Temporary power provider Aggreko was the biggest riser after reporting a 6% rise in its pre-tax profits for 2011.
The company saw pre-tax profits rise by 6% to £327m during 2011 from £320m during 2010.
Rupert Soames, chief executive of Aggreko, gave a bullish outlook for the first half of 2012, but was less confident on the latter half.
He says: “We are confident that the business will deliver strong growth in the first half of 2012; at this early stage of the year, we are more cautious about the second half of 2012, when, in any case, comparatives will be tougher.
“Overall we continue to believe that we will deliver another year of good growth in 2012.” (article continues below)
