Detective Allowance and Specialist CID Payments
The Detective Allowance is a non-consolidated payment made to officers who hold a detective warrant and are working in a detective role. It compensates for the nature of detective work — which typically involves irregular hours, on-call commitments, and the demands of complex investigations that do not fit neatly into shift patterns. The DA is paid as a weekly or monthly supplement on top of the officer's basic rank pay and is a defined, recurring component of detective remuneration.
The treatment of the DA by mortgage lenders is variable and is one of the key points that distinguishes specialist emergency service brokers from generalist advisers. Some lenders include the Detective Allowance in full as a permanent supplement to basic pay, recognising that it is paid consistently and is directly tied to the substantive detective role. Others apply a percentage discount, treating it as a supplement rather than core pay. The best-informed lenders — those with experience of police applications — will include it in full and understand why it is a permanent feature of a detective's pay.
Officers in specialist units within CID — Major Crime, Organised Crime, Counter Terrorism, Cybercrime, Child Protection, and others — may receive further allowances specific to their role. These can include payments for carrying specialist equipment, on-call responsibilities, or skills requirements such as firearms qualification or surveillance training. Each of these payments represents a recurring, role-based supplement that should form part of the income picture presented to the lender.
Plain clothes allowance — where it remains in force in particular constabularies — and expenses associated with maintaining a plain clothes appearance are separate from pay for income assessment purposes and would not generally be included in a mortgage calculation. Your broker will help distinguish between genuine pay components and expense reimbursements when preparing your income documentation.
Overtime Patterns for Detectives — Why They Differ from Uniformed Officers
Police overtime for uniformed officers tends to follow relatively predictable patterns — finishing late on shifts, working planned public order operations, or covering during shortages. Detective overtime is structurally different. Major investigations — murders, serious sexual offences, large-scale frauds, complex organised crime operations — can generate intensive periods of overtime lasting weeks or months, followed by quieter periods between cases. This irregular but often very substantial overtime pattern means that annual overtime figures can look volatile on a year-by-year basis, even when total overtime across a career is substantial.
Lenders who are not familiar with detective work may see the variability in overtime and apply a heavy discount or exclude it entirely, citing inconsistency as a reason not to include it in the affordability calculation. This is an overly conservative approach that fails to understand the nature of CID work. A broker experienced in police detective mortgages will know how to present the overtime history accurately — using P60 data across multiple years to demonstrate that while the timing is irregular, the amount over time is consistent and likely to continue.
Court attendance fees are a further income component that arises from the detective role. Officers attending court — whether for evidence in criminal trials, inquest proceedings, or civil matters arising from their investigative work — receive attendance fees that can add meaningfully to annual income, particularly for experienced detectives who carry large caseloads with regular court appearances. These fees may appear as separate payments on payslips or as additional earnings through the payroll system.
If you have had an unusually high-overtime year due to a specific major investigation, it is worth flagging this to your broker so that the income figure is contextualised. Equally, if you have had an unusually low year for reasons that do not reflect your typical earnings — extended sick leave, secondment to a non-detective role, or a particularly quiet investigative period — this context helps lenders understand what your sustainable ongoing income looks like.
