1. Why use this guide?

This guide provides advice on how to find records (primarily staff records) of the London Metropolitan Police. The National Archives has a substantial collection of Metropolitan Police staff records, but not all have survived.

The most recent staff records we hold are pension records dating up to 1993.

The Metropolitan Police Force, created in 1829, was the first modern police force in England (provincial police forces in England and Wales were not established until after the County Police Act of 1839). Its original area of jurisdiction covered a seven-mile radius from Charing Cross in central London. Today it consists of the 32 boroughs of Greater London, excluding the City of London.

Records of the City of London police are held at the London Metropolitan Archives.

Metropolitan Police records held at The National Archives are identified by the department code MEPO (there are 46 separate record series within MEPO). You can browse the department and its composite series in our catalogue for an overview of what we hold.

2. Staff records – online

Significant numbers of Metropolitan Police staff records are available online both through our own website and those of our commercial partners. In some instances there is a fee to view and download these records but there is free access at The National Archives building in Kew.

2.1 Metropolitan Police registers in Discovery

Many of the personnel records are in the series MEPO 4 and can be searched by name (using the keyword search box at MEPO 4) and downloaded from Discovery, our catalogue.

Name details were added to our catalogue from an incomplete index created before records were transferred to The National Archives, so not all records can be found by name searching. If you do not find a record by name searching you can still browse the various types of register listed below in Discovery, find an appropriate register, based on dates of joining or leaving, and download a digital copy to look through.

Some of these records contain more information than others and some information may be duplicated in different records. A summary of the typical contents of each sort of record is below.

3. Staff records – beyond online records

There are still many Metropolitan Police Force records that are not available online. Searches for these records begin in our catalogue which contains descriptions of each record with its document reference. This section of the guide provides instructions on how to target your catalogue search to specific parts of the collection so that you can locate a document reference with greater ease.

For more speculative or broader searches you can try an advanced search of our catalogue using keywords (for example, the name of an officer or a police station, or broader terms such as ‘discipline’ or ‘promotion’) and dates, ensuring that you include MEPO in the reference field.

To see these original records you will either need to visit us or, where you can identify a specific record reference, order a copy (charges apply).
