Electricity connection for a new build or self build
If you are building a new house or a small development you need a new electricity connection before you can have power on site and in the finished building. It is worth starting early, because the design and any network work can take time.
When to apply
Apply as soon as you know the plot layout and the power you need, ideally before groundworks start. Many self builders also need a temporary builders' supply, which is arranged separately.
What to prepare
- A site plan showing the plot and any nearby buildings
- Expected load. Heat pumps, EV chargers and electric cooking raise the demand
- Whether the site has existing underground cables, poles or a nearby substation
- The date power is needed
What affects the cost
Distance to the network, the capacity requested, the groundwork and any reinforcement. See the cost guide for more.
DNO or ICP
You can ask the DNO for a quote, or an independent connection provider for part of the work. Developers often compare both.
Frequently asked questions
How do I get an electricity connection for a new build?
Apply to your local DNO with the site plan and expected load, or ask an ICP to quote for part of the work.
How much does a self build electricity connection cost?
It depends on the distance to the network, the power you need and the groundwork. A budget price from your DNO's charges gives a starting point.
Do I need a builders' supply as well?
Often yes. A temporary supply for construction is arranged separately from the permanent connection.
