What people sell to specialist cleaning companies
If you are one of these, this market is a list rather than a guess. Every company below is on the public record with its registered office, incorporation date, officers and filing history.

- Cleaning equipment sales, hire and servicing
- Employers' liability and contract cleaning insurance
- Workforce scheduling and mobile time-and-attendance
- DBS checking and right-to-work screening
- Uniform, PPE and branded workwear
What SIC 81222 actually tells you
Nearly half the companies carrying this code file it as a secondary, usually facilities firms and property services businesses that clean among other things. If you sell to cleaners specifically, first position is the honest filter. If you sell to anyone who cleans, match any position and you roughly double the pool.
In numbers: 7,385 companies put 81222 first and 5,624 carry it in one of their other three SIC slots, so 57 per cent of the population leads with it. Together they are 0.3 per cent of the 5,190,464 active companies on the UK register.
Specialised cleaning services by post town
Measured on the August 2026 register, these are the registered-office post towns with the most specialist cleaning companies. London holds 17 per cent of the national population on its own. A registered office is where the paperwork sits rather than where the work happens, so treat this as where to start looking, not as a service area.

Timing
Contract cleaning is a churn business and new entrants are constant. The first purchase after formation is almost always insurance and consumables, and the supplier chosen then tends to keep the account for years.
A worked filter for this market: SIC 81222, registered office in London, incorporated in the last ninety days. That turns 13,009 companies into a list you can write to in an afternoon. Add the poor-website filter if what you sell is a web presence, or a recent change of officer if you sell to whoever just took the job.
The rest of division 81
A trade rarely sits in exactly one code. Specialised cleaning services is in division 81, services to buildings and landscape activities, and the codes below are its nearest neighbours on the public record: another 88,159 companies describing themselves in adjacent terms. If your product suits the wider trade rather than this one code, pull two or three of them together.
You only pay for leads that arrive complete.
You carry the bounce rate and the compliance risk for data somebody else assembled and will not explain
Leads that arrive verified with the filing behind each field, so the ICO question has a written answer
Every specialist cleaning companie you pull arrives with its Companies House record, the director’s name, a verified website and a verified email. The ones we cannot complete are not charged for.
What if a company has no website?
Trades with a lot of very small companies tend to have patchy web presence, and a list that charges you per row will happily sell you the rows it could not finish. Here you are charged for a complete lead or not at all, which means the size of the market above is the ceiling, not the invoice.
Is emailing these companies legal?
This is public-record data about businesses, and reaching a company at a published business address is normal B2B contact. The lawful basis is legitimate interest, every message carries an opt-out, and anyone who asks to be removed is suppressed across the whole system rather than on one list. If a company asks us directly, we take its record out within twenty-four hours. None of that is optional or an upgrade.
