Everything you need to know about meter certification

Just like food, each electricity meter is given a ‘best before’ date when it’s manufactured. This is called a certification date which is set by the Office for Product Safety and Standards (OPSS). Once a meter has passed its certification date, we need to replace it. This ensures the energy you use is always measured accurately to the levels specified by the OPSS.

I’ve been told my meter needs replacing, what now?

You'll find a booking link in the email we sent notifying you that your meter needs replacing. Simply book your meter upgrade for a date and time that suits you - the install's a breeze; our friendly engineer will be with you for about an hour per fuel.

Why should I replace my meter?

As meters get older they may start running too fast or too slow. When this happens, the energy you’re using isn’t being measured correctly.

Do you have to replace my meter?

Yes, we’re required to do so under governmental regulation.

Why are you replacing non-smart (traditional) meters with smart ones?

Ofgem - the non-governmental regulatory body for energy supply - has specific rules around meter replacement. Their 'Open letter on Energy Suppliers’ Delivery of the Rollout and Regulatory Obligations' requires energy suppliers to take all reasonable steps to install smart meters for all new connections and replacement meters at domestic and non-domestic premises.

Traditional meters are also no longer readily available, making them increasingly difficult to get hold of.

Why would I want a smart meter?

We are installing the latest generation of smart meters, also known as SMETS2. Across the UK, smart meters are helping create a greener energy system. By allowing us to have better insight into supply and demand, we can make better use of renewable energy when it’s available at a local level. Check out what we’re doing with our Fan club!

Upgrading to smart meters can unlock big savings:

  • Earn rewards by taking part in smart trials like Saving Sessions
  • Get an extra spin on the Wheel of Fortune every month
  • Unlock smart energy insights

There’s other benefits too:

  • No more submitting meter readings, the meter does it for you.
  • It comes with an In-Home Display (or IHD for short), enabling better insights into your hourly energy usage, so you can make more informed and energy efficient decisions.
  • SMETS2 smart meters stay smart even if you do switch suppliers (but we hope you never do!)

Do I have to pay to upgrade my meter?

Getting a smart meter won’t cost you any extra, just like the installation and maintenance of traditional meters - the costs are covered in everyone's energy bills.

My meter is already past its certification date, why haven’t I been contacted?

In conjunction with the OPSS, suppliers run service testing each year where we spot check meters of various types and ages. The results of these checks mean that some meter certificates can be extended, so sometimes the certification date written on the meter when it was first manufactured/ installed might not be accurate.

If needed, we can double-check the certification date for you, and book a replacement as soon as possible if necessary.
