Electricity costs vary depending on your supplier, but anyway any tarrif will be cheapest on say, economy 7, maybe 4p an hour, Day rate, first x amount of units used will be say, 15p an hour, after "x" amount of units are used price will drop to maybe 10p an hour. ( A unit = 1 kilowatt) So it depends when you use the appliance. Whatever time you use it based on previously mentioned costs it will be 2/5ths of the price of one unit, as 400watt is 2/5ths of 1 kilowatt. Look on your leccy bill, will tell you what each rate is.

Well in one hour it will use 0.4Kwh. Now depending on your particular electricity supplier 1 Kwh costs anywhere between 5p and 10p I think. It should say what you pay for 1 Kwh on the top of one of your bills. Just take 2/5 of this.

Typical kwh charge is about 12p, so 400 watt heater would cost about 5p per hour.

Orite mate,
It should state on it somewhere the KW/hr rating, one unit of electricity is equal to 1 KW/hr therefore, the number of KW/Hr multiplied by the price of 1 unit of your electricity, equals the cost for 1 hour.

It depends on your unit cost per KWH. if for example its 20p then it would cost around 9pence.
