Mortgages for GPs and Consultants: How Lenders Assess Medical Income
Doctors, GPs and NHS consultants often earn well but on income structures that don’t fit standard mortgage assessment. A GP partner’s income comes as a share of partnership profits rather than a payslip. Consultants layer NHS salary, London weighting, on-call, bank work and private practice into one package. Getting the right lender for that mix can meaningfully change what you can borrow.
Here, we walk through how lenders assess GP and consultant income, what documentation you’ll need, how private practice earnings are handled, and when it’s worth waiting for an income change to take effect before applying.

GP and consultant mortgages: at a glance
| GP partner income (rising) | Average of the last two years' profit share, typically |
| GP partner income (falling) | Most lenders use the latest, lower year |
| Basic NHS salary and guaranteed allowances | Used at 100%, contractual and guaranteed |
| Ad hoc overtime and bank work | Usually 60-75% of the annualised 3-month average, some lenders use 100% |
| Contracted overtime and on-call | Used at 100% where it's guaranteed in your contract |
| Private practice via limited company | Usually the strongest route, at least one year's tax returns |
How do lenders assess income when you’re receiving a share of partnership profits as a GP?
If you’ve been in a partnership for two years or more, the standard approach is that your tax returns declare your share of partnership profits to HMRC and you pay tax on them separately. Most GP partners have an in-house accountant, or in smaller practices an accountant that everyone in the partnership uses, which keeps things clean.
Lenders treat your income much like a self-employed person’s, based on your declared profit share.
- Two years plus: If your income is increasing over the two-year period, most lenders use the average of the last two years’ profit share. If it’s decreasing, they’ll typically use the latest year.
- Less than two years: Depends heavily on the lender. Some lenders will assess based on one year. Some, where you don’t yet have a full year, can work on a projection from an accountant.
Projections generally lean on previous PAYE salaried earnings (from your time as a salaried GP), your agreed contractual profit share as a partner, and what other partners in the practice earn, plus the overall viability of the business.
If a GP’s profit share changes year to year, how do lenders decide which figure to use?
The standard way is that if profit share is increasing, lenders use the average of the last two years. Some lenders will work solely on the latest year even if it’s higher.
If profit share is decreasing, most lenders across the board will use the latest (lower) year. Unless there’s a very strong reason why the lower year should be discounted and the previous year used, they’ll go with the more recent figure. Only a small number of niche lenders will ignore the latest year in favour of the previous.
If you’ve only recently become a GP partner, do you need a minimum number of years of accounts?
How lenders treat a changing profit share
If you’ve only recently become a GP partner, do you need a minimum number of years of accounts?
Not necessarily. It depends on the lender.
- Some lenders require it, so those options won’t be viable for you
- Some will work on a projection of expected profit share, particularly where there’s an agreed contractual amount
The size and length of the practice also matter. If it’s a well-established practice with a good amount of experience, a strong partner base and a solid track record, projections are easier to support. If it’s a newer practice you’ve just joined, it’s harder for a lender to know what your future earnings will actually look like because there’s less history to lean on.
Can lenders consider projected partnership income if you’ve just moved from salaried GP work into a partnership?
Yes, projections can be used, again depending on the size of the partnership and what can be confirmed. Usually the confirmation comes from the finance director or the managing director of the practice, alongside sign-off from the accountant confirming the profit share is viable.
Lenders can also use your previous PAYE salaried earnings to back up the projection. That helps because it’s not a substantial jump overall, it’s an increase based on being a partner rather than a completely unproven income position.
How do lenders assess someone who has a core NHS salary alongside additional NHS earnings like overtime and bank work?
How NHS overtime and on-call income is used
How do lenders assess NHS on-call income?
On-call is treated by whether it’s contractual or not.
- Contractual on-call: If you’re contracted to do a certain amount of on-call over a set period and it’s guaranteed in your contract, it can be used at 100%.
- Ad hoc on-call: Treated the same way as ad hoc overtime, averaged over the last three months, with lenders typically using 60% to 75% of the annualised figure, though some will use 100%.
