Office cleaning checklist & specification guide

Why most office cleaning contracts slide

Almost every office cleaning relationship that goes wrong goes wrong the same way. The contract was agreed on price and a one-line description ("general office cleaning, three times weekly") and nobody wrote down what that meant. Six months later the washrooms are not what they were, and there is no document to point at.

The fix is boring and effective: a written specification listing every task and its frequency. It protects you, because standards become measurable , not a matter of opinion. It also protects a good contractor, because it stops the scope quietly expanding until the price no longer covers the work.

The checklist below is the one we build office specifications from. Not every item belongs in every contract, a six-person office with no visitors does not need the same specification as a thirty-person office with client meetings, but everything in it should be a deliberate decision , not an omission.

Daily

• Waste and recycling emptied, liners replaced
• Washrooms cleaned, sanitised and descaled
• Washroom consumables restocked: soap, paper, hand towels
• Kitchen and breakout surfaces, sink and taps
• Fridge, microwave and dishwasher exteriors
• Desks wiped in clear-desk areas
• High-touch points sanitised: door handles, handrails, light switches
• Reception and client-facing areas prioritised
• Meeting rooms reset and surfaces wiped
• Entrance glass and door glass
• Hard floors vacuumed and mopped
• Carpets vacuumed in traffic areas
• Spot-clean spills and marks

Washrooms and kitchens belong on the daily list in any office where people are present daily, regardless of headcount. They deteriorate on a daily cycle and they are where staff judge cleaning standards.

Weekly

• All desks wiped, including under monitors where accessible
• Telephones and shared keyboards sanitised
• All carpeted areas fully vacuumed, including under desks
• Internal glass and partitions
• Skirting boards and door frames
• Kitchen cupboard fronts and appliance handles
• Fridge interior checked, out-of-date items flagged
• Dishwasher filter cleaned
• Washroom tiling and grout
• Mirrors and chrome polished
• Stair treads, risers and handrails
• Lift interior, doors and tracks
• Bins cleaned inside as well as emptied

Monthly

• High-level dusting: tops of cupboards, shelves, frames
• Light fittings and diffusers dusted
• Air vents and grilles
• Radiators, front, back and between fins
• Window sills, frames and internal glass throughout
• Upholstered chairs vacuumed
• Under and behind moveable furniture
• Kitchen cupboard interiors
• Appliance descaling: kettle, coffee machine, dishwasher
• Washroom deep clean including behind pans and sealant
• Fire door checks for cleaning obstructions

Quarterly and annual

• Carpet cleaning of entrance areas and traffic lanes (quarterly)
• Full carpet clean throughout (annual)
• Hard floor strip and reseal where applicable (annual)
• Fabric office chairs cleaned (annual)
• Kitchen deep clean including inside all appliances (quarterly)
• Staff kitchen oven and microwave deep clean (quarterly)
• External window cleaning (quarterly, specialist)
• High-level cleaning above two metres (annual, with access equipment)
• Full washroom descale and sealant renewal review (annual)

Traffic-lane carpet cleaning quarterly with a full clean annually is the single most cost-effective periodic item in an office contract. Entrance matting and the first few metres of carpet darken long before the rest of the floor, so cleaning the whole area every time is money wasted.

Writing a specification that works

Six things turn a checklist into a contract you can enforce:

1. Task and frequency, separately. Not "clean washrooms" but "washroom suite cleaned, sanitised and descaled: daily". Frequency is the half that gets forgotten and the half that gets dropped.
2. Area-by-area, not building-wide. Reception, open plan, meeting rooms, kitchen, washrooms, circulation, stairs. Each gets its own list, because each needs a different one.
3. Name who supplies consumables. Soap, paper, bin liners. Running out of hand towels on a Friday is a cleaning failure as far as your staff are concerned, whoever technically bought them.
4. Define access and hours. Who holds keys, what the alarm procedure is, what time cleaning happens, and who is called if the alarm goes off.
5. Set a review cadence. Monthly for the first quarter, then quarterly. Written down, so it happens without anyone having to raise a problem first.
6. Attach the compliance pack. Insurance certificates, COSHH data sheets for every product used on site, risk assessment and method statement. Ask for it at tender stage, not after an incident.

One more thing worth building in: hybrid working. If your office is full Tuesday to Thursday and quiet Monday and Friday, five identical visits are waste. A heavier mid-week specification with lighter ends costs less and matches reality.

How to check it is actually being done

Three mechanisms, in increasing order of usefulness.

Signed task sheets are the weakest. They prove someone wrote something, not that it happened. Useful as a record, worthless as assurance. A monthly supervisor audit scored against the specification is far better, especially if the score and the comments come to you in writing. The value is not the number, it is that problems surface before you have to notice them yourself. A named account manager with a direct number is the one that actually matters. Almost every cleaning problem is a five-minute conversation if you can reach a decision-maker, and a six-week saga if you are filing tickets. When you are choosing a contractor, ask who you will ring and what their response time is: then test it before you sign.

Our own office cleaning in Plymouth runs on exactly these three: a written specification from a free site survey, a monthly audit sent to you, and one named person to call.
