JLL is seeking a skilled Mobile Gas Engineer to service a portfolio of commercial properties in London. You will perform reactive maintenance and planned preventative maintenance on gas systems, diagnose faults efficiently, and ensure safety and compliance across sites.
You will install and commission gas systems, conduct safety checks, and keep accurate records. A company vehicle, fuel card, and modern tools are provided to support professional and reliable service.
Our people at JLL are shaping the future of real estate for a better world by combining world class services, advisory and technology for our clients. We are committed to hiring the best, most talented people and empowering them to thrive, grow meaningful careers and to find a place where they belong. Whether you’ve got deep experience in commercial real estate, skilled trades or technology, or you’re looking to apply your relevant experience to a new industry, join our team as we help shape a brighter way forward.
You're Gas Safe qualified with commercial tickets and real experience. But you're working for outfits that cut corners, chase the cheapest price, and leave you to carry the can when something goes wrong.
What if you could use those skills somewhere that actually does things properly? Where compliance isn't a suggestion, backup isn't a myth, and your van doesn't break down every other month because we’ll sort it next week.
We're looking for mobile gas engineers who want more than just reactive callouts and broken promises. At JLL, you get the stability, equipment, support, and career options that smaller operations simply cannot provide.
100% adherence to Gas Safety Regulations isn't optional at JLL — it's non‑negotiable. You'll never be pressured to cut corners or sign off work that isn't right. Your Gas Safe registration matters to us, not just for legal cover but because we actually care about doing things properly.
Company vehicle that's actually serviced, fuel card that doesn't get declined, and proper tools provided from day one. You're a gas engineer, not a mobile tool library funding someone else's business.
Diverse portfolio across London means proper systems — modern condensing boilers, complex heating controls, commercial plant rooms, and installations that require genuine technical skill. Not the same domestic boiler swap on repeat.
Competitive salary with transparent structure, not day rates that vanish when contracts dry up. The security of a FTSE 250 company with blue‑chip clients and long‑term accounts. You get paid on time, every time.
Regional engineering teams, technical support, and site managers who actually answer calls. You're mobile but supported — when you need help, you get it. When something's unsafe, you can stop work without career consequences.
Clear pathways to senior engineer, supervisor, and contracts manager roles. We promote from within because developing good people makes more sense than constantly recruiting replacements who don't know the sites.
Ongoing professional development, additional Gas Safe qualifications funded, and exposure to modern commercial systems and FM best practices. Keep your skills current and your career moving forward.
You'll cover a portfolio of commercial properties across London, handling reactive maintenance callouts and planned preventative maintenance on gas heating systems, boilers, and appliances.
Your day involves efficient fault diagnosis and repair to minimize client downtime, installation and commissioning of commercial gas systems, and conducting gas safety checks with accurate record‑keeping.
You'll carry out PPM in accordance with manufacturer specifications and statutory requirements, complete risk assessments and method statements properly, and maintain your company vehicle and equipment to high standards.
This means working independently across multiple sites, making professional decisions, and representing JLL's engineering excellence to building occupants and clients. You'll provide excellent customer service, use mobile technology for job management, and participate in on‑call rota as required.
Real commercial gas engineering on quality properties where your work matters and your expertise is recognized.
We're looking for gas engineers who want to work properly, not just quickly. Someone who takes pride in quality installations, understands that compliance protects everyone, and sees this as a career move rather than just another mobile contract.
You’ll join a professional engineering community within one of the world's leading real estate and facilities management companies. That means proper systems, quality clients, modern equipment, and genuine support when you need it.
At JLL, your Gas Safe qualifications and commercial experience are valued, not just exploited. You'll work on landmark properties, collaborate with skilled colleagues, and have access to training and career progression that smaller firms cannot offer.
This is your chance to use your gas engineering skills somewhere that does things right — where mobile engineer is a starting point, not a life sentence driving between breakdowns.
