The London Engineering Group (LEG) has become affiliated with the International Underwriting Association, the two organisations said. The change gives the London-based engineering insurance group access to the IUA's secretariat for administrative support on its meetings and sub-groups.
LEG was established in 1984 and has operated independently as a forum for insurers covering engineering, plant, machinery and construction-related risks. Its activities have included technical discussion, education, and the publication of research, model clauses and guidance notes for the sector.
Construction All Risks and Engineering All Risks policies cover physical loss or damage during construction projects and to installed plant and machinery. Insurers writing those lines often rely on standardised clauses to define coverage, and LEG's model wordings have found wide use in that context.
The market those clauses apply to has shifted in recent renewals. A report from Gallagher Specialty found the global construction insurance market showing clear signs of softening, with premium reductions on well-performing annual contractor programmes.
Professional indemnity cover for construction professionals has softened even faster. Fire safety and cladding coverage, previously restricted, has started to return on a limited basis.
The IUA represents more than 80 London market companies and already runs committees across a range of other insurance classes. Chris Jones, the IUA's chief executive, said there is overlap between LEG's membership and IUA member companies.
Charlie Dee, UK construction underwriting manager at Berkshire Hathaway Specialty Insurance, chairs LEG. Dee said the affiliation would support the group's work on knowledge sharing and clause development.
LEG's model defect exclusion clauses are used internationally in Construction All Risks and Engineering All Risks policies. The IUA already operates an online clauses database for the wider London market.
The IUA expanded that resource last year. It launched an online library of more than 1,000 model insurance and reinsurance clauses in 2025. It also established a new Construction and Engineering Claims Committee for that class of business.
LEG's clauses and sub-groups will now sit alongside that existing structure. LEG's sub-groups, which focus on specific technical areas within engineering insurance, will continue to meet under the new administrative arrangement.
LEG will continue to run training sessions for its members, which will become part of the IUA's education programme.
That programme has grown recently. The IUA launched a NextGen Underwriting Committee in 2026 to support early-career underwriters. The committee is part of a broader IUA Futures initiative that already includes policy wordings masterclasses planned with the Clauses Committee.
LEG's presentations would add to that existing calendar of training content.
The IUA has established relationships with UK government departments, regulators and other trade bodies. It said those channels would now also be used to represent LEG members' interests.
The IUA has recently used those channels on behalf of its existing membership. It backed the Financial Conduct Authority's (FCA) proposals to streamline insurance conduct rules in 2025. It also pushed for clarity on how commercial policyholders are defined under the new framework.
It will also support the hosting of LEG's annual conference.
