Manufacture of electric domestic appliances (SIC code 27510)
Manufacture of electric domestic appliances is UK SIC code 27510. It sits in division 27 (Manufacture of electrical equipment) of the SIC 2007 list. On the August 2026 Companies House register, 526 active UK companies list 27510 among their SIC codes. 396 of them list it first.
Division 27: Manufacture of electrical equipment
Companies in division 27 make electrical hardware. That means lighting, wiring devices, batteries, cables, motors, switchgear and household appliances. The most used code on the UK register is 27900, manufacture of other electrical equipment. It is the leftover category. It holds control panel builders, LED lighting specialists, and makers of chargers, transformers and niche electronic assemblies. Panel builders are especially common here. Assembling switchgear and control systems for industry does not fit anywhere else nearly as well.

Who prospects SIC 27510 companies
Accountants come here for research and development tax relief work. Product development is normal in this trade, and many smaller firms still underclaim. Component distributors, contract electronics manufacturers and compliance houses handling UKCA and CE marking follow behind. So do technical recruiters. Growth signals show which firms are scaling production. When they scale, they buy testing, certification and quality systems all at once. A new incorporation may be a hardware start-up. It may also be an experienced engineer turning a design into a product. Either way, early talk about funding and prototyping lands well.

SIC 27510 is a five-digit code, and the digits are not arbitrary. The first two, 27, are the division, manufacture of electrical equipment. Add the third and you have group 275; 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 C, manufacturing, 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 27510 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 27510 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 27510 are Beckenham (83), London (79), Cambridge (16), West Midlands, England (14) and Kington (13). 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 27510 as a filter
526 companies is 0.01 per cent of the 5,190,464 active companies on the UK register, and ranks 27510 5th most used of the 6 codes we track in division 27. 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 27510
396 companies put 27510 first and a further 130, 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 39 per cent of it, and Beckenham alone accounts for 16 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 27510 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: 27510, registered office in Beckenham, incorporated in the last ninety days, which turns a 526 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 27510
How many UK companies use SIC code 27510?
526 active UK companies list 27510 (Manufacture of electric domestic appliances) among their registered SIC codes. Each company may register up to four. Of those, 396 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
Which SIC code fits a control panel or switchgear assembly business?
Most panel builders use 27900. An assembled control panel counts as electrical equipment, and the narrower codes for motors and components rarely match assembly work. Some builders also list an electrical installation code from division 43, because they commission panels on site. Both approaches are common and fine. You select SIC codes yourself and Companies House applies no test of accuracy.
Can changing our SIC code affect R&D tax relief claims?
No. HMRC judges research and development claims on the work you actually did, not the code on the public record. The code does appear on claim forms, and a wildly wrong one can invite questions. Keeping it accurate is sensible housekeeping. Changing it is easy. State the new codes on your next confirmation statement and the public record updates. No approval is needed.
