I am installing fire doors throughout the 2 story house except for 2 receptions and kitchen, which will have 15 panel glazed (obscure glass) internal doors. The builder want to charge more on the basis that he will need to install a separate fire alarm in each of the three rooms with glazed doors, otherwise his electrician will not give me electric certificate (I am getting the whole house rewired at the same time). I will not be renting the property. I can't understand what fire doors or smoke alarms have to do with electric NICEIC certificates? Surely the electrician can't fail the certificate just because I installed a non-firedoor with no smoke alarm in that room? Please can you help me with this?
