Best electricity supplier for the self-employed

When you're self-employed and work from your living room or a small office, one question keeps coming up: do you need a "business" electricity contract, and which one should you pick? The answer often comes down to one thing: the meter. Here's how, without jargon, to pay a fair price for your electricity and deduct your expenses correctly. For the full market picture, see our ranking of the best electricity suppliers.

Does a self-employed person need a business electricity contract?

No, not automatically. If you work from home on the household meter — the case for most freelancers, consultants and liberal professions — you can stay on a standard residential contract. Being self-employed doesn't force you onto a "business" offer: it's the nature of the connection and the premises that decide. In practice, as long as you share the meter with your private use, a residential contract is perfectly legitimate, and you then deduct the professional share on your tax return. A business contract only becomes necessary for premises dedicated to the activity, a workshop or shop with its own meter, or a high connection capacity.

Residential or business: which contract is cheaper for the self-employed?

In the vast majority of cases, the residential contract is more advantageous. The main reason is fiscal: residential electricity enjoys a 6% VAT rate in Belgium, whereas business contracts have returned to 21% VAT since 1 July 2023. For a self-employed person at home, keeping the residential contract means paying 6% VAT on the whole bill, then deducting the professional fraction — instead of paying 21% up front. As a benchmark, CREG placed the energy component in mid-2026 between €0.106 and €0.171/kWh depending on the offer, and the regulated tariff for small businesses at around €0.158/kWh excluding VAT. The business contract only regains the edge if your activity consumes a lot and you recover all the VAT on a strictly professional meter.

Which electricity supplier should you choose when working from home?

For a self-employed person on a residential meter, the best offers are the same as for a cost-conscious household: Mega and Bolt at the top. In mid-2026, Mega Cosy Flex runs at around €1,027 per year for 3,500 kWh, regularly making it the cheapest offer on the Belgian market; Bolt follows within about fifty euros, with a local green positioning and a polished app appreciated by remote workers. In short, your activity changes nothing about the energy price: you look for the best price/service ratio like any household. Before signing, always check your specific case on the official comparator of CREG, VREG or CWaPE depending on your region.

Which suppliers offer the best deals for the self-employed and SMEs?

As soon as you have dedicated premises, heavy usage or a company, the historic suppliers become relevant. Luminus, Engie and TotalEnergies have structured business offers, with multi-site management, longer fixed contracts and a dedicated contact; on an average profile, Luminus is often 7 to 10% cheaper than Engie. OCTA+, a historic Belgian B2B player, combines energy and fuel cards — handy for a self-employed person on the move. The table below sums up who each supplier is for, depending on your profile.

How do you deduct your electricity bill as a self-employed person?

You deduct the professional share in proportion to the surface used for your activity. If your office takes up 10% of the home, you deduct about 10% of your electricity, heating and water costs; the Belgian tax authorities generally accept a deduction of up to around 15% for such mixed expenses, as social insurance funds like Xerius or Liantis point out. On a residential contract at 6%, this deduction is made on personal income tax, with no VAT recovery. If you opt for a business contract at 21%, you can instead recover the VAT on the professional fraction only: a 40% pro / 60% private use gives a right to 40% recovery. The right habit: keep a clear bill showing your EAN code and annual consumption, essential both for comparing and for justifying the deduction.

How do you switch supplier without risk for your activity?

Switching is free, without any cut-off and entirely handled by the new supplier. You subscribe with a recent bill on hand — for your EAN code and annual consumption — and the new supplier notifies the old one and organises the handover. The physical grid, managed by your distribution operator (Ores, Fluvius, Resa or Sibelga depending on your municipality), doesn't move: your activity is never interrupted. Residential contracts, including for a self-employed person at home, can be cancelled at any time with one month's notice, free of charge. In short, a self-employed person working from home almost always benefits from a good, well-deducted residential contract; save the business offer for dedicated premises or heavy usage.
