A practical guide for Facilities Managers and Procurement Directors managing multi-tenanted and portfolio assets across London.

In London’s office market, the competition for quality tenants has never been more intense. As hybrid working reshapes how organisations think about space, tenants are no longer simply comparing lease terms and location. They are evaluating the daily experience of being in a building and few factors shape that experience more profoundly, or more quietly, than cleanliness.

For Facilities Managers and Procurement Directors tasked with managing multi-tenanted or portfolio assets across the capital, cleaning is too often treated as a commodity. A line item to be compressed at contract renewal. The evidence suggests this is a costly mistake. In 2026, cleaning standards sit at the intersection of health, reputation, compliance, and employee experience. Get it right, and you create environments where tenants stay, grow, and advocate for your building. Get it wrong, and you accelerate the decision to leave, quietly, long before any formal notice is served.

The New Expectations of the Post-Pandemic Tenant

COVID-19 permanently recalibrated how occupants relate to their built environment. Hygiene moved from background assumption to front-of-mind priority. In research conducted across UK office users since 2021, cleanliness consistently ranks among the top three factors influencing satisfaction with a workspace, sitting alongside connectivity and air quality, and above amenities once considered premium.

London tenants, particularly those in the professional services, financial, and life sciences sectors, now expect visible cleaning as a baseline standard, not a differentiator. Touchpoint cleaning regimes, hygiene station maintenance, and proactive floor-level presentation are expected during occupied hours, not just during the overnight clean. In premium buildings from Canary Wharf, the City to White City and Kings Cross, operators who have invested in visible, daytime cleaning have measurably stronger tenant renewal rates.

This is precisely the model JPC by Samsic was built to deliver. As London’s only cleaning provider operating a full Concierge Cleaning model, JPC places trained, visible staff at the heart of the building experience, not tucked away in back-of-house operations. Our Customer Experience Cleaning service aligns cleaning operatives with front-of-house standards, ensuring occupiers and their visitors encounter a building that is actively maintained throughout the working day, not just prepared the night before.

Tenants do not separate “the building” from the experience of using it. Dirty common areas are a direct reflection on management and a reason to look elsewhere at lease break.

First Impressions Set Retention Trajectories

A tenant’s decision to renew is rarely made at contract break. It is made in dozens of micro-moments over the course of the tenancy and the reception area, lift lobbies, washrooms, and breakout spaces are where those micro-moments accumulate into a verdict.

Consider the journey of a prospective client visiting a tenant’s office. They form an impression of the building before they form an impression of the business. A gleaming reception with fresh fragrance, spotless lift interiors, and immaculate washrooms elevates the tenant’s standing. Conversely, a smeared glass panel, a persistent odour in the stairwell, or a lift with marks on the walls creates a subtle but real association, one that reflects not only on building management, but on the tenant operating within it.

JPC by Samsic’s Concierge Solutions service is specifically designed to address this dynamic. Deployed across landmark assets including The Leadenhall Building, Regent’s Place, and Broadgate, our concierge-aligned teams are trained in an industry-leading customer experience programme developed in partnership with Investor in Customers (IIC), the only accredited CX training of its kind in the London cleaning sector. The result is not just a clean building, but a building that feels cared for: a distinction that tenants and their clients notice immediately, and that property managers can observe directly in occupier satisfaction scores.

CBRE’s 2024 London Occupier Survey found that 68% of office occupiers cite the quality of building maintenance and cleanliness as a key factor when deciding whether to renew or relocate, ranking it above café provision, gym access, and on-site parking.

Washrooms: The Most Important Space in Your Building

If there is a single space that most reliably determines a tenant’s assessment of a building, it is the washroom. No other area is so consistently cited in occupier satisfaction surveys and no other area degrades so rapidly when cleaning frequency is reduced.

In multi-tenanted London buildings, particularly those with shared facilities across floors, washroom maintenance is a perennial source of friction. When Facilities Managers receive complaints, washrooms feature disproportionately. When tenants raise concerns to their brokers at lease break, washrooms and common-area hygiene are routinely cited as evidence of a building operating below standard.

JPC by Samsic’s dedicated Washroom & Hygiene service goes beyond routine attendance. Our washroom management programmes combine scheduled daytime attendant visits with digital audit logging, giving Facilities Managers a transparent compliance record at all times. Our Low-Carbon Consumables range and Menstruation Solutions provision also allow buildings to meet the growing expectation for sustainable, inclusive hygiene standards; details that increasingly matter to occupiers with strong EDI and ESG commitments. A JPC-managed washroom is not simply clean. It is compliant, auditable, and aligned to the values of the organisations occupying the floors above it.

