The Grenfell Prosecutions 2026: What Happens Next for Individuals and Organisations Under Investigation?

Nearly nine years after the Grenfell Tower fire claimed 72 lives, attention is beginning to shift from the findings of the public inquiry to the prospect of criminal prosecutions.

In May 2026, the Metropolitan Police confirmed that the investigation remains on course to submit its remaining files to the CPS by September 2026, with charging decisions expected before the tenth anniversary of the fire in June 2027.

By any measure, the scale of the investigation is extraordinary. Investigators have reviewed millions of documents, obtained thousands of witness statements and examined the role of hundreds of organisations and thousands of individuals connected with the refurbishment of the tower.

The Met has stated publicly that 57 individuals and 20 organisations are currently under investigation as suspects. The offences being considered include corporate manslaughter, gross negligence manslaughter, fraud, health and safety offences and misconduct in public office.

That marks an important turning point in the Grenfell story.

For years, the focus has been on the Inquiry’s findings of systemic failure, regulatory weakness and serious misconduct within parts of the construction and fire safety sectors. The next phase is different. Prosecutors must now decide whether there is sufficient evidence to establish criminal liability against specific organisations and individuals.

That distinction matters.

Public inquiries exist to establish facts, examine failings and make recommendations. They do not determine civil or criminal liability. Section 2 of the Inquiries Act 2005 makes that clear. However critical an inquiry report may be, prosecutors must still prove every element of any criminal offence to the criminal standard.

That is likely to be particularly difficult in a case of this complexity.

The decisions now under scrutiny were taken many years ago across multiple organisations, contractors, consultants and public bodies. Investigators will be examining procurement decisions, testing data, technical specifications, internal communications, governance structures and the extent to which safety concerns were understood or escalated at the relevant time.

The investigation therefore raises difficult questions not only about accountability, but also about evidence, organisational responsibility and procedural fairness. As the case moves closer to charging decisions, those issues are likely to become increasingly significant for organisations, insurers, senior executives and professionals connected to the refurbishment and wider construction sector.

Who May Face Criminal Exposure?

One of the striking features of the Grenfell investigation is the breadth of organisations and individuals potentially exposed to criminal scrutiny.

This is not a conventional health and safety prosecution arising from a single operational failure. The investigation concerns a long chain of decisions involving product manufacturers, contractors, consultants, regulators, housing bodies and fire safety professionals.

The Metropolitan Police has confirmed that investigators examined the role of approximately 15,000 individuals and 700 organisations during the course of the investigation.

Although no charging decisions have yet been made, the Inquiry’s findings suggest that scrutiny is likely to extend across a wide range of sectors and professional disciplines.

Those potentially affected may include:

• contractors and subcontractors involved in the refurbishment works;

• cladding and insulation manufacturers

• architects and façade consultants

• fire safety advisers and approved inspectors

• housing management organisations and local authority personnel

• procurement and compliance professionals

• senior executives and directors

• testing and certification bodies

• public officials involved in oversight or regulatory functions

Importantly, exposure may arise not only from operational conduct, but also from documentary and strategic decision-making over a number of years.

The Inquiry examined issues including product testing, certification, procurement decisions, fire risk assessments, regulatory interpretation, record keeping and communications between organisations and public authorities.

The Phase 2 report was particularly critical of parts of the construction products industry. The Inquiry concluded that certain manufacturers engaged in what it described as “systematic dishonesty” in relation to the testing and marketing of combustible cladding and insulation products.

For investigators, one of the central issues is likely to be how responsibility is attributed within fragmented decision-making structures. Large construction and refurbishment projects often involve layered contractual arrangements and overlapping responsibilities. Prosecutors will need to establish not simply what happened, but who knew what, when concerns were raised and whether any failures crossed the threshold from regulatory criticism into criminal conduct.

That distinction becomes especially important where senior individuals are concerned.

Under the Corporate Manslaughter and Corporate Homicide Act 2007, organisations themselves may face prosecution where the way in which activities were managed by senior management amounted to a gross breach of duty. Individual liability, however, requires prosecutors to establish personal conduct sufficiently serious to justify criminal sanction.

The passage of time will also present difficulties.

Many of the decisions now under scrutiny were taken years before the fire itself. Personnel have moved on, organisations have restructured and the regulatory landscape has changed considerably since the refurbishment took place.

At the same time, the reputational implications for those connected to the investigation are already significant. Even in the absence of criminal charges, organisations and professionals may face scrutiny from regulators, insurers, professional bodies, counterparties and the media.

What Offences Are Likely to Be Considered?

