Illustrative scenario, not a real client case or a mortgage offer. Owen Marsh is a fictional HMPPS prison officer in England. He and his partner, Beth, would like to buy nearer her family. Imagine Owen is discussing a transfer to another prison and his present pay includes a market supplement. He has found a salary figure online, but it is not yet clear whether he is comparing like with like.
Check what the headline figure includes
Owen could start by setting aside the headline and asking for a breakdown of the proposed post. What would his contracted hours be? Which regular payments would apply? Would the figure include unsocial-hours pay, and would there be a supplement at that establishment? Until those questions have answers, adding separate figures together could produce a misleading total.
The official prison officer pay page explains that its published starting figures already include an unsocial-hours allowance and, where applicable, a market supplement. It also distinguishes contracted hours. Those tables should not be treated as a personal pay confirmation. This example concerns HMPPS in England and Wales, not every UK prison employer.
A familiar payment can still be location-linked
In Owen's imagined circumstances, the supplement has appeared regularly enough that he thinks of it as ordinary income. That is understandable. Yet the same official guidance says market supplements at qualifying prisons are separate from base salary and may be withdrawn. A transfer would therefore be a good moment to ask exactly what would continue.
Owen could request written confirmation of his proposed pay components and their start date, including whether any pay protection applies to him. He should not assume that it does. If the receiving prison cannot yet confirm a component, he and Beth could mark it as uncertain in their planning instead of quietly carrying forward the old total.
Separate agreed hours from optional extra shifts
Suppose Owen currently works overtime when family commitments allow, but expects to do less after moving. His useful evidence pack could separate contracted hours from those additional shifts. He could gather the transfer correspondence, current payslips and a short explanation of the changes being discussed. The exact documents and period required would need checking with the proposed lender.
A question such as 'Would these hours be written into my contract?' would help Owen understand his own position. Another would be 'Am I planning to keep doing this overtime?' There would be little value in planning the new household around extra shifts he already hopes to stop.
Let the move change both sides of the budget
Living nearer Beth's family might alter their childcare arrangements, but they should ask what help is genuinely available before putting a lower cost into the budget. Owen's travel could change too. They could compare the expected household costs with confirmed future income, then try the same exercise without the disputed supplement or optional overtime.
If the purchase still appeared manageable, a possible next step would be a lender criteria enquiry using the actual transfer details. If it depended on unresolved pay, waiting for confirmation or considering a cheaper property might deserve a closer look. These are alternatives to investigate, not evidence that a particular borrowing amount would be accepted.
Take a clear question to the adviser
Owen could summarise the issue in a sentence: 'I may transfer before buying, and I need to know which parts of my new pay can be evidenced.' He could then ask how the application should be updated if the transfer date, hours or supplement changed. Employment terms are relevant; confidential prison information is not needed for that initial discussion.
