Please help! We have moved to a house with a three phase electric supply - although two don't have fuses in. We are extending the house so moving the electrical supply three metres to a new wall - I have two quotes from UK Power Networks. One to move the existing three phase supply (more expensive) and one to downgrade it to a single phase supply and move it (cheaper). Am I best to keep three phase or move to the single? Our house is going to be a large family house but we are not a small holding or farm. Although in the future who knows what we might do - we are in an acre plot but most of it is outside of the village envelope so we can't build permanent structures on it. We also plan to install solar so generate our own supply...... Thanks in advance!
