Actuaries work across areas such as pricing, reserving, capital modelling, risk management, and financial reporting. They translate complex uncertainty into practical recommendations, supporting decision-making on product design, underwriting appetite, claims strategy, reinsurance purchasing and overall business planning. The work must balance commercial objectives with strong governance and regulatory expectations ensuring decisions are robust, transparent and aligned to policyholder outcomes.
To do this effectively, actuaries must combine strong technical capability with an understanding of insurance products, customer behaviour and the wider regulatory environment. A detailed grasp of probability, statistics, modelling and financial drivers is essential, as is familiarity with requirements such as Solvency UK capital expectations, PRA supervisory standards, and financial reporting frameworks like IFRS 17.
Actuaries typically collaborate closely with underwriting, claims, finance, risk, compliance, and senior leadership teams. By analysing experience data, setting assumptions and stress-testing scenarios, they help ensure the business remains resilient; protecting customers, supporting sustainable growth and strengthening confidence in the insurer’s ability to pay claims.
In short, actuaries are the insurance industry’s risk and financial insight specialists; they help organisations make better decisions by quantifying uncertainty, strengthening governance, and ensuring long-term commitments to customers are affordable and deliverable.
There is no single mandatory qualification required to begin an actuarial career, but most actuaries in the UK insurance market start with a strong academic background, typically including Alevels (often Mathematics) and a degree in a numerate subject such as mathematics, statistics, economics, engineering or a physical science. Employers will usually look for evidence of analytical ability, numerical confidence, problemsolving skills and the ability to communicate complex ideas clearly.
The primary professional qualification route for actuaries in the UK is through the Institute and Faculty of Actuaries (IFoA) however many employers expect or support progress towards CII qualifications relevant to the business area/s an Actuary is supporting, typically at RQF Level 3 or above. So, if you are looking to increase your options and develop your career, achieving a relevant qualification will put you in a competitive position.
Many Actuaries will have achieved or be working towards at least a level 3 qualification. The main examining bodies offering qualifications are:
Before choosing which qualifications to take, we recommend you do some research into the methods of assessment and the time commitment involved. Actuarial exams require consistent study over several years, and different employers may offer different levels of study leave, tuition support and exam pathways. Each individual will have their own preferences, so deciding on a route that best suits your strengths is an important step.
It is also worth considering the qualification preferences of the firms you are hoping to work for; find out if they support a particular route or expect progress against defined exam milestones.
While actuaries typically qualify via the IFoA, CII study can be a valuable way to build broader insurance knowledge, especially around insurance principles, regulation and products, supporting actuaries who want stronger commercial context or who work closely with underwriting, distribution or compliance teams.
At BTS, we support the CII route so the information in this profile focuses on some of the main qualifications offered by the CII. Below you will find an overview of the Certificate in Insurance, CII Diploma in Insurance and the CII Advanced Diploma in Insurance, along with links to detailed information on each of the exams that make up the qualifications.
The CII Certificate in Insurance is an RQF Level 3 qualification made up of 3 modules. There are 2 routes to take depending on the area of the insurance industry you want to specialise in: General Insurance or the London Market.
For the General Insurance route, IF1 (Insurance Legal and Regulatory) is a mandatory module and although the modules can be taken in any order, we recommend starting with this as it covers the essential principles of insurance and provides a solid grounding for the other units. We would then suggest moving on to I11 (Introduction to Risk Management) as this gives a comprehensive introduction to the world of risk management and looks at the tools used to identify, classify, value and manage risk, before finishing with a module relevant to the business area you’ll be supporting most such as IF3 (Insurance Underwriting Process) or IF4 (Insurance Claims Handling Process) for example to hone your knowledge of how these business areas function.
For the London market route, LM1 (London Market Insurance Essentials) and LM2 (London Market Insurance Principles and Practices) are both mandatory modules and as with the General Insurance route the modules can be taken in any order but we recommend starting with the two mandatory ones to gain the foundation knowledge of the London Market and it’s processes and procedures before again moving on a module relevant to the business area you’ll be supporting most to hone your knowledge of how these business areas function. Completing LM1, LM2 and any other module will result in the achievement of the Certificate in Insurance rather than the Certificate in London Market Insurance unless your final module is LM3 (London Market Underwriting Principles), the London Market equivalent of IF3.
