Working on gas boilers and gas appliances is not DIY... Taking off the case to
an appliance means you have to undertake statutory checks to ensure the

three years and have seen some absolutely leathial fiddling by the don't want
to pay for it idiots. Its not funny when you turn up with the police to find
someone dead. Leave all gas work to fully professionals

The essential qualification is competence. Amateurs do not have a
monopoly on incompetence or carelessness.
