I think it might depend on the specification...
Small unoccupied 2 bed I would price per point.....occupied 2 bed again per point but a percentage added on for moving stuff, given the choice and having plenty of work on I’d rather not do an occupied rewire.......but as others say it really is how long is a piece of string
Sparks 321 for a total rewrire and the difficulty factor it would be around $ 4.00 a square footWhat’s the average price to price per point and average time scale that people do it in.
