Common questions
What qualifications do I need to work on gas?
You must be on the Gas Safe Register, and the register records exactly which categories of work you are qualified for - domestic boilers, commercial catering, LPG and so on are separate. If your ACS certificates have lapsed we would rather you told us at the interview than after.
Do you take apprentices?
Yes. Apprentices work alongside a qualified engineer rather than being sent out alone, and college time is part of the week rather than something to fit around the job.
What is the working pattern?
Monday to Friday, 8am to 5pm, with a Saturday rota and an on-call rota for emergency work. Most of the week is planned in advance rather than dispatched on the day.
Is a van and tools provided?
Yes - van, tools and test equipment, with calibration handled by the office rather than being your problem.
Do you pay for training and ACS renewals?
Yes. Keeping current is a cost of doing this properly, not something to push onto the person doing the work.
How do I apply if there is no vacancy listed?
Send a CV to the office anyway. Good engineers are worth making room for, and vacancies are not always advertised before they are filled.
