Latent Defects Insurance
Cost, Process & Underwriting Explained
Latent Defects Insurance
Latent Defects Insurance (LDI) is a core part of managing risk on any new‑build or conversion project. Far from a routine requirement, it plays a direct role in securing finance, protecting long‑term asset value, and giving lenders confidence that the development is properly safeguarded. It goes by a variety of names in the market: Structural Insurance, Structural Warranties, Building Warranties, but the insurance market calls it Latent Defects Insurance (LDI).
LDI is often treated as a checkbox for lenders or developers. In reality, it is one of the most commercially sensitive decisions you make on a project and, handled correctly, it reduces risk, supports funding, and protects long-term asset value. Handled poorly, it leads to delays, higher premiums, exclusions, or outright declines.
This comprehensive guide explains:

- Typical costs and pricing factors
- How underwriting decisions are really made
- The process from enquiry to policy issuance

What is Latent Defects Insurance?
Latent Defects Insurance provides long-term protection for up to 10-years from practical completion of the property (12-years for most Housing Associations) against structural defects arising from design, workmanship, or materials that were not apparent at completion but later cause physical damage.Â
It is primarily used for:Â
- Residential developments
- Mixed-use schemes
- Commercial property where lender security is critical
- Developer exit strategies requiring warranty-backed protection
LDI protects the asset itself rather than the contractor, making it attractive to lenders, investors, and future purchasers. The cover stays with the property during a sale and doesn’t need to be renewed during the 10-year term. Â
What LDI doesn’t cover
Structural Insurance typically doesn’t cover anything included in your standard Buildings Insurance which covers your home or property.
These include:
- Cosmetic issues
- Maintenance failures
- Contract disputes
- Internal water damage from faulty plumbing
- Any defect that would have, or should have been known at completion
The distinction matters – LDI is not a substitute for project management or quality control, and it is not a substitute for good standards.Â
Why developers work with us
We specialise in complex construction risks and understand how insurers assess projects behind the scenes. Our role is not just to obtain quotes – it is to position the project so underwriting decisions work in your favour. This includes:
Early risk positioning
Structuring submissions for underwriters
Aligning technical audits with insurer expectations
Managing lender requirements
How much does Latent Defects Insurance Cost?
Pricing varies significantly depending on risk profile. Most providers in the market will look at a number of factors when constructing your quote, including the type of build, the stage of construction, the experience of the team and the reinstatement value of the property in the event of a catastrophic failure. Two identical-looking projects on paper can receive very different pricing because underwriting focuses on delivery risk, not just design.Â
Typical UK premium ranges
In the United Kingdom, these costs can range anywhere from 0.6% to 1.5% of construction cost or reinstatement value (depending on which they use for their rating). Â
Additional fees included in LDI quotes
In addition to the premium and insurance premium tax (IPT) most LDI distributors will include a few other costs in your quote, these include but may not be limited to:Â
Inspection Costs
- These are typically mandated by the insurer of the Consumer Code (see below). Â
- Inspections are required to monitor the build and identify any potential defects. Â
The Consumer Code fee
- Most lenders require the distributor of LDI to have a CTSI (Chartered Trading Standards Institute) approved Consumer Code scheme.Â
- The Code usually provides benefits such as a Dispute Resolution Process, in the event that the eventual homeowner has any issues with the property that may need arbitrated. Â
Risk Management Fees
- These fees vary, but typically encompass the costs that the distributor incurs in administering the insurance programme. Â
- These distributors are often client facing, marketing driven businesses, so they carry a lot of staff costs, marketing, underwriting and technical teams. The risk management fees are essentially how they make money.
The LDI process - What to expect
LDI is an underwriting process rather than a simple purchase. It differs from almost all other insurance products available in terms of how it is sold, and how the insurance is actually structured.
Why LDI Differs from Other Insurance
When buying motor insurance, you would normally approach a broker or aggregator website, provide your details and you receive a quote. If you are happy with that quote, you pay your premium, and your vehicle goes on cover. That’s it.
This is not the case with LDI.
With residential Structural Insurance the ultimate beneficiary of the insurance is the homeowner at any stage during the 10-year term of the policy, but that homeowner has no input into choosing or buying that insurance.
How LDI inspections, certifications, and cover transfers work
The developer of a new property (or someone within their team, like a contractor or Quantity Surveyor) will agree the quote and pay the premium. The build is monitored by the LDI distributor’s inspection team and if it meets all of the required standards and no potential defects are identified, the Insurance Certificate is issued and the property will go on cover.
Once the developer sells the property, the cover is transferred to the purchaser who is able to claim against it while they are the legal owner of that home. This could be anything from a couple of months from when the policy was paid for, up to several years depending on the length of the build programme.
LDI and Mortgage Lender Requirements
The LDI market, particularly in the residential space, is driven by mortgage lenders. Anyone in the UK who is taking out a mortgage on a property less than 10-years old, will undoubtably be required to ensure that property has a 10-year LDI policy in place, or they will not lend on it.
This is not generally the case with commercial properties, or Build-To-Rent schemes, as they will not be subject to a residential mortgage. Many developers still elect to have the piece-of-mind associated with a policy, as a Latent Defect will often not be covered by any other type of insurance policy and, in the event of an issue, can be very costly.

Frequently Asked Questions
Our dedicated LDI specialists have compiled the questions most commonly fielded regarding LDIs and related topics.
LDI quotes usually include additional fees on top of the base premium and tax. Because the build must be monitored, inspection costs are typically mandated and included in your quote. Quotes also usually encompass a Consumer Code fee and the distributor's risk management fees.
The cover stays with the property itself, meaning it doesn't need to be renewed during the 10-year term. Once you sell the property, the cover is transferred to the new purchaser, who can claim against it while they are the legal owner.
No. Standard Structural Insurance does not cover cosmetic issues, maintenance failures, or internal water damage from faulty plumbing. It specifically covers structural defects arising from design, workmanship, or materials that were not apparent at completion.
Unlike residential homes—where anyone getting a mortgage on a property under 10 years old is required by lenders to have LDI —commercial and Build-To-Rent schemes are not generally subject to this strict lender requirement. However, many developers still elect to purchase it for peace of mind, as structural failures can be incredibly costly and are often not covered by other policies.
