running bathroom from mains water

Hi,

I'm soon to rip out the old bathroom suite and replace it with new and was wondering is it possible to tee off the main water supply going to the boiler in the bathroom to provide cold water for the basin, bath and cistern?

If so are there any considerations I would need to take into account? As I understand I would need to put on check valves to stop any reverse flow of water potentially contaminating the mains supply and service valves. Is there anything else?

Cheers,
Simon
