April 29, 20251 yr comment_48994 Hi friend of mine has a chip shop with apartment below which has its own exit and entrance on the side of the building, he is rewireing both shop and apartment what we need to check is the apartment has smoke alarms and heat detectors install installed coming after lighting circuit does that mean he can use the same domestic smoke alarms and heat detectors in the shop below which means top and bottom will interconnect or does he need a fire alarm system Report

April 30, 20251 yr comment_49013 Sounds like your friend has failed to meet the first legal requirement - that of a fire risk assessment, which would answer your question. See here for advice on the law https://www.gov.uk/government/publications/making-your-small-non-domestic-premises-safe-from-fire Domestic detection isn't usually permitted in commercial premises or for where commercial & domestic premises need to evacuate together, if there is a 60 minute fire resistant ceiling between shop & flat there may be no need to have linked alarms.
