Do I need to have someone produce a fire alarm design?

[Great_scot_selfbuild]

I’m trying to make sense of the BR and what I can see of BS5396-6. We’re installing the electrical first fix and have a circuit for fire alarm covering the required areas shown in Approved doc B. What have people done here for their fire alarm design & installation?

The BR guidance seems very straightforward and clear about what we install and where, but then Approved Document B, Volume 1: Dwellings, Section 1, under “Design and installation of systems” also states:

“Fire detection and alarm systems must be properly designed, installed and maintained. A design, installation and commissioning certificate should be provided for fire detection and alarm systems.”

 

Is the mention of fire alarm commissioning certificate (which has a section for ‘designed by’ required for self-build residential homes (I.e. not HMO, not especially large - no single floor over 200sqm etc)

Pretty much left it to the electrician.

 

As a side note: Scottish BR are way more prescriptive than English and much easier to implement a good design.
