Detectives in the UK police service work across Criminal Investigation Departments (CID) and specialist units from DC to DCI and beyond. This guide covers detective salary scales for 2026/27, take-home pay after income tax and National Insurance, the Police Pension Scheme 2015, London weighting, student loan deductions and career progression from DC to Detective Superintendent. All figures are estimates based on standard England and Wales rates -- use the linked calculator for your precise take-home.
Detective Salary Scales UK 2026/27
Detective pay follows Police Pay Review Body (PPRB) national scales for England and Wales. Metropolitan Police and City of London Police pay London supplements on top of these figures.
Senior leadership; major incident command; HOLMES; strategic decision-making
Detective Superintendent (DSuPT)
£75,000--£82,000+
Gold command; serious/organised crime; ROCU; BCU command team
London-based detectives (MPS, City of London) earn higher figures due to London weighting and Metropolitan supplements. Detective Superintendents and above are Chief Officer grade.

Police Pension Scheme 2015 contributions (12.44%--13.78% of gross) will reduce these figures further but contributions are made from pre-tax pay, partially offsetting the cost. Use the take-home pay calculator for your exact figure.
Police Pension Scheme 2015 -- Impact on Take-Home Pay
All detectives in UK police forces are automatically enrolled in the Police Pension Scheme 2015 (PPS 2015), a Career Average Revalued Earnings (CARE) defined benefit scheme. PPS 2015 replaced the more generous final-salary PPS 1987 and PPS 2006 for new joiners. Employee contributions under PPS 2015 are tiered by pay band:
--Up to £27,000 gross: 12.44% contribution
--£27,001--£60,000 gross: 13.44% contribution
--£60,001--£150,000 gross: 13.78% contribution
Auto-enrolment minimums (5% employee, 3% employer, 8% total) are far exceeded by PPS 2015 -- the scheme's employer contribution is approximately 31% of payroll, reflecting the genuine value of a guaranteed defined benefit pension with inflation-linking and survivor benefits.

Pension value note: Despite the high contribution rate, PPS 2015 is extremely valuable. With a normal pension age of 60, inflation-linked annual pension, lump sum options and spouse/dependant benefits, the total employer cost equivalent is around 31% of salary -- far exceeding the auto-enrolment minimum of 3% employer contribution.
Student Loan Repayments for Detectives
Police Constable Degree Apprenticeship (PCDA) and Police Degree Holder Entry Programme (DHEP) graduates, as well as those who completed a policing degree before joining, may have outstanding student loans. Repayments are deducted via PAYE alongside tax and NI.
--Plan 2 (graduates 2012--2022): 9% on earnings above £27,295/year. A DC on £30,000 repays approximately £243/year (£20/month). A DS on £42,000 repays approximately £1,323/year (£110/month).
--Plan 5 (students from 2023): 9% on earnings above £25,000/year. A DC on £30,000 repays approximately £450/year (£38/month).
--Plan 1 (pre-2012 graduates in England/Wales): 9% on earnings above £24,990/year. A DC on £30,000 repays approximately £450/year.
Note that PCDA apprentices do not take out student loans for their degree -- the degree cost is funded by the force. Only officers who self-funded a policing or related degree before joining via the non-apprenticeship route will typically have Plan 2 or Plan 5 student debt.
Regional Pay -- London Weighting and Force Variations
Detective pay varies by region primarily because of London supplements. The Metropolitan Police Service (MPS) operates its own pay scale, with a DC starting at £34,627 rising to £46,707. This compares to the national starting pay for a PC/DC of £29,200. London-based detectives therefore earn substantially more in gross pay than their colleagues in other English forces.

Scottish Police Pay Review; Scottish income tax rates apply
Higher London pay is partially offset by London's higher cost of living and the fact that higher gross pay attracts more income tax at the same marginal rates. A London DC on £34,627 takes home approximately £27,600/year after tax and NI -- around £2,500/year more than a national-scale DC on £30,000. The pension cost (as a % of salary) is the same regardless of region.
Scotland applies Scottish income tax rates, which differ from England and Wales. Scottish taxpayers pay a starter rate of 19%, a basic rate of 20%, and intermediate rate of 21% (£27,491--£43,662), meaning Scottish detectives at DS grade pay slightly more income tax than their English counterparts at equivalent salaries.
Career Progression: DC to DCI and Beyond
Most detectives join via the uniformed constable route, completing probation as a PC before applying to transfer to CID (Criminal Investigation Department) as a DC. Forces also recruit directly into detective roles via the Detective Constable Direct Entry scheme (piloted in several forces) or through the DHEP (Degree Holder Entry Programme) with a pathway to CID.
--DC to DS: requires National Investigators Examination (NIE) Parts 1, 2 and 3 plus a promotion process. Typically takes 3--7 years from joining CID.
--DS to DI: competitive promotion assessment; leadership skills increasingly important. DI is the threshold for tactical command of major incidents.
--DI to DCI: strategic leadership assessment; HOLMES coordination; command of serious/complex investigations including murders and organised crime.
--DCI to Detective Superintendent: senior leadership; ROCU (Regional Organised Crime Unit) command or BCU command team. Salaries £75,000--£82,000+.
Specialist detective roles -- such as those in the National Crime Agency (NCA), GCHQ-linked units, Counter Terrorism Policing or Serious Fraud Office -- may offer different pay scales and allowances, and in some cases (NCA) operate outside the standard police pay framework.
Frequently Asked Questions
Frequently Asked Questions
What is the take-home pay for a Detective (DC to DCI) in 2026/27?
Entry level (DC, ~£30,000 gross): approximately £25,120/yr (£2,093/mo) after income tax and NI. Mid-career (DS, ~£42,000 gross): approximately £33,760/yr (£2,813/mo). Senior (DI/DCI, ~£65,000 gross): approximately £48,257/yr (£4,021/mo). These figures exclude pension contributions and student loan repayments.
What are the detective pay scales in the UK for 2026/27?
Detective pay follows the Police Pay Review Body (PPRB) recommended scales, which are mirrored in the Police Federation agreement. Detective Constable (DC) typically earns £29,200--£43,000 depending on spinal point and time in role. Detective Sergeant (DS) ranges from approximately £46,200 to £48,200. Detective Inspector (DI) earns approximately £57,000--£60,000. Detective Chief Inspector (DCI) earns £65,000--£70,000 or more. London-based detectives receive an additional Metropolitan Police Service (MPS) or City of London supplement on top of these national figures.
How much tax does a Detective Constable pay?
A DC earning £30,000 gross in 2026/27 pays approximately £3,486 in income tax (20% on £17,430 taxable income above the £12,570 personal allowance) and approximately £1,394 in employee National Insurance (Class 1, 8% on £17,430). Total deductions before pension: £4,880, leaving a net take-home of approximately £25,120 per year (£2,093/month).

