How often should an office be deep cleaned?

Many offices schedule a deep clean every three to six months. Busy offices, kitchens and washrooms may need deeper cleaning more often.

How long does an office deep clean take?

It depends on the size of the office, the flooring and how much furniture needs moving. Ask for an estimate after a site visit.

Is a deep clean different from regular office cleaning?

Yes. Regular cleaning covers routine tasks. A deep clean reaches areas and dirt that routine visits do not, such as under furniture and high-level surfaces.

Regular cleaning keeps an office tidy day to day, but some dirt builds up slowly in places routine visits do not reach. An office deep clean resets the whole space.

This guide explains what an office deep clean includes, how often to schedule one and how to plan it with minimal disruption.

What an office deep clean includes

Moving furniture to clean underneath and behind it.
Deep cleaning carpets and machine-cleaning hard floors.
High-level dusting of lights, vents and the tops of cupboards.
Thorough cleaning of kitchens, appliances and washrooms, including grout and fittings.
Cleaning chairs, upholstery, blinds and internal glass.

How often to deep clean

There is no single legal frequency. Many offices find a deep clean every three to six months works well, with some tasks, such as kitchen appliances, done monthly. The right schedule depends on:

how many people use the office each day
whether there is a busy kitchen or customer-facing area
the type of flooring and furniture
how thorough your regular cleaning is

Signs you need a deep clean sooner

Stains or dull patches on carpets and floors.
Dust visible on vents, lights or high shelves.
Lingering smells in kitchens or washrooms.
After building work, an office move or a long closure.

Planning a deep clean

Agree a date when the office is quiet, such as a weekend.
Ask staff to clear desks and personal items.
Confirm access, alarms and any areas that are off limits.
Agree who supplies specialist equipment, such as carpet machines.
Check work at height is planned safely. See HSE guidance on working at height (opens in a new tab).

Add it to your cleaning plan

Put deep-clean tasks and their frequency into your office cleaning checklist, so they are priced and planned from the start rather than added as a surprise.
