Cleaning company accreditations: there is no licence, so these do the work
Nobody licenses cleaning in the UK. That is why buyers lean on badges, and why the badges you show, and how you show them, decide whether you are shortlisted.
- No regulator exists
- Buyer's order, not alphabetical
- Costs and sources dated

What accreditations does a cleaning company need?
No accreditation is legally required to trade as a cleaning company in the UK, but public and larger commercial buyers routinely require one SSIP health and safety scheme (CHAS, SafeContractor, Constructionline or SMAS), ISO 9001 above roughly £100k, BICSc-trained staff, a DBS policy and COSHH records.
The absence of a regulator is the sector's credibility problem and its opportunity. A cleaning company with the right five badges, named and dated on one page, reads as a different kind of business from one that says "fully certified" and means nothing. Here they are in the order a buyer checks them, with what each costs and which buyers ask for it, from the schemes' own pages and the tender portals, read 12 September 2026.

In the order a buyer reads them
| Badge | What it is | Who asks for it | What to put on the page |
|---|---|---|---|
| SSIP scheme: CHAS, SafeContractor, Constructionline, SMAS | Health and safety pre-qualification. One is enough; the schemes recognise each other under SSIP. | Public sector, housing associations, main contractors, larger private clients | Scheme, certificate number, expiry date |
| ISO 9001 (and 14001, 45001) | Quality, environmental and H&S management systems, audited annually. | Contracts above roughly £100k; "nice to have" below (CleanTender, May 2026). Certification typically £2,000 to £8,000 | Standard, certifying body, certificate number |
| BICSc | British Institute of Cleaning Science. Corporate membership and operative certificates (CPSS). | Mandatory in some housing and NHS tenders; e.g. North Peterborough Housing estate cleaning tender, closing 14 October 2026 | Membership number, which operatives hold CPSS |
| DBS checks | Basic, standard or enhanced criminal record checks per operative. | Schools, care, healthcare, anyone holding keys; domestic customers expect it | Your policy: which level, for whom, how often renewed |
| COSHH | Control of Substances Hazardous to Health training and records. | Every commercial buyer's questionnaire | Training provider and date; colour-coding system used |
| NCCA | National Carpet Cleaners Association. | Carpet and upholstery customers and letting agents | Membership number |
| Real Living Wage | Living Wage Foundation accreditation. | Public procurement and corporate ESG teams, increasingly weighted | The badge and the year accredited |
| Insurance | Public liability, employer's liability (legally required with staff), treatment risk for carpets. | Everyone | Insurer and cover level. The one thing every buyer checks and most sites hide |
What "fully certified" means
Nothing, and buyers know it. Name the badge, the number and the date. A page that does is a tender answer; a page that does not is a reason to shortlist someone else.
What we do with it on a website
The Team and Contract packages include an accreditations page laid out in the table order above, with the certificates as downloadable PDFs where you want them, a policies section (harassment, safeguarding, TUPE, key-holding) and the insurance levels stated. It is the page a procurement manager opens second, after the home page, and the one most agencies leave as a row of logos.
Sources and method
Search volumes and cost-per-click figures are Google Ads UK data pulled through DataForSEO on the date shown.

Questions Google shows under this search
Do you need any certifications to be a cleaner?
No. There is no licence, no register and no compulsory qualification for cleaning in the UK, which is why anyone can start trading tomorrow. What changes that is who you clean for: schools and care settings require DBS checks, public tenders require an SSIP scheme, and larger contracts require ISO 9001. For a domestic cleaner, insurance and a DBS check are what customers actually look for.
What is ISO in cleaning?
ISO standards are management systems, not cleaning methods. ISO 9001 covers quality, 14001 environmental management and 45001 health and safety. A cleaning company certified to ISO 9001 has documented processes an auditor has checked annually. Certification typically costs £2,000 to £8,000 and becomes worth it when you bid for contracts above roughly £100,000.
What are the top 10 ISO certification bodies in the UK?
Look for a body accredited by UKAS, the UK Accreditation Service, rather than a list of names. A UKAS-accredited certificate is the one a procurement team will accept; a certificate from an unaccredited body often is not. Check the certifying body on the UKAS register before you pay anyone.
What are company accreditations?
Independent verification that a business meets a published standard, issued by a body that audits you rather than takes your word for it. In cleaning they stand in for the licence the trade does not have. The ones that matter are listed in the table above, in the order a buyer checks them.
