The Challenge
Operating in Mayfair, one of London’s most prestigious business districts, our client required a reliable cleaning partner to maintain a consistently clean, hygienic and professional office environment.
The client needed a structured cleaning programme that would maintain high standards across the workplace, minimise disruption to daily operations and provide confidence that cleaning tasks were completed consistently.
Our Solution
Thornton FM delivered a tailored office cleaning programme designed around the client’s operational requirements, focusing on reliability, attention to detail and measurable service standards.
Our cleaning team covered:
- Office workspaces: Cleaning desks, surfaces and shared working areas.
- Kitchen facilities: Maintaining clean and hygienic staff kitchens and break areas.
- Washrooms: Regular cleaning and hygiene maintenance.
- Floors and communal areas: Removing dust, dirt and everyday debris.
- High-touch surfaces: Cleaning frequently used contact points.
- Waste management: Emptying bins and maintaining tidy working environments.
Our approach combined a structured cleaning schedule with clear performance expectations to support a consistently professional workplace.
Service Delivery: The Numbers
The weekday cleaning programme was structured around the following service benchmarks:
- 5 days per week of scheduled cleaning.
- 20–23 cleaning visits per month, depending on the calendar.
- Approximately 260 potential weekday visits per year, before public holidays and planned closures.
- 4 core cleaning zones covering workspaces, kitchens, washrooms and communal areas.
These figures illustrate the planned scale of a five-day-per-week service rather than verified attendance records for this specific contract.
Key Performance Indicators (KPIs)
At Thornton FM, we believe commercial cleaning should be measurable, accountable and aligned with our clients’ expectations. Our cleaning programmes can incorporate defined KPIs to monitor quality, attendance and responsiveness.

This approach provides a clear framework for monitoring service quality, identifying areas for improvement and maintaining accountability throughout the contract.
