Smart Home Wiring New Builds

Smart homes are on the rise in the country, with around 2.22 million smart homes in the UK at the moment and projections for this figure to rise considerably over the next couple of years.

While smart tech enthusiasts are converting their existing homes into smart homes, there are now several new builds with smart home wiring pre-installed.

The UK’s first new-build smart home was constructed in 2018 with a fully integrated Apple home system. Since then, the numbers have risen significantly with many new builds going the ‘smart’ way.

If you are building a new home and have the opportunity to integrate smart home technology into the design in order to achieve complete automation, we say go for it!

Imagine walking through the front door and the lights automatically turning on or the thermostat adjusting itself according to your preference and the ambient temperature. Also, getting a notification every time someone steps foot on your property or playing your favourite music in different parts of the house.

Sounds good, doesn’t it? Well, this is just the beginning. Smart homes allow you to control appliances, lighting, heating, and entertainment systems using a smartphone or computer from anywhere in the world.

They may also include home security systems such as burglar alarms, CCTV cameras, security lighting, and access control systems.

The first step towards building a new smart home involves laying out the wiring and electrical work to accommodate the technology.

Read on to find out all about smart home wiring for new builds, why it is necessary, and the important factors to consider:


Smart home design could alter the way we think about technology in our homes. A smart home system is fully automated and knows what to do and when with limited input from the homeowners once the schedules and preferences have been set.

By installing the right smart home infrastructure in your new build, you can create a home that can be controlled from an internet-connected central app, including the lighting, music, heating, security, and much more.

While quite a few standalone smart home devices may become obsolete in a matter of time, integrated smart home systems last for much longer and can adapt to your needs as they change, with support from your professional installer, of course.

Another great benefit of a smart home is that it enables you to be as energy-efficient as possible. It helps cut down energy use, which reduces costs both in terms of financial savings and the negative impact energy overuse and misuse have on the environment.

You may even consider installing solar panels to your smart home, or the wiring to add them later on for clean and green energy. Additionally, you can install EV charging points to reduce your dependence on fossil fuels such as oil and gas.

Here are all the reasons why every new build must be a smart home:

  • Home automation features – robust and up-to-date smart wiring will allow you to enjoy great home automation features with efficient operation and incredible cost savings.
  • Boost your home’s value – it won’t be long before smart wiring will be a hot feature that buyers will look for when investing in a property. Since it allows you to future-proof your home, you can benefit from the latest trends and innovations to hit the market.
  • Saving energy and money – built in a way to conserve energy in the best way possible, a smart home has the potential for great energy and cost savings.
  • Make your home life simpler – you can simplify regular household tasks and make your life simpler and more convenient by letting the system take care of mundane tasks while you focus on other important matters.
  • Remotely control your home – the ability to remotely control your home and the components and devices in it is like no other. Especially useful for when you are away from home, this feature makes you feel like you’re still there and in control of everything.
  • Safety and security – In addition to offering savings and convenience, smart homes offer added security in the form of burglar alarms, CCTV cameras, access control systems, smart locks, and security lights, all of which you can remotely access and control via your smartphones, tablets, and laptops.


From lighting to thermostats and smart speakers, there are several aspects of a new build smart home. Here are some of the most common devices and systems that make a smart home ‘smart’:

Good speed internet

A reliable internet connection is essential since it is what connects the various parts of a smart home and allows you to remotely access and control it from absolutely anywhere in the world.

Smart lights

Smart lights can be controlled via your smartphone, and you can also set schedules and timers for when you want them to be turned on and off.

Not only can you turn the lights on and off with a simple tap on your phone but also adjust their colour and brightness according to your requirements.

All smart lights are LED (Light Emitting Diodes) lights that consume far less energy than incandescent and fluorescent bulbs and can significantly lower your energy bill.

Smart speakers

Smart speakers take accessibility and convenience to a whole new level by allowing you to speak commands to your smart gadgets and appliances.

Instead of having to take out your phone to control your smart home devices, you can simply speak to them to take the required action. You may also ask them questions such as updates for the weather or to find a certain recipe while you’re cooking.

Smart plugs and switches

Smart plugs and switches are the easiest and most inexpensive way to may any appliance in your home a smart appliance.

For instance, if you connect a lamp to a smart switch and plug it into the wall, you’ll be able to control the lamp from your smartphone. You can also set schedules for the plugs to turn on and off, and also link them to other smart devices.

Smart home security cameras

Smart home security cameras allow you to keep an eye on your property and know who’s coming in and going out, all from your phone, tablet, or laptop.

You may choose from a wide range of indoor and outdoor CCTV cameras such as bullet cameras, dome cameras, PTZ (pan/tilt/zoom) cameras, and wireless cameras.

The best smart cameras have features such as motion sensors, night vision, high resolution, weather resistance, a wide field of view, professional monitoring, and the ability to be linked to other smart home devices.

Video doorbells

Video doorbells are another great home security surveillance option that is extremely useful since they send a live video feed to your smartphone or tablet every time someone rings your doorbell.

