Office Cleaning Services in London: The Complete 2026 Guide for UK Businesses

Walk into a well-maintained office and you feel it immediately - fresh air, clear surfaces, floors that don’t catch the light with grime. Walk into a poorly cleaned one and you feel that too, whether you notice it consciously or not.

For businesses operating in London, office cleanliness is never just a housekeeping matter. It shapes how clients perceive you, how employees feel about coming to work, and whether your space meets the health and safety standards expected of any UK employer. And yet, choosing the right professional office cleaning service - and managing that relationship effectively - is something many businesses get wrong.

This guide covers everything you need to make a confident, informed decision in 2026: what office cleaning services include, how to spec your cleaning schedule, what a good contract looks like, and why the greener choice is increasingly also the smarter one.

What Do Office Cleaning Services Actually Include?

The term “office cleaning” covers a wide range of tasks, and what’s included varies significantly between providers. Before signing any contract, it’s worth being clear on the difference between routine cleaning, periodic cleaning, and deep cleaning - because conflating them is one of the most common sources of dissatisfaction.

Routine (daily or weekly) office cleaning

This is the core of most commercial office cleaning contracts in London. Typically carried out before staff arrive in the morning or after they leave in the evening, routine cleaning covers:

• Emptying bins and replacing bin liners
• Vacuuming carpets and mopping hard floors
• Wiping down desks, workstations, and shared surfaces
• Sanitising kitchen areas, including countertops, sinks, and appliance exteriors
• Cleaning and restocking washrooms - soap dispensers, paper towels, toilet rolls
• Spot-cleaning glass partitions and internal windows
• Reception and entrance areas - often the first point of contact for visitors

In a hybrid office where attendance fluctuates day by day, a good provider should be able to flex the frequency and scope of cleaning around actual usage - not just show up on a fixed schedule regardless of whether the space was used.

Periodic cleaning tasks

Beyond the daily routine, certain tasks need less frequent but equally professional attention:

• Full carpet and upholstery cleaning (typically quarterly)
• External and high-level window cleaning
• Hard floor stripping, polishing, and sealing
• Deep cleaning of kitchen equipment - ovens, fridges, dishwashers
• Air vent and duct cleaning
• Sanitisation of high-touch points such as lift buttons, door handles, and light switches
  
  

One-off deep cleaning

Distinct from routine maintenance, a professional office deep clean tackles the build-up that day-to-day cleaning doesn’t reach - behind furniture, beneath carpets, inside kitchen equipment, and along skirting boards and coving. Most London businesses schedule these annually, on a change of tenancy, or following a high-traffic event.

How Often Should You Have Your Office Professionally Cleaned?

There’s no single right answer - frequency depends on the size of your team, the nature of your work, and how much foot traffic your space sees. Here’s a practical starting framework for London businesses:

It’s also worth reviewing frequency whenever your occupancy pattern changes significantly. The rise of flexible working means many London businesses are over-cleaning empty floors on low-attendance days while under-cleaning on peak days. A reputable office cleaning company in London should help you calibrate this - and IoT-based occupancy monitoring is increasingly being used to drive smarter, demand-led scheduling.

The Case for Eco-Friendly Office Cleaning in London

The move toward green office cleaning has shifted from a nice-to-have to an increasingly mainstream expectation - particularly for businesses with ESG reporting obligations or sustainability commitments.

Traditional cleaning products can contain volatile organic compounds (VOCs), harsh disinfectants, and synthetic fragrances that affect indoor air quality and contribute to chemical runoff. In a modern workplace with good ventilation but sealed windows, these chemicals can linger at concentrations that affect how people feel and think during the working day.

Eco-friendly alternatives - plant-based detergents, biodegradable disinfectants, microfibre-based cleaning methods that reduce water and chemical usage - achieve the same or better hygiene outcomes while removing this concern. At Green Facilities, we have used environmentally responsible products since our founding, and our EcoVadis Bronze accreditation and B Corp certification reflect this long-standing commitment.

