The Role

We are recruiting an experienced BMS / Commercial Gas Engineer to operate as a Technical Team Leader (TTL), providing hands‑on expertise alongside the supervision of a multidisciplinary engineering team. This role sits at the heart of our commercial operations and will suit someone with a strong Building Management Systems (BMS) background, commercial gas knowledge, and the confidence to lead engineers across multiple workstreams. You’ll report directly to the Commercial Lead and will be responsible for a team of 5, including Gas Engineers and Wet Fitters, delivering planned and reactive maintenance across commercial sites.

Key Responsibilities

• Technical leadership and day‑to‑day supervision of a commercial engineering team
• Act as the senior technical point of contact for BMS diagnostics, fault‑finding and troubleshooting
• Oversight of commercial gas plant, heating systems, HVAC and associated controls
• Support, develop and performance‑manage engineers on site
• Technical ownership of BMS systems, including Trend / KNX systems, heat metering and billing platforms, integration, monitoring and fault resolution
• Ensure works are delivered safely, compliantly and to agreed standards
• Liaise with clients, management and office teams to maintain service excellence
• Mix of on‑site and office‑based work, depending on operational need

About the Systems

BMS systems control critical building infrastructure including fire alarms, ventilation, heating and energy management. This role requires strong electrical and computer‑based diagnostic capability within a specialist building controls environment.

About You

Essential:

• Strong experience working with BMS systems (Trend, KNX or similar)
• Commercial environment experience (domestic background not suitable)
• Proven supervisory / team‑leading experience across multiple engineers

• Full UK driving licence

Desirable (but not essential): Experience with heat metering and energy billing platforms.

Candidates with strong BMS experience but limited gas exposure will still be considered, provided they bring the right leadership and commercial mindset.
