i have a oil burning furnace that costs a small fortune . over $500.00 to fill half the tank up.
Your furnace doesn’t burn crude oil. It burns either #2 fuel oil or kerosene. If the tank is outside you probably use kerosene because #2 will gel at cold temperatures. If natural gas is available it is usually the least expensive way to heat. To reduce the cost of heating with oil, have the burner serviced once a year. Oil burners are at their most efficient when cleaned and serviced, then they start losing efficiency immediately. Once a gas burner is set up for maximum efficiency it doesn’t lose that efficiency. To figure out the costs of heating with different fuels use this simple formula: BTUs per gallon divided by price per gallon times efficiency of the heating system. This gives you the number of BTUs that you get from each dollar.
I have googled enough 
I would guess that getting your electricity from the local grid and best priced supplier will be cheaper for a 415v supply. Depending how large a supply you want you could be charged 1 or 2 pence a unit cheaper than domestic prices (or as much as half if its a really huge supply you need). Cheaper becasue of economy of scale for the generators – they can produce electricity lots cheaper than you.
Generators might be cheaper to run if you can find a cheap source of fuel for them and use the generator over many years, 20 or so.
Answerer above had a good point, why not get a kiln that is heated by the fuel directly rather than electricity? Could be cheaper depending on the fuel of course
water and gas ,there is only one choice as for electricity you have a choice but I have always used the company that repairs the lines therefore prompt service in case of a problem is guaranteed
