TL;DR
In short
- Changing jobs does not automatically stop you getting a mortgage, but tell your lender or mortgage adviser promptly about changes to your employment or income during the application and after an offer until completion.
- An agreement or decision in principle is provisional; a formal mortgage offer follows fuller checks and the funds are advanced at completion.
- A probation period, a new contract or a future start date can be acceptable to some lenders, but their criteria and the evidence they need differ.
- Lower pay can change the amount you can borrow because the lender reassesses affordability using income, expenditure and any gap in pay.
- Before changing jobs, check the lender’s requirements and prepare the contract, income evidence and employment history they request.
Changing jobs need not prevent you getting a mortgage. However, if your employment, pay or future income changes during a mortgage application, discuss it with your lender or mortgage adviser promptly. This remains important after a formal offer and until completion, when the mortgage funds are advanced.
Lenders assess whether the mortgage is affordable from your income and expenditure, alongside other parts of your financial situation. They may also need to consider known or likely future changes. That is why they may ask for evidence of your earnings, tax paid and employment when carrying out an affordability assessment and mortgage underwriting.
This guide explains when a job change can matter, how it may affect affordability and what you can prepare for your mortgage application.
Do I need to tell my lender about a job change?
During an active application, tell the lender directly or through your mortgage adviser about a change to your job, pay or other income that could affect affordability. This includes a known or agreed future change, even if the new role starts after completion. Check the declaration you made in the application and the conditions attached to any mortgage offer.
Accurate information matters. Deliberately giving false information can amount to mortgage fraud and may affect the application or offer. A Cifas record is not a consequence of simply changing jobs or making an innocent mistake: its members must meet the relevant National Fraud Database principles and have supporting evidence before filing.
If your mortgage has already completed, that is different from an active application. Check your mortgage terms for any notification duties and keep payments up to date. If a pay reduction means you may struggle, contact your lender early — ideally before missing a payment — and consider free support from MoneyHelper.

Changing jobs during a mortgage application
An agreement in principle (AIP), also called a decision in principle (DIP), is a provisional indication rather than a formal mortgage offer. The lender carries out fuller checks on you and the property before making an offer. A formal offer may contain lawful conditions about material changes in circumstances or information that was knowingly inaccurate or withheld; the mortgage funds are then advanced at completion.
For that reason, do not assume that terms discussed at AIP/DIP stage will remain unchanged if your employment or income changes. The lender may need you to update the application or reassess affordability, which can affect the lending decision. Discuss a planned move with the lender or your mortgage adviser and obtain confirmation before relying on the existing terms.
Can you get a mortgage when starting a new job?
Potentially, yes. There is no single UK waiting period after changing jobs. A lender will consider its own policy, the contract type, start date, income evidence, employment history, any gaps and the overall application.
A probation period within a permanent role is not the same as a role that is temporary or probation-only pending a permanent offer. Some lenders can consider applicants in a new permanent role or with a signed future offer, subject to their criteria and evidence. For example, Nationwide and Halifax publish criteria covering new jobs and probation, but consideration under those criteria is not an approval guarantee.
Tell the lender about a promotion too if it changes your employment or income details. Informing the lender and deciding how the change affects the case are separate matters. Bonus, overtime and commission income may be averaged, reduced or excluded depending on its history and the lender’s policy. A move from PAYE employment to self-employment or contracting can require different evidence.
What if my salary is lower in the new job?
A lower salary does not always mean the mortgage cannot proceed, but it can reduce the amount you can borrow, delay approval or mean the requested loan is no longer affordable. The lender will look at income and expenditure together, including how it treats variable pay and any period without income between jobs.
A larger deposit can reduce the loan required, and a good credit history can still be relevant to an application. Neither removes the need for the lender to assess affordability or guarantees that the terms will stay the same. If your income falls, speak to the lender or mortgage adviser before committing to the change so you understand the likely effect on your borrowing amount.
How to prepare for a job change during a mortgage application
The best time to raise a planned change is before it happens, while there is time to check the lender’s requirements. Do not delay telling the lender merely because you have an AIP/DIP or a formal offer: the relevant boundary is completion. A mortgage adviser can help you ask the lender what evidence it needs, but the lender decides whether and how the change affects the application.
Check the lender’s employment criteria
Lender policies differ, so ask about the new role before relying on the current lending terms. Relevant details may include whether the contract is permanent or fixed term, whether it includes probation, the start date and whether your pay includes variable elements. This is particularly important if you will be self-employed, contracting or have a gap between roles.
Prepare the documents the lender requests
Document requirements vary by lender and by your circumstances. An indicative checklist can include:
- a signed contract or appointment letter showing the salary, start date and contract or probation details;
- recent payslips and bank statements for the period the lender requests;
- a P60 or employer confirmation, if requested;
- evidence of variable pay; and
- relevant employment history and any gaps in employment.
If you have not yet received your first payslip, some lenders may consider a contract or appointment letter instead. Ask what they will accept for your application rather than assuming a standard list will apply.
Summary
A job change is not automatically a barrier to a mortgage, but it can affect affordability and the evidence a lender needs. Tell the lender or mortgage adviser promptly about changes during the application and after an offer until completion. Check the lender’s criteria, provide the documents it asks for and get advice early if lower pay could make the mortgage difficult to afford.
FAQ
Frequently asked questions
When should I tell my lender about a job change?
Tell the lender or your mortgage adviser promptly about employment or income changes during the application and after an offer until completion. Check your application declaration and offer conditions, including for known future changes.
What happens if I change jobs after an AIP or mortgage offer?
An AIP/DIP is provisional, not a formal offer. A change can mean the lender needs updated information or an affordability reassessment; discuss it before relying on the existing lending terms. A formal offer can remain subject to lawful conditions until completion.
Can I get a mortgage while on probation or starting a new job?
Some lenders can consider a new permanent role, probation or a signed future offer, but their criteria and evidence requirements differ. There is no single UK waiting period, and consideration is not a guarantee of approval.
Will a lower salary affect my mortgage?
It can reduce the amount you can borrow, delay approval or mean the requested loan is not affordable. The lender considers income, expenditure, variable pay and any gap in earnings; a deposit or credit history does not guarantee the same outcome.
What documents do I need after changing jobs?
Ask the lender what it needs. It may request a contract or appointment letter, payslips, bank statements, a P60 or employer confirmation, and evidence of variable pay or employment history. Some lenders may consider a contract before the first payslip is available.
