If I wanted 3 phase put in a house whats the likely bill from the DNO. Reason being a customer wants his entire house fitted with AC, best method is to use a VRF system but there all 3 phase.
main factor is likely to be distance from an available 3ph supply to tap into. The cable out under the street is likely to be 3 phase, unless its out in the sticks.
