Key Takeaways for London Office Buyers
- Janitorial services are the ongoing, scheduled maintenance cleaning layer — daily or regular visits keeping a building operational and hygienic.
- Commercial Cleaning is the umbrella term covering all professional cleaning of commercial premises — janitorial cleaning sits within it, as do deep cleaning, carpet cleaning, and specialist services.
- Most London offices need a janitorial contract as their permanent base, supplemented by specialist commercial cleaning services on a periodic schedule.
- The two terms are used interchangeably in the market, which causes buyers to underspecify their contracts. Always define scope, frequency, and exclusions in writing regardless of what the service is called.
- Sector matters: an office janitorial requirement differs structurally from a school, a hotel, or a retail environment — even when the same words describe the service.
- Citywide Cleaning Company provides both janitorial and specialist Office Cleaning London services under a single managed contract.

What Are Janitorial Services?
Janitorial services are the ongoing, regularly scheduled cleaning and maintenance tasks that keep a commercial building in a consistently clean and functional condition. They are the cleaning layer that runs continuously — daily, weekly, or on a defined schedule — rather than being called in for a specific event or periodic deep treatment.
The term comes from the role of the janitor — the building caretaker responsible for day-to-day maintenance and upkeep. In a commercial context, janitorial services cover the routine tasks that prevent a building from deteriorating between more thorough cleans: vacuuming and mopping floors, emptying bins, wiping surfaces, sanitising washrooms, restocking consumables, cleaning kitchens, and maintaining entrance areas.
For any London business operating Office Cleaning London contracts, the janitorial service is the foundation on which everything else sits. Without it, more expensive specialist commercial cleaning services are cleaning spaces that have been allowed to deteriorate — which is both inefficient and more costly than maintaining standards continuously.
What janitorial services typically include
- Vacuuming all carpeted areas and mopping all hard floor surfaces on every visit
- Dusting and wiping all desk, counter, and work surfaces
- Emptying and relining all waste bins throughout the building
- Full washroom cleaning and sanitisation — toilets, urinals, basins, mirrors, floors
- Restocking all consumables — toilet tissue, hand soap, paper towels, sanitiser, bin liners
- Kitchen and breakroom cleaning — surfaces, appliance exteriors, sink, bins, floor
- Reception and entrance maintenance — floor, desk, glass doors, bins
- Meeting room reset — surfaces, chairs, glass panels, bins
- Stairways, corridors, and lift cleaning on each visit
- Spot-cleaning of glass partitions, door handles, light switches, and high-contact surfaces
Citywide Cleaning Company's Professional Office Cleaning service is built on a fully documented janitorial specification, produced in writing before the contract starts, so every task is defined and every visit is accountable.
What Are Commercial Cleaning Services?
Commercial cleaning services is the broader category that encompasses all professional cleaning of commercial premises — any space used for business purposes, from offices and retail units to schools, hotels, warehouses, and healthcare facilities. It includes janitorial cleaning as its most common component, but extends to specialist services that address needs beyond the scope of routine maintenance.
When a London business engages a provider of Commercial Cleaning services, they may be contracting for any one or combination of the following:
Janitorial Cleaning
The ongoing, scheduled maintenance layer. Daily or regular visits covering all standard areas. The operational foundation of any commercial cleaning programme.
Professional Office Cleaning →Deep Cleaning
A thorough treatment of all areas beyond the daily cleaning scope — inside appliances, upholstery, high-level surfaces, behind furniture. Recommended twice yearly for most offices.
Deep Cleaning Services →Carpet & Floor Care
Hot water extraction, dry cleaning, or specialist floor treatments addressing embedded dirt, staining, and material degradation beyond the reach of daily vacuuming.
Carpet Cleaning for Offices →Washroom Hygiene
Specialist washroom management including periodic descaling, sanitary bin servicing, air freshener units, and quarterly deep cleaning beyond the daily janitorial scope.
Washroom Hygiene Services →School Cleaning
Specialist cleaning for educational environments — higher hygiene standards, child-safe products, term-time and holiday-period scheduling, and compliance with DfE guidance.
School Cleaning Services →Retail & Shop Cleaning
Commercial cleaning for retail environments — customer-facing presentation standards, out-of-hours access, window frontage, changing rooms, and stockroom maintenance.
