Growth in the UK's services sector rose to its fastest pace for four months in November, according to a closely watched survey.
The Markit purchasing managers' index (PMI) rose to 55.9 in November, up from 54.9 in October. Any figure above 50 indicates growth.
The results of the index for the services sector are so crucial because it accounts for roughly 70% of all GDP in the UK economy. Earlier this week, the PMI for the manufacturing sector fell slightly.
Markit's composite PMI, which combines data from all sectors, remained steady at 55.7 - still the highest level since July. Based on its data, Markit believes the UK economy will have grown by 0.6% in the final quarter of 2015, up from 0.5% in Q3.
Markit's chief economist Chris Williamson said: "A welcome upturn in service sector expansion helped counter slower growth in manufacturing and construction in November, suggesting the UK continues to enjoy the 'Goldilocks' scenario of solid economic growth and low inflation.
"The rate of job creation remained resiliently robust in November despite widespread difficulties finding suitable staff and worries about the introduction of the National Living Wage, in turn leading to reports of rising wages.
"For now, falling oil and energy costs are offsetting rising wage growth and keeping a lid on inflationary pressures, but the upturn in earnings growth raises question marks over just how long inflation, and therefore interest rates, will remain low."
