Self-Build Insurance From The Ground Up

What Is Self-Build Site Insurance?

Self-Build Site Insurance is a specialist policy designed to protect your building project from the moment you purchase the plot, right through construction, and until the home is complete and ready to move into.

Whether you’re managing the build yourself or hiring contractors, this insurance gives you peace of mind by covering the risks that standard home or builder policies often don’t.

Why Your Project Needs Specialist Protection

Building or renovating a home is a major financial commitment, and things don’t always go to plan. Theft of materials, damage from storms, or liability claims can all result in unexpected costs.

A specialist policy fills the gaps left by home insurance and builder policies, giving you the comprehensive cover you need.

Public Liability Cover For Your Site

Accidents can happen, even before you’ve broken ground. Our Self-Build Site Insurance includes Public Liability cover, which protects you if a third party suffers injury or property damage on your site. It’s essential cover for anyone managing contractors or allowing visitors onto the premises during construction.

What Isn’t Covered

While the policy is comprehensive, it won’t cover every possible event. Exclusions typically include:

  • Wear and tear or poor workmanship
  • Existing structural issues which were not disclosed beforehand
  • Damage caused by negligence or unapproved alterations
  • Deliberate acts of vandalism by the policyholder

We’ll guide you through any specific exclusions at the quote stage to ensure full transparency.

If you’re managing your self-build, you’re responsible for the site and anyone working on it.

Those Contracting Out The Works

Not taking on the build yourself? Even when using a main contractor or builder, their insurance may only cover their liability, not your site, materials, or structure. You’ll still need your Site Insurance policy to ensure every aspect of your project is covered, especially if something goes wrong with subcontracted work or deliveries.

Developers And Small-Scale Builders

If you’re developing a small number of new-build properties for resale or investment, our Site Insurance policies can cover your work and liabilities up to a professional reinstatement cost of £1.5 million. It’s a smart safeguard for developers working on tight budgets and deadlines, offering financial protection for the unexpected.

Additional Protection – Structural Warranty

Site Insurance protects you during construction, but a Structural Warranty ensures your home remains covered long after building work is complete. It’s an essential part of safeguarding your investment for the future.

What Is A Structural
Warranty?

A Structural Warranty is a long-term insurance policy that covers defects in the design, workmanship, or materials of your new home or building once it’s finished. It typically lasts for 10 years and is often required by mortgage lenders and future buyers. This cover starts from completion and helps protect against costly structural repairs.

Why Arrange Your Structural Warranty Early

Your Structural Warranty must be in place before construction begins. This is because approved inspectors need to complete technical audits during key stages of the build, including groundwork, structure, and roofing. If you wait until after the build has started, you could face expensive retrospective survey costs or be refused cover altogether.

FAQs

Are Self-Build insurance and Site Insurance the same thing?

Yes, Site Insurance is also known as Self-Build Insurance but both types of cover are designed to protect you, your project and your employees from the start of your project until completion.

What is Site Insurance?

Site Insurance, also called Self-Build Insurance, is the insurance you need from the moment you start work until completion. Our policies cover new works, existing structures, employers’ liability, public liability, fire, theft, storm damage etc.

When should I take out Site Insurance?

You become responsible for insuring your plot of land as soon as the exchange of contracts has taken place. Site Insurance should be taken out at this point in time to at least cover your liabilities until the construction works begin, at which point the main body of the policy will automatically come into force.

If works are not going to start within 90 days, it would be advisable to take out Land Owners’ Liability cover to cover your Public Liability exposure until works are due to start, at which point Site Insurance should be arranged.

If you have an existing structure and are not going to start within 90 days you would need to arrange Unoccupied Buildings Insurance until the works are due to start, at which time Site Insurance needs to be arranged.

Doesn’t my builder have insurance?

Most builders will have some form of insurance, but this is often not comprehensive enough to cover your whole site. Many builders’ insurance policies have limits which won’t cover the whole cost of your build or your site if they are not on it.

You will also need to prove they have been negligent and pursue them in court at your own expense for a successful claim.

Is Site Insurance the same as a Structural Warranty?

No, Site Insurance covers your project while it is being built. A Structural Warranty covers all new structural works for 10 years from completion.

What is covered on the existing structure element of the policy?

It is very important that you protect the existing structure of any conversion, renovation or extension. Often a substantial amount of the project affects the existing structure and it is important that it is protected from similar perils to the new works. Occasionally you are able to purchase Aircraft, Fire and Explosion Cover only for existing structures but in many cases this is not adequate.

The Self-Build Zone policy can provide Consequential Damage Cover for all existing structures. This means that you are covered if the existing structure is damaged by new works. Please note that most household policies will not cover the existing structure whilst works are being carried out, or for damage caused by works that are being carried out.

What does Site Insurance cover?

Site Insurance is necessary to protect your investment when you’re carrying out a renovation, conversion, extension or new build. Our self-build Site Insurance policy covers the new work, existing structure and rest of the site.

It protects against the likes of losses, fire theft, flood, storm damage, vandalism and accidental damage. See the specific project pages for in-depth information on Self-Build Zone’s Site Insurance.

Do you need site insurance?

It is not a legal requirement to have Site Insurance, but you must by law have Employers’ Liability cover, as you will be employing contractors to work on your site. This is included within our policy at the value of £10m as standard.

It is always advisable to think about the worst thing that could happen during the build and think about the financial implications that would have. For example, without insurance, if your new house burnt down a week before you move in, who is going to pay to rebuild it?

How do I make a claim?

If you think you might need to make a claim, please phone our advisors on 0345 230 9874.

There is a claim form to complete, and we operate a 24-hour service number for genuine emergencies for Site Insurance and Warranty. Please see your policy document for excesses.

If you are unsure whether you need to make a claim, please call and you will be advised accordingly. All calls are recorded for legal and training purposes

Do I still need Site Insurance if I’m using a Main Contractor?

It’s important when hiring anyone for your self-build to look at their documentation.

If an employee or contractor claims to have their own insurance, always request a copy of their policy documents to check that their cover is sufficient to cover your project for reinstatement cost and while they are not on site.

What insurance do I need for a self-build?

When doing a self-build you will need:

  • Public Liability to protect you while you just own the plot.
  • Site Insurance when you are about to start works until completion.
  • A Structural Warranty to protect your build for 10 years post completion and allow you to meet the UK lender requirements.
  • Site Insurance and a Structural Warranty should be arranged up to 30 days before you start.

Do I need insurance for a self-build?

You need Public Liability for your plot pre-building work.

You will need Site Insurance during the build and a Structural Warranty on completion. Site Insurance and a Structural Warranty need to be arranged before you start.

What insurance do I need for building work?

If you are altering the structure of your home, it is often an exclusion on your Building Insurance property.

When you are ready to start works, you need Site Insurance to cover the existing structure and the new works being carried out. On completion you can reinstate your normal home and contents insurance policy.

Do you need Site Insurance?

Site Insurance is a must for anyone building or designing their own home. Your builder’s insurance may not cover the value of your plot and is often very limited in cover.

A Site Insurance policy covers your whole site including: public liability, employers’ liability, existing structure, theft, fire, flood, storm damage, hired plant, equipment etc.
