The full answer
What actually decides it.
Yes, and for most foundation dentists it is more straightforward than a first refusal suggests. During your foundation year you are employed. If that contract is permanent you are an employed applicant like any other, and finding a lender is not the hard part.
The numbers make the shape of the problem clear. Foundation pay is set nationally rather than practice by practice: from 1 April 2026 the training payment is £3,658 a month, which is £43,896 across the year, and it is the same wherever you are placed. At a common four and a half times income – and the multiple varies by lender – that supports somewhere around £197,500. Within a year or so of finishing you could reasonably be earning half as much again. You are being assessed at the bottom of a curve that everyone in the profession knows you are about to climb.
The complication is not where you are. It is where you are going. Most foundation dentists move into an associate post and go self-employed within a year or two of qualifying, and that transition is what a lender is really pricing when it looks at you. A lender that sees a short contract followed by self-employment sees two kinds of uncertainty stacked on top of each other. A lender that understands the dental career path sees the ordinary route into a profession, on which income usually rises.
So the pool of lenders willing to lend to a foundation dentist who is heading for self-employment is smaller than the pool willing to lend to a foundation dentist generally. Smaller is not closed. It does mean the choice of lender does more work here than anything else in the application, which is worth knowing before your credit file has been searched.
What decides it in practice is how completely your income is evidenced. Payslips on their own show what you earn today. Your practice contract shows the volume of NHS or private treatment you are committed to across a year. Where you have already moved, or are about to, an accountant’s projection shows what the next twelve months look like. Together those read as a career with a direction. Separately they read as a short contract.
Which makes the useful question not whether you can borrow, but how much, and which lender will let you – and that is worth establishing before you start looking at houses rather than after an offer has been accepted.
Where lenders differ
- One group reads a foundation contract as short-term work and treats the move into self-employment as income becoming less stable. That combination is often enough on its own for a decline, and it is where most first refusals come from.
- A second group treats foundation-to-associate as the normal progression it is, and underwrites on the basis that income is more likely to rise than fall. This is the smaller group, and it is the one worth approaching.
- The flexibility usually carries a small price. Lenders that will work around the shape of a dental career tend to sit slightly above the sharpest high-street rates, so the trade is a little on rate against an outcome.
