publicly traded company on a recognised global exchange.
How Specialist Underwriters Assess RSU Affordability
Equity compensation is standard for software engineers, senior leaders, and technical specialists at firms like Amazon, Google, Meta, Microsoft, and Apple. However, standard branch and aggregator application systems often fall short due to specific policy constraints:
- Explicit Exclusions in Retail Criteria: Major lenders often list RSUs and stock options under non-acceptable income for standard retail mortgage products, requiring bespoke referral routes.
- Vested vs Unvested Confusion: Standard automated forms cannot distinguish between future unvested grant projections and past taxable vesting events. Lenders derive borrowing power from historical vested income, using future vesting purely to satisfy income continuity rules.
- Foreign Currency Deductions: If your stock is denominated in US Dollars (USD), standard criteria often apply a mandatory foreign currency haircut (typically between 10% and 25%) to account for foreign exchange volatility before applying income multiples.
- Brokerage Platform Evidence: Automated systems look for basic monthly net pay on standard bank statements, frequently misinterpreting distribution statements from equity platforms like Morgan Stanley at Work, E*TRADE, Charles Schwab, or Shareworks.
Borrowing Comparison: Base Salary vs Total Remuneration
Specialist underwriters assess RSU compensation by analysing total remuneration rather than relying solely on base salary. Underwriting teams examine your application against four central components:
1. The Historical Vesting Track Record
Lenders typically assess a 2-year average of your vested RSU income, evidenced via P60s, itemised payslips, and brokerage settlement reports. If the most recent 12-month period is lower due to market movements, underwriters will usually base calculations on the lower figure to maintain sustainable affordability.
2. Forward Vesting Pipeline (Income Sustainability)
Underwriters require evidence that your stock compensation will continue. A forward vesting schedule showing scheduled share releases for at least the next 12 to 36 months confirms to the lender that equity compensation is an ongoing part of your remuneration rather than a historical one-off event.
3. Share Price Averaging and Haircuts
Because share prices fluctuate, specialist lenders typically take between 50% and 100% of the historical annual average. High-net-worth and premier desks assessing established FTSE 100 or NASDAQ-listed firms can recognise up to 100% of the 2-year average when strong employer performance is documented.
4. Treatment of Sold vs Retained Stock
Underwriters verify the taxable event at the point of vesting via your UK payslip (confirming PAYE income tax and National Insurance deductions). Whether you immediately liquidate the shares into cash or retain them in your brokerage account, specialist desks recognise the vested value once tax obligations have been satisfied.

How Cleerly Helps You Secure an RSU Mortgage
Specialist underwriters assess eligibility using the following core criteria:
- Employer Status: The issuing company must generally be listed on a recognised global stock exchange (e.g., LSE, NASDAQ, NYSE). Pre-IPO or private equity shares are typically excluded until a public market exists.
- Vesting Schedule: A documented forward vesting plan spanning at least 12 to 24 months.
- Track Record: A minimum 12-to-24-month continuous history of vesting under the current or previous comparable employment scheme.
- Taxation Records: Clear evidence of tax and National Insurance paid at the point of vesting via PAYE payslip entries.
Assembling the correct documentation pack in advance prevents underwriting delays:
- Employment Contract & Grant Agreements: Formal documentation detailing your base salary, bonus structure, and initial RSU grant terms.
- Forward Vesting Schedule: An official report from your equity portal (e.g., Shareworks, Morgan Stanley, Charles Schwab) detailing future vesting dates and unit counts.
- Brokerage Statements: 12 to 24 months of trade confirmations, vesting slips, and account summaries.
- Payslips & P60s: Latest 3 to 6 months of itemised payslips clearly displaying RSU taxable events, alongside your last 2 years of P60s.
- Bank Statements: Latest 3 months of primary personal bank statements showing net salary credits and day-to-day living expenditure.
