Remortgaging as a single income household: What actually changes when you're the only name on the mortgage
This is for any woman remortgaging on her own income, whether that's because a relationship has ended, her circumstances have shifted, or she has simply decided to hold the mortgage alone. It covers how lenders actually assess a single income, what it takes to remove someone else's name from the mortgage, and what the process is likely to cost.
Why more women are remortgaging on their own
More women are taking on a mortgage by themselves than at any point in recent years. According to Mojo Mortgages' own analysis of its mortgage applications, the proportion of sole female applicants rose from 14% in 2020 to 17% in 2025, and women now make up 47% of all applicants, up from 36% five years earlier (Mojo Mortgages, 2026). Some are remortgaging after a relationship ends, some are the higher earner wanting the mortgage to reflect that, and some are simply reassessing a property bought jointly years ago. Whatever the reason, a lender is about to look at your income on its own for the first time.
How much you can actually borrow on your own
Most UK lenders offer a single applicant four to four and a half times their annual income as a starting point, with enhanced multiples of five to five and a half times available from lenders including Halifax, NatWest and Skipton once your income clears roughly £75,000 (Fox Davidson, 2026). A handful of private banks go higher for very high earners, but that is the exception rather than something to plan around.
There is a regulatory ceiling behind these figures too. The Bank of England's loan to income flow limit restricts lending above four and a half times income to no more than 15% of a lender's new mortgages each year, though the Prudential Regulation Authority has allowed individual lenders to flex that temporarily until the end of June 2026, provided the market average still holds at 15% (Bank of England, 2025). A five or five and a half times multiple is therefore never guaranteed, even if your income clears the threshold on paper.
Say your salary is £70,000 and you are remortgaging alone on a standard 4.5 times multiple. That puts your borrowing power at roughly £315,000 before affordability checks even begin. Every lender must then stress test whether you could still afford the mortgage if rates rose, under the Financial Conduct Authority's rules (FCA, MCOB 11.6.18R), and with the average two year fixed rate at 5.77% in mid-September 2026 (Moneyfacts, via HomeOwners Alliance), that stress test is usually what narrows the headline figure down to a real one.
Taking someone off the mortgage: what a transfer of equity actually involves
If you want a former partner's name removed from an existing mortgage, that step is called a transfer of equity, and it sits apart from the lending decision itself. Your lender must formally agree to it, since they are releasing one borrower from the debt, and will only do so once satisfied you can afford the mortgage alone.
Solicitor and conveyancing fees typically run from around £399 up to £1,000 or more depending on complexity, plus a Land Registry fee and possibly a lender administration fee (SAM Conveyancing, 2026). Transfers between spouses, and transfers made under a formal divorce agreement, are exempt from Stamp Duty Land Tax. Unmarried couples do not get that automatic exemption, so it is worth asking a solicitor early whether any duty applies to your situation.
If your income alone doesn't stretch as far as you hoped
You have more room to negotiate than most people assume. Extending your mortgage term reduces your monthly payment and can bring a tight affordability figure back into reach, though you pay more interest over the life of the loan. Some lenders will also count a second income stream, such as regular overtime, a consistent bonus or rental income, if you can evidence it over several months.
It is worth speaking to a broker with access to lenders offering enhanced multiples for your income band, rather than assuming the first figure you are given is the only one available. A good broker will also tell you honestly when the real answer is a guarantor, a longer timeline or a different property, rather than simply a different lender.
From Lucy, co-founder of Welleness
I became the higher earner in my own household a few years into our marriage, and I remember how strange it felt the first time a lender talked to me, rather than around me, about what we could borrow.
I have since spoken to so many women doing some version of this alone, whether after a divorce, after deciding a property should sit in their own name, or simply because they have become the person the numbers now rest on. Almost all of them assume they will be offered less than they actually are, because they are still measuring their own borrowing power against a joint figure that no longer applies.
A lender assessing you on your own is not a smaller version of being assessed as a couple. It is a different calculation entirely, done properly, on your own terms. Go into it with your real numbers, not your old ones, and ask every question you would ask if it were somebody else's money on the table.
What you can do now
Ask your current lender or a broker for a same-day affordability estimate based on your income alone, before you start comparing rates.
If a transfer of equity is part of your plan, get fixed-fee quotes from two or three conveyancing solicitors this week, since prices vary widely for the same piece of work.
If your income includes overtime, a bonus or rental income, start gathering three to six months of evidence for it now, since lenders want to see a pattern, not one month's figure.
Frequently asked questions
Can I remortgage on my own if the mortgage is currently in joint names?
Yes, though your lender must formally agree, usually through a transfer of equity, and will reassess the whole application on your income and credit history alone.
How much can I borrow on a single income in the UK?
Most lenders offer four to four and a half times your annual income, with some extending to five or five and a half times once you earn above roughly £75,000, subject to affordability checks.
Does it cost anything to remove someone from a mortgage?
Yes. Expect solicitor and conveyancing fees of roughly £399 to £1,000 or more, plus a Land Registry fee, though transfers between spouses are exempt from Stamp Duty Land Tax.
What if I can't borrow enough on my own to keep the house?
You still have options, including extending the term, evidencing extra income such as rental income, or speaking to a broker about enhanced multiples, before assuming you need to sell.
Here is what one Welleness member said after speaking to one of our advisers.
"Speaking to Elle is like an icebreaker, there's nothing to lose by speaking to her candidly. She responds like an IFA would. It's almost like a practice run. And she's not saying I'm stupid, she's saying it's really good that you're looking into these things. It would make you feel more comfortable and more confident about speaking to an IFA."
