# Latent Defects Insurance Cost

> Latent defects insurance cost is driven by build value, structure and inspection. Why it must be arranged before work starts.

## Key facts

- Latent defects cover is underwritten alongside the build, so the application has to be made before work starts rather than at completion.
- Cover typically runs 10 to 12 years from practical completion, and the exact period is a term of the policy rather than a market standard.
- The inspection regime is a cost and an enabler at once: more inspection raises the premium and is frequently what makes cover available at all.
- Conversions are underwritten more cautiously than new build because the retained structure was never inspected during its original construction.
- A developer's verifiable track record is one of the few drivers that reduces the premium and the only one that cannot be changed before applying.

## Data

- What drives the cost of UK latent defects cover, and when each is fixed, 2026. Methodology: This table describes the structure of latent defects and structural warranty cover as written in the UK market and the sequence in which decisions have to be taken. It quotes no premium and no rate, because this cover is rated individually on reinstatement value, construction type, the developer's record and the inspection regime required, and any figure published here would be illustrative rather than an offer. Cover periods are given as the typical range seen in this market rather than as a rule; the period is a term of whichever policy you buy. Where building control and regulatory duties are referenced, those are separate statutory matters from insurance and are pointed at rather than summarised, because they depend on the building and are for your own advisers.

## About

- Latent Defects Insurance Cost is an introducer site. We are NOT authorised or regulated by the Financial Conduct Authority, and we are not an insurer or a broker. We do not advise, arrange or recommend any policy, cover or provider: we introduce you to brokers and providers by passing your details to them, and they deal with you directly. We may be paid a commission for that introduction by the firm we introduce you to, and it never changes the premium you are quoted. Nothing here is insurance, legal or construction advice. No premium is published on this site because latent defects cover is rated individually on value, construction type, unit mix, track record and inspection. Cover periods are given as the typical market range rather than as a rule; the period is a term of whichever policy you buy. Building control and building safety duties are separate statutory matters from insurance and are for your own advisers. Check any broker or provider on the FCA's Financial Services Register before paying anything.
