Generate Professional ProposalsWhat Are Cleaning Tenders and How Do They Work?
A tender is a formal invitation for cleaning companies to bid for a service contract. They're issued by public sector bodies (NHS, government, local councils) and large corporates when they need to procurement services competitively. In the UK, any public sector contract over £25,000 must be tendered publicly. This creates 1,000s of cleaning opportunities annually across the NHS, central government, and local authorities.
Why Are Tenders Valuable?
Large Contract Values
£50,000-£500,000+ annually. Signed for 3-5 years with renewal options. Predictable revenue.
Level Playing Field
Tenders evaluate all bidders equally. You compete on quality and systems, not relationships.
Recurring Revenue
Contracts renew annually or at fixed intervals. No chasing new clients every year.
Public Sector Stability
Government and NHS pay reliably on time. No insolvency risk like with small businesses.
The Tender Process: 5 Stages
1. Tender Published
Posted on Contracts Finder, NHS Supply Chain, or client website. Includes overview, requirements, submission deadline (usually 4-6 weeks away).
2. PQQ Submission
Pre-Qualification Questionnaire. You answer: company history, insurance, accreditations, financials, health & safety record, staff vetting processes. Typically 20-40 questions in an Excel/online form. Deadline 4-6 weeks out.
3. PQQ Evaluation
Client reviews submissions and shortlists to 3-5 suppliers. Takes 4-8 weeks. You get notified if you've passed or failed.
4. ITT Submission (for Shortlisted)
Invitation to Tender—the detailed proposal. Typically 50-100 pages: method statements, staff bios, pricing breakdown, quality assurance plans, timelines, references from similar contracts.
5. Evaluation & Award
Client scores ITTs and awards to winner. Often includes interviews or site visits. Notification of award and contract start date (typically 4-8 weeks after ITT deadline).

Passing the PQQ: Pre-Qualification Questionnaire Strategy
The PQQ screens out unqualified bidders before resources are wasted on full proposals. If you fail the PQQ, you never proceed. Success here requires thorough preparation, accurate information, and strategic positioning.
10 Key PQQ Questions and How to Answer Them
Q: How many years has your company been trading?
A: Minimum 3 years. If you're newer, emphasise key staff experience. Example: "We were established 2022, but our management team has 50+ combined years in commercial cleaning." Many councils require 3+ years; some allow 2 for specialist roles.
Q: Are you currently insolvent or do you have director disqualifications?
A: Answer "No". They'll check Companies House. If yes, disclose upfront and explain. Most will shortlist compliant companies only.
Q: What is your annual revenue and profit?
A: Be honest. Turnover £250k+ and positive profit shows stability. If smaller, frame positively: "£180k turnover with 15% net margin demonstrates healthy operations." They're checking ability to manage large contracts, not just size.
Q: Do you have public liability insurance?
A: Yes, and state the cover amount: £1M-£5M for most NHS/corporate contracts. Provide certificate. No cover = automatic fail for public sector.
Q: Do you have employer's liability insurance?
A: Yes, £10M+ for contracts with staff on client site. This is non-negotiable for UK employment law. Provide documentation.
Q: What accreditations do you hold?
A: List all: ISO 9001 (Quality Management, highly valued), SafeContractor (health & safety), CHAS (risk assessment), Achilles UVDB (compliance vetting). Each adds major credibility. If none, prioritise ISO 9001 immediately.
Q: Describe your health and safety management system
A: Outline your processes: risk assessments, staff training records, incident reporting, PPE provision, COSHH compliance. Provide a summary and offer to submit full policy. Shows systematic approach.
Q: Do you have DBS checks for all staff? What is your vetting process?
A: Mandatory for NHS/government. Answer: "Yes. All staff on client sites have valid DBS checks (Standard or Enhanced). Records stored securely, updated every 3 years. All staff sign confidentiality agreements." Provide process documentation.
Q: Can you provide references from similar contracts?
A: Ideal: 3 references from current or recent (within 2 years) contracts of similar size/scope. NHS trusts prefer NHS clients. If new to government sector, provide references from any large commercial facilities. Get written permission from referees before submitting.
Q: What is your capacity to deliver this contract? How many staff?
A: Show you can scale. Example: "We currently manage 12 contracts with 45 permanent staff and access to 20 flexible staff. This contract requires 8-10 dedicated staff—well within capacity. We have dedicated operations manager and QA officer." Overconfidence fails; realistic shows professionalism.
PQQ Pro Tips
- • Proofread everything. Typos suggest carelessness.
- • Be consistent. If you say 45 staff in Q1, don't say 40 in Q5.
- • Provide evidence. Reference companies will be contacted; make sure referees expect calls.
- • Match their scoring criteria. If they weight health & safety 40%, emphasise your systems.
- • Submit early. Last-minute submissions get less attention and risk technical failures.
Winning the ITT: Invitation to Tender Response
The ITT is where you prove your capability. It's typically 50-100+ pages covering method statements, timelines, pricing, staffing, quality assurance, references, and compliance documentation. Winning ITTs follow a formula: clear structure, detailed method statements, realistic pricing, and risk mitigation.
