The UK SIC Code List contains the Standard Industrial Classification (SIC) codes used to categorise businesses according to their primary economic activity. These classifications are widely used by Companies House, the Office for National Statistics (ONS), lenders, insurers and businesses seeking to identify companies within specific industries.
For marketing managers, sales teams and business owners, SIC codes provide a practical way to identify companies operating within particular industries. They are commonly used for market research, competitor analysis, prospecting and business segmentation and B2B data.
This guide explains how SIC codes work, how to find a company’s SIC code, how businesses use SIC classifications, and includes access to the complete UK SIC Code List.
For organisations using SIC codes for prospecting, SIC classifications are often combined with additional business information such as company size, turnover and decision-maker data to create more targeted B2B marketing campaigns.

What is a UK SIC Code?
A SIC code, short for Standard Industrial Classification, is a five-digit code used to classify businesses by their primary economic activity.
In the UK, SIC codes are used by Companies House, government departments, and businesses to identify industry sectors.
When incorporating, businesses must select at least one SIC code from the Companies House SIC codes list that accurately reflects their activities. Companies operating in multiple sectors frequently choose more than one code. Selecting an inaccurate SIC code can lead to compliance issues, as the information provided to Companies House is used by HMRC and other government bodies for regulatory and statistical purposes.
Therefore, businesses should consistently verify and update their SIC codes as their activities change, in line with Companies House requirements, especially in light of new financial penalty regulations that came into effect in May 2024.
Business Data Prospects maintains one of the UK’s largest commercially available B2B company databases. In our experience, SIC codes are one of the most effective starting points for market segmentation, however they deliver significantly better results when combined with turnover, employee count and decision-maker data.
Are SIC Codes Important?
With the basics of business SIC codes covered, we will now review the official UK SIC Code List and its applications.
The UK SIC Code List is the official classification system maintained by the Office for National Statistics (ONS) and used by Companies House.
The current framework, UK SIC 2007, includes hundreds of classifications covering nearly every industry in the UK economy. The SIC framework is reviewed periodically, with major updates occurring to reflect changes in the UK economy and emerging sectors. UK SIC 2007 is the latest version in use, and users should check periodically to ensure they are referring to the most up-to-date classification.
These classifications span agriculture, manufacturing, professional services, technology, healthcare, and financial services.
Businesses regularly use SIC codes to:
- Identify companies operating within a specific sector.
- Build targeted B2B marketing campaigns.
- Analyse markets and industries.
- Conduct competitor research.
- Segment business databases.
- Support compliance and reporting requirements.
- Improve prospect targeting.
SIC codes are essential for market research, business intelligence, prospecting, risk assessment, and regulatory reporting.
How to Find a Company’s SIC Code
Identifying a company SIC code from the SIC code list below is a simple procedure.
Step 1: Search Companies House
Visit the Companies House website and search for the company name.
Step 2: Open the Company Record
Select the relevant company from the search results.
Step 3: Review SIC Activities
The company record will display one or more SIC codes together with descriptions of the business activities undertaken.
Step 4: Verify Current Activities
As businesses evolve, it is important to review the latest filings and company information to ensure the SIC code accurately reflects current operations. If your company’s activities change and you need to update your SIC code, you can do so through Companies House. Here is how to update your SIC code:
- Log in to your Companies House WebFiling account.
- Select your company and go to ‘File for this company.’
- Choose ‘Change of company details’ and select to update your SIC code.
- Enter the updated SIC code(s) that best describe your current business activities.
- Submit the changes online. According to Companies House, there is an online fee of £50 to update your SIC code, which can only be done by filing a confirmation statement. Changes appear on the register within 24 hours. It remains important to update your SIC code as soon as your business activities change to retain compliance with Companies House requirements.
Most Common SIC Codes in the UK
According to the Office for National Statistics, there are hundreds of Standard Industrial Classification (SIC) codes in use, but some codes from the SIC code list 2007 are especially prevalent among UK businesses. Examples of commonly used SIC codes include:
- 62012 for business and domestic software development
- 56101 for licensed restaurants
- 70229 for management consultancy activities (other than financial management).
