All CAA fees are published on their website. Each time you apply for a licence or rating you have to cough up. I seem to remember our school advising us to apply at the end of all of the training for the ME CPL/IR which saved a bit of cash.
To add to your list - landing fees, approach fees, away landing fees, VFR, IFR charts, protractors, pens, torch, kneeboards, headset rental/purchase, credit card surcharges, accommodation, food, insurance, uniforms? Add on extra flying hours as few will go through in the minimums.
