UK industrial output fell 0.4% in June following a drop in oil, gas and mining production, according to figures from the Office for National Statistics (ONS).
The ONS blamed part of the fall on maintenance in a major oil field.
Compared with a year ago, total production output is estimated to have increased by 1.5%.
Output from the manufacturing sector increased by 0.2% in June, following a 0.6% drop in May.
UK manufacturers have struggled this year due to weak demand from Europe, a high pound and sluggish investment.
Despite the return to growth in June, the chief economist at the British Chambers of Commerce, David Kern, described the manufacturing sector’s overall performance as “mediocre”.
“Year-on-year growth is below 1% and the level of manufacturing output is still almost 5% below its pre-recession peak in the first quarter of 2008.”
