How Long Cleaning Takes by Business Type

The honest answer to "how long will it take to clean my premises?" is that it depends far less on floor area than most people assume, and far more on what you actually do in the building. We clean a 2,000 square foot solicitor's office and a 2,000 square foot dental practice in the same week, and the surgery takes us nearly twice as long. Same square footage, completely different clock. So rather than give you one blanket figure, we have broken the timings down by business type, because a call centre, a care home and a hair salon each carry their own cleaning arithmetic. Below is what we actually budget on the job sheet for each sector, and why the numbers land where they do.

Why the sector matters more than the square footage

Three things drive cleaning time, and none of them is the size printed on the lease. The first is touchpoint density: how many desks, handles, taps, keypads and shared surfaces a person has to physically wipe. An open-plan design studio with 30 hot desks has fewer fixed touchpoints than a GP surgery with 8 consulting rooms, because the surgery multiplies sinks, couches, bins and door handles behind every door. The second is the hygiene standard the sector is held to. Wiping a desk and disinfecting a clinical surface to a documented protocol are not the same task, and the second one cannot be rushed. The third is disruption: whether we can work through an empty building at 6pm or have to move around staff, customers and stock in real time.

Put those three together and you get wild swings. A retail unit clears fast because it is mostly floor. A veterinary practice crawls because every room is a potential contamination zone. Understanding your own sector's profile is the difference between a schedule that holds and one that quietly overruns every night. Our broader commercial cleaning planning always starts with this sector question before anyone measures a floor.

Standard offices: fast, predictable, floor-led

A conventional office is the easiest sector to time because so much of it is repetitive. Bins, desks, kitchen, washrooms, floors, done. For a typical professional office of around 3,000 square feet, 25 to 30 workstations, two meeting rooms, a kitchen and two washrooms, we schedule a single cleaner for roughly two to two and a half hours on a nightly maintenance visit. The bulk of that time is not the desks, it is the washrooms and the kitchen, which between them eat close to half the shift.

Open-plan offices come in noticeably quicker than cellular ones. A team sat in one big room lets us run a wide vacuum in long straight passes and wipe a whole bank of desks without opening a single door. Break that same floor into 20 private offices and you add door handling, individual bins and awkward corners, which can stretch the same area by 30 to 40 minutes. If your office runs to a fuller specification, our office cleaning visits are timed to the layout rather than a flat rate, which is why two offices of identical size can carry different nightly windows.

Dental, medical and veterinary: the slow sectors, and rightly so

Clinical premises are where the clock stretches most, and there is no shortcut worth taking. In a dental practice, each surgery has to be cleaned and disinfected as a discrete zone: the chair, the bracket table, the spittoon, the light handles, the cabinetry, the floor, the clinical waste. We budget 20 to 25 minutes per surgery on its own, before we have touched reception, the decontamination room or the washrooms. A four-surgery practice therefore runs closer to two and a half hours than the 90 minutes its floor area would suggest. The same logic drives our specialist dental practice cleaning timings.

Veterinary premises are slower still. You are dealing with animal hair, kennels, consult rooms, a prep area and the ever-present risk of cross-contamination between patients. Floors need proper wet cleaning rather than a quick mop, and consult rooms are disinfected between the last appointment and the next morning. A modest two-vet practice can easily absorb two hours of careful work. GP surgeries, pharmacies and physiotherapy clinics sit on the same clinical curve: more rooms, more sinks, more documented protocol, more time. The rule of thumb we give clients is simple. If your sector is regulated for hygiene, budget roughly double the time you would for the same footprint of ordinary office.

Retail, showrooms and gyms: big floors, light touchpoints

Retail is the opposite profile to clinical. A shop floor is mostly, well, floor. Once you have vacuumed or scrubbed it, cleaned the glass, wiped the counter and serviced the customer and staff toilets, you are largely finished. A standard high-street unit of 1,500 to 2,000 square feet often comes in under an hour for a nightly maintenance clean, because the touchpoint count is low even though the area feels large. The two things that add time are glass and fitting rooms: a showroom with a lot of display glazing, or a fashion store with 12 changing cubicles, will push the number up because both need detailed attention.

