Winter office cleaning checklist: flu season, wet floors and grit
Why winter is harder on offices
Winter puts more pressure on office cleaning than any other season. Wet shoes carry water, mud and road grit into reception areas, lifts and corridors. Grit scratches hard floors and grinds into carpet, while wet floors are a slip risk. At the same time, coughs and colds spread around desks, kitchens and meeting rooms, and staff spend more time indoors with windows closed.
Entrances and floors
Most of the dirt that ends up on office carpets comes in on shoes. Good entrance matting catches it before it spreads, but only if it is long enough and kept clean itself.
- Use matting long enough for several steps, both outside and inside the door
- Vacuum or change entrance mats daily in wet weather
- Mop hard floors at entrances more often, and use wet floor signs
- Dry mop reception areas during the day if they get heavy footfall
- Remove salt and grit residue from hard floors before it etches the finish
- Check lift floors and stairs, which collect water from umbrellas and shoes
Slips are one of the most common causes of workplace injuries in the UK, and wet entrances are a classic cause. Rental matting services that swap mats regularly are worth considering for busy buildings.
Cold and flu season hygiene
Viruses spread through hands and touched surfaces as well as the air. Cleaning cannot stop every bug, but it reduces how long germs survive on shared surfaces.
| Area | Winter adjustment |
|---|---|
| Door handles, push plates and lift buttons | Clean and disinfect on every visit |
| Kitchen taps, kettles and fridge handles | Clean and disinfect on every visit |
| Shared desks, phones and meeting room tables | Wipe on every visit |
| Washrooms | Check soap and towels more often, add a midday restock |
| Hand sanitiser stations | Refill and wipe regularly |
Disinfectants work best on surfaces that are already clean, and they need their stated contact time. A quick spray and wipe often removes the product before it has worked.
Heating, dust and air
- Dust radiators and heater covers before they are turned on for the season
- Vacuum vents and grilles, which blow dust around once heating is running
- Check that washroom and kitchen extract fans are clean and working
- Keep windows and sills clean, as condensation encourages mould in corners
The Christmas deep clean
The office is often quietest between Christmas and New Year, which makes it the best time for jobs that are disruptive during normal weeks. Book early, because this is a popular slot.
- Hot water extraction carpet cleaning, with time to dry before staff return
- Hard floor machine scrub and polish
- Deep clean of kitchens, fridges and appliances
- Washroom descale
- High-level dusting and vent cleaning
- Clearing out stationery cupboards and storage areas before the new year
After the office party
If your party is held in the office, book an extra clean for the following morning. Food, drinks and glitter can stain carpets if left over a weekend, so ask for spot treatment of stains as soon as possible.
Snow, ice and outside areas
Employers and occupiers have a duty to keep routes to and from the building reasonably safe, and that includes paths and car parks they control in icy weather. In shared buildings, the landlord or managing agent usually handles external areas, so check who is responsible before the first frost.
- Agree who grits paths, steps and car parks, and when
- Keep a supply of grit or salt and a scoop near the entrance
- Grit early, before ice forms, rather than after people have slipped
- Clear snow from the main entrance route first
- Put extra matting inside the door on snowy days
- Check that external lighting works, as dark mornings and evenings add to the risk
Gritting is not normally part of an internal cleaning contract, but it can sometimes be added for early morning visits. If it is, write it into the specification with a clear start time, because ice that forms at 6am is no help if the cleaner arrives at 8am.
Salt and grit trodden indoors leave a white residue on hard floors and can dull or etch some finishes. A neutral floor cleaner used regularly through winter removes it before it does damage, and a machine scrub in spring brings floors back to their best.
Frequently asked questions
How often should entrance mats be cleaned in winter?
In wet weather, entrance mats in busy offices should be vacuumed daily and swapped or deep cleaned regularly, as a saturated mat stops catching dirt and water. Rental mat services typically swap mats weekly or fortnightly, and more often for very busy entrances. Clean mats protect the carpets beyond them, and a mat that is curling or rucked should be replaced, as it becomes a trip hazard itself.
Does extra cleaning reduce sickness in the office?
Regular cleaning of shared touch points, kitchens and washrooms reduces the number of germs on surfaces, and good handwashing facilities help people keep hands clean. It will not stop every cold or flu, as viruses also spread through the air, but it is a sensible part of reducing spread during winter.
When is the best time to clean office carpets in winter?
The Christmas and New Year break is ideal because carpets have time to dry and staff are not walking on them. Otherwise, plan extraction cleans for a Friday evening or weekend. Cleaning after the worst of the winter weather, around early spring, also removes ground-in grit before it wears the fibres.
