What does rewiring a house involve?

Do you live in a 25 years old property? If yes, then you should find out whether or not it has been rewired within the last 25 years. If not, it’s very possible that the buildings electrical wiring will need to be upgraded to bring it up to the current standards and demands of modern electrical devices. What’s more, If you’re extending your property or converting your loft, you’ll have to ensure that your new wiring conforms to the regulations laid down in the UK government’s Part P: Electrical Safety document. In other words, this implies that all current wiring will also have to be upgraded to ensure it carries the extra demands safely. In this post, we’re going to give you a good insight into the house rewiring process. Let’s take a look!

An entire house rewire is usually carried out by an electrician and involves removing all the existing electrical wiring in all the rooms of the home. Features such as sockets, lights and switches are also detached and updated to modern ones. The removal process can be quite destructive because the wall will have to be chased or channeled out for the wiring to be concealed inside them and floorboards will also have to be removed to enable the installation of the cables. As a result, the best time for a rewiring project is when redecoration has also been planned. Rewiring also means that you can move and install more power outlets, switches and light fixtures. This also gives you the option to install modern smart plugs as well as switches.

Benefits of rewiring?

Long before the emergence of advanced technology in the form of TVs, computers as well as security systems, older homes were already built and in existence. As a result, it often happens that these powerful amenities are used in homes that still have old electrical wiring installed. Although, your home may have a traditional or classic look, to enjoy the best amenities you’ll likely need to change its wiring. In other words, even if you’re living in an older home, it’s still very possible to make use of modern appliances and electronic technology by investing in a total home rewire. We’ve listed below some of the benefits associated with rewiring projects in order to help you make the best decisions.

  • Improved electrical capacity. If you happen to live in an older home or property, then chances are your property’s wiring won’t be able to handle your modern electrical needs. It’s simply impossible to compare a home built in the 1960s which is likely to have a maximum electrical capacity of 60 amps to today’s houses built with 100 amps electrical capacity. Therefore, rewiring your home gives you a greater electrical capacity to incorporate the modern technology.
  • Improved safety. This is one of the greatest advantages of rewiring your home. As you would expect, older rewiring and electrical systems are more prone to a variety of faults which is likely to be a danger to you and your home. Rewiring lets you add and update your home’s other safety measures like special wiring and more.
  • Safer remodelling as well as extensions
  • Potentially cheaper home insurance
