When it comes to selling a house, you will have a lot of expenses to make your property attractive to potential buyers – estate agent fees, legal fees, property staging, and more.

One of the expenses you may have to consider is rewiring your home if the wiring is too old, making it unsafe to live in. This leads to the question: can you sell a house with old wiring? Do you need to rewire your house before you can sell it for a good price?

We are here to answer that question, as well as how much a complete rewire costs and if it will increase the value of your house.

How do I know if house needs rewiring?

It’s a popular misconception that older homes need rewiring. While a periodic inspection every 10 years by an electrician is recommended, there are some signs you can look for which may indicate a rewire is needed.

These include:

  • Rubber or lead-insulated cables,
  • Shocks from outlets and switches,
  • Damaged or exposed wiring,
  • An old fuse box,
  • Flickering or dimming lights,
  • Circuit breakers that frequently trip.

If your property is over 30 years old and still has the original wiring, a rewire is likely necessary before selling.

Not only does this make the property safer, but it is also more modern and attractive to potential buyers. It also eliminates the issue of buyers trying to renegotiate the price after a survey reveals electrical problems.

To get a complete picture of the state of your property’s electrics, an Electrical Installation Condition Report is needed. Costs for this report can range from £150 for a 1-bedroom flat up to £275 for a 5-bedroom house.

What Does Rewiring a House Involve?

  1. Taking out the old wiring and fixtures.
  2. Installing new wiring throughout the property.
  3. Add white finish electrical accessories like switches and socket outlets.
  4. Installing a new metal consumer unit.
  5. Doing minor plastering to fill small holes or re-plastering where necessary.
  6. Testing the circuits and providing a final installation certification to prove the work meets current regulations.

How disruptive is a house rewire?

Rewiring is a big job for homeowners. Different properties require varying amounts of work, but most need walls cut, chased and chiselled. Electricians can cause a mess, but this is necessary.

You’ll need to consider re-plastering and painting it throughout.

You’ll need to consider the full cost of rewiring a property, as well as the fact that it can take up to 15 days. To make the process easier, try to remove as much furniture as possible, such as carpets and floorboards.

There are extra expenses, such as storage units and a professional for refitting the carpets and floorboards. It is also likely that you will have to move out during the rewiring, as it means your property won’t have power, making it inhabitable.

All of this adds to the cost of rewiring your property. You may be wondering if it’s possible to sell a house with old wiring to avoid these costs and the disruption of two weeks in your home – only to put it on the market afterwards.

If your property is over 30 years old and still has the original wiring, a rewire is likely necessary before selling.

Does a rewire add value to your house?

Whilst a rewire won’t necessarily add value to your house, it will prevent buyers from leveraging faulty electrics to decrease their offer.

When considering an offer from a buyer, a survey of your property will be conducted before the exchange can take place.

If the electrics are faulty, outdated, or unsafe, it will be reflected in the survey and may result in the buyer withdrawing from the sale entirely or using a “gazundering” tactic and reducing their offer significantly.

For you, this means that even though the £5,000 spent on rewiring won’t increase the asking price by the same amount, the buyer won’t be able to reduce their offer by £10,000 to cover the costs and hassle of rewiring the property themselves.

Can you sell a house with old wiring?

It’s not shocking that you’re asking yourself if you can sell a house with outdated wiring, especially considering the costs and problems it would cause if you rewire it.

The answer is yes, you can, but it may be more difficult to find a buyer, and they may make a lower offer or reduce their offer when they understand the house needs rewiring.

To avoid this situation, there are a few things you can do when you have old wiring but don’t want to put the money and effort into rewiring your property.

Set reasonable price

If you are looking to sell your house without rewiring, you should set the asking price to be reasonable and take into account how much money a buyer will need to spend to get the property up to the required standard.

This will show buyers that the property is priced and takes into consideration the cost of rewiring.

However, rewiring a house can be a daunting prospect for potential buyers, and this may discourage them from buying your property.

We know that buyers already offer lower than the asking price, as they view it as a ‘guide‘. Unless you specify ‘offers in excess of‘, you could end up getting an offer that is 5% or more below the asking price.

But what if you need to sell now?

Sell to cash buyer

Selling a property with old wiring doesn’t have to be a hassle – there is a simple solution. Cash buyers are the ideal option as they tend to be buying properties to renovate or rent out, meaning they won’t be too concerned about the wiring.
