It typically costs around $2,500 to add electricals in a new house. This includes the cost of materials and labor. Some factors that can affect the cost include the size of the house, the complexity of the electrical system, and whether or not the contractor has to bring in additional help to complete the job.

It depends on the size of the house and the amount of work that needs to be done, but it can cost anywhere from a few thousand dollars to tens of thousands of dollars. For a smaller home, it might just involve installing some new light fixtures and plugging in a few appliances. For a larger home, or if there's a lot of work that needs to be done ( like rewiring), then it could cost quite a bit more. In any case, it's always best to get an estimate from a professional before starting any electrical work.
