Mixed-use properties sit between two worlds. Standard commercial products don't want the residential component, and landlords insurers won't touch the commercial side. ISR bridges that gap.

Why Standard Products Fall Short

When you've got a shop on the ground floor and flats upstairs, most mainstream insurers don't know where to put it. Their systems are built around either residential or commercial - not both. So they decline it. We've placed mixed-use properties under ISR packages when standard products won't respond. The ISR route works because specialist underwriters assess the actual building and tenancy mix rather than trying to fit it into a category it doesn't belong in.

BI Needs Both Sides Covered

The business interruption side is especially important for mixed-use. You need rental income from both commercial and residential tenants protected, and the BI calculation needs to account for both. For general mixed-use property insurance options, see our mixed-use property insurance page. This page covers ISR placement for mixed-use buildings that need specialist underwriting.

WHY ISR FOR MIXED-USE

What makes mixed-use properties an ISR risk

Mixed-use buildings combine commercial and residential tenancies in a way that doesn't fit standard underwriting models. ISR underwriters have the capacity and appetite to cover the full building when standard products can't.

01

Dual Occupancy Classification

The building sits between commercial and residential underwriting - standard products struggle with this overlap. ISR underwriters assess the actual tenancy mix rather than trying to force it into one category or the other.

02

Commercial Tenant Risk Profiles

The type of commercial tenant directly affects the whole building's risk profile and insurability. A ground-floor cafe is a completely different proposition to a ground-floor accountant's office, and ISR underwriters price for the actual tenancy.

03

Complex BI Calculations

Rental income from residential and commercial tenants needs separate treatment in the business interruption section. Commercial leases and residential tenancies have different recovery timelines and indemnity period requirements.

04

Building Age and Fire Separation

Older buildings often lack modern fire separation between commercial and residential sections. ISR underwriters can work with this where standard products just decline. Fire compliance upgrades and heritage restrictions add complexity that needs specialist assessment.

QUESTIONS

Mixed-Use Property ISR Insurance FAQs

Standard insurer systems are built around two categories - residential and commercial. A building that's both creates a risk profile that doesn't fit either model. Rather than work it out, most just decline. ISR underwriters assess the actual building rather than trying to categorise it.
Our mixed-use property insurance page covers general insurance options for mixed-use buildings. This page is specifically about ISR placement - when your mixed-use property is too complex, too high-value, or has been declined by standard products and needs specialist underwriting.
Absolutely. A ground-floor office is very different from a ground-floor restaurant or takeaway shop. The commercial tenancy directly affects the fire risk, liability exposure, and overall insurability of the building. ISR underwriters assess the full tenancy schedule rather than declining on the worst tenant.
Yes. An ISR policy covers the entire building including both commercial and residential sections. Business interruption can be structured to cover loss of commercial rent and residential rent separately, with appropriate indemnity periods for each.
Heritage buildings with mixed-use tenancies are some of the hardest properties to place. ISR can accommodate heritage reinstatement requirements in the sum insured and policy terms. Getting a proper valuation that accounts for heritage rebuild costs is critical.
No. ISR is property-only. We arrange public liability and any other liability covers separately to sit alongside your ISR policy.
