Mortgages for locum doctors are available, but lenders look at locum income differently from a standard NHS salary. That’s the part that trips people up. It isn’t that you can’t borrow. It’s that you have to show your income in a way the lender understands.
This guide walks through it in the order you’ll actually face it. Can you qualify? How will your income be assessed? What might you borrow? What paperwork do you need? And what can make things harder? One quick note first: lender criteria change often, so where I mention figures, treat them as examples, not promises.
How Do Mortgages for Locum Doctors Work?
Yes, in many cases. Being a locum doesn’t automatically block a mortgage application. What it does is change how the lender reads your finances.
Plenty of high street banks like simple, regular income. A monthly payslip, the same employer, the same amount. Locum work doesn’t always look like that. Your hours move around, your rate might differ between shifts, and you could be working for several trusts or agencies at once. Some lenders are comfortable with that. Others aren’t. And each one decides case by case, after checking affordability.
So if one bank turns you down, it doesn’t mean every lender will. It may just mean that lender’s rules don’t suit how you earn.
Why Locum Income Can Be Treated Differently
It really comes down to one question in the lender’s head: how reliable is this income, and will it keep coming in?
Notice it isn’t about your profession. Doctors are generally seen as low-risk borrowers. It’s the shape of the income. Variable earnings, short contracts and gaps between assignments make a lender cautious. They’d rather see a pattern. You’ll also hear people say all locums are treated as self-employed. That’s not always true. A locum paid through payroll, an umbrella company or their own limited company can all be assessed differently.
How Long Do You Need to Be a Locum Doctor Before Applying?
It depends heavily on the lender. Some will consider a fairly short locum history. Others want a longer record, such as two years of tax returns or accounts.
One UK broker, Jamie Thompson Mortgages, says on a page last updated in February 2026 that some lenders will look at as little as three months of locum work, while others want two full years. That’s one broker’s view, not a rule across the market. But it shows how wide the range can be. In practice, a longer history usually opens up more lenders, which is why the options for mortgages for locum doctors grow the longer you’ve been working. More choice often means better chances of a competitive rate, though your deposit can matter just as much as your track record.
Can You Apply After Only Three Months of Locum Work?
It can happen, yes. A few lenders will look at someone with a short track record, usually going off recent invoices or work that’s already been contracted. But three months isn’t a promise of anything, and it’s not some fixed rule either. They’ll still go through your credit file, see what you spend each month, and try to judge whether the work looks like it’ll keep coming. And if you’ve only just started out, picking the right lender counts for a lot more than it does for a person with years of accounts behind them.
How Do Lenders Assess Locum Doctor Income?
There’s no single formula. Different lenders use different methods, and the same doctor can look stronger or weaker depending on which one they approach. Here are the main ways income gets looked at.
Recent Invoices or Contracted Income
Some lenders focus on your most recent earnings. They might take a few months of invoices, work out what that adds up to over a year, and base your borrowing on it. This can suit you if your income has gone up lately. It also means a quiet few months could count against you.
Tax Returns and Net Profit
Other lenders prefer a longer view. If you’re a sole trader, they may ask for SA302 tax calculations and Tax Year Overviews from HMRC, usually covering a couple of years. They’ll look at your net profit, which is what’s left after allowable expenses. A smoother, proven record can help here. But if your income recently jumped, a two-year average might not show it.
HMRC publishes a list of mortgage providers and lenders who accept an SA302 tax calculation or Tax Year Overview, which is worth a look if you’re self-employed.
Salary and Dividends
If you work through your own limited company, some lenders look at the salary and dividends you pay yourself. Others look at company accounts or retained profit. It’s not the same thing as a payslip, so check how your chosen lender treats it before you apply.
PAYE, Umbrella or Agency Income
If you’re paid through an agency, umbrella company or PAYE, you’ll often provide payslips and perhaps a P60. Some lenders are happy with a few months of payslips. Others want longer. Again, what’s accepted depends on the lender, not on a universal rule.
