Factors affecting the cost of rewiring a house

You need to consider several other factors in getting your house rewired. Here are some of them.  


Where you live will influence the overall house rewiring costs. For example, rewiring expenses may be cheaper if you’re from the northern part of England. The closer your home is to a highly-urbanised city like London, the higher your bill may run. 

Property size

Another house rewiring cost factor to consider is the size of your house. The size of your house will ultimately give your contractor an idea of how many wires your home has. Hence, the amount of work needed determines the full house electrical rewire costs. Expect the expense to be higher if you’re looking into costs to rewire a commercial building.


Unbeknownst to some, different materials are used for electrical rewiring. These include tape, electrical boxes, cable hangers, splices, and wires like copper. The more materials used, the more expensive the job is. You shouldn't compromise your safety to save a few bucks. It's better to spend a couple of dollars for more quality services. 

Other services

The truth is most people get their house rewired only after an emergency. Additional services like electrician call-out fees, emergency services or after-hours will be charged as they require more urgent attention. Extra fees also come if you need to install sockets and switches.
