Are you an experienced HVAC Service Engineer looking to take the next step in your career?

Do you thrive on solving complex faults, mentoring others, and taking pride in high-quality service delivery?

We're looking for a Senior Service Engineer / Team Lead to join our growing team and play a key role in maintaining and developing our service operations across the UK.

The Role

As a Senior Service Engineer, you'll be the go-to technical lead for the service team - working both hands‑on and in a leadership capacity. You'll take responsibility for the day-to-day service delivery, mentor and support junior engineers, and ensure that our clients receive a reliable, professional, and technically excellent service every time.

Key responsibilities

• Leading by example on service and maintenance visits across commercial and light industrial HVAC systems (VRV/VRF, splits, heat pumps, ventilation systems).
• Acting as the senior point of contact for complex fault finding, system diagnostics, and commissioning support.
• Supporting the service manager with day‑to‑day team coordination, workload planning, and quality control.
• Providing guidance and mentoring to less experienced engineers – helping to build a high‑performing team.
• Completing service reports, technical feedback, and communicating with clients professionally and clearly.
• Contributing to process improvements and service delivery standards as the business continues to grow.

What We're Looking For

We’re seeking a confident, technically skilled engineer who brings both deep experience and a proactive mindset. You should be as comfortable leading a team as you are working independently on the tools.

Essential skills & experience

• Minimum 5 years' experience in air conditioning service and maintenance.
• Strong knowledge of VRV/VRF, splits, and associated control systems.
• F‑Gas Category 1 qualified.
• Excellent fault‑finding, commissioning and diagnostic skills.
• Full UK driving licence.

Desirable (but not essential)

• Previous team leadership or mentoring experience.
• Manufacturer training (e.g. Daikin, Mitsubishi, Fujitsu).

Pay: £45,000.00‑£65,000.00 per year
