The 微密圈 Safety Act 2022鈥檚 reform of building safety legislation was needed well before the Grenfell Tower disaster in 2017 鈥� 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 鈥渞ogues gallery鈥� 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鈥檚 anti-red tape policy.

Stephanie Barwise KC, representing the bereaved and survivors, said: 鈥淚t 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鈥檚 officials, tinged with some unspecified ministerial responsibility and a degree of austerity. It is more than that.

鈥淭he evidence points to wilful blindness and complacency towards safety, which was subjugated to the more pressing and politically appealing housing and deregulatory agendas.鈥� 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 鈥渓acks plausibility鈥�. 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: 鈥淲hat happened at Grenfell was truly a storm in which the ACM panels were but one component of the maelstrom.鈥�

Professor Jos茅 Torero pointed out how the guidance for interpreting cladding fire tests had been 鈥渇ull of mistakes from beginning to end鈥�. And Professor Luke Bisby said that the regulatory framework 鈥渆ncouraged鈥� builders to 鈥渆xploit guidance in pursuit of profit and that 鈥減art of the reason 鈥� 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鈥�. 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鈥檚 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鈥檚 conversion to residential use.

The first case is Martlet Homes Ltd vs Mulalley & Co Ltd. This was the Technology and Construction Court鈥檚 (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 鈥� and the waking watch in the meantime 鈥� from its contractor Mulalley.

The TCC has plainly demonstrated that it will take a firm view on an external wall system鈥檚 compliance with 微密圈 Regulations in force at the time of construction

Mulalley in turn denied liability, saying the real cause for the remedial works was Martlet鈥檚 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 微密圈 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鈥檚 compliance with 微密圈 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鈥檚 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 拢16.4m) and loss of income (拢4.6m). The contractor also sought an indemnity and/or contribution from ESL for the same defects pursuant to its subcontract.

LDC鈥檚 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鈥檚 subcontract obligations to comply with the 微密圈 Regulations 2010 (BRs).

The main contract required Downing to comply with 鈥渁ll statutory requirements鈥� 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 拢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鈥檚 remedial works failed to mitigate its loss and that the cost of the remedial works was 鈥渦nreasonable鈥�. 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.

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鈥檚 strict obligation to comply with the 微密圈 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鈥檚 Olympic Village and is being pursued for 拢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鈥檚 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鈥檚 case relates to the five blocks it manages.

Of the estimated remediation on the blocks of 拢27m in total, about 拢16m is associated with the properties managed by Triathlon, with the remaining 拢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 拢13.5m from the government鈥檚 微密圈 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鈥檚 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 encourage Get Living to advance fire safety repairs.

Michael Gove has made it clear that he expects property developers and freeholders to remedy fire safety problems and not pass costs on to leaseholders. Here we are seeing some of the agony offstage. 

The road ahead

Summing up, these two TCC cases show that contractors will struggle to successfully challenge the costs of an implemented and effective remedial solution, especially one based on expert advice. It is not enough to say that the defects could have been remedied through an alternative scheme for a lower cost 鈥� parties will need to show the approach taken was unreasonable.

For some years, many thousands of people have been powerless to move and get on with their lives until remediation takes place, because banks refuse to extend mortgages against properties that have not been signed off as fire-safe.

Basically, who picks up what and pass-the-parcel tactics will continue until more cases settle policy and liability. This illustrates that sharing risk and responsibility is ultimately, in most cases, going to have to be determined by tribunals 鈥� and not over a cup of coffee.