- 71129 Other engineering activities (not including engineering design for industrial process and production)
- 86210 General medical practice activities
- 41202 Construction of domestic buildings
- 73110 Advertising agencies
- 47910 Retail sale via mail order houses or via Internet
- 82990 Other business support service activities n.e.c.
In comparison, across BDP’s UK company database, the most frequently selected SIC classifications are 70229, 62012 and sic 82990.
These examples cover key sectors such as technology, hospitality, professional services, healthcare, construction, marketing, and e-commerce. Including these codes can help you quickly identify relevant sectors for your business or research. These sectors account for a significant share of UK business activity and are frequent targets for B2B marketing.
For example, a software development company planning to apply for government funding might use SIC code 62012 when registering with Companies House to ensure it is correctly classified for eligibility purposes. Alternatively, a marketing agency launching a targeted campaign to private medical practices could use SIC code 86210 to compile a list of qualified prospects. Using the correct SIC code not only maintains regulatory compliance but also helps businesses reach the right audiences for their products and services.
How to Identify the Right SIC Codes for Your Marketing
One of the simplest ways to identify relevant SIC codes is to review your existing customer base.
Start by listing your best customers and looking up their SIC codes using Companies House. In many cases, a pattern will emerge, helping you identify the industries most closely aligned with your products or services.
For example, a software provider may discover that many of its existing clients share SIC codes relating to manufacturing, engineering or similar business services. These classifications can then be used as the starting point for prospecting and market segmentation.
This approach is often more effective than selecting SIC codes based on assumptions, as it uses your current customer base to identify sectors that already buy from businesses like yours.
SIC Codes vs NAICS Codes
Businesses with international operations often encounter both SIC and NAICS classifications.
While both SIC code lists in the UK and NAICS codes to represent international businesses, these are used to classify businesses by industry and support government and business activities, there are important differences UK and international organisations should be aware of. The SIC (Standard Industrial Classification) system is the traditional UK and European classification system, originally created in the 1930s and still in active use in the UK. The NAICS (North American Industry Classification System) was introduced in 1997 by the United States, Canada, and Mexico to create a shared business classification standard for North America.
Key differences between SIC and NAICS codes:
- Structure: SIC codes are typically 4 or 5 digits long, while NAICS codes use a more detailed 6-digit structure, permitting more specific industry categorisation.
- Geographic scope: SIC codes are used primarily in the UK and the European Union, whereas NAICS codes are standard in the United States, Canada, and Mexico.
- Industry coverage: NAICS is updated more frequently to reflect new and emerging industries, while SIC has a more established focus. Some business activities may be classified differently depending on the system used.
- Compatibility: The two systems are not directly interchangeable, so companies operating internationally must reference the appropriate codes for each territory.
Knowing these differences helps secure accuracy in compliance, reporting, and international business operations. While the objectives are similar, the classifications are not interchangeable.
How Businesses Use SIC Codes
SIC codes are fundamental for organisations seeking to target specific industries.
Common uses include:
Market Segmentation
Businesses can group organisations by industry sector and adapt marketing campaigns to each segment.
Lead Generation
Sales teams use SIC codes to identify companies that match their ideal customer profiles.
Market Analysis
Researchers use SIC classifications to analyse trends, identify growth sectors, and assess economic performance.
Competitor Identification
Companies can quickly identify competitors within the same industry classifications.
Financial Risk Assessment
According to the UK government, Companies House applies a condensed version of the SIC codes from the Office for National Statistics to classify businesses, which can be used by banks, insurers, and lenders during underwriting and risk assessment.
The Limitations of SIC Codes
While SIC codes help categorise business activities, the UK government notes that Companies House uses a simplified list, so these codes should not be relied upon alone for complete risk assessment.
Analysis of over 4 million UK company records held by Business Data Prospects found that 18% of businesses are associated with more than one SIC classification.
When clients initially request prospect lists based solely on SIC codes, we typically recommend additional qualification criteria, such as company size, geography, and decision-maker role, or further market research. SIC codes identify industry sectors, but they rarely identify the businesses most likely to become customers.
