No you do not need a permit. The problem you might have is that the cold supply in your bathroom is feed from the tank in the loft unless you have a combination boiler which should mean that your bathroom taps are mains pressure. If this is the case then it can be taken from the pipe work in the bathroom for about £60-£80 i would say.

i have never heard of needing a permit unless its not your house and i would not pay more than £50 for it

no you do not need a permit, unless you live in a conservation area. Supplied and fitted should be around £40

nope nothing needed to do this, just needs to have an isolation valve and a check valve to comply with regs, any plumber doing this would automaticly fit these. you shouldnt be looking at any more that £60 supply and fit

No permit is needed....As for price this could be anything from £40 to £80 depending on the Plumber/Builder.

Get a couple quotes.
Good luck.
