Everything you need to know about meter certification periods

Just like food, each electricity and gas meter is given a ‘best before’ date when it’s manufactured. In the industry it’s called a certification date, and is set by the Office for Product Safety and Standards (the 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 meters need replacing, what now?

Head to your online account and you should see a pop-up to book an installation date. Just click yes, and pick a date and time that works for you.

If there aren’t any appointments available in your area, you can register your interest in a smart meter and we’ll be in touch when there’s engineers available again.

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, which isn’t good for anyone!

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 meters 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.

Do you have to replace my meter?

Yes, we’re required to do so under governmental regulation. It is our duty to ensure customers have continuity of safe energy supply that is accurately recorded.

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 ‘New and Replacement Obligation’ (NRO) 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?

Octopus 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:

  • Get a chance to win a year's free energy every month
  • Get cheaper rates when energy's greenest with a smart tariff
  • Get an extra spin on the Wheel of Fortune every month
  • Earn money by taking part in exclusive smart energy trials (there's one coming up in the next couple of months...)

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?

There are no up front costs for the installation, smart meters, communications hub or In-Home Display. Instead, just like the installation and maintenance of today’s traditional meters, the cost is covered through everyone's energy bills.
