Six months of statements can prove your income; your deposit still needs its own paper trail

If you've moved to the UK recently, you've probably worked out that open banking can prove your income without three years of UK credit history behind you. Fewer customers realise that your deposit gets checked separately, by a different set of rules, and that check can run longer than the mortgage application itself. Lenders and conveyancers both need to know where your deposit came from, not just that you have it.

Money from abroad, whether it's savings built up over a decade, an inheritance or the proceeds of a property sale, gets a longer look than money that's sat in a UK account for years. Here's what lenders and conveyancers want to see, and how to get the evidence together before it becomes the reason your completion date slips.

Two checks, not one

Your lender runs an affordability check; it wants to see regular income, committed spending and a pattern of financial discipline, and open banking has made that check faster for new arrivals than it has ever been.

Your lender and your conveyancer also run a separate source of funds check on the deposit; this one asks where the money came from and whether it can be traced back to something legitimate. These are not the same test. A customer can have a strong, verifiable income and still hold up completion for weeks because the deposit's origin isn't documented cleanly; solicitors and lenders are required to check this under money laundering rules, and they apply the same scrutiny to a returning UK citizen's savings from Singapore as they do to anyone else's.

Why money from abroad gets a longer look

A deposit sourced from a European country typically needs three months of statements; one from outside Europe typically needs six. If the funds sat in a foreign currency account, you'll also need evidence of the conversion: what left the account, at what rate and what landed in your UK account. So a deposit that moved through two accounts and one currency conversion takes longer to clear than one that sat still.

None of this is unique to you; it's the same standard applied to anyone moving money across a border. It just lands hardest on customers with the least slack in their moving timeline.

What counts as a clean paper trail

Lenders and conveyancers want statements showing the money accumulating, not just a snapshot of the final balance; a plain explanation of the source, whether that's salary, a property sale or a gift; and evidence of the transfer itself. If the statements aren't in English, arrange a certified translation.

Gifts and inheritances get the closest look

If a relative gifted you part of the deposit two years ago, the paperwork needed is from two years ago, not your last three months of statements; the firm checking your case wants the money's whole journey, not the most recent leg of it.

Two customers, two paper trails

Two customers can apply for the same size mortgage with the same size deposit and land on very different timelines. The difference isn't the customer; it's how many hands the money passed through before it reached a UK account.

Take a customer who sold shares she'd held for years in her home country, moved the proceeds into a single savings account there and left the balance untouched for two years before transferring the whole sum to her UK account in one go. Her lender and conveyancer could see the balance building steadily over that period, get a plain description of what the money was (share sale proceeds) and trace one transfer: one account, one currency conversion, one date. It's about as straightforward as a source of funds check gets.

Take another customer whose deposit came from selling a property abroad. The proceeds landed first in an account he held jointly with a sibling, moved to his personal account a few weeks later, then were split across two currency conversions: part changed early at one rate, the rest held back and converted months later, once the exchange rate improved. None of that is suspicious on its own; a customer manages money that way for perfectly ordinary reasons. But a conveyancer has to trace three accounts, two conversions and a sale contract, and each hop is a question that needs its own answer before completion can go ahead.

The lesson isn't to invent a cleaner history than you have; it's to know that every extra account, every currency conversion and every intermediary in the chain adds evidence a lender or conveyancer will ask for, and gathering it takes time.

If you're buying with a partner or co-applicant and only one of you is bringing deposit funds from abroad, the other applicant's UK-based finances don't offset this: the deposit's source gets checked as its own item regardless of whose income is doing the work on affordability. A broker who's seen the complicated version before can tell you which document to chase first, instead of leaving you to work it out backwards from a solicitor's question three weeks before completion.

When part of the deposit is a family gift from abroad

A gift from a parent or relative living abroad is one of the most common ways a new arrival funds part of a deposit, and it's also one of the trickiest to evidence quickly, because the paperwork trail belongs to two people, not one.

A lender wants a signed gift letter confirming the money is a genuine gift and not a loan that has to be repaid; that the giver has no stake in the property and no right to occupy it; and that the sum it describes matches exactly what arrived. That letter is usually straightforward to produce; the harder part is showing where the giver's own money came from.

