Introduction to Insurance Broker Organic Growth: What Is A Good Rate?
Insurance broker organic growth tells you whether your brokerage is expanding through its existing business, new clients and stronger client relationships rather than acquisitions. It is one of the most useful measures of underlying commercial performance. Yet a headline growth figure can conceal problems with retention, new business and commission income.
Imagine a brokerage celebrating 12% revenue growth. The managing director expects the sales team to be congratulated. But most of the increase came from higher insurance premiums, while the firm lost several profitable clients and won fewer new accounts. Revenue has risen, but the underlying business may not be getting stronger.
That is why insurance broker organic growth deserves closer attention. Owners need to separate genuine progress from market-driven changes, understand what a good rate looks like and identify the actions that can improve results without buying another firm.
What Is A Good Insurance Broker Organic Growth Rate?
A good underlying growth rate depends on the size of the brokerage, its client mix, market conditions and how growth is measured. There is no single percentage that makes every brokerage successful.
As a practical management guide, sustained mid-single-digit growth can be respectable for an established firm, while high-single-digit or double-digit growth may signal stronger performance. These are illustrative benchmarks, not a published UK industry standard. They must be judged alongside retention, profitability and the influence of insurance pricing.
A firm growing by 6% through additional clients, increased policy penetration and strong renewals may be healthier than one reporting 10% growth largely because premiums increased. For insurance broker organic growth, the source and quality of revenue matter as much as the headline rate. According to MarshBerry’s research into insurance broker organic growth, average firms in its 2024 US benchmarking data achieved 8.7% organic growth, compared with 18.2% for the top-performing group. These figures provide useful context, although they should not be treated as UK industry averages.
For firms considering additional sources of insurance capacity and client solutions, the discussion in Insurance Linked Securities UK: Is The Market Set To Grow? provides a related view of how the wider market may develop.
What should owners compare their growth against?
Compare like-for-like commission and fee income across comparable periods. Segment results by commercial and personal lines, industry, client size and product type. Review both growth and retention over several years rather than relying on a single quarter.
Track the movement in underlying client numbers, policies per client, average revenue per account and new business won. If these measures are deteriorating, a strong reported percentage may be misleading.
Before setting a target for insurance broker organic growth, decide which premium movements and one-off revenues you will include or exclude. Apply the same definition consistently.

How Do You Calculate Insurance Broker Organic Growth?
underlying growth is usually calculated by comparing revenue from the existing business over two periods, excluding the contribution of acquired or disposed businesses and making other adjustments needed for a fair comparison.
For a simple example, suppose a brokerage generated £2 million of comparable commission and fee revenue last year and £2.16 million this year, with no acquisitions or disposals. The increase is £160,000. Divide that by £2 million and multiply by 100. The organic growth rate is 8%.
Organic growth rate (%) = ((current comparable revenue − prior comparable revenue) ÷ prior comparable revenue) × 100.
The calculation becomes more complicated when a firm buys another brokerage, sells a book of business, changes its accounting approach or benefits from unusual commission adjustments. Those effects should be identified before comparing performance.
Should premium inflation be removed?
There is an important distinction between a company’s reported organic revenue growth and its underlying volume-led growth. Some businesses include commission earned from rising premiums in their organic revenue figures because it comes from the existing book. Others analyse growth at constant rates to see how much came from new clients, cross-selling and retained business.
Neither measure should be presented as interchangeable. The most useful insurance broker organic growth dashboard shows reported organic revenue growth and a separate view adjusted for insurance rate movements where reliable data allows.
Which figures belong on the dashboard?
Include opening revenue, revenue lost through cancellations, revenue retained at renewal, new-client revenue, additional sales to existing clients, commission changes and closing revenue. Separate acquired revenue from business generated by the existing operation.
That creates a clearer view of whether Sales Training for Insurance Brokers and other commercial improvements are translating into measurable client outcomes.

What Is The Difference Between Organic Growth And Total Revenue Growth?
Total revenue growth measures the change in a firm’s overall revenue. underlying growth aims to isolate the change generated by the underlying business rather than purchased operations.
Suppose a brokerage starts with £3 million in revenue, adds £300,000 through its existing business and acquires another firm contributing £700,000. Total revenue becomes £4 million, representing growth of roughly 33.3%. But the organic increase from the original business is 10%, before any further comparability adjustments.
This distinction matters when assessing management performance. Acquisitions can increase scale, but they do not automatically prove that existing teams are retaining more clients or winning new business effectively.
Can a brokerage grow overall while shrinking organically?
Yes. A firm could acquire several books of business while losing revenue from its original clients. Total revenue would rise even if the underlying operation were contracting.
That is why insurance broker organic growth should be reviewed alongside acquisition performance rather than buried inside one combined number. Investors, lenders and business owners need to understand what is actually driving results.

