Best electricity supplier for tenants

When you rent, choosing your electricity supplier often feels like a puzzle: can you really switch, who pays what, and how do you avoid inheriting an overpriced tariff left by the previous occupant? Here, in plain terms, is how a Belgian tenant picks the right supplier and pays a fair price for electricity. For the full market picture, see our ranking of the best electricity suppliers.

Can a tenant freely choose their electricity supplier?

Yes — as long as the electricity contract is in your name, you choose and switch supplier freely. In Belgium the energy market is open: the contract holder — most often the tenant — needs no landlord approval to sign up with Mega, Bolt, Engie or another provider. The only exception applies to homes where electricity is included in the rent or charges: in that case the landlord holds the contract, and you cannot switch. In practice, for a rented flat with an individual meter, you are free: just check on a bill that the contract is indeed in your name.

Which is the best electricity supplier for a tenant?

For a tenant, the best supplier combines a low price, a no-commitment contract and simple sign-up. A rented home often uses little — from 1,500 to 2,500 kWh a year for a flat — and a tenant may move from one year to the next: so it's best to avoid long contracts and hidden fees. In 2026, Mega, Bolt and OCTA+ regularly rank among the cheapest offers on Belgian comparators, with variable contracts cancellable within one month. The Mega Cosy Flex offer is often quoted around €1,039/year on a standard profile, with Bolt trailing by €50-55. Against them, incumbents Engie and Luminus reassure with their service and network, but generally charge a little more.

What should you do about electricity when moving into a rental?

When moving in, the golden rule is to take the meter reading that same day. This reading — the value shown on your meter — marks the boundary between the previous occupant's consumption and yours. Note it during the inventory of fixtures, also take down the EAN code (the 18-digit number identifying your connection point), then fill in the energy takeover form with the outgoing tenant or the landlord. All that remains is to sign a contract in your name, with your move-in date as the start date. Example: you move in on 1 September; you sign up with the supplier of your choice using that date, and you only pay for what you consume from then on. Without this step, you risk paying for someone else's consumption.

Should a tenant choose a fixed or variable contract?

For a tenant, the variable contract is usually the right choice. It is generally cheaper than fixed in 2026 and, above all, it can be cancelled with a simple one-month notice, free of charge — ideal when you don't know how long you'll stay in the home. The fixed contract locks in the price per kWh for one or three years, which protects against a price surge, but it sometimes comes with a less flexible commitment period for someone who moves. The rule: go variable if you're mobile or on a short lease, and reserve fixed for settled tenants staying several years who fear a rise. In all cases, a private customer can cancel with one month's notice — a point the CREG regularly recalls.

How can you pay less for electricity in a rental?

The first lever is to compare before signing, then not to stay for years on the same tariff. Many tenants "inherit" the default supplier or sign in the rush of moving in, then forget to compare — that's often €100 to €200 lost per year. Here is how a few suppliers stack up for a small rented-home profile in 2026:

Beyond price, adjust the monthly instalment to your real consumption to avoid nasty surprises at reconciliation, and if your home has a dual-hourly meter, shift heavy uses (washing machine, tumble dryer) to off-peak hours.

How do you switch supplier during the lease?

Switching supplier during the lease is free, without any cut-off, and handled by the new supplier. You don't need to notify the old one yourself: you sign up with your chosen supplier using a recent bill (for the EAN code and your annual consumption), and they take care of cancelling with the previous one. The meter and physical network, managed by your distribution system operator — Ores, Fluvius, Resa or Sibelga depending on your municipality — do not change: electricity keeps flowing without interruption. Notice is one month. To compare the whole market before taking the plunge, rely on the official CREG, VREG or CWaPE comparator, and on our ranking of electricity suppliers.

In short: as long as the contract is in your name, you control your supplier. Take the meter reading when moving in, favour a variable contract cancellable within one month, compare at least once a year, and look at Mega, Bolt or OCTA+ for a small home. That's how a tenant pays a fair price for electricity.
