New build Plumbing

I recently watched a YT video on a new kind of push fit fitting. The presenter made a statement that on new builds now all pipework should not involve hot work ie soldering, he went on to say plastic only. Is this correct, can you not use copper even with mechanically fixed fittings such as compression fittings, crimp fittings and what are called in the USA as sharkbite fittings?



Are push fit now that good? I must admit having had a few bad experiences with early versions of push fit so tend to use copper and solder whenever possible.

The plumber my daughter employed for installing central heating and reversing the hot water flow used copper pipes and copper pushfit, with occasional soldering.

I expect they use pushfit because it's quicker. There may also be a ban on hot work on site to reduce paperwork, especially where stud walls are involved.

There's also copper pressfit. About as quick as pushfit but more compact in boiler rooms etc. Also in larger sizes (28mm etc) pushfit gets expensive.
