Dutch consumers overpay on heavy electricity connections

More than 300,000 Dutch households and small businesses maintain unnecessarily heavy electricity connections, according to regulator Autoriteit Consument & Markt.

Why it matters:

Consumers frequently waste thousands of euros each year on standing fees because high-capacity connections cost substantially more than standard residential links.

By the numbers:

• Standard 3x25 Ampere setups handle up to 15,000 kilowatt-hours and cost an average of €360 per year in 2026.
• Upgraded 3x35 Ampere links average €1,800 yearly, whereas the largest 3x80 Ampere connections reach up to €4,500 annually.
• Downsizing an electricity connection requires a one-time adjustment fee of roughly €300.

Between the lines:

The Autoriteit Consument & Markt (ACM) noted that a typical four-person household in a terraced house uses only about 3,500 kilowatt-hours annually. Heavy connections are solely needed when running intense equipment concurrently, such as saunas, swimming pools, or heated ponds, though peaks can often be managed by staggering appliance use or charging electric cars more slowly.

What to watch:

The regulator urged residents to verify their connection tier on their annual energy invoice and consult their netbeheerder (regional grid operator). However, ACM cautioned that consumers should think carefully before downgrading, as grid congestion means anyone wanting to upgrade again later often ends up placed on a waiting list.
