TCC allows Building Liability Order based on an Adjudicator’s Decision and an ‘Anticipatory’ Building Liability Order

By Mike O’Connor & Kate Knox
Building liability orders (BLOs) are still a relatively new creation and the law around them is very much in its infancy. We now have the second reported case of a BLO being ordered: Crest Nicholson Regeneration Limited and Ors v Ardmore Construction Limited (in administration) and Ors [2026]. The first being in the case of 381 Southwark Park Road RTM Company Ltd & Ors v Click St Andrews Ltd & Anr [2024]. Crest Nicholson Regeneration Limited obtained an adjudicator’s decision against Ardmore Construction Limited (ACL) for circa £14.9M in relation to external wall defects at a development known as Admiralty Quarter in Portsmouth. At the same time, both Crest and ACL and various ACL associated companies are parties to legal proceedings concerning allegations of defects (including the fire safety defects) at the development. Crest applied to the Court for a BLO against ACL’s associates in respect of the adjudicator’s decision and also an ‘anticipatory’ BLO in respect of the ongoing legal proceedings and any liability for which the Court ultimately decided ACL owed.

The Court’s Decision
The Court:
- accepted that an adjudicator’s decision can constitute a relevant liability (without Crest needing to apply to the Court for summary judgment) and duly issued a BLO against the associate companies of ACL, for circa £14.9m; and
- decided that it was just and equitable to also award an anticipatory BLO against ACL’s associate companies named as co-defendants in the ongoing proceedings, despite the associates’ various arguments for waiting until the conclusion of those proceedings before making any such order.

What can we learn from the latest case concerning BLOs?
Relevant Liability and Adjudicator's Decisions
As a reminder, a BLO is a statutory remedy introduced by the Building Safety Act 2022. It allows the Courts to extend liability incurred under:
- the Defective Premises Act 1972 or section 38 of the Building Act 1984 (not yet in force), or
- as a result of a building safety risk (being a risk to the safety of people in or about the building arising from the spread of fire or structural failure).
The Court found that it was sufficient that the adjudicator had found that the extent of the fire safety defects in the external walls rendered certain dwellings unfit for habitation and consequently breached the Defective Premises Act 1972. Interestingly, the Court also agreed with Crest that the failure to comply with an adjudicator's decision was also itself capable of being a 'relevant liability'. The temporarily binding nature of an adjudication decision did not prevent the Court from finding that it was a 'relevant liability'. If it later transpired that an overpayment had been made, the associates could claim in restitution for the return of the moneys ordered to have been paid. Notably, Crest was also willing to give an undertaking in respect of any such overpayment, insofar as necessary. That doesn’t mean to say that the Courts will always determine that it is just and equitable to find that an adjudicator’s decision constitutes a relevant liability. The Court noted that it should be considered on a case-by-case basis.
Anticipatory BLOs
Interestingly, the Court characterised the award of an anticipatory BLO as stage one of a two stage process. The second stage would be the conversion of the anticipatory BLO into one which is ultimately enforceable, giving the Court an opportunity to:
- consider the relative factual blameworthiness of the parties at that point, and
- decide whether to reduce the proportion of liability at the point of transmission to the associates.
Just and Equitable Test
The associates of ACL raised various arguments to oppose the application, notably including:
- As Crest was a commercial developer and was not an individual leaseholder, an impecunious management company, a charity or a social housing provider etc., it was not the sort of entity in whose favour it is just and equitable to grant a BLO.
- ACL overall made a net loss of £1.94m on the development such that no profits would have gone to the associates from the development. In comparison, it was alleged that Crest had made a substantial profit on the development.
- That, by making an anticipatory BLO in this case, it would create a queue of other parties seeking anticipatory BLOs against the associates, with the likely knock-on effect of making borrowing or raising money for performance bonds more difficult.
- The substantial extent of the Ardmore Group's overall contribution to fire safety remedial works across 49 projects.
Regarding ACL's comparative profits argument, the Court noted that there may be other situations where, amongst other factors, a significant disparity in financial heft between applicant and respondent could be a matter which weighs in the balance, but they did not consider that to be the case presently. The Court afforded no weight to the argument that discretion should be exercised because of the likely knock-on effect on the associates’ ability to borrow or raise money for performance bonds. The Court ordered the anticipatory BLO on a joint and several basis, noting that the Court could still decide whether to reduce the proportion of liability at the point of transmission to the associates at the second stage in the process, once ACL’s liability has been determined in the ongoing proceedings. This case continues the general trend of the Courts and the First Tier Tribunal’s willingness to support the measures brought in under the Building Safety Act 2022.
