Firstly, you need to arrange with your energy company a time and date for your smart meters to be fitted. An installer replaces your traditional gas and/or electricity meters with new smart meters. The installer will offer you an in-home display which gives you information on how much energy you’re using and what that is costing you. That’s usually it!

Your smart meters will send your meter readings safely and securely to your energy company. You can track your energy usage on your in-home display, and through the website or app that your energy company uses.

If you want to find out more about the smart meter installation process, we’ll explain what’s involved right here.

Your first step is to contact your energy supplier. You can do that very simply by typing their name in the box below, we’ll take you to the right place and you can start the process. They’ll usually request you to login with your account details so ensure you have those to hand.

Your energy company will then agree a time and date for your installation appointment with you. You or someone else aged 18 will need to be present during the installation, so factor this in when agreeing the time for your appointment. At this point your energy company will let you know what to expect and if there’s anything else you need to do in preparation.

If your home’s gas and electricity are supplied by different suppliers, we suggest having your electric smart meter installed before your gas smart meter.

Your energy company may contact you in advance of the installation to confirm the details with you.

You will need to let the installer into the property. The installer should not turn up unexpectedly – they should arrive at about the time of the appointment. They should have a valid ID card – if it is not presented you can ask them to show it to you.

You don’t have to be present in the same room as the installation but you do need to be on the property.

Depending on whether you're having one or both replaced, you'll get an electricity smart meter and/or a gas smart meter. These smart meters normally go exactly where your old meters were. If they need to be fitted nearby, the installer will ask you first.

Different suppliers may install different smart meter makes and models, but rest assured that every smart meter installed as part of this national rollout must meet a common set of technical standards.

What the smart meter installer should tell you

As part of the smart meter installation the installer should:

• show you a photo ID card before they start
• explain what your smart meter system does and how to use it
• check it’s all working properly
• give you a handy guide to using it
• answer any questions you have
• tell you where you can find more help and information
• demonstrate the in-home display if you have accepted one
• provide energy efficiency advice

It usually takes approximately one hour to install each smart meter. If you’re having both an electricity and gas smart meter installed at the same time, it should take about 2 hours for the whole process. If you’re just having 1 smart meter installed, then it should take about an hour.

As part of the installation, you’ll also be offered an in-home display – a portable display screen that you can put anywhere in your home. You don’t have to have one, but it’s the easiest way to see what energy you’re using and what it’s costing you. This is provided at no extra cost.

The in-home display will show you exactly how much energy you're using in near-real time in pounds and pence, so it's easier for you to keep an eye on what you're using. With this information, you can identify the situations where you’re using a lot of energy and might want to make changes to reduce it. If you reduce your energy use, you should be able to cut your energy costs.

Yes, all installers have to pass a formal qualification and have to meet specific national standards. These standards are set out in the Smart Metering Installation Schedule. All the energy suppliers have signed up to this code, which is regulated by Ofgem, who have powers to enforce it by fining suppliers if necessary. So you can be sure the installation of your smart meter is safe.

The smart meter installation process is planned with you in mind. This includes providing important information to you before installation and ensuring that the engineers carry out the installation in a courteous and professional manner.

Suppliers regularly review and update their working practices to ensure installer and customer safety regarding COVID-19. If you are concerned at all you should speak to your supplier about this when booking your installation.

Once your smart meter is installed, your meter readings will automatically be sent to your energy supplier, meaning you will receive accurate, not estimated bills. And because all smart meters are certified by the Office for Product Safety & Standards, you can be sure your smart meter is accurate.

You will be able to control how often your smart meter takes a meter reading and how much data your smart meter sends to your energy supplier. This can range from half-hourly, daily, or in some cases, monthly meter readings.
