A conto bills, why utilities settle yearly

Updated July 2026Reviewed July 2026
The short versionA conto (a-conto) means you pay an estimated monthly amount for utilities like heating, water and sometimes electricity, then settle up once a year against your actual use. A refund or a bill follows the annual reading.

What a conto means

Many Danish utilities, especially district heating (fjernvarme) and water, are billed a conto: you pay a fixed monthly estimate based on expected consumption. Once a year the provider reads your actual usage and reconciles it. Use less than estimated and you get money back; use more and you owe the difference.

Why the annual settlement matters

The annual årsopgørelse (settlement) can be a pleasant refund or an unwelcome extra bill, so do not treat the monthly a conto as your true cost. A cold winter with high heating use can mean a bill in spring. Budget for the possibility.

What is usually a conto

Typically heating and water. Electricity is often billed on actual metered use (Denmark has smart meters and a liberalised market where you choose your supplier), though some plans also use a conto. Check each bill so you know which is estimate and which is actual.

Tips

Read your meters when you move in and out so you are not charged for a previous tenant. If your usage changes (you move, work from home, have a baby), ask to adjust the monthly a conto so the annual settlement is not a shock. Utilities are often on top of rent, factor them into your budget.
