I'm about to re-plumb my bathroom, it would be much easier to use plastic pipe as I want to keep all the pipes out of site underneath the floor boards. My concern is with the reliability of pushfit and plastic pipes, from Screwfix, for hot and cold water. Are they as reliable as copper pipe and compression fit connections?
Any advice/comments appreciated,
thank you,

I did the hot and cold water supply for my utility room in plastic (Acorn - equivalent to today's Hep2O) in 1989 - and it's still going strong. I've recently done a downstairs bathroom for my 95-year-old father-in-law - again using plastic pipe. This time, I used Speedfit barrier pipe (from Screwfix) because it also included an extra radiator on the central heating system. [Unless my memory has faded in 16 years, barrier pipe seems somewhat less flexible than the original Acorn pipe - so, if you need to feed it into awkward places, it may be a good idea to avoid barrier pipe unless you're doing a central heating system.]
In places where I've wanted the neatness of copper pipe and the convenience of push-fit, I've used copper push-fit fittings - and these have always been ok.
Speedfit pipe (and, presumably, other PEX systems) are inherently less flexible and more springy than Acorn/Hep2O PB systems. Also Speedfit is only available in barrier (AFAIK) whereas Hep2O is available in barrier or non-barrier - though the barrier version is still much more flexible than PEX.
Why? There is no reason to do so. I use products from several different manufacturers interchangeably, with no problems. 15mm is 15mm.
The tolerates may be different from maker to maker

That's interesting. I had assumed the difference ion flexibility to be due to barrier vs non-barrier - but it could well simply be a difference between Hep2O and Speedfit.
Not by any significant amount. Take a look at how pushfit fittings grab and seal. There is a very large margin there. Most 15mm fittings will happily grab and seal 14mm pipe.

Thank you all for your advice and comments, I've decided to use copper pipe, it'll take longer and be more frustrating, but I'll have better piece of mind. The last thing I want is to have a leak in my new bathroom.