The CII Diploma in Insurance is an RQF Level 4 qualification designed to build advanced technical knowledge across key areas of general insurance. It is made up of a mix of core and optional units, allowing you to tailor your learning to your career goals. While there’s no fixed order in which you must take the exams, some units naturally complement each other and may be better tackled together.
Although it is often referred to as the toughest Diploma level module, we strongly suggest starting with M05 (Insurance Law), as it lays a strong legal foundation that supports many of the other units and revisits the core principles of insurance from the certificate level modules in greater detail. M05 is one of the mandatory modules, as is M92 (Business and Finance) so this may be a good choice to do next as it focuses on how insurance businesses are managed and details the governance and accounting principles associated with financial success.
After completing both mandatory modules, we recommend continuing the risk management theme from your Cert CII with M67 (Fundamentals of Risk Management) to further enhance your technical knowledge in this area.
To finish your Diploma, we suggest choosing one of the optional modules that fits with the role of the business area you’ll be supporting most in order to better understand the processes and practices followed. This could be M80 (Underwriting Practice) or M85 (Claims Practice) for example.
To complete the Diploma, you’ll need to gain 120 CII credits, with at least 90 credits at Diploma level or above. The credits awarded for each Diploma level module vary from 20-30 so it’s important when choosing your optional modules that you ensure they give you enough credits to fully achieve your Diploma.
The CII Advanced Diploma in Insurance is a level 6 qualification. It is becoming increasingly common for insurance professionals to pursue level 6 qualifications and even achieve Chartered status.
To complete the Advanced Diploma, candidates must already hold the CII Diploma in Insurance. The Advanced Diploma is made up of a selection of modules totalling 290 credits (with at least 120 coming from having completed your Diploma). As with the Certificate and Diploma level qualifications, the Advanced Diploma also has mandatory modules and again we suggested starting with the one that fits with the role of the business area you support:
The remaining 120 credits can be obtained from the optional modules or other mandatory ones.
As the mandatory modules are focused more on the business area you’ll be supporting, our suggestion here would be to follow 820 (Advanced Claims) with 996 (Strategic Claims Management) if you’re closer to claims or follow 960 (Advanced Underwriting) with 995 (Strategic Underwriting) if your closer to underwriting. Getting back to the risk management theme though, after completing your first two ACII modules, we’d then recommend 992 (Risk Management in Insurance) and 997 (Advanced Risk Financing and Transfer) to elevate your knowledge relevant to your role even further.
To finish off your Advanced Diploma, it would make sense to complete 990 (Insurance Corporate Management) to learn more about how insurance businesses are managed. Alternatively, you may wish to consider one of the other mandatory modules to gain a better understanding of how these areas of the industry support and impact your business area. The CII Qualifications Framework shows the full range of CII units, their level and credit value.
A typical day for an Actuary may include:
Career development for an Actuary often begins in a trainee or actuarial analyst role, where individuals learn the fundamentals of insurance risk, data analysis and modelling while studying towards professional qualifications. At this stage, they build technical foundations in statistics, financial mathematics and modelling approaches, while gaining practical exposure to how an insurer operates.
As knowledge and confidence develop, actuaries typically progress to taking ownership of workstreams such as pricing reviews for a product line, reserving analyses for a portfolio, or components of capital modelling and stress testing. They develop stronger judgement in setting assumptions, explaining movements and influencing business decisions with evidence-based recommendations.
With further experience, actuaries can move into specialist or leadership roles. Some focus deeply in a technical area (e.g., pricing, reserving, capital, IFRS 17, reinsurance or model risk), while others broaden into management, risk leadership or strategic roles that influence business direction. Senior actuaries often mentor junior colleagues, lead peer reviews, strengthen governance frameworks and act as key advisors to executives.
The actuarial career path is varied and rewarding, offering strong opportunities to develop analytical expertise, commercial judgement and leadership capability across the wider insurance and financial services sector.
Actuaries are employed by UK insurers, reinsurers, Lloyd’s and London Market firms, consultancies, brokerages, and other financial services organisations where risk and long-term financial commitments need to be quantified and managed.
