What Are Cleaning Tenders?
A cleaning tender is a formal invitation from an organisation seeking a professional cleaning company to provide services.
Instead of requesting quotes from a handful of businesses, larger organisations advertise opportunities publicly and invite suppliers to compete.
After reviewing submitted proposals, they award the contract to the company that demonstrates the best value not necessarily the cheapest price.
Cleaning tenders are common across both the public and private sectors.
Examples include:
- Office cleaning
- School cleaning
- NHS and healthcare cleaning
- University cleaning
- Housing association cleaning
- Retail cleaning
- Warehouse cleaning
- Industrial cleaning
- Window cleaning
- Specialist deep cleaning
- Facilities management contracts
Many contracts last between one and five years, providing predictable income and business stability.
Why Cleaning Tenders Matter
Winning a cleaning contract offers benefits beyond immediate revenue.
Successful contracts can help your business:
- Build a steady monthly income
- Expand your workforce
- Invest in better equipment
- Improve cash flow
- Increase credibility
- Win larger contracts in the future
Many public sector organisations also renew contracts with reliable suppliers, making tenders an excellent long-term growth strategy.

Understanding the Tender Process
Many businesses think tenders are overly complicated.
In reality, most follow the same process.
Step 1: Opportunity Published
The buyer advertises the contract.
Step 2: Download Tender Documents
You’ll receive:
- Specification
- Pricing schedule
- Evaluation criteria
- Terms and conditions
Read everything carefully.
Step 3: Ask Clarification Questions
If anything is unclear, ask before the deadline.
Never make assumptions.
Step 4: Prepare Your Submission
This usually includes:
- Company profile
- Method statements
- Risk assessments
- Pricing
- References
- Policies
- Insurance documents
Step 5: Evaluation
Buyers score submissions based on quality and price.
Many contracts are weighted around:
- 60% Quality
- 40% Price
The exact weighting varies by buyer.
Step 6: Contract Award
Successful suppliers begin mobilisation before service delivery.
Common Reasons Cleaning Businesses Lose Tenders
Avoid these common mistakes.
Submitting Late
Deadlines are strict.
Late submissions are usually rejected automatically.
Ignoring Evaluation Criteria
If quality carries more marks than price, spend time strengthening your quality responses.
Pricing Too Low
Unsustainably low pricing often raises concerns.
Buyers want value—not unrealistic costs.
Weak Evidence
Don’t simply claim you’re reliable.
Prove it.
Use examples.
Poor Presentation

Professional submissions create confidence.
