I’m retired, so my schedule does not change with the season.  I have the same week on week activities that take me out of the house, summer or winter and the rest of the time I sit at home in front of TV or computer.

So my Computer/TV/Washing Machine/Fridge/Cooker sees the same usage every month.

All that is different is that I have 2 room lamps which will be on for perhaps 5 hours longer in Winter than Summer.  Both these lamps have 5W LEDs in them so that equates to 1.5 kWh per month.  With my normal total usage being around 150 kWh per month, the extra caused by these lights is 1%, so statistically irrelevant.

I agree that my usage does not match the norm here, but my complaint was based upon my not being a new customer, OVO had 3 years of previous readings to check this usage.  They did not do so.  They simply ignored my complaint and did not reply.

I have a low tolerance of poor service. You don’t get a second chance.  Such a shame really, as their online account access was really rather good.

Me too.

Your FAC is based on ‘previous readings’. A customer who has three years’ worth of data from the same meter should have an FAC which accurately matches the actual consumption. This might not be the case for a new customer or a new meter until some months have passed.

My FAC changes weekly, so I get a new figure each Sunday morning. Knowing pretty well where the FAC comes from, I can predict on Friday what I’ll see on Sunday, within a few Wh. Here are December’s results:
  

Annual advance: difference between meter readings
on the same date this year and last
Grey crosses appear on Friday. Red crosses drop in on the following Sunday.

This shows that (a) we can work out where the FAC comes from, and (b) we can predict how it will change pretty accurately.