7-Section ITT Structure That Wins
Executive Summary (2-3 pages)
Summarise your understanding of the contract: scope, timeline, pricing, and unique value. Example: "For the 15,000 sqm NHS trust estate, we propose: Daily deep cleaning of patient-facing areas, weekly enhanced cleaning, real-time quality tracking with monthly audit reports, 24-hour emergency response, and dedicated compliance liaison. Cost: £180,000 annually. Start: January 2026."
Your Understanding of the Facility & Requirements (5-8 pages)
Prove you understand their specific needs. Break down building areas, cleaning requirements per space (patient areas need highest hygiene), staffing model, compliance gaps in current provider, and your remediation plan. This shows you've done your homework.
Method Statements & Cleaning Scope (15-25 pages)
Detailed "how you'll clean" for each area. For NHS: Daily cleaning protocols for wards (detergent + disinfectant per specification), terminal cleans post-discharge, high-touch point frequency (4x daily for door handles, light switches), waste segregation processes, infection control compliance. Include timings, equipment, staff roles, and quality checkpoints.
Staffing & Management Structure (5-10 pages)
Org chart showing: contract manager (1), supervisor (1), lead cleaner (2-3), cleaners (8-12 depending on scope). Include staff bios highlighting relevant experience. For NHS: state DBS checks, health & safety certifications, product knowledge training. Include staff retention strategy (salary, benefits, training investment).
Quality Assurance & Compliance (8-12 pages)
Your quality system: Daily checklist audits by supervisor, weekly manager audits, monthly client-led audits, quarterly independent audits. Compliance: daily infection control checks (for healthcare), waste segregation verification, environmental monitoring. Documentation: Monthly KPI reports (cleanliness score, staff attendance, incident log). Technology: Client mobile app access to quality data in real-time.
Health & Safety, Risk Management & Insurance (5-8 pages)
Risk assessment document (RAMS—Risk Assessment & Method Statement): per-area safety protocols, PPE requirements, cleaning chemical hazards (COSHH), sharps handling (for healthcare), lone worker safeguards, incident reporting process. Insurance certificates (public liability £5M, employer's liability £10M+). Compliance certifications (ISO 9001, SafeContractor, CHAS, Achilles UVDB if applicable).
Pricing Breakdown & Contract Terms (3-5 pages)
Line-by-line cost: labour hours × rate, materials cost, overheads allocation, compliance system cost, profit margin. Example: "Daily labour (12 cleaners × 8 hrs × £13/hr) = £108,000/yr. Materials £18,000/yr. Compliance systems £8,000/yr. Contingency 5% = £8,100. Total £142,100." Include contract start date, service hours, payment terms (Net 30), performance KPIs, and penalty/incentive clauses.
ITT page count varies: 50-80 pages typical for mid-market contracts (£50k-£200k), 100+ pages for large contracts (£200k+). Quality trumps length—a clear, detailed 60-page ITT beats a rushed 120-page document.
Compliance Requirements: Don't Miss These
UK tender requirements are strict. Missing even one compliance requirement often results in automatic rejection. Build your compliance "passport" before bidding.
Compliance Checklist for All Tenders
Public Liability Insurance
£1-5M cover required. Current certificate needed at bid and at contract start.
Employer's Liability Insurance
£10M+ for staff on client site. Mandatory for UK employment law.
ISO 9001 Quality Management
Increasingly required for NHS and corporate tenders. Obtain certification or defer bidding.
Health & Safety Policy
Written policy covering risk assessment, incident reporting, PPE provision. Provide to bid.
COSHH Assessment & Training
For tenders involving cleaning chemicals or healthcare. Document training for all staff.
DBS Checks for Staff
All staff on NHS/govt site must have DBS Standard or Enhanced. Records kept for 3 years minimum.
SafeContractor/CHAS Registration
Increasingly required. Demonstrates health & safety compliance. Plan 4-6 weeks for accreditation.
Achilles UVDB (Large Contracts)
For FTSE companies and large tenders. Vendor vetting system. Registration takes 2-3 weeks.
Environmental Policy
For some public sector tenders. Outline waste recycling rates, sustainable sourcing practices.
Modern Slavery & Ethics Policy

Action Item
Create a digital folder with all compliance documentation (insurance PDFs, policies, DBS summary records, certifications). Update quarterly. Before each tender bid, verify nothing has expired. Missing compliance = automatic rejection.
Tender Pricing: The Formula That Wins
Tender prices are more transparent than direct sales. Clients publish them openly and often compare multiple bids. Your pricing must be competitive but sustainable. Underbid = lose money. Overbid = lose contract.
Tender Pricing Formula
Annual Price = (Labour + Materials + Overheads) × 1.15 + Compliance Systems + Profit Margin
Labour: Staff hours (daily schedule) × hourly rate (£12-15/hr base + holiday/pension)
Materials: Cleaning products, waste disposal, PPE (~15% of labour cost for standard cleaning)
Overheads: Transport, insurance, office admin, manager salary (typically 20-25% of labour)
Compliance Systems: Quality audits, mobile app licensing, training (£5k-£15k annually for large contracts)
Profit Margin: 20-35% depending on contract size and risk. Larger contracts accept lower %; smaller contracts require higher %.
