There are a few important things you’ll need to prepare before your smart meter installation. Firstly, make sure you know where your current gas and electricity meters are located and check that they’re easy to get to. If you think this might be an issue or you believe your current gas and electricity meters are difficult to access or locate, please let your energy supplier know well in advance.
Your supplier will have been in touch to arrange this installation. They will never turn up on your doorstep unexpectedly. When the installer arrives, they'll take all reasonable steps to keep you safe. They should present you with a valid identity card including the company name and phone number, as well as their name and photograph. You can ask to see this if the installer does not present it upfront. You’ll need to be present during the installation, which will take around an hour for your gas meter and an hour for your electricity meter, during which time your energy supply will be cut off for a short period.
Once your smart meter has been installed, the installer will talk you through how to use your new in-home display. If a gas meter is being installed, the installer will also perform a visual safety check on your gas appliances as part of the installation. It’s worth remembering that smart meters are provided at no extra cost, so you will not have to pay your smart meter installer.
BEFORE YOUR INSTALLATION
Your energy supplier will contact you beforehand to arrange a time and date for your installation. They will tell you what to expect, how long it will take and if there’s anything special you need to do before the visit. If you haven't already been offered a smart meter, you can request one from your energy supplier.
What if I have different energy suppliers for my gas and electricity?
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.
How are energy suppliers making installations safe?
The smart meter installation process is planned with the consumer in mind. This includes providing important information to the consumer before installation and ensuring that the engineers cary out the installation in a courteous and professional manner.
Also, if you or someone you care about is worried about COVID-19, please inform your energy supplier of the situation Your energy supplier could relay this message to the engineer, which could improve the installation experience. For the latest regulations surrounding COVID-19 for each nation, please refer to the links below:
Energy suppliers have implemented socially distant ways of installing the technology and safety procedures which could include:
- Installers and customers to observe social distancing
- Suppliers carrying out a risk assessment before arriving at your premise
- Wearing face coverings (or relevant PPE where this is typically required for work, including relating to the installation of smart metering)

Some advice:
• You will need to let the installer in on the day and make sure they can get access to your traditional meters. So you might need to clear out the cupboards. If you have any access issues, do let your supplier know.
• Your engineer will need to turn off your electricity and/or gas supply to complete the installation. So, ensure you have any important documents on your computer saved and switch off household alarms before the installers visit. And remember to switch everything back on afterwards.
DURING YOUR INSTALLATION
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.
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.
During the installation, the installer has to:
- 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 IHD if the customer has requested one
- provide energy efficiency advice

Don’t miss your installation appointment
Did you know, smart meter installers group appointments by location? They do this so they don’t have to travel long distances between installations, so they reduce the carbon emissions given off when they travel. Great!
Try to avoid cancelling your smart meter appointment so installers don’t have to make an extra trip to your area, increasing their carbon footprint. Don’t miss out while installers are in your area – book an appointment when you know you’re going to be available.
AFTER 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.
WILL THE PERSON WHO INSTALLS MY SMART METER BE PROPERLY QUALIFIED?
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.

FAQS
Do I need one smart meter for gas and another for electricity?
Yes, if you're a dual-fuel customer, both meters will need to be replaced. Your supplier will aim to install both meters on the same visit to make things as easy as possible. You will only need one in-home display to view both your gas and electricity usage. If your gas and electricity accounts are with different suppliers, you will have two separate smart meter installations - one from each of your suppliers.
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. We have a lot more information about smart meters and the installation process on our installation process page.
How is my personal data kept safe when I have a smart meter?
Personal information such as your name, address and bank details are not stored on your smart meter. The meters simply record your gas and electricity readings in the same way as your traditional meter. The meter readings collected can only be shared with your energy supplier to allow them to prepare an accurate bill and they cannot share this without your permission. The data is transmitted safely, using a dedicated and secure wireless network. All this information about your energy use is strongly protected.Depending on what you've agreed with your energy supplier, your smart meter will share half-hourly, daily or in some cases, monthly meter readings. You can change your preference at any point by getting in contact with your supplier directly.
If you have given them permission to do so, your energy supplier may also use this information to offer you tailored energy efficiency advice and improve the service they provide for you.
