1. Organisation
The Metropolitan Police Act 1829 defined the original Metropolitan Police District as an area of about seven miles radius from Charing Cross, London. The second Act in 1839 amended this to include the whole of Middlesex and those parishes in the counties of Surrey, Hertfordshire, Essex and Kent which had parts not more than 15 miles in a straight line from Charing Cross (except the City of London). By 1869 the jurisdiction of the Metropolitan Police was divided into 4 Districts, each of which had a number of Divisions, as follows:
No.1 District: G - Finsbury; H - Whitechapel; K - Stepney; N - Islington; and Thames Division.
No. 2 District: D - Marylebone; E - Holborn; S - Hampstead; X - Paddington; Y - Highgate.
No. 3 District: A - Whitehall; B - Westminster; C - St. James's; T - Kensington; V - Wandsworth.
No. 4 District: L - Lambeth; M - Southwark; P - Camberwell; R - Greenwich; W - Clapham.
There was also an F - Division (Covent Garden) and, in 1886, a J Division (Bethnal Green) was added in 1886. In 1921 Z Division was formed for Croydon which has previously been included in W Division, and in 1965 Q Division was formed for the Wembley area previously divided between T and S Divisions. Division letter codes I, O and U were never used.
The Bow Street Horse Patrol was incorporated into the force in 1836 and operated in the outlying Metropolitan divisions. The second Metropolitan Police Act 1839 converted the River Thames force into the Thames Division, and absorbed the Bow Street Foot Patrol.
The establishment of the Metropolitan Police also had responsibility for the police of the Royal Dockyards and military stations, Portsmouth, Chatham, Devonport, Pembroke and Woolwich, from 1860 until 1934 and Rosyth in Scotland from 1914 until 1926; information about dockyard police prior to 1860 might be found in the civil pensions for artificers and labourers (ADM 23).
Attempts to incorporate the City of London police into the force were unsuccessful and it has always retained its independence (see Other Police Forces below).
A superintendent was in charge of each division, under whom were four inspectors and sixteen sergeants. The regulations demanded that recruits should be under thirty-five, well built, at least five feet seven in height, literate and of good character. The minimum age is usually considered to be twenty years but the certificates of service (MEPO 4/361-477) include recruits as young as eighteen; service before the age of twenty was not considered for pension purposes.
2. Staff records
Metropolitan Police staff records have not survived in their entirety.
Nearly all the staff records detail name, rank, warrant number, division and dates of appointment and removal. Information additional to this has been noted in the records listed below:
2.1 Numerical registers
Numerical registers of warrant numbers 1-3247, September 1829 - March 1830 (MEPO 4/31-32) give the officer's height and cause of removal from the force. Photographs of these documents can be downloaded from the Your Archives section of The National Archives website. Please note that the contents of Your Archives is contributed by users.
2.2 Alphabetical register
1829-1836 (HO 65/26) gives dates of promotion or demotion.
2.3 Alphabetical registers of joiners
September 1830 - April 1857; July 1878-1933 (MEPO 4/333-338). The earliest volumes give names and addresses of referees.
2.4 Attestation ledgers
Ledgers for warrant numbers 51491-146379, February 1869 - May 1958 (MEPO 4/352-360) give signatures of the recruit and witness. Photographs of these documents can be downloaded from the Your Archives section of The National Archives website. Please note that the contents of Your Archives is contributed by users.
2.5 Certificate of service
Certificates for warrant numbers 74201-97500, January 1889 - November 1909 (MEPO 4/361-477) give a description of recruit, date of birth, trade, marital status, residence, number of children, name and place of last employer, previous public service, surgeon's certificate, postings to divisions, dates of promotion or demotion and cause of removal.
2.6 Registers of leavers
March 1889 - January 1947 (MEPO 4/339-351) give class of officer, number of certificate granted if not dismissed (1. Excellent, 2. Very Good, 3. Good, 4. Open, i.e. no comment), date certificate sent to division, number of documents an officer is entitled to, according to regulations, and date documents sent to division. These last two details are phased out around 1913-1914 and the comments on an officer's conduct are no longer expressed numerically. The abbreviation RP stands for 'resignation permitted' and is replaced in October 1920 by RR 'required to resign'. The divisional abbreviation CO stands for 'Commissioner's Office'. Photographs of these documents, and a transcribed index , can be downloaded from the Your Archives section of The National Archives website. Please note that the contents of Your Archives is contributed by users.
3. Pension records
Before the Police Pensions Act 1890, pensions were granted on a discretionary basis. The Act provided a legal right to a pension after twenty-five years service, and a modified pension or gratuity if discharged medically unfit. Pensions and gratuities, 1829-1859, are mentioned in the early series of correspondence and papers (MEPO 5/1-90).
Records of Metropolitan Police pensioners who retired or resigned between 1852 and 1968 and who were granted or (after 1890) qualified for a police pension are to be found in class MEPO 21. These contain detailed personal records, including physical description, date and place of birth, marital status, dates of service. Before 1923, names of parents and next of kin are also given. You can search by name of officer on The Catalogue for MEPO 21 for dates of retirement until March 1889. After March 1889 it is necessary to know the approximate date of retirement to use this series. (The date of retirement can be determined by referring to the register of leavers).
4. Other sources
- An incomplete nominal index of officers, largely drawn from the records listed above, is held in the Open Reading Room. Also held in this room is an index to officers who joined the Metropolitan Police between 1880-1889.

- Police Orders for the period 1829-1989 (MEPO 7) contain notification of personnel matters arranged annually. They are closed for fifty years.

7. Other police forces
Records of other police forces, except the Royal Irish Constabulary, are not public records. Those which survive are held either by the appropriate local record office or the force itself.
- Correspondence relating to colonial police forces can be found in the papers of the Colonial Office but the records of the forces themselves, like those of local forces in this country, are not held here but might well have been deposited in the archives of the country to which they relate.
