Insurance for Heritage-Listed and Older Mixed-Use Buildings

A heritage listing puts a mixed-use building outside every mainstream insurer's appetite in one move. So does an older build that has never been rewired. Both can still be placed. The product changes, the market changes, and the questions on this page are what the specialist underwriters ask.

THE SHORT ANSWER

A heritage-listed building with a shop or cafe below and residential above is usually outside every mainstream insurer's appetite, so the placement moves to an Industrial Special Risks (ISR) policy with a small number of specialist underwriters. Older buildings that have never been rewired or replumbed sit in the same hard basket. Older buildings that have been rewired and replumbed are placeable on a standard mixed-use policy. Our heritage and older-building placements in the past year ranged from around $3,000 to around $15,400 a year.

The gap between the bottom and the top of that range is the difference between an 1880s double-brick building with a professional office, and a 1920s heritage-listed building with a cafe. Age alone isn't the problem. Unrewired services under a commercial kitchen, and a rebuild obligation that has to satisfy a heritage authority, are.

WHY IT IS HARD

Why a heritage listing changes the product, not just the price

Mainstream mixed-use policies are written for buildings that can be rebuilt with standard materials by standard trades. A heritage listing removes that assumption. The rebuild has to satisfy a heritage authority, the materials and trades cost more, and the timeline is longer. Rather than price for that, the mainstream markets decline it and the building moves to underwriters who write complex property on an all-risks basis.

01

Rebuild obligation

A heritage listing can require like-for-like reinstatement of facades, joinery, roofing and detail. The sum insured has to be set on that basis, and mainstream wordings are not built for it.

02

Services under a kitchen

Original wiring and plumbing beneath a commercial tenancy is where the claims come from. The rewiring and replumbing dates are the first two questions every underwriter asks.

03

Fire separation

Older buildings often have timber floors, shared ceiling cavities and no fire-rated separation between the shop and the residence. Specialist underwriters can work with that; mainstream systems can't.

04

ISR is property only

An ISR policy covers the building and the rental income. Public liability for the owner is arranged as a separate policy alongside it, and we structure the two together.

BEFORE WE QUOTE

What underwriters ask about older buildings

These eight answers decide whether the building stays on a standard mixed-use policy or moves to ISR, and what it costs either way.

Year built, and whether the listing is local council, state register or facade only
When the building was last fully rewired, and the age of the switchboard
When it was last replumbed
Roof material and age (slate, terracotta, corrugated iron, Colorbond)
Wall construction (double brick, brick veneer, timber, rendered masonry)
Any asbestos, and whether it has been identified and managed
Fire separation between the commercial part and the residence
A rebuild valuation on a heritage basis, not a market valuation

QUESTIONS

Heritage and Older Mixed-Use Buildings - Frequently Asked Questions

In practice, yes. Every mainstream mixed-use market we work with declines heritage-listed buildings, so the placement moves to an Industrial Special Risks policy with a small number of specialist underwriters. It's a different product with a different structure: the ISR covers the property, and public liability is arranged separately alongside it. See ISR for mixed-use properties.
It still has to be declared, and some insurers will treat the whole building as heritage. Others will assess it on the actual construction and the rebuild obligation the listing creates. A facade-only listing on a building with modern services behind it can still place on a standard mixed-use policy with the right market. Tell us exactly what the listing covers.
Yes, and it's the same problem as heritage from the insurer's side: the wiring and plumbing are the claims risk, not the age itself. Outdated electrical and plumbing raise the likelihood of a fire or a burst pipe, and insurers either price that likelihood in or decline outright, so an older building that has never been rewired or replumbed usually sits outside mainstream appetite. The same building rewired and replumbed in the last decade or two is placeable on a standard mixed-use policy. If it hasn't been done, get a quote for the work; the rewiring date is the single answer that most changes which markets will look at the building.
On the cost to rebuild it in the way the listing requires, not on what it would sell for. Heritage-compliant materials, trades and approvals can push the rebuild cost well above a modern equivalent. An under-insured heritage building is the worst outcome at claim time, so we ask for a rebuild valuation on a heritage basis before we go to market.
Yes. The ISR covers the whole building including the residence, and the business interruption section can be set up to cover commercial rent and residential rent separately with different indemnity periods. Liability is the part that sits outside the ISR and is arranged as a separate policy.
Usually around three weeks, because each specialist underwriter assesses the risk individually. With all the information in hand and a client who can answer underwriter questions quickly, we've done heritage placements within 48 hours. If you have a settlement or expiry date, tell us first and we'll sequence the markets around it.
