The UK economy grew by an unrevised quarterly rate of 0.7 pct in the third quarter of the year for the fourth time in a row, official figures confirmed today. However, in its final estimate of quarterly GDP, the office for National Statistics revised up its previous estimate of the annual increase to 2.9 pct from 2.7 pct following upward adjustments to business services and finance in the first two quarters of 2006. The annual rate is now at its highest since the third quarter of 2004, when it stood at 3.1 pct. A more detailed breakdown of the national accounts showed that that industrial production, which accounts for around 19 pct of UK GDP, grew by a revised 0.2 pct -- previously estimated at 0.1 pct. In the second quarter industrial production rose by 0.1 pct. On a year-on-year basis, industrial production saw output rise by 0.4 pct. Within the total, the manufacturing sector grew by an unrevised 0.6 pct during the quarter, down on the heady 0.9 pct recorded in the second quarter. Meanwhile, the services sector, which accounts for around 74 pct of the UK economy, rose by an unrevised 0.8 pct from the previous quarter, down on the second quarter's 1.0 pct. On a year-on-year basis, services output grew by 3.7 pct. The construction sector, which makes up around 6 pct of UK GDP saw output rise by 0.7 pct, up on the 0.6 pct previously estimated and the second quarter's 0.4 pct. On a year-on-year basis, output grew by 1.8 pct over the year. On the expenditure side of the accounts, the statistics office confirmed that household expenditure rose by an unrevised 0.4 pct during the quarter -- a steep drop from the 0.9 pct increase in the second quarter.
