What Is a Commercial Deep Clean?
A commercial deep clean is an intensive, top-to-bottom clean of business premises that removes the build-up routine cleaning leaves behind. Regular cleaning keeps surfaces tidy day to day; a deep clean goes further, reaching high-level areas, moving light furniture, degreasing kitchens, descaling washrooms and machine-cleaning floors.
Most businesses need a deep clean once or twice a year, or once a quarter in busy premises. Many also book one at a turning point: moving in, moving out, after building work, before an audit or inspection, or when a new cleaning contract starts and the premises need resetting to a known standard.
What Our Deep Cleaning Includes
Every deep clean is planned from a site visit and written up as a task list, so you know exactly which areas will be covered and to what level.
Kitchens and Break Areas
Worktops, cupboard fronts, splashbacks and appliance exteriors are degreased, sinks and taps are descaled, and microwaves, fridges and dishwashers are cleaned inside where agreed. Floors are scrubbed, including edges and the space under units.
Washrooms
Toilets, urinals, basins and taps are descaled, cubicle partitions and walls are washed, grout is scrubbed and floors are deep cleaned. Dispensers and hand dryers are cleaned inside and out. For ongoing standards, see our washroom hygiene service.
High-Level Areas and Touch Points
Ledges, vents, light diffusers, door frames and the tops of cupboards are dusted, and touch points such as handles, switches, handrails and lift buttons are cleaned and sanitised.
Floors
Hard floors are machine scrubbed and carpets are deep vacuumed, with specialist floor care such as carpet extraction available through our commercial floor cleaning service.
Deep Clean Checklist by Premises Type
The focus of a deep clean changes with the type of premises, so we tailor the checklist to how your building is used.
| Premises | Deep clean focus | Typical cycle |
|---|---|---|
| Offices | Kitchens, washrooms, carpets, desk touch points, high-level dust | Quarterly or twice a year |
| Warehouses | Full floor scrub, racking bases, loading bays, welfare blocks | Quarterly |
| Shops and showrooms | Floors, glass, displays, fitting rooms, stockrooms | Quarterly or before seasons |
| Industrial units | Degreasing, production floors, machine surrounds, welfare areas | During shutdowns |
| Clinics and gyms | Washrooms, changing areas, touch points, floors | Quarterly |
For office and warehouse premises, our guides on what commercial cleaning normally includes and the commercial floor cleaning guide show where routine cleaning ends and deep cleaning begins.
When Businesses Book a Deep Clean
Businesses in Bexley usually book a commercial deep clean at one of these moments:
- Moving in to new offices, a shop or an industrial unit, so you start in a clean building.
- Moving out at the end of a lease. See our commercial end-of-lease cleaning.
- After refurbishment or building work, when dust settles on every surface.
- Before an audit, inspection or visit from a client, head office or landlord.
- Seasonal resets, such as before peak trading or after a busy period.
- On a periodic programme, quarterly or twice a year, alongside regular office cleaning in Bexley or scheduled warehouse cleaning.
Post-Refurbishment and Builders' Cleans
A post-refurbishment clean removes the fine dust and residue building work leaves behind, so your premises are ready to use.
What It Covers
Dust is removed from every surface, including high ledges, vents, skirting and inside cupboards. Paint spots, adhesive and plaster marks are cleaned from floors, glass and fittings where possible, and floors are vacuumed and scrubbed more than once to lift settled dust.
When to Book It
Book the clean once trades have finished and before furniture and stock go back in. We visit the site first to check the condition and agree what will be cleaned and what needs a specialist.
How Long Does a Commercial Deep Clean Take?
Most commercial deep cleans take between one evening and a full weekend, depending on the size of the premises, the level of build-up and how much floor care is involved.
A small office or shop can often be deep cleaned in a single evening by a small team. Larger offices, warehouses and industrial units are usually split over a weekend or several evenings, area by area, so the business can keep running. We give you the planned timings with your quote, and we always finish an area before moving on, so nothing is left half done when your staff return.

How Much Does a Commercial Deep Clean Cost?
Commercial deep cleaning is priced per clean, based on the size of the premises, how much build-up there is and the specialist work involved. Because condition varies so much, we always visit before quoting.
| Factor | Why it changes the price |
|---|---|
| Size and number of rooms | More area and more separate rooms take more time |
| Level of build-up | Heavy grease, limescale or construction dust takes longer to remove |
| Kitchens and washrooms | The most detailed parts of any deep clean |
| High-level access | Tall ceilings and ledges need access equipment |
| Floor care | Machine scrubbing and carpet cleaning are priced as items |
| Timing | Short windows may need a larger team |
Booking deep cleans as a periodic programme means each visit starts from a better condition, which usually keeps the cost per clean down.
