Electricity connection cost and charges
The cost of a new electricity connection is set by the work needed at your site. Each distribution network operator (DNO) publishes its own charging methodology, so the same job can cost differently in different parts of the country.
What affects the price
- Capacity: the more power you need (kVA), the larger the cable and equipment.
- Distance: a longer cable run from the nearest suitable network costs more.
- Groundwork: digging through roads, pavements or rock costs more than open ground, and reinstatement is charged.
- Network work: some jobs need a new substation or reinforcement of the existing network.
- Phases: three phase supplies cost more than single phase.
- Number of plots: a development shares some costs across plots.
Who does the work
Some of the work (cable laying and trenching) is open to competition, so an independent connection provider can price it. The rest, including design approval, stays with the DNO. Compare the full total from each, not just one line.
Cost to connect electricity to a new house
For a single new house, the main questions are how far the plot is from the network and how much power you need. A site next to an existing cable is usually far cheaper than one that needs a long new route.

Frequently asked questions
How much does a new electricity connection cost?
It depends on capacity, distance to the network, groundwork and any network reinforcement. Enter your address and power need for a budget price from your DNO's published charges.
Why do electricity connection charges vary so much?
Each site is different. A short cable run in open ground costs far less than a long route under a road or one that needs a new substation.
Can I reduce the cost of a new electricity connection?
Sometimes. You can compare an ICP quote with the DNO's, ask whether some groundwork can be done by your own contractor, and avoid asking for more capacity than you need.
