Why are many school cleaning tenders out of date?

Many tenders are copied forward from older documents. Common signs are references to BS 5750 or ISO 9002 (both replaced decades ago), procurement rules that no longer apply to new procurements, no KPIs or Red/Amber/Green thresholds, no test of how absence is covered, and safeguarding checks that do not mention relief or agency staff.

How many cleaning hours does a school need?

It depends mainly on the floor area, the type of school, the floor finishes and the standard required. As a guide, the School Cleaning Tender Assistant and the Cleaning Hours Estimator use productivity rates by school type to give a weekly figure from your floor area. Use it as a benchmark to test whether bidders' staffing and prices are realistic.

How can I find my school's floor area?

The most accurate source is your site plans or CAD drawings. Many schools also have a published Display Energy Certificate, which records the gross floor area. If neither is to hand, the Department for Education's area guidelines (BB103 for mainstream schools and BB104 for special schools) give a recommended range from pupil numbers. The Tender Assistant uses all three.

Is the School Cleaning Tender Assistant free, and do I need to sign up?

It is free and there is no sign-up or email needed. Enter your school's postcode and pick what matters most. The Word tender document is built on your own device, and the tool is neutral: it does not favour any provider.

Why does management support matter in a school cleaning tender?

Who the manager is, where they are based and how many other contracts they oversee often determines whether issues are caught early or allowed to drift. A credible bidder should be able to answer these questions specifically, not generically.

What are red flags in a school cleaning tender response?

Red flags are practical warning signs: vague answers on absence cover, no named local manager, no described quality audit process, KPIs without targets, or reporting that is not clearly defined. They are prompts to probe further, not a determination that a bidder is unsuitable.

Does the Tender Assistant replace procurement or legal advice?

No. It helps schools and trusts work through the right areas in a structured way. Use it alongside your own procurement processes, policies and professional advice, and have the final documents reviewed before issue.

Why It Matters

A good cleaning tender tests more than headline price

The questions that tend to determine whether a school cleaning contract actually works day to day are rarely the ones about price. They are the ones about how the service is managed, supervised, staffed and monitored once the contract starts.

This tool is designed to help schools think through these areas in a structured way, without telling you what you must do, and without making promises about outcomes. Every school and trust is different.

Before running the assistant, you may find it useful to read our guide on school cleaning procurement and tendering, covering how proposals are evaluated and what makes a service operationally realistic.

Start the assistant

Local management support: where the manager is based, how many contracts they oversee, and how quickly they can respond

Safeguarding and DBS management, including agency and relief staff vetting

Staffing resilience: how absence is covered without simply extending existing staff hours

Quality monitoring and audit: frequency, format and whether audits are genuinely independent

BICSc or equivalent cleaning methodology, and whether it is maintained after mobilisation

Reporting and KPIs: what information the school receives and how often

Mobilisation and TUPE readiness, where this applies

Financial standing and contract resilience, particularly for longer-term contracts

Key Areas

The areas this tool focuses on

Management Support

Who is the manager? Where are they based? How many other contracts do they oversee? These questions often determine whether issues are caught early or allowed to drift.

Safeguarding

Schools have specific safeguarding responsibilities. A credible answer goes beyond having a policy; it describes how DBS is managed for permanent and relief staff alike.

Standards & BICSc

Methodology-based cleaning is more consistent and auditable than informal practice. BICSc or equivalent accreditation is a practical marker of professional standards.

Reporting & KPIs

A contract without structured reporting is difficult to manage. The quality of a provider's reporting reflects the quality of their management.

Staffing Resilience

Absent staff covered by overworked colleagues leads to missed areas and lower standards. How a provider covers absence is one of the most practical tests of resilience.

Who This Tool Is For

Designed for schools, trusts and those who support them

This tool is primarily intended for business managers, estates and operations leads, school leaders involved in procurement, and academy trusts preparing a single or multi-site cleaning tender. It may also be useful for consultants or advisers supporting school procurement.

