We had a visit this week from an engineer from Northern Power Grid to look at the solution (or solutions) to the supply of 3 phase electricity to the property. It turns out to be easier than we thought.
The pole that is carrying the current single phase supply is also a 3 phase supply too. Now the engineer has pointed it out, I can see the transformer on a pole in one of the fields across the valley. It is this that is providing the 3 phase supply.
He now has enough information to provide us with a quote. This is the final piece of the jigsaw before we can place the order for the ground source heat pump – there was little point in installing one if it was going to cost £10K to install a 3 phase supply.
As it turns out, it looks as if the 3 phase supply, and the alterations to the single phase supply, (assuming that we dig the trenches) is around £2K. But we will have to wait for official confirmation.
It is cheaper and makes more sense for us to dig the trenches as we will have a machine on site to dig the foundations for the extension as part of Phase 2.
