How to find out if you have a half hourly meter

So how do you go about identifying a half hour meter and how do you know if you have a half hour electricity meter?

It’s actually quite straight forward, and all you will need to find this out is a recent copy of your electricity bill.  It doesn’t have to be the latest half hourly electricity invoice, any recent bill will do.  Then on your invoice you need to find your meter point reference number or MPAN for short.  This is a numerical version of your tariff and supply point details, and is unique to your supply.

This is how half hourly suppliers’ mange to identify your supply details and price up your electricity requirements.  The MPAN is a series of numbers, normally in a box and usually identified with a large S at the front.  In nearly all cases theses number are split up into two lines with 8 numbers at the top and 13 numbers at the bottom.

The bottom line is the part that’s unique to your half hour supply, and this is how your supply details are used by a supplier.  It’s actually the top part that allows you to identify if you have a half hourly meter.

And you need to look at the first two digits of this top line, if these two digits are both zeros “00” then you have a half hourly supplied meter, and you will need to speak to a specialist half hourly supplier such as Catalyst in order to obtain comparative quotes.

If these two numbers are not “00” then it will be one of these – “03,04,05,06,07,08” which indicate that you have a non half hourly meter or NHH supply.  In some cases if you have a very small supply then it may fall into a domestic meter profile which is indicated as a “01 or 02” on your bills.

The thing to note here is that if your not sure if you have a half hourly supplied meter, then you can always just ring your supplier and ask them.  Some suppliers deliberately don’t show the top line on invoices any more for exactly that reason.  As it offers a reason for you to engage with them, and gives them the ability to up sell additional services.

Half Hourly MOP Contracts

Now we have helped you in identifying a Half Hour Meter, we also need to let you know that for each half hourly supplied electricty meter, you also require a meter operator contract or MOP for short. Those companies with Half Hourly (00 Profile) meters installed are obliged to have a MOP contract in place.  The MOP contract provides covers the installation, operation and management of the half-hourly electricity meter.

A MOP contract is required by law for businesses with half-hourly meters with 100kW plus consumption and if you don’t agree to one then your electricity supplier will sometimes appoint one on your behalf, but normally at a higher cost point.

We can also provide quotes for your MOP contracts, and ensure that you have the correct version in place.
