Contract Cleaning in Ireland: How It Works, What It Costs & How to Choose (2026)

What Is Contract Cleaning?

Contract cleaning is an ongoing agreement between a business and a professional cleaning company to provide regular, scheduled cleaning services. Unlike ad-hoc cleaning (calling someone when you need a clean), contract cleaning provides a guaranteed service level with consistent standards, dedicated staff, supervision, and quality measurement.

The contract defines exactly what will be cleaned, how often, to what standard, and at what cost. It creates accountability on both sides: the cleaning company commits to delivering the specified service, and the client commits to paying the agreed fee for the agreed term.

The vast majority of commercial premises in Ireland use contract cleaning: offices, hotels, hospitals, schools, universities, retail units, factories, warehouses, airports, and public buildings. For most businesses, it is more cost-effective and lower-risk than employing cleaners directly.

How Contract Cleaning Works

The typical contract cleaning process in Ireland follows these steps:

1. Site Survey

The cleaning company visits your premises to assess the size, layout, surface types, usage patterns, and any specialist requirements. This is not optional — any company quoting without a site visit is guessing. At Optus Glean, we conduct a detailed walk-through, take measurements, and discuss your specific needs and pain points with your facilities team.

2. Cleaning Specification

Based on the site survey, the cleaning company produces a detailed cleaning specification: a document listing every area, every task, and the frequency of each task. This is the most important document in the entire contract. A good specification eliminates ambiguity and sets clear expectations. For guidance on what a specification should include, see our office cleaning checklist.

3. Quotation

The cleaning company provides a fixed-price quotation based on the specification. This should be a monthly fee (not just an hourly rate) so you know exactly what you will pay. The quote should itemise what is included: labour, supervision, chemicals, consumables, equipment, and any periodic deep cleaning tasks.

4. Contract Agreement

Once terms are agreed, a formal contract is signed covering: the specification, the price, the contract term, the notice period, insurance requirements, GDPR compliance, health and safety responsibilities, and the quality audit process.

5. Mobilisation

The cleaning company deploys staff to your site. This typically involves: staff selection and induction, key/alarm code exchange, equipment and chemical delivery, initial deep clean (if the premises has been under-cleaned), and establishing the daily routine.

6. Ongoing Service

Regular cleaning is delivered according to the specification. A dedicated supervisor conducts periodic site visits and quality audits. Any issues are communicated through an agreed channel (usually a dedicated contact person on each side).

Pricing Models for Contract Cleaning

Contract cleaning in Ireland is priced using several models. Understanding these helps you compare quotes effectively.

For most businesses, the fixed monthly fee is the best model because it provides cost certainty and aligns the cleaning company's interest with yours — they are incentivised to clean efficiently rather than to maximise hours. For a detailed breakdown of all cleaning costs, see our cleaning prices guide.

What to Look for in a Contract Cleaning Provider

Choosing the right cleaning company is one of the most important facilities management decisions you will make. Here are the ten criteria that matter most:

1. Insurance

This is non-negotiable. The cleaning company must carry adequate public liability insurance (€6.5M minimum is the industry standard) and employer's liability insurance (€13M minimum). Ask for a copy of the insurance certificate and check it is current. If a cleaner damages your property or injures themselves on your premises, insurance is the only thing that protects you.

2. Garda Vetting

All cleaning staff working on your premises should be Garda vetted. This is especially important for offices (access to confidential documents and IT equipment), healthcare settings (patient safety), and any premises with vulnerable people. Ask how the company manages vetting and what their policy is for staff who have not yet been vetted.

3. Written Specification

If the cleaning company does not provide a detailed written specification, walk away. A verbal agreement or a one-paragraph scope of work is not sufficient. The specification should list every room, every task, and every frequency. It is the foundation of accountability.

4. Quality Audits

How does the company measure and maintain quality? The best providers conduct regular scored audits (monthly or quarterly) with photographic evidence and share the results with you. This creates a documented quality record that drives continuous improvement.

5. Supervision

Who supervises the cleaners on your site? Large companies have area managers who visit each site regularly. Smaller companies may rely on the business owner to supervise. Either can work, but there should be a named individual responsible for quality at your premises.

6. Backup Staff

What happens when your regular cleaner is sick, on holiday, or leaves the company? A professional cleaning company has relief staff trained and ready to cover. A one-person operation leaves you without a cleaner. Ask about the backup plan and how quickly relief staff can be deployed.

