Can You Search the FCA Register by Company Size?

Can you search the FCA Register by company size? Not reliably through the public FCA Register alone.

The FCA Register is the official place to check regulated firms, individuals, permissions, status and appointed representative relationships. It is essential for verification. But company size is not a simple commercial filter in the public Register.

That matters if your question is not “is this firm authorised?” but:

• Which FCA-regulated firms are small, mid-sized or large?
• Which financial advice firms have enough adviser capacity for our target profile?
• Which regulated firms look large enough for an enterprise sales motion?
• Which smaller firms might suit a regional campaign, recruitment search or acquisition thesis?
• Which principal firms have sizeable appointed representative networks?

Those are commercial research questions. They need size signals, not just regulatory records.

The FCA Register can be one input, but it normally has to be combined with enrichment from sources such as Companies House, adviser or key-person counts, appointed representative relationships, office and branch signals, websites, and sector-specific data such as AUM or AUA where available.

Why company size is not a simple FCA Register field

Company size is not the same thing as regulatory status.

The FCA Register can help you check whether a firm is authorised, what permissions it holds, whether it has appointed representatives, and which individuals or roles may be linked to the record. It was not designed as a commercial segmentation database for sales, marketing, M&A, recruitment or market research teams.

That is why size is hard to search directly.

A large firm and a small firm may hold similar permissions. A two-adviser financial planning business and a large advice group may both appear in the regulated universe, but the Register record alone may not give you the full commercial picture. A principal firm with many appointed representatives may look different from a directly employed multi-office firm. A specialist investment firm may have a small employee base but still manage or advise on substantial assets.

So the practical answer is: use the FCA Register as the regulated-firm starting point, then enrich it. The same logic applies to other commercial filters. If you are trying to search the FCA Register by company type, permissions alone do not always tell you whether a firm is a wealth manager, hedge fund manager, mortgage broker or corporate finance adviser. For company size, the problem is similar: the official record is valuable, but the size signal usually lives across several fields and sources.

For a broader view of Register limitations, see what you can and cannot find on the FCA Register.

What size signals can you use instead?

There is no perfect single signal for firm size. The best workflow combines several indicators and treats each one as a clue. Depending on the sector and use case, useful signals can include:

• Adviser, approved-person, Directory Person or key-person counts.
• Companies House accounts, filing type, company age and group structure.
• Appointed representative relationships and network size.
• Office, branch and location signals.
• Website team pages, leadership pages and service-line evidence.
• Headcount estimates where available.
• AUM or AUA for advice, wealth and investment firms where available.
• Ownership, controller and director information.
• Category or sector classification.

Each signal has limitations. A small team may run a valuable specialist firm. A group structure can hide actual scale. Companies House filings may be abbreviated or may not expose the commercial detail a researcher wants. But together, these signals can turn a raw FCA regulated firm list into a practical size based market view.

Signal 1: adviser, approved-person or key-person count

For some regulated sectors, person counts are one of the strongest size clues.

In the financial advice market, the FCA’s 2025 advice-market survey uses adviser numbers and firm-size bands as part of its sector analysis. The report notes that it draws on sources including the FS Register, and it analyses adviser capacity, small, medium and large firms, and the role of larger groups in the advice market.

That does not mean every FCA-regulated sector can be measured cleanly by adviser count. It also does not mean a public Register search gives you a neat “show firms with 10 to 50 employees” filter.

But for advice, wealth and some intermediary markets, counts of advisers, approved people, Directory Persons or other key individuals can help distinguish:

• Solo or very small firms.
• Local multi-adviser businesses.
• Regional firms.
• Larger advice groups.
• Principal firms or networks with broader regulated relationships.

The important thing is to use the right person signal for the sector. Adviser count may be highly relevant for IFA and financial planning research. It may be less useful for other regulated firm types where scale is better inferred from permissions, filings, offices, assets, controllers or operating model.

Signal 2: Companies House filings and financials

Companies House data can add useful company size context around an FCA Register record.

Depending on the firm and filing availability, useful fields may include:

• Company age and incorporation date.
• Filing type and accounts category.
• Balance sheet indicators.
• Turnover where disclosed.
• Employee-related disclosures where available.
• Directors and officers.
• Persons with significant control.
• Registered office changes.
• Group structure and parent or subsidiary relationships.
• Dormant, dissolved or liquidation indicators.

This is helpful because the FCA Register and Companies House answer different questions.

The FCA Register tells you about the regulated record. Companies House can help you understand the legal entity around that record. For sales, M&A, compliance, recruitment and market research workflows, the join between those two sources can be more useful than either source alone.

There are limitations. Smaller companies may file less detailed accounts. Group structures can make a single operating business hard to read. A regulated brand may not map cleanly to one Companies House entity without matching work. Financials may lag. Some important commercial signals may not be in filings at all.

So Companies House data should be treated as enrichment, not a perfect company-size answer.

Signal 3: offices, branches, appointed representatives and networks

In regulated financial services, size is not always just employee count.

