As a Plumber / Gas Safe Engineer in our Justice and Immigration Facilities Management team, you’ll play a key role in maintaining gas systems and plumbing infrastructure within a secure environment. Your work will help ensure essential services remain safe, compliant, and reliable for everyone on site.

You’ll be entrusted to:

  • Diagnose faults and complete defect rectification on plant and equipment
  • Install new plant, systems, and equipment as required
  • Support colleagues across the maintenance team with wider site activities
  • Maintain accurate schedules, records, and reports on work completed
  • Investigate equipment performance issues and provide recommendations for improvement

 

Does this sound like you?

You’ll be a great fit for this role if you have…

  • A recognised trade apprenticeship or equivalent plumbing qualification (City and Guilds or NVQ)
  • Gas Safe registration with relevant commercial and domestic gas qualifications
  • Experience working with both commercial and domestic systems
  • Strong problem-solving skills with the ability to work independently and prioritise workload
  • Good communication skills and a proactive approach to teamwork and continuous improvement

This includes spent and unspent convictions, cautions, and any relevant information held by local police, in accordance with the Rehabilitation of Offenders Act and safeguarding requirements. You will also complete an Occupational Health Questionnaire to allow us to provide any support needed for you to succeed in the role.
