It was on for about 14 hours and in that time the thermostat would be cycling on and off, so it would actually be using power for about half of that time, appx. 7 hours. IF the iron is a typical 1200 watt model it would consume about 7 x 1.2 kwh @ about 12p per unit, so the cost would be about £1.00. (7 x 1.2 x 0.12 = 1.00)

It depends on the heat setting, the location of the iron with regards to conduction and airflow and the surrounding temperature.
It is a lot less than you might think because when the iron is hot the thermostat will cut out the power and will only switch back on occasionally to maintain the temperature.
Or you can guess. I'd say that it would average out to about 100W.
If you don't want to guess then place the iron in the same location and setting. Switch it on and let it get to a steady state. Watch the lamp. Time how long it stays on and how long it stays off. This will give you the on to off ratio. Then use the rating plate wattage value of the iron and reduce it by the ratio that you found.

Most Irons use 1500 w per hr x 14 hrs you would have to find out how much your utility company charges for each kwh.

Also what others wrote about the thermostat and possible motion sensor would apply. So it would be less than the max power requirement

All you have to do is less ironing for the next month and you will actually save money even though you did leave your iron on all day.
Try ironing less, like things that really don't need pressing and you will be amazed over a three month period just what you have saved on your electricity bill. You will recoupe your lossed £2.55 ($3.75) in less than six weeks.
Turn It Off and Turn Your Planet ON.

An iron is between 1 and 2 Kw
unless you had it on full you will probably have used around 1 kw for every hour - say 15p per hour it was on

A fair bit, you can work it out you have to know how many watts the Iron is, your house didnt burn down then??

not much as £2.50, as the heat would only come on when the thermostat has cooled down i would guess less than a quid,
dont do it again theres a good lad and get a woman to do it .

most irons have a cut out on them if you don't pick them up in a little while they turn themselves off but if yours hasn't its not cost you hardly anything so don't panic i know electric company's are robbing us blind at the moment but irons don't cost nothing hardly to use

If your iron is 1.5kW..=1500W. Time = 14 hours..Energy used =1.5 x 14kWh=21kWh
if 1kWh (1unit) costs on average 8p then it would have cost you
£1.68....no need to panic
