GAS ENGINEER – (Field Service Engineer)
Job description
At Baxi, our Gas Engineers are the face of our brand, delivering expert service, maintenance, and repair support to customers across their region. A typical day involves diagnosing and resolving technical issues on domestic heating systems, commissioning new installations, and ensuring appliances are operating safely and efficiently. You’ll work independently in the field, building trusted relationships with customers while upholding the highest standards of safety, quality, and customer care — playing a vital role in supporting reliable heating solutions and the UK’s transition to lower-carbon energy.
Location: Swindon / Reading / Bath
Salary: £44,984.22 + Monthly Bonus
Company Vehicle: Company Van + Fuel Card
Pension: Contributory pension scheme
Working Pattern: You will average 41.5 hours per week over the year working annualised hours (less in summer more in winter) but your pay will not change! This includes some weekend, evening and bank holiday work.
The Person:
We’re looking for a customer-focused, technically skilled Gas Engineer who takes pride in delivering a first-time fix and outstanding service. You’ll be a self-motivated problem solver, confident working independently in the field while representing Baxi with professionalism and integrity.
You’ll combine strong diagnostic ability with excellent communication skills, building trust with customers and colleagues alike. Safety-conscious, organised, and resilient, you thrive in a hands-on role where no two days are the same, and you’re committed to continuous learning as heating technology evolves towards more sustainable, low-carbon solutions.
The Role:
As a Gas Engineer at Baxi, you will be responsible for delivering high-quality service, maintenance, and repair support across domestic and commercial heating products within your designated region. Working remotely in the field, you will diagnose faults, complete repairs, commission new appliances, and carry out annual servicing in line with industry standards and safety regulations.
You’ll manage your own daily schedule, provide technical advice to customers and installers, and ensure every job is completed to the highest standard of safety, efficiency, and customer satisfaction — playing a key role in supporting reliable heating solutions and our journey towards lower-carbon technologies.
This role operates on an annualised hours basis, meaning you’ll average 41.5 hours per week across the year — typically working fewer hours during the summer months and more during our peak winter period. Your salary remains consistent throughout the year, providing income stability while reflecting the seasonal nature of our industry. The role will include rotated Saturdays, and bank holiday working as part of this structure.

Requirements:
