Thanks all.

These Tectite copper push-fit fittings do look good. But, do you think they could be used (reliably) across the entire system (that is on show)?

I tried these and they were much neater than compression joints for my first attempt. But they can not be undone and I made a couple of expensive mistakes where I had mis-measured some pipe. Hence I undid and went down the solder route.

^ yes one very nice thing about solder joints is you can dry-assemble them as many times as you need before committing.  Non-reversable joints sound like a risky idea for anyone other than an experienced plumber!  Those do look very neat though

P.S.  I was taught four turns of teflon tape for tapered thread joints..

When it comes to PTFE it either leaks or it doesn't.  I use gas tape - less fiddly and less turns.
