QUICK ANSWER

A specification says what is to be cleaned; an SLA describes how the service is communicated and reviewed; KPIs provide a small set of useful measures. Together, they help a multi-room or multi-site service stay clear without creating unnecessary administration.

A specification says what needs doing

A cleaning specification describes the areas, tasks, frequencies, standards, access limits and exclusions. It gives both client and contractor a shared starting point, particularly when several rooms, occupiers or locations are involved.

The most useful specifications are clear enough to guide the team without pretending that every site condition can be predicted. They should make space for a written variation when the building, condition or programme changes.

  • Areas and surfaces included.
  • Task frequency and required timing.
  • Priority standards and stated exclusions.
  • Access, security and site-contact arrangements.

An SLA explains how the service is managed

A service-level agreement sets the working relationship around the specification. It can cover reporting, site reviews, escalation, communication, agreed response expectations and how performance is discussed.

An SLA should be realistic. It is better to define a clear reporting route and review rhythm than to make blanket promises that cannot account for access restrictions, changing occupancy or a specialist requirement.

  • Named contacts and communication route.
  • How concerns and variations are logged.
  • Review meetings or checkpoints.
  • Evidence or handover expectations where agreed.

KPIs should help the site, not create noise

Key performance indicators are simple measures used to review whether the agreed service is being delivered. For a cleaning contract, they might include completed planned visits, recorded exceptions, agreed evidence and the closure of raised issues.

Use a small number of measures that match the building. A hospitality property, school holiday programme and office contract need different information. The objective is a useful conversation about service quality, not a large spreadsheet that no one uses.

  • Pick a small number of site-relevant measures.
  • Define how each measure is recorded.
  • Agree who reviews the information.
  • Use findings to improve the agreed scope.

Where to start

Start with the areas and outcomes that matter most to occupants or the client. Then add safety, access, specialist work and reporting in proportion to the scope. For larger programmes, a survey may be the best way to identify the right starting point.

CLEANWISE can work from an existing specification or help clarify the practical scope before a written estimate is confirmed.

  • List critical rooms and service priorities.
  • Separate routine from periodic or specialist work.
  • Set a realistic first review point.
  • Keep the scope easy for site users to understand.

IMPORTANT TO KNOW

Every property and site needs its own confirmed scope.

Guidance can help you prepare, but the final service depends on the condition, access, timing, safety and requirements you share. Where something needs further assessment, CLEANWISE will explain the appropriate next step.

GUIDE FAQS

Common questions about this guide.

What belongs in a cleaning specification?

Areas, task frequencies, priorities, access, operating restrictions, exclusions and the required handover information are useful starting points.

Are KPIs necessary for every site?

No. They are most useful when they help the client and contractor discuss an agreed service. A small number of relevant measures is often enough.

Can a specification include specialist work?

Yes, but specialist, exterior or project work should be clearly identified and may need separate assessment or programming.

What is the difference between an SLA and a scope?

The scope describes the cleaning work. The SLA describes the service-management arrangements around it, such as communication, reviews and issue handling.

How often should the service be reviewed?

The right rhythm depends on the building and work. It should be agreed in the scope and be frequent enough to address actual changes.
