United Kingdom cladding crisis

In the 1980s, the Conservative Government introduced its Deregulation Initiative; in consequence, the Building Act 1984 reduced building regulations from 306 pages to 24. The Housing Act 2004 introduced the Housing Health and Safety Rating System, enabling flexible 'risk-assessment'-based safety standards for rental properties. This was followed by the Regulatory Reform (Fire Safety) Order 2005. Prior to the Order, all public and commercial buildings, and all non-single-household domestic dwellings (apart from houses in multiple occupation), were required to hold a valid fire safety certificate issued annually after an inspection by the public-sector Fire Service. This regime was replaced with assessment by third-party fire-risk assessors contracted by building owners and landlords, with no mandated timeframe for checks, and no mandated professional qualifications. In 2013, the Fire Service found that 14% of risk assessments were non-compliant with the law, and in 2018 it was found that 500 out of 800 of the UK's fire risk assessors were not registered with accredited bodies. In 2006, changes to UK building regulations, intended to facilitate greater energy efficiency at lower cost, arguably made combustible cladding and insulation in buildings over 18 m legal, and opened the way to its widespread use. ==Extent of problems==

Shortly after the Grenfell fire, the Ministry of Housing, Communities and Local Government (MHCLG) established the Building Safety Programme. In the short term, this scheme sought to identify and remediate buildings with unsafe cladding. The problems that it variously exposed, compounded, and remedied constitute the cladding crisis. The programme is, longer-term, leading to a new regulatory framework for building safety, a Building Safety Bill, and a new Building Safety Regulator. In June 2020, the Housing, Communities and Local Government Select Committee estimated that thoroughly remediating fire safety defects in UK buildings over 18 metres alone might cost around £15 billion. ACM cladding attends a false alarm at Greenhouse (Leeds), a building with a waking watch from August 2020 to February 2021. The type of cladding that first drew attention was the specific kind used on Grenfell Tower, aluminium composite material (ACM) cladding. Scottish building regulations and planning law had prevented the extensive use of ACM cladding. While Welsh and Northern Irish law was similar to English, Wales had relatively few examples of ACM-clad high-rises, and by December 2018 had arranged remediation of them all, at the expense of the developers or building owners rather than leaseholders. In England, however, the Government had by 30 November 2019 identified 446 residential and publicly owned buildings over 18 metres in height 'with ACM cladding systems unlikely to meet Building Regulations' of the kind used on Grenfell Tower. At that time, 127 had completed remediation works, mostly social-sector and student accommodation blocks. It was estimated at that time that the remaining buildings comprised up to 23,600 flats and were inhabited by around 56,000 people. As of January 2021, the Government had identified 461 residential and publicly owned buildings in the same category; by that time, 329 had at least removed the cladding, including 231 that had completed remediation works, mostly social-sector and student accommodation blocks. Although reporting focused on residential buildings, other types were also affected, such as the 52-bed trauma unit at the John Radcliffe Hospital, Oxford, which closed temporarily due to concerns over flammable cladding on the building and other "serious and embedded" fire safety issues. It was also immediately apparent that some buildings had fire-safety issues other than cladding. For example, in August 2017, four 13-storey tower blocks built in 1968 to 1970, containing 242 flats, on the Ledbury estate in Peckham had their gas supplies cut off as a precaution: in the event of a gas explosion, they could be at risk of collapse, since they used the same "large panel system" as Ronan Point that had partly collapsed in May 1968 after a small gas explosion in a flat knocked out a load-bearing exterior wall. Wider problems , found similar problems in seven other buildings. Investigations in the wake of the Grenfell Tower inferno, the Barking Riverside fire in June 2019, and the Bolton Cube fire in November 2019 (which enveloped a building under 18 metres tall, which used combustible materials other than ACM cladding) led to the realisation that far more UK buildings than the ACM-clad ones were not fire-safe, partly due to materials being marketed as meeting regulations which in fact did not, and partly due to builders' failures to comply with regulations in design and construction. Problems included the combustibility of other cladding materials such as high-pressure laminate, combustible balconies, lack of firebreaks in the cavities between walls and insulation, non-regulation-compliant firedoors, and a wide range of other problems. In June 2020, the UK government offered what the trade magazine Inside Housing characterised as 'a very loose estimate of 1,700 buildings' in England alone which were over 18 metres and high-risk, requiring urgent remediation, despite the ACM-remediation works that had taken place up to that time. The Parliamentary Housing Committee noted that a further 9,600 buildings were likely to have combustible cladding. The scheme has drawn criticism for failing to address those living in buildings under 11 meters. ==Short-term responses==

A key short-term response to identifying unsafe construction in tall buildings was to change the fire evacuation policy. Most had been designed to contain a fire within a single flat, such that in the event of a fire, only the inhabitants of the relevant flat should evacuate. The Grenfell Fire showed how disastrous this policy could be in buildings which did not meet safety requirements. Evacuation policies were widely changed such that all inhabitants should evacuate in the event of a fire. A key problem with this change was that buildings' alarm systems were not designed to alert all residents to a fire and facilitate total evacuation. Until such alarm systems could be installed, buildings required a 24-hour 'waking watch' by fire wardens who patrolled the building checking for fire. In January 2021, the Ministry of Housing, Communities & Local Government found the median waking watch cost in England to be £11,361 per affected building per month, or £137 per dwelling. ==Confidence among mortgage lenders and insurers==

