A cladding specialist faces over £100m in High Court claims regarding historic StoTherm Classic insulation installations prior to going into administration.
A specialist sub-contractor involved in historic cladding installations has been targeted with High Court claims exceeding £100m shortly before entering administration. The legal actions centre on historic installations of the StoTherm Classic external wall insulation system, with claimants seeking to recover substantial remediation costs and alleged financial losses across five separate court cases.
The scale of these claims underscores the massive financial exposure still facing the UK construction supply chain regarding legacy building safety and facade work. As main contractors, building owners, and developer groups attempt to recoup remediation expenses, the resulting legal costs and liabilities are pushing sub-contractors and specialist installers into insolvency. This collapse illustrates the persistent friction within the sector as historic insulation and cladding specifications are re-evaluated under strict building safety standards.
What does this mean for a UK tradesperson or DIYer actually buying this kit — does it change what they should pay, buy, or watch out for?
While this case involves large-scale commercial contracts rather than off-the-shelf retail purchasing, it directly impacts how tradespeople select rendering, insulation, and external wall systems from merchants like Travis Perkins or specialist distributors. Installers must ensure that any rendered insulation kit or facade material strictly aligns with current Building Regulations and manufacturer installation guidelines. When taking on retrofits or repair work on existing rendered systems like StoTherm, sub-contractors should verify that liability frameworks, sign-offs, and product guarantees are fully documented to avoid inheriting liability for historic installation faults.
