Can someone please tell me how to work out the hourly cost of running some Christmas lights , I now there must be a formula but I don't know how to work it out.
The total wattage of the lights is 5585w and the electricity costs 14.5p kwph -
5585w! That's 5 and a half bars on an electric fire. Sorry but have to know, are you asking on behalf of the City of Westminster in readiness for wiring up Oxford Street this year?
if you want a breakdown of consumption ... or just feel curious
B&Q do an energy monitor for about �10.00
you can enter the tariff ... it gives you the cost
Thanks ACtheTroll that's a good idea - the lights are connected to individual businesses and the Business Partnership refunds what ever is used but there is always a dispute, that would solve the problem.