Because the gift itself has to be traced, the giver's own bank statements, showing the funds accumulating in their account before the transfer, sit alongside your own evidence. If a parent sold a property to help fund your deposit, a lender wants their sale documents as well as yours; if the gift came from savings built up over years, it wants the same pattern of statements from them that it would ask of you directly. None of this becomes optional because the giver lives outside the UK; the source of funds rules follow the money, not the passport.

Two customers receiving family gifts of the same size can face very different timelines depending on how organised the giver is. A relative willing to pull together two years of statements and sign a gift letter in the first week resolves this quickly; one who has to be chased for documents from a bank in a different time zone can hold a case up for weeks. Open banking lets a lender see a customer's own income and spending within minutes of connecting an account, but there's no equivalent shortcut for a gift given by a relative who isn't the applicant; that evidence still has to be gathered by hand.

Where open banking helps, and where it stops

Open banking lets a lender verify your income and spending in real time instead of chasing payslips and bank statements by hand; for a customer without UK credit history, that's the difference between a realistic mortgage and one that isn't.

However, it doesn't touch the deposit question. Open banking shows a lender what's moving through your account now; it doesn't explain where a lump sum arrived from six months before that account existed, and it was never built to. The industry fixed the fast half of this problem and left the slow half exactly as slow as it's always been — worth knowing before you rely on your income data alone to get you to completion on time.

Moxim's readiness check covers the affordability side clearly and quickly. The deposit paper trail is a separate job, and one you can start before you've even found a property.

What can you do right now?

• Start gathering deposit evidence as soon as you know you're buying, not once an offer is accepted; three to six months of statements takes time to pull together from an overseas bank.
• Keep the deposit in one identifiable account rather than moving it between accounts or currencies more than once; every extra hop is another gap your solicitor will ask you to explain.
• If a relative or friend is gifting part of the deposit, get a signed gift letter and their supporting statements now, whatever the timing of the actual transfer.
• Arrange certified translations early if your statements aren't in English; this is a common, avoidable delay near completion.
• Talk to a broker who has handled deposits from abroad before; the requirements vary by lender and a broker who knows the pattern can flag a problem months before your solicitor would.

A fast affordability check and a slow deposit check can sit in the same mortgage application, and most new arrivals only find out which one is holding things up when their solicitor asks a question they weren't ready for. Sort the paper trail early and it stops being a problem at all.

Frequently asked questions

Does my conveyancer need different evidence than my lender?

Mostly not; both are checking the same underlying thing under money laundering rules, so a clean set of statements, a plain description of the source and a certified translation where needed usually satisfies both. Where they differ is timing: a lender's underwriter typically reviews it once at application stage, while a conveyancer keeps asking questions right up to completion, so keep the same file updated rather than assuming one check closes the other off.

What if my deposit came from selling cryptocurrency?

It's treated as a source that needs extra evidence, not one that's automatically refused. A lender or conveyancer wants the exchange records showing when you bought and sold, the wallet or exchange account history and a clear conversion into a bank account before the deposit reaches you; the more the trading history looks like a single clean sale rather than years of frequent trades in and out, the faster this tends to clear.

Can I use money that's still in a foreign currency at completion?

No; a UK property purchase completes in pounds, so foreign currency funds need converting into your UK account with time to spare before exchange, not on the day itself. Building in that buffer also protects you from a currency swing between agreeing a price and paying it, a separate risk from the source of funds check but one worth planning around at the same time.

Does a large one-off gift look worse than steady savings?

Not worse, just different; a one-off gift needs a signed gift letter and the giver's own paper trail, while steady savings need a longer run of statements showing the balance building. Neither is a red flag on its own; what a lender and conveyancer are both checking is whether the story the paperwork tells matches the story you've given them, whichever kind of money it is.

How long should a source of funds check take once I've got everything together?

With a complete, well organised file, a straightforward case (one account, one country, one clear source) can clear in days; a case with multiple accounts, conversions or a gift from abroad usually takes longer regardless of how quickly you supply documents, because a conveyancer is verifying, not just collecting. Getting the evidence together before you make an offer is what saves time, not the pace of the check once it starts.
