The fridge freezer - where was it located and how hot and how full - not sure if this an old wifes tail, but we keep the freezer as full as possible - often just with bread - as an empty freezer apparently uses more power
whats the power rating of the fridge freezer - then use that to work out the cost @kWh based on it being on all the time , then a reduce by a factor
it wont be on all the time, and if not there , then you are not opening or closing , so it should stay constant temp with less power
Our fridge and freezer we have in the garage , i saw an increase in usage when i switched those on
The timer control will use power not much - again it may have its wattage on
DAB Radio on standby - if its new , then the standard should be to use less than 1W on standby -
1x24x8 = 192W - so 0.192Kw - * by unit cost - say now 40p (i dont know the latest costs) , thats about 8p , just to have on standby for 8days
the router again my have a power rating - so you can work that out
the router maybe 10W ish
so that would be 80p on its own
CH controller
lets say the 6w as thats a drayton from
screwfix
so that 48p
8p+80p+48p
£1.36 = 17p a day based on 40p per KWh
fridge freezer - looking at various sites 250kWh in a year - various from F to A++
30p a day
50p a day would seem approx
you reckon 45p - but i dont know what kWh cost you are using
