Salary: £65,000 - £80,000 per annum
Schedule: Monday–Friday, 9am start (occasional weekend work available)
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 resolve issues quickly and with minimal disruption.
Due to continued growth, we are looking for someone to join our team as a Leak Detection Technician, ideally based around the M25 — particularly Guildford 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.
Likewise, if you are an experienced plumber this could be a new challenge for 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
Ideally you will 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.
Alternatively, you will be an experienced and confident plumber who is looking to start a fresh role.
Full training in leak detection will be provided.
You will be finding, accessing and fixing water leaks on heating systems, hot and cold feeds, waste and mains pipework.
You will be using modern, non‑invasive equipment including thermal imaging, tracer gas, acoustic listening devices and moisture meters. You will also be supporting customers by accessing and fixing water leaks 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).