The Metropolitan Police has confirmed that investigators are considering a range of offences arising from the Grenfell Tower fire, including corporate manslaughter, gross negligence manslaughter, fraud, health and safety offences and misconduct in public office.

At this stage, no charges have been brought. However, the offences identified publicly by investigators provide a clear indication of the legal framework likely to shape the next stage of proceedings.

One of the key challenges for prosecutors will be distinguishing between serious regulatory failings and conduct capable of satisfying the criminal threshold.

Public inquiries often expose systemic weaknesses, governance failures and poor decision-making. Criminal liability is different. Prosecutors must prove specific legal elements against identifiable defendants beyond reasonable doubt.

Corporate Manslaughter

The most prominent offence under consideration is likely to be corporate manslaughter under the Corporate Manslaughter and Corporate Homicide Act 2007.

Under the Act, an organisation may be guilty where:

• it owed a relevant duty of care

• there was a gross breach of that duty

• the breach caused death

• the way in which senior management managed or organised the organisation’s activities formed a substantial element of the breach

The focus is therefore not simply on isolated mistakes, but on systems, governance and organisational management.

In the Grenfell context, that may include scrutiny of testing and certification procedures, procurement decisions, risk management systems, escalation processes and the extent of senior management oversight of safety issues.

Gross Negligence Manslaughter

Gross negligence manslaughter applies to individuals rather than organisations.

To secure a conviction, prosecutors must establish a duty of care, breach, causation, a serious and obvious risk of death and conduct so exceptionally bad as to amount to a criminal act or omission.

The threshold is deliberately high. The CPS guidance makes clear that serious professional failings or errors of judgment do not automatically amount to criminal conduct.

That may prove particularly significant in a case involving multiple organisations, overlapping duties and extended chains of decision-making.

Fraud and Misrepresentation

One of the most serious aspects of the Inquiry concerned allegations surrounding product testing, certification and marketing.

The Inquiry concluded that certain manufacturers manipulated testing processes and misrepresented the performance of combustible products.

Those findings have prompted obvious questions about potential fraud allegations.

Potential offences could arise under the Fraud Act 2006, including fraud by false representation or fraud by failing to disclose information.

Any prosecution, however, would still require investigators to establish who made the relevant representations, whether they were dishonest by criminal standards and whether the necessary knowledge and intent can be proved against specific defendants.

Health and Safety Offences

Health and safety offences are also likely to form a significant part of any prosecution strategy.

Unlike manslaughter offences, health and safety legislation focuses on whether organisations or duty holders failed to ensure safety so far as reasonably practicable.

In large-scale disasters, prosecutors frequently pursue health and safety offences alongside, or instead of, manslaughter allegations where evidential difficulties arise concerning causation or individual responsibility.

Misconduct in Public Office

The Metropolitan Police has also identified misconduct in public office as a possible offence under consideration.

That reflects the Inquiry’s examination of the role played by public authorities and officials involved in housing oversight and building safety.

Ultimately, the legal challenge for prosecutors will not simply be establishing that catastrophic failings occurred. That is already well understood. The difficulty lies in proving individual knowledge, causation, organisational responsibility and criminal intent within an exceptionally complex factual and regulatory landscape.

The Challenge of Historic Decision-Making

One of the most difficult aspects of the Grenfell investigation is that prosecutors are attempting to assess technical and organisational decision-making that took place many years before the fire.

The refurbishment was completed in 2016. Some of the decisions now under scrutiny may relate to regulatory standards, testing regimes and industry practices operating over an even longer period.

Unlike a conventional criminal investigation focused on a single event, the Grenfell investigation requires investigators to reconstruct decision-making across multiple organisations, contractual relationships, reporting structures and regulatory systems.

That creates obvious evidential difficulties.

Investigators will need to establish:

• what information was available to particular individuals at particular times

• whether relevant risks were understood

• whether concerns were escalated internally

• how responsibilities were allocated

• whether specific decisions materially contributed to the eventual outcome

Those questions are especially difficult where responsibility was distributed across numerous parties rather than concentrated within a single organisation or individual.

The passage of time creates further complications.

By the time any prosecutions are brought, many of the relevant events may be more than a decade old. Personnel have moved roles, organisations have changed structure and memories will inevitably have faded.

That is one reason why contemporaneous documents are likely to become so important.

Emails, technical reports, meeting notes, procurement records, testing data and internal communications may all become central evidential material.

The Metropolitan Police has already confirmed that investigators reviewed approximately 165 million electronic files and tens of thousands of exhibits.

