Most disappointing cleaning contracts don’t fail because the provider was bad — they fail because the specification was vague. If your tender document only says “clean the office to a high standard,” you’ve left every important detail to interpretation, and that gap is where missed cleans, disputes and creeping costs live. This guide walks through how to write an office cleaning specification that gets you comparable quotes and a contract you can actually hold a provider to.
Quick answer: A good office cleaning specification defines what is cleaned, how often, to what standard, and how it’s checked. At minimum it should include an area-by-area scope, a frequency table (daily / weekly / periodic), the required standards and any compliance needs, who supplies consumables and equipment, access hours, and the KPIs used to measure performance. A clear spec lets providers quote like-for-like — so you’re comparing service, not guessing.
Why the specification matters more than the price
When you send a loose brief to three cleaning companies, you get three quotes that look comparable but describe completely different levels of service. One prices a light daily tidy; another prices full washroom servicing, periodic floor care and supervision. The cheapest number wins the tender, and six weeks later you’re wondering why the kitchens are never properly done. A detailed specification removes that ambiguity. It forces every bidder to price the same scope, which is the only way to compare them fairly — and it becomes the reference document you point to when standards slip.
1. Scope: define the areas, room by room
Start by listing every area to be cleaned and grouping it by type, because different spaces need different treatment. Reception and client-facing areas carry your first impression; washrooms and kitchens are hygiene-critical; open-plan floors, meeting rooms, stairwells, lifts and breakout spaces each have their own needs. Note anything unusual — a server room that must not be touched, a gym, showers, a canteen, external glass, or a loading bay. The more precisely you describe the estate, the fewer “that wasn’t in our quote” conversations you’ll have later.
2. Frequency: the heart of the spec
This is the section that actually defines your service. Set out, task by task, how often each thing happens. The clearest way is a simple table.
| Task | Frequency |
|---|---|
| Washrooms — clean, sanitise, restock | Daily (or multiple times daily in busy sites) |
| Kitchens / breakout — surfaces, sinks, bins | Daily |
| Desks / hot desks — wipe on clear-desk basis | Daily |
| Vacuuming — walkways & open plan | Daily to 3× weekly |
| Meeting rooms — reset & clean | Daily / after use |
| Full dusting, skirtings, internal glass | Weekly |
| Carpet extraction, hard-floor treatment | Periodic (monthly–quarterly) |
| High-level dusting, vents, washroom descale | Periodic (quarterly) |
Match frequency to footfall, not habit. A busy 200-desk floor and a quiet 20-desk suite should not have identical schedules.
3. Standards, compliance and consumables
State the standard you expect and any framework it should meet — for many offices that’s simply a consistent, auditable clean, but regulated or healthcare-adjacent spaces may reference BICSc methods or colour-coded systems to prevent cross-contamination. Be explicit about who supplies what: cleaning materials and machinery are almost always the provider’s, but washroom consumables (soap, paper, sanitary units) are sometimes yours and sometimes theirs — decide, and write it down. Cover access and security too: what hours the team works, key-holding or fob arrangements, and any DBS or vetting requirements.
4. Performance: how you’ll measure it
A specification without measurement is a wish list. Define how performance is checked — periodic supervisor audits scored against the frequency table, a response time for issues, and a small set of KPIs you’ll actually review. You don’t need dozens; audit score, complaint resolution time and consumable availability cover most of what matters. Setting these out in the tender tells serious providers you’ll be paying attention, which tends to attract the ones who run managed, supervised contracts rather than send one unmanaged cleaner and hope.
Putting it out to tender
With scope, frequency, standards and KPIs written down, you can issue the same document to every bidder and get genuinely comparable quotes. Ask each to price against your spec, describe how they’ll resource and supervise it, confirm insurance and how they handle TUPE if you’re switching provider, and provide a couple of reference sites in your sector. The quote that reflects your spec — not the lowest headline rate — is usually the one that survives contact with reality. If you’d rather not build the document from scratch, a provider can walk the site and draft the specification with you as part of a office cleaning proposal.

Frequently asked questions
What should an office cleaning specification include?
At minimum: an area-by-area scope of everywhere to be cleaned, a frequency table showing how often each task is done (daily, weekly, periodic), the required standards and any compliance needs, who supplies consumables and equipment, access hours and security arrangements, and the KPIs used to measure performance. Together these let every provider quote the same scope, so you compare service rather than guessing what each price actually covers.
Why do I need a written spec instead of just asking for a quote?
Because a loose brief produces quotes that look comparable but describe different services — one prices a light tidy, another prices full washroom servicing and periodic floor care. The cheapest number wins, then standards disappoint. A written specification forces every bidder to price identical scope, which is the only fair way to compare them, and it becomes the reference document you hold the provider to when performance slips.
How do I decide cleaning frequencies?
Match frequency to footfall and hygiene risk, not habit. Hygiene-critical areas — washrooms, kitchens, entrances — are cleaned daily and never stretched. Vacuuming and meeting-room resets run daily to a few times weekly depending on use. Full dusting is typically weekly, and heavier tasks like carpet extraction and hard-floor treatment are periodic (monthly to quarterly). A busy floor needs a tighter cycle than a quiet one, so tune the table to how each area is actually used.
Who supplies cleaning materials and consumables?
Cleaning materials and machinery are almost always provided by the cleaning company as part of the contract. Washroom consumables — soap, hand towels, toilet paper, sanitary units — vary: some contracts include them, others leave them with the client. This is exactly the kind of detail a specification should state explicitly, because an unspoken assumption here is a common source of disputes and unexpected costs later.
What is TUPE and does it affect my cleaning tender?
TUPE (Transfer of Undertakings) can mean that when you switch cleaning providers, the existing cleaning staff transfer to the new provider on their existing terms. It often applies to cleaning contracts, so your tender should ask bidders how they handle it. A provider experienced with TUPE will manage the consultation and transfer properly, which protects continuity of service and keeps you clear of employment-law problems during mobilisation.
