How much does a police detective earn in the UK? Salary, ranks and benefits explained

Police detectives work in some of the UK’s most interesting and varied investigator roles. They play a vital part in solving serious crimes, protecting vulnerable people and bringing offenders to justice. But if you’re considering this as a potential career option, you’ll probably want to know what you can expect in terms of pay, benefits and progression.

Whether you’re looking to join through a direct entry scheme or progress from a uniformed officer role, it’s important to understand how earnings can vary by rank, experience and location. Here’s what you need to know about how much these professionals earn and what other financial and career benefits come with the role.

What does a police detective do?

Detectives are responsible for investigating serious and complex crimes, working across a range of specialist units within UK police forces. Their duties typically involve gathering and analysing evidence, interviewing suspects and witnesses, preparing case files and supporting prosecutions.

There are many paths within this field. Common detective roles include working in the Criminal Investigation Department (CID), safeguarding units, major crime teams, counter-fraud and specialist operations such as counter-terrorism. Traditionally, detectives are drawn from serving uniformed police officers who have completed the necessary training courses. However, there are also several direct entry pathways, such as graduate schemes, for those without experience in uniform. 

The work is varied, often demanding, and requires strong analytical, communication and case management skills.

Starting salary for police detectives

The starting salary for a newly qualified Detective Constable in the UK varies depending on location, force-specific allowances and the route of entry. While most detectives begin on the standard Police Constable pay scale, regional differences and additional payments can significantly affect take-home pay. Below are some examples from across the country of the starting salaries new detectives can expect to receive, according to recent job listings and pay scales published by police services.

  • West Yorkshire Police (Police Constable Entry): Starting salary of £29,907, rising to £32,427 after two years.
  • Thames Valley Police: Starting salary of £34,164 for new Detective Constables, including the south-east regional allowance.
  • Metropolitan Police: Starting salary of £40,776, rising to £43,302 after two years and satisfactory completion of probation. This includes London weighting and additional allowances.

How pay increases with experience and rank

Detectives’ pay typically rises within the same rank as they accumulate experience and meet performance expectations. For example, a successful applicant to West Yorkshire Police on the path above can expect their salary to rise to £48,231 after six years, while for an officer in the Met, typical earnings may increase each year to reach £59,994 after five years.

Pay increases become more pronounced if detectives are able to secure promotions to higher ranks. Average pay ranges for more senior staff across the UK as a whole, according to Glassdoor, are:

  • Detective Sergeant (DS): Base pay between £44,000 and £53,000, plus an average of £4,000 in additional pay.
  • Detective Inspector (DI): Base pay of between £52,000 and £67,000, depending on force and experience.

Performance reviews, years in role and regional allowances all contribute to progression, rewarding dedication and promotion with significantly higher earnings.

Regional variation in salaries

The figures above provide general guidelines, but actual detective salaries vary significantly depending on location. In London, the Metropolitan Police offers some of the highest starting pay, which reflects the high cost of living in the region. For example, a Detective Constable starts at £40,776, rising to £43,302 after probation, and up to £57,843 within six years.

Similarly, forces in the south-east like Essex and Hampshire include regional allowances. Essex pay starts at £33,914 (including a £2,750 allowance), increasing to around £53,000 over seven years. In contrast, wages in other areas of the UK tend to be lower, reflecting the absence of London or south‑east supplements and lower cost of living.

Additional benefits and allowances

Alongside core salary, police detectives benefit from a wide range of additional allowances, enhancements and long-term financial rewards. These vary slightly by force but often make a significant difference to overall earnings and job satisfaction. Common benefits include:

  • Overtime pay and unsocial hours allowances
  • Pension contributions via the Police Pension Scheme 2015
  • Generous annual leave entitlements
  • Enhanced parental leave and family support policies
  • Training and development opportunities
  • Access to staff discounts, healthcare and wellbeing schemes