Gyms follow the retail pattern of big open floors but add a sweat and equipment factor. Machines, mats, free weights and studio floors all need wiping down, and the changing rooms and showers are effectively a wet-washroom job at scale. A mid-sized gym still moves quickly across the main floor but loses real time in the wet areas. Car showrooms clean fast on the sales floor and slowly on the glass. If your premises are floor-led rather than room-led, the good news is that our retail cleaning visits are usually among the shortest per square foot of any sector we handle.

Hospitality and care: the deep, unglamorous end

Pubs, restaurants and their kitchens are a category of their own. The front of house is quick, similar to retail, but the kitchen is where hours disappear. Degreasing surfaces, cleaning behind and under equipment, servicing extraction and getting floors genuinely non-slip is slow, physical work that has to meet food-safety standards. A pub with a full commercial kitchen can carry a front-of-house clean of under an hour and a kitchen deep clean that runs to several hours on its own, which is why the two are usually scheduled separately rather than crammed into one visit.

Care homes are the marathon sector. They are occupied 24 hours a day, so we can never clear the building and work freely. Every resident room, communal lounge, dining area and assisted bathroom needs attention, infection control is non-negotiable, and we work around residents, staff and mealtimes throughout. A modest 40-bed home is not a two-hour job under any circumstances; it is a daily programme measured in staff-hours across a team, with certain areas cleaned multiple times a day. The sector combines the room-density of a clinic with the round-the-clock occupancy of a hotel, which is the slowest possible combination.

How to shorten the clock in any sector

Whatever your business type, a few things reliably pull the timing down without cutting corners. Clearing desks and surfaces at the end of the day is the single biggest gain in an office, because we clean surfaces, not the clutter on top of them. Letting us work outside your opening hours removes the disruption factor entirely and can shave a third off the time for any occupied premises. Keeping consumables stocked and access straightforward, so nobody is hunting for keys or a cupboard, protects the schedule. And a fixed, well-mapped routine matters more than most owners expect: once a team knows your building, the same clean gets quicker and more consistent because they are no longer working it out as they go.

The other lever is matching frequency to your sector's soil rate. A quiet accountancy office genuinely holds up on three visits a week. A busy gym or a food premises does not, and stretching the frequency just means each visit has to work harder and longer to claw back the build-up. If you are not sure where your premises sit, that is exactly the conversation to have before signing anything. Call us on 0800 069 9055 or email [email protected] and we will walk your building, count the real touchpoints and give you an honest per-visit window rather than a floor-area guess.

Frequently asked questions

Why does my dental practice take longer to clean than a bigger office?

Because time follows touchpoints and hygiene standard, not floor area. A dental surgery multiplies sinks, clinical surfaces and door handles behind every treatment-room door, and each one has to be disinfected to a protocol rather than simply wiped. That easily doubles the time of a larger but simpler open-plan office.

What is the quickest type of business to clean?

Floor-led premises with low touchpoint density, typically retail units and showrooms. Once the floor, glass, counter and toilets are done there is little left, so a standard shop often comes in under an hour for a maintenance clean despite feeling large.

How long does a pub kitchen take compared to the bar area?

The bar and front of house behave like retail and clean quickly, often under an hour. The commercial kitchen is a different job entirely: degreasing, cleaning behind equipment and getting floors safe can run to several hours, so we usually schedule kitchen deep cleans separately from the routine visit.

Why can't you give one price-per-square-foot for every sector?

Because two premises of identical size can differ by double in cleaning time depending on what happens inside them. A flat per-square-foot rate would overcharge a simple office and badly undercharge a clinic or a food premises, so we time each sector to its actual workload.

Does cleaning during opening hours make it take longer?

Yes, noticeably. Working around staff, customers and stock adds navigation time and interrupts equipment use. For most occupied premises, moving the clean outside opening hours removes that friction and can reduce the visit time by around a third.

How can I make my premises quicker to clean?

Clear surfaces at the end of the day, keep access and keys straightforward, keep consumables stocked, and let a consistent team learn your building. Matching your visit frequency to how quickly your sector gets dirty also stops each clean having to work harder to catch up.
