** Main Story**

So, Siderise, the insulation manufacturer, is actually taking Kensington and Chelsea Council to court. Can you believe it? They’re challenging a ban that prevents them from doing any work for the local authority. This all goes back to the Grenfell Tower refurbishment, where Siderise supplied cavity barriers, and we all remember how that ended; a tragedy that claimed 72 lives. The inquiry afterwards? It exposed some pretty massive failings in building regulations and the use of flammable materials, as you know.

The Council’s Reasoning and Siderise’s Defense

The ban itself came down in December 2024. Kensington and Chelsea Council, after similar bans against other companies that were involved in the refurbishment like Rydon and Kingspan, prohibited Siderise from being able to work in the area. Now, the council hasn’t exactly shouted their reasoning from the rooftops, which is not that surprising. However, it’s pretty safe to assume it’s tied to the Grenfell Tower Inquiry’s findings. Okay, so the inquiry didn’t find Siderise guilty of, you know, deliberately misleading anyone. But, they did point a finger at Siderise’s datasheets for implying their cavity barriers were always effective in rainscreen cladding systems. The Council says that it decided to take action against companies whose incompetence, dishonesty, or misleading behavior contributed to the Grenfell Tower fire, or you know, its spread. And you can understand that, can’t you? You’ve got to send a message to the industry.

However, Siderise is not happy with this at all. In fact, they strongly deny all of this, arguing that the council’s decision is completely baseless, and that there isn’t any foundation or justification for it. They’re really emphasizing that the inquiry itself explicitly said that neither Siderise nor its products actually contributed to the fire’s spread. Furthermore, they highlight they’ve been really proactive in adopting new industry standards, so nothing like this can happen ever again. I mean, they point out that, yes, their products were used in the refurbishment, but that doesn’t mean they were responsible. The inquiry report is pretty clear that neither they, nor their products had a part in that tragic fire or its spread. There is also no suggestion that Siderise wasn’t being candid before the Inquiry. It’s a complicated situation, isn’t it?

Legal Arguments and Implications

Siderise is now seeking a judicial review, saying the council’s decision breaks its own rules, is, well, irrational, and it completely misinterprets the Grenfell Inquiry reports. Plus, Siderise argues the ban breaks the Public Contracts Regulations 2015. That said, the High Court is going to hear the case next month. Should be interesting to see how that goes down.

On top of all this, it has broader significance for the ongoing changes to UK building regulations. We all know the Grenfell Tower fire highlighted pretty serious flaws in the current regulatory framework, which is why there’s been loads of comprehensive reforms. For instance, The Building Safety Act 2022 created brand new dutyholder roles, stricter building control systems, and made a “golden thread” of information a requirement throughout a building’s lifecycle. They also introduced a new building control regime for higher-risk buildings or HRBs, with the Building Safety Regulator now in charge of building control for these structures.

Impact on the Industry as a Whole

Now, the outcome of Siderise’s challenge is going to have major ramifications for the construction industry. If Siderise wins, local authorities might find it harder to impose bans based on involvement in projects where regulations have been broken, unless they can prove direct blame. On the other hand, if Siderise loses, it’ll really reinforce the power of local councils to prioritize safety and accountability within their jurisdictions.

The way the UK building regulations are changing is reflecting a pretty serious commitment to making sure there isn’t another Grenfell-like tragedy. These changes are supposed to build a culture of safety in the construction industry, making sure accountability for building safety is a top priority on every single project. Siderise’s case is a major moment in how building regulations evolve. It’s testing the balance between responsibility, accountability, and, of course, due process after a national tragedy like Grenfell. Whatever the High Court decides, it’s definitely going to influence the conversation surrounding building safety and how we understand the Grenfell Tower Inquiry’s findings. It’s a lot to unpack, isn’t it?
