Some advice needed -
Had a room created in our loft. We notified Building Control before any work started, paid the fee based on the overall project value , and they inspected the build as it progressed.
We were discussing what was needed to comply the whole house from the start but, after the builder had completed his work and been paid, the BCO has added further requirements on each visit.
We knew either fire alarms or fire doors were required and after t5he main work was complete I fitted the alarms which were sited in accordance with the manufacturers instructions and the locations through the house in accordance with the BCO's requirements (every room and every landing). He OK'd positioning and that they were working correctly. He then asked us make further additions (fireproofing attic, cellar and kitchen doors) that had not been mentioned before and when he came to inspect those asked for a certificate for the fire alarms. It was never going to be possible to run a separate circuit for the alarms (this is a victorian house and the rest is fully decorated) and I'm sure I OK'd with him that the alarms would be run from the lighting circuit.
He's now asking for an electrical certificate for the fire alarms which of course I don't have.
