Real estate is one of the busiest corners of the register, and most of it is not estate agency. The dominant code is 68209, letting and operating of own or leased property. Next comes 68100, buying and selling own real estate. Between them they hold the huge population of buy-to-let vehicles and property SPVs. Many were incorporated to hold one building. Fee-based managing agents sit under 68320. High street and online agencies use 68310. Housing association landlords use 68201.

So many entries are single-property vehicles that segmentation matters more here than almost anywhere else. Mortgage brokers, bridging lenders, insurance intermediaries, accountants and block management software firms all work the landlord codes. They watch for new incorporations, which often mean a purchase is under way. Agencies under 68310 buy different things: portals, proptech, photography and compliance services. A filing deadline hints that the company may switch accountant. Growth at a company under 68320 usually means it has won new management instructions.

SIC 68310 is a five-digit code, and the digits are not arbitrary. The first two, 68, are the division, real estate activities. Add the third and you have group 683; 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 L, real estate 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 68310 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 68310 are London (10,220), Manchester (805), Birmingham (736), Glasgow (464) and Ilford (385). 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 68310 as a filter
37,274 companies is 0.72 per cent of the 5,190,464 active companies on the UK register, and ranks 68310 4th most used of the 6 codes we track in division 68. 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.
25,306 companies put 68310 first and a further 11,968, 32 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.
These companies are spread out. London is the largest single cluster at 27 per cent and the top five post towns together hold only 34 per cent, so the remaining 66 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 68310 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: 68310, registered office in London, incorporated in the last ninety days, which turns a 37,274 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 68310
How many UK companies use SIC code 68310?
37,274 active UK companies list 68310 (Real estate agencies) among their registered SIC codes. Each company may register up to four. Of those, 25,306 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
What SIC code should a buy-to-let property company use?
Landlords letting property they own normally use 68209. Companies buying to sell rather than to rent fit 68100. You choose the codes yourself at incorporation, or change them later on a confirmation statement (CS01). No approval is needed. You can hold up to 4 codes if the company both lets and trades. Lenders often prefer to see the code that matches the loan purpose.
How do I separate landlords from letting agents in division 68?
Use the code split. Code 68310 marks estate agencies. Code 68320 marks agents managing property for a fee. Codes 68100 and 68209 mark companies dealing in or letting their own assets, so landlords and SPVs. Codes are self-selected, so some overlap exists. Pair the code with other signals, such as company name, officer count and website quality. That gives a much cleaner list.
