I am trying to get a copy of a will, something I have done before, but now can't remember the process

I have the information from the National Probate Calendar on Ancestry, but not sure if the forms I downloaded a few ago, from HMCS ( Application for a probate search ) are still relevant.
Also the cost now, I paid £5 for the last wills I sent for. Can't seem to find what I want on the HMCS website.
Maybe just having a senior moment, but would be grateful for some advice please.
