Harmuns is a 5‑star rated, specialist non‑invasive water leak detection company based in Windsor, Berkshire.

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.

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).