Companies Self-Select Their SIC Codes
Businesses select their own classifications from the SIC code list during incorporation and may not always choose the most accurate option. To help ensure you select the most suitable SIC code, commence by reviewing the official descriptions of each code and selecting those that best capture your main business activities. Consider your core products or services, where the majority of your revenue comes from, and which code is most frequently used by similar businesses. For companies with complex or changing activities, it can be helpful to consult industry associations, use multiple codes where applicable, or obtain guidance from a professional advisor. Always update your SIC codes if your primary business focus moves to retain compliance.
Businesses Change Over Time
A company may retain its original SIC code even if its activities change significantly.
Broad Classifications Can Reduce Accuracy
Many organisations select broad codes, which provide limited insight into their products or services.
SIC Codes Alone Do Not Indicate Buying Intent
Knowing a company’s industry is helpful, but it does not reveal:
- Company size
- Employee numbers
- Turnover
- Development path
- Technology adoption
- Decision makers
- Purchasing requirements
Therefore, effective B2B targeting combines SIC codes with additional business intelligence.
How BDP Builds Industry-Targeted Prospect Lists
At Business Data Prospects, we go beyond basic SIC code selection by using a multi-criteria targeting process. We integrate SIC classifications with additional company data, including size, location, turnover, and information about decision-makers. This method is customised to each client’s needs, ensuring your prospect lists are highly relevant, precise, and aligned with your business objectives.
Our strategy combines:
- Relevant SIC classifications
- Company size filters
- Employee counts
- Turnover bands
- Geographic targeting
- Director and decision-maker identification
- Recent company activity
This specific, multi-layered methodology ensures segmentation is precise and closely aligned with business objectives, clearly distinguishing our approach from the limitations of SIC-only methods. By combining additional data points, such as company size, location, turnover, and key decision-maker details, we provide deeper insight and greater relevance.
This approach results in a more relevant and commercially valuable pool of prospects.

How BDP Uses SIC Codes
SIC codes form the foundation of many B2B targeting projects, but they are only one layer of the selection process. Our analysts combine SIC classifications with company size, turnover, location and key decision-maker information to create more precise prospect selections for clients.
Using SIC Codes for B2B Prospecting
SIC codes are often used as the starting point for B2B prospecting because they allow businesses to identify companies operating within specific industries.
However, SIC codes alone rarely provide enough information to build a highly targeted prospect list. Businesses typically combine SIC classifications with additional criteria such as employee numbers, turnover, location and decision-maker information.
For example, a company targeting UK software firms may begin with SIC code 62012 and then refine results by company size, geography or senior job title. This approach produces a more focused and commercially relevant prospect selection.
Complete SIC Code List
The complete UK SIC Code List includes hundreds of classifications organised into major divisions.

Frequently Asked Questions
What does SIC stand for?
SIC stands for Standard Industrial Classification.
Are SIC codes mandatory?
Yes. Limited companies registered with Companies House must select at least one SIC code that describes their business activities.
Can a company have more than one SIC code?
Yes. Many businesses operate in more than one sector and may therefore be assigned multiple SIC codes by Companies House.
According to Companies House, the SIC codes listing was last updated on 17 November 2025.
According to Companies House, companies can update their SIC codes via the confirmation statement when their activities change. Even dormant or non-trading companies must supply a SIC code, and it is important that the code accurately reflects the company’s current activities.
According to Companies House, SIC codes serve as indicators of a company’s main business activity, but they do not always fully capture all aspects of a company’s operations.
Can SIC codes be used for B2B marketing?
Companies House uses a shortened list of SIC codes provided by the Office for National Statistics, which businesses and marketers can use to broadly identify potential customer industries, though the classification may not be exhaustive.
Yes. SIC codes are widely used for segmentation, lead generation and market analysis, although they are most effective when combined with additional company intelligence.
Conclusion
The UK SIC Code List provides a standardised system for classifying businesses according to their economic activities.
Whether you are conducting market research, building prospect lists, analysing industries or recognising potential customers, SIC code lists remain one of the most valuable business classification tools available.
By combining SIC codes with key company data such as size, location, turnover, and decision-maker information, businesses can develop highly targeted strategies. This comprehensive approach improves market segmentation, delivers deeper insights, and enables more informed business decisions and more effective prospecting.
