Yes, seafarers borrow for UK mortgages across multiple lenders in the market. There is no single figure and no fixed multiple. What you can borrow comes down to the income a lender will assess and an affordability test, and for seafarers the assessed income is where the real difference lies. Get that read correctly and your borrowing reflects what you genuinely earn.
Situations we see regularly
- Income paid in a foreign currency.
- A nil or low tax bill from the Seafarers Earnings Deduction.
- Rotational contracts with long spells at sea.
- A deposit saved while working abroad.
What decides how much a seafarer can borrow?
Two things: the income a lender is willing to assess, and how that income fares against the lender's affordability test. The test weighs your committed outgoings, dependants and any existing credit against the assessed income. No lender fixes a figure in advance, but the assessed income is the lever that moves your number most, and for seafarers it is also the part most often read wrongly.
How does foreign currency change the figure?
A lender applies a reduction to your converted foreign currency pay, and the size of that reduction varies between lenders, so the lender you choose changes your borrowing more than the rate does. How lenders convert and assess foreign currency income is covered in detail on our seafarer foreign currency income page.

Start the 60-Second CheckHow does the Seafarers Earnings Deduction affect borrowing?
The Seafarers Earnings Deduction (SED) lowers your UK tax, not your earnings. An automated check can read the low tax figure as a low income and shrink what it will lend. A lender that understands seafarers works from your gross contractual pay instead, so the deduction does not have to cost you borrowing. Our Seafarers Earnings Deduction page covers the evidence a lender will want.
What a seafarer can borrow is set by the income a lender will assess, not by the headline figure on a payslip.
What else affects the amount?
Your deposit and the resulting loan to value, the property itself, your other commitments and your residency all play a part. UK-resident seafarers can often reach standard borrowing levels, subject to criteria, while non-resident cases tend to face a shorter list of lenders and a larger deposit. You must be on UK soil to receive advice, so we confirm your circumstances properly before pointing you anywhere.
How do I find my number?
The honest answer is that it depends on the lender, and the right lender for your income is the one whose assessment treats your pay fairly. Mortgage One has access to plans from the whole of market and gives professional advice on where your case fits, so the figure you are quoted reflects how you are genuinely paid.
Stop guessing at the number. Let an adviser work it out from your real income.
Check Your OptionsFrequently asked questions
Is there a fixed income multiple for seafarers?
No. There is no single multiple that applies to everyone. A lender works from your assessed income and an affordability test that weighs your outgoings and commitments, so the figure is built around your circumstances rather than a flat rule.
Does foreign currency pay reduce how much I can borrow?
It can. A lender converts non-sterling pay to sterling and applies a reduction to allow for the rate moving, then works from that figure. The size of the reduction varies between lenders, so the lender you choose affects the amount more than the rate does.
Does the Seafarers Earnings Deduction lower what I can borrow?
Not with the right lender. The deduction lowers your tax, not your earnings, and a lender that understands seafarers works from your gross contractual pay rather than the low tax figure on your return.
