tidying up pipes!!

[thebarber]

i'm in the process of fitting a new bathroom, the combi boiler is in there aswell & the pipes (cold feed, hot & 22mm flow / return) are above the floorboards.
it's not a major thing, i just wanna clean the place up & bury them.
SO, is it ok to cut the pipes under the boiler & join to something like PEX or PB (plastic pipe), and which brand is recomended.
Is this stuff ok for central heating? i've used it on taps etc for 12 years now.

Barrier pipe required for CH pipework and consult your models install book for recommendations on using plastic pipe. They will oK it or not and tell you how near to the boiler plastic is permitted.