Another important issue concerns the regulatory environment that existed at the time.

The Inquiry was highly critical of aspects of the building safety regime, including weaknesses in Approved Document B, problems with testing and certification systems and failures in regulatory oversight.

That context matters because criminal liability is assessed against the standards and knowledge reasonably expected at the relevant time, not simply through hindsight.

Defendants may argue that industry practice reflected the prevailing regulatory environment or that guidance was unclear and inconsistently interpreted.

Prosecutors, by contrast, are likely to focus on evidence suggesting awareness of fire risks, failures to escalate concerns or deliberate manipulation of testing processes.

The evidential battle is therefore unlikely to concern technical issues alone. Wider questions concerning governance, organisational culture and accountability are also likely to feature prominently.

The difficulties associated with historic investigations are not unique to Grenfell.

Hillsborough, the Post Office Horizon scandal and the Didcot Power Station collapse all demonstrate the challenges involved in converting public criticism and institutional failure into successful criminal prosecutions years after the underlying events.

Inquiry Findings and Criminal Proceedings

One of the most important distinctions in the Grenfell context is the difference between the role of a public inquiry and the function of criminal proceedings.

The Grenfell Tower Inquiry was established to investigate the circumstances leading to the fire, examine systemic failings and make recommendations aimed at preventing similar disasters in future.

It was not established to determine criminal guilt.

That point is reflected directly in section 2 of the Inquiries Act 2005, which makes clear that inquiry panels have no power to determine civil or criminal liability.

The Inquiry’s findings were extensive and, in some areas, highly critical. However, inquiry findings are not criminal verdicts.

The CPS and Metropolitan Police must still establish admissible evidence against specific defendants and prove every legal element of any offence beyond reasonable doubt.

Public inquiries are fundamentally different from criminal proceedings.

Their purpose is fact-finding, public accountability and systemic analysis. Criminal proceedings, by contrast, are governed by strict evidential rules, disclosure obligations and procedural safeguards.

One important issue concerns the Attorney General’s undertaking given to witnesses during the Inquiry.

The undertaking restricted the future use of certain oral evidence in criminal proceedings in order to address concerns about self-incrimination.

However, the protection was not unlimited.

It did not apply to documentary evidence, nor did it prevent investigators from pursuing independent evidence obtained from other sources.

That distinction may prove highly significant given the volume of internal communications, technical material and testing records examined during the Inquiry.

Disclosure is also likely to become a major issue in any future prosecutions.

Large-scale corporate investigations routinely generate disputes concerning unused material, privilege, technical evidence and disclosure obligations. Experience from Hillsborough and the Post Office Horizon litigation demonstrates how central disclosure issues can become in major public cases.

There is also the question of public scrutiny.

The Grenfell Inquiry has generated years of media reporting and political commentary. Many organisations and individuals connected to the refurbishment have already faced intense criticism in public.

Criminal proceedings, however, require liability to be determined solely on the basis of admissible evidence presented at trial.

That creates an obvious tension between public expectations of accountability and the fundamental requirement for a fair trial.

The Reputational Risk Begins Long Before Any Charge

For many organisations and individuals connected to the Grenfell investigation, the most immediate consequences may arise long before any criminal trial.

Large public disaster investigations create scrutiny extending well beyond the criminal courts.

Reputational exposure may arise through:

• media reporting

• inquiry findings

• regulator engagement

• shareholder pressure

• professional disciplinary proceedings

• contractual disputes

• insurer scrutiny

• public procurement consequences

Organisations may therefore find themselves dealing simultaneously with criminal investigation, regulatory scrutiny, civil litigation and reputational damage.

One particularly sensitive issue concerns the divergence of interests between organisations and individuals.

At the outset of an investigation, organisations and employees may appear broadly aligned. Over time, however, interests can diverge significantly, particularly where questions arise concerning governance, escalation procedures or individual knowledge of risk.

Potential tensions may involve:

• access to legal representation

• internal investigation findings

• disclosure obligations

• indemnity arrangements

• employment issues

• media strategy

Senior executives and technical staff may require independent legal advice where there is potential personal exposure.

Insurers and professional regulators are also likely to play an important role.

Issues concerning directors’ and officers’ insurance, professional indemnity cover, notification obligations and regulatory fitness to practise may all arise alongside the criminal investigation.

The media environment creates additional complexity.

Public statements, stakeholder communications and internal messaging may all attract scrutiny. Organisations therefore need to consider reputational strategy alongside legal strategy from a very early stage.

The Grenfell process demonstrates that reputational damage often begins long before any charging decision is made.

