After a CH install I've lifted the floor boards to find the central pipes unsecured and not insulated. The pipes are not even run next to anything to be secured to, and the access to the crawl space has been blocked with pipes. What's the best solution here. Should I rerun the pipes and clip them? Are there specific rules or regulations for securing CH pipes? What's the best way to insulate them? Any advice very much appreciated.
 
Is it copper or plastic?
nail clips or hinge clips, cut noggins between joists if needed.
Standard pipe insulation is fine in most cases
 
If pipes are run parallel below the space between joists, you could make a wooden U shape frame fixed to joists & screw pipe clips on lower horizontal piece of wood.
 
All round band and insulation
 
Ideally it should be run like these but to often pipes are shoved through hatches , insulating is normally done in the ground floor void in foam or hair felt wrap this all takes time and patience, I alway taught my youngster to run pipes as you would above ground as much as possible supporting them well adding section of felt where you can get rubbing on joists from expansion and contraction .

its copper

yes but i think they need to be clipped every 1.2m which means a lot of wood to cut and seems like a bit of a bodge. Would it not be better to rerun the pipes next to joists and clip them? Is there a problem insulating clipped pipes under floors?
 
Get the installer back to finish the job ?
That would be nice but I'm worried about his competence and every time I ask him something he tries to pull the wool over. He's put false reedings on the paperwork and now I've had the gas inspector out we've found low pressure from a faulty gas pressure regulator as well as a faulty gas main, which he must have knew about. Inspector won't look at a lot of the issues because he claims it not in his remit.
