8 Steps to Take When Looking for a Cleaning Company
Choosing a cleaning company comes down to eight checks: define your scope, confirm relevant experience, verify insurance and compliance, check staff vetting, understand supervision and quality control, confirm absence cover, get the scope in writing, and check references — before price ever enters the conversation.
Most cleaning contracts that fail were lost at selection, not delivery. The questions you ask before signing decide the next twelve months.
This is the practical, in-order checklist for choosing a commercial cleaning company that actually performs.
The Short Answer
Work through eight steps in order: (1) define your scope, (2) check relevant experience, (3) verify insurance and compliance, (4) confirm staff vetting and training, (5) understand the supervision and quality model, (6) confirm absence cover, (7) get a written, itemised specification, and (8) check reviews and references. Price is the last filter, not the first — the cheapest quote is rarely the cheapest contract.
Key Takeaways
- Define before you compare. You can't evaluate quotes fairly without a clear, written scope of what you need cleaned and how often.
- Compliance is a filter, not a feature. Insurance, COSHH and vetting either exist in writing or they don't — rule out anyone who can't evidence them.
- Absence cover is the make-or-break clause. If it isn't documented, it will be improvised when a cleaner is off sick.
- Get the scope in writing. A spec naming every task, area and frequency is your only protection against drifting standards.
- Price is the last step. Evaluate everything else first, then compare cost on a like-for-like basis.

The Process
The 8 steps, in order
Follow them in sequence. Each step narrows the field, so by the time you reach price you're comparing genuinely capable providers on a like-for-like basis.
Define your scope and needs
Before contacting anyone, list what needs cleaning, how often, and any specialist requirements. You can't compare quotes fairly without this. If you're unsure what a full programme includes, our guide to what commercial cleaning covers is a good starting point.
Check relevant experience and specialism
Commercial cleaning is not domestic cleaning, and a school is not an office. Confirm the provider has genuine experience in your environment — an office, a school, retail, or industrial — not just general claims.
Verify insurance and compliance
Public liability and employer's liability insurance, COSHH compliance, and written risk assessments are non-negotiable. Ask for certificates and verify them — the market is unregulated at entry level and claims are often overstated.
Confirm staff vetting and training
Are operatives directly employed, vetted, reference-checked and trained — and DBS-checked where the setting requires it? Casual, unvetted labour is the root of most consistency problems.
Understand the supervision and quality model
Who supervises on site, how often, and how is quality audited? Unmanaged contracts almost always degrade within six months. Ask exactly who visits and what happens when feedback isn't acted on.
Confirm absence cover
The single most important operational clause. What happens when the regular cleaner is off sick? If there's no documented relief procedure, expect a missed clean and an unanswered email when it happens.
Get a written, itemised specification
Insist on a spec naming every area, task and frequency, plus what's included or excluded (consumables especially). A quote without a written scope invites disputes within weeks over what "clean" means.
Check reviews and references
Read Google and Trustpilot reviews, and ask for client references you can actually call. Then — and only then — compare price, ideally with a short pilot period and a no-penalty exit before any long contract.
Avoid These
Common mistakes buyers make
Choosing on price alone
The most common and most expensive mistake. A low rate usually means fewer hours, casual labour or a vague scope.
Skipping the written spec
Agreeing scope verbally guarantees a dispute the first time something is "missed."
Not asking about cover
Assuming absences are handled — until the day they aren't.
Ignoring supervision
No on-site management means standards drift with no one accountable.
Mismatching provider to site
A national giant for a small office, or a generalist for a specialist setting.
Locking in too long
Signing 12–24 months with no pilot and a punishing exit clause.
Ask Before Signing
The questions that surface the answers
These cut through marketing language and reveal how a provider actually operates. For the London-specific version of this process, see our deeper guide on how to find a good cleaning company in London.
- Who supervises the cleaning team, and how often are they on site?
- How are quality inspections carried out and reported?
- What exactly happens if a cleaner is absent — and how fast?
- Are operatives directly employed, vetted and trained?
- Are consumables included in the price or charged separately?
- Can I see proof of insurance and COSHH compliance?
- Will I have a named account manager I can reach directly?
- Can we start with a short pilot and a no-penalty exit?
On Price
What a good quote actually looks like
A quote worth trusting is itemised, scope-based and survey-led — not a single headline rate emailed without a site visit. It states the areas, frequencies and tasks, makes clear what's included and excluded, and reflects your actual premises. For how cleaning pricing is built and what's typical, see office cleaning costs in London.
Compare quotes only once you've worked through steps 1–7 — otherwise you're comparing numbers attached to completely different scopes.
How We Measure Up
How Citywide answers all eight steps
Every Citywide contract is built to pass this checklist: a written, site-specific specification; full insurance and COSHH compliance; DBS-checked, trained, directly-employed operatives; a named account manager with on-site quality audits; same-day absence cover as a contractual obligation; and an itemised quote based on a real survey. We deliver office cleaning in London and specialist services across the capital.
FAQ
Frequently asked questions
What's the most important step when choosing a cleaning company?
Confirming absence cover and getting the scope in writing. Together they prevent the two most common failure modes: a missed clean with no replacement, and a dispute over what was actually agreed. Both are easy to check before you sign and painful to fix afterwards.
Should I just choose the cheapest quote?
No. The cheapest quote is often the most expensive contract once missed cleans, weak supervision and follow-up time are counted. Treat price as the final filter after scope, compliance, vetting, supervision and cover have all been confirmed — and compare like for like.
How do I verify a cleaning company's accreditations and insurance?
Ask for certificates and verify them directly — call the certifying body or insurer rather than trusting a website badge. The cleaning market is unregulated at entry level, so accreditation claims are sometimes overstated.
Should I sign a long contract straight away?
Negotiate a short pilot period — typically four to eight weeks — with clear performance criteria and a no-penalty exit before committing to a 12-month agreement. Any provider confident in their service will accept this.
What documents should a cleaning company provide before starting?
A written, site-specific cleaning specification, proof of public liability and employer's liability insurance, COSHH data sheets and risk assessments, and evidence of staff vetting. If any can't be produced in writing, treat it as a red flag.