Why Early Strategic Advice Matters

As the investigation moves closer to potential charging decisions, organisations and individuals are increasingly likely to face difficult strategic decisions long before any prosecution is commenced.

In large-scale investigations, decisions taken early can have significant consequences later.

One important issue concerns legal professional privilege.

Internal reviews following major incidents may generate substantial amounts of sensitive material, including factual reports, interview records, technical analysis and governance reviews.

Whether that material attracts legal privilege can become critically important.

The law in this area has been examined closely in recent years, particularly following decisions such as Serious Fraud Office v Eurasian Natural Resources Corporation Ltd.

Organisations therefore need to think carefully about how internal investigations are structured, who is instructed and how material is created and circulated.

There are also difficult questions concerning the relationship between organisations and employees.

Internal investigations may create tension where individuals face potential personal exposure. Issues concerning independent representation, access to documents and conflicts of interest may arise quickly.

The Grenfell context is especially complex because it involves criminal investigation, public inquiry scrutiny, regulatory reform and civil litigation operating in parallel.

Document preservation is another critical issue.

Large investigations place significant emphasis on emails, messaging systems, technical reports, board minutes and internal communications.

Failure to preserve material properly can create obvious legal and reputational difficulties.

The Grenfell investigation also demonstrates how closely legal strategy and reputational strategy are now connected.

Public inquiries generate sustained public scrutiny, and reputational narratives can form rapidly through media reporting and public hearings.

Organisations therefore need to ensure that public communications are carefully aligned with legal strategy from the outset.

Wider Implications Beyond Grenfell

Although the Grenfell investigation is unique in its scale and consequences, its significance extends far beyond the organisations directly connected to the refurbishment.

The Inquiry’s findings, the criminal investigation and the Government’s subsequent reforms have already reshaped the legal and regulatory landscape surrounding building safety, governance and corporate accountability.

The most obvious example is the Building Safety Act 2022 and the wider programme of building safety reform.

The legislation introduced the Building Safety Regulator together with enhanced obligations relating to higher-risk buildings, regulatory oversight and accountability.

More broadly, there is an increasing focus on senior management responsibility and governance oversight.

Historically, prosecutors often faced difficulty attributing criminal liability to large organisations under the traditional “directing mind and will” doctrine.

The Economic Crime and Corporate Transparency Act 2023 introduced a broader “senior manager” attribution model for specified economic offences.

The Crime and Policing Act 2026 expands that approach further by creating a wider statutory route to corporate criminal liability. Once in force, the legislation will allow organisations potentially to incur liability where a senior manager commits an offence while acting within the actual or apparent scope of their authority.

The legislation will not apply retrospectively to the Grenfell events themselves. Nevertheless, it reflects a broader shift towards increased scrutiny of senior management accountability, governance structures and organisational oversight.

That direction of travel is increasingly clear.

Regulators, prosecutors, investors and insurers are placing greater emphasis on:

• governance quality

• risk management

• escalation procedures

• organisational culture

• demonstrable oversight of safety-critical issues

The Grenfell Inquiry’s findings concerning alleged dishonesty, safety culture and governance failures are likely to remain relevant well beyond the immediate construction sector.

Grenfell also sits within a broader pattern visible across other major public inquiries and scandals, including Hillsborough, the Post Office Horizon litigation and the UK Covid-19 Inquiry.

Collectively, those cases demonstrate an increasingly interventionist approach to institutional accountability within the UK.

Whether future Grenfell prosecutions ultimately succeed or fail, the case is likely to influence corporate governance, building safety enforcement and crisis management strategy for many years to come.

Conclusion

As the Grenfell investigation moves towards the anticipated charging phase, the legal landscape is entering a very different stage from the one that has dominated public attention over the past nine years.

The Inquiry has already delivered a detailed and highly critical account of systemic failure across elements of government, regulation, construction and fire safety oversight.

The criminal process presents a different challenge.

For prosecutors, the issue is no longer simply whether catastrophic failings occurred. The task now is to determine whether specific individuals and organisations can properly be said to bear criminal responsibility within an exceptionally complex factual, technical and regulatory environment.

At the same time, the wider implications of Grenfell are already clear.

The Inquiry and subsequent reforms have accelerated scrutiny of corporate governance, senior accountability and safety oversight across a range of sectors.

Grenfell is therefore likely to remain significant not only because of any future prosecutions, but because of what it reveals about the direction of modern corporate and regulatory enforcement in the United Kingdom.

For organisations and senior individuals operating in complex and highly regulated sectors, the lessons extend well beyond the facts of Grenfell itself.
