How Much Does Office Cleaning Cost in London in 2026? (Guide)

Office cleaning costs in London in 2026 typically vary from £19–£35 per hour, depending on what you need and where you're based. For a small office (around 500 sq ft) cleaned three times a week, expect to pay roughly £320–£480 a month. Central London locations usually run 10–20% higher than outer boroughs, and out-of-hours cleaning adds another £3–£8 an hour. Most contracts run for 3–12 months with a 1–3 month notice period. The exact price depends on your office size, how often you need cleaning, and what's included — we'll break all of that down below.

What affects the cost of office cleaning in London?

A handful of factors push your quote up or down. Here's what actually matters:

Cleaning frequency. Daily cleaning costs more overall than three-times-a-week cleaning, but the per-visit rate often drops slightly because you're committing to more regular work.

Square footage. This is the big one. Cleaners price by how much floor space they need to cover and how long that realistically takes.

Sector. A medical or healthcare setting needs stricter hygiene standards, specialist products, and sometimes additional training — so it costs more than a standard office.

Time of day. Daytime cleaning is cheaper. Out-of-hours cleaning (early morning, evening, or overnight) usually adds £3–£8 per hour because of unsociable hours pay.

Location. Central London postcodes typically carry a 10–20% premium over outer London, mainly down to staff travel costs and wages.

Staff headcount. More people in the building usually means more rubbish, more washroom use, and more general wear — which affects time on site.

Specialist areas. Washrooms, kitchens, and break-out areas take longer to clean properly and are often priced separately from general office space.

Hourly vs monthly contract pricing

Most cleaning companies quote either an hourly rate or a fixed monthly contract price. Hourly rates give you flexibility; monthly contracts give you predictability and are usually a bit cheaper overall.

Here's a rough guide based on office size:

Office size	Typical cleaning frequency	Estimated monthly cost
Small (approx. 500 sq ft)	3x per week	£320–£480
Medium (approx. 2,000 sq ft)	5x per week	£900–£1,400
Large (approx. 5,000+ sq ft)	Daily	£2,200–£3,500+

These are general estimates — your actual quote will depend on the specifics of your building, location, and what's included.

What's typically included in an office cleaning contract?

A standard contract usually covers:

• Hoovering and mopping of all floor areas

• Emptying bins and replacing liners

• Dusting desks, surfaces, and communal areas

• Cleaning and restocking washrooms

• Kitchen and break-out area cleaning

• Wiping down high-touch points (door handles, light switches, lift buttons)

• Internal glass and partition cleaning

What costs extra?

Some jobs sit outside the standard contract and get quoted separately:

• Deep cleans — periodic intensive cleans, often quarterly or annually

• Window cleaning (external) — usually a separate visit and supplier

• Specialist floor care — carpet shampooing, hard floor stripping and sealing

• Consumables — hand soap, paper towels, and toilet roll are sometimes billed as a top-up rather than included in the base price

Always check whether consumables are included before comparing two quotes side by side — it's one of the easiest ways quotes look different when they're not.

How to get an accurate quote

Before you contact cleaning companies, have this ready:

• Floor plan or approximate square footage

• Number of staff/desks and how many days a week the office is occupied

• Preferred cleaning frequency (daily, 3x/week, etc.)

• Preferred cleaning time (daytime vs out-of-hours)

• Any specialist areas (kitchen, washrooms, server rooms)

• Current contract length and notice period, if you're switching providers

Having this to hand means you'll get a like-for-like quote rather than a rough guess — and you'll be able to compare providers fairly.
