I've just received a huge bill from the Gas supplier (£600 for one quarter!), so I decided to try investigate how much Gas I *should* be using, but I can't find it anywhere.
Yes, the current reading is estimated, but the last reading was from an actual meter-reading. I can't actually climb up high enough to read the meter myself, but from what I can vaguely make out, the reading looks way higher than they've even estimated.
I've searched online for hours and called the Gas board, but can't find any way of calculating a likely least / most scenario of how much I should be paying, or how many units I should be using.
It's a 1 bedroomed flat. Single glazing throughout, high ceilings. 5 radiators in the flat. Three of those are double, and one is permanently switched off, so that's 7 radiators, all of which are small. (not the huge 6foot versions). I have a combi boiler (Baxi - don't know the model.). I leave the temperature in the flat at 20degrees during the day when I'm out and whack it up to about 25-30 when I'm in. Any lower than 20 during the day, and the flat doesn't warm up at all by the time I go to bed. (I have Raynaud's
so I need to keep a comfortable temperature). I don't have any other Gas appliances - it's just for central heating and warming up water.
Is 20-30 degrees above average for heating temperature? What temperature do others keep their heating at? Is there any way I can calculate how many units / kwh I would be using in this scenario? I'm looking for something like "The least you're likely to pay is £x and the absolute most you're likely to pay would be £x type of scenario.
(I know that the bill is most likely wrong, and I do have someone coming to read the meter next week. I'm also going to get some step-ladders and read the meter every day for a week to work out my consumption. But I'm still curious how to calculate this.)
Can anyone help me here? I swear, if I find out how to calculate this, I'll set up a website so others can do the same!
