You could consult https://wilkinsoncc.co.uk/ for certainty about your responsibilites.

You could try https://www.ironout.co.uk/

Sorry I don't, you could try third party certificated companies for example https://www.blueskycert.com/installation-maintenance-and-inspection/

Based on my experience it might be from this company? https://www.komfort.com/products/timber-doors-frames/?portfolioCats=173

Does the door security viewer (spy-hole) have an intumescent gasket between the viewer and the core of the door. If it has, that's a good sign that its compliant. If the door is on an escape route, the lock should be a keyless egress (thumb-turn etc). Removal of the viewer and gasket will enable you to inspect the core of the door too.

42mm minimum Check out Certifire certificates of approval for intumescent edge seals.

"As I have mentioned before we have Windsor Type doors with 10 panels per door, 5 at the bottom, up to 80cm x 10 cm wide." Difficult to see a safety issue with clear wired glazing in a door when the glazed panels are only 100mm wide.

Generally speaking, product performnace certification for fire doors does not cover repairs to the fabric of the door. There are certification schemes for repairs and they have limited scope for the extent of a repair. If you are unsure about whether a repair is appropriate, consult a specialist. They can issue a report stating whether the repair is fit for purpose..............or not.

Hi Stu, These are quite common for Flat Entrance Doors but in practice are often locked when the resisdent is at home to avoid an uninvited visitor. From a fire resistance perspective, only doors with evidence of fire performance in an unlatched configuration are suitable. Flat Entrance Doors of course are also held shut with a self-closing device. My understanding in terms of CPR, is that such night latches are outside the scope of CE & UKCA marking. https://www.legislation.gov.uk/uksi/2013/1387/contents However, many fire door manufacturers require that locks fitted to their fire doors are CE or UKCA marked. Therefore, product performance certificate would, in these cases, be invalid.

A BS 8300 compliant door self-closer should provide much easier operation that a standard one.

Assuming the doors are made from timber? You don't say the fire rating for the doors, assuming FD30? You don't say if the self-closers were removed from the top edge or vertical edge of the door? In my opinion: Foams and mastic are unsuitable for filling large holes and voids in fire doors. Use hardwood timber (min density min 640 kg/m3) tightly fitted without any gaps or voids after the repairs have been completed. The very smallest of gaps can be filled with intumescent mastic or fire rated woodfiller. Quality of work should be the same as expected from a skilled joiner, so that once painted the repairs are undetectable without close examination. I wouldn't recommend repairs to the top edge of the door, if its in a life-safety critical location. Replace instead. Keep records of the work carried out and details & certification for the products used.

Refer to the earlier post in this thread. In such circumstances, there is no requirement to replace hinges for the sole reason that they do not carry a CE / UKCA mark.

More worrying that the 'inspector' failed to comment about the disconnected self-closer!!! That's far more serious than an excessive door to frame gap. The gap issue can usually be best rectified by adjustment of the door frame jamb. But subject to survey, lipping replacement might be possible.

In terms of "permissable", the potential references would be 1) The product data sheet or technical manual for the door or 2) The third party certification repair techniques. In both cases the answer would be NO because the aim is to maintain a standard of condition at which the door could be successfully tested in a furnace to the relevant test standard. However, in terms of risk assessment of the performance of the door in its built environment - you may decide the repair could be adequate?