As the realisation grew, during 2019, that large numbers of buildings, of all heights, were likely to be subject to unknown fire-risks and remediation costs, mortgage-lenders concluded that they could not reliably lend money for the purchase of such properties. This led to collapse in sales of a significant proportion of the UK housing stock in late 2019 which as of February 2021 was unresolved. Since flats are often the first step on the UK housing ladder, this had consequences for the whole housing market; for example, the majority of first-time buyers who had bought property using the UK government's help to buy scheme found themselves unable to sell their properties. In December 2019, UK Finance, the Building Societies Association, and the Royal Institution of Chartered Surveyors introduced the requirement for an External Wall Fire Review (EWS1) of blocks 18 metres or taller to assess whether a property contained potentially dangerous materials. The number of properties needing an EWS1 form was roughly halved in November 2020 by a Government agreement with the relevant bodies that requirements for an EWS1 could be made less stringent. In January 2023, following new guidance by the Royal Institution of Chartered Surveyors, six major UK banks began lending on medium and high-rise flats affected by cladding. However, many individuals have reported continued difficulties in having mortgages accepted, with few sales successfully completing without cash buyers or significantly reduced valuations. Buildings insurance premiums also began to rise as insurers sought to cover their liabilities. ==Liability for remediation==

Most properties affected by the cladding crisis were owned by leaseholders, who in English law lease their property from the freeholder of the building, the party which owns the ground on which the building stands and is by default responsible for the building's upkeep and safety. Most leaseholders were subject to leases that made them rather than freeholders responsible for paying for remedial works. In some cases builders or other parties which had broken the law in building non-regulatory-compliant buildings had gone out of business, and there was general pessimism as to the possibility of recovering costs from builders, including on the part of the National Audit Office and the Ministry of Housing, Communities and Local Government. In March 2019, it emerged that central government provisions for local councils to take charge of privately owned buildings to ensure safe cladding were failing in approximately 90% of cases, leaving tens of thousands of households stuck in buildings with unsafe cladding. Effects on leaseholders Progress on remediating ACM cladding problems was slow, especially in the private sector. A survey performed by the UK Cladding Action Group (UKCAG) found that many of these residents still faced high bills to replace the cladding due to government funds being withheld; in some cases residents were paying for waking watches; and residents' mental health in many cases had suffered. In July 2020, the government estimated that the average cost to leaseholders to implement remediation in unsafe buildings over 18 metres tall would be £9,000. By contrast, a survey of 1,342 leaseholders by Inside Housing in February 2021 found that around 90% of respondents expected to pay over £10,000, with 62.5% facing a total bill of above £30,000. December 2020 saw the first case of a leaseholder being bankrupted by costs associated with the crisis, and according to Inside Housing's survey, 17.2% were exploring bankruptcy options. Campaigning Leaseholders organised to lobby the Westminster government to remedy the situation. Government relief for affected leaseholders In May 2018, the government announced funding of £400m for the replacement of ACM cladding on social housing over 18m tall. The government followed this in May 2019 with £200 million of funding for remediation of ACM cladding on high-rise buildings in the private sector. A year later, it pledged £200m towards making similar replacements on privately owned blocks. On 26 May 2020 the government announced £1 billion to replace "unsafe non-ACM cladding on residential buildings that are 18 metres and over and do not comply with building regulations". On 31 January 2021 the government Waking Watch Relief Fund of £30 million opened. This paid for buildings to install alarm systems consistent with evacuating residents in the event of a fire rather than them staying in place (though not for the cost of waking watches themselves). On 10 February 2021 the Government announced a 'five point plan' and £3.5 billion cladding replacement fund. This would pay to remove 'unsafe cladding' from buildings over 18 metres; provide 'a long-term, low interest, government-backed' loan-scheme for leaseholders in 11–18 metre buildings to pay to replace their cladding (paying back no more than £50 per calendar month); and provided nothing for lower buildings or remediation of other expensive fire-safety problems such as a lack of fire-breaks in the cavity between the walls and the cladding, balconies, waking watches, or non-compliant fire-escape routes. Building Safety Bill and McPartland-Smith Amendments The Building Safety Bill was introduced in the House of Commons on 5 July 2021. The McPartland-Smith Amendments are amendments to the bill which were tabled by Conservative rebels Stephen McPartland and Royston Smith. The amendments include zero-VAT rating for all remediation work and waking watch costs, a government-backed insurance scheme, and legislative protection to prevent costs being passed down to leaseholders. Amendment NC4 requires the government to create a fund into which all builders of higher-risk buildings, residential mortgage lenders and residential building insurers must make contributions. No builder will be able to obtain building control approval to construct any building unless it becomes a member of the scheme and pays its dues. Leaseholders and leaseholder representative groups giving evidence to the Public Bill Committees said the Smith-McPartland amendment on a Building Safety Indemnity Scheme (NC4) will help leaseholders. Fox Amendment The Fox Amendment is an amendment to the UK Fire Safety Bill tabled by Liam Fox as a partial resolution to the UK cladding crisis. The amendment, based on the polluter pays principle and part IIA of the Environmental Protection Act 1990, requires builders to pay remediation costs if their buildings were not compliant with building regulations in force at the time of construction. The Fire Safety Act 2021 received royal assent on 29 April 2021. ==Devolved administrations==