7. Transparent Pricing

The quote should be clear about what is included and what is not. Are chemicals included? Are consumables (toilet rolls, hand soap, paper towels) included? Is equipment provided? Are periodic deep cleans included or extra? Hidden costs are a common source of friction in cleaning contracts.

8. Contract Terms

Review the contract carefully. What is the term (12 months is standard)? What is the notice period (30–90 days is normal)? Is there an automatic renewal clause? What are the grounds for early termination? What is the annual price review mechanism?

9. Financial Stability

Check the company's financial health. In Ireland, you can search the CRO (Companies Registration Office) for filed accounts. A cleaning company that is financially distressed may cut corners on staff pay, chemicals, and equipment — all of which affect your cleaning quality.

10. References

Ask for references from current clients, ideally in your sector. A cleaning company that cleans offices well may not be the right fit for a hospital, and vice versa. Speak to the references and ask about reliability, quality, responsiveness, and how the company handles problems.

Red Flags When Choosing a Cleaning Company

These warning signs should make you cautious:

• Price significantly below market rate: If a quote is 30%+ below the others, the company is likely underpaying staff, skipping insurance, or planning to cut the scope after you sign.
• No site survey: A company quoting without visiting your premises is guessing. The quote will be inaccurate and the service will not match your expectations.
• No written specification: "We'll clean the whole office" is not a specification. Without a detailed task list, there is no basis for measuring performance.
• Cannot provide insurance certificate: No insurance = no protection. Do not accept "it's being renewed" or "I'll send it later."
• No Garda vetting: Staff working in your premises out of hours with access to your equipment, documents, and data must be vetted.
• No contract or very long lock-in: Reputable companies are confident in their service and offer reasonable contract terms. A 36-month lock-in with no break clause suggests the company knows you will want to leave.
• High staff turnover: If the company cannot retain staff, your premises will have a rotating cast of unfamiliar cleaners, which means inconsistent quality and higher security risk.

TUPE: What Happens When You Switch Providers

TUPE (Transfer of Undertakings — Protection of Employment) is one of the most misunderstood aspects of contract cleaning. Here is what you need to know:

What Is TUPE?

TUPE is an EU directive (implemented in Ireland under SI 131/2003) that protects employees when a business, or part of a business, transfers from one employer to another. In contract cleaning, TUPE typically applies when you switch from one cleaning provider to another, because the "undertaking" (the cleaning of your premises) is transferring.

What Does TUPE Mean in Practice?

• The cleaners currently working on your site have the right to transfer to the new cleaning provider on their existing terms and conditions (pay rate, hours, seniority, holiday entitlement).
• The new provider must accept the transferring employees and cannot reduce their terms.
• Both the outgoing and incoming providers must consult with affected employees about the transfer.
• Dismissal of an employee solely because of the transfer is automatically unfair.

TUPE Implications for You as the Client

TUPE is primarily a matter between the outgoing and incoming cleaning companies, but it affects you because:

• The incoming provider's quote must account for the cost of the transferring staff (their existing pay rates may be higher or lower than the new provider's standard rates).
• If your current cleaners are experienced and know your premises well, TUPE is actually beneficial — you keep the same people but with a better company managing them.
• The transition period requires coordination between you, the outgoing provider, and the incoming provider. Allow 4–8 weeks.

How to Switch Cleaning Companies

If you are unhappy with your current cleaning provider, here is a step-by-step switching guide:

1. Review your contract: Check the notice period, termination terms, and any automatic renewal clauses. Most contracts require 30–90 days' written notice.
2. Document the issues: Keep a written record of quality failures, missed cleans, complaints, and any formal correspondence. This is essential if you need to justify early termination.
3. Prepare a specification: Use this guide and our office cleaning checklist to write a detailed specification for the new contract.
4. Invite quotes: Contact 3–5 cleaning companies. Insist on a site survey before quoting. Provide the specification and ask for a fixed monthly price.
5. Evaluate quotes: Compare on quality indicators (insurance, vetting, specification detail, audit process, references), not just price. The cheapest is rarely the best.
6. Serve notice: Give formal written notice to your current provider in accordance with the contract terms.
7. Manage TUPE: The outgoing and incoming providers should manage the TUPE consultation. You may need to facilitate introductions and share relevant employee information (with GDPR compliance).
8. Mobilise: The new provider conducts staff induction, receives keys and alarm codes, delivers equipment, and begins service. Expect the first 2–4 weeks to be a settling-in period.
