Germany Trade and Invest (GTAI) linked the increase to Britain's departure from the European Union on January 31, and said the number of planned new jobs may rise as some firms registered plans directly with Germany's 16 federal states.
"We are witnessing a constant increase in the activity of British companies in Germany," said GTAI chief Robert Hermann.
Some companies were moving to Germany to skirt tariffs that could be imposed on British goods and services once Britain leaves the EU while others were attracted by favourable conditions, Hermann added.
About a third were finance and business services companies, just under a third specialised in IT and some 40% were a mix that included engineering and consumer specialists.
Britain's parliament has approved a divorce settlement with the EU, which includes a business-as-usual transition deal covering the period after Brexit Day on Jan. 31 until the end of December.
Hermann said British business leaders appear undeterred by Germany's weakening economy, whose export-oriented manufacturing sector is in recession.
Germany is Britain's second-biggest export market after the United States.
