    If it's under 15 litres then competent person can. (Edit - sorry, this is incorrect wc1)

    Are you asking if you can work on the cylinder itself or the hot water system after the cylinder?

    Just had a look around and unfortunately there is a lot of info stating under 15l is ok for non g3 (and some of it is quite recent)
    Lucky I got my g3 ticket...

    Both actually.
    I’ve tried Googleing to find out what I can and can’t touch but it’s vague so wanted to know more.

    Need g3 updated the regs in 2010 ish g3 covers all hot water systems now only difference is you don’t need to have under 15 l signed off by building control or gas safe eg registered

    Was discussing this with a colleague yesterday and looking at NVQ L3 textbook (C&G 6189) "Unvented undersink heaters...Because they are less than 15 litres of storage, they are not subject to the stringent regulations that surround the installation of larger... " - published in 2017. Pretty misleading! smh
