Fuse energy

Subsequent to that I got an email from Fuse apologising for the confusion and confirming that they now have the correct information and offering me a credit to my account if I proceed with the swap.

It's good to see them acknowledging their mistakes.

I really pleased that Fuse have sorted themselves and you out.

But I still can't find any evidence that 0000 is a valid SSC ID. Anyone else care to share theirs (the four-digit number in the centre of the top line of the MPAN)?

Thanks for the ping. I'm as much in the dark as everyone else, but the changes to the MPAN 'S' panel format following the migration to MHHS are pretty well documented. It doesn't help, though, that the monumental Elexon database of Market Domain Data (MDD) is being reorganized, with much of the stuff affecting ordinary consumers being transferred to the REC. The new database is called Industry Standing Data (ISD). This document gives the basics: CHANGES TO SUPPLY NUMBER FORMAT FOR MHHS.

Some salient points as I understand the situation:

1. The Profile Code - historically 02 for 'restricted' supplies, like Economy 7 - is now either 02 as before or 00 for everyone else
2. The MTC is disappearing, to be replaced by the SSC - much more user-friendly. It only really matters for restricted supplies. The link leads to a page with more links to FAQs for those eager to learn.
3. LLFCs are being replaced by DUoS codes. Consumers don't normally have to bother about these - a big LLFC probably meant the supply point was a long way away from the distribution network, with associated higher losses and thus higher costs for the supplier. The complex DUoS codes probably take more than just distance from a substation into account, giving a more accurate measure of distribution costs for the DNO and supplier. I haven't looked into this at all, so I'm guessing.
4. The MPAN's bottom line - two-digit DNO identifier, eight-digit unique supply identifier and three check digits at the end - stays as it is.

Perhaps someone who knows what he's talking about will come along to clarify.

@rubble2's 'binary' top line looks to be quite normal in this brave new MHHS world. It wouldn't look like that if the DUoS code were something like A12Z.

It's 01 for me.

Perhaps, but I found a workbook with a sheet called "SSC TPR unit rate lookup" and the lowest SSC listed is 0003; there isn't a 0000.

@Reed_Richards

The changes are still in progress, and they won't be complete for at least another year (it's supposed to be finished by May 2027, but this sort of deadline has a habit of slipping). 00 is the new 01, and an unrestricted supply (like SSC 0393) doesn't need an SSC, which dictates how restrictions are applied - like 'every day 07:00-00:00' for an E7 offpeak supply. Don't worry about it!

The top line of my MPAN used to be 1 - 900 - 180

Then it changed to: 01 - 0393 - 100

More recently: 01 - 0393 - 180

My concern is that if some of these numbers are provisional and different suppliers are at different stages through the transition, will this cause confusion and delay when changing suppliers? In this instance, it looks as if that's what happened; Fuse were initially confused and there was a delay, although the confusion was then resolved.

Ildhund

OK, so your MPAN now shows the SSC instead of the MTC. No problem there. The LLFC seems to be in flux, but the number in your MPAN is now probably the new DUoS code. Your concern is understandable - we know just how infuriating it can be when suppliers have different ways of assessing things, but I don't think there's anything you can do about it - so cross bridges when you get to them!

The transition to MHHS is the biggest change in a generation to the settlement process (how generators charge suppliers for the electricity they sell to consumers), so there are bound to be hiccups along the way.

Mine is 0000 too. It was different in January this year so changed recently.

Reed_Richards

Are you with Octopus, @t0rt0ise? I suspect 0000 is a placeholder meaning "to be determined" (that's what Google's AI thinks). There is a list in this document https://www.engie.co.uk/wp-content/uploads/2024/12/TPR_Reference_sheet_2022.pdf but it starts at 0003

Yes I'm with Octopus.
