Recent High Court decisions suggest that contractors will struggle to successfully challenge the costs of an implemented and effective remedial cladding solution, especially one based on expert advice.
The Ȧ Safety Act 2022’s reform of building safety legislation was needed well before the Grenfell Tower disaster in 2017 – but it took a major disaster to force the issue. The contributory causes and responsibility for the fire were many, and the government comes out badly now that the inquiry has heard from six groups whose roles and actions have been under scrutiny.
This is a “rogues gallery” scenario. It foreshadows the apportionment of the risk and responsibility that we shall see once the inquiry report is published and will lead to prosecutions and more.
A couple of important comments from the inquiry show the direction of travel.
In June 2022 Jason Beer KC, on behalf of the Department for Levelling Up, Housing and Communities, admitted during closing submissions to the Grenfell Inquiry that the government failed to provide sufficient oversight of a regulatory system that could have prevented the fire. He outlined four reasons the government missed opportunities to look into whether the regulatory system was operating effectively: a lack of formal oversight, a reliance on industry, departmental financial constraints and the government’s anti-red tape policy.

Stephanie Barwise KC, representing the bereaved and survivors, said: “It is therefore fundamentally misleading to characterise the parlous state of the building regulations as an unfortunate by-product of a prolonged lapse in concentration by the department’s officials, tinged with some unspecified ministerial responsibility and a degree of austerity. It is more than that.
“The evidence points to wilful blindness and complacency towards safety, which was subjugated to the more pressing and politically appealing housing and deregulatory agendas.” Strong words indeed.

Stephen Hockman KC, acting on behalf of Arconic, which sold the cladding panels used on Grenfell Tower, told the inquiry that the evidence of a number of witnesses “lacks plausibility”. He suggested that, even before the Grenfell fire, no one was willing to face up to the legacy issue of buildings with combustible materials and how that might be resolved.
Hockman submitted: “What happened at Grenfell was truly a storm in which the ACM panels were but one component of the maelstrom.”
Professor José Torero pointed out how the guidance for interpreting cladding fire tests had been “full of mistakes from beginning to end”. And Professor Luke Bisby said that the regulatory framework “encouraged” builders to “exploit guidance in pursuit of profit and that “part of the reason … is that no emphasis was placed by the regulatory regime or by the relevant government department on the need for test data to be collated and shared transparently”. There was an over-reliance on individual product testing, rather than looking at how products work together in a much larger system like the one that was installed on Grenfell Tower.
Another inquiry KC, Tim Green, submitted that the government’s decision to ban the use of combustible products following the Grenfell fire was taken without the benefit of the expert evidence from the inquiry, and without a full understanding of the unintended consequences.
Waking watch costs too
We have now had two decisions to shine some light on all this as well as a tribunal hearing on what happened during the Olympic Village’s conversion to residential use.
The first case is Martlet Homes Ltd vs Mulalley & Co Ltd. This was the Technology and Construction Court’s (TCC) first judgment on fire safety of external wall insulation, or EWI, and was handed down in July 2022.
It concerned a contract to refurbish five tower blocks in Gosport with an external wall Sto render insulation system that included combustible expanded polystyrene insulation (EPS), fire breaks and render covering.
There were defects in the installation of both the fire breaks and the EPS. The building owner, Martlet, replaced the system with non-combustible external wall insulation and claimed the cost of doing so – and the waking watch in the meantime – from its contractor Mulalley.
The TCC has plainly demonstrated that it will take a firm view on an external wall system’s compliance with Ȧ Regulations in force at the time of construction
Mulalley in turn denied liability, saying the real cause for the remedial works was Martlet’s recognition, triggered by the Grenfell fire, of the risk posed by the Sto system, which (being combustible) did not meet the enhanced fire safety standards in force after the works were completed and which were further heightened following Grenfell.
Mulalley also contended that the only work necessary to rectify the installation defects involved cutting out and replacing the fire barriers, installing additional dowels through the EPS and re-rendering.
In response, Martlet argued that the Sto system was in breach of specification at the time of installation by Mulalley.
HHJ Stephen Davies considered the Ȧ Regulations 2000 and 2010, BRE 135 (1988 and 2003 editions), Approved Document B (2002 and 2006 editions) and the BBA certificates relating to the Sto system (1995-2017). He decided that:
1. Martlet succeeded in proving both the existence of the installation defects and the specification breach case.
2. Martlet was entitled to recover the cost of the non-combustible external wall insulation system.
3. The waking watch costs were recoverable. They were a reasonable step taken in mitigation of the far greater loss that would have flowed from an evacuation of the towers.
The TCC has plainly demonstrated in this decision that it will take a firm view on an external wall system’s compliance with Ȧ Regulations in force at the time of construction. I am sure it has set an enduring precedent in future cladding claims and related fire safety remediation cases.
Most recently, on 23 December 2022, the TCC gave judgment in the case of LDC (Portfolio One) Ltd vs (1) George Downing Construction Ltd; (2) European Sheeting Ltd (in liquidation). It has provided yet further invaluable insight into the approach the courts will take to the host of cladding claims and liability issues around them.
The case involved recladding and associated remedial works to cure fire safety and water ingress issues in relation to the external wall construction by the claimant (LDC) of three halls of residence over 18m high, built in Manchester in 2007-08. The first defendant (Downing) was the main contractor, and the second defendant (ESL) was a specialist subcontractor responsible for the external wall construction, including the cladding and rainscreen works. By the hearing, ESL had entered creditor’s voluntary liquidation and was unrepresented.
Subcontractors also at risk
The freeholder initially pursued the defendants under the terms of two collateral warranties for the cost of rectifying the The freeholder initially pursued the defendants under the terms of two collateral warranties for the cost of rectifying the defects. The freeholder managed to settle its claim with the contractor and thereafter sought recovery from ESL, for the cost of remedial works (about £16.4m) and loss of income (£4.6m). The contractor also sought an indemnity and/or contribution from ESL for the same defects pursuant to its subcontract.
LDC’s case was that there were: i) numerous defects in the external composite cladding elevations; and ii) fire barrier and fire stopping issues on all elevations.
The TCC was asked to consider several issues, including the scope of ESL’s subcontract obligations to comply with the Ȧ Regulations 2010 (BRs).
The main contract required Downing to comply with “all statutory requirements” which included the BRs. ESL argued that, as there was no equivalent obligation in its subcontract, it had no general obligation to comply with the BRs. Instead, it said it was only liable for design matters if it failed to exercise reasonable skill and care.
A duty to exercise reasonable skill and care is likely to be construed as a minimum requirement only
But the TCC disagreed. It referred to the subcontract, which stated that ESL was obliged not to place Downing in breach of its obligations under the main contract (a common clause). A reasonable skill and care clause could not supersede this obligation.
If two contract clauses could potentially impose different standards, the court said, the clause imposing the lesser standard should be treated as a minimum requirement. Therefore, as the cladding did not comply with the BRs, ESL was in breach of under the subcontract.
The court found for the freeholder, which was entitled to recover £21m from the subcontractor for the cost of remedial works and loss of income. The contractor was also entitled to an indemnity from the subcontractor, as it had put the contractor in breach of the main contract. The TCC added that, in the absence of an indemnity, it would still have held the subcontractor liable under the Civil Liability (Contribution) Act 1978. So watch out, subbies!
ESL also argued that LDC’s remedial works failed to mitigate its loss and that the cost of the remedial works was “unreasonable”. However, on the basis that (i) LDC had relied on expert advice in deciding to carry out the works, (ii) the works were effective to cure the defects and (iii) the works complied with the updated BRs, the TCC held that ESL had failed to demonstrate that the remedials were unreasonable.
The court also endorsed the decision in Martlet which said the courts would not be too critical of a choice of remedial works if that choice was made as a matter of urgency. So, following good expert advice is key.

