Recruitment agencies need a reliable candidate pipeline to keep vacancies moving.
But sourcing, CV searching, pre-screening, cold candidate outreach, database work, and recruitment administration can quickly consume recruiter time.
Mars Outsourcing Ltd provides specialist Recruitment Process Outsourcing (RPO) and recruitment outsourcing support for recruitment agencies and employers across the UK.
We work as an extension of your recruitment operation, supporting the delivery work behind your vacancies while your recruiters remain focused on clients, candidates, interviews, and placements.
Recruitment experience since 2016.
Outsource the delivery work. Keep control of the placement.
Built for Recruitment Agencies That Need More Delivery Capacity
Running a recruitment desk means balancing several priorities at once.
You need to win and manage clients, understand vacancies, source candidates, speak with professionals, arrange interviews, follow up with candidates, and close placements.
When sourcing and administrative work takes too much of your day, delivery can slow down.
Our recruitment outsourcing model is designed to give agencies additional operational capacity across the parts of recruitment that can be delegated.
Use Outsourced Support When You Need To:
Work on more vacancies without expanding internal headcount
Increase candidate sourcing capacity
Search multiple candidate databases
Reduce repetitive recruitment tasks
Re-engage candidates already in your database
Support urgent or high-volume vacancies
Research difficult-to-find talent
Build candidate pipelines for future requirements
Give recruiters more time for client and candidate conversations
Recruitment Process Outsourcing for Recruitment Agencies
Our RPO support can be structured around the recruitment activities you need help with.
CV Sourcing
Receive candidate CVs and profiles identified according to your agreed recruitment criteria.
We can search relevant recruitment databases, job boards, professional platforms, and other permitted sourcing channels to identify candidates matching the vacancy.
Best for: Recruitment desks that need consistent candidate delivery.
Candidate Sourcing & Outreach
Sourcing a CV is only the beginning.
Our pre-screening support can help establish whether a candidate meets agreed criteria and whether they are interested and available before progressing them to your recruitment team.
This can help reduce time spent chasing candidates who are unavailable, unsuitable, or no longer interested in moving roles.
Best for: Agencies dealing with high candidate volumes or urgent vacancies.
Cold Candidate Outreach
A strong candidate database only creates value when relevant candidates are contacted and engaged.
Our outreach support can help contact suitable professionals through agreed channels, confirm interest, and identify candidates who may be open to relevant opportunities.
We can also help re-engage older candidates already sitting within your recruitment database.
Your old database may contain future placements.
LinkedIn Sourcing
Most sourcing stops at LinkedIn. We don’t.
We search LinkedIn Recruiter with 20+ filters to pull accurate, role-matched profiles — prioritising open-to-work candidates for faster placements. Then we cross-check contact details through multiple lead tools, so outreach starts with a real email, not a guess
Talent Mapping
We can research target companies, candidate profiles, job titles, locations, skills, and experience to create a structured view of the available talent market.
Best for: Specialist recruitment, difficult vacancies, executive search, and future hiring pipelines.
Recruitment Administration Support
Recruiters should spend their time where their expertise creates the greatest value.
Our recruitment administration support can help with defined operational tasks such as:
- Lead Generation
- Candidate database management
- CV formatting
- Recruitment research
- Data cleansing
- Data migration
- Candidate records
- Recruitment reporting
This gives your consultants additional time without requiring another permanent internal employee.
Recruitment Support Without the Traditional Agency Percentage
Traditional recruitment agencies may charge around 10–12% of a candidate’s salary for recruitment services.
Mars Outsourcing offers an alternative model for businesses that want dedicated recruitment support without paying a percentage of the candidate’s annual salary.
Our employer recruitment support is available on a fixed-cost basis agreed 50% of the operational cost paid upfront, with services starting from £500 for junior roles in major UK locations.
Instead of paying a percentage of salary, you can access practical recruitment support for a defined cost.
Our Employer Recruitment Support Can Help Businesses:
Source relevant candidates from major UK job boards
Search professional recruitment platforms and candidate databases
Confirm candidate interest and availability before progressing them
Reduce the workload on internal hiring teams
Support junior and mid-level recruitment requirements
Access recruitment support without a percentage-based placement fee
Manage individual vacancies or ongoing recruitment requirements
Whether you have one vacancy or an ongoing hiring requirement, our fixed-cost model can be structured around your recruitment needs.
Less focus on percentage fees. More focus on practical recruitment delivery.

