The 2026 Guide to Commercial Cleaning Contracts: What UK Businesses Need to Know

By Zach Cleaning ·

The Post-Pandemic Commercial Cleaning Landscape

Commercial cleaning in the UK has transformed since 2020. Clients now demand transparent auditing, eco-compliance, and verifiable hygiene standards alongside traditional cleaning. The British Institute of Cleaning Science reports that 73% of commercial clients now ask about environmental credentials before awarding a contract.

For businesses in Leicester and the East Midlands — from offices at Grove Park to retail units in the Highcross — here is what to look for in a commercial cleaning partner in 2026.

1. Insurance: The Non-Negotiable Minimum

Your cleaner should carry public liability insurance of at least £5 million. This is industry-standard and protects your business if a cleaner damages property or a member of the public is injured. Ask to see the certificate — not just the policy number. Also check for employer's liability insurance (legally required if the cleaning company employs staff) and, if they handle keys or alarm codes, key-holding insurance.

2. DBS Checks: Who Is in Your Building After Hours?

Most commercial cleaning happens outside business hours — early mornings, evenings, or weekends. Every member of staff who enters your premises should be DBS-checked (Disclosure and Barring Service). A basic DBS check costs £18 and takes 48 hours to process — there is no excuse for a cleaning company not to run them. Ask specifically: "Are all operatives assigned to our contract DBS-checked?"

3. Pricing Models: What You're Really Paying For

Commercial cleaning is typically priced in one of three ways:

  • Per square foot: common for offices and retail. Currently £0.08–£0.25/sq ft per visit in the East Midlands, depending on frequency and specification.
  • Per hour: common for deep cleans and one-off work. Rates in Leicester range from £18–£28/hour for general cleaning, with specialist services (window cleaning, carpet extraction) priced separately.
  • Fixed monthly contract: best for ongoing work. Includes regular cleans plus periodic deep cleans. Look for contracts that specify exactly what is included — "cleaning" is not a specification.

4. The Specification Sheet: Your Single Most Important Document

A proper cleaning contract includes a room-by-room specification detailing exactly what will be cleaned, how often, and with what products. Example: "Gents' toilets, first floor: Sanitise all urinals, toilets, sinks, taps, and splashbacks. Replenish soap, toilet paper, and hand towels. Damp-mop floor with disinfectant. Empty sanitary bins. Frequency: daily, Monday–Friday."

Vague language like "clean the office" is a red flag. If it's not in the spec, it won't be done.

5. Eco-Compliance and Waste Handling

From 2025, UK businesses must separate recyclable waste streams under the Simpler Recycling legislation. Your cleaning contract should align with this — cleaners should know which bins to use for glass, paper, plastic, food waste, and general waste. Ask about the products used: are they biodegradable? Do they meet EU Ecolabel or equivalent standards? Your business's own ESG reporting may depend on this.

6. Audit and Quality Control

A reputable cleaning company will welcome audits. Ask: "How often do you inspect the quality of your own work?" The answer should be at least monthly, with a documented audit trail you can review. Many companies now use apps that log attendance, completion times, and any issues flagged — ask to see a sample report.

Frequently Asked Questions

What's the minimum contract length for commercial cleaning?

Most companies offer a 3-month trial period followed by a rolling monthly contract. Avoid contracts that lock you in for 12+ months without a break clause. A 30-day notice period is standard.

Do I need to provide cleaning equipment and products?

Most professional companies bring their own — including colour-coded cloths (red for toilets, blue for general areas, green for kitchens) to prevent cross-contamination. This is a BICSc standard. If a company asks you to supply everything, treat it as a red flag.

Can I claim commercial cleaning as a business expense?

Yes. Commercial cleaning is a deductible business expense for UK tax purposes. Keep all invoices — HMRC may ask for them. If the cleaning is part of a serviced office or co-working arrangement, it is typically bundled into the service charge rather than separately invoiced.
