The Metropolitan Police said there has been a marked fall in the number of times tasers have been fired, despite figures showing a dramatic increase in usage.
"Despite an increase in usage of Taser over the last two years we have seen a marked fall in firings from 20% in 2010 to 11.7% in 2013," a statement read.
"That means in nearly 90% of occasions where Taser is drawn the mere presence of the Taser was sufficient to bring the situation to a successful conclusion without any direct force being used."
A spokesman added that a programme to extend the use of tasers among trained officers in boroughs has enabled violent or potentially violent incidents to be dealt with far quicker.
