About immersion heater installation services
Replacing a failed element is a short job; the work is usually in draining the cylinder first. The electrical connection falls under Part P in England and Wales, and if the cylinder is unvented, that is a separate qualification again — an unvented cylinder is a pressure vessel and not a job for a general plumber.
