Your current supply is usually shown on your electricity bill as the agreed power (kVA).
Signs that you need more power
- The main switch trips when the oven, air conditioners and water heater run together.
- You are adding a heat pump, induction hob, EV charger or pool.
- You are renovating and replacing gas or oil heating with electric.
How it works, step by step
- We calculate your loads and recommend the right supply, no bigger than you need.
- We check or upgrade the fuse box and the cable from the meter.
- We issue a new installer declaration (YDE).
- You submit the application to HEDNO and pay the connection fee. We help you with the paperwork.
- HEDNO upgrades the meter or the supply.
Moving from single-phase to three-phase also needs a three-phase fuse box and new cabling to it. The HEDNO fee depends on the power you request. We tell you the full cost before we start.