Not only do they offer additional security, but also act as an intercom and are extremely helpful for individuals with mobility issues who have trouble getting to the door to check who rang their doorbell.

Smart thermostats

Smart thermostats give you the ultimate level of control over the temperature of your house, regardless of where you are in the world.

You can easily control the temperature of your home via your smartphone, tablet, or laptop, and link it to other smart home devices such as motion sensors, lights, and blinds.

In addition to providing great convenience, smart heating controls also help you save money in the long run by reducing your heating and cooling costs by automatically turning off or lowering down the settings when you are not at home.

They come equipped with motion sensors to pick up on when people are around and when they are not.

Many systems also have a learning feature that, in combination with the motion sensors, can be trained to know when people are present and when the heating needs to be turned on or off.

Smart home hubs

Smart home hubs allow you to connect several smart home devices so that they can be controlled from a centralised location.

For instance, you can use it to turn on the lights, adjust the temperature on your smart heating controls, start playing music, and close the blinds when you enter through the front door.

Other smart home devices include:

  • Smoke detectors: send alerts to your smartphone if the system detects smoke or fire in the house.
  • Burglar alarms: work using sensors that detect intrusions and break-ins and send notifications on your phone every time the alarm is triggered.
  • Garage door openers: control the garage door through your phone and receive alerts every time it gets opened.
  • Smart sprinklers: automatically water your garden on certain days and times depending on the weather and temperature.
  • Universal remote: control a host of entertainment devices (up to 15), such as the television and stereo, all from one device.


Smart home wiring for new builds is less expensive than retrofitting a home since you won’t have to pay extra for opening up the existing walls to accommodate the new wiring.

The beauty of today’s smart home technology is that it is all mostly wire-free. Most of the time, all you require is a smartphone and a good Wi-Fi router to benefit from the power of interconnected and remotely accessible devices.

There are still, however, a few key components that need to be hardwired – depending on whether you wish to go 100% smart or pick and choose – so that they can communicate with the ‘not smart’ appliances, such as the connected heating and air conditioning system.

This is because not all devices controlled by your smart home are smart themselves, such as the air conditioner and refrigerator, and may be ‘dumb’ with manual controls.

With smart home wiring, they can be connected to smart controllers to make them a part of the smart home environment.

Some common home components and appliances that work best when wired include:

  • Smart thermostats – as long as your HVAC system is connected to a smart thermostat that is wirelessly connected to a smart hub, it doesn’t matter if the system itself is smart or not.
  • Smart light switches – just as smart thermostats that control the HVAC systems, smart light switches control dumb lights and fixtures. Since smart light bulbs come in certain sizes and can’t be fitted in many fixtures, it may be a good idea to install regular LEDs and control them through wired smart switches.
  • Smart outlets – smart outlets transform any device into a smart device by simply plugging it in. Since they control the flow of electricity into the devices, they need to be hardwired into the system.
  • Smart smoke alarms – since smoke and fire alarms are extremely critical to safety, they must have a dual power connection, both wired and wireless, along with backup batteries for emergencies.
  • Smart doorbells – the same way that you can’t rely on a single connection alone for smoke and fire alarms, smart doorbells also cannot be relied solely on batteries and need to be wired into the house for uninterrupted safety and security.


By deciding to install smart wiring into your new build, you will open yourself to endless opportunities when it comes to comfort, convenience, and cost savings.

Although wireless connectivity is all the rage these days and is faster than ever, your home still requires a solid network of wiring for higher bandwidth, better internet security, and much more.

In a world that is shifting towards everything wireless, talking about the importance of wiring and cabling may seem a bit outdated but, in reality, wiring is and will remain an important part of both smart and ‘unsmart’ homes.

You can think of wiring as a home’s digital backbone that supports all of the different technologies in your home by delivering data, audio/video signals, security, and communication to a wide range of devices with unparalleled accuracy, speed, and reliability.

Smart homes are heavily dependent on a good internet connection, and while high-performance wireless networks (Wi-Fi) are capable of providing all sorts of signals throughout the home, there are certain limitations and challenges with relying too heavily and solely on this approach.

Proper wiring also makes way for a more secure network that is less susceptible to cyber-attacks and hacking.

This is a real and very prominent concern facing many smart home owners, of the devices in their homes “listening” to their conversation via hacking.

Cabling mitigates this risk by reducing signal interference and security threats that are a common problem with wireless Wi-Fi networks. Of course, this issue can be resolved by practising better security and being careful with how you use the system and its components.

Lastly, one of the biggest benefits of installing network cables throughout the house is the burden it takes off the Wi-Fi network.

As more devices get connected to the wired network, the home’s Wi-Fi connection becomes more available to devices that depend on a wireless connection, such as your smartphones and tablets.

Also, devices such as smart lights and thermostats that require only occasional access to the internet can use the wireless connection, whereas other systems such as security cameras, video doorbells, and smart televisions can work on the wired network for uninterrupted internet signals.
