What to Look for in an Executive Assistant Recruitment Agency

The best EA recruitment agencies are distinguished by their expertise across five critical areas.

Selecting the right recruitment agency is pivotal for securing an Executive Assistant who can truly elevate your operations. The ideal agency transcends simply matching CVs; it involves a deep understanding of the unique demands placed upon senior leaders and the specific environments they operate within, such as financial services, family offices, and high-growth professional services firms. When evaluating potential partners, consider these crucial elements that differentiate exceptional agencies from the rest.

1. Experience with Senior Stakeholders

Not all EAs operate at the same level.

Agencies that regularly place assistants for CEOs, Partners, and investment teams are better equipped to assess:

• judgment under pressure  

• communication with senior stakeholders  

• ability to operate without constant direction  

Supporting a founder or investor is fundamentally different from supporting mid-level management.

2. Understanding of Fast-Paced Environments

In investment firms, priorities shift daily.

The best EAs are comfortable operating in:

• high-pressure environments  

• lean, under-resourced teams  

• situations with incomplete or evolving information  

Many agencies assess for experience; fewer assess for adaptability.

3. Network Quality (Not Just Volume)

The strongest agencies rely less on job boards and more on curated networks.

These candidates often have backgrounds in:

• financial services  

• consulting  

• high-growth startups  

A smaller, higher-quality network is often more valuable than a large, inconsistent pipeline.

4. Speed vs Precision

Some agencies optimise for speed. Others optimise for fit.

For junior roles, speed may be acceptable.

For executive-level hires, precision matters more. A mis-hire at this level creates operational drag and requires restarting the process.

How Much Does It Cost to Hire an Executive Assistant in London?

The investment required to hire an exceptional Executive Assistant in London encompasses more than just the individual's salary. It involves recruitment fees, potential bonuses, and benefits, culminating in a significant total first-year cost. Understanding these financial components is crucial for budgeting and assessing the return on investment for this critical hire.  

The dynamic nature of London's market means that compensation packages are highly competitive, particularly for roles supporting senior leaders in sectors like financial services and UHNW family offices.

Typical EA Salary (London)

In London, the salary for an Executive Assistant varies significantly based on experience, responsibilities, and the sector they serve. For a mid-level EA with 3-7 years of experience, salaries typically range from £40,000 to £60,000 per annum.  

However, for senior EAs directly supporting CEOs, partners, or UHNW principals in demanding fields such as investment banking, private equity, or complex family office structures, compensation often escalates to £60,000 – £90,000+, with some highly specialized roles commanding even higher figures. These EAs are expected to handle extensive diary management, complex international travel coordination, and manage significant confidential documentation, justifying the premium.

Recruitment Fees

When engaging a recruitment agency, clients can expect to pay a fee, typically calculated as a percentage of the hired candidate's first-year salary. This fee commonly ranges from 15% to 30%, depending on the agency's specialization, the seniority of the role, and the exclusivity of the search.  

For an EA earning a £70,000 salary, this translates to recruitment fees anywhere from £10,500 to £21,000. These fees cover the agency's recruitment process, candidate sourcing, vetting, and the overall service of finding and presenting suitable individuals. This fee is a significant consideration when budgeting for executive search.

Total First-Year Cost

Factoring in the typical salary, potential bonuses, benefits, and recruitment fees, the total first-year cost of hiring an Executive Assistant in London can be substantial. For an EA with a £70,000 salary, assuming a 20% recruitment fee (£14,000) and an additional 10-15% for bonuses and benefits, the total first-year investment can easily range from £80,000 to over £100,000.  

This figure underscores the importance of selecting the right candidate through a rigorous recruitment process, as a mismatch can result in considerable financial and operational loss. This investment is a strategic one, aimed at enhancing leadership effectiveness and achieving core business objectives.

‍

How Long Does It Take to Hire an EA?

