Digbeth

Hello, I have been asked by the management company of the block to provide a BM Trada Certificate for my front door which leads onto a communal door. As the front door is the original one (1960s ex LA flat) I do not have such a certificate, which I understand are provided for replacement doors only, although the existing door may still be adequate as it has smoke seals, closer etc. What would be the typical cost for a fire inspector to initially assess a single door and provide me with a report (with necessary recommendations)? I am based in Nottingham and the nearest inspector I could see online is based in Leicester. I have tried to find this out by looking at websites but no prices are listed. Would a further inspection report be needed after any upgrade work, presumably with a 'satisfactory/safe' rating, if that is how reports are scored ? Kind regards,
