Q&A Building Compliance Round Up 2026 Webinar

Building Compliance Round Up - Q&A 2026
21:58


Following our recent Building Compliance Round Up 2026 webinar, we've gathered answers to the questions submitted by attendees during the live session. The webinar explored key compliance challenges, emerging risks, and regulatory developments affecting the built environment.  

Our expert panel included Robert Thilthorpe from the Fire Industry Association (FIA), who discussed plug-in solar panels, battery storage, and associated fire safety considerations; Denley Nunn of Cygnus Systems, who provided insight into the Interim Measures Alarm Fund (IMAF) and interim fire alarm solutions; and Steven Wilson, Technical & Compliance Director at Ventro, who delivered a roundup of key regulatory updates, including the Building Safety Levy, Awaab's Law, BS 7671 Amendment 4, and changes to Approved Document B.

Below, we answer some of the most frequently asked questions from the session and provide practical guidance on the topics discussed.

Q1: For a rental property, could tenants ask their landlord for permission? Alternatively, if the back garden is large enough and has no trees, could they be placed there to reduce the risk if they catch fire?
Yes, tenants can request permission from their landlord, and we would recommend this being best practice. Any necessary landlord, freeholder or planning consent should be obtained before installation. A garden may be a suitable alternative, but the absence of trees is not, by itself, evidence that the installation is safe. Our recommendation would be to check the approved mounting method, separation from combustible materials, cable route, weather exposure and the manufacturer’s instructions before agreeing a location. Only a compliant product should be used; this does not cover plug-in batteries. Worth noting that you might move the risk to your neighbours, depending on the garden specifically!

Q2: How can the problem of festooning cables be addressed?

A competent contractor should assess the complete cable route and its supports, not just the cables themselves, against BS 7671 Regulation 521.10.202. If the question instead concerns loose solar-panel leads, we would always recommend a planned, securely supported route that avoids trip hazards and damage, with the connection arrangement checked against the product instructions.  

 

Q3: What about HMOs, where each room is classed as a separate household?
We would not treat each separately let room as automatically entitled to its own system. The relevant network connection and the building’s electrical installation need to be checked; Ofgem’s network approval does not, by itself, establish electrical safety within the premises. Our recommendation would be that the landlord asks a competent electrician and the distribution network operator to confirm the permitted arrangement for the particular HMO before residents connect equipment, especially where rooms share circuits or a supply.

Q4: For HRBs, do BSC reports need to be updated each time a resident has these installed, due to the impact on the fire load? Is planning permission required if a resident clips them over the balcony balustrade?
This is a great question, our recommendation would be that the principal accountable person reviews the proposed installation and records its effect on those risks, updating the assessments and report where necessary; We would not assume that every installation requires a complete report rewrite. Clipping panels to a balcony does not establish that planning permission is unnecessary: Government guidance expressly identifies these permissions as matters to check before installation. 
 
Q5: Robert, does the FIA offer training for installers with no previous experience?
Yes. The FIA’s Level 3 BS 5839-1 Fundamentals Qualification is aimed at new and aspiring fire detection and alarm technicians and provides an introduction to the sector and the standard. It comprises two training units and an examination. It is worth noting that FIA training would focus on fire safety specifically, if you are exploring training for electrical works then the ECA are a great organisation for electrical training. 

Q6: Can an alarm system can replace a waking watch?
Yes, this is the purpose of IMAF. A BS 5839-1 L5 interim alarm can replace a waking watch, or reduce the need for one, provided the fire risk assessment supports it and the other mitigation measures are in place.
 
Denley Nunn, Cygnus, speaking on webinar
 
Q7: Would this retrospectively cover alarms installed to remove a waking watch? In this case, the alarms were installed in May, and the fire risk assessor and fire service signed off the removal of the waking watch in July.
No. IMAF doesn’t fund alarms that are already installed. Homes England confirmed this in August. Buildings that have already had Waking Watch Replacement Fund money aren’t eligible either.
 
Q8: Can a temporary L5 system be installed in an HRB without BSR approval, with a GW application submitted retrospectively? Given the known delays with BSR applications, could this be a fair and cost-effective approach when time is a priority?
No. You need BSR approval before work starts, and there’s no retrospective sign-off route for HRBs. The emergency repairs exemption covers repairs, not new systems. 
 
Q9: Who should carry out the survey if my organisation plans to install IMAF in some of our buildings?
 A competent, third-party accredited fire alarm company should survey, design, install and commission the system to BS 5839-1 L5. The quote has to come from a company on the IMAF approved panel. Involve your fire risk assessor too, since the FRA or FRAEW has to identify the need for the alarm.

Ventro are approved IMAF installers and our sister company Firntec are able to carry out all relevant surveys required for your application.
 
Q10: Has the performance of wireless systems in concrete buildings improved?
Yes. Modern systems use mesh networking, so every device relays signals and there are multiple routes back to the panel. That makes them far more resilient in concrete and steel structures. A radio site survey is still essential, as per BS 5839-1.
 
Steven, Ventro Group, speaking on Webinar
 
Q11: Steven, I understand that the levy applies to new buildings. For student accommodation that meets the criteria, does it apply only to new buildings, or to existing buildings as well?
For England’s Building Safety Levy, it is not limited to constructing an entirely new building. Qualifying development that creates new purpose-built student accommodation bedspaces through an extension or conversion of an existing building can also fall within scope, subject to the charging conditions, exemptions and transitional rules. An existing student building does not attract the levy simply because it exists or remains occupied. Work that does not provide new dwellings or new purpose-built student accommodation bedspaces is outside the levy information and charging requirements described in the developer guidance. I recommend confirming the treatment of the specific proposal with the collecting local authority. 
 
Q12: For legacy PoE installations designed and installed before BS 7671 A4, what is expected in practice? Are organisations expected to assess these systems retrospectively against the new requirements? If so, what should the review cover, and what would trigger remedial action?
As a practical review, our recommendation would be that a competent electrical specialist checks the original design and test records, power-source suitability, connected loads, cable and connector ratings, bundle sizes and operating temperatures, environmental conditions, supports and fire-stopping. Remedial action should follow identified danger or deterioration, overheating or damage, unsuitable components, or a proposed increase in load that the existing installation cannot safely support, not its age alone. Record the findings, any limitations and the reasons for action or continued use; confirm the detailed assessment against the published standard before issuing this answer.
