Hi

I am in the process of setting up my own mobile coffee and sandwich shop in Aberdeen, Scotland.  I am pretty clued up on everything, other than what is required to power my electrical equipment.  As I will be set up in the street with no direct access to power, I will need to power via a generator and will need to power the following electrical appliances;

• Coffee Machine - 2 group
• Electric Coffee Grinder
• Soup Kettle
• Fridge - 3 door
• Hot water Urn 

I am finding it difficult to establish what sort of cost this will be to power all this, and also the size of generator I may require?  Can anyone advise?

Thanks in advance for any information!

Kyle :)
