Really? Pipe clips

The problem is actually getting room to swing a hammer or get a screwdriver in the floor void to fix the clips to the underside of the joists.

I find thin galv. steel straps are very useful to fix things where there does not seem to be a purpose made fixing available.  In this situation you would cut off a length of the strap and twist each end through 90 degrees and bend the middle of the length of strap under the pipe and simply nail each end to the side of the joists.  See link below for strap:

The strap can be easily twisted with two pliers or pliers and a vice and cut with tin snips as it is only about 1mm thick.

That's what I had in mind too, although I suspect there could be issues with vibration with these without some sort of padding between the pipes and the galvanised band.

Sort of overkill. I used reclaimed packaging straps (reinforced polyester) for suspending 110mm soil pipe under beam&block floor.

However, when using metal strap it's worth separating it from copper either with insulation or some other soft material (cardboard, plastic)

So, is the consensus that slinging the pipes together, then hooked over a nail, not good practice?

What sort of insulation do I need? And where? I really do need to be taken through this step-by-step.  Until recently I have always lived in rented accommodation and never been allowed to do any kind of DIY or maintenance ( even in the most awful, probably dangerous places.)

Please - we all have to start somewhere.

It seems as though I have had sub-par work done by someone I trusted. That hurts.

Surely ideal. Or - for super-cheapskates - there's even this: https://www.screwfix.com/p/ced-all-round-band-12mm-x-10m/18298

These pipes should obviously be lagged in rigid foam as a matter of course, so that'll take care of any friction noise.

Easy to bend into a coat-hanger shape so pipes run side-by-side, and will be anti-chew, anti rot, and dead easy to attach to the joist with either a nail or a screw.

Yes, you could recycle stuff like packaging banding, but these materials come with a multitude of pains; how do you secure them - you ain't going to get a nail or screw through them with any strength remaining. How do you tie them - they spring open. How do you prevent meece from chewing them?

I'm hoping that this plumber's solution is actually temporary, just to hold the pipes in place whilst he completes the runs. He will be lagging them, surely? And that current suspension method is completely unacceptable.

This is the finalised job.

I asked him to remove some radiators from certain walls, then install new rads on different walls. ( I couldn't re-use the old rads because of relocation measurements.)

I have zero DIY skills and knowledge, obviously. This means getting another plumber in to fix the job properly.

The Yanks use these. They usually have bigger crawl spaces to work from, so it makes sense to have them clear of the joists for spray insulation and maintenance.

I am appalled. Gobsmacked.

And no insulation?

What did this guy charge you? Was there any detail in their quote?

I have no idea whether folk should expect new pipes to be insulated - surely they would?! No plumber of integrity is going to do an installation and then say, "Insulation is extra, pal. And so are clips..." That's nuts. Congrats - you have met a bona-fide cowboy.

Ok, yes, you do need another plumber - and to leave an honest review for the other one. With photos.

Please please come back and tell us what the new fellow says. Pleeeeez. Better still, video the look on their face.

Finding another plumber...... Oh joy.

The one I trusted came highly recommended. 

Right folks, in words of one syllable, what EXACTLY do I need doing?

Shall I also show you photos of how my drilled up floor is looking?

That's fine IMO. No consensus then.

Foam insulation. Around each pipe under the floor.

Galvanised steel shouldn't be used in direct contact with copper or brass though.
