How to Quote Commercial Office Cleaning Contracts in the UK (2027 Guide)

Expanding from domestic home cleaning into recurring commercial contracts is the most reliable way to scale a cleaning company in the United Kingdom. While domestic cleans are vulnerable to holiday cancellations and weekly schedule shifts, commercial contracts provide predictable, recurring monthly revenue and higher contract values.

However, quoting commercial properties requires a rigorous pricing formula. Underbidding a commercial tender can trap your business in an unprofitable contract for 12 months, while overbidding means losing out to local competitors.

This guide walks you through the step-by-step formula for calculating commercial cleaning quotes, conducting site surveys, and formatting professional B2B proposals in 2027.

Step 1: The Commercial Site Survey Walkthrough

Never quote a commercial office, clinic, or showroom over the phone without visiting the site. During your walkthrough, inspect the following key factors:

• Total Floor Area & Surface Types: Note the split between carpeted offices, hard floors, and ceramic tiles in bathrooms.
• Bathroom Count & Daily Footfall: A 50-person office requires significantly more sanitation time than a 10-person agency.
• Kitchenettes & Breakrooms: Inspect microwaves, fridges, sinks, and dishwasher loading routines.
• High-Frequency Touchpoints: Desks, door handles, handrails, lift buttons, and keypad entry systems.
• Access Logistics: Key safe codes, alarm fobs, out-of-hours access, and waste bin disposal locations.

Step 2: Estimating Cleaning Hours

In standard commercial office environments, an experienced commercial cleaner cleans between 2,500 and 3,500 square feet per hour under standard maintenance conditions. If the office includes extensive bathrooms, high kitchen usage, or heavy glass partitioning, adjust production rates down to 2,000 square feet per hour.

Step 3: Calculating Your Price

Your hourly price must leave a healthy gross margin above your staff wage expenses. In 2027, the realistic breakdown for a profitable UK commercial cleaning charge rate looks like this:

• Cleaner Pay: £12.20 to £13.50 per hour.
• Statutory Employment Overheads: Employer National Insurance, auto-enrolment workplace pension, and statutory holiday accrual (approx. 20% to 25% on top of wage).
• Business Overheads & Margin: Insurance, cleaning chemicals, staff management, and company profit margin.
• Target Client Price: £19.00 to £26.00 per hour across England, Wales, Scotland, and Northern Ireland (or £24.00 to £32.00 in Central London).

Step 4: Handling Bathroom Consumables & Cleaning Supplies

Commercial clients often ask cleaning contractors to supply bathroom consumables: toilet rolls, paper hand towels, liquid hand soap, and bin liners. You can handle this in two ways:

• Recharged at Cost + 20% Handling Margin: Invoice consumables monthly based on exact replenishment quantities.
• Included in Fixed Monthly Retainer: Bundle consumables into the monthly invoice based on average monthly usage.

Structuring a Winning B2B Commercial Quote

Commercial office managers and operations directors expect professional, itemised proposals. Ensure your quote includes:

• Clear Scope of Work: Frequency of visits (e.g. 3 evenings per week, Monday/Wednesday/Friday, 2 hours per visit).
• Fixed Monthly Billing: 6 hours/week × 52 weeks ÷ 12 months = 26 hours/month. At £22/hr, the fixed monthly retainer is £572 + VAT.
• HMRC VAT Compliance: Itemised net, VAT rate, and total gross amounts.