Retail & Shop Cleaning →Hotel & Hospitality
Specialist cleaning for hotels, gyms, and leisure facilities — guest room turnovers, leisure suite maintenance, food preparation area compliance, and 24-hour operational flexibility.
Hotel & Hospitality Cleaning →After Builders Cleaning
Post-construction and builders cleaning for commercial spaces — removing construction dust, debris, adhesive residue, and protective coverings before a building opens for occupancy.
After Builders Cleaning →The distinction that matters for any London buyer is that commercial cleaning services describes what is being cleaned (a commercial building), while janitorial services describes how often and at what maintenance level the cleaning is delivered. One is a category; the other is an operational model within that category.
Janitorial Services vs Commercial Cleaning: Side-by-Side Comparison
This table sets out the key differences across the dimensions that matter most to London office buyers evaluating a Contract Cleaning arrangement.
| Dimension | Janitorial Services | Commercial Cleaning Services |
|---|---|---|
| Definition | Ongoing scheduled maintenance cleaning of a commercial building | All professional cleaning of commercial premises — the umbrella category |
| Frequency | Daily, three times weekly, or on a set recurring schedule | Varies by service — from daily (janitorial) to annual (specialist treatments) |
| Scope | Defined task list per visit: floors, surfaces, bins, washrooms, kitchen, consumables | Any cleaning of commercial premises — includes janitorial plus all specialist services |
| Contract type | Ongoing scheduled contract — weekly, monthly, annual | Can be ongoing contract or one-off engagement depending on service type |
| Who delivers it | Dedicated cleaning operative(s) assigned to your building on a regular schedule | Specialist teams for deep cleaning, carpet care, washroom services; general operatives for daily work |
| Typical cost model | Weekly or monthly contract rate based on scope and visit frequency | Contract rate for ongoing services; one-off pricing for specialist treatments |
| What it does NOT cover | Deep cleans, carpet cleaning, external windows, specialist treatments, consumables supply (unless specified) | Domestic (residential) cleaning — commercial cleaning applies specifically to business premises |
| Relationship | A subset of commercial cleaning services | The parent category — includes janitorial cleaning as its most common component |
Why the Confusion Exists — and Why It Matters
The terms janitorial services and commercial cleaning services are used interchangeably throughout the London cleaning market — by providers, by buyers, and even by facilities management professionals who work with both every day. There are two reasons for this confusion, and understanding them helps any buyer avoid the contractual gap that the confusion creates.
Reason 1: Most providers offer both under the same label
When a London provider of Office Cleaning London services quotes for your building, they typically price a package that combines a janitorial maintenance schedule with some level of periodic deep cleaning, consumables supply, and perhaps washroom hygiene management. The whole thing gets labelled "commercial cleaning" or "office cleaning" on the contract, with no clear boundary drawn between the ongoing janitorial scope and the specialist services layered on top of it.
This creates the problem: when something goes wrong — the carpet is never deep cleaned, the consumables run out and nobody restocks them, the washroom descaling never happens — there is no written reference point to resolve the dispute. Was it included or excluded? The contract says "commercial cleaning." That tells you nothing about which specific tasks were agreed.
Reason 2: Buyers do not ask for specifics upfront
Most London offices sign a cleaning contract based on a price per visit and a verbal description of what is included. The written contract follows later, usually as a standard template with minimal customisation. The janitorial tasks are assumed. The specialist services are not mentioned. The exclusions are not listed.
A well-managed Managed Workspace Cleaning contract addresses this by producing a written cleaning specification before the contract starts — naming every area, every task, every frequency, and every exclusion. That document is what makes a cleaning contract enforceable and what makes the janitorial versus commercial cleaning distinction practically irrelevant, because every element of both is defined in writing.
Which Does Your London Office Need?
The honest answer for most London offices is: both, structured correctly. A janitorial contract as the permanent ongoing foundation, with specialist commercial cleaning services scheduled periodically on top of it. The question is not which one you choose — it is how you specify each one and how clearly the boundary between them is drawn in your contract.
