How Much Does Commercial Cleaning Cost in the UK? (2025 Guide)

If you're shopping for a commercial cleaning contract, the first question is almost always the same: how much should this cost? The honest answer is that there is no single number — and any cleaning company that quotes you a price without seeing your premises is either guessing or selling you something they can't deliver.

This guide walks through what actually drives commercial cleaning prices in the UK in 2025, typical ranges to expect, and how to get a quote you can trust.

What affects commercial cleaning pricing?

1. Size of your premises

The single biggest factor. Cleaning a 1,200 sq ft serviced office is fundamentally different from cleaning a 25,000 sq ft multi-floor building. Most contractors price either per square foot or on an estimated time-on-site basis derived from square footage and complexity.

2. Frequency of service

Daily cleaning, three-times-a-week, weekly or one-off — frequency dramatically changes both the hourly cost and the total monthly cost. Daily contracts often have a lower hourly rate because the work is regular and predictable. One-offs cost more per hour because there's mobilisation, briefing and quality risk.

3. Type of premises

An office cleaning contract is not priced the same as a healthcare contract or an industrial deep clean. Healthcare requires IPC-trained staff and clinical-grade products. Industrial cleans need specialist equipment. Schools require DBS-checked staff. Each of these affects pricing.

4. Service mix

Daily cleans alone are one price. Add internal window cleaning, periodic deep cleans, washroom consumables and waste services and the contract value rises — but the per-line cost typically improves.

5. Location

Central London is more expensive than Brighton. Brighton is more expensive than rural Sussex. Travel time, parking, congestion charges and London weighting on wages all affect what a contract has to cost to be sustainable.

Typical price ranges

As a rough guide for 2025:

• Small office (under 1,000 sq ft), 3x weekly: £350–£600 per month
• Medium office (5,000 sq ft), daily: £1,800–£3,200 per month
• Larger office (15,000 sq ft), daily: £4,500–£8,500 per month
• School, term-time daily plus holiday deep cleans: heavily dependent on size and access
• Industrial / warehouse: typically priced separately by zone and frequency

What should be included?

A genuine contract should specify: scope of works, hours on site, named team or staffing model, frequency schedule, consumables (included or excluded), washroom servicing, quality reporting cadence, insurance details and notice terms. If a quote is vague on any of these, ask before you sign.

How to get an accurate quote

Insist on a site survey. Any reputable contractor will visit your premises before quoting — not because they're being thorough for the sake of it, but because pricing without seeing the site leads to over-promising and under-delivering.

Why cheapest isn't always best

Cleaning is a labour-cost business. If one quote is significantly lower than the others, it almost always means one of three things: less time on site, lower-paid (and therefore higher-turnover) staff, or assumptions that won't survive contract reality. The contracts that fail tend to be the ones priced too low to deliver what was promised.

FAQ

Should I expect a fixed price or hourly rate? Most contracts are fixed monthly fees against a defined scope. Ad-hoc work is usually hourly.

How often should prices be reviewed? Annually, with a clear mechanism in the contract.

What's a fair notice period? Usually 1–3 months either way for ongoing contracts.