Single schoolsAcademy trustsBusiness managersEstates leadsSchool leadersProcurement advisers

Start the assistant

This tool is intended as practical guidance only and should be used alongside your own procurement processes, policies and professional advice where required.

What this tool does

For: School business managers, academy trust procurement teams and local authority buyers running a school cleaning tender.

The problem it addresses: Buyers often rely on a provider's proposed questions and criteria rather than a defensible set tailored to school cleaning risk.

What you enter: Your school's postcode (we look up the school type, pupil numbers and floor area from public records) and up to three priorities.

The result it produces: Tailored tender questions, a weighted evaluation matrix with a 0–4 marking guide, KPIs with RAG thresholds, due-diligence checks, red flags and a ballpark for cleaning hours. Optionally, a branded PDF pack and a ready-to-edit Invitation to Tender in Word.

How it may support planning or review: It helps buyers run a structured, defensible procurement that probes the areas most likely to affect delivery in schools.

Developed by ICS Cleaning from over 30 years of running cleaning contracts. Free guidance to support your decisions; it does not replace a site survey.

How it works

1
Enter your school's postcode and confirm your school (trusts can add more schools).
2
Pick up to three priorities and how you want to balance price and quality, or skip and use the recommended settings.
3
Review your tender questions, evaluation matrix, KPIs and checks, and download the PDF pack.
4
If you want, build a professional tender: add your branding and dates, choose your questions and download an Invitation to Tender in Word.
5
Combine the output with professional procurement and legal advice before issue and award.

How to interpret the result

The output supports a defensible procurement but does not replace procurement or legal advice. Red flags indicate where to probe further or seek evidence; they are not a determination that a bidder is unsuitable. Evaluation criteria should be tailored to your specific contract and confirmed with your procurement lead.

Limitations

Not formal procurement advice or a substitute for your procurement team.
Not legal advice.
Not a binding quotation or contractual commitment.
Red flags are prompts to probe, not a determination of bidder suitability.

Frequently asked questions

Start with your sites (floor areas, pupil numbers, opening hours and any site plans), then decide your priorities and how you will weight price against quality. Set out clear quality questions, a marking scheme, the KPIs you will measure, the evidence bidders must supply and the legal requirements they must meet. The free School Cleaning Tender Assistant builds all of this from your school's postcode and can produce a ready-to-edit Invitation to Tender in Word.

The questions that decide whether a contract works are rarely about price. Ask about named local management and visit frequency, safeguarding and enhanced DBS checks for every person including relief staff, how absence is covered and reported, quality audits and KPIs, mobilisation and TUPE, training, and financial standing. Ask for evidence, such as a sample monthly report from a comparable school, not just assurances.

Most school cleaning tenders weight quality above price, commonly around 60% quality and 40% price. Mark each quality answer on a consistent 0 to 4 scale, convert it with (mark ÷ 4) × weighting, and treat safeguarding as pass or fail as well as scored. Price is often scored as lowest compliant price ÷ bidder's price × price weighting, with abnormally low prices checked against the hours and wage rates proposed.

A practical set covers cleaning audit scores, the school's monthly satisfaction score, contracted hours delivered, absence cover, management visits, response to issues, corrective actions closed on time, safeguarding and DBS compliance, and vacancies and staff turnover. Give each KPI a target and Red, Amber and Green thresholds, and report them monthly at school level and, for trusts, across the trust.

Key requirements include the Procurement Act 2023 (in force since 24 February 2025), the current edition of Keeping Children Safe in Education, UK GDPR and the Data Protection Act 2018, the Modern Slavery Act 2015, the Health and Safety at Work etc. Act 1974 and COSHH Regulations 2002, the Equality Act 2010 and, where staff transfer, the TUPE Regulations 2006. Check your trust's financial regulations and current procurement thresholds before you choose a route.
