I’ve been with Bulb for a year so thought I’d enter my bills into a spreadsheet and figure out my usage and whether it would make sense to switch.

I had to apply a load of fudge factors for the bills to add up.

e.g. prev estimate 96080, new estimate 96358, Energy 279 kWh @ 12.39 p/kWh £ 34.52

First of all that’s 278 kWh and 278*12.39 is £34.42 and 279*12.39 is £34.57

So where does the £34.52 come from? Is 12.39 not an accurate value and there’s a more accurate value that you round to two decimal places?

Practically every statement has similar issues and it’s almost like someone typed the figures in by hand and used a calculator. They’re only off by a few pence so it’s more annoying than anything else. Is there any explanation?

Would be good to be able to download bills in CSV format.