How Much Can a Locum Doctor Borrow?
This is the question everyone asks, and sadly the honest answer is “it depends.” Your borrowing comes down to your assessable income, your monthly spending, your deposit, your credit profile, the length of the mortgage and the lender’s own affordability model.
With mortgages for locum doctors, you’ll often see income multiples quoted, such as 4.5 times income, sometimes more. Treat those as rough examples, not a promise. Lenders vary, and the multiple only matters once they’ve decided which income figure to use.
Here’s a made-up example to show why. Say your invoices come to £6,000 a month, and your two-year average net profit is £62,000. A lender looking at recent invoices might annualise that to £72,000. At a hypothetical 4.5 times, that suggests £324,000. Another lender using the two-year profit at, say, five times would land on £310,000. Different method, different answer, same person. And neither number is a quote, because every lender then runs its own affordability checks.
Borrowing limits also shape where you can realistically buy. If you’re curious how that plays out in practice, our piece on how affordability is driving buyer migration to Kirkcaldy shows how budgets steer people towards certain areas.
What Deposit Do You Need for a Locum Doctor Mortgage?
On mortgages for locum doctors, some lenders will consider applications with a 5% deposit, which means borrowing up to 95% of the property’s value. That’s called loan-to-value, or LTV. But it isn’t automatic, and the lender’s other rules still apply.
A bigger deposit usually helps. It can open up lower interest rates and sometimes lets you borrow more. The jump in rates between, say, 95% and 90% LTV can be noticeable, so it’s worth running the numbers for both.
Where the money comes from matters too. Savings and money saved from income are usually fine. Gifted deposits, often from close family, are commonly accepted, but you’ll normally need a gifted deposit letter. Some lenders are stricter about this than others. Keep records of where the money has been, because the lender will ask.
What Documents Do Locum Doctors Need?
If you’re applying for a mortgage as a locum doctor, expect a longer paperwork list than a salaried colleague. What you’ll need depends on how you’re paid, but these are common:
- Recent invoices or payslips
- Personal bank statements
- Business bank statements, if you’re paid into a business account
- SA302s and Tax Year Overviews, where you’re self-employed
- Company accounts, if you run a limited company
- Your locum contract or engagement paperwork
- Proof of deposit
- ID and proof of address
- Proof of right to live in the UK, where relevant
- Details of existing debts and a copy of your credit file
Why Lenders Ask for Different Documents
Because they want to see your income the way they measure it. A lender that looks at recent invoices needs invoices. One that uses tax returns needs those. That’s why getting documents ready before you talk to anyone saves time. If a broker or lender asks for something odd, ask why. It’s usually linked to how they’ll calculate your income.
Does Your Locum Contract Type Affect Your Mortgage?
It can, yes. When you’re hunting for a mortgage for doctors on a locum contract, the first thing any lender asks is how the money actually reaches you.
If an agency pays you through PAYE, you’ll normally have payslips to show, which keeps things simple. Umbrella set-ups look much the same on paper, although a few lenders want some extra paperwork. Sole traders end up leaning on invoices, bank statements and tax returns. Directors of a limited company might be judged on their salary plus dividends, or on the company accounts instead. And with fixed-term work, the worry is usually how long it’s going to last.
No single route is automatically the best one. What counts is how the lender reads the income that each structure produces. You can have two doctors earning exactly the same, and one gets a yes while the other gets a maybe, just because one is on PAYE and the other runs a company.
Can You Combine Salaried and Locum Income?
Often, yes, depending on the lender. If you have an NHS post and do locum shifts on the side, some lenders will count your basic salary plus a portion of your extra earnings. They may look at recent locum income, annualise it, and add it on.
You’ll need to show both. Payslips for the salaried job, plus invoices or bank statements for the locum work. Lenders also differ in how much extra income they’ll count and how they treat your other debts, so shop around.
