Does my house need to be rewired?

Rewiring the house explained - costs and tips (1)

There are a number of factors that come to mind when a property needs to be rewired.

As mentioned above, a 30 year old property with its original wiring will probably need to be rewired, not only for safety reasons but also to meet modern standards.

If you're interested in buying an older property, a thorough pre-purchase check should be done by a licensed electrician to make sure the wiring is safe.

The recommendation for an inspection is every 10 years for owned property and every five years for rental property; If you are expanding or remodeling any part of your home, all new and updated wiring

must comply with the latest building codes to ensure safety and security.

In addition to improving home security, rewiring also offers the opportunity to improve your quality of life. For example, more switches and outlets can be installed with new wiring, which can increase the number of devices in a home, including televisions, radios, and home computers.

There are several warning signs if you're not sure if your property needs rewiring: Tripping circuit breakers regularly is an important sign, as it can cause current surges, meaning appliances are drawing too much power from the socket. . Also, flickering or dim lights indicate a wiring fault, including broken or exposed wires.

If you spot any of these warning signs, contact our expert electricians for the best experience rewiring your property.

Rewiring the house explained - costs and tips (3)

As a customer, one of the most important things to understand about rewiring is what goes into a total home rewire as plugs and cords are changed as well as wires.

Rewiring the house explained - costs and tips (4)

While it is possible to do the work yourself, we strongly recommend that you hire a qualified, licensed electrician to rewire your property, as an electrician will need to verify this in all circumstances.

Rewiring a property is not for beginners and can have serious consequences if not done correctly, including fire and electrical shock.

This could not only endanger lives, but insurance companies might not pay in the event of a fire because the wiring was poorly and incorrectly done by a layman.

Reconnecting your property is not illegal, but it is regulated by law

“Part P” of the Construction Regulations; The City Council must also verify that it has correctly carried out the work that must be carried out at various points of the facility. They will charge you for this service, stressing that it is best to have your property rewired by a qualified electrician to ensure safety.
