UK SIC 2007 · 66300
Fund management activities (SIC code 66300)
Fund managers file here. The code holds asset managers, hedge funds, private equity, venture capital, pension fund managers and unit-trust managers. Almost all of them sit in London or Edinburgh.
This division gathers the middlemen of financial services. Insurance agents and brokers sit under 66220. Fund managers use 66300. Security and commodity dealing firms use 66120. A wide population of advisers and support businesses sits under 66190, which covers auxiliary financial intermediation not classified elsewhere. Many independent financial advisers and mortgage intermediaries pick 66190 or 66290. So the auxiliary codes are a mix. You get one-adviser practices, appointed representatives and back-office service firms, not one recognisable trade.
Who prospects SIC 66300 companies
Plenty of suppliers work this water. They sell compliance support, professional indemnity cover, CRM and back-office platforms, paraplanning services and recruitment. Acquirers consolidating adviser books hunt here too. Three signals help. A brand new company often means an adviser has gone independent. A looming confirmation statement or accounts deadline hints at thin admin support. And the poor-website filter finds firms still trading on referrals, which makes them a strong fit for marketing services.
Lead generation for insurance & financial brokers →How to read SIC 66300
SIC 66300 is a five-digit code, and the digits are not arbitrary. The first two, 66, are the division, activities auxiliary to financial services and insurance activities. Add the third and you have group 663; 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 K, financial and insurance activities, the broadest tier there is. Reading a code left to right therefore goes from a whole sector down to one activity.
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 66300 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 66300 are London (2,918), Edinburgh (153), Birmingham (50), Manchester (48) and Glasgow (40). 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 66300 as a filter
5,456 companies is 0.11 per cent of the 5,190,464 active companies on the UK register, and ranks 66300 third most used of the 7 codes we track in division 66. 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.
4,083 companies put 66300 first and a further 1,373, 25 per cent, list it in one of their other three SIC slots. That gap is the difference between a tight list and a broad one. First-code-only is the safer filter when you are writing to them; matching any position is worth it when you need the volume.
The population is concentrated: the five busiest post towns hold 59 per cent of it, and London alone accounts for 53 per cent. If you sell nationally, those five towns are most of the market. If you sell locally and you are not in one of them, expect a much smaller pool and widen the radius early.
In practice the code on its own is rarely the whole filter. Pair 66300 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: 66300, registered office in London, incorporated in the last ninety days, which turns a 5,456 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.
