When should I rewire my electrical system?

5 min read

Rewiring a house can surely be a time-consuming and costly project. However, due to the safety risks posed by damaged or deteriorating wiring, it may be necessary. So, do you know when it’s time to undergo an electrical rewiring for your property?

There are no unbreakable rules. The fact that wiring is ancient does not suggest that it is harmful. Wear and tear might differ based on the materials used and past usage.

A periodic inspection by a certified electrician is suggested at least every ten years for an owner-occupied dwelling and every five years for a rental property or at the change of tenancy.

A skilled electrician will determine whether your property requires rewiring and what can be accomplished within a specific budget. See Electrical Installation Condition Reports for more information.

Suppose a home is more than 30 years old and still has the original wiring. In that case, it will certainly need to be updated, at least in part, to meet the current regulations and standards, such as replacing the consumer unit/fuse box with a new fire rated one. Dated rubber, fabric, or lead-insulated cabling is an indication that a rewire is required. A modern wire is PVC coated, grey or white in colour, and twin-earthed. Old and outdated wiring can cause the entire electrical system to trip often, blow fuses, or, in the worst-case scenario, start a potentially fatal house fire or electrical shock.

If you are thinking about buying an older home, be sure the wiring is safe. An electrician can tell you what work is needed to bring it up to current standards and provide pricing estimates that you can use when making an offer. Even newer homes might have issues, such as faulty DIY electrical work.

Electrical rewiring provides an opportunity to increase safety and modern convenience by adding extra switches and outlets for kitchen appliances, home computers, and televisions. A recent rewire might increase the desirability of an older property to buyers if you are selling it.

If you plan an extensive renovation, you will almost certainly need to rewire all or part of your property. Building Regulations BS 7671, commonly known as the IET Wiring Regulations, must be followed while installing electrical equipment. This establishes the criteria for electrical installation in the United Kingdom. Suppose you are extending your home or converting the garage or attic. In that case, all new wiring must comply with the most recent Building Regulations, and the current installation must be updated to carry the additional load safely.

The cautionary signs: Be careful about changes

If you have an older home that hasn’t been examined in a while, it might be time for a rewire. Circuit breakers that trip regularly, minor shocks from switches and outlets, constantly flickering or dimming lights, and damaged or exposed wires and cables are all signs that your home needs to be rewired.

If you notice any of these warning signals, contact an electrician who will determine what work is exactly needed and so to provide you with the service you need.  

Why Is It Necessary to Rewire Your Home?

expansion of electrical capacity

An extremely outdated wiring system typically has a capacity of 60 amps, which is insufficient to support current technology. A considerable weight could cause serious injury. An electrical overload could cause burnt-out products and even house fires. However, upgrading the electrical system to 100 amps should keep you safe and save you money.

Enhance Security

A house rewiring project can significantly increase your safety. Poorly insulated wires can cause shock and fires because of power fluctuations. If there is an overload, the cables can even melt and burn. Inadequate wiring might also make your appliances dangerous to use and cause your smoke detectors to malfunction.

Secure Against the Elements

The insulation on new cables is superior. Brittle plastic insulation or inadequate coatings can be hazardous if temperatures rise too high. You don’t have to worry about heatwaves with the new wires on the market because they are heat-shielded.

Rewiring might help you improve your home’s electrical system

While you’re rewiring your home’s electrical system, you can also wire each device to its circuit. This reduces the likelihood of it being overloaded. Ground fault circuit interrupters and networked, hard-wired smoke and carbon monoxide alarms can also be installed.

Reduce Your Spending

Despite the price of replacing your house wiring, installing newer, safer wiring can result in lower insurance premiums. Because the chance of an accident is smaller, insuring a rewired home is less expensive. Having it rewired first can increase its value by thousands of dollars if you plan to sell your home.

Should I do it all by myself or hire an electrician to rewire my house?

Professional electricians are certified and have completed the necessary credentials to work in the trade. In addition, they have prior experience, on-the-job training, functional abilities, and a specific degree of education that you can rely on, when it comes to your electrical rewiring of your property. Their experience and understanding enable them to swiftly and efficiently find, comprehend, and resolve a wiring problem. After the job is completed, you may be confident that no other issues will arise.

Finally, evaluating a professional’s worth in monetary terms is not advisable. While the cost of their service is considerable, you end up saving more in the long term. A professional will usually do the task correctly the first time, eliminating the need for costly repairs due to mistakes in the wiring procedure or complications resulting from poor quality. Poorly built circuits can wreak havoc on your electrical appliances and equipment, costing you more money to repair or replace them.

A professional is more efficient at his job and completes it faster without damaging your property or injuring himself, saving you time and money. Their work in electrical rewiring is usually guaranteed, which means that if a problem arises later in the wiring, they will usually come and correct it at no extra cost. Most importantly, professional electrician insurance is typically provided by the company, which means that there is no chance of financial claims being made in the event of an injury on the job.