The distinction comes down to what your contract actually stipulates.
How do lenders assess private practice income alongside an NHS salary?
It depends on how long you’ve been doing it and how regularly. The main options are:
Locum or bank-style regular private practice.
If you do it every week and it’s structured like locum work or bank work, you’ll usually get weekly separate payslips. That can be treated as overtime and used alongside your NHS salary.
Via your own limited company.
The standard way of using this income is on tax returns from the limited company. This is often the strongest route, because it captures earnings that have actually been drawn and declared.
Via invoices.
Some lenders will use invoices for private practice income, but this is very niche because it’s pre-tax gross figures, and reflects what you’ve invoiced rather than what you’ve actually been paid for at that point.
In general, the best option if you’re doing private practice through your own limited company is at least one year’s tax returns done on that limited company. But there are different options depending on the specific line of work, and some lenders will be more flexible than others compared to a standard sole limited company setup with less than a year’s trading.
What documents should a GP partner or consultant get together before speaking to a broker?
Documents to prepare, by income type
| Income type | What to prepare |
|---|---|
| Salaried NHS work | Last 3 months' payslips |
| Self-employed / partnership, 1 year trading | Tax return, tax calculation and tax year overview |
| Self-employed / partnership, 2+ years trading | The last two years of tax returns, tax calculations and tax year overviews |
| Self-employed / partnership, less than 1 year | Invoices for the work completed so far, to assess viability |
The starting point is having a conversation with a broker to see if you have enough income now without even needing the increase. It could be that you don’t need it at all.
If you do need the increase, how it’s assessed depends on the nature of it:
- If it’s a pay rise, when it can be used depends on when it’s going to be received. Depending on which lenders you’re looking at, it might not need to have come into effect yet.
- If it’s from planning to do more work, you’ll usually need to actually show that the work has been done before it can be used.
The safest sequence is to have the conversation before you do anything, so you know how it looks, what’s needed, and what timescale you’re working on. Then you can decide when to start the application.

Frequently Asked Questions for Heron Financial
Do doctors get higher income multiples on mortgages?
Yes, in many cases. Several UK lenders offer specialist products for medical professionals with income multiples of 5.5x or 6x, versus the 4.5x standard for most mainstream applications. These typically apply to GPs, consultants, dentists, vets and other qualified medical professionals meeting specific criteria.
Can newly qualified doctors get a mortgage?
Yes. Foundation year doctors, ST-grade trainees and newly qualified GPs are usually treated on their NHS salary in the standard way. Some medical specialist mortgage products are only available once you reach certain career milestones (for example, becoming a partner or consultant), but a standard mortgage on your salary is available from day one of qualified work.
Can locum GPs get a mortgage?
Yes. Locum GP income is typically treated as self-employed. Lenders will usually want to see at least one year’s tax return, though some will consider less with strong evidence of ongoing work. Weekly locum work via an agency can sometimes be treated more like overtime alongside a core NHS role.
Do lenders count NHS pension contributions against affordability?
Pension contributions deducted at source from your NHS salary are typically not counted as an outgoing on affordability, because they’re already excluded from the take-home income the lender assesses. Voluntary top-up contributions may be treated differently depending on the lender.
Can I use both my NHS salary and private practice income for a mortgage?
Yes. Most specialist medical lenders will consider both together, provided each source can be evidenced. NHS salary is typically counted in full, and private practice is added based on tax returns, payslips, or invoices depending on how the income is structured.
Do all lenders accept partnership projections for new GP partners?
No. Only some lenders accept projections, and even those that do usually require accountant sign-off, confirmation from the practice’s finance or managing director, and evidence that the projection is realistic based on the wider partnership. Lender choice is critical here.
Should I set up my private practice as a limited company for mortgage purposes?
Not just for mortgage purposes. There are tax and administrative reasons to structure private practice one way or another that a mortgage broker isn’t qualified to advise on. What we can say is that limited company income backed by at least one year of accounts tends to be the strongest route for mortgage assessment. Speak to a qualified accountant before making the structural decision.
