Defective components and equipment
Defective components cause frustration and cost valuable installation time. If
a component or piece of equipment is found to be defective, do not attempt a
repair as this may invalidate any manufacturer’s warranty. The manufacturer
should first be contacted as they may wish to send a representative to inspect
the component prior to replacement. The supplier should also be contacted
to inform them of the faulty component. In some instances where it is proven
that the component is defective and was not a result of poor installation, the
manufacturer may reimburse the installation company for the time taken to
replace the component.

The procedure for notifying works carried out to the
relevant authority
At all stages of the installation, from design to commissioning, notification of
the installation will need to be given so that the relevant authorities can check
that it complies with the regulations and to ensure that the installation does
not constitute a danger to health. It must be remembered that only operatives
that are registered to do so can install unvented hot water storage systems. The
operative’s registration number must be given on any paperwork submitted to
the local authority.

Under Building Regulations Approved Document G, hot water installations are
INDUSTRY TIP notifiable to the local authority Building Control Office. Building Regulations
approval can be sought from the local authority by submitting a ‘building
Notice should be given to notice’. Plans are not required with this process so it’s quicker and less detailed

comply with the Building Regulations.

Building Regulations Compliance certificates
From 1 April 2005, the Building Regulations have demanded that all
installations must be issued with a Building Regulations Compliance certificate.
This is to ensure that all Building Regulations relevant to the installation have
been followed and complied with.

Commissioning records for cold water systems
Commissioning records, such as benchmark certificates for hot water systems,
should be kept for reference during maintenance and repair, and to ensure that
the system meets the design specification. Typical information that should be
included on the record is as follows:

● the date, time and the name(s) and ID numbers of the commissioning
engineer(s)
● the location of the installation
l the amount of hot water storage and cold water storage (if any)
