Certificates and registrations
JFES registrations, assessments and training.










Gas registration, electrical qualifications and oil training
Gas Safe registered
Reg. no. 600276, for John Francis Engineering Ltd. Ask to see the current ID card and scope of the engineer attending your job.
Gas Safe Register is the official list of engineers legally allowed to work on gas appliances in the UK. Every registered engineer carries a Gas Safe ID card showing what work they're qualified to do.
Depending on gas appliances and gas supply specifications, we can normally carry out gas-based operations in commercial premises — call to check.
OFTEC trained
Did the OFTEC training required for England & Wales installations, but let the Trade Association registration lapse since it isn’t required in Scotland. Still follows OFTEC installation rules on every oil-fired job — covers oil-fired boilers, tanks and heating systems.