You need a janitorial service if:
- Your office has more than five regularly occupied desks and is used three or more days per week
- You have washrooms and a kitchen used by multiple staff daily
- You have a client-facing reception or meeting rooms that need to maintain a consistent presentation standard
- You are currently relying on staff to manage cleaning duties — a structural arrangement that costs more than it saves once staff time is properly costed
- You have had inconsistent cleaning from an ad-hoc arrangement and need a structured, supervised alternative
You need specialist commercial cleaning services if:
- Your office has carpeted areas that have not been professionally cleaned in the past six to twelve months
- Your washrooms require descaling, sanitary bin replacement, or air freshener unit servicing beyond the daily clean
- You are moving into a new space and need a thorough one-off Deep Cleaning Services treatment before occupancy
- You are vacating a commercial premises and need an End of Tenancy Commercial Cleaning to meet lease obligations
- You have had construction, renovation, or fit-out work completed and need an After Builders Clean before staff return
- You run a school, hotel, retail space, or hospitality venue with sector-specific hygiene and compliance requirements

Frequently Asked Questions
Are janitorial services the same as commercial cleaning?
Not exactly. Janitorial services are a type of commercial cleaning — the ongoing, scheduled maintenance layer. Commercial cleaning is the broader category that includes janitorial cleaning alongside specialist services such as deep cleaning, carpet cleaning, and washroom hygiene management. Every janitorial service is a commercial cleaning service, but not every commercial cleaning service is janitorial in nature.
What does a janitorial cleaning contract include for a London office?
A standard janitorial contract covers all routine maintenance tasks on every visit: vacuuming and mopping all floors, wiping and dusting all surfaces, emptying and relining bins, full washroom cleaning and sanitisation, kitchen and breakroom cleaning, restocking consumables, and maintaining reception and entrance areas. Any tasks beyond this — interior appliance cleaning, deep carpet treatment, external windows, specialist sanitisation — are typically excluded from the janitorial scope and should be priced separately as part of a broader commercial cleaning programme.
How often should janitorial services visit a London office?
For a fully occupied five-day office, daily janitorial cleaning is the professional standard. For hybrid offices operating at 50 to 70 percent capacity across three or four days, three cleaning visits per week with daily or near-daily attention to washrooms and kitchens typically meets the requirement. Any frequency should be calibrated to your actual current occupancy, not a pre-pandemic baseline. Citywide reviews cleaning frequency at every contract renewal to ensure the schedule reflects how your office is actually being used. See our Office Cleaning London page for frequency guidance by office type.
What specialist commercial cleaning services does a London office typically need beyond janitorial?
Most London offices require professional carpet cleaning one to twice yearly, a full deep cleaning at least twice a year, periodic washroom hygiene servicing beyond the daily janitorial scope, and specialist treatments at lease events — end of tenancy, post-construction, or pre-occupancy. The exact schedule depends on office size, occupancy level, and the nature of the business using the space.
Do I need a different provider for janitorial cleaning and specialist commercial cleaning?
No. Citywide Cleaning Company provides both under a single Contract Cleaning arrangement, with each service documented separately so scope, frequency, and cost are clear for every element. Having a single provider for both the janitorial and specialist commercial cleaning layers simplifies your vendor management, improves coordination between service types, and ensures that the team managing your daily clean also understands the periodic service schedule.
How does Citywide Cleaning Company structure its contracts?
Every Citywide contract begins with a written cleaning specification covering the full janitorial scope — every area, every task, every frequency. Specialist Commercial Cleaning services are documented separately with their own schedule and pricing. All exclusions are stated explicitly. DBS-checked, COSHH-trained operatives deliver the janitorial work on a fixed schedule, with same-day absence cover as a contractual obligation and a named account manager conducting scheduled on-site quality inspections and producing written QA reports after every visit.
Are cleaning services for schools and retail the same as office janitorial services?
No. While the underlying principles are similar, sector-specific environments have their own requirements. School cleaning services must meet DfE hygiene guidance, use child-safe products, and accommodate term-time and holiday scheduling. Retail and shop cleaning prioritises customer-facing presentation, out-of-hours access, and shopfloor turnover speed. Hotel and hospitality cleaning requires 24-hour flexibility, guest room turnovers, and food hygiene compliance. Citywide Cleaning Company provides specialist cleaning services across all of these sectors with operatives and specifications tailored to each environment's specific requirements.
