Unoccupied Under Construction Property Insurance
Properties that are unoccupied and under construction can face risks from fire, theft, vandalism, storm damage, escape of water, building materials, contractors, temporary works, plant, equipment, and liability claims. Standard unoccupied property cover may not be suitable where construction or renovation work is taking place.
Quote Monkey can help property owners, developers, contractors, landlords, and managing agents request a specialist broker referral for cover such as contract works, existing structures, public liability, property owners' liability, materials in transit, plant, tools, and renovation-related risks.
Referral enquiries may be reviewed by a specialist insurance broker, subject to underwriting criteria, insurer acceptance, terms and conditions.
Specialist Referral Support for Properties Under Construction
Unoccupied under construction property insurance is designed for properties that are vacant while building, renovation, conversion, extension, or refurbishment work is taking place.
Construction projects can involve a wider risk profile than ordinary vacant property, especially where contractors, materials, scaffolding, temporary works, exposed structures, hot works, or structural changes are involved. A specialist broker may be able to review the project and help identify suitable cover options.

Common Insurance Sections for Construction and Renovation Projects
Contract Works Insurance
Contract works insurance may help protect the works in progress, including materials, fixtures, fittings, and partially completed construction work against insured risks such as fire, theft, storm, flood, vandalism, or accidental damage.
Existing Structures Insurance
If you are renovating, extending, or converting an existing property, cover may be needed for the original structure as well as the new works. This can be important where standard property insurance excludes or restricts cover during building works.
Public Liability Insurance
Public liability insurance may help protect against claims if a visitor, neighbour, contractor, pedestrian, or member of the public is injured or their property is damaged because of the construction site or works.
Employers' Liability Insurance
If you employ workers, labourers, apprentices, site staff, or temporary helpers directly, employers' liability insurance may be legally required. Contractors should also hold their own insurance, but your own responsibilities should be reviewed carefully.
Plant, Tools and Materials Cover
Cover may be available for owned or hired-in plant, tools, materials, scaffolding, site equipment, and temporary works, depending on the policy and project details.
Who May Need This Cover?
Unoccupied under construction property insurance may be suitable for:
Property owners carrying out renovations
Landlords refurbishing empty properties
Developers converting or extending buildings
Homeowners undertaking major works before occupation
Commercial property owners refurbishing vacant premises
Builders working on empty sites or buildings
Probate properties undergoing repair before sale
Properties being converted to a new use
New build projects awaiting completion
Unoccupied properties with scaffolding, structural work, or contractors on site
Why Construction Projects Need Specialist Review
Building work can change the risk profile of a property. Open structures, exposed roofs, temporary electrics, hot works, contractors, storage of materials, scaffolding, and unfinished areas can all affect how insurers view the property.
Some standard property policies exclude or restrict cover when building work starts, especially if the property is unoccupied. It is important to disclose the works, project value, contractors, timescales, and site security so the correct type of cover can be reviewed.

Site Security, Inspections and Contractor Conditions
Policies for properties under construction may include conditions around site security, fencing, alarms, locked access, storage of materials, removal of waste, fire prevention, hot works procedures, contractor insurance, and regular inspections.
A specialist broker may ask about who is carrying out the works, whether contractors are insured, whether the site is secured, whether the property is watertight, whether utilities are connected, and whether any hazardous work is involved.
Materials, Plant and Property in Transit
Construction projects may involve materials, fixtures, fittings, plant, machinery, and tools being stored on site or transported to the property. Some policies may be able to consider materials on site or property in transit, subject to limits, security, and policy wording.
Hired-in plant, scaffolding, skips, temporary site buildings, and contractor-owned tools may require separate review. The insurance responsibilities between the property owner, main contractor, and subcontractors should be made clear before work starts.
Information a Specialist Broker May Ask For
To review an unoccupied under construction property insurance referral, a broker may ask for:
Property address, postcode, and construction details
Current property condition and previous use
Details of the building, renovation, conversion, or refurbishment work
Project start date, expected completion date, and contract value
Existing structure value and contract works value
Details of contractors, subcontractors, and their insurance
Whether the property is watertight and secure
Whether hot works, roofing, structural works, or demolition are involved
Site security, fencing, alarms, CCTV, and inspection arrangements
Whether materials, plant, scaffolding, or tools are kept on site
Whether public liability, employers' liability, or property owners' liability is required
What May Not Be Covered
Cover will depend on the insurer, policy wording, project details, contractors, security, exclusions, endorsements, and conditions. Common restricted or excluded areas may include:
Works not declared to the insurer
Faulty workmanship, defective design, or defective materials
Existing damage or known issues before cover starts
Failure to comply with site security or inspection conditions
Hot works unless agreed and controlled under policy conditions
Theft without forced or violent entry, depending on the policy
Uninsured contractors or activities outside the agreed project scope
Plant, tools, or materials unless the relevant cover is included
Public or employee injury claims unless liability cover is arranged
Always check the full policy wording, schedule, exclusions, endorsements, and conditions before relying on cover.
