When I load up a tilemap Construct 2 crops the image incorrectly. I have tried adding additional size to the outside of the image but it makes no difference. It seems to cut off a few pixels on the width without fail. Any thoughts please?

It would really help us to help you if you either posted some screenshots of what you mean, or more preferable, post a .capx for us to test.
Not posting enough information just invites lots of guesswork from those trying to help.
There are two solutions :
1- When you place the tilemap, don't work on it first, but crop it perfectly before using it
2- Make the tilemap with a program like "Tiled", you will be able to edit it freely