UK Recruitment Outsourcing
Recruitment Support for the UK Market
Mars Outsourcing provides online recruitment outsourcing support for UK recruitment agencies, employers, staffing companies, and hiring teams.
Our support can be structured around UK-focused vacancies, candidate sourcing, recruitment research, pre-screening, outreach, and recruitment administration.
Whether you recruit nationally or specialise in a particular UK sector, location, or candidate market, our workflow can be adapted to your requirements.
Premium Recruitment Sourcing Channels
Effective recruitment sourcing requires more than searching one platform.
We’ve invested in premium CV databases and LinkedIn Recruiter (RPS+) access to give our sourcing team access to broader research opportunities.
Depending on the project and permitted access, sourcing can involve platforms such as LinkedIn Recruiter (RPS+), CV databases, Reed, CV-library, Jobsite, Totaljobs, major job boards, professional networks, and targeted candidate research.
This multi-source approach allows us to search beyond a single candidate platform and build more targeted recruitment pipelines.
The goal isn’t more CVs. It’s more relevant CVs.
Candidate Relevancy Benchmark
Recruitment sourcing should not be measured by the number of CVs delivered alone.
Our sourcing process focuses on matching candidates against the specific requirements of each vacancy, including role, skills, experience, location, and availability.
Mars Outsourcing typically reports 80–98% candidate relevancy, depending on the role, recruitment niche, market availability, and complexity of the search.
This range reflects the reality that candidate markets differ between vacancies. Highly specialised or senior roles may naturally produce a smaller pool than high-volume junior positions.
Our priority is relevant candidates — not simply a larger CV count.
Recruitment Experience Since 2016
Our team brings recruitment and outsourcing experience dating back to 2016.
That experience has involved the practical side of recruitment delivery, including candidate sourcing, research, screening, outreach, talent identification, and recruitment operations.
We understand that recruitment agencies are measured not simply by how many CVs they receive, but by the quality and relevance of the candidates progressing through their pipeline.
That’s why our approach focuses on defined requirements, structured sourcing, candidate relevance, and clear delivery workflows.

From Recruitment Workload to Additional Delivery Capacity
The Challenge
A recruitment agency was managing multiple vacancies while its internal recruiters were spending significant time on candidate sourcing, database research, and early-stage candidate engagement.
The additional workload reduced the time available for client communication, interviews, candidate management, and placements.
The Approach
Mars Outsourcing supported the agency’s recruitment workflow by handling agreed delivery tasks such as:
- Candidate sourcing
- CV Formatting
- Candidate pre-screening
- Candidate outreach
- Talent pipeline development
The process was built around the agency’s vacancy requirements and existing recruitment workflow.
The Result
Use verified metrics such as:
- Number of vacancies supported
- Candidates sourced
- Candidates contacted
- Candidates screened
- Interviews generated
- Time saved
- Placements generated
- Cost per supported vacancy
Example:
During 2 months, Mars Outsourcing supported 25 vacancies, sourced 150 candidates, and generated 45 qualified candidate submissions.
Key Takeaway
Outsourcing defined recruitment delivery tasks can give agencies additional capacity while allowing their internal recruiters to focus on the activities that require direct client and candidate interaction.

Frequently Asked Questions About Recruitment Outsourcing
What is recruitment outsourcing?
Recruitment outsourcing involves delegating selected recruitment activities to an external specialist while the agency or employer retains control over its wider recruitment strategy.
This can include candidate sourcing, research, screening, outreach, talent mapping, and recruitment administration.
How does Mars Outsourcing work with recruitment agencies?
We work as an extension of your recruitment delivery function.
You provide the vacancy requirements and candidate criteria. We handle the agreed sourcing, research, screening, or outreach activities and deliver relevant candidate information back to your team.
Your recruiters retain control of the client relationship, interviews, candidate management, and placement.
What happens if we're not happy with the candidates you source?
We review your feedback and refine the search according to the agreed criteria.
Our process is built around your specific requirements, with the objective of improving candidate accuracy and relevance rather than simply increasing CV volume.
How quickly can you start sourcing candidates?
Once the vacancy requirements and workflow are agreed, sourcing can begin according to the agreed project timeline.
Delivery speed depends on role complexity, market availability, location, seniority, and search requirements.
Which job boards and platforms do you use?
Depending on the project and permitted access, sourcing may include LinkedIn Recruiter (RPS+), Reed, CV-Library, Totaljobs, Jobsite, recruitment databases, professional networks, and targeted online research.
The sourcing mix depends on the vacancy and candidate market.
How do you make sure sourced CVs match our criteria?
We match searches to your specific criteria and use AI-powered tools to improve accuracy. Every sourced CV is reviewed against your requirements before delivery.
How many CVs will we receive per vacancy?
There is no universal number because candidate availability varies by role, location, seniority, skills, and market conditions.
Our focus is on candidate relevance rather than an arbitrary CV volume target.
What's your candidate accuracy or relevancy rate?
Mars Outsourcing typically delivers **80–98% candidate relevancy**, depending on the role, niche, market availability, and search requirements. We use AI-powered recruitment tools alongside human expertise to improve search accuracy, identify better-fit candidates, and provide clients with more relevant profiles—helping reduce wasted time and improve hiring outcomes.
This is a benchmark, not a universal guarantee, as every recruitment market is different.
Do you confirm candidate availability before sending their CV?
