I just wanted to report back on this matter, just in case anyone searches and comes upon it.
What I did in the end, was a two prong approach. As I had a guttering issue too - I found a local exterior cleaning company who turned up the morning after I rang them, treated the problematic path with some chemical, then sprayed it with an industrial pressure cleaner. Looked fabulous when they'd done. They went up a ladder and cleaned out and flushed all my guttering. They took all the gunk away with them and cleaned up after themselves. I was extremely happy with the results.
After a few days, when it was dry for a while, I applied Wet and Forget to the more critical stretch of path initially, as I wasn't sure how far it would go and just made a 6 pint batch. I had just about enough left to spray a garden bench and table and you can see already, after about 10 days, how it has already improved the bench itself - which was green - I didn't really do it that thoroughly as it was running out of liquid. The improvement there was visible the following day - the concrete took a little longer and the overspray itself was enough to improve it visibly. The other photo is a bit of moss at the edge of the path that I'd sprayed and which is clearly dying back.
I was hoping to do more today, but it's just remaining so damp, the ground just isn't drying enough - especially where I'd swept leaves, it was sodden. My large spray bottle worked well and I'll be very happy if I can do this a couple of times a year to keep it at bay.
Thank you for the assistance. I was very happy today when I went out and saw those two areas.

You mentioned the pressure washer is messy - maybe try a patio cleaner attachment if you fancy trying again in future to save yourself money. Hopefully your wet/forget stuff will stop it getting as bad as it was.1

I also mentioned earlier that I wasn't sure I'd be able to get it up the cellar stairs - but having actually got it out, I realise that it's possibly lighter than my handbag, so that's not going to be an issue either - it's much dinkier than I'd visualised from memory.
I'll certainly try it myself at some time - I'm on a steep learning curve at the moment, but rapidly acquiring new skills. I'll give it a try when my son is here, as I may need to set up a system, or adapt a tool, to help me get the hose in position etc. on my own, as I have to pass it over a tall wall and through a tree.
