Has anyone looked into MMSP? 

https://www.ofgem.gov.uk/key-term-explained/metering-and-monitoring-service-package-mmsp

I've had a quote from my supplier.  It's quite expensive at nearly £1300 but from what I can understand you get £805 back right away and another £805 back over 7 years.  I work that out as about 7.5% per year return before inflation on the £500 I don't get up front, which isn't bad for a fixed return.  It's not for the money really, but more for the ability to monitor the system.  This is the hardware and software

Any thoughts?

I was going by the data below.  It suggests that the total number approved so far is nowhere near the total available of 11255

I'll certainly check before committing as I'm definitely not paying for it myself.

I just checked with Ofgem by phone (eventually!) and the graph I linked to is correct if a little out of date.  There are only just over 4000 approvals so plenty left before the 11255 is reached.
