I can’t imagine the difference between the tests in order to approve one for domestic and not for commercial. I would be very interested as I may have to rip out 40,000 doors.

Something does not sound right. The gaps may now be correct, but if it can no longer function as a door, it’s no use to man not beast. The closer should be strong enough to latch the door without slamming and it should be easily openable (30N). Try smearing a thin film of petroleum jelly on the fin seal as they are sometimes stiff when first fitted.

Yes a FRA is still required as there is a higher risk of arson etc. You still have a duty of care to trespassers Fire Safety For Empty Buildings - Dorset Fire Protection

Without accelerant the surface spread of flame over a glass panel would be zero as glass is none combustible, however the surface coating and/or frame/panel holding the glazing in place would need a statement from the supplier/installer/manufacturer

The only thing I can think of is if your door encroaches on to the final exit door when it is opened, that could probably be solved by hanging the door the other way.

Are you breaking the law? Technically yes, but I doubt that the fire police will ever inspect the property again. The issue will be if you ever have a fire, it will invalidate the insurance and may lead to prosecution as you have knowingly removed a life safety device, or when you sell the property they will have to be replaced. There are alternatives such as a suppression system, but all are far more expensive

You need BR Appendix C, table C1 page 153

A competent fire door inspector would be able to make an opinion as to whether a fire door is up to standard by a visual inspection to declare the door as a “Nominal” fire door based on the weight thickness and construction. Usually, a monthly fire door check is little more than a visual user inspection looking for obvious defects. There should be a 6 monthly inspection the checks all aspects of the door including gap sizes. The gaps of +2 to +4 have been standard for at least the last 20 years, Attached from a Halspan certificate January 2008

On a further point As for the door certification, this is a legal requirement under regulation 38 and should of been included in the OEM pack at handover by the developer.

I have to agree to a certain extent with the developer, the fire doors should have been inspected every six months (BS 9999, I.6.2 Fire doors) they should have been inspected 12 times. Did any statutory inspection pick up these defects? And why did you not go back to the builder with this information. You may have recourse to the party that conducted the previous risk assessments for the building if they did not highlight the defects to the doors.

To ensure that the door fits, each door is measured. Lead times are currently running at 8 to 12 weeks for a fully certified door. Generally, the have a range of standard door sizes, but you still have to measure the opening to find out which standard door will fit. We have several options whilst waiting for a delivery, enhance repair the door, replace with a blank door, close the bedroom, close the flat, close the building or keep a waking watch.

From what I have found in my experience, even with modular builds, off the shelf doorsets seldom fit without modification. That’s why we measure every door that fails before ordering the new door. It works out cheaper in the long run.

All fire doors must be either 1 Self closing 2 Keep locked shut Perko closers are no longer permitted as closers on fire doors since they don’t latch the door from a narrow angle.

That's why you survey, measure the door and then order the correct size

There should be minimal adjustment to the leaf or frame if the door is correctly measured. The frame should be fixed and seal to the opening giving a door to frame gap of 2 to 4 mm. As Neil says if the surveyor dose a decent job there should little adjustment, unless you are installing door blanks

If it is only a toilet then no, if it has a cloakroom attached then yes

Provided you get building reg approval, as many as you want.

Flat entrance, this should be a FD30S door, it maybe a nominal door if it gives the same protection. (No holes, approved letter box, 3 hinges, etc) If the flat is in shared occupancy, then it’s a HMO, and all bedroom doors must be fire rated unless they are living as a family.

Duplicating the doors to make a lobby is not an issue providing that they open to a minimum of 90deg so as not the encroach on the existing doors. You may want to duplicate the fire exit signage above the doors

So basically for the buildings shown constructed of sandstone blocks and brick, its not an issue

Building regulations say that when building work is undertake on an existing building it should ensure that the building is no worse in terms of compliance than it was before the work started. However, there is no requirement to improve the levels of compliance. It is an established principle that building regulations should not be applied retrospectively. The ‘non worsening’ clause recognises that it may not be feasible to try and apply modern standards to old buildings. If it was compliant, then it still is compliant as the changes to cladding are only above 11m

Its only an issue over 11m

All depends on the size of the room, the location in the building, is it on a dead-end, what is the process. But you could start by looking at inner rooms.

But it can be used as the basis of an argument