What to look for in a green office cleaning provider

• Independent environmental certification - ISO 14001, EcoVadis, or equivalent
• Transparency about which products are used and their environmental credentials
• Microfibre cleaning systems that reduce single-use consumables
• A policy on chemical storage, COSHH compliance, and staff training
• Waste segregation practices - do they support your recycling compliance?

In 2026, with UK Simpler Recycling regulations requiring workplaces to sort waste streams consistently, your cleaning provider’s waste-handling approach directly affects whether your business stays compliant.

What Should a Professional Office Cleaning Contract Include?

One of the most common mistakes London businesses make when procuring office cleaning services is not specifying enough detail upfront - and then being disappointed when the service doesn’t match expectations. A well-structured contract protects both sides and leaves nothing to interpretation.

Here are the key elements every office cleaning contract should address:

Scope of works

A detailed, room-by-room breakdown of what will be cleaned, how often, and to what standard. Vague terms like “general cleaning” are not enough. Each area - desks, kitchen, washrooms, reception, meeting rooms - should have its own listed tasks and frequency.

Cleaning schedule and access arrangements

When will cleaning take place? Out of hours? During the working day? Who holds keys or access codes? What happens to scheduling when the office is closed for a bank holiday? These logistics matter more than people realise until something goes wrong.

Products and equipment

Will the cleaning company supply their own products and equipment, or use yours? If theirs, you should have the right to know what’s being used - particularly if you have green procurement policies or staff with chemical sensitivities.

Staffing and vetting

Who will be cleaning your office? Are they directly employed or subcontracted? What background checks are conducted? For London offices handling sensitive data or operating in regulated sectors, DBS checks and confidentiality procedures are non-negotiable.

Quality control and reporting

How does the provider measure and report on quality? Is there a dedicated point of contact? What’s the process for raising a complaint or requesting a re-clean? Regular audits and a named account manager are signs of a professional operation.

Insurance and liability

Public liability insurance (minimum £5 million for UK commercial cleaning) and employers’ liability cover should be in place and verified, not just asserted.

Contract length and exit terms

Be cautious of very long initial contract periods (more than 12 months) without a performance review clause. A reputable cleaning company should be confident enough in its service that a fair exit clause isn’t a concern.

Office Cleaning and Infection Control: What London Businesses Need to Know

Workplace infection control has received more scrutiny in recent years, and for good reason. An average office desk carries significantly more bacteria than a toilet seat - and high-touch surfaces such as keyboards, door handles, lift buttons, and shared kitchen equipment are transmission hotspots that standard daily cleaning alone won’t fully address.

A professional office cleaning service should incorporate infection control thinking into its standard protocols, not just as a reactive measure. This means:

• Using hospital-grade disinfectants on high-touch surfaces as a routine, not an add-on
• Following the correct six-step cleaning and disinfection sequence - clean first, then disinfect, in the right order with appropriate dwell times
• Using colour-coded cloths and mops to prevent cross-contamination between washrooms, kitchens, and desk areas
• Staff trained in COSHH regulations and the correct handling and dilution of cleaning chemicals

If your office has experienced a norovirus outbreak, a respiratory illness cluster, or any incident requiring enhanced hygiene, a targeted infection prevention clean goes beyond the routine to provide documented assurance that the environment is safe to return to.

COSHH Compliance and Your Office Cleaning Provider

Under the Control of Substances Hazardous to Health (COSHH) Regulations, any business using or overseeing the use of cleaning chemicals has legal duties. In practice, this means your office cleaning company should:

• Hold current COSHH assessments for every product used on your premises
• Ensure cleaning staff are trained in safe chemical handling and aware of emergency procedures
• Store chemicals correctly - properly labelled, in appropriate containers, away from food preparation areas
• Have up-to-date Safety Data Sheets (SDS) available and accessible

When you outsource cleaning, the legal responsibility doesn’t disappear entirely from your side - you retain a duty to ensure the contractors working on your premises are compliant. Asking to see a provider’s COSHH documentation before signing a contract is entirely reasonable, and any reputable company will provide it without hesitation.