>>Ȧ the Future Commission: introducing the building safety stream
This decision shows that the courts are continuing to take a robust approach to liability attribution in cladding defects claims and are committed to dealing with cladding and fire safety defect claims firmly, exposing contractors. A duty to exercise reasonable skill and care is likely to be construed as a minimum requirement only, and one which does not derogate from the designer’s strict obligation to comply with the Ȧ Regulations.
A new Triathlon at the Olympic Park
Next in this trilogy is Triathlon Homes vs Get Living. Get Living is the owner of London’s Olympic Village and is being pursued for £27m-plus by Triathlon to improve fire safety standards, in a dispute underlining the slow progress of implementing improvements six years on from Grenfell.
Triathlon Homes is a housing association which leases and manages 1,379 affordable apartments from Get Living on the Olympic estate. It claims that Get Living, as the present owner of the site, is responsible for fire safety remedial work.
Triathlon has applied to the First-Tier Tribunal (Property Chamber) for an order that would force Get Living to accept responsibility for funding all the necessary work as it is Get Living’s case that Triathlon has never been willing to fund its share of the cost.
The dispute underscores one of the major current challenges, namely determining who should pay to repair flat blocks built years ago and that have since changed hands
The dispute underscores one of the major current challenges in solving the safety crisis exposed by the Grenfell fire, namely determining who should pay to repair flat blocks that were built years ago and have since changed hands. The uncertainty is at present unavoidable. Every side is finding its way.
Of the 66 blocks on the Olympic estate, rebadged East Village, 16 still await cladding safety certificates that banks require to fund mortgages, and also fire safety sign-off. Triathlon’s case relates to the five blocks it manages.
Of the estimated remediation on the blocks of £27m in total, about £16m is associated with the properties managed by Triathlon, with the remaining £11.5m for properties owned and managed by Get Living.
Get Living is the majority shareholder in the management company for the East Village, EVML, which is responsible for maintaining shared parts of the estate as well as fire safety. Triathlon has a minority stake.
It seems EVML has applied for £13.5m from the government’s Ȧ Safety Fund (BSF) managed by the DLUHC to cover the majority of the cost of work to Triathlon-managed properties.
As I see it, Triathlon’s case reflects anxiety that it will ultimately be hit with the cost of repairs, with the company stressing that BSF funding is not guaranteed, and may not cover the full cost of works. Triathlon claims it should not have to pay because it is a leaseholder from Get Living, the freeholder.
If the tribunal concurs, this will relieve Triathlon of the liability of costs and enco