What Drives Insurance Broker Organic Growth?
underlying growth comes from a combination of winning suitable new clients, retaining profitable existing clients and increasing the value delivered within established relationships.
There are four useful commercial levers: new business, retention, cross-selling and account development. A brokerage that manages all four systematically is less dependent on a single salesperson or a favourable insurance market.
Winning more of the right new clients
More enquiries do not always mean more revenue. Firms need to understand which sectors they serve well, why customers choose them and where prospects drop out of the sales process.
Measure qualified opportunities, meetings held, quotations issued, conversion rates and revenue won. Review the reasons for lost business, especially when prospects say the premium is too high or they need time to think.
Retaining existing accounts
Retention protects the starting revenue base. When a brokerage loses clients, new business must first replace the income that has disappeared before it can create net growth.
Review renewal preparation, claims service, communication and the quality of advice throughout the year. Insurance broker organic growth becomes harder when client relationships are only revisited shortly before renewal.
Increasing share of wallet
Existing customers may have risks that are insured elsewhere or not properly reviewed. Relevant additional cover can improve client protection while increasing brokerage income.
Health and employee-benefit needs can also shape account development. The article Private Medical Insurance UK: Why Is Demand Rising? explores one area brokers may need to understand when reviewing suitable protection.
Cross-selling should start with an assessment of the client’s needs, not a target to sell an unnecessary policy. Insurance Broker Sales Coaching can help teams ask better questions and uncover gaps without pressuring customers.

How Does Client Retention Affect Insurance Broker Organic Growth?
Retention has a direct effect on insurance broker organic growth because lost commission and fee income must be replaced before a firm can show a net increase.
Consider a brokerage with £1 million of recurring revenue. If it loses £100,000 at renewal and wins £120,000 of new business, net growth is only £20,000, or 2%, assuming no other changes. Improving retention so that only £50,000 is lost would increase net growth to 7% with exactly the same new business performance.
This is why a brokerage can improve growth without increasing the number of leads. Protecting valuable client relationships may produce a faster result than adding more activity at the top of the funnel.
What should retention reporting include?
Measure client retention by number of accounts and revenue retention by the income retained. They tell different stories. Losing one large commercial account can have a greater financial impact than losing several small policies.
Record the reasons clients leave. Separate price objections from service problems, business closures, changing needs and competitive displacement. Then review what could realistically have been prevented.
How can brokers reduce avoidable losses?
Begin renewal discussions early, explain market changes and review emerging risks before sending a quotation. Make it easy for customers to contact the right person and resolve issues promptly.
Teams using In-House Insurance Sales Training can practise renewal conversations that focus on outcomes rather than simply defending a premium increase.
For underlying growth, retention is not merely a service metric. It is a commercial measure that deserves attention at management meetings.

Do Insurance Premium Increases Count As Organic Growth?
Premium increases can contribute to reported insurance broker organic growth when commission is calculated as a percentage of premiums on an existing book. However, that does not necessarily mean the brokerage has become better at selling or retaining customers.
Imagine a client whose premium rises from £10,000 to £12,000. At a constant 15% commission, brokerage income rises from £1,500 to £1,800 without any additional policy or new customer. That £300 may appear in reported organic revenue, depending on the firm’s definition.
It is therefore useful to separate rate-driven commission growth from underlying client and coverage growth. Otherwise management may overestimate commercial performance during a hard insurance market.
Changes in liability and claims arrangements can affect specialist markets too; Automated Vehicle Insurance UK: Who Pays After A Crash? examines questions relevant to motor insurance distribution.
What happens when insurance rates soften?
Falling premiums can reduce commission income even when the brokerage retains its customers and policy count. Teams may need to generate more new business or expand suitable cover to maintain revenue.
underlying growth analysis should therefore include changes in policy count, insured exposures and commission rates wherever possible. That gives owners a more balanced picture than revenue alone.

