- According to building regulations, all habitable rooms above ground level have to have a means of escape. In the case of a single storey dwelling (e.g. a bungalow) there should be 2 exits (so a front and back door), and if not then the habitable rooms have to have a means of escape as well.

2. Now that door closers are no longer necessary within dwellinghouses do I need them in an HMO?
The Housing Act 2004 replaced the previous housing fitness standard with a statutory framework for assessing and tackling hazards in housing - including fire hazards. Within a house designated as a ‘House in Multiple Occupation’ such devices may still need to be provided between the private areas (i.e., bedrooms) and the common parts (i.e., circulation spaces, living room, kitchen etc). Further guidance on fire safety provision can be found in the Local Authorities Coordinators of Regulatory...
3. When providing a protected stairway in a dwellinghouse, do I need to fit fire doorsets on the cupboards and bathrooms?
A protected stairway should be enclosed with fire resisting construction and fire doorsets in order to protect people escaping down the stairs from a fire in the accommodation. It may not always be necessary to provide fire doorsets on cupboards if they are small and the fire risk is low. An alternative to providing a fire doorset on a bathroom is to include the bathroom within the stair enclosure, thus removing the need for a fire doorset.

Diagrams 5.2a (Volume 1) and 8.2a (Volume 2) of Approved Document B apply a more onerous standard than Diagrams 5.2b and 8.2b, any combustible (including thermosetting) core panels should incorporate a band of material rated A2 -s3, d2 or better 300mm wide centred over the wall.
8. Diagram 5.2b (Volume 1) and 8.2b (Volume 2) of Approved Document B (Junction of compartment wall with roof) places restrictions on double skinned insulated roof sheeting with a thermoplastic cor...
In low-rise residential, office or assembly buildings to which Diagram 5.2b (Volume 1) and 8.2b (Volume 2) applies, panels with thermosetting cores can be used without a 300mm band of material A2 s-3, d2 material. However, fire-stopping must be provided to seal the joint between the compartment wall and the underside of the panel. Any voids above the panel (such as where an additional roof covering is provided) should also be adequately fire-stopped.
9. If an existing single storey shop is extended so that it exceeds the maximum 2000m2 compartment size, is it necessary to install a sprinkler system?
Regulation 4 (1) of the Building Regulations 2010 states that “building work” should comply with the applicable requirements contained in Schedule 1. Regulation 4(3) then goes on to state that after the work is completed the building as a whole should comply with the applicable requirements of Schedule 1 or, where the building did not previously comply with any such requirement, is no more unsatisfactory in relation to that requirement than before the work was carried out. Where an existing s...
15. Note 3, in Table 10.1, of Section 10 in Approved Document B Volume 1
states that “Timber cladding at least 9mm thick is also acceptable” to be used in some external surfaces 1000mm or more from the relevant boundary. Does this allowance apply to all cases where timber is used on the outside of a building? Designers should consider factors that can influence the fire performance of timber cladding, including form, orientation, presence of cavities, and combination with other materials (e.g. substrates) when reviewing this allowance for a particular building sit...
16. Is my reaction to fire classification for a product relevant to all situations?
The reaction to fire classification according to BS EN 13501-1:2018 is a composite classification, derived by using outcomes from multiple test standards, including the single burning item (SBI) test according to BS EN 13823:2020. For more information on the reaction to fire classification and its derivation, guidance is provided in BS EN 13501-1. The reaction to fire performance which uses an apparatus such as the SBI test is not only a function of the material or product used, but also a fu...
17. Why is the maximum hose distance in paragraphs 13.2a in Volume 1 and 15.1 in Volume 2 of Approved Document B 45m? Our local Fire and Rescue Service appliances are fitted with hoses which are mu...
The 45m criterion is based on the physiological demands on firefighters engaged in search and rescue and on the restrictions that may be imposed by their equipment. When considering hose length, it is important to appreciate that, in practice, hoses have a tendency to ‘snake’ when charged thus limiting their effective length. It is also common practice to trim the ends of hoses where they become damaged. The time and effort it takes to lay out a hose may also be an important factor.
18. Is the recommended 45m distance in paragraph 13.1 in Volume 1 of Approved Document B for access for a pumping appliance measured from the front door of a dwelling?
Paragraph 13.1 in volume 1 of Approved Document Part B states there should be vehicle access for a pump appliance to within 45m of all points within dwellinghouses. This is to take account of the actual distance that the firefighters need to carry kit and lay hoses from the vehicle to reach a potential fire.
19. If the 45m recommendation for firefighting access in paragraph 13.1 in Volume 1 Approved Document B cannot be achieved to all points within the dwellinghouse would the provision of a private fi...
Provision of water supplies does not, on its own, reduce the physiological impact on firefighters of travelling long distances whilst carrying heavy equipment. Water from private hydrants may still need to be pumped before it can be used for firefighting. Where it is proposed to adopt an alternative approach to meeting requirement B5 (Access and facilities for the fire service) It would be advisable to seek the advice of the fire and rescue service who can advise on the practicalities of fire...
21. Can I apply the guidance in Approved Document B for combustible structures (e.g. timber) in meeting the requirements of the building regulations?
Designers should discuss and agree the design intent and the necessary evidence with the building control body before starting building work. As set out within Approved Document B, the guidance is provided for common building situations. Tall, large, or complex buildings, where the structure is able to contribute as a source of fuel during a fire, are not common building situations and present additional considerations which designers should have regard to. The designer should consider the ty...

23. Approved Document B references an older version of a named standard, should I use the newer version?
When an approved document refers to a named standard, the relevant version of the standard is listed at the end of the approved document. Until the approved document is amended, these references are part of the guidance approved under section 6 of the Building Act. If work complies with the guidance referred to in the approved document, that makes it likely that the work conforms with the relevant requirements of the Building Regulations. Following other guidance would not provide that legal...