What is the Police Pension Scheme 2015 and how much does it cost?
The Police Pension Scheme 2015 (PPS 2015) is a Career Average Revalued Earnings (CARE) defined benefit pension. Employee contributions are tiered: 12.44% on earnings up to £27,000; 13.44% on £27,001--£60,000; 13.78% on £60,001--£150,000. These are significantly higher than typical private sector pension contributions but come with a guaranteed retirement income, inflation protection and a lump-sum death benefit. For a DC on £30,000, the contribution is approximately £3,732/year, reducing net take-home to around £21,388/year. The employer contribution rate is approximately 31%, making the total pension package one of the most generous in the UK public sector.
Do detectives in London earn more?
Yes. Officers serving with the Metropolitan Police Service (MPS) receive a London Weighting allowance and, at some grades, a London Pay addition. The MPS starting pay for a constable is £34,627 rising to £46,707 on the Metropolitan scale, compared to the national starting pay of £29,200. Detective ranks receive equivalent London supplements. Officers in the City of London Police also receive London pay scales. These London-specific figures apply after the same income tax and NI deductions, so the take-home advantage is partially offset by proportionally higher tax at higher pay points.
Do detectives have to repay student loans?
If a detective graduated from a UK university after 1998 and has an outstanding student loan, repayments are deducted via PAYE alongside tax and NI. Under Plan 2 (most graduates since 2012), the repayment rate is 9% on earnings above £27,295/year. A DC earning £30,000 would repay approximately 9% of (£30,000 minus £27,295) = £243/year (around £20/month). A DS on £42,000 would repay approximately 9% of £14,705 = £1,323/year (around £110/month). Plan 5 (new students from 2023) has a threshold of £25,000; repayments on that plan would be slightly higher.
How does detective pay compare with uniformed police officer pay?
Detective grades broadly mirror uniformed ranks: DC = PC pay scale, DS = Sergeant pay scale, DI = Inspector, DCI = Chief Inspector. In practice, many detectives receive detective-specific allowances (Detective Supplement, National Investigators Allowance) which add to their base pay and make detective roles marginally better-paid than equivalent uniformed ranks. The Detective Supplement is approximately £1,500--£2,500 per year for DCs and DSs in many forces, though the exact figure varies by force and is subject to local negotiation via the Police Federation.
What happens to take-home pay if a detective opts out of the Police Pension Scheme?
Opting out of PPS 2015 removes the employee contribution (12.44%--13.78% of salary), which substantially increases monthly take-home pay. However, opting out also removes all pension benefits, death-in-service cover and ill-health retirement provisions. Officers who opt out may be auto-enrolled into an alternative workplace pension (usually a defined contribution scheme at the auto-enrolment minimum of 5% employee, 3% employer). This would reduce the take-home increase but remains lower than PPS contributions. Financial advisers generally caution against opting out of defined benefit schemes of this generosity.
Can detective pay push someone into the higher-rate tax band?
Yes. The higher-rate income tax threshold in 2026/27 is £50,270. Detective Inspectors and Detective Chief Inspectors typically earn above this threshold. A DI on £58,000 pays 40% income tax on earnings above £50,270 (the basic rate band of £37,700 sits between £12,570 and £50,270). This means a DI on £58,000 has an effective tax rate significantly higher than a DC on £30,000. On £65,000 gross, income tax is approximately £13,432, NI approximately £3,311, leaving take-home of approximately £48,257/year (£4,021/month) before pension contributions.
What overtime and allowances affect detective take-home pay?
Detectives can earn additional income through: overtime (calculated at time-and-a-third or time-and-a-half on rest days/bank holidays depending on force policy); the Standby Allowance for being on call; the National Investigators Allowance (NIA) paid to investigators who maintain CPIA competencies; the Detective Supplement paid at DC and DS level in many forces; and Unsocial Hours allowances for working nights and weekends. All these payments are subject to income tax and NI via PAYE in the normal way, but can add £2,000--£8,000 to annual gross pay for active CID or specialist detective unit officers, meaningfully increasing take-home pay.
Disclaimer: All figures on this page are estimates based on 2026/27 HMRC rates for England and Wales.
