Job Summary

PrimeFix is looking for a skilled and motivated Plumber / Leak Detection Engineer to join our growing team.

In this role, you’ll be responsible for locating, diagnosing, and repairing water leaks in residential properties using modern leak detection equipment and proven plumbing techniques. You’ll work independently and as part of a professional team, delivering high-quality workmanship and outstanding customer service.

This is an excellent opportunity to join a company that values reliability, technical expertise, and continuous development. If you’re passionate about solving complex plumbing issues and take pride in your work, we’d love to hear from you.

Responsibilities

Carry out water leak detection surveys using acoustic listening devices, thermal imaging cameras, tracer gas, moisture meters, and pressure testing equipment
Accurately diagnose and locate hidden leaks in domestic and commercial plumbing, heating, and water distribution systems
Carry out repairs to pipework, valves, fittings, sanitary ware, and heating systems to a high standard
Travel to job sites across London and the surrounding areas using the company-provided van
Communicate findings and recommended repairs clearly and professionally to customers on site
Complete digital job reports for each visit, including photographs and supporting documentation
Plan and manage your own workload to complete jobs efficiently and to a high standard
Follow health and safety procedures at all times, both on-site and while operating equipment
Maintain and look after the company van and specialist equipment provided

Experience

Proven experience in water leak detection, plumbing, or both (commercial or residential settings)
Hands-on experience using specialist leak detection equipment — acoustic listening devices, thermal imaging cameras, tracer gas, moisture meters, and pressure testing equipment
Practical experience diagnosing and repairing pipework, valves, fittings, sanitary ware, and heating systems
Experience working independently and managing your own job schedule across multiple sites
Experience completing digital job reports or using job management apps (photos, notes, documentation)
Previous self-employed or subcontractor experience is an advantage, but not essential
Why join PrimeFix Group

Join a growing network of experienced leak detection engineers working across London and the surrounding areas. We provide the van, the specialist equipment, and a steady stream of work — you bring the skill and independence to get the job done right. If you’re a proactive problem-solver who takes pride in accurate diagnostics and quality repairs, we’d like to hear from you.

Pay: £49.50-£90.00 per hour
