Combined engineering insurance is the engineering insurance policy structure that packages multiple sub-classes — machinery breakdown, computer breakdown, boiler and pressure vessel inspection, lift inspection, electrical inspection and electronic equipment — into a single integrated policy with consolidated administration, premium and claims handling.
Category: Engineering specialty Also known as: combined engineering policy, engineering combined First codified: UK market practice from c.1970s as engineering sub-classes consolidated Related legislation: Pressure Systems Safety Regulations 2000 [1]; Lifting Operations and Lifting Equipment Regulations 1998 [2]; Electricity at Work Regulations 1989 [3]; Insurance Act 2015 [4]
Combined engineering insurance is the dominant policy structure for UK commercial and industrial customers requiring multiple engineering covers. The policy integrates the various engineering sub-classes into a single contract with unified administration, allowing the insurer’s engineering surveyor to perform the full range of statutory inspections on a single site visit and providing the insured with a single annual renewal, a single premium and a single point of contact for claims [5][6].
The principal sections of a typical combined engineering policy are:
Section A — Sudden and unforeseen damage: cover for sudden and accidental physical damage to plant and machinery from mechanical, electrical or electronic breakdown.
Section B — Engineering inspection: the statutory inspection services for boilers and pressure vessels (PSSR), lifting equipment (LOLER) and electrical installations (EAWR/BS 7671).
Section C — Computer and electronic equipment: cover for IT and electronic equipment from breakdown plus data restoration and increased costs of working.
Section D — Loss of profits following machinery breakdown: business interruption cover for losses arising from covered breakdown events. See loss of profits following machinery breakdown.
Section E — Deterioration of stock: cover for stock deterioration following breakdown of refrigeration or environmental control plant. See frozen food deterioration insurance.
Section F — Additional covers: extensions for specific exposures (third party liability for lift accidents, accidental damage from external causes, transit damage to specified items, etc.) [5][6].
The structure is particularly suitable for medium-sized commercial and industrial operators with mixed engineering plant. Smaller operators may use a more basic version covering only the essential inspection-related items; larger industrial operators may break out specific sub-classes into separate placements for cost or coverage reasons [5][6].
Combined engineering insurance is governed by the same statutory inspection regimes as the individual sub-classes: PSSR 2000 (boilers and pressure vessels), LOLER 1998 (lifting equipment), EAWR 1989 and BS 7671 (electrical installations). The ‘competent person’ role under each regime is typically performed by the same engineering surveyor under the integrated policy structure [1][2][3].
The Insurance Act 2015 governs the duty of fair presentation and warranty rules for non-consumer combined engineering insurance placements. The duty applies in the same way as for the individual sub-classes, with disclosure required of all material circumstances known or which ought to be known by the insured [4].
The Health and Safety at Work etc. Act 1974 and supporting regulations apply across the engineering insurance landscape, with the HSE as the principal regulator for the inspection-regulated plant covered under the combined policy. The Provision and Use of Work Equipment Regulations 1998 (PUWER) provide the general framework for safe use of work equipment, complementing the specific PSSR, LOLER and EAWR regimes [7][8].
For combined engineering policies covering operators in specific regulated sectors (healthcare under CQC; care homes under CQC; education under Ofsted; food production under FSA), the relevant sectoral regulators may have specific equipment standards that interact with the engineering insurance regime. The insurer’s surveyor typically engages with the sectoral regulator’s requirements as part of the integrated service [5][6].
A UK commercial customer arranges combined engineering insurance through a commercial broker, with the placement typically going to one of the specialist engineering insurers (Allianz Engineering, Zurich Engineering, RSA Engineering, HSB Engineering, Aviva Engineering). The insurer’s surveyor visits the premises (typically annually for combined commercial sites; more frequently for industrial sites with higher inspection cadences) and carries out the full range of statutory inspections relevant to the insured equipment [5][6].
The schedule of insured items lists the plant by class (boilers, pressure vessels, lifts, electrical installations, machinery, computers, etc.) with the relevant inspection schedule and the corresponding insurance cover. The schedule is updated annually at renewal to reflect plant additions, disposals and changes in use [5][6].
Premium for combined engineering insurance is typically a single annual sum reflecting the combined inspection and insurance services. For a medium-sized commercial operator, the annual premium might be £5,000–£25,000 depending on plant content; for a major industrial operator, £25,000–£200,000 or more. The premium includes both the inspection service (a significant component for inspection-heavy plant) and the breakdown insurance cover [5][6].
Claims handling under combined engineering is streamlined by the single-point-of-contact structure. The same engineering surveyor who has been inspecting the plant typically also acts as the loss adjuster for breakdown claims, providing technical expertise informed by detailed inspection records. The arrangement supports efficient claims handling and helps avoid coverage disputes about the cause of breakdown [5][6].
Standard combined engineering: dominant structure for typical UK commercial and industrial operators.
Office and retail combined: simplified product for office and retail operators with limited plant content (typically lifts, electrical installation, computer equipment).

Healthcare combined engineering: tailored product for healthcare providers including medical equipment cover and specific NHS / private healthcare regulatory considerations.
Educational sector combined: tailored product for schools, colleges and universities including science laboratory equipment, sports facilities equipment and IT estate.
Hospitality combined: tailored product for hotels and restaurants including refrigeration plant, lift installations, catering equipment and electrical installations.
Multi-site combined engineering: enterprise-level product for organisations with multiple sites, providing consistent cover across the estate with central administration.
Property managing agent combined: product designed for managing agents responsible for engineering risks across a portfolio of let properties.
A UK educational institution operates a multi-site campus with substantial engineering plant including 12 passenger and goods lifts, two steam boilers, multiple pressure systems in science laboratories, extensive electrical installations across nine buildings, science laboratory equipment, sports facility plant (including swimming pool), IT estate of approximately 800 computers and 40 servers, and catering equipment in three dining facilities. The institution places combined engineering insurance with a major engineering insurer, with the surveyor visiting the campus on a planned schedule to carry out the various statutory inspections (lift inspections 6-monthly; boiler inspections 14-monthly; electrical inspections 5-yearly per building) and providing breakdown insurance for the full range of equipment. Annual premium for the combined inspection and insurance is approximately £38,000. The policy provides aggregate cover limits across the various sections with sub-limits for specific items. Figures in this example are illustrative.
