Builders risk vs homeowners insurance comes down to what is being protected: homeowners insurance is usually designed for a finished, lived-in home, while builders risk insurance is designed for construction or renovation risks while work is underway.
A normal home insurance policy may not automatically cover all risks linked to building work, renovation, extensions, structural changes, an open construction site or contractors working at the property.
We help builders, contractors and construction businesses arrange suitable cover, and can explain where different types of insurance may fit before work starts.
Key Takeaways
Builders risk insurance covers buildings and materials during construction or renovation, protecting works in progress and site-specific risks.
Buildings insurance typically covers finished, occupied homes but may exclude major building works or contractor-related risks.
Builders risk insurance should be purchased before construction starts and is usually held in the property owner’s name to avoid disputes.
Builders and contractors need their own insurance, including public liability, tools cover, and contract works insurance where relevant.
Homeowners should check their builder’s insurance and confirm responsibility for insuring the works before construction begins.
Construction insurance in the UK can be complex, so seeking advice from an experienced broker like RAW Insurance helps ensure adequate and appropriate cover.
Builders Risk Insurance Explained
Builders risk insurance explained simply: it is insurance for construction projects or buildings while work is taking place. It protects buildings and structures during the construction or renovation process, including materials, fixtures and equipment that are intended to be permanently installed.
For a UK audience, similar insurance needs may be met through products such as:
Contract works insurance
Contractors all risks insurance
Site insurance
Renovation insurance
These are not always identical. Policy wording, responsibility, exclusions, limits and who needs to arrange the cover can vary depending on the project, the contracts and the insurance company.
A builders risk insurance policy is usually focused on physical loss or damage to the building project, works in progress, building materials, temporary structures, fixtures, equipment and sometimes property in transit. Builders insurance is designed to be flexible, accommodating unique construction risks, and can cover various aspects such as materials and supplies, property in transit, and debris removal costs after a loss.
Builders risk insurance should be purchased before or on the date of construction when the contract is finalised, and it is essential to secure coverage by the time materials are delivered to the construction site. If construction begins without builders risk coverage, the percentage of construction completed and the total completed value will be needed for the application process, with projects over 30% complete subject to additional underwriting review.
Most insurance providers will not underwrite a building if it is not complete, making a builders risk coverage form the best insurance option when the project is less than 30% complete. This type of insurance typically does not cover land, certain weather events, or accidents, and is best held in the property owner's name to avoid disputes.
What Does Buildings Insurance Usually Cover?
Buildings insurance usually protects an existing home against risks such as fire, theft, escape of water, storm damage and other insured events, depending on the policy. Buildings insurance covers fully completed, occupied structures and includes protection for personal contents and personal liability.
A standard homeowners policy is a long-term, renewable insurance that requires the property to be finished and lived in. It is intended for a stable existing structure, not necessarily a construction site with open walls, scaffolding, contractors, temporary structures and building materials on site.
Building work can change the risk profile. Examples include:
Structural alterations
Extensions
Loft conversions
Unoccupied periods
Open walls, roofs or exposed areas
Contractors on site
Increased risk of accidental damage, theft or injury
Standard homeowners policies typically exclude coverage for major structural renovations or construction because of elevated risks on an open construction site. Occupancy and use requirements differ between homeowners insurance and builders risk insurance, with the latter strictly for unoccupied sites under renovation.
Homeowners should speak to their insurer before building work starts. If the insurance company is not told about construction or renovation work, there may be coverage gaps, an additional premium may apply, or a later claim may be more difficult.
Builders Risk vs Buildings Insurance: The Main Difference
The main difference is policy focus. Buildings insurance usually protects the existing property and contents. Construction-related insurance is designed around risks created by building works.
Buildings insurance usually protects the existing building, contents and homeowner liability, subject to policy wording.
Builders risk insurance cover focuses on works in progress, building materials, fixtures and equipment connected to the project.
Builders insurance protects the builder or contractor against certain business risks.
A homeowner's policy may not cover contractor negligence or all site-related incidents.
A builder's policy may not protect the homeowner's existing structure unless specific cover is arranged.
Responsibility depends on contracts, policy wording and who is arranging the work.
Area | Buildings Insurance | Builders Risk / Construction Insurance |
Existing property | Usually yes, subject to policy | May vary depending on cover |
Works in progress | Often limited or excluded | Often a key focus |
Tools and plant | Usually no | May be included if arranged |
Public liability | Usually limited to homeowner liability | Often relevant for contractors |
Contractor negligence | Usually not automatically covered | May be addressed through contractor cover |
Theft from site | May be limited | May be included depending on policy |
Most builders risk policies cover damages only to the property owned by the policyholder, and do not provide liability coverage for workplace accidents or injuries. Builders risk insurance specifically covers buildings and structures under construction, including materials and equipment, while general liability insurance protects against claims of property damage or bodily injury that occur on someone else's property.
Coverage Scope and Protection
Buildings Insurance Coverage
Buildings insurance is mainly there to protect the existing property and contents. It may cover the home against fire, theft, escape of water, storm damage and similar insured events, depending on the wording.
During construction or major renovation, that protection can become limited. Most policies are not intended to cover every risk created by structural changes, an exposed roof, a partly open building, a changing property value or contractors working on a job site.
Homeowners policies may exclude contractor activities, unfixed building materials and damage caused during the works. A homeowner should not assume that standard property policies will cover works in progress, tools, plant, temporary structures or materials waiting to be installed.
Construction Insurance Coverage
Construction insurance is designed for building work risks and construction activities. A builders risk policy or UK contract works policy may cover works in progress, materials on site, materials in transit, temporary structures and debris removal after a covered cause of physical loss.
