How to find a reliable tradesperson in Belgium? The complete 2026 guide
Wildly inflated quotes, shoddy work, contractors who vanish after the deposit… Here's how to avoid the pitfalls and find a trustworthy professional for your home improvements in Belgium.
Exploding quotes, abandoned projects, deposits pocketed with no follow-up… Finding a reliable tradesperson in Belgium remains, for many homeowners, a genuine minefield. Yet the right methods exist to protect yourself and find the right professional from the very first try.
This guide covers everything you need to know before entrusting your works — large or small — to a tradesperson.
Why is finding a trustworthy tradesperson so difficult?
The construction and renovation sector in Belgium attracts both serious professionals and less scrupulous operators. Several factors explain the situation:
Market opacity. Unlike other industries, there is no easily searchable public register listing all certified tradespeople with verified references and client reviews.
High demand. Good tradespeople are often overbooked. Faced with a full order book, some accept more jobs than they can handle properly.
Undeclared work. The temptation of "cash with no invoice" strips the client of any legal protection if something goes wrong. A tradesperson who refuses to invoice is not covered by professional liability insurance — and neither are you.
Organised scams. Some "tradespeople" actively canvass door-to-door or on social media with very low quotes, collect a deposit and disappear.
The good news: knowing what to check is enough to rule out 90% of bad candidates.
The essential criteria for choosing a trustworthy tradesperson
The enterprise number (KBO/BCE)
In Belgium, every tradesperson carrying out a commercial activity must be registered with the Crossroads Bank for Enterprises (KBO/BCE). This number, starting with 0 or 1, is your first line of defence.
Check it for free at kbopub.economie.fgov.be. A recently created business (a few weeks old) or a struck-off one should raise a red flag.
Professional liability insurance
This is non-negotiable. A serious tradesperson holds public liability insurance covering damage to your property during the works. Always ask for a certificate of insurance before signing anything.
For certain regulated trades such as electrical work or heating systems, specific licences are also mandatory.
References and client reviews
Personal recommendations remain the best filter. Ask for at least two or three references from recent, similar jobs — and actually call those previous clients.
Review platforms (Google, Trustpilot) give a useful indication, but beware of profiles with only recent five-star reviews: that can signal manipulation. Favour verified reviews on platforms that authenticate real clients.
A clear and detailed quote
A serious quote must include:
- A precise description of the works
- Materials to be used with brand and reference
- Unit price and total ex-/inc. VAT
- Timeframe for completion
- Payment terms
- Validity period
Any quote that is too vague ("bathroom renovation: €3,000"), with no material breakdown or revision clause, is a warning sign.
How to verify a tradesperson's qualifications
Certain trades require legal qualifications in Belgium:
| Trade | Requirement |
|---|---|
| Electrician | AREI certification mandatory |
| Heating installer | Gas competency certificate required |
| Building contractor | Trade access qualification required |
| Plumber | No mandatory licence, but liability insurance essential |
For plumbing work, construction and renovation or painting, verify that the tradesperson holds the qualifications required for the type of work planned.
The Belgian Construction Confederation and Embuild Wallonie publish lists of certified members. This is a good starting point, but federation membership does not replace your own verification.
Comparing quotes: how many should you request?
The golden rule: ask for at least three comparative quotes for any work exceeding €500. Not to be a penny-pincher — but to understand the market and spot anomalies.
A quote that is twice as cheap as average is not a bargain: it is almost always a sign of lower-quality materials, undeclared subcontracting, or a tradesperson who deliberately underquotes to win the job and then invoices "extras".
Conversely, the most expensive is not always the best. What matters is the transparency and coherence of the quote with market reality.
Red flags you must never ignore
Here are the situations that should make you say no, even if the tradesperson seems perfectly nice:
- They refuse to provide a written quote and insist on working "on trust"
- They demand more than 30% upfront before starting (except for custom material orders)
- They have no KBO/BCE number or refuse to share it
- They pressure you to decide quickly: "I have another offer tomorrow, decide now"
- They only accept cash payment with no receipt or invoice
- They cannot produce a professional liability insurance certificate
If you recognise several of these signals, walk away — regardless of the price offered.
The role of matching platforms
Platforms like Fixoo exist precisely to solve this trust problem. The principle: tradespeople are verified in advance (enterprise number, insurance, references) and client reviews are authenticated.
In practice, on Fixoo:
- Every tradesperson is verified before being listed
- Reviews are only left by clients who have actually used the service
- The from €39/year model (with no commission on your quotes) encourages professionals to offer fair prices
- In the event of a dispute, Fixoo acts as mediator
This is a fundamental difference from commission-based platforms, where the tradesperson must build 15–30% commission into their rates — which ultimately means you pay it.
Organising the job: best practices
Once you have chosen your tradesperson, a few additional precautions help avoid unpleasant surprises:
Sign a work order or contract incorporating the agreed quote, the schedule and the payment terms. A confirmation email also constitutes a commitment.
Stagger payments according to actual progress: deposit at order (max 30%), interim payments at defined milestones, balance on completion.
Draw up a handover certificate: a simple document signed by both parties confirming that the works are finished and conform to the specification. This is the starting point of the statutory ten-year decennial guarantee for structural works.
Keep all invoices, which will be useful in the event of a claim, a property sale or to benefit from the reduced VAT rate (6% for works on homes more than ten years old).
Conclusion: put transparency first
Finding a good tradesperson in Belgium is not a lottery — it is a matter of method. Check the enterprise number, insist on a liability insurance certificate, compare at least three quotes, be wary of prices that are too low and of pressure to decide quickly.
At Fixoo, we built our platform around these principles: verified tradespeople, authentic reviews and a transparent model that adds no commission to your quotes.
