Rewiring is a very messy job. Hence, it can be quite disruptive. However, you can deal with this by making sure you set a proper schedule for your work.  This way, you can also set measures to work even in the absence of power. Choose to work during warmer months which can prevent the plumbing from freezing. Also, make sure to gather all your tools and remove the furniture before you start the project. If you think switching off power for the whole house is not feasible, you can work on one circuit after another. However, it is safer to work while turning off all the full power.
