UK SIC 2007 · 86101
Hospital activities (SIC code 86101)
Hospital activities is UK SIC code 86101. It sits in division 86 (Human health activities) of the SIC 2007 list. On the August 2026 Companies House register, 11,335 active UK companies list 86101 among their SIC codes. 9,937 of them list it first.
Division 86: Human health activities
Human health activities is broader than it looks. Its largest code is 86900, other human health. Physiotherapists, counsellors, psychologists, podiatrists, aesthetic clinics and a long tail of allied health practitioners all register there. It is far more mixed than the medical codes beside it. GPs incorporate under 86210. Hospital consultants and private specialists use 86220. Dental practices use 86230. Hospitals and medical nursing homes use 86101 and 86102. Many entries are personal service companies for one clinician doing private or locum work, not clinics with premises.
Who prospects SIC 86101 companies
Medical accountancy is a real specialism. Those firms watch new 86210 and 86220 incorporations, which usually mean a doctor is starting private practice. Indemnity insurers follow the same trail, along with private hospital groups offering practising privileges, medical billing services and clinic management software vendors. Dental practices attract equipment suppliers, practice sales brokers and compliance consultants. Inside 86900, split by subspecialty before you send anything. A counselling practice and an aesthetics clinic share a code and nothing else. CQC status is the other divider. It separates regulated providers from wellness businesses.

SIC 86101 is a five-digit code, and the digits are not arbitrary. The first two, 86, are the division, human health activities. Add the third and you have group 861; 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 86101 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 86101 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 86101 are London (2,085), Manchester (316), Birmingham (282), Leicester (192) and Nottingham (153). 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 86101 as a filter
11,335 companies is 0.22 per cent of the 5,190,464 active companies on the UK register, and ranks 86101 5th most used of the 6 codes we track in division 86. 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 86101
Almost everybody who uses 86101 means it: 9,937 of 11,335 companies put it first, leaving only 1,398 carrying it as a secondary code. That makes it an unusually clean filter. You can match on the code alone and trust that the companies you get really are in this line of work.
These companies are spread out. London is the largest single cluster at 18 per cent and the top five post towns together hold only 27 per cent, so the remaining 73 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 86101 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: 86101, registered office in London, incorporated in the last ninety days, which turns a 11,335 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 86101
How many UK companies use SIC code 86101?
11,335 active UK companies list 86101 (Hospital activities) among their registered SIC codes. Each company may register up to four. Of those, 9,937 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
Does a healthcare SIC code mean the company is CQC registered?
No. Directors declare SIC codes and nobody verifies them. CQC registration in England is needed only when a provider carries on regulated activities, such as surgical or diagnostic procedures. The same applies to the equivalent regulators elsewhere in the UK. Plenty of 86900 companies, including coaches, therapists and wellness practitioners, sit outside CQC scope quite legitimately. Check the regulator's register directly when compliance status matters.
Which SIC code should a locum doctor's limited company use?
Locum GPs normally use 86210. Hospital specialists use 86220. Both match the setting they work in. Allied health professionals default to 86900. Companies House runs no approval process. You select codes at incorporation and can amend them on the confirmation statement (CS01). A clinician mixing NHS locum work with a private clinic can hold several codes, up to the limit of 4.
