The Grenfell Tower tragedy in June 2017 exposed serious failings in the UK's building safety regime, particularly around the use of combustible cladding materials on residential buildings. Since then, the government has introduced sweeping reforms through the Building Safety Act 2022 and associated regulations, creating new obligations for building owners and managers to assess and remediate unsafe cladding systems. If you own or manage a building with cladding, understanding your responsibilities is essential.
This guide explains the current regulatory landscape, the remediation process, available funding, and how rope access can help reduce the cost of both assessment and remediation work.
The Post-Grenfell Cladding Crisis
Following the Grenfell fire, which killed 72 people, the government initiated a programme of testing and inspection that revealed widespread use of combustible cladding materials on buildings across the UK. Aluminium composite material panels with polyethylene cores, similar to those on Grenfell Tower, were found on hundreds of buildings. Subsequent investigations revealed that other materials, including certain types of high-pressure laminate panels, rendered insulation systems with combustible insulation, and timber cladding, could also pose fire risks depending on the building's height and overall wall system design.
The scale of the problem is significant. Tens of thousands of buildings across England alone are estimated to have some form of cladding that may require assessment or remediation. The financial and human cost has been enormous, with leaseholders trapped in unsellable and unmortgageable properties for years while remediation programmes are developed and funded.
The Building Safety Act 2022
The Building Safety Act 2022 is the most significant reform of building safety legislation in decades. It created the Building Safety Regulator within the Health and Safety Executive, established a new regulatory regime for higher-risk buildings defined as residential buildings over 18 metres or seven storeys, and introduced new duties for building owners, known as accountable persons and principal accountable persons, to assess and manage building safety risks on an ongoing basis.
For cladding specifically, the Act and associated regulations require that higher-risk buildings are registered with the Building Safety Regulator, that a safety case report is prepared and maintained for each building, that building owners assess and manage risks including those from external wall systems, and that remediation is carried out where unsafe cladding is identified. The Act also introduced measures to protect leaseholders from the costs of remediation in many circumstances, placing responsibility on developers and building owners instead.
Who Is Responsible for Remediation?
Determining who is responsible for funding and carrying out cladding remediation depends on the specific circumstances of each building. For buildings over 11 metres in height, the Building Safety Act provides that leaseholders in most cases are protected from remediation costs. The responsibility falls first on the original developer, if they can be identified and are still in business. Where the developer cannot be held responsible, the building owner or freeholder bears the cost, provided they meet certain criteria regarding their corporate structure and assets.
Government funding is available for some buildings through the Building Safety Fund and the Cladding Safety Scheme. For buildings between 11 and 18 metres, a developer-funded scheme and a government-backed loan scheme are available to ensure that leaseholders do not face unaffordable costs. The details of funding eligibility and application processes are managed by the Department for Levelling Up, Housing and Communities and are subject to ongoing updates.
Types of Cladding That May Need Remediation
The types of cladding that may require remediation include aluminium composite material panels with polyethylene or other combustible cores, high-pressure laminate panels, certain external wall insulation systems with combustible insulation such as expanded polystyrene or polyurethane foam, timber and wood-based cladding panels on buildings over 18 metres, and any cladding system where the overall external wall construction fails to meet the required fire performance standard, typically assessed as part of an EWS1 survey.
It is important to note that the presence of these materials does not automatically mean remediation is required. The fire risk depends on the overall wall system design, including cavity barriers, the height of the building, and the proximity of the cladding to escape routes and other critical features. A professional assessment is required to determine whether remediation is necessary and what form it should take.
The Remediation Process
Cladding remediation typically follows a structured process. The first stage is assessment, which involves an EWS1 survey or equivalent fire safety assessment to determine the composition of the external wall system and its fire performance. This often requires intrusive investigation, with cladding panels removed at sample locations to examine the materials behind them. Rope access is the most practical method for this intrusive investigation work.
If remediation is required, the next stage is design, where a fire engineer and cladding specialist develop a remediation scheme. This may involve full removal and replacement of the cladding system, partial removal and replacement of specific components, or installation of additional fire barriers or other mitigation measures. The third stage is procurement, where a remediation contractor is appointed, usually through a competitive tender process. The final stage is the remediation works themselves, which depending on the building size and complexity may take several months to over a year.
Funding Options for Remediation
Several funding mechanisms are available for cladding remediation. The Building Safety Fund provides grants to cover the cost of remediating unsafe cladding on residential buildings over 18 metres in England. The Cladding Safety Scheme extends similar support. For buildings between 11 and 18 metres, a developer-led remediation scheme requires original developers to fund remediation, with a government-backed loan scheme available as a fallback. Social housing providers have access to the Social Housing Decarbonisation Fund and may be able to combine cladding remediation with energy efficiency improvements.
Building owners should seek specialist advice on funding eligibility, as the landscape is complex and evolving. Professional managing agents and specialist cladding consultants can help navigate the application process and ensure that all available funding is accessed.
How Rope Access Reduces Remediation Costs
Rope access can significantly reduce the cost of cladding remediation, particularly during the assessment and smaller-scale remediation phases. For intrusive EWS1 surveys, rope access eliminates the need for scaffolding to access sample locations, saving tens of thousands of pounds on a typical building. For remediation schemes that involve targeted replacement of specific panels or components rather than full recladding, rope access teams can carry out the work at a fraction of the scaffolding cost.
Even on larger full remediation projects where scaffolding is ultimately required for the main works, rope access can be used for the initial survey and design phases, for carrying out preparatory work before scaffolding is erected, and for snagging and completion inspections after scaffolding is removed. By using rope access strategically alongside scaffolding, building owners can reduce overall project costs by 15 to 25 percent compared to a scaffolding-only approach.
Choosing a Remediation Contractor
Selecting the right contractor for cladding remediation is critical. Look for contractors with specific experience in cladding remediation, not just general building contractors. They should be able to demonstrate experience with the specific cladding system on your building, hold relevant accreditations, and have a track record of completing remediation projects on time and within budget. Check their IRATA membership if they are providing rope access services, and ensure they carry adequate insurance for the scale and nature of the work.
Timeline and What to Expect
Cladding remediation is typically a lengthy process. From initial assessment to completion of works, the timeline can range from 12 months for a straightforward project to three years or more for complex buildings or those requiring significant design development. The assessment phase alone can take three to six months including the EWS1 survey, fire engineering analysis, and design of the remediation scheme. Building owners should plan accordingly and communicate realistic timelines to leaseholders and tenants.
