For anyone involved in high-rise development or large-scale construction in Essex, London, or Kent, the legal landscape just shifted significantly. Earlier this month, the Technology and Construction Court (TCC) handed down its decision in Crest Nicholson v Ardmore [2026] EWHC 789 (TCC). If you’ve been following our previous discussions on Building Liability Orders (BLOs), you’ll know that the Building Safety Act 2022 introduced some aggressive new tools for recovery. However, this new ruling is the first time we’ve seen the courts actually grant "anticipatory" and "adjudication-based" BLOs.
I’ve spent the last week speaking with developers and insurance underwriters across London, and the consensus is clear: the "corporate veil" that used to protect parent companies from the failings of their subsidiaries is no longer just thin, it’s effectively transparent in the eyes of the law.
Why This Case Matters for General Contractor Liability Insurance
In the past, if a Special Purpose Vehicle (SPV) or a subsidiary went bust or lacked the funds to fix a defect, the claimant was often out of luck. The parent company sat safely behind its corporate structure. Crest Nicholson v Ardmore has changed that reality. The court has confirmed that it can, and will, make associated companies jointly and severally liable for building safety risks, even before a final trial has concluded.
For those of us in the General Contractor Liability Insurance sector, this means the risk profile for a construction group has fundamentally changed. It’s no longer enough to insure the contracting entity; the entire group exposure must be considered.
The Rise of Anticipatory BLOs
One of the most striking elements of this July 2026 ruling is the granting of an "anticipatory" Building Liability Order.
Essentially, the court didn't wait for a final determination of liability at a full trial. Instead, it fixed associated entities with liability that is contingent on a future finding against the primary defendant. Legal experts are calling this a "contingent statutory indemnity."
I think this is a game-changer for how we handle claims. Going forward, a claimant in Essex or London doesn't have to wait years for a trial to end before they can start targeting the deep pockets of a parent company. They can secure the BLO early, ensuring that if the contractor is found liable, the money will be there, regardless of whether that specific contractor is still solvent.
Adjudication: The New Liability Trigger
Perhaps even more concerning for contractors is how the court treated adjudication. Usually, adjudication is seen as a "pay now, argue later" mechanism, a temporary fix to keep cash flowing. However, the TCC held that an adjudicator’s decision constitutes a "relevant liability" under the Building Safety Act.
This means that if a contractor loses an adjudication over a building safety risk and fails to pay, that unpaid award can be used to trigger a BLO against the rest of the corporate group.
In fact, I can see this becoming the preferred route for claimants. Adjudication is fast. If they can get a quick decision and then immediately apply for a BLO to bring in the parent company, the leverage they hold over a construction group becomes immense. It bypasses the traditional protections that Business Insurance London policies were designed to manage.
The End of the SPV Shield
For decades, the industry has relied on SPVs to ring-fence risk. It made sense from a business perspective: if a project failed, the loss was capped at that specific entity. But the "just and equitable" test used in this ruling shows that the courts are prioritising the protection of residents and the recovery of costs over corporate formatting.
The court emphasised that BLOs are intended to ensure those responsible for defective work cannot escape liability via corporate structuring. If a primary contractor is under-capitalised or insolvent, the court will look to the "associated companies."
I spoke to a client in Kent last week who was worried about their historic projects from the early 2010s. This ruling confirms that legacy issues can come back to haunt current group structures. If you are part of a group where one subsidiary handled a project that now has fire-safety defects, the entire group is potentially on the hook.
Practical Steps for Essex, Kent & London Contractors
Given this shift, what should you be doing? Maintaining the status quo is a recipe for a massive, uninsured loss. Here is what I recommend to our clients:
- Review Group-Wide Coverage: Ensure your Construction Contractor Insurance actually covers the parent and sister companies for liabilities arising from BLOs. Many standard policies only name the specific contracting entity.
- Audit Your SPVs: Identify which of your historical SPVs might have exposure to fire-safety or building safety risks. Don't assume that because an entity is dormant, the risk is gone.
- Adjudication Preparedness: Since adjudication can now trigger group-wide liability via BLOs, you cannot afford to take these "interim" battles lightly. Treat every adjudication as if the future of the entire group depends on it.
- Avoid the "Inflation Trap": As we've discussed before, underinsurance is a major risk in 2026. Ensure your limits are high enough to cover group-wide liability, not just project-specific risks.
Final Thoughts
The Crest Nicholson v Ardmore ruling is a stark reminder that the legal environment for construction is getting tougher. The courts are clearly aligned with the government’s goal of making the industry pay for building safety remediation, and they are willing to push through traditional corporate boundaries to do it.

FAQ: Crest Nicholson v Ardmore & BLOs
What is a Building Liability Order (BLO)?
A BLO is a court order that makes "associated companies" (like parent or sister companies) jointly and severally liable for building safety risks or defects, even if they weren't the original party to the contract.
What did the Crest Nicholson v Ardmore ruling decide?
It confirmed that BLOs can be granted "anticipatorily" before a final trial and that adjudication decisions can be used as the basis for these orders.
Does my current General Contractor Liability Insurance cover BLOs?
Not necessarily. Most policies are entity-specific. You need to ensure your policy wording accounts for statutory liabilities imposed under the Building Safety Act 2022 on associated companies.
Why is this a risk for companies in Essex and London?
These areas have a high density of developments covered by the Building Safety Act. The ruling makes it easier for claimants to target the assets of larger parent companies based in these financial hubs.
Can an old project from 10 years ago trigger a BLO?
Yes, the Building Safety Act has extended limitation periods for certain defects to 30 years, and BLOs can be applied to these legacy liabilities.
