Who prospects SIC 88990 companies
Home care agencies under 88100 buy heavily. They need care worker recruitment, rostering and medication management software, franchise systems and help with regulatory registration. A new incorporation often means a franchisee starting up, or an experienced care manager going out alone. Nurseries and day-care settings buy premises fit-outs, parent communication apps and payroll built for shift staff. Councils and funders shape much of the revenue, so tender alert services sell well here. Separate commercial from voluntary entities early. Grant-funded organisations buy on completely different cycles.

SIC 88990 is a five-digit code, and the digits are not arbitrary. The first two, 88, are the division, social work activities without accommodation. Add the third and you have group 889; the fourth narrows it to a class, and the fifth to the subclass, which is the level Companies House actually asks a company to pick. The whole division sits under section Q, human health and social work, the broadest tier there is. Reading a code left to right therefore goes from a whole sector down to one activity.
More on how SIC 88990 is built
A company chooses its own codes when it incorporates and can change them on any confirmation statement. It may list up to four, and Companies House does not check whether they are right. That is why 88990 is worth reading as a claim the company made about itself rather than as a verified fact, and why the first-position and any-position counts above differ.
Measured on the August 2026 register, the busiest registered-office post towns for 88990 are London (5,473), Birmingham (724), Manchester (514), Liverpool (289) and Nottingham (284). Those are registered-office locations, which is where the paperwork sits rather than necessarily where the work happens, so treat them as where to start looking rather than as a service area.
Using SIC 88990 as a filter
24,121 companies is 0.46 per cent of the 5,190,464 active companies on the UK register, and ranks 88990 most used of the 3 codes we track in division 88. That is the pool before any filter. Whether it is a big market for you depends on what you sell, but it is the number every other filter on this page cuts down from.
More on filtering by SIC 88990
Only 13,146 of the 24,121 companies carrying 88990 put it first. The other 10,975, 45 per cent, list it behind another code, which usually means the business does more than one thing and files 88990 as a sideline. A search that matches the first code only will miss most of this population, so match on any of the four SIC positions and use a second filter to tighten it.
These companies are spread out. London is the largest single cluster at 23 per cent and the top five post towns together hold only 30 per cent, so the remaining 70 per cent sits across the rest of the country. A regional filter narrows this list without gutting it, which makes it a reasonable code to work territory by territory.
In practice the code on its own is rarely the whole filter. Pair 88990 with an incorporation date to catch companies in their first months, when they are still choosing suppliers, or with a filing deadline to reach them while the year end is on their mind. A worked example for this code: 88990, registered office in London, incorporated in the last ninety days, which turns a 24,121 company pool into a list you can write to in an afternoon. Add the poor-website filter if what you sell is a website, or a recent change of officer if you sell to whoever just took the job. Every company you pull carries the Companies House record, the director's name, a verified website and a verified email, and the ones we cannot complete are not charged.

About SIC 88990
How many UK companies use SIC code 88990?
24,121 active UK companies list 88990 (Other social work activities without accommodation n.e.c.) among their registered SIC codes. Each company may register up to four. Of those, 13,146 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
Should a home care agency use 88100 or a division 87 code?
If care is delivered in clients' own homes, 88100 is correct. Division 87 codes describe residential settings, where people live on the provider's premises. The split matters when you build a list. The two models face different regulatory requirements, carry different costs and buy different things. Codes are self-declared and changeable on any confirmation statement (CS01), with up to 4 allowed per company.
Which SIC code fits a private nursery, 88910 or 85100?
Both turn up in practice. Code 85100 leans towards pre-primary education. Code 88910 leans towards day care. Many settings genuinely do both. Companies House does not adjudicate, so directors pick whichever fits, or list both within the allowance of up to 4. Whatever code you choose, providing regulated childcare still needs registration with Ofsted or the equivalent national regulator.
