Lots of interesting stuff in this thread BUT making comparisons/comments in £s isn't very helpful given the volatility of energy prices - the sure-fire method is to use the consumption figure in KwH + the standing charge.
I've been tracking our consumpton since we moved to this house in February 2020 (4 bed/2 bath detached, built late 1960s, lots of insulation in the loft - not sure about the walls - gas for CH & big tank HW, electric for cooking - just 2 of us, retired, so here most of the time)
My spreadsheet presents a fairly consistent picture with reductons in consumption when we made a few changes that cost around £300 - swapped every light for LEDs, fitted Hive valves to 4 radiators to enable timed control in 2 bedrooms we don't use and 1 room that's only used in the evening, increased insulation in the loft.
I haven't finished compiling 2023 yet (waiting on latest bill from BG) but our consumptions in 2022 were : Gas 16,400 KwH, Electricity 4,700 Kwh. so about 30% more than the "cap consumptions" - I expect similar volumes for 2023.
We've been on a series of fixed rates since switching to BG (from AVRO
) in Feb 21 with quarterly "pay the whole bill by DD" - all of which have have been below the cap KwH rates. Standing charge increases have been outrageous!
