Smart meter installations

We have installed over 2 million smart meters across the UK. Our guide will help you prepare for your smart meter installation and understand what to expect on the day.

How to prepare for your smart meter installation

1: Make sure you're in

Someone who is at least 18 years of age must be there during the installation. This takes about an hour for each meter.

2: Get access to your meter

We need to be able to get to your meters easily. Make sure you have the key to access it if it's located in a cupboard or in a locked room.

3: Keep your pets away

Make sure your pets are in another room during the installation so they won't be disturbed.

What to expect on the day of your smart meter installation


  • We'll call you before your appointment to check that it's still safe for our installer to enter your home
  • If you're self-isolating we won't be able to carry out your appointment. Please let us know as soon as possible if this is the case.
  • We’ll ask you to check that our installer will be able to easily access your meters. Read below for tips on how to prepare for the installation.


The engineer will need to come into your home to complete safety checks, even if your meter is outside. If anyone in your home develops coronavirus symptoms before, or on the day of the appointment, please reschedule for a later date.

It takes about an hour to install each meter, and your power and gas will each need to be switched off for around 30 minutes. But in some circumstances, it could take longer.

Once your smart meter is installed

After installing your smart meter, our installer will get you connected to your new in-home display (IHD). They'll be able to give you some useful advice on how to get the best out of your new smart meter and in-home display.

We also have helpful guides you can use.
