Best office cleaning companies in Singapore (2026)

In short: Large offices or several sites suit ISS or OCS; term contracts with a mid-sized firm suit Aedge, Whissh or Avalon Services; small offices needing a few scheduled visits or a one-off deep clean suit SparkCleanz or Sureclean. Ask any firm for its NEA licence class and check it with NEA.

Which office cleaning company suits you depends on the size of your office and how much you want one provider to handle. For a large office or several sites that want cleaning run as part of facilities management, look at ISS and OCS. For a term contract with a mid-sized firm, look at Aedge, Whissh and Avalon Services. For a small office that needs a few scheduled visits a week or a one-off deep clean, look at SparkCleanz and Sureclean.

Search results for office cleaning in Singapore are padded with old forum threads and sponsored “top cleaner” articles. This guide groups seven firms by type, sets out what each one says on its own website, and explains how to choose.

How we chose

We started from firms that appear often when Singapore businesses search for office cleaning services, then kept only those whose office or commercial cleaning services we could confirm on their own websites in October 2026. We looked at:

• Type of provider. Large facilities groups, mid-sized cleaning firms, or smaller office specialists.
• NEA licence. Whether the firm states its Cleaning Business Licence and class. We could not query NEA’s public licence search when we checked, so each licence note below is what the firm says on its website. Check it with NEA before you sign.
• Service models. Daily, part-time, full-time on-site or one-off cleaning.
• Price transparency. Whether the firm publishes any pricing.

We did not rank firms by review scores or client numbers, because we could not verify them, and we left out paid directories and firms whose websites we could not load. The list is grouped by type rather than ranked.

FYAdvisers is a free matching service for Singapore businesses. Firms do not pay to appear in this list, and we describe each one only from what it says on its own website.

Quick comparison

Large facilities management groups

These groups run cleaning across many sites and usually sell it alongside other building services.

1. ISS Singapore

ISS says on its website that it has over 125 years of experience in workplace services. Its Pure Space Office programme is a standardised office cleaning service, with smart washroom sensors that direct cleaners where they are needed and an app for planned and ad hoc tasks.

Cost: Not published. The site invites you to talk to its team.

Strengths: A standardised programme and sensor-based scheduling, with other workplace services available from the same provider.

Limits: The Singapore site does not state its NEA licence class, and the programme is built for larger workplaces. A small office may get more attention from a smaller firm.

2. OCS Singapore

OCS says on its website that it offers periodical and contract cleaning for office workspaces, washroom and janitorial services, and façade, window and high-level cleaning.

These firms take term contracts for offices and commercial buildings, often with other building services alongside.

Best for: Companies that want a contractor stating the highest NEA licence class and formal safety certification.

Cost: Not published.

4. Whissh

Whissh says on its website that it is an integrated facilities management company.

Smaller office cleaning specialists

These firms suit small offices that need scheduled visits or one-off jobs rather than full-time cleaners.

6. SparkCleanz

SparkCleanz says on its website that it was founded in 2016 and is NEA licensed. Its contract office cleaning covers surfaces, toilets, rubbish, floors, interior windows and pantries, on daily, periodic or one-time plans, with off-hours scheduling and a minimum of two hours per session.

Singapore note: It lists an office at The Spire, Bukit Batok Crescent.

How to choose

Start with your office size and schedule. A small office usually needs a few visits a week from a smaller firm. A mid-sized office with busy pantries and washrooms may need part-time or full-time cleaners on a term contract. A large office or several sites suits a facilities group.

Then ask every shortlisted firm the same questions:

1. What is your NEA licence class and expiry date? Check it against NEA’s list of licensed cleaning businesses.
2. What does the quote assume? Ask for cleaners, hours and visits per week, by area.
3. How are wage increases handled? Progressive Wage Model levels rise each July, so ask how that affects a multi-year price.
4. What happens when a cleaner is absent? Get the replacement arrangement in writing.
5. Which consumables and equipment are included? Toilet rolls, soap, liners and machines are often billed separately.

Our office cleaning page covers licence classes, wage levels and red flags in more detail. If you are refitting your space first, see office renovation.
