Office Cleaning in Oslo — fixed team, no surprises
Office cleaning is what we do, day in, day out. We take the cleaning off your plate with the same people, the same routines and written documentation on every visit. No agency fill-ins who don't know where the utility sink is. No excuses the next morning.
Most businesses switch cleaning providers for the same reason: they never know who's turning up, quality swings from week to week, and when something is missed or done wrong there is no one to talk to. We fix that simply — the same cleaners every week, names on visible HMS ID cards, and a Norwegian-speaking account manager who actually answers the phone.
Every month you receive a written report: what was done, any issues logged, and how they were resolved. You can file it against internal audits, ISO certification reviews, or simply keep it on hand as evidence for senior management. We don't need it — but it's part of running a proper operation.
The products we use are EU Ecolabel-certified. That means they're safe around colleagues with allergies and expectant mothers, and they don't leave that sharp "chemical-clean" smell that clings to clothes all day. We use microfibre cloths and refillable bottles — not aerosols and single-use plastic.
Office cleaning across Oslo's central business districts
Office cleaning in Oslo isn't one thing. An open-plan office in Bjørvika/Barcode (Oslo's waterfront business district) has very different needs from a law firm in Frogner or a tech start-up in Grünerløkka. We tailor the team and frequency to the district — and we know the local quirks that standard quotes usually miss.
In Bjørvika and Barcode we work with new-build glass offices, hot-desking and shared kitchens that need more frequent attention than a standard office. In Skøyen and Lysaker there are more tech and engineering firms with server rooms — here we use dry microfibre routines around IT kit, never aerosols. Grünerløkka and Sagene are home to smaller creative studios where low-impact products are a client requirement, not a nice-to-have. Nydalen, Helsfyr and Ensjø have mixed-use commercial buildings with reception areas and staff canteens that need coordinating.
Running into disagreements with fellow tenants about communal cleaning? We can cover your own space and the shared stairwell/lift under one contract — one invoice, one point of contact.
How often should your office be cleaned?
Frequency comes down to three things: headcount, building type and whether there is a staff canteen or meeting rooms where food is served. Here's what we recommend, based on real experience with Norwegian businesses:
| Office type | Headcount | Recommended frequency | Key focus areas |
|---|---|---|---|
| Small start-up / solicitors' practice | 5–15 | 1–2 × per week | Kitchen, toilets, bins, vacuuming |
| Mid-sized SME | 15–50 | 2–3 × per week | + meeting rooms, reception, horizontal surfaces |
| Large B2B office | 50–150 | 3–5 × per week | + daily canteen, technical rooms |
| Enterprise / 2+ floors | 150+ | Daily, 5 × per week | + shift logistics, access-card protocols |
| Co-working / hot-desk | varies | Daily | Desks wiped between each shift |
- ✓ Kitchen or canteen with hot food: always daily, regardless of size
- ✓ Open-plan offices: more frequent than cellular offices (more surface contact per m²)
- ✓ Server rooms and IT cabinets: monthly, dry-clean only
- ✓ Toilets with 30+ daily users: daily, non-negotiable
Cleaning that stands up to ISO audits and internal controls
More and more B2B businesses need documentation on everything — cleaning included. If you're ISO 9001 or ISO 14001 certified, or you work with public-sector clients who demand health-and-safety records, Rimon's monthly report drops straight into your audit file.
The report documents: which tasks were completed each week, who was on site (with HMS ID-card reference), any issues and how they were resolved, plus products used (with EU Ecolabel certification numbers). No other cleaning provider we've seen in the Oslo market delivers this in a structured format — but ISO auditors love it.
For public tenders under Norway's Public Procurement Act, we also document sector-wide wage compliance and Cleaning Services Register status automatically inside the monthly report. That's less work for you when tender paperwork is due.
GDPR and server-room cleaning
Cleaning server rooms and IT areas isn't trivial. Microfibre cloths used elsewhere can spread data fragments (shredded paper, printer toner). Dust from the wrong equipment can interfere with server ventilation.
We have dedicated protocols for IT rooms: separate dry microfibre cloths, no wet spraying, anti-static materials, and a written record confirming no documents or USB devices were touched. The HMS ID-card reference for the team that entered is recorded in the monthly report — if you face a compliance review, you have a full audit trail.
Our cleaners sign a confidentiality agreement on joining. Standard practice, rarely formalised in this industry — we put it on the table before you have to ask.

How much does office cleaning cost per square metre in Oslo?
Market rates for office cleaning in Oslo typically sit between NOK 35 and 75 per m² per month — depending on frequency, building type and any special areas (canteen, server room). A 200 m² office cleaned twice a week usually lands in the NOK 7,900–10,900/month range. We don't publish prices on the website because every contract is priced individually after a site survey — contact us for a firm written quote.
What's the difference between "office cleaning" and "kontorvask"?
In practice, the two are synonyms in Norwegian industry terminology. Some suppliers use "kontorvask" (office washing) for intensive jobs (deep floor scrubs, spring cleans) and "kontorrenhold" (office cleaning) for routine daily or weekly work. We use "office cleaning" as our default term but handle both.
How often should offices be cleaned?
It depends on headcount and building type. Rough guide: 5–15 staff = 1–2 times a week. 15–50 staff = 2–3 times. 50+ staff or open-plan = daily. Kitchens and toilets should always be cleaned daily regardless of size. See the detailed table higher up the page.
What does "allmenngjort tariff" mean in the Norwegian cleaning industry?
"Allmenngjort tariff" is a Norwegian-specific mechanism: a collective pay agreement made legally binding across the entire sector by the Tariff Board (Tariffnemnda). Minimum wages and working conditions apply to every employer, not just those who've signed up to the agreement. In cleaning, this has been in force since 2011. The minimum hourly wage is NOK 228.99 (2026). We pay it — which means your business cannot be accused of supporting social dumping by using us.
Can you clean out of hours?
Yes — and it's the norm. Most clients don't want cleaning during opening hours. We typically work 06:00–08:00 or 17:00–20:00 on weekdays, whatever fits you best. Key handling is agreed in writing.
What happens if the regular team is off sick?
An experienced cover cleaner from our in-house team steps in — never a random contractor from a pool. We message your point of contact the same day. We never leave a job unfinished without notice.
What's your notice period?
Standard is one month on either side. For larger contracts — or on request — we can agree three months. No lock-in beyond the notice period.
Are you approved by the Norwegian Labour Authority?
Yes. Rimon Renhold AS is listed in the Norwegian Labour Authority's (Arbeidstilsynet) Cleaning Services Register as "Approved with employees", company number 937 087 764. That means you can legally buy cleaning services from us — something the Norwegian Working Environment Act requires.
Can you provide documentation for ISO audits?
Yes. Our monthly report covers work completed, issues logged, HMS ID-card references and product certification numbers (EU Ecolabel). It can be filed directly into ISO 9001 / 14001 audit records and public-tender responses.
Do you take issue reports outside the billing cycle?
Yes. Your point of contact can reach us by phone or email at any time. We aim to reply within 2 hours during business hours, and always by the following morning at the latest. All issues are logged in the monthly report.
