People have been advised against trying to fit certain appliances themselves by an industry body, which could lead to more professionals signing up for gas courses.
The Gas Safe Register suggested only registered engineers should be brought in to install fittings, as there is a lot of scope for error with disastrous consequences.
In comments that may encourage both engineers and amateurs to sign up for gas courses, representative from the organisation Jamie Cooper suggested that it can be "frightening" when things go wrong.
He stated: "When it comes to the safety of your family and home, you can't put a price on that by risking DIY on gas."
In his view, the expenses associated with bringing in a professional are not overly costly, so if people do not know what they are doing, they should hire someone who does.
This month, the Gas Safe Register urged people to carry a portable carbon monoxide alarm with them when they go on holiday, since it claimed the item can save lives.
