Look the law is quite clear there is no problem doing your own gas providing you are competent.
Some diyer's are quite capable of getting to grips with the standards in force and are sufficiently skilled in their work.
Others however are not and never will be (sometimes arrogant and over confident in their abilities), and it is highly irresponsible to encourage them to do their own gas work.
For those of you not gas engineers by trade it is easy to look at this industry and assume its simple and straightforward, read the standards and regulations and perhaps you may decide to re-assess your thoughts.
It is no different to electrical wiring, very easy to wire up a lighting circuit with just the phase and neutral conductors. All appears functional to the user but highly dangerous. Nothing in reserve under fault conditions. Again read the standards - most of which have more to do with redundancy and safety if ever a fault occurs.
So read this lot, get the relevant test gear, and providing the quality of your work is up to scratch you are legally entililed to carry out gas work in your own home.
