Replacing the clutch Focus 2.0 Tdci?

My clutch is slipping after only 26,000 miles, unfortuneately its just out of warranty. Been driving 30 years and done high milage on several cars without excessive clutch wear. I wonder if this is a commen problem with the 2.0Tdci due to its high torque. Any problems to look out for in changing it myself. Special tools or access problems.
