All our projects come with a gas and electrical certificate as standard . Strict rules and regulations to these standards are a must for ourselves and to adhere to the law . Please note as an example a gas locker has to have adequate ventilation gas dispersal incase of a leak. Withstand 30 minutes of fire and also have no sources of ignition ie 12v ,240v .
The number of times we see (professional conversions) and a gas locker will have 240v consumer unit ! 240v hookup point! A 12v water pump in the compartment . And then be lined out with plywood. These will not be legal and definitely not safe for the user .
Please do not spend good money on something that is not safe.
Not only does the qualified person got to be gas safe he also has to be LPG and commercial catering qualified .