The timeline for hiring an Executive Assistant in London can vary considerably, influenced by the agency's efficiency, the availability of suitable candidates, and the client's interview process.  

Typically, the initial shortlist of candidates can be presented within 1 to 3 weeks, assuming the recruitment agency has a well-developed candidate network and a clear understanding of the role’s requirements. The subsequent interview process, involving multiple rounds and potentially executive assessment services, can add another 2 to 4 weeks.

Furthermore, the candidate's notice period, often ranging from 1 to 3 months for senior roles, must also be factored in. Consequently, the entire hiring process from engagement to the EA's first day can extend from 4 to 12 weeks or even longer, presenting a significant bottleneck for fast-moving firms aiming for swift operational gains.

Why Some Investment Firms Are Rethinking Recruitment Agencies

While recruitment agencies remain the default, many investment firms are reassessing whether the model aligns with how they operate.

Common challenges include:

• Long hiring timelines  

• High upfront costs  

• Risk of misalignment  

• Limited flexibility post-hire  

In lean teams, committing to a full-time hire introduces both cost and rigidity — particularly when workloads fluctuate.

An Alternative: Dedicated Executive Assistant Support

As a result, some firms are shifting toward a different model:

Dedicated executive assistant support

This approach typically involves:

• A full-time, embedded EA  

• Immediate or rapid onboarding  

• No recruitment fees  

• Flexibility to scale or adapt support  

Rather than hiring an individual, firms access a structured support system.

For investment teams, this often translates into:

• faster time to productivity  

• reduced hiring risk  

• greater operational flexibility  

‍

A Modern Alternative: HireHarbour

For firms that want to avoid the delays and rigidity of traditional hiring, providers like HireHarbour offer a different model of executive support.

Rather than acting as a recruitment intermediary, HireHarbour provides managed, embedded executive assistant support designed specifically for high-accountability environments such as private equity, venture capital, and founder-led companies.

This approach removes several common friction points in the hiring process:

• No lengthy recruitment cycles  

• No upfront placement fees  

• Reduced risk of mis-hire  

• Built-in continuity and coverage  

HireHarbour’s model is structured around immediate usability and long-term reliability. Assistants are trained to operate within executive environments, handling calendar management, stakeholder coordination, and operational execution with minimal ramp-up time.

Because support is delivered through a managed system rather than a single individual, firms also benefit from:

• continuity if an assistant is unavailable  

• structured onboarding and knowledge capture  

• the ability to scale support as workload changes  

For investment teams and operators working under time pressure, this model prioritises speed, discretion, and execution consistency over traditional hiring processes.

Which Option Is Right for You?

The choice between engaging a recruitment agency or opting for dedicated executive assistant support hinges on your organization's specific priorities, immediate needs, and long-term strategy.  

Both approaches offer distinct advantages, and understanding which aligns best with your operational context is key to making an effective hiring decision.

Recruitment Agency → Best if:

• You require a permanent, in-house hire who will become an integral part of your company culture.

• You have stable and predictable long-term support needs that justify the investment in a full-time employee.

• You are willing to dedicate time and resources to a structured hiring process, including interviews and reference checks, to ensure the best long-term fit.

• You value the specialized expertise and extensive candidate network that reputable recruitment consultants bring to the table, especially for niche roles like Private PA or support for UHNW principals.

• Your timeline allows for the typical hiring duration, including notice periods for the candidate.

Dedicated EA Support → Best if:

• You need executive assistant support, including administrative support or virtual assistants, quickly and without a lengthy recruitment process.

• Your workload is dynamic, with fluctuating demands that benefit from flexible staffing solutions.

• You wish to minimize upfront recruitment fees and the financial risk associated with a permanent hire, while still securing high-quality administrative staff.

• Your priority is immediate leverage, operational clarity, and enhanced organizational performance without the overhead of a traditional hiring model.

• You are looking for specialized support staff for projects, international travel, or to manage specific aspects of personal lives alongside business objectives.
