How to Spot High-Quality Leads in UK Company Formation Data: 7 Signals That Predict Real Businesses

Specific SIC code selection

The Standard Industrial Classification (SIC) code a company chooses at registration is the single best indicator of whether it intends to trade — and what it plans to do.

Strong signal: Specific, operational SIC codes like 56101 (licensed restaurants), 62012 (business and domestic software development), or 43210 (electrical installation). These codes describe real activities that require premises, staff, and suppliers.

Weak signal: Generic catch-all codes like 74909 (other professional activities not elsewhere classified), 64209 (activities of other holding companies), or 70100 (activities of head offices). Companies using these codes are often dormant vehicles, holding structures, or formations where the founder did not know what to select.

Filtering out holding company SIC codes alone can remove 15–20% of low-quality registrations from your lead list.

Registered address type

Where a company is registered tells you a lot about how serious it is.

Strong signal: A unique commercial address, a high street location, or an address that does not appear for dozens of other companies. This suggests the founders have actual premises or a genuine home office.

Weak signal: Formation agent addresses — the most common being 20-22 Wenlock Road, London N1 7GU, 71-75 Shelton Street, London WC2H 9JQ, and dozens of similar virtual office addresses. Companies registered at formation agent addresses are more likely to be non-trading, overseas-owned, or dormant.

This does not mean every company at a formation agent address is worthless — many legitimate businesses start there. But statistically, the conversion rate from formation agent addresses is significantly lower than from unique addresses.

Director occupation and nationality

Companies House records include each director's stated occupation and nationality. Both carry useful signals.

Strong signal: A director with a specific, relevant occupation — for example, "chef" for a restaurant company, "electrician" for an electrical contractor, or "software developer" for a tech company. This indicates someone with domain expertise starting a business in their field.

Weaker signal: Generic occupations like "director", "businessman", or "consultant" — or no occupation listed at all. While these are not necessarily bad, they correlate with a higher proportion of dormant or speculative formations.

Director nationality can also indicate market relevance. If you are selling UK-based services (insurance, telecoms, banking), UK-resident directors are more likely to be immediate buyers than overseas directors who may be using a UK company for international structuring purposes.

Number of directors and officers

The number of people appointed at incorporation is a useful proxy for business seriousness.

Strong signal: Two or more directors, or a director plus a company secretary. This suggests a genuine partnership or a business that has had enough planning to involve multiple people from day one.

Neutral signal: A single director is the most common setup and perfectly normal for small businesses — it is neutral rather than negative. However, single-director companies with a formation agent address and a generic SIC code are far more likely to be dormant.

Bonus signal: If a company appoints a person with significant control (PSC) with more than 75% shareholding and a specific occupation, it is almost certainly a founder-led trading business.

Company name structure

The company name itself carries signal, though it requires pattern recognition rather than simple filtering.

Strong signal: Names that describe a service or trade — for example, "Manchester Plumbing Solutions Ltd", "Brightside Digital Marketing Ltd", or "The Green Kitchen Café Ltd". These names suggest a company that plans to trade under its registered name and has thought about its market positioning.

Weaker signal: Generic names like "JKS Holdings Ltd", "Property 247 Ltd", or names with random strings of characters. Names containing "Holdings", "Investments", "Property", "Assets", or "Group" (without other indicators) are disproportionately likely to be holding companies rather than trading businesses.

Important caveat: many excellent businesses have generic names. This signal works best as a tiebreaker combined with other data points, not as a primary filter.

Share capital declared

When a company is formed, it declares its initial share capital. While most UK companies are formed with the minimum £1 share capital (or 100 shares at £1 each), some choose to declare higher amounts.

Strong signal: Share capital above £1,000 suggests the founders are investing real money from the start. Capital above £10,000 is a strong indicator of a serious venture, possibly externally funded.

Neutral signal: The standard £100 (100 shares at £1) is so common that it carries no real signal either way. Do not filter these out — most genuine businesses use this structure.

This field is available in Companies House data but is often overlooked by lead providers. It can be particularly useful for identifying companies that are likely to have higher budgets.

Incorporation date relative to tax year

When a company is formed within the UK financial calendar matters. Companies incorporated in March and early April often represent genuine new businesses timed around the tax year end. Founders who have been self-employed often incorporate before 6 April to optimise their tax position for the new year.

Companies formed in January often reflect New Year resolutions and new ventures. The September–October period sees another spike from post-summer launches.

Conversely, companies formed in bulk on the same day by the same formation agent (visible through identical registered addresses and sequential company numbers) are more likely to be pre-formed shelf companies rather than genuine new businesses.
