Do I have to have a smart meter?
You don’t have to have a smart meter if you don’t want one. The government has set a target of having a smart meter in every home by the end of 2020, but you are under no legal obligation to have one installed.
However, it’s worth bearing in mind that if you refuse a smart meter, you might miss out on certain tariffs in the future that require a smart meter. This means you may not have access to the best deals and could end up paying more than you need to.