Can You Get a Mortgage as a Newly Started Locum Doctor?
Sometimes. If you’ve only recently gone locum, lenders will usually want other evidence of stability. A previous employment record in medicine can help. So can a clear contract, steady shifts booked in advance and recent invoices.
What they’re really asking is: will this keep going? A short history isn’t a dead end, but it narrows your choices. Picking a lender whose criteria suit new locums matters more here than for anyone else. Don’t assume approval just because you’ve hit a certain number of months.
What If Your Locum Income Has Recently Increased?
Say you’ve started working more shifts or your daily rate has gone up. That can help, depending on the lender. One that looks at recent invoices may be able to use your higher earnings quickly. One that averages two years of profit won’t see the rise yet.
But recent income doesn’t automatically become your accepted annual income. Lenders want it to look sustainable. If the jump comes from an unusually heavy run of shifts, they may not count all of it. Being able to explain the increase, with contracts or booked work, makes your case stronger.
Can Non-UK Locum Doctors Get a Mortgage?
It’s possible, but lenders get stricter. They usually look at your visa, your right to live in the UK, how long you’ve been here, how much time is left on your visa, your UK address history and your UK credit record.
Some lenders restrict lending to people without indefinite leave to remain. Others are more flexible, sometimes asking for a larger deposit. A strong UK credit history helps a lot. The honest advice is to check lender criteria carefully, because they change and vary widely. Don’t rely on figures you’ve seen online for “months on a visa” without confirming them.
What About Pre-Settled Status?
Pre-settled status doesn’t automatically rule you out with every lender. Some accept it, others have tighter conditions. Ask your adviser or the lender directly, and have your documents to hand.
Can First-Time Buyers Get Mortgages as Locum Doctors?
Yes. Being a first-time buyer doesn’t exclude you, and being a locum doesn’t either. Both groups are treated like anyone else: the lender checks your deposit, your income evidence and affordability.
The deposit is usually the biggest hurdle. If you’re deciding where to buy, our guide to what makes Dundee attractive for first-time buyers is a useful read. Check which government schemes are currently available before planning around them, since these change.
Are Mortgage Brokers for Locum Doctors Worth Using?
Often, yes. Mortgage brokers for locum doctors see this kind of case week in, week out, so they’ve got a decent feel for which lenders won’t flinch at patchy pay, and for how each one actually counts it. Someone who knows the market can steer you toward the few whose rules fit your situation instead of leaving you to guess. They can also read through your documents before you apply and put your earnings across clearly, which is half the battle with an underwriter.
Why bother? Because a decline from the wrong lender stays on your credit file. Don’t expect miracles, though. No broker can promise the best deal, and they don’t all work the same way. Fees are a good example. A flat amount is one way, commission from the lender is another, and plenty of brokers mix the two. Before you commit, get them to tell you how they’re paid and what that covers.
And check they’re authorised. It takes a couple of minutes on the Financial Services Register, and the FCA explains how to check a firm or individual is authorised.

Common Mistakes Locum Doctors Should Avoid
A few slip-ups come up again and again:
- Applying before checking whether the lender’s criteria fit you
- Assuming every lender calculates income the same way
- Sending incomplete documents
- Using an optimistic income figure rather than a provable one
- Forgetting about existing debts and credit cards
- Opening new credit just before applying
- Treating three months of income as a guaranteed pass
- Focusing only on the headline interest rate and ignoring fees
None of these is hard to avoid with a bit of preparation.

Final Thoughts
Mortgages for locum doctors aren’t out of reach. Being a locum doesn’t rule you out. What matters is how your income is structured, how long you’ve earned it, what evidence you can provide, your deposit and which lender’s criteria fit your situation.
Lender rules, rates and affordability checks change, so confirm current terms with an FCA-authorised mortgage adviser or lender before making any decision. Your home may be repossessed if you do not keep up repayments on your mortgage.
