In Belgium, choosing a commercial cleaning provider still comes down too often to comparing hourly rates at the bottom of a quote. Rates run between €20 and €45 per hour, excl. VAT, depending on the job (Source: Bruxelles-Nettoyage, 2025). At that level, two quotes at the same price can hide very different service. The right instinct isn't to compare prices. It's to compare guarantees. Here are 7 criteria that tell a genuine partner from a mere subcontractor. Check them before you sign, and against the contract you already have. Go through them one by one. Every box left unchecked is a blind spot to clear up before your next renewal.
A provider that cleans an open-plan office as well as a pharmaceutical cleanroom doesn't really exist. Not with the same crew, anyway. A food plant has different needs than a medical office, or a car dealership open to the public. A serious commercial cleaning provider proves it works on your type of site: offices and retail, production floors, labs, or car showrooms. Cleaning professional spaces and cleaning industrial spaces are two different trades. They call for their own methods, gear, and certs. One question settles it: how many sites in your sector do they handle today, and for how long?
A certification displayed on a website means nothing without an audit behind it. The version of the audited standard matters as much as the certificate itself. ISO 9001 covers quality. ISO 14001 covers the environment. VCA covers safety on high-risk sites. ISO 26000 covers social responsibility. The real question isn't "do you hold a certification?" but "since when?" A certificate earned six months ago is not worth the same as an audit renewed year after year. A dated, named document isn't administrative trivia. It's a signal.
The day a site flags a problem, who picks up? If the answer is "it depends," switch providers. A good cleaning contract names a single contact, with a face and a direct number, who knows your site and its history. At Clean Power, that's the Area Manager's role. We've seen it more than once. A contract renews because the same Area Manager has followed the site from day one, history in hand. Not a ticket in a software queue. A person, with a name, who answers the phone. That's what changes everything: not the promise of "availability," but the continuity of one person.
Everyone promises to be responsive. A responsiveness commitment that's worth anything is written into the contract, not slipped into a sales brochure. At Clean Power, the commitment is a reply from the Area Manager within 24 hours. On a site open to the public, or in continuous production, a two-day delay costs more than any line on a quote. What matters comes after the call: who shows up, with what gear, and how fast on site. Not just on paper. The question that reveals everything: "If I call Friday at 5 p.m. about an incident, who answers, and when?"
Say your sites are spread across Wallonia, Brussels, and Flanders. A single-branch provider forces you to juggle several contacts, several quality standards, several invoices. A network, but run in spare parts. The provider's footprint should follow your map, not the reverse. Clean Power runs 4 regional branches: Mont-Saint-Guibert, Vlaanderen, Liège, Hainaut. Together they service more than 1,700 sites a week, in French and Flemish. For an organization on a single site, this criterion matters less. The moment a second or third site opens, it becomes decisive. Changing providers each time means rebuilding the relationship from scratch. For a multi-site deal, this footprint is what makes one report and a single point of contact for your tenders possible.
A serious quote spells out the area covered, how often crews pass, the products and gear used, and the total price with VAT. Not just an hourly rate. Two quotes can only be compared on the same basis; otherwise they're two different services hiding under one price. A good provider also explains what isn't included. And at what price an extra job is added: windows, solar panels, post-build cleanup. When a provider won't itemize, the difference gets made up elsewhere: on the hours actually worked, or on the quality of the products.
A provider that's been around a long time has nothing to hide about its clients. Verifiable references in your sector are worth more than logos on a web page. Clean Power has operated for 30 years, with more than 1,300 active clients in Belgium. A written testimonial on a website doesn't replace a direct contact. You want a client in your sector you can call yourself. One call is enough. If a provider can't name a single verifiable reference in your sector, the question answers itself: why not?
Seven criteria, one outcome in mind: sleeping soundly without reopening the contract at every incident. If your current provider doesn't check these boxes, the problem isn't the price it charges. It's what it doesn't guarantee. These are the criteria our field teams check before every contract renewal. They don't guarantee a perfect provider. They guarantee that both sides know what to expect. On which point has your current provider never given you a clear answer? Ask us at cleanpower.be/contact.
