I know plenty
of people that have DIYed an unvented
cylinder.

You have to be BBA approved to fit an unvented cylinder.

Not in this country. What is BBA?

Stop trying to be know-it-all. In the UK you need to be BBA approved to fit
a pressurised cylinder.


There's no need to be rude.

- I don't believe that Chris is in the UK....

- In the UK, the position appears to be as follows:

From the Building Regulations, 2000

Hot water storage

********************
G3. A hot water storage system that has a hot water storage
vessel which does not incorporate a vent pipe to the atmosphere shall
be installed by a person competent to do so, and there shall be
precautions -


(a) to prevent the temperature of stored water at any time exceeding
100°C; and

(b) to ensure that the hot water discharged from safety devices is
safely conveyed to where it is visible but will not cause danger to
persons in or about the building.

********************

Note that there is a requirement for competence without it being
defined, just as in the Gas Safety (Installation and Use) Regulations.






From the Approved Document to Part G:

The unit or package should be installed by a competent person, i.e.
one holding a current Registered Operative Identity Card for the
installation of unvented domestic hot water storage systems issued by

a) the Construction Industry Training Board, or

b) the Institute of Plumbing, or

c) the Association of Installers of Unvented Hot Water Systems
(Scotland and Northern Ireland), or

d) individuals who are designated Registered Operatives and who are
employed by companies included on the list of approved installers
published by the BBA up to the 31st Dec 1991, or

e) an equivalent body




Notably, this says "should" and not "shall".

The IoP maintains one of the Competent Persons schemes allowing self
certification as opposed to a Building Notice.


The Statutory Instrument does not appear to preclude submitting a
building notice