For some firms, scale shows up in network structure.

Examples include:

• A principal firm with many appointed representatives.
• An advice group with regional offices.
• A broker network with multiple trading names.
• A wealth or advice business with several branches.
• A firm whose group structure includes multiple regulated entities.
• A distribution or intermediary network where relationships matter more than one legal entity.

Appointed representative relationships can be particularly useful because they show regulated connections between firms. A principal with a large appointed representative network may have a different commercial footprint from a directly authorised firm with a small office, even if a simple employee-count estimate would miss that distinction.

Office and branch signals can also help. A multi-location firm may be more relevant for territory planning, regional campaigns, acquisition mapping or recruitment than a firm operating from one location. But location count should still be interpreted carefully. Some firms operate nationally with a small central team. Others have legacy office pages that overstate current activity.

The point is to build a size view from the shape of the firm, not from one brittle field.

Signal 4: website and team signals

Website evidence can be useful when structured data is thin.

A firm’s website may show:

• Team size.
• Adviser or consultant profiles.
• Office pages.
• Leadership and board information.
• Service lines.
• Client segments.
• Recruitment activity.
• Regional coverage.
• Specialist propositions.
• Group brands or trading names.

This is especially useful when the FCA record does not make the firm’s commercial profile obvious. A website can help distinguish a local advice firm from a national consolidator, a specialist investment boutique from a broad financial planning firm, or a principal network from a single-location business.

Website signals are qualitative, so they should not be treated as exact size metrics. A polished website does not prove a large firm. A minimal website does not prove a small one. Some firms have outdated pages, thin public information or brand structures that obscure the underlying regulated entity.

But when website signals are combined with FCA data, Companies House data, person counts and relationship data, they can materially improve company-size segmentation.

When company size matters

Company size matters because different teams use FCA-regulated firm data for different decisions.

For sales teams, size can shape territory planning, account prioritisation, outreach strategy and sales motion. A small directly authorised firm may need a different message from a national group or a principal network.

For marketing and ABM teams, size helps define audience segments. A webinar, event, campaign or account-based programme may need to target firms by scale, geography, sector and commercial fit rather than regulatory status alone.

For M&A and PE teams, size is often part of the acquisition thesis. Buyers may want smaller succession-led firms, larger platform opportunities, regional consolidators, or firms that fit a particular adviser, office, AUM or AUA profile.

For compliance, legal and vendor-risk teams, size can affect monitoring priority. A larger principal network, multi-entity group or fast-changing firm may need different review logic from a small low-risk watchlist item.

For recruitment teams, size can shape search strategy. A firm with multiple advisers, offices or growth signals may be more relevant than a firm that simply appears in a broad regulated-firms list.

For market research teams, size helps turn a list into a market map. It supports segmentation, benchmarking and trend analysis across the UK regulated financial services market.

How enriched FCA data makes size filtering practical

Enriched FCA data makes size filtering practical by joining the official regulated-firm record with commercial context.

Distos starts with FCA-regulated firm data, then enriches it with sources and signals such as Companies House information, websites, owners, controllers, directors, appointed representatives, permissions, categories, headcount and alerts. For relevant sectors, fields such as AUM or AUA can also support size and market-fit analysis where available.

That creates a more useful workflow than searching the public Register one firm at a time.

Instead of asking, “Can I find size in this individual Register record?”, a team can ask:

• Show me FCA-regulated advice firms in a certain size band.
• Find smaller firms that match an acquisition or succession thesis.
• Identify larger regulated firms for enterprise sales or ABM.
• Segment firms by category, status, people, Companies House context and market fit.
• Build a watchlist and monitor changes over time.
• Export a target universe for research, sales, marketing or compliance review.

For advice and wealth use cases, the Distos UK IFA firms database is a natural starting point.

For sales and marketing teams, Distos can help to supply quaity financial services data for lead generation. For buyers, consolidators and deal teams, Distos can turn FCA data into a M&A deal sourcing pipeline.

If you need to filter FCA regulated firms by size, segment, status or market fit, book a demo and bring a target profile. The most useful demo question is specific: for example, “show me mid-sized IFA firms in this region”, “find smaller advice firms that may fit an acquisition thesis”, or “build a target list of larger regulated firms for this sales motion.”

What not to assume from company size signals

Size signals are useful, but they can mislead if they are treated as proof.

Do not assume that:

• A small headcount means a low-value firm.
• A large adviser count automatically means a good commercial target.
• A firm with few visible staff has little AUM or AUA.
• A Companies House filing tells the whole operating story.
• A principal firm’s own headcount captures the scale of its appointed representative network.
• One office means one local market.
• A group structure is obvious from the FCA Register alone.

The stronger workflow is to combine signals, document assumptions and refresh the data when it matters.

For example, an M&A team might combine adviser count, director age, Companies House filings, ownership context, website evidence and AUM or AUA where available. A sales team might combine sector, permission, headcount, location, technology fit and company category. A compliance team might combine status, permissions, appointed representative relationships, controller changes and watchlist priority.
