Gas Safe Registered
Gas Safe is the official regulatory body for gas safety in the UK. All gas engineers must be registered with the Gas Safe Register to work legally on gas appliances.
It is essential to ensure that any engineer working on your gas appliances is Gas Safe registered to ensure your safety from potential gas leaks and other gas-related dangers. Gas Safe registered engineers are trained and qualified to work on gas appliances and are legally accountable for their work.

OFTEC registered
OFTEC (Oil Firing Technical Association) is a UK-based trade association that provides certification and support to oil heating engineers. They are an independent, not-for-profit organisation that works to ensure safe, efficient and environmentally responsible oil firing.
Ensuring that your engineer is OFTEC registered when working on your oil appliance at home or business is essential because your engineer is fully qualified and experienced to work with oil heating systems.
This means they will be able to carry out the job safely and to the highest standards. OFTEC also requires their registered engineers to follow strict codes of conduct, so you can be sure they will be respectful and considerate when in your home.