How Can Insurance Brokers Improve Organic Growth Without Acquisitions?
Improving insurance broker organic growth requires a repeatable commercial process, not simply telling producers to sell more. Management needs to identify where revenue is leaking and which changes are most likely to improve results.
Build a clearer new-business proposition
Choose the client segments where the brokerage can demonstrate relevant expertise. Explain the practical value of advice, claims support and risk understanding rather than relying on generic promises of good service.
In personal lines, the changing economics of claims can affect which products and clients a brokerage chooses to serve. See Pet Insurance UK: Why Are Claims Costs Still Rising? for an example from pet insurance.
Improve conversion before buying more leads
Review what happens after the first enquiry. Are meetings focused on the client’s real concerns? Are quotations explained clearly? Does the team agree a next step, or does the opportunity disappear after the proposal?
Improving conversion can increase underlying growth without increasing marketing expenditure. Corporate Sales Training for Insurance Brokers can help teams strengthen these conversations while keeping the approach consultative.
Make account reviews meaningful
Do not treat every review as an opportunity to sell another policy. Use it to understand business changes, new exposures, claims experiences and protection gaps. Additional revenue should follow genuine client needs.
Coach consistently and measure results
Review a small set of leading indicators each month: qualified pipeline, meeting-to-quotation conversion, quotation-to-win conversion, retention and additional revenue from existing accounts.
Insurance broker organic growth becomes easier to manage when coaching focuses on observable behaviours and specific opportunities rather than vague demands for more activity.

How Does Insurance Broker Organic Growth Affect Business Valuation?
underlying growth can influence the attractiveness and value of a brokerage because buyers want evidence that revenue can expand without continual acquisitions.
However, growth alone does not determine a valuation. Profit margins, recurring income, client concentration, retention, operational risk, management dependence and the quality of financial reporting also matter.
A brokerage with strong underlying growth but poor profitability may be less attractive than a slightly slower-growing firm with dependable earnings and excellent client retention.
Distribution strategy is another factor buyers may examine. Embedded Insurance: Is This The Future Of Distribution? looks at how insurance offered within other customer journeys may change access to business.
Why do buyers examine the source of growth?
Buyers want to know whether the current performance is repeatable. Revenue created by improved conversion and durable customer relationships may be viewed differently from revenue generated mainly by a temporary rise in market premiums.
Consistent insurance broker organic growth, supported by clear management information, can strengthen confidence in future cash flows. It does not guarantee a particular valuation multiple.
What should owners prepare before a sale?
Maintain a clear bridge from opening to closing revenue, showing new business, lost accounts, rate changes, cross-sales and acquisition effects. Track performance by client cohort and identify major customer dependencies.
Well-documented results allow a potential buyer to test the firm’s claims rather than relying on an optimistic headline percentage.

Why Does Insurance Broker Organic Growth Slow Down?
Insurance broker organic growth can slow when new-business conversion weakens, clients leave, market rates soften or teams become too reliant on a small number of relationships.
Sometimes the problem is not effort but process. Producers may spend too much time servicing accounts to develop new opportunities. Other firms generate leads but fail to follow them up consistently.
Specialist risks can also create opportunities for brokers with the right expertise. Data Centre Insurance: Can Cover Keep Up With AI Growth? considers the challenges of providing cover to expanding digital infrastructure.
Warning signs to investigate
- Falling numbers of qualified opportunities.
- Longer periods between enquiry and quotation.
- More deals lost without a clear reason.
- Lower revenue retention despite stable client numbers.
- Heavy dependence on a handful of large accounts.
- Inconsistent cross-selling and account reviews.
underlying growth reporting should identify these issues before they become visible in annual revenue figures. A declining pipeline today can become a disappointing growth result several months later.
Regular Insurance Broker Sales Workshops can help teams address specific weaknesses, practise difficult conversations and agree measurable changes.

