Legal adviser HF has secured a High Court victory for a retired director, obtaining summary judgment to defeat a £3 million claim that sought to hold him personally liable under a personal guarantee signed nearly two decades earlier.
The case centred on an attempt by InstaGroup Limited to pursue HF's client under a 2008 guarantee, originally signed to support a modest goods-on-credit arrangement with Northwest Insulations Limited, now in liquidation.
Despite the director having retired in April 2022, the claimant sought to use that historic document to recover alleged losses arising from government-funded insulated schemes, complex service arrangements and indemnity and clawback provisions contained in a separate 2013 arrangement.
HF senior partner John Lord and associate Charlie Gray, alongside counsel Simon Vaughan, applied for summary judgment on three grounds: that the 2008 guarantee was strictly confined to liabilities arising from the supply of goods under the original credit facility; that it did not extend to service-based or indemnity liabilities under later agreements; and that any residual liability had been discharged by the 2013 agreement, which materially altered the commercial risk.
The claimant relied on broad "all monies" and "howsoever arising" language to argue for a wider scope.
The High Court rejected that approach, finding the guarantee properly confined to the original credit facility. It also held that even if it had applied more broadly, the 2013 agreement would have discharged it. The court concluded the claimant had no real prospect of success.
The case arrives against a backdrop of markedly elevated corporate insolvency in the UK.
In October 2025, the number of registered company insolvencies in England and Wales reached 2,029, about 7% higher than the same month in 2024. That surge has prompted a rise in claims under directors' and officers' (D&O), professional indemnity, and financial institution policies, with insurers facing tougher coverage disputes around exclusions, timing and aggregation issues. The increasing use of litigation funders is fueling claims that are better resourced and more aggressively pursued.
Demand for insolvency litigation finance continues to grow. In April 2025, there were 379 compulsory liquidations, a 61% increase in April 2023. That combination of elevated insolvency volumes and well-funded claimants is creating a more adversarial environment for directors, including retired ones who may believe their exposure ended when they stepped down.
The claim also reflects broader turbulence in the UK insulation industry. Government-funded schemes ECO4 and the Great British Insulation Scheme (GBIS) have faced serious controversy, with 39 businesses suspended from installing new solid wall insulation following widespread failures identified by independent audits.
A cross-party Public Accounts Committee report found that more than 30,000 homes had been left with defects, with around 98% of external wall insulation installed under ECO4 estimated to have major issues requiring remediation. That environment has generated disputes involving complex contractual chains, indemnities, and clawback provisions, precisely the kind of liabilities the claimant sought to attribute to HF's retired client.
The case also raised important questions about coverage gaps for directors facing claims under historic personal guarantees.
Standard D&O policies may provide limited or no protection in situations like this one. D&O policies typically exclude claims arising from contractual liabilities outside the scope of fiduciary duties, since a contractual obligation is voluntarily undertaken rather than imposed by law, an approach intended to prevent insurers from covering risks that are effectively contractual indemnities or guarantees.
This coverage gap means that the legal outcome of a case like this is, in practical terms, all that stands between a retired director and personal financial ruin.
