UK SIC 2007 · 39000
Remediation activities and other waste management services (SIC code 39000)
Remediation activities and other waste management services is UK SIC code 39000. It sits in division 39 (Remediation activities and other waste management services) of the SIC 2007 list. On the August 2026 Companies House register, 3,707 active UK companies list 39000 among their SIC codes. 2,782 of them list it first.
Division 39 is the smallest waste division. It has one UK code, 39000, for remediation and other waste management services. Companies here clean up contaminated land and buildings. The work includes brownfield soil remediation, asbestos removal, decontamination, invasive weed treatment such as Japanese knotweed, and spill response. The public record mixes real remediation contractors with environmental services firms who picked this code because nothing else fit. Most of the work is project-based. It follows construction, demolition and property deals.

Who prospects SIC 39000 companies
Remediation feeds straight into development, so the construction supply chain does most of the selling. Groundworks contractors look for specialist partners. Demolition firms and developers commission site investigations. Plant hire companies supply excavators and screening kit. Environmental insurance and surety providers target the unusual liability profile. New incorporations often follow a regulatory push, such as tighter asbestos or contaminated land enforcement. A young firm here needs accreditations, insurance and tender support before it can win work. Growth at an older firm usually means the local development market is strong.

SIC 39000 is a five-digit code, and the digits are not arbitrary. The first two, 39, are the division, remediation activities and other waste management services. Add the third and you have group 390; 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 E, water supply, sewerage and waste management, 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 39000 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 39000 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 39000 are London (421), Manchester (74), Glasgow (68), Birmingham (55) and Nottingham (47). 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 39000 as a filter
3,707 companies is 0.07 per cent of the 5,190,464 active companies on the UK register, and ranks 39000 most used of the 1 codes we track in division 39. 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 39000
2,782 companies put 39000 first and a further 925, 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.
These companies are spread out. London is the largest single cluster at 11 per cent and the top five post towns together hold only 18 per cent, so the remaining 82 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 39000 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: 39000, registered office in London, incorporated in the last ninety days, which turns a 3,707 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 39000
How many UK companies use SIC code 39000?
3,707 active UK companies list 39000 (Remediation activities and other waste management services) among their registered SIC codes. Each company may register up to four. Of those, 2,782 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
Which SIC code should an asbestos removal company use?
39000 is the usual choice, because asbestos removal is a decontamination activity. Some firms register a specialised construction code from division 43 instead, since the work happens on building sites. Both readings are defensible. The licence that really matters comes from the Health and Safety Executive, and it has nothing to do with your SIC code. Listing 39000 next to a construction code covers both views of the business.
Can a groundworks contractor add 39000 to reflect remediation work?
Yes, and many do. A company can hold up to four SIC codes from any divisions. Pairing a division 43 groundworks code with 39000 describes a contractor who handles contaminated soil during enabling works. Add the code on your next confirmation statement. There is no approval process, and the change appears on the public record once the statement is filed.
