I inadvertantly lapsed last year - when I realised I was "oh no, full GFT..." - was very relieved to find out that the LPC is pretty simple. Handling, PFLs, that kind of stuff. No nav, and so much much shorter than the GFT. Basically if you do the physical thing of flying, you are OK. I think I paid £70 for the examiner, plus the solo rate on the AC.
(My ever present weakness was the PFLs, so if that's yours you might want to practice a few before the LPC).
