Top 10 Office Cleaning Companies in London (2026 Guide)

Keeping your office clean is about far more than appearances. A professionally cleaned workspace supports employee wellbeing, boosts productivity, and shapes how clients perceive your business from the moment they walk through the door.

In a competitive city like London where offices range from fast-moving co-working hubs to high-security corporate buildings choosing the right office cleaning company can directly impact your reputation and daily operations.

With hundreds of providers across the capital, finding a reliable, vetted, and flexible cleaning partner can feel overwhelming. This guide simplifies the decision.

Why Is Office Cleaning So Important for London Businesses?

A clean office isn’t just visually pleasing it’s a business necessity.

Health and Hygiene

London’s dense work environments mean germs, allergens, and bacteria spread quickly. Professional office cleaners reduce illness, minimise sick days, and help maintain a healthier workforce.

Strong First Impressions

Reception areas, meeting rooms, and washrooms silently communicate your standards. A spotless office signals professionalism, attention to detail, and trustworthiness to clients and partners.

Employee Productivity and Morale

Studies consistently show that clean, organised workspaces improve focus, reduce stress, and increase overall job satisfaction.

Common Office Cleaning Services in London

Most professional office cleaning companies offer a combination of the following:

• Daily general cleaning – desks, floors, bins, communal areas
• Washroom sanitisation – toilets, sinks, high-touch surfaces
• Kitchen and breakroom cleaning – disinfecting surfaces, appliances, floors
• Glass and window cleaning – partitions, doors, internal glazing
• Carpet and upholstery cleaning – periodic deep cleans
• IT equipment sanitisation – keyboards, phones, monitors

Premium providers may also include air purification, plant care, consumables restocking, and janitorial services.

How Often Should an Office Be Professionally Cleaned?

Small Offices (1–10 staff)

• 2–3 cleans per week
• Quarterly deep cleaning recommended

Medium Offices (10–50 staff)

• Daily cleaning for shared areas
• Rotational deep cleaning weekly

Large or High-Footfall Offices

• Daily general cleaning
• Weekly deep cleans

Cleaning frequency should always reflect staff numbers, visitors, and industry requirements.

How to Choose the Right Office Cleaning Company in London?

Before signing a contract, look for these essentials:

• Insurance & certification (BICSc, SafeContractor, ISO)
• DBS-checked staff
• Clear service-level agreements (SLAs)
• Flexible contracts and scalable services

Avoid providers that cannot clearly explain what is included or who rely on vague pricing.

Working with a London-based provider offers real advantages:

• Faster response times

Local companies often outperform national chains on consistency and communication.

• Reduces chemical exposure
• Improves indoor air quality

Many London businesses now prioritise green-certified products and low-waste methods as standard.
