British construction output fell 11.6 percent on the year in August, non-seasonably adjusted data from the Office for National Statistics showed on Friday.
Compared to July, construction dipped 0.9 percent after a 2.1 percent month-on-month rise in July.
Between June and August construction output dropped 11.9 percent compared to the same three months in 2011, with the main drag coming from a 15.6 percent slide in new work.
The ONS warned that caution should be taken when interpreting movements in output involving June 2012 because a May public holiday was postponed until June, when another day was added to celebrate The Queen's Diamond Jubilee.
A steep slump in construction output was the main drag on Britain's economy in the first half of 2012, pushing the country back into recession.