Example: NHS Trust Tender (15,000 sqm estate, £200k budget)
Daily cleaning: 12 staff × 8 hours × £13/hour = £1,248/day
Annual labour (260 working days): £1,248 × 260 = £324,480
Materials & consumables (15% of labour): £48,672
Overheads (20% of labour): £64,896
Compliance systems (audits, app, training): £12,000
Subtotal: £450,048
Profit margin (25% for large contract): £112,512
Your Bid: £562,560 annually (~£46,880/month)
If the budget is £200k and you're at £562k, revisit: Can you reduce staffing? Propose less frequent deep cleaning? Negotiate fixed staffing with client performance clauses? Sometimes tenders are genuinely under-budgeted—either reduce scope or decline to bid.
Pro Tip: When bidding multiple tenders, track your win rate by price point. If 60% of tenders under £150k go to lowest bidder, consider that segment differently than £150k+ tenders (where quality + price matters more).
Common Tender Mistakes That Cost You Contracts
Submitting Late or Incomplete PQQs
Problem: Missing just one required field can result in automatic rejection. Online forms don't always show all questions clearly.
Fix: Submit 48 hours early. Print the form, fill out on paper, then transfer to online. Review twice before hitting submit.
Providing Outdated Insurance Certificates
Problem: You submit an insurance certificate that expires before contract start date. Automatic fail.
Fix: Check insurance expiry dates when bidding. Renew 30 days before expiry. Always attach current, valid certificates.
Generic Method Statements
Problem: Your ITT method statement reads like every other company's—clients spot this and lose confidence.
Fix: Customise every method statement with facility-specific details: "Your 2,000 sqm office has 15 toilet stalls, 40 desk positions, and high-touch entry areas requiring 4x daily disinfection."
Pricing Below Sustainable Cost
Problem: You win the £80k contract bid at £78k but your costs are £85k. You lose money for 3 years.
Fix: Calculate true labour + overhead cost. Add 20-30% margin minimum. If you can't hit that, don't bid or reduce scope.
Missing Compliance Requirements
Problem: Your PQQ lists ISO 9001 but you don't actually have it. Client checks and rejects you.
Fix: Never claim certifications you don't have. If ISO 9001 is required and you lack it, get certified (4-6 weeks) or don't bid.
No Risk Management Plan
Problem: Your ITT doesn't address what happens if a key staff member quits or cleaning product shortage occurs.
Fix: Include contingency plan: backup staff training, alternative product suppliers, escalation procedures. Shows professionalism.

Frequently Asked Questions
What is the difference between a PQQ and an ITT in cleaning tenders?
A PQQ (Pre-Qualification Questionnaire) screens out unqualified bidders early. It covers company background, financial stability, insurance, accreditations, and health & safety history. If you fail the PQQ, you don't proceed. An ITT (Invitation to Tender) is the detailed technical and financial proposal from shortlisted companies. It covers methodology, staffing, pricing, and detailed scope. Winning tenders requires excellence in both.
How often are UK public sector cleaning tenders released?
Public sector tenders (government offices, NHS trusts, local councils) are released on a rolling basis year-round. Most major tenders are released January-March and July-September. NHS Supply Chain updates tenders quarterly. Contract values typically £50,000-£500,000+ annually. Subscribe to Contracts Finder and set up email alerts to never miss a tender in your area.
What compliance certifications do I need to win tenders?
Minimum requirements: ISO 9001 (quality), public liability insurance £1-5M, employer's liability £10M+. For government/NHS contracts: DBS checks for all staff, SafeContractor or Achilles UVDB registration, HSE compliance, method statements (RAMS). For sensitive sectors: COSHH training, waste disposal certifications, health & safety policy documentation. Higher tier tenders require environmental certifications (ISO 14001).
How long does a tender process typically take?
Standard timeline: Tender released → 4-6 weeks for submissions → Evaluation (4-8 weeks) → Shortlist announced → Final interviews/negotiations (2-4 weeks) → Contract signed → Start date (typically 8-12 weeks total). Some accelerated tenders compress this to 6-8 weeks. Plan to allocate 40-60 hours per tender response.
How do I price a tender to win without losing money?
Tender pricing formula: (Labour cost per hour × annual hours) + (Overheads × 1.3) + (Margin 20-35%). For £50,000/year contract: Labour £35,000 + Overheads £8,000 + Compliance systems £3,000 + Profit £4,000 = £50,000. Don't race to bottom; tender evaluators weight quality and compliance 40-50%, price only 30-40%. Price confidently at sustainable levels.
Where do I find UK cleaning tenders?
Main tender sources: 1) Contracts Finder (UK government contracts), 2) NHS Supply Chain (NHS estate), 3) ProContract (corporate framework), 4) Bravo Solution (large corporates), 5) Tender portals (local council websites), 6) Trade Press (Cleaning Matters, BSG World).