What to Look for When Choosing an Office Cleaning Company in London

London has hundreds of commercial cleaning companies - the challenge isn’t finding one, it’s finding the right one for your specific workplace. Here’s a practical checklist:

1. Accreditations and certifications

Look for ISO 9001 (quality management), ISO 14001 (environmental management), and Safe Contractor or Alcumus SafePay accreditation. B Corp certification and EcoVadis ratings signal a broader commitment to responsible practice. These aren’t just badges - they require ongoing independent audits.

2. Experience in your sector

Cleaning a law firm’s open-plan office is different from cleaning a digital agency’s creative studio or a financial services firm’s trading floor. Ask for references from similar environments - not just testimonials, but client contacts you can actually speak to.

3. London-based operation

A locally based team means faster response times for reactive cleans and easier communication. Check whether the company has its own London-based management and whether the cleaning staff assigned to your office are genuinely local.

4. Transparent pricing

Be wary of very low quotes that don’t reflect the true scope of work - they usually mean shortcuts somewhere: underpaid staff, reduced chemical quality, or fewer hours than specified. A fair quote breaks down costs clearly and invites scrutiny.

5. Communication and account management

You should have a named account manager, not just a call centre number. Test responsiveness during the sales process - if they’re slow to communicate before they have your business, that pattern rarely improves once the contract is signed.

6. Alignment with your values

For businesses with ESG commitments or sustainability targets, your cleaning company is a supply chain partner. Check their environmental policies, ask about their Living Wage accreditation, and find out how they treat their staff. In 2026, your stakeholders - and increasingly your auditors - may ask.

Frequently Asked Questions About Office Cleaning Services in London 

How much do office cleaning services cost in London?

Costs vary depending on office size, frequency, and scope. As a rough guide, a small London office (up to 1,000 sq ft) cleaned three times per week typically starts from around £300–£500 per month. Larger open-plan offices cleaned daily with additional specialist tasks will be priced individually. Always ask for a detailed, itemised quote rather than a single headline figure.

Can we have our office cleaned during working hours?

Yes - many cleaning companies offer daytime cleaning teams, which is increasingly common in hybrid workplaces with flexible attendance. Daytime cleaning also allows quality issues to be flagged and addressed immediately rather than discovered the next morning. It can also reduce the security burden of out-of-hours access.

What’s the difference between contract cleaning and ad-hoc cleaning?

Contract cleaning is a scheduled, regular service under a formal agreement - typically providing the best value and consistency. Ad-hoc or one-off cleaning is booked as needed, often at a higher per-visit rate, and is suited to occasional deep cleans, post-event clean-ups, or end-of-tenancy cleaning.

Do office cleaning companies provide their own supplies and equipment?

Most professional commercial cleaning companies supply everything themselves - cleaning products, microfibre cloths, mops, vacuum cleaners, and any specialist equipment. This is usually the preferred arrangement, as it ensures products are COSHH-compliant and staff are trained in their use. Confirm this upfront when requesting a quote.

How do I know if my current office cleaning is good enough?

Ask your staff - they’ll tell you quickly. Beyond that, look for visible dust on horizontal surfaces above eye level, grubby light switches and door plates, odours in the kitchen or washrooms, and carpet pile that looks matted rather than brushed. A professional cleaning audit or consultancy assessment can give you an objective benchmark.

Is it worth paying more for an eco-certified cleaning company?

 For most London businesses, yes - particularly those with sustainability commitments, ESG reporting requirements, or staff who care about their working environment. Eco-certified providers use products that are safer for occupants, better for the environment, and - because they often use more efficient methods like microfibre - can actually reduce total chemical and water usage compared to conventional cleaning.
