Thanks for the input potkettleblack. A lot of those smaller items could just be included under "misc. items" and probably wouldn't come to more than £500 depending on quality/brand and who you buy them from.
I've tried the CAA's website but that thing is a maze to me and I wasn't able to find the information. I was hoping someone here might know off the top of their head or had a link to the information.
One other thing you touched on, landing/approach fees. Roughly how many landings would you carry out during your training? I know it differs from student to student but a rough estimate would do me.
