Subject: Part L Compliance

Discipline: Electrical

You are working on a new-build block of apartments, currently at design stage. The common areas are currently intended to be unheated, and have been designed as such. The Client has asked for electric panel heaters to be added to the design of the common areas. What consequence does this have to other aspects of the design (considering both MEP and/or other members of the design team)?

Possible Answers:

A heated common area must comply with the guidance of Approved Document L2 (as per Approved Document L1 clause 0.4.a). Please note that an unheated common area does still have minimum fabric requirements. An unheated common area must comply with App Doc L1 minimum fabric requirements (as per App Doc L1 clause 0.4.b).
