Harmuns is a 5‑star rated, specialist non‑invasive water leak detection company based in Windsor, Berkshire. We support customers across London, the Home Counties and the South‑East, delivering high‑quality, accurate leak detection to help homeowners and businesses resolve issues quickly and with minimal disruption.

Due to continued growth, we are looking for a Gas Safe qualified heating engineer to join our team as a Senior Leak Detection Engineer, ideally based around the M25 — particularly Dartford, Epping, Redhill or the very local surrounding areas.

This is an excellent opportunity for an experienced heating engineer who is ready for a new challenge and wants to step away from heavy lifting, repetitive breakdown work, or the physical strain of carrying cylinders. If you have strong technical ability, great communication skills and a problem‑solving mindset, we’d love to hear from you.

We will train, develop and support you to quickly get up to speed with our specialist equipment and processes so you can confidently deliver high‑quality leak detection services and become a valued member of our growing team.

The Role

You must be a Gas Safe qualified heating engineer with at least 5 years’ experience, confident working independently, and able to communicate clearly with customers. You’ll be someone who is reliable, trustworthy and able to bring a calm, methodical approach to the job.

Full training in leak detection will be provided. You will be using modern, non‑invasive equipment including thermal imaging, tracer gas, acoustic listening devices and moisture meters. You will also support customers by carrying out small repairs to exposed areas and producing clear written reports with photos.

This is a full‑time role on an exclusive contractor basis initially, with the opportunity to transition into a permanent PAYE position with enhanced benefits (including pension).
