800M 32mm SWA - could this cause increased electricity bills due to voltage loss

Hi all,


Our electricity usage is very high (6,000 KWH annually) but we dont have any electricity heating or anything that should be chewing up that much electricity.


I'm looking for reasons why the usage is so high.


Our meter is actually sited on a neighbouring property and then a 35mm2 2 core SWA cable runs approx 800 meters to an Ashley Eddison transformer that regulates the voltage and amperage.


Could the length of the cable, the associated voltage drop and then the transformer usage contribute significantly to the electricity usage..?


Thanks and my apologies for any inaccuracies and ignorance!

    Yes an excessively long or undersized cable can add to electricity bills, though usually the increase is modest.

    If the voltage at the appliance is lower than normal then it might either work less efectively and thereby require longer hours of use to achieve the desired result, or it might draw a greater current.


    As regards the transformer, more detail is needed, idealy a photo of the unit and a close up photo of the rating plate. Some such transformers waste significant energy even when not loaded.


    800 meters of 35 mm cable sounds too long to supply a home unless the load is improbably small. It might be worth having a larger cable installed, but we need more details to give proper advice.
