Construction Insurance Broker Guide: What Specialist Underwriters Look For

Knowing how to present construction risks well is often the difference between a quick, favourable quote and a referral that drags on for weeks. This is where an experienced construction insurance broker earns their fee.

Underwriters don’t just assess the risk itself – they assess how clearly and completely it’s presented to them.

The quality of your risk presentation shapes not just whether you get a quote but whether the underwriter engages you as professional peer or an administrative burden.

Every detail matters. The gaps that trigger delays and the context that helps insurers understand a risk on its own terms — both shape the outcome.

In this guide you will learn how to present construction risks and other specific factors that underwriters look for from submissions like:

• The details to include in a well-presented construction submission
• The 8 most common construction insurance submission mistakes
• Why construction risks get declined and how to avoid it
• What our specialist underwriters expect from submissions

What a Well-Presented Construction Submission Includes

Before delving into what’s commonly missing from a submission, here is a checklist every construction insurance broker should work through before sending a risk to market:

• Project type and scope: the submission gives full project details
• Commercial: It states contract value, programme dates and project timeline
• Contract: it identifies the contract form; JCT, NEC, bespoke and flags any material amendments to standard conditions.
• Contractor: It profiles the contractor fully including company history, key personnel, relevant project experience and a financial summary.
• Design liability: it sets out any design responsibility on design and build contracts
• Fire and structural risk: it describes the fire strategy and cladding specification where relevant.
• Risk management: it explains the risk management and quality assurance processes in place
• Claims history: it covers claims history for the past three years, including the circumstances of any material claims
• Site-specific factor: pre-existing conditions or known complications on site are disclosed

These are the standard submission requirements. For more complex construction insurance risks like high-rise residential, cladding remediation and novel building methods other information is required.

To know how to present risks in the best way, you also need to know what to avoid. Here are the 8 most common mistakes our team of underwriters at Exance have picked up from submissions:

8 Construction Insurance Broker Submission Mistakes

1. Incomplete project timeline details

Underwriters need a comprehensive outline of the project programme include the start date, completion date, and any known extensions or phasing. A construction risk with an uncertain timeline is harder to price and harder to commit to. If you’re genuinely uncertain about the programme – explain why.

2. Missing contractor financials

Contractor credit risk is a material underwriting consideration. Submissions that don’t include recent financial statements, turnover information or any indication of financial health are deemed incomplete.

3. No acknowledgement of risk complexity

Risks that are hard to characterise like cladding exposure, design liability, a financially stretched contractor, unusual contract terms, must be stated in your submission.

4. Ambiguous contract liability allocation

Details like where design liability sits, who is responsible for sub-contractor works and the defects liability period should be clear – they have a direct effect on the scope of coverage and the price.

5. No risk management information

Two clients can look similar on paper and still carry different risk levels. The difference often comes down to investment in risk management: health and safety systems, quality assurance processes, and site supervision protocols.

Proper documentation of these details allows underwriters to assess the risk more favourably.

6. No clear claims history

Claims history gives underwriters the clearest real-world evidence of how risk behaves.

Providing underwriters with the full picture – not just figures, but the circumstances behind any material claims helps underwriters distinguish between a single claim with a clear cause and a genuine pattern of losses.

It impacts both the speed of a decision and the price attached to it.

7. Generic covering letter

A covering letter that summarises the submission, explains any unusual features, and contextualises the risk is a professional courtesy and a practical tool.

An underwriter who sees the risk in context before they open the documents is better positioned to make a positive decision than one who must piece it together from scratch.

8. Submission sent to the wrong market

If you submit a high-rise residential risk with cladding exposure to a standard commercial line’s insurer, you will get a decline that becomes part of the risk’s history. It’s best to know your market before you submit.

Why Construction Risks Get Declined and How to Avoid It

UK insurance law places a specific legal duty on submitting clear and complete documentation. Under the Insurance Act 2015, before a contract is entered in to, you must submit a fair presentation of the risk to the insurer.

A submission that is technically clear but poorly organised or lacks context can still fall short of this standard in practice.

Other reasons risks get declined include:

• Rising claims severity and thinner margins in the sector
• Water damage overtaking fire as the leading claims driver
• Softening rates masking harder underwriting discipline

We cover the structural reasons construction risks get declined in more detail in our dedicated broker guide.

As a baseline requirement you must present every material circumstance clearly. This means giving underwriters context, not just data: explain the reason behind the claim, document any changes and demonstrate how risk is actively managed on site.

It’s also worthwhile knowing the market before you submit, since underwriting appetite shifts quickly and sending a strong risk to the wrong insurer can produce a decline that has nothing to do with the risk itself.

A construction insurance broker who understands where a risk fits in the market avoids this mistake entirely.

Get all these factors right and underwriters have exactly what they need to say yes with confidence.

What Exance Underwriters Specifically Look For

At Exance we operate in the specialist segment of the construction insurance market – risks that require genuine underwriting expertise rather than automated risk scoring. This is exactly where a specialist construction insurance broker adds the most value.

Our underwriters bring specific construction knowledge to every submission, which means the criteria we apply are substantive rather than bureaucratic.

These construction insurance placement tips will give you an idea of what our underwriters look for from a submission:

• Evidence that the broker has assessed the risk themselves – not just forwarded a client questionnaire
• Clearly articulated risk complexity, including any challenging features
• Proactive disclosure of anything that might raise questions
• A risk management narrative that’s specific, not generic
• A clear understanding of the coverage required and why

We can say with confidence, that the construction insurance brokers who get the best outcomes with us are the ones who’ve done the work before they submit. That preparation pays off directly in the quality of the underwriting engagement.

If you have a construction risk that needs a substantive underwriting conversation rather than a form-driven process, submit it to Exance. We aim to respond within 48 hours.
