What constitutes a Certified Design
(reprinted with the consent of Energy Safety)
The Electricity (Safety) Regulations 2010 and the Gas (Safety and Measurement) Regulations 2010 both provide for the use of a certified design to modify the installation standards’ requirements that apply to electrical and gas appliances and fittings, and ensure that essential safety requirements are met.
A design for an electrical or a gas installation, or part installation, is a certified 2 design if:
- It identifies the location or proposed location of the installation or part installation; and
- It identifies the standards (if any) with which the installation or part installation, or proposed installation or part installation, complies or is intended to comply; and
- The person who prepared the design signs and dates it.
A certified design may influence or direct the selection of electrical and gas appliances and fittings, and their installation, or maintenance. Examples of a certified design include an architect's drawing or an engineering design that shows the location of fittings, because these drawings or designs influence the safety of a completed installation. This can be especially useful if the architect or designer knows the intended use of the premises and details that the installing contractor may be unaware of.
