I had experience of Karl Tatler on both the Lettings and Sales side and both were awful. The company is staffed mainly by school leavers who are there for several months and then move on. For selling, they charge a premium to other agents saying they offered a ‘superior service’ - if this means not following through on commitments / promises and ignoring calls then yes, they do a good job at that. Curiously, the most amount of viewings we had on the house was in the two weeks notice period I gave them to terminate- pretty sure they were ghost viewings so if I sell to these people via another agent Karl Tatler will seek a cut