The ESG Dimension: Sustainability as a Retention Driver

London’s corporate occupier base has shifted materially in the last three years. ESG reporting obligations, net-zero commitments, and increasingly sophisticated procurement teams mean that tenants now scrutinise the sustainability credentials of their service providers including, explicitly, their facilities management supply chain.

For Procurement Managers under pressure to demonstrate Scope 3 emissions reductions, the cleaning contract is no longer invisible. The products used, the delivery vehicles run, the waste generated, the chemical discharge profile, all of which sit within a tenant’s sustainability lens.

Our frontline ESG Officers, embedded at client sites, ensure that sustainability is not a policy document but an operational reality: non-toxic product chemistry, electric cleaning equipment, waste and water reduction programmes, and social mobility initiatives that contribute directly to a building’s social value metrics.

JPC by Samsic holds 14 national and European awards for sustainability and customer experience, including the IWFM Impact Award for Excellence in Customer Experience. For landlords and managing agents constructing a compelling ESG narrative for current and prospective occupiers, our credentials are a tangible differentiator, not a marketing footnote.

Wellbeing, Air Quality, and the Invisible Cost of Poor Practice

The relationship between cleaning, indoor air quality, and occupant wellbeing is supported by a growing body of evidence. Buildings where dust, allergens, and microbial load are effectively managed through systematic cleaning see measurably lower absenteeism, higher productivity self-reporting, and better WELL or BREEAM performance scores.

JPC by Samsic’s data-led cleaning model directly addresses this. Our footfall-responsive cleaning approach informed by real-time building occupancy data, ensures that cleaning resource is deployed where and when it is most needed, rather than on a fixed schedule that takes no account of how the building is actually being used on any given day. In buildings where hybrid working creates highly variable occupancy patterns across the week, this intelligence-driven model is both more effective and more sustainable than conventional scheduled cleaning.

Our co-botics programme which deploys collaborative robotic cleaning equipment alongside trained operatives further enhances the quality and consistency of deep-clean provision, particularly in high-footfall areas such as entrance lobbies, lift banks, and food and beverage zones. The result is a cleaning operation that protects indoor environment quality continuously, not just in the intervals between human visits.

What Best Practice Looks Like in 2026

The most effective cleaning operations in London’s premium workspace sector share a number of characteristics. These are the benchmarks Facilities Managers and Procurement teams should be measuring their current provision against and the standards that JPC by Samsic delivers as standard:

  • Visible daytime cleaning across all common areas via a Concierge Cleaning model, not just overnight cycles.
  • Auditable washroom inspection regimes with digital logging, transparent management reporting, and low-carbon consumables.
  • Dedicated account management with direct escalation access, not a call centre backed by AI-powered CX mapping to identify and resolve issues proactively.
  • Trained operatives with IIC-accredited customer experience standards, who represent the building as well as clean it.
  • A certified sustainability framework: real-time carbon reporting via the JPC Materiality Tracker, non-toxic product chemistry, electric equipment, and embedded ESG Officers on site.
  • Living Wage employer status and demonstrable social value programmes, including local recruitment and social mobility initiatives.
  • Technology-enhanced quality assurance: co-botics for consistent deep-clean performance, footfall-responsive scheduling, and real-time operational dashboards.
  • Proactive, not reactive, service delivery issues identified and resolved before tenants raise them.

The Procurement Conversation Worth Having

For Procurement professionals, cleaning contracts are often renewed on the basis of historical price benchmarking and incumbent inertia. The result is a gradual erosion of service quality and, with it, tenant confidence.

A more sophisticated procurement approach looks beyond headline cost to assess total value: the quality and consistency of service delivery, the calibre and retention of frontline staff, the provider’s technology capability, and the depth of their sustainability credentials. JPC by Samsic’s track record includes partnerships maintained continuously for over 20 years, a reflection of the account management depth, operational consistency, and genuine investment in client outcomes that define our model.

When evaluating your current cleaning provision, the questions worth asking are: Does our provider offer a Concierge Cleaning model, or an overnight-only service? Can they produce auditable sustainability data that feeds into our reporting obligations? Are their operatives trained to a customer experience standard? Do they understand our tenants’ needs or just their square footage? If the answers are unsatisfying, it may be time for a building walkthrough with a partner who operates to a different standard.

The Bottom Line

In a London workspace market where tenants have options, where hybrid working has made every occupied day a test of the building’s value proposition, and where ESG accountability runs through the supply chain, cleaning is no longer a background function. It is a front-line retention tool.

Facilities and Procurement Managers who recognise this and who procure accordingly are protecting their buildings’ occupancy rates, their reputation in the broker community, and the long-term capital value of the asset. Those who treat cleaning as a cost to be minimised are, often without realising it, making a retention problem inevitable.

The question is not whether your tenants notice the cleaning. They do. The question is whether what they notice makes them want to stay.
