Basically. As long as the room is lit by tungsten or indirect daylight you're all set. I took a workshop years ago where we coated paper and dried it in a very bright classroom situation. We did process in a darkroom (school campus), but you don't need one. Haha! Yeah, I guess that could be an issue in the UK. If sun is not a viable option, you could build a UV lightsource or buy one, of course. If pt/pd printing is of interest to you, I'd highly recommend "Platinum & Pallidium Printing" by Dick Arentz.
