In 1945, B Company HQ Signals was dispatched to Berlin from its parent unit 5 HQ Signal Regiment, which was located in Paris. Within about a year it was renamed Berlin District Signals (British Element), followed by Berlin Area Signals, Berlin HQ Signals, and Berlin HQ Signal Squadron. In 1947, the Squadron was renamed the Berlin Signal Squadron, and retained that title until 1959, when it became 229 Signal Squadron.

It was enlarged to 29 Signal Regiment in September 1983, when the unit took over administrative responsibility for Brigade Headquarters. When the regiment disbanded in January 1991, 229 Signal Squadron was restored to its former independant state, and the people of Wilmersdorf bestowed the honour of Freedom of Wilmersdorf to the squadron.

Following the final withdrawal of British Troops from Berlin in 1994, the squadron moved to Krefeld as part of 7^th Signal Regiment. In 1995, the Squadron deployed to Bosnia as part of 7^th Signal Regiment supporting Headquarters ARRC in Sarajevo in its role as the NATO Implementation Force (IFOR). The Squadron remained in Bosnia until December 1996 before returning to Krefeld.

In June 1999 the Squadron was deployed to Kosovo as part of 7^th Signal Regiment in support of the NATO peace keeping force and returned to Krefeld in November 1999.

The Squadron moved, along with the rest of 7^th Signal Regiment to Elmpt in January 2002 and in April 2005 returned to Bosnia once again to act as the Multinational Integrated Signals Unit for the newly formed European Force (EUFOR) returning to Elmpt in November 2005.