Builders risk insurance generally covers materials, equipment and supplies on-site during construction, but it does not cover damages from natural disasters like floods or earthquakes unless specifically added as endorsements. Common exclusions in builders risk insurance policies include land, certain weather events and accidents, with additional coverage available for some excluded items at increased premiums.
Builders risk insurance typically does not cover workplace accidents, bodily injury or liability coverage, which must be obtained through a separate general liability insurance policy. In other words, if items sustain physical loss, a builders risk insurance policy may respond if the loss is within the policy terms; if someone is injured, liability insurance is usually the relevant protection.
Responsibility and Liability
Responsibility Area | Buildings Insurance Responsibility | Builders Insurance Responsibility |
Property Insurance | Homeowner is usually responsible for insuring their existing structure, contents, and personal liability, subject to policy terms. | Contractor is responsible for their own business insurance, including liability and tools cover suitable for their construction work. |
Coverage of Contractor Risks | May offer limited coverage for contractor negligence but often excludes site-related incidents caused by building works, machinery, or materials. | Public liability insurance protects against third party injury or property damage claims; builders risk insurance excludes liability claims. |
Insurance for Works in Progress | Typically not covered under homeowners insurance. | Builders risk insurance covers works in progress, materials on site, and temporary structures during construction projects. |
Liability Coverage | Covers homeowner liability, but usually limited for contractor-related incidents. | General liability insurance protects contractors against claims of injury or damage on job sites and remains active year-round. |
Responsibility Confirmation | Property owners should confirm who insures the works, existing building, and materials before construction begins. | Contractors may need contract works cover depending on project specifics and ownership of materials during construction. |
When Might Standard Home Insurance Not Be Enough?
Standard home insurance may not be enough when the project introduces risks that are outside the normal use of the property.
Common examples include:
Building an extension
Major renovation
Structural work
Roof work
Loft conversion
Property being left unoccupied
Contractors using tools, plant or machinery on site
Materials stored at the property
Damage caused during the works
Roof work and loft conversions can leave parts of the property exposed to weather. Structural work can affect the stability of the existing building. Extensions can increase the rebuild cost and property value. Stored materials can increase theft risk. Contractors using equipment on site can create risks that standard home insurance was not priced or intended to cover.
What Insurance Should Builders Have?
Builders and contractors should have insurance that reflects the work they do, the sites they work on and the clients they work for.
Common types of cover include:
Builders insurance for construction businesses and self-employed builders
Public liability insurance for third party property damage or bodily injury claims
Employers' liability insurance where staff are employed
Tools insurance for tools and equipment
Contract works or contractors all risks insurance where relevant
Professional indemnity insurance where design, advice or specifications are provided
Van or commercial vehicle insurance for business vehicles
Public liability coverage levels in construction-focused policies are often in the region of £1 million to £10 million depending on trade, project size and risk. Some contractors all risks products can include contract works sums insured of £10 million as standard, with options for more depending on project size, while own plant cover may start at around £1 million.
Builders risk insurance covers the building project itself, but it is not a substitute for liability insurance. General contractors, subcontractors and self-employed builders should check whether their insurance covers the real risks of the job site, including tools, plant, materials, contracts, clients and liability claims.
Should Homeowners Check Their Builder's Insurance?
Yes. Homeowners should ask their builder for proof of suitable insurance before work starts.
This is not about mistrust. It is about making sure the right protection is in place for the property owner, the builder and the project.
Homeowners may want to ask for:
Proof of public liability insurance
Employers' liability insurance if the builder has staff
Evidence of relevant construction or contract works cover where needed
Confirmation of who is responsible for insuring the works
Written confirmation before the project starts
It is also sensible to check dates, limits and whether the cover applies to the type of work being carried out. A builder may have insurance, but that does not automatically mean every part of the homeowner's property, every item on site or every possible claim is covered.

Frequently Asked Questions
What is builders' risk insurance?
Builders risk insurance is a term commonly used in the US for insurance that protects buildings and structures while construction or renovation work is taking place. In the UK, similar needs may be covered through contract works insurance, contractors all risks insurance, site insurance, renovation insurance or wider construction insurance.
These products are not always identical, so the wording, exclusions, limits and responsibility should always be checked.
Does homeowners insurance cover building work?
It depends on the policy and the type of work. Minor decorative work may be treated differently from structural alterations, extensions, roof work or loft conversions.
Homeowners should contact their insurer before work starts. Standard homeowners policies typically exclude coverage for major structural renovations or construction because of elevated risks on an open construction site.
What is the difference between builders risk insurance and homeowners insurance?
Buildings insurance usually covers the existing property, contents and personal liability in a completed, occupied home. Construction-related insurance is designed for risks linked to building works, such as works in progress, materials, fixtures and site-specific risks.
Builders risk insurance usually focuses on physical loss to the covered property, not liability claims or workplace accidents.
Do builders need their own insurance?
Yes. Builders often need public liability insurance, tools cover, employers' liability insurance if they employ staff, and other cover depending on the work.
They may also need contract works or contractors all risks insurance for certain projects, and professional indemnity insurance if they provide design, advice or specifications.
Should I check my builder has insurance?
Yes. Ask for proof of public liability insurance, employers' liability insurance if the builder has staff, and evidence of relevant contract works or construction cover where needed.
It is also sensible to get written confirmation of who is responsible for insuring the works before the project starts.
Can RAW Insurance help builders outside Cumbria?
Yes. RAW Insurance is based in Carlisle and Kendal, but supports builders, contractors, tradespeople and construction businesses across the UK.
