As a key member of the Detention Engagement Team based at Colnbrook and Harmondsworth Immigration Removal Centres (IRC), you will work directly with individuals being held securely while their case is progressed. Your role involves face-to-face engagement with them about their return, ensuring they understand the process and steps required to bring their case to a conclusion. You will also be responsible for monitoring and supporting their welfare, raising concerns promptly, ensuring access to information and services, and contributing to a safe, professional and respectful environment within the centre.
In this role you’ll be making a genuine difference, supporting vulnerable people at a difficult point in their lives while helping to maintain safe, lawful and effective immigration controls for the UK.
Serving as a Detention Engagement Officer means that each working brings new and different experiences.
Your role is multifaceted and will involve face-to-face engagement with detained residents, supporting them to understand their case and ensuring they receive clear information at the right time. You will provide steady, practical guidance that helps them move through the immigration process in a safe, lawful and timely way.
As a key point of contact, you’ll help maintain strong links between residents, their caseworking teams, on-site healthcare and other service providers, making sure communication is consistent, accurate and dependable.
Because much of your work is people-facing and often sensitive, you will need to be a calm, confident communicator who can build trust quickly and maintain professionalism and integrity, even in challenging situations.
The role and the environment can be demanding so you’ll need to bring resilience and a confident approach. You’ll operate within a secure facility with residents confined to designated areas. You’ll encounter emotionally charged moments and challenging behaviour, but you won’t face them alone. With comprehensive training and a strong, supportive team around you, you’ll quickly build the confidence and assurance needed to handle complex situations professionally and safely. You also need to be aware that the role can be physically demanding as you’ll spend much of your day on the go.
These roles are based at Colnbrook and Harmondsworth IRCs, both of which are located next to Heathrow Airport. The Centres are purpose-built facilities with capacity between them to house around 900 adult men who are either foreign national criminals, immigration offenders, illegal small boats arrivals or failed asylum seekers. Two of the seven residential units at Harmondsworth IRC are built to Category B (high security) prison specifications. The Centres are located next to each other, and you will be expected to work at both. Whilst both have lifts, usage cannot be guaranteed so you will need to be comfortable using stairs. Both Centres can be reached by bus from nearby train stations. Car parking for staff is limited. The successful candidate must be available to attend the centre for all scheduled shifts.
Key Responsibilities
- Conduct face-to-face engagement with residents: Manage interactions with a portfolio of residents, delivering inductions, serving official paperwork and providing clear explanations to help them understand the next steps in their case, which include returning to their country of origin and the consequences of non-compliance.
- Support vulnerable people: Work collaboratively with all stakeholders to support and signpost vulnerable people.
- Be the onsite link: Work collaboratively with caseworking teams, healthcare providers and the IRC supplier to resolve issues relating to case progression quickly and professionally.
- Undertake information gathering and record keeping: You will need to take an unbiased and methodical approach to information gathering. Daily interactions and case updates should be logged promptly and accurately, providing a clear audit trail on Home Office IT systems to support case progression and the smooth running of the team.
- Work safely and professionally: Act professionally and with integrity, following security, safeguarding and confidentiality requirements at all times.
- General administrative duties: This includes inbox management and answering phone calls.

You will need to undertake your role entirely within the IRC; working from home is not possible.