Frequently Asked Questions About Insurance Broker Organic Growth
1. What is a good organic growth rate for an insurance broker?
A good insurance broker organic growth rate depends on the business, market conditions and reporting definition. As an illustrative guide, sustained mid-single-digit growth can be respectable for an established brokerage, while high-single-digit or double-digit growth may indicate stronger momentum.
But the percentage needs context. Growth driven by new clients and improved retention may be more sustainable than growth driven mainly by higher premiums. Compare performance over several years, alongside profit and revenue retention. For a meaningful comparison, use the same revenue definition year on year, exclude acquisitions and review how much of the increase came from insurance rate changes.
2. How do you calculate organic growth for an insurance brokerage?
Start with comparable revenue from the existing business for the current and previous periods. Subtract prior-period revenue from current-period revenue, divide the difference by prior-period revenue and multiply by 100.
For example, growth from £1 million to £1.08 million is 8%, assuming the revenue is comparable and no acquisition or disposal adjustments are required. underlying growth calculations should clearly disclose how rate movements and unusual items are treated. Keep a written reconciliation of acquisitions, disposals, one-off commissions and other adjustments so another person can reproduce the calculation.
3. What is the difference between organic growth and total revenue growth?
Total revenue growth includes the change in all reported revenue, including income added through acquisitions. Organic growth focuses on the underlying existing operation, normally excluding acquired and disposed businesses.
A brokerage can therefore report rapid total growth while its original client book is flat or declining. Both measures are useful, but they answer different questions about performance. Report both figures together so management can distinguish expansion through purchases from performance of the original book.
4. How can an insurance broker grow organically?
Insurance broker organic growth can improve through winning more suitable clients, retaining existing accounts, cross-selling relevant protection and increasing conversion rates.
Start by measuring where revenue is won and lost. Then strengthen the sales process, improve renewal preparation and coach teams on the conversations that influence client decisions. Buying more leads is not always the first or best solution. Prioritise improvements by their financial effect: lost renewal revenue, quote-to-bind conversion and the contribution from additional suitable policies.
5. What drives organic growth in an insurance brokerage?
The main drivers are new-client revenue, retained income, additional business from existing clients and changes in commissions or fees. Insurance market pricing can also affect reported organic revenue.
For a useful view of underlying growth, separate underlying client and policy development from premium rate effects. This helps management understand whether growth is repeatable. A revenue bridge showing opening income, losses, new clients, additional cover and rate effects makes these drivers easier to explain.
6. How does client retention affect insurance broker organic growth?
Client retention protects the revenue base. Every lost account creates a gap that new business must fill before the brokerage can achieve net growth.
For example, reducing annual revenue losses from £100,000 to £50,000 improves the net result by £50,000 even if new-business performance remains unchanged. Measure both client retention and revenue retention because losing one major account can outweigh several smaller wins. Check retention by both customer count and commission-and-fee income, and investigate the causes of departures before changing renewal processes.
7. Do insurance premium increases count as organic growth?
They can. Where a brokerage earns percentage-based commission, higher premiums on existing policies can increase reported revenue without any acquisition. Whether that appears in the published organic figure depends on the reporting definition.
However, insurance broker organic growth caused by premium inflation should not be confused with stronger new-business conversion or retention. A separate constant-rate analysis can help explain the difference. Show the reported growth figure alongside a rate-adjusted measure where reliable data exists, and explain any assumptions.
8. How does organic growth affect the value of an insurance brokerage?
Sustained organic growth may make a brokerage more attractive to buyers because it provides evidence of an expanding underlying business. It can support confidence in future revenue and earnings.
Valuation also depends on profitability, retention, recurring income, client concentration and business risk. A strong insurance broker organic growth percentage does not automatically produce a high sale price. A buyer may request several years of comparable revenue bridges, retention data and evidence that growth does not depend on a handful of clients or producers.
9. Why does insurance broker organic growth slow down?
Growth can slow because fewer suitable prospects enter the pipeline, conversion rates fall, clients leave, commission income declines or insurance rates soften.
Review each cause separately. A brokerage with strong retention but weak new business needs a different response from one that wins clients consistently but loses too many at renewal. Clear diagnosis should come before new targets. Compare pipeline creation, quotation speed, win rates and renewal losses across successive periods to locate the main bottleneck.
10. How can insurance brokers grow organically when insurance rates are falling?
When premiums fall, percentage-based commission may decline even if the client base stays stable. underlying growth then depends more heavily on retaining clients, winning new accounts and identifying genuine additional protection needs.
Focus on client value, stronger prospect qualification, effective follow-up and account reviews. Measure client numbers, policy penetration and constant-rate performance so teams can see progress that may be hidden by falling market prices. Avoid responding to softer rates with unsuitable cross-selling or indiscriminate fee increases; sustainable growth still depends on fair customer outcomes.

Final Thoughts: How Can Brokers Build Sustainable Growth?
Insurance broker organic growth is not simply a percentage to celebrate at the end of the year. It shows whether the underlying business is developing through stronger relationships, relevant new clients and consistent commercial execution.
Start with a clear definition, measure the sources of revenue change and distinguish genuine client-led progress from movements in insurance premiums. Then focus on the practical work: better conversations, stronger renewals, more effective follow-up and useful account reviews.
A brokerage that understands its numbers can make better decisions about where to invest time and money. Sustainable insurance broker organic growth comes from improving the business clients already experience, not relying on acquisitions or a favourable market to disguise weaknesses.
