Why energy prices in Belgium keep changing
Energy suppliers adjust their tariffs regularly — wholesale prices move, and that feeds through into both fixed and variable contracts. CREG, Belgium's federal electricity and gas regulator, regularly publishes updated tariffs for every supplier: a comparison you did a year ago, or read somewhere online, doesn't necessarily reflect today's prices.
Generic comparison tools vs. your real smart meter data
Most comparison tools work from a typical usage profile, not yours. If you have a smart meter (digital meter), your actual consumption is measured down to the quarter-hour — a far more precise basis than a generic estimate, especially for evaluating a dynamic contract.
- Every supplier's current tariffs, straight from the latest CREG publication.
- Your own, current usage pattern — not last year's, unless you upload that yourself.
- For a dynamic contract: the real, historical day-ahead prices for the chosen period, not an estimate.
One comparison isn't enough: how to keep your energy contract competitive
Because tariffs change, a comparison that favours you today might not in six months. A yearly subscription lets you compare as often as you like without buying a new credit each time — useful if you want to keep checking whether switching still pays off.
Always based on your own numbers
Whenever you compare: the result is calculated using your own measured quarter-hourly usage against the tariffs in effect at that moment — never a dated list, never a guess.
